+establishes the replacement for cumulative journal and receipt limits. Current
+authority is maintained transactionally, completed action receipts are indexed,

+restartable three-store migration, and segmented stdout logs are implemented.
+Streamed body references and paged routing indexes avoid accumulating historical

+### Indexed receipt storage operations (experimental)
+
+Fresh local Codex sessions selected with `PAPERCLIP_NATIVE_INDEXED_STATE=1`
+use range-partitioned runner receipt stores. The following runnerd commands
+operate on an existing private store with its exact locator binding. They never
+print current authority or credential contents.
+
+```sh
+paperclip-runnerd storage partitions --path /private/session/runner-state.sqlite --binding 'runner/RUNNER_ID/SESSION_ID' --limit 32
+paperclip-runnerd storage maintain --path /private/session/runner-state.sqlite --binding 'runner/RUNNER_ID/SESSION_ID' --steps 100
+paperclip-runnerd storage relocate --path /private/session/runner-state.sqlite --binding 'runner/RUNNER_ID/SESSION_ID' --partition-start BASE64_START --destination /private/another-volume
+paperclip-runnerd storage backup --path /private/session/runner-state.sqlite --binding 'runner/RUNNER_ID/SESSION_ID' --destination /private/backups/snapshot-1
+```
+
+Partition inspection returns at most 128 entries, exact decimal counts, a base64
+`start` per range and `nextAfter` for the next `--after` page. The first range's
+start is the empty string; pass `--partition-start ''` when selecting it.
+Relocation requires an existing private destination directory. It starts a
+bounded copy with concurrent-write capture and atomic verified cutover; the
+running store continues maintenance between ordinary operations. The `maintain`
+command also advances at most the requested number of steps (maximum 1,000).
+
+Backup requires a new destination directory under an existing private parent.
+It publishes `authority.sqlite` and its relative receipt directory only after all
+snapshot ranges verify. Repeating an interrupted command with the same source
+and destination resumes its durable job. Live writes continue between bounded
+copy steps. Pinned retired partitions consume disk until the backup completes;
+failed backups retain their pins and staging evidence for recovery. A completed
+destination is never overwritten.
+
+Fresh standalone/evaluation controllers use this same partitioned engine behind
+a bounded private stdio subprocess. Their exact binding comes from the controller
+locator; the commands above also apply to those version-2 stores. Existing
+prototype version-1 controller files retain their original compatibility reader
+and writer. Production controllers continue to use Postgres.
+
+Read-only recovery inspection uses `paperclip-runnerd storage inspect-state
+--path /private/session/runner-state.json` (or `codex-provider-state.json`). It
+reads one current row under the existing lifetime fence and emits ordered,
+192 KiB base64 frames with an exact decimal generation, SHA-256 and required
+completion footer. Local inspection runs the same native command through a
+bounded worker and retains reader credit until the native child has closed;
+it does not open SQLite through a second host engine. SQLite owns database and
+sidecar descriptors: metadata validation must not open and close those files,
+which can release the process's POSIX SQLite locks. Consumers must verify the
+framing, digest and clean process
+exit. The output contains current session data; keep it private. It does not
+scan history, repair a store, checkpoint its WAL, or infer process retirement.
+
+For an already admitted quiet Codex session, `storage snapshot-session` accepts
+`--directory`, a new `--destination`, and `--runner-generation`,
+`--runner-sha256`, `--provider-generation`, `--provider-sha256` from that
+inspection. Both execution stores must be closed. The native operation holds
+both lifetime fences, checks suspended/settled state and session bindings,
+copies receipts in bounded batches (including relocated partitions), verifies
+all exact receipt identities and digests, and atomically publishes both stores
+with portable relative paths and an exact generation manifest. Repeating the
+same request resumes an interrupted copy; conflicting state or destinations
+fail closed. History-sized work has no aggregate command deadline. This is a
+maintenance backup, not a current-state read: its total I/O scales with the
+history being copied and verified.
+
+Published snapshot databases are sealed in rollback-journal mode before
+publication; read-only inspection must not create or alter WAL/SHM sidecars.
+Normal execution reopens a restored store in WAL mode. The outer harness
+manifest binds the exact runner/provider generations, digests and source run;
+restore checks those bindings and provider identity before accepting the
+streamed directory digests. A missing native snapshot marker cannot downgrade
+an indexed store to a legacy backup.
+
+The remote checkpoint consumer uses this native snapshot for indexed Codex
+stores instead of copying SQLite files from the runner directory. Native
+snapshots do not include the controller database, external payload storage, or
+provider home. Publishing a complete disaster-recovery backup still requires
+those resources to be bound to the same admitted recovery boundary. This work
+does not enable remote indexed execution or establish whole-session backup
+qualification.
+
+Every native store connection holds a shared lifetime lock until SQLite closes.
+Cold archival and stopped-runner sealing acquire an exclusive lock, and prepared
+archive intents prevent new opens until transfer finishes. An active or unfinished
+backup must finish before its source can be archived. Contention reports
+`storage_pressure` and preserves the current root for retry. Internal archive and
+seal commands are called only after the controller proves exclusive process
+ownership; a storage lock alone never supplies that proof.
+
+This backup captures one store. Restoring a live Paperclip session also requires
+the matching controller and provider recovery generation and independent process
+ownership verification; copying this directory alone does not authorize a second
+runner. Legacy JSON and version-1 single-file receipt stores are not converted
+by these operator commands. The rollout remains experimental and disabled for
+fresh sessions by default while migration activation, typed recovery consumers,
+provider/remote coverage and long-running qualifications remain incomplete.
+
+The complete history lifetime target contract, including transport epoch rotation,
+coordinated recovery generations and process containment, is specified in
+[Runner history over an unbounded lifetime](runner-history-lifetime.md). Its
+qualification matrix remains separate from individual component test results.

+# Runner history over an unbounded lifetime
+
+This is the target contract for history, receipts and recovery of long-running
+agents. Implementation and qualification are tracked in the dated
+[implementation record](../plans/2026-09-28-unbounded-runner-history.md).
+The local indexed Codex path is opt-in; this document does not declare the whole
+contract implemented or qualified.
+
+Paperclip uses the stock Codex distribution. A Paperclip-maintained Codex build
+is out of scope. Provider-owned replay and checkpoint limitations remain
+explicit limits of the stock-provider guarantee until upstream supports the
+required interfaces; this design does not hide them behind an unlimited claim.
+
+## What the product promises
+
+A task may accumulate history for days and continue for arbitrarily many turns.
+Completed work must never consume a lifetime allowance that eventually prevents
+the next operation. The same applies inside one active model turn. Adding
+storage does not change the task, provider session, pending call identities, or
+the meaning of an old receipt.
+
+“Unlimited” describes cumulative application limits. Available disk, storage
+throughput, provider context and service limits, and operator budgets still
+apply. An individual frame, current operation and unfinished delivery queue
+have finite admission limits. Those credits become available again when work
+settles. Exhausting storage preserves the exact task and pauses admission until
+capacity returns; it must not be reported as a mismatched or corrupt session.
+
+The mechanism has three parts:
+
+- **Current state** says who owns the task and what is unfinished. Ordinary
+  continuation reads this small record and bounded pages of outstanding work.
+- **History** contains past output. Writers append it; readers request pages
+  or stream downloads. Current execution does not reread old output.
+- **Receipts** remember the exact identity and result of completed actions.
+  A repeated action looks up one receipt in an index. An AI summary cannot
+  replace these records.
+
+With current work held constant, memory and foreground I/O have no linear
+dependence on historical bytes or completed action count. Indexed lookup can
+grow logarithmically, and storage/cache conditions can affect latency. A full
+export or disaster recovery may process historical bytes in the background;
+it cannot become a prerequisite for every review turn.
+
+## Authority and storage boundaries
+
+PostgreSQL is the controller's authority. The native runner owns transactional
+SQLite stores for runner and provider state. Immutable large bodies use the
+configured payload store. Provider-owned files remain provider state, not
+Paperclip action receipts. Each store's purpose is explicit; a locator, cached
+projection, output transcript or backup directory is never write authority.
+
+Each controller transaction validates company, issue, run, normalized session,
+runner and environment ownership. It commits current state, exact new receipts,
+outstanding-work changes and the accepted raw-event cursor together. The raw
+event is acknowledged only after that commit. Normalized UI delivery is a
+separate durable outbox; its cursor advances only with its consumer's commit.
+
+Local SQLite commits and reads run on owned storage executors, using qualified
+SQLite, bounded queues and WAL recovery. Partition routing is indexed. A
+receipt lookup never searches all prior files. Split and relocation operations
+are resumable, capture concurrent writes, and publish a new routing generation
+only after verification. The current routing head and any routing hierarchy
+must themselves support subdivision; an ever-growing root manifest is not an
+acceptable substitute for partitioning.
+
+The candidate routing implementation uses a B+tree of bounded, immutable pages.
+Only its bounded top page lives in the root SQLite transaction. That page also
+subdivides; point lookup follows one verified path, and each child is bound by
+its digest and range. Oversized receipt ranges are found through per-child
+maximum sizes, without a growing split queue. Retired-file inventory uses the
+same paged structure. These routing changes require their own qualification;
+earlier evidence for the flat `receipt_routes` preview does not qualify them.
+Obsolete immutable routing pages are collected in bounded write and idle
+maintenance steps. Reads do not trigger collection, and idle work yields
+between pages when a foreground request arrives.
+Each page supplies its immutable lower key and tree level; point lookups in the
+current routing and retired-file roots determine whether it remains reachable.
+The operation fence covers that check and deletion. An unfinished backup pins
+all source pages, and an unfinished write prevents collection until recovery.
+Only exact owned temporary names can be removed without a page lookup.
+Corrupt pages, unknown roots and symlinks fail closed.
+
+The collector retains at most three directory iterators and reads one page per
+step, plus logarithmic current-root lookups. A restart may repeat its scan;
+it never reuses a stale deletion decision. A complete sweep still takes time
+proportional to stored index files, but is not a continuation prerequisite.
+Space reclamation depends on maintenance throughput and backup pin lifetime.
+This collects index pages, not historical action receipts or payload objects.
+
+Paperclip business-tool receipts likewise live in indexed, company/run-bound
+database rows. Each action commits its receipt with its business mutation;
+continuation never appends to an ever-growing run JSON map. Publication and
+reuse references use indexed lookups. A server-derived comment flag and partial
+index locate the final response without scanning all earlier progress comments.
+The one-time receipt/comment migration preserves malformed legacy receipts as
+integrity failures and requires a maintenance window for its history-sized
+backfill and index creation.
+
+Large outputs are immutable segments with company-scoped identities, sizes and
+digests. Publication follows durable upload, so metadata never refers to an
+incomplete body. The user-facing API resolves references through normal task
+authorization and redaction. It does not expose arbitrary filesystem paths or
+unscoped object-store URLs.
+
+## Counters rotate independently of agent work
+
+Every accumulating counter must be classified before enabling the full mode.
+Increasing an integer width only postpones a ceiling. The following identities
+must remain distinct:
+
+| Identity | Meaning | What changes it |
+| --- | --- | --- |
+| Task / normalized session | The user's continuing work | Explicit product lifecycle |
+| Run / provider turn | One execution or provider turn | Normal run lifecycle |
+| Transport epoch | A bounded sequence namespace for one delivery lane | Internal cursor rotation |
+| Authority revision | Exact compare-and-swap identity of current state | Durable state mutation |
+| Partition generation | The authoritative route for a key range | Storage administration |
+
+A cursor is `{ epochId, ordinal }`. The epoch is an opaque unique identity;
+the ordinal is an exact, bounded integer represented without JavaScript
+rounding. Epochs are stored as indexed records with predecessor/successor links,
+final ordinal and an exact transition receipt. The current head points directly
+to the current epoch. Reading after an old cursor starts at that exact epoch,
+then follows successors as needed for the requested page. It never reconstructs
+the entire chain first. History receipts remain indexed by their original epoch.
+
+Rotation uses a separately negotiated capability. It must not silently change
+the interpretation of existing PRP v1/v2 numeric fields. The affected contracts
+include command/event envelopes, hello/reconciliation, acknowledgements, warm
+transitions, raw-to-normalized delivery cursors, database uniqueness and paging,
+native receipts, and public history cursors. A peer lacking the capability stays
+on its declared legacy contract; it is not advertised as unlimited.
+
+For each delivery lane, the transition is:
+
+1. Before the ordinal ceiling, the sender stops admitting new lane entries and
+   persists a rotation intent with old epoch, final ordinal, successor epoch and
+   transition ID. Admission leaves reserved control capacity for this step.
+2. Existing admitted entries drain durably through the final ordinal. Work that
+   is still executing retains its semantic call ID and input receipt; it does
+   not need to finish merely to rotate a transport counter.
+3. The receiver verifies its contiguous committed cursor and commits the old
+   epoch's close receipt plus the successor head in one transaction. It returns
+   the exact transition receipt. This operation is idempotent by transition ID
+   and rejects conflicting successors.
+4. The sender verifies the receipt, commits its successor head, and admits new
+   entries at ordinal one. Their run, turn and provider identities are unchanged.
+   Results for older calls still reference their original semantic identity.
+
+A crash at any step reopens the persisted transition. Lost replies repeat the
+same transition, never allocate a competing successor. An old frame is resolved
+against its old receipt and cannot be reinterpreted as a fresh ordinal in the
+new epoch. Neither peer may infer rotation from a low incoming number. Cursor
+rotation does not invoke turn completion, interrupt, resume or provider restart.
+
+Current-state revisions use an exact opaque compare-and-swap identity. If the
+implementation retains a bounded revision ordinal, rotating its revision epoch
+is atomic with the new state and its commit receipt. A stale revision can never
+become valid again after wraparound. Revision identity is not an ordering API.
+Native provider generations preserve legacy numeric increments until their safe
+namespace is exhausted, then switch permanently to opaque identities bound to
+the exact launch transition. PostgreSQL session-goal mutations use opaque
+equality tokens with exact retry evidence. The retained numeric goal revision
+freezes at activation, and a pre-transition numeric expectation cannot match
+after token activation. Goal source epochs and cursors remain separate from
+this compare-and-swap identity.
+
+Controller recovery ownership already uses a fresh random lease identity,
+checked together with the controller identity. Its retained integer generation
+is diagnostic and saturates at the database integer limit; it is never a sole
+ownership fence. Reaching that value cannot block a new claim or revive a stale
+lease.
+
+The command lane now negotiates `transport.command_epochs.v1`. The controller
+holds new command admission after 1,048,576 entries, drains accepted commands,
+and publishes an exact transition. The native runner commits that receipt and
+its successor head together. Semantic calls and an active provider turn remain
+live. An optional lower test threshold forces repeated rotations. Each side
+keeps only its current head/transition and resolves older receipts by identity;
+new ordinals use the `controllerEpoch` namespace. PostgreSQL's sequence index
+includes it. Admission can persist a transition during reconnect once the
+capability has been authenticated; it does not require a live socket to preserve
+that intent. Unnegotiated peers cannot inherit that namespace.
+
+The raw event lane now negotiates `transport.event_epochs.v1` on PRP v2.
+Its authenticated challenge binds the exact sender resume cursor and rotation
+limit. The runner persists its intent, pauses event admission, drains the old
+outbox, and installs the next `sourceEpoch` only after the controller's atomic
+close/head receipt. Old ACKs resolve their exact closed namespace; they cannot
+advance the new head. A committed receiver with a lost reply admits only the
+matching pending sender intent. Commands, lease renewal and pending provider
+work retain their identities through this exchange.
+
+Raw history paging selects one indexed namespace. The normalized reader follows
+one exact successor only after consuming the previous final frame, then commits
+an explicit zero cursor for that successor. It never compares ordinals across
+namespaces or loads the historical chain. Current proof slots preserve their
+bounded chronological order separately from history ordinals. Warm attachment
+receipts bind the old source namespace and keep the native indexed store live.
+These changes rotate raw PRP delivery independently of normalized output and
+the public run-log cursor.
+
+Normalized delivery checkpoint revisions and provider outbox entry identities
+are also equality-only identities. New effect receipts have no ordering counter.
+Encrypted connections re-authenticate with new keys before their nonce counters
+reach a bound, preserving the durable delivery cursors and active provider.
+The indexed normalized outbox advertises a separate epoch limit. Its producer
+atomically commits a close receipt, successor head, reducer snapshot and first
+successor event before publishing that event. The first event carries the exact
+`sourceEpochTransition`; the database verifies the old contiguous prefix and
+absence of an accepted tail beyond it, then atomically installs the successor.
+The bounded outbox may contain both namespaces. ACKs remove only the exact next
+pending event. Lost ACKs replay the same event and transition. This local durable
+outbox variant does not need another network handshake: its first-event receipt
+is the receiver's acknowledgement boundary. It never rotates the raw cursor or
+provider session.
+
+Recovery checkpoints encode an epoch with its local ordinal. Historical paging
+follows an exact successor only at the preceding final ordinal. Body catalogs
+use byte offsets within one bounded provider frame, so a body can cross event
+namespaces and repeated identical bodies share their chunk references. Goal
+projection tracks source epochs separately from run ownership. The alternate
+native coordinator now accepts epoch-bearing normalized input while preserving
+payload hashes and settlement-anchored ordering.
+
+Public run-event history has opaque row IDs, an `event_epoch`, and bounded
+epoch-local `seq` values. API cursors use `e:<epoch>:<seq>` for new epochs;
+safe legacy numeric IDs retain their API number representation; larger retained
+IDs remain exact decimal strings. Indexed epoch heads and
+semantic-lane links support ordered paging without treating `seq` as globally
+ordered. Browser event history retains a bounded tail, shows when earlier rows
+were collapsed, and treats websocket event notifications as wake hints; durable
+polling supplies the rows. Run-log chunks use exact decimal byte-start cursors
+as identity and ordering, while `seq` remains legacy diagnostic data. The UI
+keeps a bounded recent output window and identifies both retention collapse and
+a segmented tail that starts after earlier bytes.
+
+Tiny qualification thresholds exercise repeated rotation with an active turn,
+pending semantic calls, replay from the earliest epoch, reconnect, and a process
+kill at each transition boundary. Tests must include JavaScript's safe-integer
+boundary and database integer boundaries without generating that many records.
+
+## Recovery captures one consistent set of stores
+
+Provider history pagination and provider model-context recovery are separate
+requirements. Paperclip requests metadata-only Codex reads/resumes and uses its
+indexed reducer to recover delivery. If an active turn settles during a metadata
+read, Paperclip checks at most four recent pages and rereads the current status;
+it does not search the completed history for an active turn that has disappeared.
+An inconsistent active status retains the recovery hold.
+
+A fresh-thread probe of installed Codex 0.153.4 reports `historyMode: paginated`.
+Indexed Codex startup now explicitly requests that mode for new threads and
+verifies it on both start and resume. Missing or legacy mode is rejected before
+turn admission, without creating a replacement provider session. Legacy
+Paperclip sessions retain their provider's history contract.
+
+Paginated mode does not establish bounded cold recovery. In that release, the provider's
+[model-context loader](https://github.com/openai/codex/blob/rust-v0.153.4/codex-rs/thread-store/src/local/model_context.rs)
+scans backwards to a suitable replacement-history checkpoint. Without one, it
+can accumulate the complete replay; legacy rollouts use the full-history path.
+`excludeTurns` bounds the API response, not that internal work. Qualification must
+therefore measure cold provider recovery as well as Paperclip continuation and
+require a supported, bounded current-context checkpoint. Paperclip must not edit
+provider journals or replace action receipts with an AI summary to simulate this
+capability. The installed provider's cold-recovery guarantee remains unqualified.
+
+Upstream Codex 0.159.0 includes
+[the newer compaction-boundary recovery implementation](https://github.com/openai/codex/commit/e7bbc79f482acf285e50a09a9f898aeb2ce3881c).
+It persists companion resume metadata and stops at the latest complete
+replacement-history checkpoint, including mid-turn compaction. This is the
+candidate provider for qualification; the 0.153.4 finding must not be generalized
+to that newer release. Missing/incomplete checkpoints still use full replay.
+Using the newer release does not by itself qualify incremental persistence,
+containment, or whole-session source-loss restoration.
+
+In stock 0.159.0, the SQLite history projection is another recovery path:
+`thread_history_materialization.rs` reads the entire unprojected suffix into
+memory. Healthy indexed resume and rebuilding a missing/lagged projection
+therefore have different costs. The real complete-package browser continuation
+test passes, but cannot establish a bound for that missing-index case.
+Its app-server protocol has paged history reads and forking, but no immutable
+same-session checkpoint/pinning API. A fork changes provider identity and is
+not a substitute for that contract. Completing this provider portion requires
+provider changes or a qualified persistence implementation underneath it.
+
+A recoverable session consists of controller authority, both native stores,
+referenced payloads, provider persistence, and exact process ownership. A native
+snapshot or a PostgreSQL dump on its own is only a component. The backup becomes
+usable only when one durable recovery manifest binds all required components.
+
+The manifest is a bounded root record, not an array of every historical file.
+It contains the company/session/run binding, format and capability versions,
+source store identities, current revisions/digests, committed delivery boundary,
+provider checkpoint identity, containment identity and an indexed inventory
+root. Inventory pages and immutable objects are content verified and independently
+addressable. Credentials are freshly provisioned on restore; backup data does
+not grant a new process execution authority.
+
+The coordinator has durable states `requested`, `boundary_held`, `copying`,
+`verified`, `published` and `released`. Each transition is fenced by the same
+maintenance owner, and every copy cursor is resumable. Lost leases cancel owned
+workers and wait for their exit before relinquishing local fences. Repeating a
+job uses the same request and source revisions; it cannot silently take a newer
+snapshot under the old job identity.
+
+At the boundary:
+
+1. Hold new admission for the exact session and establish a recoverable provider
+   checkpoint through its supported protocol. An ambiguous active provider is
+   held for reconciliation; an empty event queue does not establish quiescence.
+2. Establish ownership of both native stores and capture their exact current
+   revisions, outbox and receipt roots. Do not copy live SQLite/WAL files as
+   ordinary directory contents.
+3. Under the controller's write fence, capture the matching authority and raw /
+   normalized delivery boundary using one exported PostgreSQL snapshot. The
+   exporter and every inventory query use that snapshot, not unrelated queries
+   from different transactions. Expired snapshots fail the job.
+4. Pin the immutable native/provider generations and payload roots. Once these
+   pins and the boundary record are durable, execution can release the boundary
+   and continue against newer generations. Copying old bytes is background work.
+
+Publishing requires that each component's identity, size and digest match its
+inventory, all references are present, and replay relationships between the
+controller and native cursors are valid. There may be unacknowledged data at the
+boundary, but it must have an exact durable source and idempotent destination.
+There may not be a controller cursor beyond durable source data or an accepted
+effect with no recoverable receipt. The manifest is published atomically last.
+
+Repeated checkpoints upload changed immutable generations, newly closed
+segments and a bounded current tail. They do not rehash, recopy or enumerate all
+historical provider files on each turn. A provider without a checkpoint/pinning
+or incremental persistence interface cannot satisfy this foreground guarantee;
+its remote activation remains unqualified until that gap is addressed. The
+existing full directory/native copy is a maintenance backup, not evidence of
+incremental online checkpointing.
+
+Restore creates a new owned destination, verifies the manifest and current
+roots, imports the bound controller state, and restores the matching native and
+provider checkpoint. Required current/pending objects are verified before
+execution. Historical immutable partitions can be restored lazily behind their
+verified index, so an unavailable unrelated old body does not prevent current
+work. A requested missing/corrupt old receipt is an integrity failure for that
+lookup, never permission to repeat the action. Restore cannot synthesize a new
+session because one component is missing.
+
+Qualification removes every source volume after publishing, restores solely
+from the backup, resumes the same provider identity and reads an early receipt
+and output through the browser. It repeats after each copy/publication crash,
+concurrent writes, stale ownership, corrupt/missing objects and expired database
+snapshots. A component-only source-loss test cannot stand in for this test.
+
+## Process ownership and retirement
+
+A controller incarnation UUID is not an operating-system boot identity. PID,
+process start time, process group and parent death are useful observations, but
+they cannot prove that a descendant which called `setsid` has stopped.
+
+For automatic recovery after an ambiguous runner/provider crash, the execution
+boundary must enforce containment before the first provider child runs. The
+qualified Linux implementation may use a protected cgroup v2 subtree or an
+equivalently isolated container. It records host/engine identity, OS boot
+identity, immutable containment identity, launch identity and owner in durable
+intent before admitting effects. The provider cannot write the parent cgroup,
+escape through a host runtime socket, join host PID namespaces or acquire the
+privileges needed to move outside that boundary.
+
+Retirement fences new launches, requests termination of the entire boundary,
+and observes the boundary empty under the same host/boot/containment binding.
+For cgroup v2, the check covers descendants (`cgroup.events: populated 0`), not
+just the direct child's wait status); see the [kernel containment contract](https://docs.kernel.org/admin-guide/cgroup-v2.html). An authenticated remote provider needs an
+equivalent qualified destruction receipt for its immutable sandbox identity.
+Only after this proof commits may unresolved owner rows move to historical
+receipts and replacement admission proceed. Recycled PIDs, missing metadata,
+unreachable hosts and ambiguous destroy responses retain the ownership hold.
+
+Ordinary macOS processes can continue from a successfully committed suspension
+through the existing runner protocol. That fact must not be rejected merely
+because the checkpoint uses indexed storage. It also must not be repurposed as
+permission for destructive maintenance or uncertain crash recovery. Until an
+enforced boundary is available, those ambiguous operations remain held. The
+product must state which guarantee the selected execution environment provides.
+
+Controller reattachment to the exact surviving local runner validates current
+authority and then authenticates that runner's transport. It does not enumerate
+historical unresolved process owners: no provider replacement or retirement is
+authorized by that claim. Dead-runner admission checks for any unresolved owner
+through one indexed existence query. Its presence holds replacement even when
+the recorded PID and process group have disappeared; an escaped descendant may
+still be alive. This check does not enumerate earlier launches. A qualified
+retirement path must still close those owners before automatic replacement can
+be enabled. Bounded admission alone does not provide that retirement mechanism.
+
+Containment qualification includes double-forked and `setsid` descendants,
+controller/runner kills, host reboot identity changes, reused PIDs, inaccessible
+containment metadata and an attempted escape. The replacement provider starts
+only after the exact prior boundary's retirement commits.
+
+## Migration and retained sessions
+
+Retained legacy journals are migrated once under explicit maintenance admission.
+Migration may take time proportional to legacy history, but streams with bounded
+memory and checkpoints its progress. It does not happen as an invisible full
+scan on every continuation. The old state stays authoritative until controller,
+runner and provider stores are all staged, validated and published by one
+activation record. A crash retries that activation rather than mixing formats.
+
+Production admission requires exact stopped/contained ownership, a renewable
+maintenance lease, no competing writer and the original session binding. It
+cannot be supplied by an always-successful callback, expired lease, dead PID
+or missing file. Every database commit and filesystem publication rechecks its
+fence. A lost lease preserves staged data for a later authorized owner.
+
+## Capacity, retention and collection
+
+The implementation reserves a bounded control/settlement lane independently
+of bulk output. It obtains storage and queue credits before admitting new work
+whose results must be persisted. Pressure stops new admission, drains what can
+settle, and keeps interrupt, heartbeat and ownership signals available. It does
+not silently truncate a receipt or acknowledge data that exists only in memory.
+
+A storage rejection is retryable through the same owner only when a fresh read
+proves the exact pre-write revision and bytes are still authoritative. Lost
+commit replies and unreadable storage are indeterminate. They require exact
+commit-receipt reconciliation, never an assumed rollback. Provider result
+delivery similarly persists intent before sending and retains uncertainty when
+its acknowledgement is lost.
+
+History retention, replay correctness and backup retention are separate.
+Garbage collection is paged background work rooted in current authority,
+unacknowledged delivery, live receipt references and published/pending backup
+pins. An object uploaded before a failed metadata transaction is an orphan
+candidate only after the publication grace period and a fenced root check.
+Concurrent writers can publish new references or pins; an old mark pass cannot
+delete those objects. Deletion records are resumable and idempotent, and no
+collection step scans every historical object on an execution path.
+
+Receipt deletion requires an explicit protocol horizon proving that the same
+logical identity can never be admitted again. Without such a horizon, exact
+receipts remain. A summary, Bloom filter, age cutoff or cache eviction is not a
+receipt-deletion authorization.
+
+## Qualification and activation
+
+Activation is per persisted session and negotiated capability, with an explicit
+matrix for provider, host environment, fresh/retained state and recovery mode.
+Enabling one cell never implies qualification of another. Budgets, approvals,
+company boundaries and operator retention remain enforced throughout.
+
+The final candidate needs all of the following evidence on identified source
+and artifacts:
+
+- History growth across former limits, large individual streamed outputs, many
+  sequential calls in one active turn, and many continuations; measure bounded
+  current bytes, foreground read/write bytes, queue sizes and latency.
+- Tiny partition, segment and cursor-epoch thresholds with old exact replay,
+  concurrent relocation and fault injection at each durable cutover.
+- Real storage exhaustion and restored capacity for database, local/native
+  storage, provider persistence and object storage; lost replies, read-only
+  storage and corruption remain distinct from a confirmed rollback.
+- Whole-session backup/source loss/restore and process-tree retirement through
+  the production admission path, including retained-session migration.
+- Browser → Paperclip → native runner → actual provider continuation, controller
+  restart during output, runner/provider crash cases, and the declared elapsed
+  endurance period. A short or accelerated test does not satisfy a 72-hour gate.
+- A green coherent full repository check, plus focused provider and protocol
+  suites. Earlier failed attempts and unqualified environments stay visible.
+
+The execution guarantee is enabled only for cells whose required evidence is
+complete. The implementation record identifies outstanding cells and component
+results; it must never turn a successful storage microbenchmark into a claim
+that the entire recovery system is finished.

+# Long-running agents without history limits
+
+- Date: 2026-09-28
+- Status: Target contract; indexed local Codex implementation in qualification, disabled for fresh sessions by default
+- Scope: Paperclip native runner, controller persistence, continuation, recovery, and historical output
+- Baseline: PR [#14312](https://github.com/paperclipai/paperclip/pull/14312), commit `e6bed1231ae286698d440fdfec4d19ce3362af42`
+- Full lifetime contract: [state machines and activation requirements](../architecture/runner-history-lifetime.md)
+- Related contracts: [runner architecture](../architecture/paperclip-runner.md), [compatibility](../architecture/paperclip-runner-compatibility.md), [database](../DATABASE.md#native-runner-persistence), [execution semantics](../execution-semantics.md)
+
+**Current status, 2026-09-29:** the scalable Paperclip storage path is implemented
+and remains opt-in. The latest native candidate passed its release suite and a
+10 GiB receipt-growth test; the same native implementation also passed the
+actual local Codex browser workflow, including active controller restart.
+These are identified component/workflow measurements, not a full
+unlimited-history qualification. Stock
+Codex recovery/checkpoint interfaces, whole-session source-loss restoration,
+enforced process containment and retained-session migration admission remain
+open. The elapsed 72-hour requirement has not passed. Sections 59–64 record the
+latest evidence; earlier measurements below retain their original scope.
+
+**Product decision, 2026-09-29:** use stock Codex. Do not create or maintain a
+Paperclip-specific Codex build. Keep provider replay/checkpoint limitations
+explicit and keep the full lifetime contract unqualified while they remain.
+
+## 1. Product requirement
+
+An agent may work continuously for days, perform arbitrarily many sequential
+operations, generate arbitrarily much historical output, and continue through
+review turns. Accumulated work must not make its next operation or continuation
+fail. A single long active turn is included; resetting history at turn boundaries
+is insufficient.
+
+There is no application-defined lifetime ceiling on journal bytes, completed
+commands, completed tool calls, events, or review turns. Increasing storage
+capacity must not require restarting the agent, changing its provider session,
+or abandoning its task. Storage rotation is an internal operation, not a new
+model turn or a request for the user to start over.
+
+"Unlimited" means no cumulative application limit. Storage, network throughput,
+and provider capacity still have physical limits. Explicit company budgets,
+approvals, operator timeouts, retention policies, and provider restrictions still
+apply. Finite limits on a message, concurrent operations, memory, and pending
+delivery protect the service; completed work releases that capacity. Physical
+storage exhaustion produces a recoverable resource condition, not an identity
+mismatch or a corrupt-session classification.
+
+## 2. The design in plain language
+
+Keep three separate records:
+
+1. **Current state:** which agent/session owns the work, where delivery has
+   reached, what is unfinished, and whether completion was accepted. Read this
+   to resume. Its size depends on current work, not the age of the task.
+2. **History:** the events and output that people can inspect. Add records and
+   read them in pages. Old output is never a prerequisite for ordinary resume.
+3. **Action receipts:** exact identities and outcomes of previously handled
+   commands and tool calls. Look up one receipt when a request is repeated;
+   never load every past receipt into memory.
+
+The existing "proof" becomes a typed view of current state and a few referenced
+receipts. It is maintained as work happens. It is not reconstructed by searching
+all historical output, and it is never an AI-generated summary.
+
+```mermaid

+
+## 3. Problems the implementation must eliminate
+
+The reviewed PR makes large existing files readable with bounded worker memory.
+It does not establish the product requirement above.
+
+| Current mechanism | Consequence | Required replacement |
+| --- | --- | --- |
+| 192 MiB controller journal read limit | A sufficiently large valid history is unreadable | No aggregate journal file in the execution path |
+| 8 MiB reconstructed evidence budget | Retained authority can exceed the reader budget | Typed current state plus bounded/paged active references |
+| Full JSON scan/hash for identity and evidence | Continuation time grows with historical bytes | Indexed current-state read and generation verification |
+| `DurableCoreStore.save()` rewrites and fsyncs all state | Each event can rewrite previous output and block the controller | Incremental durable transactions off the API event loop |
+| 500 retained controller commands | A long run eventually cannot enqueue another command | Separate pending commands and disk-backed historical receipts |
+| 4,096 controller event window | Historical authority can fall out of the window | Explicit current authority independent of event retention |
+| Provider bridge receipt/identity ceilings | Active turns can be interrupted solely for accumulated receipts | Exact indexed receipts with no lifetime count/byte cap |
+| Runner/provider JSON contains arrays and maps | Restore/save work grows with retained state | Transactional rows, paged outbox, and bounded caches |
+
+The provider bridge currently has separate limits for 4,096 durable call
+receipts, 65,536 settled call IDs, and retained result bytes. Removing only the
+controller's JSON file does not solve these limits. Conversely, outbox limits
+and maximum simultaneous pending calls are flow control and should remain.
+
+The review reproduced a writer/read mismatch: loading a valid 191.6 MiB journal,
+then enqueueing an 800 KiB command, produced a 192.4 MiB journal that the writer
+could no longer reopen. The compatibility fix must not claim that all
+writer-admitted histories are supported until this is addressed.
+
+## 4. Storage decisions
+
+### Controller: use the existing Postgres authority
+
+Postgres already commits native events before the controller acknowledges them.
+Extend that transaction to maintain current transport state, action receipts,
+and recovery evidence. Do not introduce another authoritative controller
+database that must be coordinated with Postgres for every event.
+
+Replace `control-plane-state.json` as the v2 execution authority. A small local
+locator may identify the store and format; it grants no execution authority.
+The controller keeps a bounded cache of current rows. No API exposes the full
+historical store as an in-memory `state` object.
+
+Here, v2 means the new durable-store format, not the already existing PRP wire
+version 2. Negotiate a separate versioned durability capability (proposed name:
+`durability.indexed_state.v1`) and explicit payload/reference schemas. Never
+change existing PRP message meaning merely because both peers speak PRP v2.
+
+Preserve the runner package's dependency boundary: define an asynchronous
+`DurableAuthorityStore` port in the package and implement the production
+Postgres adapter in `server/`. Standalone/evaluation controllers use a qualified
+SQLite implementation of that port without requiring a Paperclip server or
+Postgres installation. A standalone fixture must supply its own real durable
+event/effect commit boundary; it cannot acknowledge a mocked business commit.
+Open stores asynchronously before accepting connections. Await every durable
+mutation through transport and lifecycle callers; constructors and public
+getters must not conceal blocking I/O or fire-and-forget persistence.
+
+Proposed logical tables, finalized with the schema implementation:
+
+| Table | Contents and primary access |
+| --- | --- |
+| `native_session_authorities` | Company/session/runner/environment binding, current run and authority epoch, controller fencing token, generation, delivery cursors, current lifecycle, transition reference. Point lookup by bound session. |
+| `native_pending_commands` | Only commands that still need delivery or settlement; stable ID, sequence, input digest, payload reference, phase. Bounded by admission credits. |
+| `native_command_receipts` | Exact completed command identity, canonical input digest, disposition, result/reference, original sequence and authority epoch. Unique scoped command ID; indexed sequence lookup. |
+| `native_effect_receipts` | Semantic call identity, input digest, durable intent, application receipt, result/reference, and delivery state. Unique scoped call ID. Never infer completion from missing history. |
+| `native_process_owners` | Live or not-yet-proven-stopped process owners, with host/sandbox identity, boot identity/start time, and stop evidence. Settled owner history is separate. |
+| `native_run_evidence` | Validated completion/finish reference, terminal state, current provider binding, unresolved counts, and sticky bootstrap/effect facts. Updated with the facts it summarizes. |
+
+Reuse `heartbeat_run_events`, native results/finalization tables, and existing
+semantic-operation receipts rather than duplicating their business authority.
+The proposed transport receipts reference those records. All new keys and
+foreign keys enforce company/run/session consistency, not just globally unique
+IDs. Actor authorization and mutation audit records remain in existing services.
+Bootstrap/lease credentials remain access-controlled and use the existing
+secret-storage rules; snapshots, historical output, and proof exports must not
+expose plaintext credentials. Persist only necessary authentication material,
+with explicit revocation and expiry independent of history retention.
+
+Receipt storage is indexed on disk and may grow. Do not hide another lifetime
+cap in a JSON column, an in-memory map, a checkpoint attachment, or a manifest.
+Partitioning is storage administration behind stable receipt keys. A partition
+locator must itself be indexed; a lookup cannot search every historical
+partition. Do not time-partition an idempotency table in a way that permits the
+same logical key to be accepted twice.
+
+### Runner: transactional local state and receipt index
+
+Use an embedded SQLite store for runner-owned state, pending events, command
+receipts, and provider tool receipts. Keep it on the runner's durable local
+volume, including inside a remote sandbox. The runner does not need direct
+Postgres credentials. Controller and runner never concurrently mount the same
+SQLite database over a network filesystem.
+
+The initial engine policy is WAL mode with `synchronous=FULL`, short
+transactions, bounded page caches, and a dedicated storage executor. Persist
+before acknowledging or releasing an effect. Schedule checkpoints by WAL bytes
+and elapsed time; cap reader transaction lifetimes so readers cannot pin an
+ever-growing WAL. If checkpointing falls behind, apply admission backpressure
+while preserving a reserved control/settlement lane. SQLite's WAL is not the
+user's audit history and is not retained indefinitely.
+
+All reads/writes in TypeScript run in a worker; Rust uses a dedicated storage
+thread. The protocol/heartbeat loop must not serialize history or wait on a
+synchronous filesystem call in its event loop. Binding choice and binary
+packaging need a qualification spike, not a new hand-written transaction engine.
+Pin and verify a SQLite build with the WAL-reset fix (3.51.3 or later, or a
+documented fixed backport). A Node minimum version alone does not prove its
+bundled SQLite is qualified.
+
+SQLite and filesystems have finite per-file limits. Large historical bodies
+live outside this database. The receipt-store interface supports online
+partition relocation/splitting with stable logical keys before backend file
+limits, without changing provider/session identity. Splits copy in bounded
+batches, capture concurrent writes, verify them, then atomically switch the
+authoritative locator; old readers retain the prior generation until drained.
+Publish partition generations through the active store. A write admitted under
+an old generation is fenced before cutover or captured in the migration delta;
+it cannot succeed only in an abandoned shard. An indeterminate cutover holds
+the affected key range for reconciliation rather than treating an empty lookup
+in the new shard as a new command. No correctness step relies on an atomic
+transaction across multiple SQLite WAL databases.
+An arbitrary raised SQLite size limit is not the implementation of unlimited
+history. Partition routing and crash-safe relocation belong in storage
+qualification, including a test with deliberately tiny partition thresholds.
+
+### History and large bodies
+
+Keep the existing company-scoped run-log API as the user-facing history
+contract. Use indexed cursor pagination. Move large bodies to the existing
+local/object-storage abstraction and return authorized references through that
+API; update shared types, server resolution, and UI consumers together.
+
+Store immutable, independently verifiable chunks/segments (initial target:
+32 MiB). Segment size is a rotation threshold, not a total-history limit.
+Neither the current-state row nor a startup manifest contains an array of every
+segment. Segment metadata and content references are indexed and paginated.
+Reads fetch the requested range with at most a fixed-size segment verification
+on a cache miss. Streaming upload/download/export cannot
+assemble the complete object in memory or one `JSON.stringify` call.
+
+A referenced body is durable before the metadata transaction commits. Orphan
+bodies from failed transactions can be garbage-collected after a grace period;
+metadata must never point to bytes that have not been committed. Local mode
+uses private temporary files, sync, rename, and directory sync. Remote mode
+requires a completed upload and verified size/digest before publication.
+
+Content references include company/store scope, object identity, byte length,
+digest, and media/schema type. They are not arbitrary paths or capability URLs.
+New transport chunk/reference support is negotiated. Large historical output
+does not imply arbitrarily large individual PRP frames; enforce existing frame
+limits and stream or externalize oversized content without silently truncating
+authority-bearing inputs/results.
+
+## 5. Current evidence replaces history scanning
+
+Maintain these facts when validating the event/command that establishes them:
+
+- Exact company, issue, run, normalized session, runner, environment lease,
+  provider/account, and authority epoch binding.
+- Controller ownership/fencing token and monotonic state generation.
+- Next command/event sequence and durable contiguous acknowledgment cursors.
+- Pending commands, unacknowledged events, unresolved semantic effects, active
+  provider turn, pending terminal delivery, and pending warm transition.
+- Live/unresolved process owners, including provider and sidecar processes.
+- Validated completion contract and accepted finish/result/receipt references.
+- Sticky facts such as `providerEverStarted` and `externalEffectEverAdmitted`.
+  An empty current queue does not establish that nothing ever happened.
+
+Do not retain every former process as active authority forever. A process owner
+leaves the active set only after exact stop evidence is persisted. PID alone is
+insufficient; bind host/sandbox, boot identity, start identity, and process group
+as appropriate. Failure to establish death preserves the unresolved owner and
+prevents unsafe replacement. Resource limits cannot silently discard it.
+
+Completion is materialized from validated structured finish input and the
+server's accepted result, not from a last-event heuristic. Inputs/results that
+need exact comparison use immutable references and canonical digests. Collections
+of evidence are paged relations, not growing arrays inside a proof object.
+
+Expose purpose-specific operations, for example:
+
+```ts
+readAuthority(binding): Promise<AuthoritySnapshot>
+readContinuationState(binding, expectedGeneration): Promise<ContinuationState>
+readCleanupOwners(binding, cursor): Promise<Page<ProcessOwner>>
+getCommandReceipt(binding, commandId): Promise<CommandReceipt | null>
+getEffectReceipt(binding, callId): Promise<EffectReceipt | null>
+readPendingEvents(binding, after, byteBudget): Promise<EventPage>
+```
+
+There is deliberately no `readWholeJournal()` or history-sized `proof` return.
+Cleanup can require all unresolved owners, but those are admitted live work,
+not every process ever recorded. Read pages under a consistent generation and
+recheck the owner fence/generation before the action.
+
+## 6. Commit, acknowledgment, and replay rules
+
+### Runner event delivery
+
+1. Runner transaction commits the event, its identity/digest, updated state,
+   and any provider-event receipt. Only then may it send the event.
+2. Controller transaction validates identity and sequence, commits the raw
+   inbox record/reference with current transport state, and advances its
+   contiguous accepted cursor. Exact duplicates return the existing outcome;
+   conflicting identities or gaps fail closed.
+3. Only after that commit does it acknowledge the runner. This ACK proves raw
+   inbox durability, not normalized run-log consumption. The driver commits
+   each short reducer step, its raw position (epoch, frame, expansion ordinal),
+   and its pending normalized events together before publishing those events.
+   The run-log writer accepts their exact identities and bytes before the
+   consumer removes them from the pending outbox. Interrupted delivery replays
+   the original timestamp and sequence. A completed-frame marker prevents an
+   epoch transition in the middle of one raw frame's expansion.
+4. Runner commits the acknowledgment before freeing the corresponding outbox
+   payload. A lost acknowledgment causes a safe duplicate delivery.
+
+Keep server-side replay validation indexed even after old payloads are archived.
+Do not compare only a high-water mark and silently accept conflicting old data.
+If retention removes historical payloads, retain the exact ID/digest and
+receipt needed for any still-valid replay namespace.
+
+### Commands and semantic effects
+
+Persist an accepted command before transmission. Persist a tool-call intent
+with its exact idempotency key before invoking the existing business operation.
+Persist the resulting receipt before returning success or delivering the result
+to the provider. Update the pending set and current evidence in the same local
+transaction as that durable outcome.
+
+Across Postgres, a runner database, and an external application there is no
+single atomic transaction. Use the existing business idempotency ledger and
+explicit pending/settled/delivery phases. On a crash after an external effect
+but before its receipt, query/reconcile using that same key. Where a provider
+cannot establish the outcome, retain an indeterminate effect and require the
+existing recovery decision. Never re-execute an uncertain operation because a
+local receipt or historical payload is absent. This design does not claim
+exactly-once execution for arbitrary external systems.
+
+Command and provider-call keys include their authenticated namespace. Store
+the original bounded identity and canonical input digest; a hash index alone
+is not permission to conflate different IDs. Exact retries return the prior
+outcome, conflicting reuse is rejected, and cache misses consult durable
+storage. No Bloom filter, FIFO eviction, or rolling summary may decide that an
+old call is safe to execute again.
+
+Acknowledged event payloads may be reclaimed. Receipts remain while their
+namespace can replay. Retiring a namespace requires a durable fence accepted by
+both peers; stale messages are then rejected without execution. A provider's
+arbitrary call IDs cannot be retired by inventing a turn boundary it does not
+guarantee. Keep their exact on-disk receipts as long as necessary. Normal
+storage maintenance must not force a provider-process restart to clear them.
+
+## 7. Resume, restart, cleanup, and integrity
+
+Normal continuation reads the authority/evidence rows and pending records,
+then verifies the live runner or retained provider checkpoint using the current
+ownership rules. Reconnect replays only the unacknowledged delivery range.
+Crash recovery opens the transactional store and reconciles pending phases;
+it does not replay the lifetime history to rebuild current state.
+
+Warm transition keeps the existing prepare/activate/acknowledge semantics and
+durable old/new identity binding. Persist every phase and the exact receipt.
+Epoch rotation changes current authority; it does not erase historical receipts
+or become necessary merely because a file or command counter filled up.
+
+Replace byte-exact hashes of entire growing journals with a versioned digest
+of the bounded authority snapshot, generation, cursors, active references, and
+transition receipt. These digests detect changes; they are not authentication.
+Trust comes from server-owned transactions, authenticated PRP bindings, protected
+runner storage, and independently verified process ownership. An agent-written
+checkpoint claiming "safe" never grants permission to resume or kill a process.
+
+Validate data and update evidence at ingestion. On normal resume, validate the
+current snapshot and referenced active records. A separate, resumable audit can
+verify historical segments; it must not gate every new turn. Corruption of an
+unreferenced archived output is a history-availability problem. Corruption or
+absence of current authority, an unresolved effect, or a necessary checkpoint
+blocks the corresponding operation with a specific reason.
+
+Readers take short consistent snapshots. Before a destructive action, acquire
+the appropriate ownership lease and compare the expected generation/fence in a
+transaction. Do not hold a database read transaction open across remote process
+inspection. Revalidate remote boot/start identity immediately before signaling.
+
+## 8. Backpressure and capacity
+
+No unbounded memory queue is introduced. Bound concurrent calls, unsent commands,
+unacknowledged bytes, worker jobs, transaction size, record size, and open readers.
+Reserve capacity for interruption, completion, acknowledgment, and cleanup.
+Credits return as work settles. Group commit is allowed only when all callers
+wait for durability before acknowledgment or effect release.
+
+If the controller or storage cannot keep up, stop admitting new work and drain
+what is already admitted. If provider output cannot be paused safely, use its
+qualified interrupt/checkpoint path and retain ownership/evidence. Report
+`storage_pressure`, `delivery_backpressure`, `storage_unavailable`, or an exact
+provider limitation; do not report an identity mismatch. Once capacity returns,
+resume through the existing owner with the same keys and cursors.
+
+Archive acknowledged history continuously; do not wait for the agent to finish
+or for a maintenance scan of its entire history. Local and hosted deployments
+can add storage or relocate partitions behind stable references. If configured
+retention deletes history, it must not remove active payloads, replay receipts,
+or current authority. Audit retention and execution correctness are separate
+contracts, both company-scoped.
+
+Lease renewal and idle timeout remain distinct from active execution duration.
+Long-running mode must not impose a hidden wall-clock cutoff through transport
+defaults, sandbox TTL, or provider configuration. Audit and test those policies;
+honor explicit operator limits and surface nonrenewable provider limits. Storage
+work cannot bypass budgets, holds, approvals, or single-assignee ownership.
+
+## 9. Performance contract
+
+Let H be total historical bytes, R completed receipts, A admitted active work,
+and D newly written/read bytes. With A held constant:
+
+| Operation | Required cost |
+| --- | --- |
+| Accept an event/result | Work proportional to D plus indexed updates; never rewrite H |
+| Resume current authority | Bounded current rows/active pages plus index access; never scan H or R |
+| Retry an old command/call | Exact indexed lookup, generally O(log R), plus that result's bytes |
+| Restart | Bounded WAL recovery plus current/pending state; not lifetime event replay |
+| Inspect history | Requested page/range plus fixed-size segment verification on a cache miss; never scan H |
+| Archive/compact | Incremental bounded batches, resumable off the execution path |
+
+Do not promise mathematically constant latency regardless of database size,
+cache state, or storage hardware. Require no linear dependence on lifetime
+history, bounded memory, and bounded foreground work. A large unacknowledged
+backlog can take time to deliver; it is live work, not an excuse to scan already
+acknowledged history. Current-state reads have priority over archive work and
+fair scheduling across companies so one busy agent cannot occupy every worker.
+
+Sequence/cursor values must not silently overflow JavaScript safe integers.
+Use exact database/Rust integers and decimal-string or negotiated exact wire
+representations. Any protocol epoch rollover is transparent storage/protocol
+maintenance and must not terminate the provider turn.
+
+## 10. Migration and rollout
+
+1. **Keep the immediate reader fix scoped.** PR #14312 remains a legacy
+   compatibility improvement. Fix/reproduce the aggregate writer/read mismatch
+   explicitly; do not remove every size guard and call that unlimited support.
+2. **Introduce the store interfaces and v2 schemas.** Add Postgres migrations,
+   typed evidence, the runner store, and golden cross-language contracts.
+   Negotiate the new durability capability and persist the selected format on
+   the session. Old peers stay on the legacy path with visible limits.
+3. **Populate evidence alongside legacy writes in shadow mode.** Compare all
+   admission/cleanup/recovery decisions with legacy classifiers. Legacy remains
+   authoritative; any disagreement is a release failure. Shadow mode does not
+   qualify long-running capacity while legacy writes remain.
+4. **Enable v2 for fresh sessions with qualified peers.** Switch one authority
+   path per session. Stop full-journal writes and projection scans on that path.
+   Expand provider-by-provider after real-process and remote acceptance.
+5. **Migrate retained sessions once under an exclusive ownership fence.** At a
+   verified quiet boundary, stream the legacy journal/provider state into the
+   new stores. Preserve exact commands, receipts, unresolved work, cursors,
+   process owners, transition phases, and canonical identities. The lossy proof
+   projection is not a migration source. Import even valid files above 192 MiB
+   using bounded records/checkpoints and a resumable progress cursor; no whole
+   file allocation or 30-second whole-job deadline.
+6. **Commit migration with an explicit durable state machine.** Staging records
+   are invisible until verified. Record source identity/digest and import
+   generation. Prepare both controller/runner stores, then publish activation
+   through an idempotent fenced handshake. An interrupted migration is resumed,
+   not inferred complete from the presence of a directory. Preserve original
+   files until activation and backup verification; unsupported/ambiguous legacy
+   authority remains held rather than guessed.
+7. **Retire legacy readers after qualification.** A v2 session cannot silently
+   fall back to stale v1 JSON. Rollback disables new v2 starts but retains v2
+   recovery/read support. An older binary must reject v2 explicitly. Stopping
+   an active process to migrate requires the existing verified handoff; otherwise
+   leave that session on v1 until its natural safe boundary.
+
+Backup/restore must be transactionally consistent: use a database backup or
+checkpoint/export protocol, not a copy of a live `.db` without its WAL. Bind
+controller authority, runner state, required payloads, and provider checkpoints
+to one verified recovery generation. Revalidate actual process ownership after
+restore. Full historical backup is a streaming background operation and does
+not enter the resume path.
+
+## 11. Implementation slices and ownership boundaries
+
+These are ordered engineering slices, not newly created Paperclip tasks.
+
+| Slice | Principal code and outcome |
+| --- | --- |
+| A. Contracts and storage spike | `packages/paperclip-runner/src/control-plane/`, `runner/crates/runner-core/src/durable/`; qualify SQLite bindings/builds, async boundaries, corruption handling, and exact receipt API. Produce byte/read/write instrumentation. |
+| B. Controller authority | `packages/db/src/schema/`, migrations/exports, `packages/shared/`, native event coordinator and semantic dispatcher; commit event + authority + receipts atomically with tenant constraints. |
+| C. Runner and provider receipts | `durable/state.rs`, `durable/runner.rs`, `provider_bridge.rs`, `provider_backend.rs`, `acpx_provider_backend.rs`, and other qualified backends; remove history-sized maps/saves and receipt-triggered lifetime stops. |
+| D. Recovery consumers | `native-session-executor.ts`, continuation, process-stop, replacement, chat, and maintenance callers; consume typed evidence rather than scanning `commands`/`committedEvents`. Preserve each current negative-evidence check. |
+| E. Payload/history pipeline | Run-log payload storage, authenticated APIs, shared references, and transcript/download consumers; stream/chunk bodies and paginate catalogs without changing mutation authority. |
+| F. Compatibility and qualification | Legacy importer, capability negotiation, binary/provider manifests, backup/restore, fault tests, and real local/Daytona long-running cells. |
+
+Inventory every consumer of journal bytes/fingerprints and every provider's
+retained receipt collection before removal. Include helpers used by cleanup,
+hot restart, cold restart, backup restoration, and sandbox adoption. Do not
+change only the primary continuation call site.
+
+This is execution persistence and local run-log work. It is not first-party
+Telemetry or the OpenTelemetry trace path. Add local capacity/latency diagnostics
+without sending prompts, output, or credentials to a new endpoint.
+
+## 12. Acceptance gates
+
+Correctness and bounded I/O are mandatory. Wall-clock benchmarks supplement
+them; fast machines cannot hide a full-history scan.
+
+| Test | Required evidence |
+| --- | --- |
+| One long active run | At least 100,000 journaled commands and 100,000 settled semantic calls without a turn reset/provider restart, crossing all old count/byte thresholds. Exactly one application effect per logical key. |
+| Large real history | At least 10 GiB physically written and ingested through normal bounded events, crossing 192 MiB repeatedly; streamed hashes and independent host counts agree. No sparse padding offered as growth evidence. |
+| Larger storage qualification | 100 GiB scale lane plus tiny configured segment/partition thresholds; online rotation, partition split/relocation, and bounded startup work. A routing fixture alone is not a 100 GiB throughput result. |
+| Many continuations | At least 1,000 review turns with stable task/workspace/provider session where the provider supports it; no archive count loaded into memory. |
+| Multi-day soak | A real 72-hour session with periodic ordinary tool work, lease renewal, controller hot/hard restart, reconnect, and continued task output. Fake-time checks do not replace the elapsed soak. |
+| Resume scaling | Compare 10 MiB, 1 GiB, and 10 GiB acknowledged histories at the same active set. Instrument zero historical-payload reads and no receipt-table scans; current-state bytes stay bounded. Test cold and warm caches. |
+| Foreground latency | On a declared reference host, target p95 current-state read <250 ms and no >2x p95 regression between smallest/largest histories at fixed active work. Record provider/network time separately. Thresholds are qualification targets, not results already achieved. |
+| Write amplification | Trace each append/commit; no previous history serialized or rewritten. Measure total bytes written and bounded WAL/segment checkpoint batches throughout growth. |
+| Memory and fairness | Fixed active load plus growing history stays within configured caches and queues. A busy agent does not block another company's small continuation; control messages retain capacity. |
+| Ancient replay | Replay the first call/command after 100,000 later operations, archive, compaction, restart, and partition relocation: original outcome, zero second effect. Changed input under the same identity is rejected. |
+| Fault injection | Crash before/after payload durability, intent, external effect, receipt, DB commit, ACK, outbox removal, transition activation, partition cutover, migration cutover, and backup publication. Recover the correct phase without losing acknowledged work. |
+| Resource failure | Disk full/read-only, DB unavailable, upload failure, WAL checkpoint starvation, worker crash, and long network partition: bounded queues, preserved ownership, explicit reason, recovery after capacity returns. |
+| Integrity and governance | Corrupt active evidence, symlink/special-file swap, wrong tenant/account, stale fence, PID reuse, live mismatched owner, pause, budget exhaustion, and approval denial all remain denied. |
+| Archive independence | Make unrelated old history unavailable; normal continuation still succeeds. Remove an active receipt/checkpoint/body; the dependent operation fails closed with a precise reason. |
+
+Use deterministic credential-free processes for high-volume protocol tests.
+Run the actual provider/remote cells separately with explicit cost and cleanup
+accounting. A short three-turn test or synthetic scanner benchmark cannot satisfy
+the long-running claim. Preserve the qualification artifacts with exact code,
+runtime, provider, fixture, storage, and measured-byte provenance.
+
+## 13. Delivery standard
+
+The complete design is implemented only when the controller, runner, and
+qualified provider paths meet these gates, including restart and cleanup.
+The implementation status below distinguishes completed storage work from
+remaining rollout requirements. A reader improvement or short successful
+continuation must not be labeled unlimited continuation.
+
+The board-facing promise is: **an agent can keep working and continue later;
+the amount of completed work does not consume a hidden execution allowance.**
+
+## 14. Implementation and qualification status (2026-09-28)
+
+The worktree implements an **experimental local Codex lane**. Set
+`PAPERCLIP_NATIVE_INDEXED_STATE=1` to select it for fresh sessions. Existing
+legacy checkpoints remain legacy; they are not silently converted. Disabling
+fresh activation preserves the indexed readers and format selection for an
+already indexed local session, including its later runs.
+
+Implemented:
+
+- An asynchronous controller storage port, production Postgres authority and
+  immutable receipt tables, and a worker-owned SQLite implementation for
+  standalone controllers. Generation compare-and-set, binding checks, exact
+  replay comparisons, bounded records/pages, and failed-write fencing apply.
+  Credentials, event cursors, and delivery counters publish after commit. A
+  retained locator with a missing current-state row fails without recreating
+  authority or altering its surviving receipts.
+- A runner SQLite WAL/FULL executor, bounded current checkpoint and in-memory
+  receipt caches, exact command/event receipts, and paged pending outbox restore.
+- Codex provider checkpoints and exact tool-call, completed-turn, and child-thread
+  receipt indexes. Completed history no longer consumes the legacy 500-command,
+  4,096-call/identity, or 65,536-settled-call budgets on this lane. Limits on
+  current/pending work and individual records remain.
+- Explicit `durability.indexed_state.v1` negotiation; a PRP version alone does
+  not activate the format. SQLite is bundled and checked for the WAL-reset fix.
+- Current-state proof reads, generation fingerprints, sticky bootstrap/effect
+  facts, stale-writer rejection, transactional sealing of a verified stopped
+  runner, and resumable movement of inactive SQLite files during cold rotation.
+  A durable current-archive pointer avoids searching previous epochs after an
+  interrupted indexed rotation. Canonical archive identities survive reordered
+  JSON keys after reopening the indexed store; legacy archive names stay intact.
+- Cached contiguous run-log source cursors. Existing runs pay one bootstrap
+  scan; subsequent writes inspect only the indexed tail after that cursor.
+- A legacy writer guard that refuses to publish a journal its own reader cannot
+  reopen, instead preserving the last durable file and fencing the failed writer.
+  The locator compatibility reader shares that same 192 MiB bound; a real
+  65 MiB legacy-file regression prevents introducing a smaller reader limit.
+
+**Two event sequences must stay separate.** Runner transport events and the
+Codex driver's normalized Paperclip run-log events have different identities
+and sequence numbers. The Postgres adapter atomically commits the original
+protocol event into `native_authority_records` with current authority and the
+ACK cursor. The driver continues to publish normalized `heartbeat_run_events`
+through its existing writer. Inserting raw transport events into that table
+caused a replay conflict in an initial live test and was removed. The indexed
+lane now commits a driver checkpoint, raw consumer cursor and bounded normalized
+outbox together, publishing only after commit. Run-log ACKs remove exact pending
+events. Recovery restores unanswered questions and original event identities;
+an explicit terminal fact covers a crash after terminal delivery ACK but before
+orchestration checkpointing. Indexed driver recovery reads current provider
+metadata rather than enumerating provider turn history. Rotation drains pending
+normalized output through the prior run's writer. The driver history maps now use bounded exact caches. Remaining maintenance and
+import activation consumers still require the work listed below.
+
+The first live campaign for this handoff exposed optional `undefined` fields
+that needed JSON wire normalization and an error handler writing to an already
+failed writer. The next exposed ordering of deferred frames around provider
+identity. Another exposed a PostgreSQL deadlock; the adapter now retries only
+explicit PostgreSQL transaction-abort codes (`40P01`/`40001`), at most three
+times, preserving the fence for unknown commit outcomes. Real database rollback
+tests confirm one authority generation, receipt and run-log event. Campaigns
+`local-2026-09-28T19-07-40-740Z`, `local-2026-09-28T19-11-38-105Z`, and
+`local-2026-09-28T19-15-23-559Z` remain failed evidence. The first two also have
+interrupted automatic retry attempts; their infrastructure labels do not
+exonerate these implementation defects. Cursor-integrity failures now classify
+as candidate failures. The subsequent campaign
+`local-2026-09-28T19-20-22-653Z` passed on its first attempt: 124.7 seconds of
+browser work, server restart, authenticated answer, retained child and final
+document, with cleanup passed. Its final screenshot was inspected. It predates
+the subsequent epoch-tagged cursor/completed-frame boundary hardening.
+
+Additional checks during handoff implementation: 704 targeted runner tests
+passed before that hardening; a real runner/fake-provider autonomous goal case
+passed with a SQLite-backed normalized-event sink; nine Postgres coordinator
+tests, 81 E2E support tests, and focused normalized writer/question/terminal
+recovery tests pass. These results qualify this slice, not the remaining full
+design or the 72-hour soak.
+
+Evidence so far:
+
+| Layer | Observed result | Limit of the evidence |
+| --- | --- | --- |
+| Product E2E | The actual browser → Paperclip → Postgres → runner → Codex completed-action-resume case passed four times on indexed storage. Latest campaign: `local-2026-09-28T17-45-04-268Z`, 87.3 seconds of browser work; parent/child work, authenticated question response, continuation, final document and completion. | A short local workflow; no multi-day or remote qualification. |
+| Storage oracle | The final campaign independently inspected two indexed sessions: Postgres controller locators, valid runner/provider SQLite digests, positive generations and receipt counts. Runner current state was 12–27 KiB; provider state about 84 KiB. | Read-only format evidence, not a throughput measurement. |
+| Controller protocol | 100,000 authenticated sequential commands, ancient exact replay after restart, conflicting replay rejection; current checkpoint under 8 KiB. The final-code rerun passed in 543 seconds during concurrent local test load (earlier run: 234 seconds). | Synthetic protocol peer; this does not represent 100,000 real business effects. |
+| Provider bridge | 100,000 settled calls in one bridge without resetting the turn; current state under 2 KiB; first-call exact replay and changed-input rejection after reopen. Latest run passed in 45.1 seconds. | Storage/bridge test, not paid provider throughput. |
+| Identity indexes | 5,000 completed turns plus 5,000 child identities, empty memory sets, first-identity lookup after reopen, corrupted-receipt rejection. | Identity storage, not 5,000 model continuations. |
+| Physical history | 100 GiB of non-sparse receipt payload writes passed in 954 seconds (108,332,896,256-byte SQLite file). Current state stayed 21 bytes. At 100 GiB: reopen 0.467 ms, current-read p95 0.012 ms, 16 MiB batch-commit p95 193.9 ms. At 16 MiB: reopen 0.505 ms, read p95 0.018 ms. | SQLite executor benchmark with warm OS caches and concurrent local test load, not 100 GiB ingested through the full product. This earlier measurement predates range partitioning. |
+| Fault boundaries | Stale generation, immutable receipt conflicts, rollback, missing activated store, damaged digest, readonly proof reader, stale/unsettled seal, interruption between DB move and locator publication, and direct archived-authority recovery with unavailable unrelated epochs are tested. | Does not cover every crash/failure point in section 12. |
+| Startup compatibility | The standalone real Codex startup-failure qualification passed after updating its asynchronous controller calls; durable intent/spawn/failure evidence survived reopen and blocked a new launch. | Local Codex 0.156.0, no model turn; not a multi-day recovery test. |
+
+An initial indexed live attempt failed on the raw/normalized sequence conflict.
+A second attempt was interrupted after a storage-write failure and exposed a
+missing awaited shutdown operation. Optional command fields are now serialized
+according to their wire JSON before durable validation, writes publish only
+after commit, and shutdown callers await their commands. Both subsequent indexed
+campaigns passed. A subsequent rerun exposed a Postgres `40P01` deadlock;
+its automatic retry completed the browser workflow but failed the persistence
+scan when Postgres recycled a WAL segment. The authority adapter now acquires
+issue/run locks before authority/receipt writes, with a regression that observes
+the actual lock wait and verifies current authority stays accessible. The
+scanner tolerates only a missing canonical WAL-segment filename; existing WAL
+bytes are still scanned. Authority deadlocks now classify as candidate failures,
+not retryable provider infrastructure. These attempts remain recorded as
+failures. The fresh campaign after both fixes
+passed its browser workflow, independent storage oracle, and cleanup on its first
+attempt. Its final screenshot was visually inspected; no manual browser
+walkthrough was performed. The interrupted fixture's four owned runner/provider
+process groups were revalidated and stopped; its temporary directory was removed.
+A final process audit also found two orphaned runner/provider pairs from the
+deadlock attempt after the harness had reported cleanup success and removed its
+fixture directory. All four exact process groups were revalidated and stopped.
+The harness now observes exact descendant process identities while the wrapper
+is alive and revalidates them on both normal and failed exits, including after
+reparenting. A real-process regression starts a detached child, exits its wrapper,
+then verifies and stops the retained child. Reused PIDs/groups are excluded.
+The final campaign after the archive and cleanup fixes passed on its first
+attempt and left no matching processes in the independent audit. A polling
+observer can still miss a process created and orphaned entirely between
+observations, so this does not replace production process-ownership recovery
+qualification.
+
+Local checks also pass: repository recursive typecheck and build; 299 Rust
+library tests; 113 focused controller/storage/protocol tests; 482 server
+registration/recovery tests; 20 transport settlement/current-state tests; seven
+Postgres coordinator tests plus activation and cached-cursor gap regressions; and
+554 Product E2E harness unit tests (including the real detached-child cleanup
+regression), plus ten targeted cold-rotation/archive cases. The complete runner
+TypeScript suite passed 2,100 tests across 152 files, with ten tests and one file
+skipped; its protocol/script preparation passed another 38 tests. The separate
+65 MiB compatibility regression passed. The initial runner-wide attempt exposed
+test fixtures that used the checkout under sensitive `~/.codex` as provider CWD,
+and fault hooks still intercepting the former synchronous constructor. Those
+fixtures now own private temporary workspaces, and crash tests intercept/await
+the asynchronous factory and command lookup. All 29 affected warm-recovery fault
+cases passed before the complete rerun. The archive routing fixture was reduced
+from 1,000 unrelated filesystem entries to 128 after a five-second test timeout;
+it tests direct routing, not volume qualification. The complete rerun used four
+workers. A broad
+`pnpm test:run` attempt passed 25,141 tests before the company-import route suite
+timed out while starting its embedded database; its assertions did not run.
+Resuming the exact serialized-suite catalog completed all 149 suites (2,723
+tests). Combined with the original general/workspace passes, all selected suites
+have a passing result: 27,226 tests. Company-import, company-skills and inbox-agent
+policy suites needed a retry after timeout failures. The original full command
+did not pass; the continuation uses an explicit suite manifest and preserves
+the failed attempts. Tests ran on macOS arm64 with
+Node 26.4.0 (SQLite 3.53.2) and Cargo 1.97.1. The newly generated migration adds a
+unique index on existing heartbeat runs, so deployment timing on a large
+existing database still requires qualification.
+
+The live report and screenshots are under
+`tests/runner-e2e/results/local-2026-09-28T17-45-04-268Z/continuation/runner-codex/local/completed-action-resume/attempt-1/`.
+Its `snapshots/indexed-storage.json` contains counts/sizes only. Local campaign
+source fields are null in the existing harness; the accompanying external
+provenance record captures the baseline SHA, tracked diff digest, and hashes of
+new source files. These runs used the uncommitted worktree, not the baseline
+commit alone. Billing data reported zero cost with unknown billing type; that
+is not evidence that the provider execution was free.
+
+Additional implementation (same worktree, subsequent qualification):
+
+- The normalized Codex reducer now uses 128-entry exact receipt caches for
+  completed turns, emitted file references, steering acknowledgments, and
+  historical thread ancestry. Receipts commit with reducer state and its outbox.
+  Session-scoped effect indexes survive run rotation; an uncached key requires
+  a durable lookup. A 2,000-receipt SQLite test proves eviction, reopen, ancient
+  replay, cross-run lookup, and rollback on conflicting identity reuse.
+- New Rust indexed stores use a version-2 routing database and range-partitioned
+  immutable receipt files. The default split threshold is 256 MiB; individual
+  records remain bounded. A root transaction commits current authority and a
+  bounded redo intent containing its new receipt bodies. Reopen completes that
+  intent before serving the runner. Direct proof readers validate the matching
+  current generation; verified stopped-runner sealing updates both the current
+  row and any matching redo intent.
+- Range copies use bounded pages, a fixed copy boundary, write mirroring, and
+  count/size/content-fingerprint verification before atomic routing cutover.
+  An indexed maintenance queue avoids scanning all partitions to choose work.
+  Maintenance credits scale with admitted bytes so sequential output cannot
+  indefinitely outrun splitting. Receipt keys stay stable during relocation to
+  another private volume. Ordinary reads consult the routing index, not a file
+  list. Relative local partition paths survive cold archive directory renames.
+  Legacy version-1 indexed files are still opened in their original format.
+- Tiny-threshold tests cover concurrent writes during split, cross-range pages,
+  ancient replay after reopen, prepared-write recovery, a missing required
+  partition, and restart during relocation. Reader/archive tests cover both
+  local formats and sealing with a committed redo intent. These do not establish
+  full backup, migration, corruption, or resource-failure qualification.
+- After these changes, 558 driver/controller/transport tests, nine PostgreSQL
+  coordinator tests, the selected real-runner Codex goal harness, and targeted
+  cache/reader/archive tests pass. Rust indexed tests passed before the final
+  redo-envelope checks; the three partition tests passed after those checks.
+  New full-repository checks and large partition qualifications remain pending.
+- The live browser campaign `local-2026-09-28T20-04-38-665Z` passed on its first
+  attempt, including restart, structured answer, retained child, final document,
+  indexed-storage evidence, and harness cleanup. A command-line process audit
+  found no remaining processes naming its fixture. Source provenance is in
+  `/tmp/paperclip-journal-indexed-e2e-source-13.json`. The earlier campaign
+  `local-2026-09-28T19-58-55-384Z` was stopped after the model declared the parent
+  blocked waiting for an already-completed child and produced no question.
+  Both native runs had succeeded. Its mechanical interrupted result says
+  infrastructure; the observed completed behavior is a model/product workflow
+  failure, recorded separately in `/tmp/paperclip-indexed-e2e-12-observation.json`.
+  It is not counted as a passing test or an infrastructure-only failure.
+
+Latest storage and import work (same worktree):
+
+- Range metadata now records the expected receipt count, bytes and content
+  fingerprint. Lookups verify the routed receipt set before interpreting a miss.
+  Prepared commits record each range's expected final set; recovery rejects a
+  replaced/incomplete shard or missing routing intent instead of adopting it.
+- Local indexed storage supports resumable online snapshots. A root snapshot
+  pins its source partitions; bounded pages copy only receipt insertion ordinals
+  present at the snapshot. Writes and splits continue between pages. Each target
+  range must match the snapshot's expected receipt set before publication. A
+  backup-in-progress marker prevents opening an unfinished snapshot as execution
+  authority. Restart/concurrent-write tests verify exact restoration and absence
+  of later receipts. This is a **single-store** snapshot primitive; the complete
+  controller/runner/provider recovery-generation handshake remains required.
+- Operator commands expose paged partition inspection, bounded maintenance,
+  relocation and resumable backup (see the runner architecture document). Cleanup
+  visits one retired range per step even when a backup pins many ranges. Write
+  transactions disable intermediate cache spilling; dirty pages are bounded by
+  the admitted transaction, while ordinary read caches remain bounded.
+- A worker-owned, lossless legacy controller reader imports pages without a
+  total file-size limit. Its checkpoint binds source inode/size/timestamps,
+  byte offset, parser position and a chained prefix digest. Staging commits exact
+  command/event rows with the import cursor, then resolves semantic inputs using
+  indexed command receipts. A >192 MiB journal test resumes after interruption,
+  preserves ancient receipts, keeps its current projection below 16 KiB, and
+  rejects changed source/ownership. Source JSON remains untouched; staged rows
+  cannot serve execution authority. Runner/provider staging and three-store activation were added subsequently;
+  automatic production admission remains incomplete (see below).
+- The real runner/fake-provider lane completed **1,000 run continuations** with
+  unchanged runner/provider PIDs in 910.3 seconds. First/last 100-turn means were
+  1,151.79/694 ms and p95 was 1,888 ms. The test uses real transport and stores,
+  but a raw consumer rather than the complete Codex normalization/product path.
+  A separate actual-driver test processes 300 child threads, evicts old cached
+  ancestry and accepts a later descendant through an exact stored lookup while
+  keeping current state below 100 KiB.
+- The partitioned **10 GiB** lane passed in 701.8 seconds with 79 partitions;
+  the largest file was 270,761,984 bytes and current state remained 21 bytes.
+  At 1/10 GiB, current-read p95 was 0.038/0.032 ms and reopen was 0.548/0.650 ms.
+  Batch-commit p95 was 4,872.7/1,847.4 ms under concurrent local test load.
+  This predates the subsequent route fingerprints, backups and cache-spill
+  change. A subsequent 100 GiB run on those changes passed (results below).
+- 307 Rust library tests plus four runnerd binary tests passed before the cache
+  spill setting changed. Fourteen focused TypeScript storage/import/archive
+  tests passed; the additional actual-driver ancestry test also passed. The
+  current package TypeScript and runner binary builds pass. Full-repository
+  checks have not been rerun for these additions.
+- A **72 real hour active-turn soak** started at `2026-09-28T21:04:30.450Z`.
+  It uses a held fake Codex process, a real runner, real stores and a metadata
+  probe every 30 seconds. It tests active-turn lifetime/lease behavior without
+  paid inference; it does not qualify a hosted provider or sandbox TTL.
+  Progress is in `/tmp/paperclip-indexed-72h-soak.json`; source provenance is in
+  `/tmp/paperclip-indexed-72h-soak-source.json`. It is still running, not passed.
+
+Remaining before the **full unlimited-history promise** or default activation:
+
+1. Connect retained-session migration to automatic production recovery admission
+   and resumption. Rust now stages exact runner/provider receipts in bounded
+   batches; the controller coordinator rolls forward all three stores under one
+   durable migration marker. Original files remain private and inspectable.
+   Every phase checks the caller's exclusive process fence, and the production
+   Postgres entry point checks its coordinator lease inside each commit. The
+   executor does not yet supply/call that complete process-ownership admission.
+   A real runner/fake-provider test interrupts eleven activation boundaries,
+   rejects changed sources, imports a >192 MiB journal, and completes a cold
+   continuation on the original provider thread. This is protocol evidence,
+   not a hosted-provider migration result.
+2. Separate validated completion references, process-owner retirement and all
+   recovery/maintenance consumers. Current compatibility views retain selected
+   current commands/events and unresolved startup ownership; they are not the
+   complete typed-evidence contract in section 5. Copy-based retained maintenance
+   is not qualified for indexed authority. The new bounded driver caches need
+   broader long-running and recovery qualification beyond their targeted tests.
+3. Durable raw-inbox/normalized-consumer handoff and crash/fault coverage across
+   effect, ACK, transition, restart, cleanup, and backup boundaries.
+4. End-to-end PRP payload references; large-volume and fault qualification of
+   the new local partitions; production operator controls for relocation.
+   Stdout/stderr now use fixed 32 MiB segments, an exact cursor API, bounded
+   mirroring, and compatible board viewers. This does not externalize semantic
+   command/event bodies. Fresh standalone SQLite controllers now reuse the partitioned native store
+   through a bounded private stdio port; retained prototype v1 files stay in their
+   original format. Production controller records live in Postgres.
+5. Other providers and remote/Daytona activation; exact cursor epoch rollover;
+   control/settlement admission reserve; operational backup/restore qualification.
+6. Finish real elapsed-time qualification and live restart/resource-failure
+   coverage. The 1,000 protocol continuation lane has passed; the active-turn
+   72-hour soak is running and is not yet a passing result. Hosted-provider and
+   remote lifetime qualification remain separate.
+
+Further local results on 2026-09-28:
+
+- Migration: ten focused Rust legacy tests, seven TypeScript import/gate/proof
+  tests, eleven server Postgres fence/coordinator tests, and the real-process
+  migration/continuation test pass. The latter writes >192 MiB of synthesized
+  historical diagnostic events; those are not hosted model calls.
+- Segmented stdout: 34 storage/compatibility tests and eight viewer/cursor tests
+  pass; server/UI TypeScript and token gates pass. The scale lane physically
+  writes 268,439,488 bytes through normal append, independently hashes the full
+  paged output, and continues with an old segment unavailable. It produced nine
+  segments, 268,439,552 allocated bytes and a 246-byte current head. Append time
+  was 3,114 ms, reopen 1.49 ms and finalization 52.71 ms under concurrent local
+  qualification load. This is a local storage result, not remote throughput.
+  Report: `/tmp/paperclip-segmented-log-scale.json`; source hashes:
+  `/tmp/paperclip-segmented-log-scale-source.json`.
+- Segmented S3 behavior is tested against an in-memory provider with checksums,
+  interrupted publication and local-volume-loss restoration. The remote tail
+  mirror interval remains an explicit durability window. No live S3 service
+  qualification has passed for this new format.
+- Partitioned 100 GiB storage: passed in 5,555.0 seconds, 799 partitions,
+  108,507,676,672 partition-file bytes, 121,366,106,112 allocated partition bytes,
+  largest file 270,962,688 bytes. Current state stayed 21 bytes. At 100 GiB,
+  reopen was 0.471 ms, current-read p95 0.030 ms and 16 MiB batch-commit p95
+  1,616.4 ms. These are synthetic storage measurements under concurrent local
+  load, not full-product throughput. Log: `/tmp/paperclip-partition-growth-100gib.log`;
+  source provenance: `/tmp/paperclip-partition-growth-100gib-source.json`.
+  This run predates the subsequent store-lifetime lock and standalone RPC port.
+- Product campaign `local-2026-09-28T22-14-31-910Z` passed on its first attempt,
+  including server restart, authenticated answer, continuation, retained child,
+  final document and cleanup. Saved run records confirm `local_segments` storage.
+  The screenshot was inspected. Provenance:
+  `/tmp/paperclip-journal-indexed-e2e-source-15.json`. This predates the subsequent
+  native archive/standalone-controller changes.
+- Native archival and sealing now hold exclusive store-lifetime locks; every
+  native SQLite connection holds a shared lock through its final close. Prepared
+  archive intents fence new opens. A live or interrupted backup prevents archive
+  publication until it is complete. Transfers retain a fixed file list and use
+  atomic no-clobber renames; a test resumes after root movement before locator
+  publication. Three backup tests, nineteen indexed Rust tests and six TypeScript
+  archive/proof tests pass. Read-only proof snapshots remain advisory until the
+  caller revalidates ownership/generation.
+- Fresh standalone controllers use the same partition/redo engine through a
+  bounded storage-only subprocess. Exact record identity, per-epoch sequence
+  ownership and session-wide effect identity commit together with current state.
+  Existing v1 controller files use their compatibility worker. The focused
+  controller/cache/archive suite passed 101 tests, including tiny-partition
+  rotation and ancient replay. The 100,000-command rerun passed in 421.03 seconds using the native partitioned RPC store.
+- Runner binary staging now signs a temporary inode and atomically replaces the
+  published path, preserving the executable mapped by already-running agents.
+- Full-repository checks must be rerun after these additions.

+
+## 15. Subsequent implementation evidence (2026-09-28 evening)
+
+The rollout remains explicit. The full acceptance gates above are unchanged.
+
+- Lossless output now traverses real runner transport, the Codex driver and an
+  independent durable normalized-event sink. Chunk and body digests are checked;
+  message and command previews carry immutable download references. A mandatory
+  authenticated `history.output_bodies.v1` capability prevents using an older
+  runner that would silently truncate this output.
+- The latest mixed-output 64 MiB lane passed in 152.35 seconds: 256 completed
+  message/command items, 2,582 normalized events, 67,108,864 body bytes and
+  252,183,481 physical bytes. Current controller/runner/provider states were
+  37,285 / 1,954 / 23,510 bytes. Current-state reads took 39.89 ms; a warm
+  continuation took 1,694.02 ms with the same runner and provider PIDs. Report:
+  `/tmp/paperclip-command-history-pipeline-smoke-2.json`. This is a fake-provider
+  protocol measurement; it is not paid provider throughput or the 10 GiB result.
+- The earlier 10 GiB ordinary-message lane is still running, with separate source
+  provenance. It predates mixed command-output coverage and is not a passing
+  result yet: `/tmp/paperclip-history-pipeline-10gib.json`.
+- The active-turn fixture now performs steering, generates real output events,
+  durably consumes every chunk, verifies hashes and probes bounded current state.
+  Its 60-second check passed with 45 output items, 369,351 bytes and unchanged
+  processes. A separate 72-hour run began at `2026-09-29T00:58:32.494Z`; report
+  `/tmp/paperclip-active-history-72h.json`, source hashes
+  `/tmp/paperclip-active-history-72h-source.json`. It uses a fake provider and
+  does not yet test controller restart, hosted provider lifetime or remote TTL.
+  The older held-turn/metadata-only soak remains separate evidence.
+- Hosted Codex campaign `local-2026-09-29T00-29-22-400Z` passed browser task
+  creation, server restart, an authenticated answer, continuation, retained child,
+  final document and cleanup. The storage oracle inspected both indexed sessions.
+  The final screenshot was inspected. It did not exercise a large-output download.
+- The new explicit `indexed-history.runner-codex.local.large-output-resume` cell
+  tests that download before and after restart/continuation. Its first product
+  run exposed an omitted tool-output schema reference: chunks committed, but the
+  completed command event was rejected. Both PRP versions now validate the body
+  reference; 55 provider/schema tests and 12 schema-contract tests pass. Failed
+  campaigns remain recorded. A fresh live campaign is in progress.
+- Indexed restart recovery no longer queries the latest historical provider
+  events. It verifies the current binding/digest/sticky facts and reads unresolved
+  owners in generation-fenced pages of 128. A 260-owner test proves that an
+  unresolved intent on the last page blocks recovery. Thirteen coordinator tests
+  pass. A prototype owner-index upgrade now resumes after an indeterminate page
+  commit without replaying an older phase over a newer one.
+- Server-observed process launch/stop checks use a current Postgres row; a new
+  launch invalidates the stop atomically. Retained runs receive one compatibility
+  backfill. Two PostgreSQL tests verify rollback, concurrent backfill, rejected
+  provider claims, company scope, and positive/negative reads with the historical
+  event table unavailable. This does not establish escaped-descendant retirement.
+- Public chunk events omit raw fragments. Authorized downloads apply secret
+  redaction to the assembled frame. Feedback event exports have both byte and
+  row budgets; plan synchronization in the final result is a recent 128-entry
+  display excerpt, with full activity/document revision receipts retained.
+- Sealing rejects a pending migration before modifying state. Local RPC request
+  IDs recycle only after settlement instead of growing a JavaScript lifetime
+  counter. The controller/store/normalized-delivery suite passes 102 tests.
+- Product E2E has an explicit isolated Docker PostgreSQL 17 backend with verified
+  container ownership, loopback-only ports, recorded immutable image ID and exact
+  cleanup. This bypasses the host's exhausted native Postgres semaphore pool; it
+  does not qualify the embedded launcher. Five backend ownership tests pass.
+- The full repository test command failed when Docker stopped during database
+  suites (10,734 tests passed; many database suites never ran). Its earlier-loaded
+  feedback module also failed the new redaction assertion; the later focused
+  PostgreSQL/redaction runs pass. The failure is retained at
+  `/tmp/paperclip-unbounded-full-tests-2.log`. Docker is running again; a new full
+  run and recursive typecheck are underway. No full green hand-off is claimed.
+
+These additions do not close automatic legacy migration admission, full typed
+completion references, exact process-owner retirement, indexed maintenance and
+whole-session backup/restore, arbitrary semantic payload references, remote and
+other-provider activation, safe cursor epoch rollover, recoverable resource
+pressure, or the elapsed-time gates listed in section 14.
+
+## 16. Object-backed payloads and current evidence references
+
+The next implementation slice adds immutable company/run-scoped payload storage
+through the configured local/S3 provider. Output chunks and controller receipts
+larger than 16 KiB are published only after upload and exact read-back
+verification. Postgres migration `0290_broken_warbound` stores encoding and
+original byte length, so pages are budgeted by resolved bytes rather than tiny
+reference sizes. Failed metadata transactions leave reusable immutable objects,
+not dangling references. Required missing/corrupt objects fail closed; automatic
+orphan GC and hosted-S3 qualification remain open. Local publication fsyncs all
+new ancestor directory entries as well as the file and its immediate directory.
+
+Persisted current authority v2 replaces settled payload copies with a fixed set
+of named command/event receipt references. Recovery resolves only those exact
+IDs, validates scope/sequence/digest and slot, then rechecks generation. The
+existing structured completion and server-accepted business-result checks are
+preserved. Native read-only receipt lookup uses the same lifetime/operation
+fences, routing index and partition fingerprints as the writer, without creating
+or repairing storage. Old binaries reject the new current-state version.
+
+Authenticated spawn failures that created no child now retire their current
+intent, atomically with the immutable failure receipt. A direct-child exit after
+successful spawn still does not establish whole-process-tree retirement.
+Controller storage pressure can be retried on the same owner only when a fresh
+read proves the durable generation and state did not change; uncertain commits
+and unreadable storage remain fenced. This is not yet a complete runner/provider
+resource-pressure recovery loop.
+
+Validation at this slice:
+
+- Live hosted Codex/browser campaigns 23, 24 and 25 passed the exact full-output
+  download, server restart, continuation and repeat-download oracle. Campaign 24
+  includes object-backed payloads; 25 also includes current receipt references.
+  Campaign 25 is `local-2026-09-29T02-10-34-656Z`, with an 18,432-byte original-run
+  download verified before and after continuation. Earlier failed campaigns
+  remain recorded separately.
+- Current reference/controller tests: 97 passed. Four focused server files:
+  494 passed, including all 474 native-session tests. Payload/streaming fsync
+  tests: 7 passed. The native read-only proof test passed.
+- The full Rust workspace suite passed before the final read-only-reference
+  addition (318 unit tests plus integration suites); that addition has its own
+  passing focused test. Full TypeScript runner validation found three timeouts
+  under concurrent load. Both migration tests passed on isolated retry; the
+  2,000-receipt cache test received an explicit 30-second storage-test timeout.
+  A final complete rerun is still required.
+- Full recursive typecheck and build passed at the earlier campaign-23 snapshot.
+  Current package build and server typecheck passed. The broad root test campaign
+  remains underway and has failures; no full green hand-off is claimed.
+
+The remaining rollout gates still include production legacy migration admission,
+retirement of spawned process trees, indexed maintenance/whole-session backup,
+remote/other-provider activation, cursor rollover, full resource-pressure
+recovery, and elapsed-time qualification. Fresh indexed sessions remain opt-in.
+
+## 17. Backup readers and current-state archive fencing
+
+Harness backup verification now streams files in 64 KiB chunks and sorts
+directory entries through bounded external merge pages. It preserves the
+existing v1 digest format, checks file/directory identity across reads, and
+never follows symlink targets. Manifest reads are limited to 64 KiB metadata
+and the four supported provider directories. Verification yields to the event
+loop and rechecks the manifest before accepting it. Full verification still
+reads every backup byte; ordinary indexed continuation does not use this path.
+This does not yet provide a consistent checkpoint across all session stores.
+
+Cold archive now compares the materialized authority with the admitted state
+but fences the native operation using the digest of the exact persisted v2
+reference snapshot. Hashing the materialized compatibility view was incorrect.
+The mixed-output qualification inventory tolerates SQLite removing a transient
+WAL/SHM file between enumeration and stat; missing persistent files still fail.
+
+Validation at this slice:
+
+- Backup/executor tests: 477 passed. New cases preserve the independent v1
+  digest oracle for over 4,000 files, stream a 128 MiB file while the event loop
+  remains responsive, and reject a symlink root.
+- Current-reference archive tests: 6 passed. Full recursive typecheck passed.
+- A 64 MiB mixed-output pipeline passed with 2,582 events, 256 items, a peak
+  current-state size of 50,643 bytes, and continuation using the same runner and
+  provider processes. This uses a fake Codex fixture with real storage/delivery.
+- A local MinIO qualification passed immutable 1 MiB upload/readback, exact
+  replay, fresh-provider reopen, company-scope rejection, missing-object
+  rejection, and verified owned-container cleanup. Hosted S3 remains unqualified.
+- Hosted Codex/browser campaign 25 passed earlier with exact original output
+  verified before and after restart/continuation. The 10 GiB and two 72-hour
+  campaigns are still running on their recorded older source snapshots; none
+  is reported as passed. The broad root suite had 19 failures and requires a
+  clean final-candidate rerun; targeted retries do not replace that gate.
+
+## 18. Streaming remote transfer and retained maintenance
+
+The generic remote checkpoint fallback now spools archives on disk and transfers
+192 KiB binary chunks through the command transport. Whole-archive byte counts
+and SHA-256 must agree before extraction/publication. Archive validation streams
+the member listing with a per-entry bound, rejects links and escaping paths, and
+preserves the prior checkpoint on failure. There is no aggregate 64 MiB or
+20,000-entry limit in this transfer. The remote host needs `tar`, `base64`, `dd`,
+`wc`, and `sha256sum` or `shasum`. Archive operations request no total command
+deadline; actual provider bulk-transfer limits still require qualification.
+Native upload exclusion staging also uses disk spools rather than tar buffers.
+
+Daytona archive validation now streams its listing, top-level file names are
+spooled as NUL-delimited catalogs, and file counting uses bounded directory
+iteration. These changes remove accumulated-list and process-argument limits;
+they do not qualify remote lease renewal, provider bulk deadlines, or indexed
+runner activation in Daytona. No live Daytona campaign is claimed here.
+
+Retained local cleanup now hashes and copies files in bounded chunks and streams
+the existing metadata/content fingerprint formats. It no longer builds an
+array containing every provider-home entry or rejects homes above 64 MiB.
+Rollout relocation reads only the session header. Stopped-text-turn recovery
+streams JSONL records; its v2 receipt explicitly uses a raw-byte transcript
+digest instead of hashing one giant JSON string. Current completion-call
+identities bound the replay inventory. Large scans renew their exact cleanup
+lease, including through the final transaction using that transaction's own
+connection; a renewal failure is retained and rejects subsequent admission.
+
+Backup construction syncs copied file contents and directory entries, then
+syncs the manifest and backup rename before recording a lease backup stamp.
+This strengthens durable publication; a cross-store point-in-time checkpoint
+still needs the separate whole-session backup protocol described above.
+
+Validation at this slice:
+
+- 480 transfer/backup/executor tests passed, including a compressed archive
+  over 64 MiB, 20,100 entries, bounded requests/responses below 300 KB,
+  corruption, and rejection of unsafe links while preserving old state.
+- 498 cleanup/recovery/executor tests passed, including retained fingerprint
+  compatibility, a 3 GiB sparse rollout header, a transcript over 32 MiB,
+  source mutation, lease-renewal serialization and persistent lease failure.
+- Daytona file-sync/plugin tests: 285 passed, 6 skipped; this includes a
+  streamed listing larger than 32 MiB and literal filename handling.
+- The four TypeScript runner files that timed out under concurrent load passed
+  sequentially (177 tests). Full runner/Rust reruns are still being completed.
+  The Rust legacy receipt-limit fixture was corrected to retain all events in
+  an acknowledged batch and verify either authoritative interruption or the
+  documented conservative shutdown after its wall-clock deadline expires.
+
+The production migration, complete owner retirement, whole-session checkpoint,
+other-provider indexed activation, cursor rollover, resource-pressure control
+lane and elapsed-time gates remain open. Indexed fresh sessions stay opt-in.
+
+## 19. Recovering native writes when capacity returns
+
+The active indexed native runner now suspends an exact storage operation on
+SQLite `SQLITE_FULL` or filesystem full/quota errors. It applies backpressure
+to provider output while continuing authenticated ping, lease renewal, revoke,
+and stop handling. Restoring capacity resumes the original operation; it does
+not execute the command or external effect again. Per-record and transaction
+bounds remain admission failures, not indefinitely retried physical failures.
+
+Each commit has a private operation UUID and a length-framed fingerprint of its
+state, receipts and work changes. A bounded current-commit stamp is committed
+with the root update and redo. An interrupted leaf materialization can resume
+that same committed operation without applying a work CAS twice or incrementing
+the authority generation again. A different owner, changed bytes or superseded
+generation fails closed. Only idempotent storage steps use capacity retry.
+
+The control lane admits at most 128 deferred commands/32 MiB and coalesces
+consecutive cumulative ACKs without reordering commands or accepting regression.
+Explicit deadlines and lease expiry still apply. A stop during disk exhaustion
+stops owned work but does not fabricate a durable success receipt; a previously
+admitted effect remains indeterminate for reconciliation. No unbounded output
+queue or historical checkpoint clone is introduced.
+
+Validation at this slice:
+
+- Five encrypted-transport tests exercised actual SQLite `SQLITE_FULL`, capacity
+  restoration, welcome-delivered commands, renewal/ping, revoke/stop, 20,000 ACKs,
+  bounded control admission and indeterminate replay after cancellation.
+- Indexed commit tests exercised root-commit/leaf-redo interruption, exact retry,
+  conflicting receipts/work/body, changed owners and superseded generations.
+- Full Rust workspace passed, including 327 library tests (1 ignored), 89 Codex
+  integration tests (2 ignored), the other integration suites and doc tests.
+- Full runner TypeScript suite passed: 2,134 tests across 161 files; 14 tests and
+  5 files skipped. The full repository test rerun remains a separate gate.
+- Hosted Codex/browser campaign `local-2026-09-29T04-07-32-008Z` passed with the
+  rebuilt native binary. It downloaded the exact 18,432-byte original output
+  before and after restart/continuation; SHA-256 was
+  `61fe29fb637703eb94262fd93c91ebdb514ea71175ac85ffd4ed79de4034f9e0`.
+  Its source record includes the runner binary hash and database image identity.
+
+This closes the active local native storage-wait slice, not the whole resource
+failure gate. Warm-attachment/disconnected writes, whole-session maintenance,
+Postgres/object-store recovery and the vendor provider's own filesystem still
+need qualification. Fresh indexed sessions remain opt-in.
+
+## 20. Verified historical reads and real object-store restoration
+
+Historical reads now validate each completed segment's bounded sidecar and
+SHA-256 before exposing any page. Current tails validate the exact prefix and
+digest from the head. Verification reads at most one 32 MiB segment at a time;
+the store retains at most two verified segments and admits at most two distinct
+verification jobs. Returned pages copy only their requested bytes. First-page
+I/O therefore includes a bounded verification read; later pages can reuse the
+cache. Neither path scans total historical output.
+
+Validation at this slice:
+
+- The log suites passed 33 tests including local and remote corruption outside
+  the requested page, wrong bindings, bounded cached verification and the
+  explicit 256 MiB growth qualification. That qualification wrote 268,439,488
+  physical content bytes across nine segments, with a 246-byte head and a
+  2.44 ms reopen on this host. These are measurements, not latency guarantees.
+- A real loopback MinIO qualification passed 75,498,693 bytes of segmented output:
+  two closed 32 MiB segments plus a current tail, a 330-byte head, local-volume
+  loss, remote restoration, append, streamed whole-history verification,
+  corruption rejection and missing-history independence of current work.
+  Reopen fetched no historical segment. Owned-container cleanup was verified.
+- The same qualification revalidated immutable payload upload/readback. MinIO
+  image identity was
+  `sha256:14cea493d9a34af32f524e538b8346cf79f3321eff8e708c1e2960462bd8936e`.
+  A first fixture attempt hit MinIO's minimum-free-space protection; it was
+  preserved as failed evidence and rerun with a sufficiently sized owned tmpfs.
+
+This is a local real S3-compatible API result, not a hosted AWS or remote runner
+qualification. Conditional head ownership and orphan/tail garbage collection
+remain separate work. The successful hosted browser campaign above predates the
+verified-segment reader change; the latter has its own storage qualifications.
+
+## 21. Migration leases survive history-sized jobs
+
+The already-quiesced migration service now renews a 60-second ownership lease
+throughout streaming preparation and activation. Each renewal matches company,
+issue, run, attempt, lease owner and the exact controller process identity, and
+checks expiry using PostgreSQL wall-clock time. Publication transactions renew
+on their own connection rather than awaiting a renewal blocked on their row
+lock. A failed or timed-out renewal permanently cancels staging; late database
+success cannot revive that owner. Cancellation waits for the owned storage-only
+subprocess to exit before returning. It never launches provider work.
+
+Four lease-control tests passed. Three targeted Postgres coordinator tests passed,
+including a migration held beyond multiple original lease periods, exact owner
+replacement, transaction-local wall-clock expiry and a background renewal blocked
+on the publication transaction. This service still requires the caller's explicit
+stopped-tree proof; this change does not invent such proof or wire automatic
+legacy activation. That admission work remains a separate rollout gate.
+
+## 22. Remote publication fencing and bounded tail cleanup
+
+The segmented-log v2 head now requires an atomic conditional object write. A
+writer claims a fresh UUID using the remote head's exact ETag before admission.
+Every subsequent head publication uses that owner’s last ETag. An old writer's
+delayed upload cannot roll the head back. Segment bodies use immutable
+content-addressed keys. Their ordinal references are published with their own
+ETag condition after checking the head owner. The reference includes the writer
+UUID, so reusing identical bytes cannot create an ETag ABA across ownership.
+An interrupted, unpublished segment may be replaced; published historical bytes
+are never overwritten. The v1 format remains readable and upgrades explicitly
+on write; an older reader rejects a v2 head.
+
+Normal mirroring retains one current tail and one durable pending deletion,
+not every historical tail revision. A reader that races deletion refreshes once
+and verifies its original head's exact prefix against the newer content. An
+ownership-only change avoids joining the reader's own identical cache key.
+Cleanup failure fences further appends until reopen completes the deletion.
+Unknown prepublication failures may still leave orphan objects for independent
+maintenance. This protocol does not replace the caller's exclusive ownership of
+local filesystem paths.
+
+Validation: deterministic tests cover delayed old head publication, interrupted
+segment recovery, competing segment writers, identical-content ETag ABA, reader
+races during append and owner replacement, pending deletion recovery, and v1
+compatibility. A real local MinIO campaign passed conditional owner replacement
+and rejection of the delayed writer, along with the earlier 72 MiB restoration,
+full-stream integrity and missing-history checks. The head remained bounded
+(517 bytes with pending deletion in that campaign). Hosted S3 and remote runner
+lifecycle qualification remain separate.
+
+The latest real hosted Codex/browser campaign,
+`local-2026-09-29T04-32-53-143Z`, passed its download/restart/continuation cell.
+It predates the remote conditional-publication additions, which have their own
+object-store qualifications. Full recursive typecheck and build passed before
+those additions; a subsequent server typecheck passed after conditional writes.
+The broad test campaign finished with 13,684 passed and five failures: its
+long-lived module cache used old implementation modules with tests edited during
+the run. Those five tests pass in fresh processes, but this mixed-source run is
+not a coherent final-candidate full-suite pass. Temporary test configurations
+were restored. A frozen-source full run remains required.

+
+## 23. Real-provider endurance workflow (2026-09-29)
+
+The manual `history-endurance` suite now runs ordinary browser requests against
+Paperclip, the native indexed runner, and the real Codex provider. Its short cell
+performs three turns on one task/session. Its elapsed-time cell performs 73 turns
+at hourly intervals over 72 hours. Every turn runs a shell diagnostic, appends an
+exact reference to the same task document, and downloads both its new output and
+the first turn's output through the browser. The oracle checks byte length,
+digest, exact document contents, session identity, distinct successful runs,
+terminal task state, and absence of unintended child work or pending interactions.
+
+Scheduled controller restarts alternate graceful shutdown and SIGKILL of the
+isolated supervisor's exact owned controller process. They occur between settled
+turns; this is not qualification of a crash during an external effect. The harness
+accepts no arbitrary PID, signal, or command in a restart request. The elapsed
+cell has 12 restarts and no automatic retry. Idle browser polling, continuous
+video, and continuous tracing are disabled for this suite; per-turn screenshots,
+API snapshots, cost accounting, and partial observations remain available.
+
+Qualification:
+
+- 579 runner-E2E harness tests across 49 files and its TypeScript check passed.
+- The first smoke's workflow checks passed but campaign packaging failed because
+  the required API snapshot was absent. That attempt remains failed evidence.
+- After fixing snapshot packaging and waiting for the final task page to render,
+  the graceful-restart smoke passed as campaign
+  `local-2026-09-29T05-14-37-065Z`.
+- The frozen-build smoke with both graceful and hard restarts passed as campaign
+  `local-2026-09-29T05-22-09-264Z` in five minutes. All 20 checks passed, including
+  repeated browser download of the original 29,696-byte output after each
+  restart. The final screenshot was inspected and shows the completed task and
+  document revision 3.
+- The same frozen candidate began its actual 72-hour cell at approximately
+  05:29 UTC on September 29. It is **running, not a passing result**. Source and
+  binary provenance are recorded in
+  `/tmp/paperclip-journal-indexed-e2e-source-endurance-72h-1.json`; its log is
+  `/tmp/paperclip-journal-indexed-live-e2e-endurance-72h-1.log`. Later development
+  does not modify the frozen endurance worktree.
+
+These results do not enable default activation or satisfy unfinished migration,
+whole-session restoration, provider containment, hosted-provider, or elapsed-time
+gates.
+
+## 24. Remote checkpoint lifetime and controller capacity failures
+
+Checkpoint tar, hashing, and extraction now use an owned duplex command channel
+when a provider supports it. Only bounded completion metadata travels over that
+channel. The archive remains on private disk and crosses the transport in verified
+192 KiB chunks. This avoids the native bulk-sync archive cap and the provider's
+single-execution RPC deadline for history-sized commands. Existing generic
+workspace-upload guards remain in place. Providers without duplex support retain
+their legacy transport restrictions and are not qualified as unlimited.
+
+The focused transfer/executor run passed 481 tests across three files, including
+an actual loopback duplex round trip, credential/scratch exclusions, refusal to
+replace the prior good checkpoint with an unsafe archive, a >64 MiB archive and
+more than 20,000 entries. The server TypeScript check passed. These tests exercise
+real tar/streaming subprocesses but do not establish hosted-provider performance.
+
+PostgreSQL machine-readable capacity errors and local ENOSPC/EDQUOT now produce
+`storage_pressure`. The controller permits retry through the same owner only
+when a fresh read proves the exact old generation and bytes are unchanged.
+Connection loss, read-only storage and shutdown remain `storage_unavailable`;
+unknown commit outcomes remain fenced. Error messages are not parsed as proof.
+Nineteen focused tests passed, including real PostgreSQL transactions with
+injected SQLSTATE 53100 before and after writes, exact rollback of receipts and
+cursors, and a subsequent successful mutation through the same controller. This
+is database fault injection, not a claim that the PostgreSQL disk was filled.
+
+## 25. Bounded asynchronous transport admission
+
+The durable controller's mutation queue does not by itself bound incoming frames:
+frames can wait in a promise chain before reaching a mutation. Admission now
+accounts for both frames and bytes before retaining that closure. Connections
+pause reads at 16 frames or 4 MiB and resume after draining below the low watermark.
+Hard per-connection and per-authority budgets close a peer that cannot respect
+backpressure; its unacknowledged records replay from durable storage. Completed
+processing returns all admission credit, independently of total historical work.
+
+The raw socket parser stops consuming its buffered suffix while paused. Outbound
+provider WebSockets keep a bounded already-received suffix, including frames
+received before listener attachment. Both transports bound pending output to a
+slow peer as well. Already admitted work remains part of the existing explicit
+retirement drain. Qualification for this change is recorded after its focused
+real-socket and encrypted-protocol checks; it is not part of the older frozen
+72-hour candidate.
+
+The bounded-ingress qualification passed 99 runner transport tests and nine
+server WebSocket tests, including real encrypted traffic blocked on a durable
+commit and then drained in order on the same connection. The runner package
+build (including Rust and contract parity) and server typecheck passed. These
+checks cover admission and buffering; they do not replace the elapsed soak.
+
+## 26. Recovery while a real tool is running
+
+The explicit `history-endurance.runner-codex.local.active-restart` fixture
+requests two real Codex turns. It crashes only its owned controller after public
+events show the unique diagnostic shell command running, requires completion
+of that same tool execution on that same run after the crash, then requires
+a second successful turn on the original provider session and exact original
+output download. The fixture rejects extra runs, replacement tool identities,
+failed exit codes, and missing output. Its fixed `sleep 45` exposes the crash
+boundary; it does not alter production timeouts.
+
+The credential-free E2E harness passed 581 tests in 50 files and typechecked.
+The first live execution is in progress; no active-tool recovery pass is claimed
+yet. The frozen multi-day candidate remains unchanged.
+
+The first live active-tool crash attempt completed the original run but failed
+the exact output oracle: the provider completion contained 993 repetitions of
+the diagnostic rather than 1,024 (28,797 versus 29,696 bytes). That failed result
+is retained in campaign `local-2026-09-29T05-53-05-814Z`; a successful run status
+is insufficient evidence. A diagnostic attempt using the same burst of 1,024
+shell writes passed all 15 checks in campaign
+`local-2026-09-29T06-00-46-176Z`: same execution across SIGKILL, same provider
+session for the continuation, and exact first/second browser downloads. Private
+provider-frame inspection on that passing attempt confirmed 450 incremental
+command-output notifications totaling exactly 29,696 bytes, matching the final
+provider snapshot. Raw traces remain outside the published report.
+
+That inspection exposed a separate Paperclip omission: the Rust normalizer
+ignored `item/commandExecution/outputDelta`. The indexed path now retains these
+as command-output deltas, with an external body for large admitted frames. The
+TypeScript facade preserves their execution identity and channel. It does not
+relabel shell output as assistant prose. Two focused Rust tests and 165 facade
+tests passed; the E2E harness passed 583 tests. The endurance oracle now also
+requires the independent stream's exact digest, byte count, and execution ID.
+
+The stronger live attempt (`local-2026-09-29T06-09-01-643Z`) retained 436 deltas,
+but both the complete stream and provider completion contained only 26,651
+bytes and the same SHA-256. It failed the unchanged expected-output check.
+This does not establish lossless generated stdout at the provider boundary.
+The next fixture emits the same 29,696 bytes with one shell write after the same
+45-second delay, removing the burst of tiny writes while preserving the crash,
+stream, continuation, and browser-download assertions. Earlier frozen endurance
+fixtures remain unchanged; their results belong to their own definition hashes.
+
+## 27. Storage pressure with a disconnected control socket
+
+Storage retries now distinguish an unavailable socket from invalid protocol or
+authentication. A brief disconnect preserves the exact write/effect stack only
+while its already-authenticated lease and execution deadline remain valid.
+When capacity returns, the ordinary loop reconnects with the retained credential
+and delivers the original durable result. No new effect is admitted during the
+wait. Expiry, explicit stop, revocation, and invalid frames still stop the owned
+execution without fabricating a successful receipt.
+
+Seven encrypted-transport/real-SQLite pressure tests passed, including reconnect
+after actual `SQLITE_FULL`, exactly one effect, stop/revocation while full, and
+expiry while disconnected. The initial parallel run passed five and timed out
+two existing connected-renewal cases; the isolated case and complete repeated
+set passed. A broader Rust suite and updated production build are running;
+those are not yet reported as passing.
+
+## 28. Broad-test diagnosis and active-command crash qualification
+
+The coherent frozen source-5 qualification completed: recursive build and
+typecheck passed; the full suite had 13,689 passing tests, six failing tests and
+74 skips (709 passing files, two failing files, six skipped). Five failures were
+chat-control freshness assertions; rerunning their containing cases against the
+same frozen source passed all 26 selected tests. This does not erase the full
+run's failures or establish that their timing behavior is fixed. The sixth was
+the new >64 MiB / 20,100-entry checkpoint test reaching its 240-second deadline.
+Extraction now syncs files in bounded groups of eight, awaits every result, and
+syncs the directory afterward. The unchanged byte/count oracle and checkpoint
+command tests pass (six tests, 145 seconds including setup).
+
+The full Rust run exposed pressure-fixture timing errors: a four-second test
+lease expired under parallel synchronous writes, and the controller reused the
+short authentication timeout while awaiting runtime messages. The fixture now
+uses a bounded execution deadline for runtime reads, a 30-second lease for
+recovery cases, and the original four-second lease for intentional expiry. Its
+reconnect accept is bounded, so early runner failure cannot hang the test. An
+intermediate timeout-loop mistake was also caught and corrected; failed runs
+15–17 remain recorded. Full Rust run 18 passed, including all seven pressure
+cases and 332 library tests (one ignored). This run predates the native
+inspection addition below. Logs: `/tmp/paperclip-unbounded-rust-18.log`,
+`/tmp/paperclip-pressure-disconnect-rust-3.log`,
+`/tmp/paperclip-checkpoint-bounded-sync-tests-1.log`, and
+`/tmp/paperclip-chat-routing-frozen-5.log`.
+
+Live campaign `local-2026-09-29T06-24-27-447Z`, active-restart attempt 4,
+passed all 15 checks in 4.8 minutes. The controller received SIGKILL during
+execution `exec-29e2fdfe-64a5-4d75-807e-eabf053417fd` in run
+`f3f16635-3470-40bc-9e0a-3bb046c3e945`: start event 39, completion event 85,
+exit zero after restart. The next browser request completed in run
+`80001cdc-5367-4d18-ad9d-401a1ec75841`, retaining the same provider session.
+The first diagnostic's streamed bytes,
+completion body and original browser download all contain exactly 29,696 bytes,
+SHA-256 `f89dabb3c09ca859f2e0cc8d856f88660ae5f9f5ce42c785243edcb40ab13e7d`.
+The final browser screenshot was visually inspected. Source/binary provenance:
+`/tmp/paperclip-journal-indexed-e2e-source-active-restart-4.json`; exact evidence
+is in the campaign's `snapshots/history-endurance.json` and
+`snapshots/active-restart.json`. The single-write fixture passes; prior
+burst-output failures remain unresolved provider/transport diagnostics and
+are not reclassified as passes. The frozen 72-hour real-provider campaign has
+completed two hourly turns and is still running, not qualified as a pass.
+
+## 29. Native read-only inspection for remote indexed authority
+
+`paperclip-runnerd storage inspect-state --path <locator>` reads exactly the
+current runner/provider row using the bundled native SQLite engine, a shared
+store lifetime fence, a read-only transaction and digest/generation checks. It
+does not recover a prepared commit, enumerate receipts, or checkpoint the WAL.
+Incomplete imports/backups, changed bindings, malformed cursors and conflicting
+redo fail closed. An undelivered outbox is represented by a negative pending
+fence rather than loaded as historical output. The snapshot has an exact decimal
+generation and is streamed as ordered 192 KiB chunks with an overall length,
+digest and required completion footer.
+
+Remote runtime inspection, provider checkpoint inspection and reattachment now
+resolve an indexed locator through this command and an owned duplex channel.
+The decoder bounds individual frames and total *current-state* bytes, verifies
+sequence/digest/clean exit, and closes its owned channel on every outcome.
+Remote fresh indexed activation remains disabled pending the full remote
+archive/backup and provider qualification; this adds a recovery primitive, not
+a claim that hosted execution is qualified.
+
+Four native inspection tests pass, including conflicting-redo rejection without
+repair and a multi-frame Unicode snapshot. Eleven server inspection tests pass,
+including the actual native binary reading a live WAL database through the
+duplex transport, a generation above JavaScript's exact integer range, and
+corruption/truncation/timeout rejection. The initial ten decoder tests and all
+475 executor tests passed together; server typecheck passed before the final
+remote checkpoint call-site addition. Logs:
+`/tmp/paperclip-native-inspection-rust-2.log`,
+`/tmp/paperclip-native-inspection-real-server-tests-1.log`,
+`/tmp/paperclip-native-inspection-server-tests-1.log`, and
+`/tmp/paperclip-native-inspection-typecheck-1.log`.
+
+
+## 30. Consistent native session snapshots (2026-09-29)
+
+Added `storage snapshot-session` and a remote checkpoint consumer. The native
+operation owns exclusive lifetime fences for both the runner and Codex provider
+stores, validates exact generations/digests and a settled session binding, and
+uses the existing resumable partition backup with explicit portable database
+filenames. An append-only request and assembly marker let a retry finish a
+partial copy or directory publication. Original state, locators and receipts
+remain authoritative until the completed snapshot is published. Existing
+single-store backups keep their `authority.sqlite` layout.
+
+The published artifact contains both current states and all exact receipts,
+including partitions relocated away from the runner directory. A background
+verification streams every receipt and checks its key, digest, range count,
+accounted storage bytes and aggregate fingerprint. It rejects missing, corrupt,
+external or incomplete partitions; ordinary inspection/resume does not invoke
+this history scan. The server transfers the verified snapshot over the owned
+checkpoint channel and removes its two exact remote job directories only after
+the host backup has been durably published. Interrupted transfers retain their
+native snapshot for retry.
+
+Qualification and failures remain distinct:
+
+- Full Rust run 19 passed before this snapshot implementation (including the
+  native inspection addition); log `/tmp/paperclip-unbounded-rust-19.log`.
+- Frozen source 5 is preserved in
+  `/tmp/paperclip-unbounded-frozen-source-5.tar.gz`. Source 6 has 7,934 files and
+  diff SHA-256 `30e44bc6dc296557e9143906d66bd456dd685b79f27e27c83121bda63b35e62a`.
+  Its build passed. Recursive typecheck found Rust formatting differences;
+  those are corrected in the working copy. Its full tests are running against
+  the unchanged source, with provenance and configuration restoration retained.
+  This is not a green whole-repository result.
+- Snapshot unit run 1 exposed a test-path assertion that compared macOS's `/var`
+  alias with the canonical `/private/var` relocation path. Run 2 passed four
+  tests, including all copy/publication interruptions and relocation-volume
+  loss; `/tmp/paperclip-native-session-snapshot-tests-2.log`.
+- A real child-process SIGKILL after a durable partial receipt copy passed,
+  resumed the same job, removed the source stores, and recovered exact old
+  receipts from both snapshots:
+  `/tmp/paperclip-native-session-snapshot-crash-tests-1.log`. That run preceded
+  the additional full-receipt verification pass.
+- Real server duplex snapshot/transfer/source-loss/receipt-reopen tests passed
+  (two tests, `/tmp/paperclip-native-session-snapshot-server-tests-4.log`).
+  Earlier attempts used an overbroad test RPC stub, then used the
+  controller-only proof-receipt endpoint for a runner receipt; both fixture
+  errors were corrected without changing the byte-preservation oracle.
+- Full-receipt verification initially compared body bytes with stored accounting
+  bytes (which also include key and row overhead). Snapshot run 3 and server
+  run 5 caught that mismatch. The verifier now uses the same accounting as the
+  receipt writer; final qualification is recorded below when complete.
+- Full Rust run 20 caught a completed-snapshot retry creating lock files in an
+  unrelated empty destination before rejecting it. Verification now requires
+  existing lifetime fences and leaves a conflicting destination untouched.
+  Fixed-source run 21 passed the full Rust suite, release build, 488 server
+  tests and server typecheck. All source hashes remained unchanged;
+  `/tmp/paperclip-native-session-snapshot-qualified-source-21.json`.
+- Run 22 additionally qualifies immutable published files and outer manifest
+  bindings: full Rust suite (including the real SIGKILL copy/restart test),
+  release build, 489 server tests and server typecheck passed. The source hash
+  check passed; `/tmp/paperclip-native-session-snapshot-qualified-source-22.json`.
+  Tests include repeated non-mutating backup verification, changed generations,
+  missing native markers, all copy/seal/publication interruptions and exact
+  receipt restoration after source loss. Logs are
+  `/tmp/paperclip-unbounded-rust-22.log`,
+  `/tmp/paperclip-native-session-snapshot-server-tests-8.log` and
+  `/tmp/paperclip-native-session-snapshot-typecheck-4.log`.
+
+This closes the raw-SQLite-copy gap for the native snapshot component. It does
+not yet qualify a whole-session recovery generation spanning Postgres, external
+payloads, both native stores and provider files. Remote and other-provider
+activation, production retained migration admission, full process retirement,
+lifetime cursor rollover, and the elapsed-time gates remain open. Fresh indexed
+activation stays opt-in.
+
+## 31. Database snapshot boundary for coordinated backup (2026-09-29)
+
+The existing JavaScript database exporter did not share a read snapshot across
+its catalog, table and COPY reads. It now runs those reads in one repeatable-read,
+read-only transaction using bounded row cursors. Row counts use
+exact decimal text rather than a signed 32-bit cast.
+
+`withDatabaseBackupSnapshot` owns an exported PostgreSQL snapshot while its
+callback reads current authority and invokes a background exporter. Both native
+`pg_dump` and the JavaScript exporter accept that exact `snapshotId`; an expired
+or malformed snapshot must fail rather than silently use a newer database
+point. The exporting transaction remains alive for the callback, then closes
+on success or failure. The full history export stays outside execution
+transactions and ordinary continuation.
+
+Qualification run 1 caught a COPY stream stalling before its transaction's next
+statement. Filtered JavaScript exports now use the existing bounded row cursor
+as well. Runs 2 and 3 pass all 12 backup tests against isolated PostgreSQL 17,
+including actual native `pg_dump`/`psql`, concurrent authority/receipt mutations,
+large table payloads and exact restored generations beyond JavaScript's integer
+range. Run 3 also tests expired snapshots through native export and automatic
+fallback; neither may publish a newer database point. Database typecheck and
+source hashes passed. Logs: `/tmp/paperclip-db-backup-snapshot-tests-3.log`,
+`/tmp/paperclip-db-backup-snapshot-typecheck-2.log`; provenance:
+`/tmp/paperclip-db-backup-snapshot-qualified-source-3.json`.
+
+This supplies the database component; it does not yet connect a full
+controller/native/provider/payload recovery coordinator or qualify a complete
+volume-loss restore. PostgreSQL's [snapshot import rules](https://www.postgresql.org/docs/current/sql-set-transaction.html)
+and [pg_dump snapshot option](https://www.postgresql.org/docs/current/app-pgdump.html)
+define the database boundary.
+
+## 32. Fenced local inspection and current validation (2026-09-29)
+
+Local inspection now runs the qualified native `storage inspect-state` command,
+including its shared store-lifetime fence. A bounded worker decodes the streamed
+frames off the API event loop, with at most one unconsumed pipe chunk. The parent
+owns and reaps the native child on malformed output, timeout or cancellation;
+reader capacity is released only after that child closes. Local and remote
+inspection share the exact length, digest, generation and footer decoder.
+Migration publishes both lifetime and operation fence files with each native
+store. Readers never create a missing lifetime fence as evidence of ownership.
+
+Focused reader/migration/archive tests, including a large Unicode current state,
+malformed multi-megabyte output and child cleanup, pass. Runner and server
+TypeScript checks pass. The full Runner TypeScript run 14 failed five storage
+cases; run 15 failed one receipt-completion wait. Fixture deadlines now allow
+parallel durable I/O without changing receipt assertions or production policy.
+Run 16 passes 2,139 tests in 161 files, with 14 tests in five qualification files
+skipped. Non-Rust source and the exact native binary were unchanged during that
+run: `/tmp/paperclip-native-local-reader-qualified-source-6.json` and
+`/tmp/paperclip-unbounded-runner-tests-16.log`.
+
+Live active-restart attempt 5 remains failed: the interrupted first command's
+29,696 bytes survived, but the following fast command had a complete body and
+zero recorded command-output deltas. The fixture now explicitly requests an
+asynchronous shell invocation and delays ordinary diagnostics three seconds;
+the interrupted command retains its 45-second delay. Stream assertions were
+not weakened. Attempt 6 passes all 15 checks, exact streamed/completed/browser
+output bytes in both turns, the active-command crash, and same-session
+continuation. Campaign: `local-2026-09-29T08-38-23-764Z`; its final task screenshot
+was inspected. Provenance: `/tmp/paperclip-journal-indexed-e2e-source-active-restart-6.json`.
+This run uses the qualified source-22 native artifact and the newer TypeScript
+reader. It does not qualify the subsequent ACPX native changes or reclassify the
+prior small-write burst losses.
+
+Retired harness backup cleanup is also asynchronous and uses the existing
+external directory-name sorter. It no longer builds a directory-sized array or
+blocks the API event loop through a synchronous recursive delete. The existing
+128-level backup path contract still applies; file count has no aggregate bound.
+The immutable-directory/symlink test and a 4,097-file cleanup test pass. The
+related server run passes 483 tests and server typecheck:
+`/tmp/paperclip-native-backup-cleanup-server-tests-2.log` and
+`/tmp/paperclip-native-backup-cleanup-typecheck-1.log`.
+
+## 33. Indexed ACPX receipt implementation (2026-09-29, qualification pending)
+
+The ACPX session now has an opt-in indexed receipt ledger. Each admitted
+`durability.indexed_state.v1` run keeps its current reducer, pending tool calls,
+a single unacknowledged event batch and any uncertain tool-result delivery in
+bounded current state. Completed dynamic and reserved tool receipts move into
+separate exact indexed namespaces, scoped to run and turn. A settled-turn index
+rejects ancient turn reuse after the in-memory ledger rotates. Receipt keys are
+never probabilistic summaries.
+
+A provider event batch and its receipt changes commit before the caller can
+observe them. The executor saves the projected outbox and the batch identity
+before acknowledging that batch. Tool results commit their exact receipt and
+delivery intent before the sidecar receives `tool.resolve`; acknowledgement then
+clears that intent. Unacknowledged batches, active turns and uncertain deliveries
+hold replacement admission rather than being discarded on reopen. This does not
+yet implement automatic recovery of those held ACPX lifetimes, and production
+fresh-session activation remains local Codex only.
+
+Three focused fault tests pass: no replacement spawn with an unacknowledged
+batch, preservation of an unconfirmed result, and no provider delivery when a
+real SQLite checkpoint transaction is rejected. The initial test run also had a
+fixture validation failure and a SIGBUS crash. Full Rust run 23 reproduced the
+crash in an isolated build, disproving the initial rebuilt-artifact hypothesis.
+Neither run is passing qualification. Native builds use
+`runner/target/history-development` to preserve artifacts used by the previously
+started endurance processes.
+
+The regression suite runs 64 calls by default. The separate qualification uses
+`PAPERCLIP_ACPX_RECEIPT_QUALIFICATION=4200` to cross the former 4,096-call ceiling
+with exactly the same byte and replay assertions. Current state is measured
+against the initial tool-catalog checkpoint; the limit is initial size plus
+4 KiB, independent of completed call count.
+
+
+## 34. SQLite descriptor ownership and recovery admission (2026-09-29)
+
+The long ACPX qualification exposed a real SIGBUS in SQLite's WAL index, repeated
+in an isolated build. Preflight checks opened and closed the database and SHM
+files outside SQLite. On POSIX this can cancel every advisory lock held by the
+process for that file, including SQLite's dead-man switch; a separate reader can
+then truncate SHM under a live writer. The fix uses metadata-only checks before
+SQLite's own NOFOLLOW open and never probes those files with a separate file
+descriptor. Snapshot sealing closes SQLite before opening its final fsync handle.
+See [SQLite's documented descriptor hazard](https://www.sqlite.org/howtocorrupt.html#posix_advisory_locks_canceled_by_a_separate_thread_doing_close_)
+and [WAL shared-memory locking](https://www.sqlite.org/walformat.html).
+
+The new regression performs commits while opening a second same-process store,
+reading exact receipts and repeatedly launching an external SQLite reader. The
+writer runs in a subprocess so a regression reports a failed test rather than
+losing the entire suite. Initial fixture attempts failed on an unsupported
+unsigned SQLite decode and macOS's `/var` symlink under NOFOLLOW; the corrected
+regression and all four ACPX tests pass in
+`/tmp/paperclip-indexed-sqlite-locks-acpx-tests-4.log`. Full native run 24 passes
+(`/tmp/paperclip-unbounded-rust-24.log`). The explicit 4,200-call lane also passes
+in 426.15 seconds: current state starts at 36,686 bytes and peaks at 36,690 bytes,
+with the original provider PID unchanged and exact ancient receipt/turn replay
+checks passing (`/tmp/paperclip-acpx-indexed-4200-tests-5.log`). Source 24 is
+preserved in `/tmp/paperclip-native-lock-fix-source-24.tar.gz` with the 78-file
+hash manifest `/tmp/paperclip-native-lock-fix-qualified-source-24.json`. These
+passes qualify the lock fix; they precede the subsequent outbox-failure guard.
+
+Read-only indexed projections must not authorize legacy destructive maintenance.
+The executor now refuses indexed current state in PID-only stopped-session
+cleanup and quiescent recovery. An actual indexed process-tree admission is
+still required; absence of individual PIDs or a process group cannot establish
+that escaped descendants have stopped. Regression coverage includes both Codex
+and ACPX cleanup and the cold recovery path. All 478 executor tests pass in
+`/tmp/paperclip-native-indexed-recovery-gate-tests-1.log`. Server typecheck also
+passes (`/tmp/paperclip-native-indexed-recovery-gate-typecheck-1.log`). Directory-emptiness
+checks now read one entry rather than allocating the directory's full history.
+
+
+The ACPX executor must additionally distinguish an in-memory projected batch
+from its successful outbox publication. If the indexed provider checkpoint
+write fails, the writer now retains a sticky persistence error: later polls,
+drains and acknowledgements cannot publish or release that candidate. Shutdown
+still reaps its owned provider but cannot claim successful durable retirement.
+A regression injects an actual rename failure after syncing the candidate,
+restores the filesystem and checks that retry cannot acknowledge the unpublished
+batch. All 14 backend tests pass, including this injected publication failure:
+`/tmp/paperclip-acpx-indexed-outbox-failure-tests-1.log`. Full Rust run 25 and
+its release build are running. Binary staging now honors `CARGO_TARGET_DIR`,
+so staging an isolated build cannot silently select an older default artifact.
+
+
+## 35. Fixed-source qualification and suspension admission (2026-09-29)
+
+Full native run 25 and its release build pass, including the SQLite descriptor
+regression, session snapshot/source-loss tests and ACPX failed-publication guard.
+Native source hashes stayed fixed for the run:
+`/tmp/paperclip-native-outbox-qualified-source-25.json` and
+`/tmp/paperclip-unbounded-rust-25.log`. The default and isolated release runner
+binaries were byte-identical before staging. macOS staging now specifies the
+stable signing identifier `paperclip-runnerd`; the previous random temporary
+filename changed the signed artifact on every stage. Repeated staging produces
+identical bytes and passes `codesign --verify --strict`:
+`/tmp/paperclip-native-staging-repeatability-26.json`.
+
+An additional recovery restriction initially rejected ordinary, successfully
+committed indexed suspension. Live active-restart attempt 7 therefore failed its
+second turn with `runner_state_identity_mismatch`. This was a product regression,
+not an infrastructure failure. The corrected admission preserves the runner's
+existing committed-suspension protocol while rejecting legacy PID-only indexed
+cleanup, invented quiescence, and dead-runner warm-transition recovery. All 480
+executor tests pass in
+`/tmp/paperclip-native-indexed-recovery-gate-tests-4.log`.
+
+Active-restart attempt 8 passes all 15 matchers. Two real Codex turns retain the
+same provider session, the exact old and new tool-output downloads, and the
+ordered task document. The first diagnostic survives a forced **controller**
+crash in the same run. This does not kill the native runner or provider and does
+not prove automatic recovery from either one's death. The final browser screen
+was inspected and shows the completed task and two-line ledger. Campaign:
+`local-2026-09-29T09-30-19-234Z`; provenance:
+`/tmp/paperclip-journal-indexed-e2e-source-active-restart-8.json`.
+
+Full Runner TypeScript run 17 failed one tiny-partition fixture deadline under
+parallel I/O. Its assertions and production limits were unchanged; the fixture
+now allows 60 seconds. Run 18 passes 2,139 tests in 161 files, with 14 tests in
+five separate qualification files skipped:
+`/tmp/paperclip-unbounded-runner-tests-18.log`. All 7,944 source-file hashes and
+four native artifact hashes remained unchanged throughout run 18 and live
+attempt 8. The source is preserved in `/tmp/paperclip-unbounded-source-26.tar.gz`
+and `/tmp/paperclip-unbounded-source-26.json`. Subsequent documentation edits do
+not extend that immutable-source claim.
+
+The 10 GiB full-pipeline qualification also completed successfully. It persisted
+409,622 events and 40,960 history items, 10,737,418,240 body bytes and
+11,406,679,685 normalized bytes. Physical storage was 39,117,692,297 bytes in 262
+files; peak current state was 1,146,649 bytes and final current states were
+37,293 / 1,954 / 23,515 bytes. Current-state resume took 54.86 ms, and same-runner,
+same-provider warm continuation took 2,039.57 ms. Total runtime was about 9.05
+hours. Logs and provenance: `/tmp/paperclip-history-pipeline-10gib.json`,
+`/tmp/paperclip-history-pipeline-10gib.log`,
+`/tmp/paperclip-history-pipeline-10gib-source.json`. This job began on older source
+and uses synthetic agent-message output; the working source changed while it
+ran. It is evidence for that storage workload, not immutable qualification of
+the latest mixed-output or ACPX implementation.
+
+The real and synthetic 72-hour jobs remain in progress. Full repository run 6
+also remains in progress on its separately frozen earlier source. These are not
+passing gates. Whole-session coordinated recovery generations, safe process-tree
+retirement after ambiguous crashes, production migration admission, remote and
+other-provider activation, and lifetime cursor rotation remain open. Fresh
+indexed activation remains opt-in.
+
+
+## 36. Physical database exhaustion and browser history admission (2026-09-29)
+
+Latest source-26 build and recursive typecheck both pass. Native artifact hashes
+remain identical after both commands. Logs: `/tmp/paperclip-unbounded-build-26.log`
+and `/tmp/paperclip-unbounded-typecheck-26.log`.
+
+The separate opt-in PostgreSQL capacity lane now exhausts an actual 16 MiB tmpfs
+tablespace in an isolated PostgreSQL 17 container. A real receipt relation
+extension fails after updating current authority. The transaction preserves the
+prior generation/current bytes and leaves no receipt. Releasing physical space
+allows the exact transaction to succeed. A second case exercises the live
+controller's in-memory rollback and subsequent bootstrap publication through the
+same controller. The database logs confirm actual ENOSPC; there is no injected
+SQL exception. Run 1 failed due to a test cleanup import typo; its exact owned
+container was removed after the failure. Run 2 and server typecheck pass:
+`/tmp/paperclip-history-pg-capacity-2.json`,
+`/tmp/paperclip-history-pg-capacity-2.log`,
+`/tmp/paperclip-history-pg-capacity-typecheck-2.log`.
+This qualifies tablespace exhaustion with WAL on a separate available filesystem;
+it does not claim qualification of a full WAL device or provider filesystem.
+
+The frozen hosted-provider 72-hour attempt has exposed a browser history failure:
+at 09:30:31 UTC on September 29, concurrent old-run log requests received
+`500 run_log_storage_pressure`. The task page legitimately asks for several
+retained logs at once, while the segment verifier rejected its third concurrent
+read. This is a product failure in that attempt, even though later model turns
+may continue. Its source and result evidence remain unchanged.
+
+The current reader now admits two active verifications and a FIFO of at most 64
+small waiting descriptors. Queued reads allocate no segment bodies and return
+credits on success or failure. A queue overload/expiry returns HTTP 429 rather
+than an internal error. An old remote tail can refresh using its existing credit;
+it never waits for a queued replacement read that needs that same credit.
+Twenty-seven log-store tests pass, including twelve simultaneous histories,
+failure credit release, bounded overload and two concurrent retired-tail
+refreshes with newer reads waiting:
+`/tmp/paperclip-history-log-read-queue-tests-1.log`. Server typecheck passes.
+
+History-endurance grading version 4 now fails on browser run-log HTTP errors and
+retains only bounded public fixture run IDs/status codes as evidence. It cannot
+mark a task's history healthy solely because its original and latest downloads
+succeeded. All 584 E2E unit tests and E2E typecheck pass:
+`/tmp/paperclip-history-endurance-unit-7.log` and
+`/tmp/paperclip-history-endurance-typecheck-7.log`. This new criterion is not
+retroactively applied to relabel the old campaign's machine result.
+
+
+## 37. Near-term output counter and retained-history oracle correction (2026-09-29)
+
+Source 27 is archived with 7,946 source hashes and four artifact hashes in
+`/tmp/paperclip-unbounded-source-27.json` and `.tar.gz`. Its build passes
+(`/tmp/paperclip-unbounded-build-27.log`), and 41 related server tests pass in
+`/tmp/paperclip-history-log-read-server-tests-2.log`.
+
+The first three-turn rerun with the new history HTTP criterion failed after two
+otherwise successful turns: it counted a new run's temporary pre-output 404 as
+lost retained history. This was an overbroad fixture oracle. Campaign
+`local-2026-09-29T09-56-12-486Z` remains failed. The collector now watches only runs
+already completed and independently byte-verified by the fixture. All 404, 429
+and 500 responses for those retained runs still fail; tests distinguish them
+from a new run without its first log. E2E unit run 8 passes 585 tests in 50 files,
+and E2E typecheck passes. This correction does not excuse the old frozen
+endurance attempt's 500 errors for previously completed runs.
+
+The counter audit found `heartbeat_runs.last_output_seq` still used a signed
+32-bit integer, unlike the existing bigint event cursors. Generated migration
+0291 widens this output-progress field to bigint without changing its numeric
+API representation. The physical PostgreSQL lane also crosses 2,147,483,647 and
+reads back exactly 2,147,483,648. This removes the nearer output-count ceiling;
+it does not implement the lifetime epoch transitions in the target contract.
+
+## 38. Retained-history browser proof and opaque controller revisions (2026-09-29)
+
+Source 28 (`/tmp/paperclip-unbounded-source-28.json` and matching archive)
+passed the corrected three-turn real browser/Codex smoke campaign
+`local-2026-09-29T10-02-54-095Z`. All three turns retained the provider session
+through graceful and forced between-turn controller restarts; original and
+current tool output downloaded byte-for-byte, and retained-history HTTP requests
+succeeded. The final browser screenshot was inspected. The result and snapshots
+are under `tests/runner-e2e/results/<campaign>/history-endurance/runner-codex/local/smoke/attempt-1/`.
+Build 28 and repository typecheck 28 passed; the source and native artifact
+hashes were unchanged after those checks and the browser run. This is a short
+continuation proof, not an elapsed 72-hour result.
+
+The PostgreSQL controller authority now commits opaque revision identities and
+the exact predecessor atomically. Generated migration `0292_rainy_leader` retains
+legacy decimals and removes the lifetime signed-64-bit increment. A real
+PostgreSQL test seeds the old maximum, performs two more commits in the same
+run/session, reopens the store, reads the earliest exact receipt, and rejects
+both stale revisions. Legacy activation requires the immediate predecessor,
+including when the new revision is opaque. Native revisions and transport
+sequences still have separate work remaining; this does not claim their
+rotation is implemented.
+
+Focused verification after the revision change: 19 coordinator tests on isolated
+Docker PostgreSQL 17, 20 shared revision/SQLite/migration tests, and the physical
+PostgreSQL ENOSPC qualification all passed. Logs:
+`/tmp/paperclip-history-opaque-revision-postgres-1.log`,
+`/tmp/paperclip-history-opaque-revision-runner-1.log`, and
+`/tmp/paperclip-history-pg-capacity-4.log` (report `.json`). The latter again proves
+rollback and same-controller retry after real tablespace exhaustion, plus output
+progress beyond signed 32-bit. Repository typecheck 29 passed. Full recovery,
+production migration admission, remote activation, lifetime cursor rotation and
+the coherent final qualification matrix remain open.
+
+## 39. Native revision boundaries and end-to-end controller revision proof (2026-09-29)
+
+The source-29 browser campaign `local-2026-09-29T10-22-19-988Z` passed all 21
+checks in 203,316 ms with three real Codex turns, the same provider session,
+graceful/hard controller restarts and exact old/new browser downloads. It used
+the PostgreSQL opaque revisions and the prebuilt native-25 binary. Native source
+edits began after the campaign had built its binary; TypeScript edits resumed
+after the campaign finished. Its final screenshot was inspected. Logs and
+provenance use the `smoke-opaque-revision-1` suffix under `/tmp`.
+
+Native SQLite current-state revisions now have an explicit type: absent, exact
+legacy integer, opaque UUID identity, or fenced writer. At the former signed-64-bit
+maximum they switch permanently to opaque identities. Receipt order remains
+independent. The root redo transaction stores an exact predecessor and a v2
+commit fingerprint; retries of an old v1 fingerprint remain valid. Current-state
+inspection, proof reads, archive/seal, backup and both provider ledgers use exact
+equality. The predecessor is bounded metadata on one current commit row, never
+a retained list. Opening a retained store adds its nullable predecessor column;
+older binaries do not support writing this revised format and must not be used
+for downgrade recovery.
+
+Boundary tests cover prepare-before-leaf/reply interruption, stale writers,
+changed retry content/predecessor, old commit-stamp upgrade, exact ancient
+receipt reads, current owner pages, archive movement and two-store source-loss
+restore. The Node proof-reader preflight also uses metadata only: probing and
+closing SQLite descriptors could cancel another worker's POSIX locks. The
+unchanged old `indexed-local-state-worker.ts` is retained for the running older
+endurance jobs; new production reads use the owned native reader.
+
+Focused native verification: 39 passed, one explicitly skipped 100,000-call
+qualification (`/tmp/paperclip-native-opaque-revision-tests-2.log`). The first
+TypeScript boundary run failed two sealing checks because that caller still
+required decimal revisions; the caller and native archive-intent reader were
+fixed. The corrected cross-language store/proof/seal/migration run passed all
+15 tests (`/tmp/paperclip-history-opaque-revision-runner-3.log`). Typecheck 30
+passed before the final reader correction; a later complete check is still
+required.
+
+Full Rust 30 failed the unchanged verified-launch test's one-second first-line
+wait (no first line arrived). An isolated rerun passed in 0.22 seconds. The
+identity assertion is unchanged; its initial startup allowance is now five
+seconds because this is not a startup-performance test. Full Rust 31 is running
+against the final native revision code. Rust 30 remains a failed attempt.
+Transport/event/log cursor epochs, provider lifecycle ordinals and the other
+full-contract gates remain independent and unfinished.
+
+
+Source 31 qualification completed: full Rust suite, repository build, and
+repository typecheck passed. Source archive `/tmp/paperclip-unbounded-source-31`
+contains 7,950 files plus hashes for five native artifacts; all source and
+artifact hashes were unchanged after the browser campaign. Actual local Codex
+active-continuation campaign `local-2026-09-29T10-46-03-379Z` passed all 16
+matchers in 227,475 ms. It used the isolated native-31 release binary, killed
+the controller during the active turn, continued the same provider session, and
+verified both turns' output through browser/public APIs. The final screenshot
+was inspected. This qualifies controller crash recovery, not an ambiguous
+runner/provider crash. Logs use the `active-restart-native-revisions-1` suffix.
+
+## 40. Unordered driver receipts
+
+Effects are immutable records addressed by semantic identity; no operation
+pages them by a global sequence. New native-backed SQLite and PostgreSQL stores
+now advertise unordered effect receipts, represented by sequence zero. The
+controller drops its obsolete lifetime `driverReceiptSequence` when using that
+capability. Legacy positive effect sequences remain exact and immutable.
+Retained v1 SQLite files keep their original ordered format and explicitly
+reject zero effects until migration; their capability remains false.
+Migration `0293_dazzling_the_hood` removes only effects from the sequence
+uniqueness index, retaining company/session effect identity uniqueness and
+positive ordered command/event sequences. Boundary and rollback tests are
+running; this is independent of transport and run-log cursor rotation.
+
+
+Unordered effects verification passed: 119 runner tests across three files
+(`/tmp/paperclip-history-unordered-effects-runner-1.log`) and 20 real PostgreSQL
+coordinator tests (`/tmp/paperclip-history-unordered-effects-postgres-1.log`).
+The migration ran through the normal DB generator and real database setup.
+
+## 41. Non-ordering identities and encrypted connection renewal
+
+Normalized delivery revisions now use opaque equality identities. The writer
+captures reducer state when queued, then binds each commit to the exact revision
+returned by the preceding commit. A retained numeric revision at JavaScript's
+maximum can advance without changing event order. Boundary, queued-commit,
+stale-writer and driver recovery tests passed: 106 tests across four files in
+`/tmp/paperclip-history-delivery-revisions-1.log`.
+
+Native provider outbox event IDs now use UUID identities. Queue order remains
+in the bounded durable deque. The retained numeric upper bound validates old
+pending IDs but no longer increases or limits new admission. Trace associations
+use the appended bounded queue suffix. Native tests verify mixed old/new IDs at
+`u64::MAX`, reopen, exact pending order, unchanged active turn, and duplicate ID
+rejection. All 62 matching provider backend tests passed in
+`/tmp/paperclip-history-provider-event-identities-2.log`; attempt 1 had an incorrect
+Cargo package selector and ran no tests. Typecheck 32 stopped at Rust formatting
+after TypeScript succeeded; formatting is corrected, with a new check pending.
+
+Encrypted connections now renew before 1,048,576 frames per direction. New
+challenge-derived keys reset only connection-local nonce counters. Existing
+lease authentication and durable command/event reconciliation preserve work;
+this is not PRP delivery-epoch rotation. The controller supports a smaller
+interval for qualification but cannot raise the production bound. A real native
+runner plus credential-free provider test forces at least four authenticated
+connections during one active turn, verifies unchanged runner/provider PIDs,
+exact first-receipt lookup, and no interrupt/resume/repeated turn start. It passed
+in 3.38 seconds (`/tmp/paperclip-history-active-rekey-1.log`). The encrypted
+controller lost-ACK/old-replay tests and delivery tests passed 104 tests; the
+native nonce-boundary/old-ciphertext test passed separately. Logs use
+`paperclip-history-secure-rekey*` under `/tmp`. Native release 32 built and staged.
+
+
+Typecheck 33 passed after formatting. Connection and delivery envelope IDs now
+use UUIDs instead of deriving identity from diagnostic counts. Diagnostic
+totals saturate at the exact JSON integer maximum; saturation is a lower bound,
+never authority. The boundary test authenticates repeatedly, replays an early
+receipt, rejects malformed input, and reopens at the actual old maximum.
+The revised encrypted controller and active native test run passed all 102
+tests (`/tmp/paperclip-history-secure-rekey-2.log`).
+
+Codex JSON-RPC correlation now uses opaque string IDs in both native and direct
+Node transports. Runtime question identity uses a fresh random nonce, retaining
+the exact existing pending identity on duplicate input. Neither path increments
+a lifetime ordinal. The direct transport's 15 tests passed, including concurrent
+out-of-order response matching. Native attempt 1 failed five tests because its
+private shell JSON-RPC fixture replied with hardcoded IDs 1–4; the fixture now
+echoes the actual request ID, preserving all reader/exit assertions. Attempt 2
+and native transport settlement checks are recorded separately. Release 33
+built successfully before this test-only fixture correction.
+
+Native Codex request-identity attempt 2 passed all 24 tests in 55.88 seconds
+(`/tmp/paperclip-history-provider-request-identities-native-2.log`). The source
+now includes the corrected fixture; no production behavior changed in that
+correction.
+
+
+## 42. Source 34 qualification and failed attempts
+
+Source archive `/tmp/paperclip-unbounded-source-34` captured 7,952 source files
+and five native artifact hashes. Repository typecheck 34 passed. Full runner
+attempt 19 failed: 2,145 passed, 11 failed, 14 skipped. macOS power logs record
+a thermal-emergency sleep at 06:16:15 for 545 seconds and a maintenance sleep
+at 06:26:05 for 995 seconds (America/Chicago). Several observed timeout durations
+match these intervals. This is failed evidence, not a passing endurance run.
+The timed-out fixture also exposed a recursive test spy: transport fixtures now
+capture the original core opener once, rather than capturing another test's
+lingering spy. No production ACK change was made: the isolated goal ACK cases
+passed all three tests. Native rekey and transport settlement passed all 20
+checks across two files in `/tmp/paperclip-history-native-request-settlement-1.log`.
+
+Full Rust 34 failed one obsolete integration assertion: newly emitted provider
+IDs no longer advance the legacy integer counter. The corrected assertion
+checks the unchanged counter, three distinct exact IDs, one session-resumed
+event and two durable startup diagnostics. Targeted retry 2 passed; retry 1
+used an incorrect diagnostic event classification and is retained as failed.
+Logs are `/tmp/paperclip-unbounded-rust-34.log` and
+`/tmp/paperclip-history-provider-replay-identities-{1,2}.log`. Full qualification
+must be repeated on a fixed final candidate with reduced concurrency.
+
+
+## 43. Renewable command sequence namespaces
+
+Implemented negotiated `transport.command_epochs.v1` across native PRP,
+controller authority and PostgreSQL (generated migration 0294). The controller
+journals its exact intent before pausing command admission. The runner drains
+accepted commands, preserves semantic/provider work, commits the close receipt
+and successor head atomically, then returns that exact receipt. Reconnecting
+peers authenticate their command namespace and cursor; a peer lacking the
+capability cannot resume a rotated namespace. Legacy command fingerprints stay
+unchanged. Each closed namespace has an indexed immutable receipt, and old
+command IDs remain unique across the run. Current recovery evidence resolves
+only the latest transition and fixed proof slots, without following all epochs.
+
+Qualification uses a four-command controller limit and an eight-command native
+active-turn limit. Native boundary tests start at JavaScript's old maximum,
+rotate repeatedly, reopen after receiver commit, retry old transitions, reject
+conflicting successors/missing durable receipts/wrong namespaces and replay the
+earliest command exactly. Controller tests restart after intent publication and
+lose the receiver reply. Combined native connection rekey/command rotations
+preserve the same live provider PID and turn, with no interrupt or resume.
+
+Initial results: native boundary passed; controller/store/evidence tests passed
+114 checks (`/tmp/paperclip-command-epochs-controller-3.log`); real PostgreSQL
+passed 21 checks (`/tmp/paperclip-command-epochs-postgres-2.log`). Attempt 2 of the
+controller test command used the wrong working directory and ran no tests.
+Authenticated command-resume reconciliation was added afterward; its targeted
+controller and native active tests passed (controller-4 and active-2 logs).
+These results qualify the command lane only. Event, normalized delivery and
+run-log/output namespaces still need independent rotation.
+
+
+Source 35 (7,955 files/five native artifacts) passed repository typecheck and
+build, with all captured hashes unchanged afterward. Runner suite 20 failed
+five timed-out tests: 2,154 passed, 14 skipped. The 525-second thermal sleep and
+148-/495-second maintenance sleeps in the host power log match these long
+elapsed durations. The new command-epoch checks passed in that run. Full Rust
+35 failed one existing direct-provider turn-identity rollover test (five-second
+completion wait); its isolated retry is tracked separately and is not assumed
+to be sleep-related. Log paths use `paperclip-unbounded-{typecheck,build,rust}-35`
+and `paperclip-unbounded-runner-tests-20`. These attempts are not full green
+qualification. The user has been asked to keep the host awake/ventilated for
+live qualification; no power-management settings were overridden.
+
+Before the next candidate, controller close-receipt keys were changed to a
+fixed-length digest of run identity and predecessor namespace. This preserves
+the protocol's full allowed run-ID length instead of exceeding the authority
+key bound for long identities. There are no deployed rotated namespaces from
+these development candidates.
+
+
+Source 36 live browser/Codex campaign `local-2026-09-29T12-39-15-384Z` passed all
+16 checks in 190,491 ms. It killed the controller during active output,
+continued the same provider session, completed two
+turns, and downloaded both original/new output byte-for-byte. The final browser
+screenshot was inspected. All 7,955 source and five artifact hashes remained
+unchanged. The encrypted-controller/store/proof tests passed 115 checks after
+the close-key adjustment, including the maximum 240-character run ID. Controller
+attempt 5 again used the wrong cwd and ran no tests; attempt 6 is the passing
+run. The isolated native rollover retry passed in 82.46 seconds; it does not
+turn full Rust 35 into a pass.
+
+Review found a closed-namespace terminal replay edge: an old suspend/shutdown
+receipt could return a lifecycle stop or fence the new controller connection.
+The receipt must be returned unchanged while current execution continues.
+Native and encrypted-controller regressions for both terminal command types
+are added; same-namespace terminal cleanup/reconciliation remains unchanged.
+
+
+Closed-epoch terminal replay regressions passed: four encrypted controller
+cases and the native test covering both suspend/shutdown. Native storage
+pressure checks passed eight cases. The pressure-control snapshot now carries
+the command epoch, old receipt ordinals cannot raise the current stop cursor,
+and rotation requests remain deferred until the active storage operation
+settles. Rotation also rejects a successor namespace that was previously
+closed, independently of UUID generation. The controller checks that exact
+closed-namespace index before publishing a new intent. These checks are bounded
+lookups, not scans of predecessor history.
+
+
+### 44. Source 37 command epoch qualification
+
+Frozen source 37 (7,955 source files and five native artifact hashes) passed the full release Rust workspace suite and all 21 native transport settlement/rekey cases. Every captured hash was checked unchanged after completion. Targeted controller/store/current-evidence tests passed 117 cases. These results qualify the command lane changes; raw and normalized event ordering, run-log/output cursors and whole-session recovery remain separate work. The real browser active-restart campaign described above ran on source 36, before the final historical terminal and pressure fixes.
+
+
+### 45. Raw event delivery namespaces
+
+Implemented independently negotiated PRP v2 raw event epochs with exact signed
+resume cursors, a persisted sender intent, old-outbox drain and an atomic
+receiver close/head receipt. Recovery repeats a lost reply. ACKs include their
+namespace and old ones cannot discard new output. SQLite and PostgreSQL event
+indexes page each namespace directly. The normalized reader explicitly commits
+each raw boundary after the preceding final frame; its own output counter is
+still a separate remaining lane. Current proof order is bounded and persisted,
+so older epoch slots retain chronology after reopening. Warm run receipts bind
+the old source epoch; native warm activation now retains indexed receipt access.
+
+Validation before capturing source 38:
+- Native old-safe-integer-boundary test passes through four rotations, reopen
+  before and after commit, stale ACKs, conflicting intents, and earliest exact
+  executor/event receipts.
+- Receiver lost-reply/restart test passes three rotations with a lagging
+  normalized consumer, earliest event replay and conflicting transition replay.
+- 123 controller/storage/current-evidence/normalization tests pass.
+- 22 real PostgreSQL coordinator tests pass, including sequence uniqueness and
+  paging for both commands and raw events across namespaces (migration 0295).
+- Two real native process/driver/storage tests pass in 13.58 seconds: sixteen
+  exact output bodies during one held turn with repeated raw/command rotations,
+  encrypted reconnects and unchanged process identity; and three warm run
+  attachments with repeated event namespace changes.
+
+The first live attempt exposed command admission during reconnect at an epoch
+boundary. Persisting the previously authenticated capability now lets admission
+record its exact rotation intent and wait for reconnection. The failed attempt
+is retained. One receiver invocation used the wrong working directory and ran
+no tests; only the corrected package invocation is counted. The prototype
+process-owner backfill fixture needed its synthetic retained evidence order
+updated; the full targeted set then passed. Broader checks and real provider
+browser qualification on this candidate are pending.
+
+
+### 46. Raw event checks and control-lane follow-through
+
+Full native release workspace tests passed on frozen source 38; all 7,959 source
+and five artifact hashes were unchanged afterwards. Repository typecheck first
+caught Rust formatting, then a type narrowing error in the new PostgreSQL test;
+both were corrected rather than bypassing either check. Source 39 additionally
+scopes terminal/warm ACK handling by event namespace and keeps stop, revocation
+and lease expiry effective during the rotation barrier. A normal stop waits for
+the short transition to finish; if that wait cannot finish in ten seconds, owned
+cleanup is requested without falsely acknowledging an uncommitted stop command.
+The focused native boundary test and four actual native transport/driver tests
+pass after those changes. Final recursive typecheck is being repeated after the
+PostgreSQL fixture narrowing fix.
+
+The older frozen full-repository run 6 stalled in its chat integration worker.
+After more than an hour without test progress, an idle event-loop sample and a
+process-tree inspection were saved. The owned invocation was terminated with
+SIGTERM so its wrapper could restore configuration and verify source hashes.
+This is an incomplete/failed broader check, not a green result. Evidence lives
+in `/tmp/paperclip-full-tests-6-hang-termination.json` and the accompanying sample
+and original test log. It is separate from the successful current history tests.
+
+
+### 47. Raw event source 40 qualification
+
+Recursive typecheck passes on source 40. Actual browser → Paperclip → native
+runner → Codex active-restart campaign `local-2026-09-29T13-34-19-408Z` passes
+all 16 checks in 196,062 ms across two turns, preserving the provider session.
+The controller was killed during output;
+both earlier and later output downloads remained exact. Final screenshot was
+inspected. All 7,959 source files and five artifact hashes were unchanged after
+completion. Tiny forced raw/command boundaries were separately exercised by
+native process tests; this browser campaign used the default epoch limits.
+
+### 48. Normalized source epochs
+
+Implemented independent normalized source epochs in the durable reducer outbox,
+exact pending-event ACKs, immutable close/head receipts and bounded proof reads
+on reopen. The first event in a successor carries its predecessor transition;
+the production PostgreSQL sink validates and commits that boundary with the
+event. Ordinals never compare across namespaces. Checkpoint encoding, replay
+paging, driver event IDs and goal projections retain the namespace. Body-local
+chunk offsets permit output spanning the boundary. Trace correlation captures
+actual emitted IDs in each asynchronous operation rather than reconstructing
+IDs from a numeric interval. Steering/interrupt and synthetic item IDs use UUIDs.
+The alternate native coordinator now accepts epoch-bearing normalized input
+with preserved payload hashes and settlement-anchored ordering. Broader
+qualification is still needed.
+
+Development verification: 251 controller/recovery/normalization tests pass;
+three native live cases (raw-only, raw plus normalized rollover every four
+entries, and warm attachments) pass, preserving provider ownership; SQLite
+question recovery passes with both default and tiny normalized epoch limits.
+A real PostgreSQL test passes prefix-gap rejection, multiple epochs, lost ACK,
+old replay, reused/conflicting epoch rejection, and a body spanning the boundary.
+Recursive repository typecheck passes. The broader port/allocator suite passed
+19 existing checks; its new body replay test initially failed because external
+body references needed hydration and removal from the canonical envelope.
+That bug was fixed and the new test passed on rerun. A recovery regression also
+exposed retained sparse ledgers: recovery allocation high-water marks may skip
+holes within the same epoch, while cross-epoch transitions remain exact. All
+143 normalization/runtime regression cases pass after preserving that behavior.
+
+Migration 0296 requires a one-time transactional replay-index rebuild; this is
+explicitly recorded as maintenance cost, not constant-time legacy activation.
+Public event identities and byte-positioned output cursors, plus provider
+generation and goal-revision CAS tokens, are covered in §49. Whole-session
+incremental recovery, admission and containment, retained-session migration admission,
+other providers and final endurance qualification remain unfinished. These
+checks do not enable indexed mode by default or declare the complete contract
+delivered.
+
+### 49. Public history cursors, goal CAS and bounded UI pages (2026-09-29)
+
+The public runner history identity work is implemented in migrations 0298–0299.
+Provider generations switch permanently to opaque identities before their legacy
+numeric namespace is exhausted. Session-goal mutations use opaque equality
+CAS tokens; retained numeric goal revisions remain readable until
+first mutation and are never incremented. Provider source epochs/cursors remain
+separate from this CAS token. Public run-event IDs are opaque text IDs;
+safe legacy integer IDs retain their API number representation and larger IDs
+remain exact decimal strings. `event_epoch` scopes the bounded
+`seq`; indexed epoch heads and semantic-lane link rows preserve page order across
+rollover without globally comparing `seq`. The alternate native coordinator now
+accepts epoch-bearing normalized input while preserving payload hashes and
+settlement-anchored order.
+
+Run-event pages are bounded by serialized bytes as well as row count. When the
+byte budget shortens a page, `historyAfter` on its last row tells clients to
+continue; the API keeps one oversized row intact so the cursor can advance.
+Tail reads identify omitted earlier history. Browser event projections retain a
+bounded row/byte tail with a visible collapsed-history marker. Websocket event
+messages are wake hints only; durable polling supplies event rows. Native
+transcript catch-up is capped at four automatic pages before it jumps to the
+latest tail, and RunnerInspector advances through explicit user-requested pages.
+
+Run-log chunk identity and ordering use the exact decimal byte offset where each
+record begins. UI cursor handling preserves values above JavaScript's safe
+integer boundary, prefers the longer persisted payload on websocket/persisted
+replay, and tracks pruned cursor floors. Transcript windows are bounded by row
+count and roughly 2 MiB with a visible collapse marker; segmented tail reads
+also identify when earlier output was omitted. New chunk identity does not use
+numeric `seq`.
+
+Migration 0299 backfills the public event epoch/link/head index from existing
+rows. The O(history) link backfill and transactional index/constraint changes
+are explicit deployment maintenance work for large databases, not foreground
+continuation work.
+
+Focused proof: public-event PostgreSQL tests pass 29 cases; byte-positioned log
+and rollover tests pass 48; publication tests pass 73; the UI suite passes 51.
+Source 41's Rust workspace passes 649 tests, and the actual browser campaign
+passes all 16 checks. Two runner TypeScript failures found during qualification
+were fixed on the primary checkout. The full-repository source-41 run still has
+failures and is not green; these focused results do not imply full qualification.
+
+The overall history-lifetime contract remains incomplete. Whole-session
+incremental backup, admission and containment, retained-session migration admission,
+remote operation and other provider implementations, and final endurance
+qualification remain outstanding. Existing local indexed-path evidence does
+not enable the format by default or qualify hosted/remote lifetime behavior.
+
+
+### 50. Final-record paging and active-turn race (2026-09-29)
+
+Segmented log heads now retain the exact start of their last record. A tail
+request whose newest record is larger than the requested page begins at that
+record and continues through ordinary bounded pages. Retained heads derive the
+same position by scanning backwards through verified segments, bounded by one
+maximum append; they never scan the lifetime log. The transcript reader follows
+those pages for a terminal run, preserves cancellation and its display budget,
+and rejects a stalled or backwards cursor before merging the page. The focused
+transcript suite passes 23 cases. Fifty local/S3 log-store tests pass, including
+UTF-8 records larger than the page and reopening retained heads:
+`/tmp/paperclip-tail-record-pages-1.log`.
+
+Websocket commit hints are no longer rendered as generic output. Event identity
+uses the opaque row ID, cursor or epoch plus local sequence. Native chat progress
+publication keys also preserve the event namespace. The real PostgreSQL cadence
+and epoch-boundary regressions pass (two selected cases in
+`/tmp/paperclip-chat-progress-epochs-2.log`). The first attempt exceeded its
+30-second database setup hook; a separately prepared owned database allowed the
+same assertions to run without changing production behavior.
+
+Codex active-turn lookup now inspects at most four recent metadata pages. If a
+turn settled between the status read and the page, it refreshes metadata and
+accepts an exact idle status; an inconsistent active status remains an error.
+It no longer accumulates old turns after that race. Three native integration
+cases pass, including a fake provider with an indefinitely continuing completed
+history: `/tmp/paperclip-lightweight-history-focused.log`. The release runner
+and normal artifact staging pass in the isolated development target; no protected
+long-run binary was replaced.
+
+Before that narrow native change, the complete release Rust workspace passed
+653 tests with four ignored, and all 82 runner source/Cargo hashes matched before
+and after (`/tmp/paperclip-native-rust-release.log`). The runner TypeScript
+package passed all 2,178 tests, with 14 skipped
+(`/tmp/paperclip-primary-runner-vitest.log`). These are separate evidence sets;
+they do not claim the old 72-hour processes cover the current candidate.
+
+Source 43's browser attempt did not launch: Docker image preflight hung before
+fixture creation, browser startup or model usage. The failure log is
+`/tmp/paperclip-journal-indexed-live-e2e-public-history-byte-cursors-1.log`.
+All 7,975 source files and five artifacts matched after that attempt. The daemon
+was not restarted because other campaigns rely on it.
+
+The frozen source-41 repository run completed with 13,578 passing and 156 failing
+tests (75 skipped; eight failing files). Its worker failures were traced to
+stale runner JavaScript artifacts: workers bypass Vitest's source alias and the
+old package did not export `IndexedInspectionDecoder`. A coherent package build
+and focused rerun are required; this is not a green repository result.
+
+A fresh, isolated Codex 0.153.4 probe, without model generation, confirmed
+`historyMode: paginated` and metadata-only thread reads. It did not test cold
+resume: a never-started turn had no persisted rollout. The exact-version
+provider loader still has a full-history fallback when no suitable model-context
+checkpoint exists, as described in the architecture contract. Provider pagination
+alone does not qualify that recovery guarantee. Whole-session recovery,
+incremental provider persistence, enforced containment, retained admission and
+final endurance remain open; fresh indexed activation remains opt-in.
+
+Current repository typecheck and build both pass after these changes, using the
+isolated native target: `/tmp/paperclip-history-typecheck.log` and
+`/tmp/paperclip-history-build.log`.
+
+Source 44's actual browser → Paperclip → runner → Codex campaign
+`local-2026-09-29T16-05-32-736Z` passes all 16 checks. Both native turns succeed;
+an active controller restart continues the same run, a second graceful restart
+succeeds, and the same provider session persists
+across turns. Both 29,696-byte outputs download byte-for-byte and both ledger
+entries remain in order. The final screenshot was inspected. The campaign uses
+an isolated embedded PostgreSQL instance; no shared Docker restart was needed.
+All 7,975 source hashes and five artifact hashes still match the captured
+manifest. Evidence: `tests/runner-e2e/results/local-2026-09-29T16-05-32-736Z/`
+and `/tmp/paperclip-journal-indexed-live-e2e-public-history-tail-record-2.log`.
+
+The source-41 qualification checkout rebuilt its generated runner JavaScript
+without changing source. Seven of the eight originally failing files then
+passed, including all native executor, continuation and cleanup regressions.
+The combined rerun still failed 28 chat assertions. Three representative chat
+failures subsequently passed unchanged in isolation: Slack callback ordering,
+Discord fresh-batch selection, and Slack setup detection. Source/config hashes
+were verified after each probe. This points to load/order contention but does
+not establish its complete cause or turn the failed broad run green. A coherent
+source-44 full-repository run is required. These checks do not replace the
+outstanding whole-session recovery and final endurance evidence.
+
+### 51. Provider history selection and controller reattachment (2026-09-29)
+
+Indexed Codex sessions explicitly select `historyMode: paginated` on fresh
+creation and verify the returned contract on both creation and cold resume.
+Unsupported/missing mode fails before turn admission; retained sessions are
+never replaced to hide the mismatch. Legacy Paperclip and other provider paths
+retain their defaults. Four focused native regressions pass, followed by the
+complete release Rust workspace: 658 passed, four ignored, zero failures across
+34 result blocks. The 82 source/Cargo hashes match before and after. Evidence:
+`/tmp/paperclip-provider-history-mode-retry-focused.log` and
+`/tmp/paperclip-provider-history-mode-full-rust.log`. An initial fixture failure
+was its temporary directory's 0755 permissions; private 0700 fixtures corrected
+that setup without weakening storage ownership checks. Normal artifact staging
+passes using the isolated native target.
+
+Controller ownership continues to use exact random lease identities and
+controller identities. Its diagnostic integer generation now saturates safely
+instead of overflowing PostgreSQL's integer type. Exact surviving local runner
+reattachment reads current authority without paging historical unresolved
+process owners. It only authorizes authenticated transport reattachment; dead
+or ambiguous runner recovery retains the owner checks. Six real PostgreSQL
+checks pass, including concurrent claimants at the integer limit, stale lease
+rejection at that same generation, and reattachment with the historical owner
+table exclusively locked. Evidence:
+`/tmp/paperclip-controller-generation-live-owners-1.log`. The initial
+parameterized counter test reused a unique issue identifier; each case now has
+its own identifier. Server typecheck passes.
+
+The installed Codex 0.153.4 limitation is version-specific. Official release
+0.159.0 includes upstream commit
+`e7bbc79f482acf285e50a09a9f898aeb2ce3881c`, which stops cold reconstruction at
+the latest complete compaction checkpoint and persists companion resume state,
+including mid-turn compaction. Its release source matches the inspected bounded
+scanner. An isolated official macOS ARM64 binary was downloaded and verified
+against the release asset digest; the global installation was untouched.
+Credential-free startup and metadata reads report 0.159.0 with paginated
+history. This is a candidate for live qualification, not proof that every cold
+recovery or incremental backup requirement is satisfied. Incomplete checkpoints
+still fall back to full replay. A custom Codex fork is not currently required
+for this particular upstream fix.
+
+The isolated native debug build and targeted transport cases pass: the first
+three-file run passed 22/24 cases; two epoch cases exposed a mechanically broken
+fixture `.split` expression, and the repaired epoch file passes 3/3. Recursive
+typecheck and the sequential repository build pass with the isolated target
+(`/tmp/paperclip-provider-history-typecheck.log`,
+`/tmp/paperclip-provider-history-build.log`). All native test fixtures now honor
+`CARGO_TARGET_DIR`, including absolute and workspace-relative paths.
+
+The coherent source-44 full run exposed stale exact websocket hint assertions.
+The updated safe-progress test checks the committed database row identity plus
+all cursor/commit-hint fields while still forbidding event payload forwarding;
+its focused case and server typecheck pass. Four external-chat crash-boundary
+cases pass after their expected commit hint is updated. Original broad-run
+failures remain recorded; these focused repairs do not relabel that run green.
+
+Product E2E can select an absolute Codex executable with
+`PAPERCLIP_RUNNER_E2E_CODEX_COMMAND`. It records the resolved executable digest
+and whether it came from this override or the pinned default in private
+evidence. Wrapper digests do not establish the wrapped binary version. The
+three helper tests and Product E2E typecheck pass. This permits testing the
+isolated released Codex without changing global configuration.
+
+### 52. Released-provider recovery and packaging checks (2026-09-29)
+
+Source 45 captured 7,981 source files and eight artifacts. Its actual Codex
+0.159.0 campaign `local-2026-09-29T16-52-25-218Z` failed before the requested
+active-tool crash boundary: the standalone binary lacked its required
+`codex-code-mode-host`. The model made no shell/tool executions, reported that
+blocker, and ended the turn. No restart or second continuation was exercised.
+All source/artifact hashes remained unchanged. The failed result, screenshot
+and provider provenance remain retained; reported zero cost is not evidence
+that the model calls were free (76,132 input and 914 output tokens).
+
+The complete official 0.159.0 package contains the native entrypoint, companion
+host, package metadata and resources. The release archive and npm package
+integrities were checked in an isolated installation. Credential-free startup
+checks pass. The installed user/global Codex and repository dependency pins
+were not changed. Future qualification must bind the full package, not only
+the entrypoint hash. Artifact details are in the ignored native target's
+`qualification/codex-0.159.0/companion-host-findings.txt`.
+
+A credential-free cold-resume probe uses valid contiguous rollout ordinals, a
+complete same-turn compaction and the tagged upstream settings fixture. It
+separates metadata indexing, the first resume with no projected history, and
+a third fresh app-server with the projection already materialized. On complete
+checkpoints, that third process resumed 1/64/512 MiB histories in approximately
+33/29/40 ms with 36/37/35 MB resident-memory growth. The incomplete-checkpoint
+64 MiB control remained more expensive (186 ms, 231 MB resident growth).
+These are cached local measurements, not a worst-case latency promise or proof
+of logical read bytes; macOS rusage only measured physical disk reads.
+Malformed historical-line tolerance does not prove that line was skipped.
+Corrected and initial attempts are preserved under `/tmp/codex0159_*`; the
+final structured evidence is
+`/tmp/codex0159_cold_resume_projection_complete_evidence.jsonl`.
+
+The tagged source explains the first-resume cost: model-context reconstruction
+stops at the compaction, but `thread_history_materialization.rs` allocates and
+reads the complete unprojected suffix before applying its SQLite projection.
+A missing/lagging projection therefore remains an unbounded recovery case;
+healthy projected resume and missing-index rebuild must not share a guarantee.
+The pinned older 0.156.0 scanner also still requires a prior turn boundary, so
+its same-active-turn recovery remains different from this 0.159.0 result.
+
+Additional full-suite fixture repairs preserve their original guarantees:
+the compact attention query now explicitly checks that a foreign-company
+insert is rejected (26/26 tests); cleanup uses a transaction-local legacy-row
+fixture and confirms normal writes still reject it (4/4); the historical
+0227/0235 migration test reconstructs the original event table and uses raw SQL
+assertions rather than current-schema columns (1/1). All 15 safe-progress
+conformance cases and their two importing suites (34 cases) pass. Server
+typecheck and diff whitespace checks pass. These are focused repairs to the
+source-44 failures, not a relabeling of that in-progress broad run.
+
+### 53. Complete-package browser evidence and provider boundary (2026-09-29)
+
+Source 46's actual browser → Paperclip → native runner → Codex campaign
+`local-2026-09-29T17-10-39-968Z` passes all 16 checks across two successful
+turns. The active controller restart recovers the in-flight run, the later
+continuation retains the same provider session,
+and both 29,696-byte outputs match their browser and streamed downloads.
+The ledger retains both rounds. The final screenshot was inspected, and the
+evidence manifest reports neither missing files nor credential leaks. All
+7,981 source hashes and 50 artifact hashes, including the complete provider
+package, match the frozen source-46 manifest after the run. Results are under
+`tests/runner-e2e/results/local-2026-09-29T17-10-39-968Z/`; the launcher log is
+`/tmp/paperclip-journal-indexed-live-e2e-provider-01590-complete-package-source46.log`.
+The two turns report 600,353/2,030 and 227,706/1,014 input/output tokens. Reported
+zero cost with unknown billing type is not a claim that they were free.
+
+The coherent source-44 full suite finished with 710 passing, eight failing and
+six skipped files; 13,726 tests passed, eight failed and 71 were skipped. Its
+failures are preserved in `/tmp/paperclip-unbounded-full-tests-44.log`. The
+eight assertions are the fixture failures repaired above. A further suite
+could not collect because its database mock omitted `heartbeatRunEvents`, now
+needed by the imported history service. Adding only those mock columns makes
+all 20 startup-feedback-export cases pass. Source 47 captures these repairs
+for a new coherent qualification; source 44 is not relabeled green.
+
+Local Codex continuation reuses its durable provider home directly; it does not
+copy that home on every turn. Remote settlement still copies and hashes all
+provider persistence directories. Inspection of tagged Codex 0.159.0 protocol
+and implementation confirms that paged history and `thread/fork` do not provide
+an immutable same-session checkpoint: a fork creates a new provider identity.
+There is no provider checkpoint/pinning API to bind an incremental backup.
+Together with the missing/lagged projection rebuild described above, this is
+a provider implementation gap, not something that a Paperclip history cursor
+or an always-successful checkpoint callback can close. The full contract and
+default activation remain unqualified. The subsequent product decision is to
+retain stock Codex and state its limitations, without a maintained provider build.
+
+### 54. Small-receipt maintenance and remaining routing capacity (2026-09-29)
+
+A further native-store regression admits eight batches of 4,096 empty-body
+receipts with a 64 KiB partition target. It checks live shard size immediately
+after each commit, without idle maintenance, then reopens and reads the oldest
+receipt. The prior byte-only maintenance budget fails on batch one with an
+802,816-byte shard: each copy page can stop at 128 rows even when it has not
+used its byte budget. New admission could therefore outrun partition splitting.
+
+Maintenance now reserves work using the larger of the admitted byte and row
+budgets, with fourfold copy headroom. Each operation's work remains bounded by
+its own admitted transaction. The exact new regression passes (9.29 seconds);
+before/after logs are `/tmp/paperclip-tiny-receipt-maintenance-{before,after}.log`.
+The complete native release suite passed: 656 top-level tests, zero failures
+and four ignored across 31 Cargo harnesses, plus three passing nested subprocess
+fixture invocations. This predates the subsequent routing-tree
+change; its log is `/tmp/paperclip-tiny-receipt-maintenance-full-rust.log`.
+
+This fixes leaf-maintenance throughput, not the separate root-routing gap.
+`receipt_routes` still grows inside one SQLite root file; no implemented
+hierarchy subdivides that index. Indexed lookup is logarithmic but does not
+remove that eventual per-file capacity limit. Routing-level subdivision remains
+required by the target contract. Run-log segments use arithmetic paths and a
+bounded head, so they do not have this growing catalog structure.
+
+The earlier frozen real-provider 72-hour campaign
+`local-2026-09-29T05-29-00-733Z` ended as a candidate failure after approximately
+10.4 hours, with 10/73 rounds complete. Its eleventh scheduled execution applied
+the document update but never reached terminal run state before the fixture
+deadline. Separately, browser reads exposed the known historical log-read
+storage-pressure failure. The later log fix does not establish that the missing
+terminal transition is fixed. Neither that failed campaign nor the two still
+running older fake-provider soaks qualifies the current candidate for 72 hours.
+
+
+### 55. Business receipts and bounded routing candidate (2026-09-29)
+
+Business tool actions now commit individual company/issue/run-bound receipt rows
+with their actual effects. The run JSON no longer grows with every tool action.
+The exact original idempotency key is retained and verified after SHA-256 index
+lookup; damaged/colliding records fail closed. Publication and source-attachment
+reuse have indexed references. A malformed reuse result retains its input-tuple
+fence so another idempotency key cannot repeat that known effect. Validated
+server-issued comment references set a comment flag atomically; a partial index
+finds the final response without scanning all progress/preparation comments.
+
+Migrations 0300/0301 preserve every legacy receipt value, including malformed
+values and long keys, then remove only the old map. The comment backfill checks
+company, issue and run. Register/reuse command identities are validated before
+excluding any generated file-preparation comment. Malformed receipts cannot
+exclude an unrelated real response. These one-time migrations require a
+maintenance window. The receipt/file/reuse suites pass 30 tests; the added
+malformed-reuse-fence regression passes all six receipt integration cases.
+Server typechecking and the database migration build passed. Their logs are
+`/tmp/paperclip-native-tool-receipts-guard-{tests,typecheck}.log`,
+`/tmp/paperclip-receipts-damaged-reuse-fence.log` and
+`/tmp/paperclip-native-tool-receipts-db-build-final.log` (the last build predates
+the final damaged-reuse-fence refinement).
+
+The routing candidate replaces flat `receipt_routes`, split-queue and retired
+file tables with bounded B+tree pages and two root heads. The top page remains
+inside the SQLite transaction; it splits into separately verified immutable
+pages after 32 entries. Each child binds its key range, digest and largest
+splittable receipt range. Thus root subdivision, range lookup and split
+selection never enumerate all old receipt files. Updates publish child pages
+before atomically changing the root. Rollback retains the old root. Unreachable
+staged/old index pages remain on disk for now; background reclamation is still
+needed to reduce that storage amplification.
+
+Backup preparation captures one immutable routing root, retains retired source
+files while copying, and stores one resumable copy cursor. It no longer creates
+a historical pin list or copies every route row under the foreground fence.
+Copying replaces references a bounded page at a time; publication verifies that
+all reachable routing pages are local. Native archives, two-store snapshots and
+legacy staging carry the `.sqlite.routing` directory before locator publication.
+Retained flat indexed preview roots require explicit maintenance migration;
+ordinary continuation never performs a hidden full routing conversion.
+
+The first routing implementation created a new root file on every receipt;
+its focused test run was stopped as an obsolete candidate after revealing the
+extra filesystem overhead. The corrected root-in-SQLite candidate passes four
+routing tests (including 1,200 ranges, multi-level subdivision, rollback, corrupt
+and missing pages, and source-independent snapshot roots) and three concurrent
+backup tests. Logs: `/tmp/paperclip-routing-tree-new-tests.log` and
+`/tmp/paperclip-routing-tree-backup-tests.log`. Broader native qualification is
+still running. These component results do not qualify the full recovery design.
+
+History-endurance failures now collect up to 2,000 terminal trace frame headers
+from the existing redacted inspection endpoint, with explicit missing,
+unavailable and truncated states. The artifact omits raw/parsed payloads and
+free-form reasons. The fixture opts into provider tracing only for this flow.
+Its 17 focused tests and E2E TypeScript check pass. No new paid model campaign
+has run for this changed candidate yet.
+
+Source 47 full qualification was interrupted when the business-receipt changes
+superseded it. Its typecheck and runner TypeScript build passed; its partial
+full-suite log is `/tmp/paperclip-unbounded-full-tests-47-interrupted.log`.
+It has no complete test/build result and is not labeled green.
+
+### 56. Bounded backup verification and current qualification (2026-09-29)
+
+The native backup's final verification now advances a durable cursor over one
+routing path per step. It no longer walks the entire routing tree while holding
+the live source operation lock. Concurrent-write/restart tests exercise this
+verification phase. The snapshot fault matrix obtains its interruption count
+from a complete baseline run instead of assuming a fixed number of boundaries.
+Archive admission now accepts canonical opaque revisions and preserves older
+archives that predate the routing directory; native validation still requires
+that directory when the store's format needs it.
+
+The source-49 native suite passed 661 top-level tests, with four ignored, across
+31 Cargo harnesses. Three additional passing summaries came from nested
+subprocess fixtures. All 83 captured Rust/Cargo inputs matched before and after
+the run.
+Source 50 changes only rustfmt in two native files; whitespace-stripped content
+is identical. Its format check, TypeScript build, debug/release native builds
+and atomic staging passed. Archive and retained-migration checks passed eight
+tests. This qualifies those component checks, not the entire lifetime contract.
+
+The source-50 live browser test using the complete official Codex 0.159.0
+package passed all 16 behavioral matchers. It continued the same provider
+session across an active controller restart, completed both runs, preserved the
+ledger, and downloaded matching 29,696-byte outputs. All 7,988 source hashes and
+3,655 artifact hashes matched the frozen baseline. Primary visual inspection
+of the final screenshot confirmed the completed task and readable result; that
+single screenshot does not assess every transition. The campaign remains
+failed: its post-run storage oracle queried the removed flat `receipt_routes`
+table. The failed report is preserved under campaign
+`local-2026-09-29T18-59-05-679Z`; fixing the oracle does not retroactively make
+that report green. Reported usage was 783,319 input and 3,096 output tokens.
+Reported cost was zero with unknown billing type, not evidence of free usage.
+
+The preceding embedded-PostgreSQL campaign failed during bootstrap, before any
+provider calls. Its buffered log did not establish the underlying cause. The
+Docker-backed retry above reached the real browser/provider flow. Subsequently
+the Docker daemon socket became unavailable. Starting the installed Docker app
+restored the test daemon without resetting it or changing host settings.
+
+The broader source-49 test run was interrupted after five assertion failures
+in the chat integration file and a later worker stopped making progress. Those
+five cases passed in isolation; the complete chat file then passed 1,043 tests.
+Their failing durations were below one second, so the standalone run's larger
+timeout does not explain those failures. Their cause is still unresolved. The
+current runner TypeScript suite passed 2,182 tests, skipped 14, and failed one
+5-second encrypted-rekey timeout; all 480 captured runner source/binary hashes
+matched before and after. Neither result is a green whole-repository check.
+
+### 57. Constant-size recovery admission with unretired owners (2026-09-29)
+
+An indexed launch remains unresolved until its process tree has a qualified
+retirement proof. The previous admission path enumerated all such launches and
+could allow replacement after their recorded PIDs disappeared. Neither a dead
+PID nor a dead process group proves that an escaped descendant stopped.
+Admission now asks whether any unresolved owner exists for the exact company,
+issue and normalized session, using one indexed query. Presence prevents
+replacement with `provider_process_tree_retirement_unproven`. Reattachment to
+the exact surviving local runner, or separately verified original remote
+runner, retains its existing authority and does not require retirement.
+
+The classification checks passed 22 tests. Three database integration cases
+passed with isolated Docker PostgreSQL, covering zero, one and 260 unresolved
+owners with vanished recorded PIDs. Earlier attempts with unavailable Docker
+and embedded PostgreSQL skipped the file and do not count as passes. Server
+typecheck passed. This change bounds admission and preserves the ownership
+hold; it does not implement
+containment, retire old owners, or complete automatic source-loss recovery.
+
+### 58. Test oracle repair and environment diagnosis (2026-09-29)
+
+The storage evidence oracle now walks the immutable routing tree read-only,
+using bounded page reads and depth state. It validates digests, child summaries,
+levels, ranges, private non-symlink files, and Rust/SQLite UTF-8 key ordering.
+It accepts the canonical opaque authority revisions and exports receipt totals
+as exact decimal strings in evidence schema v2. Malformed-page diagnostics do
+not echo private page contents. Thirteen focused tests and E2E typecheck pass.
+The standalone SQLite partition test now uses the public native partition
+inspection command; its eleven tests pass.
+
+The sole runner-suite rekey failure was a 5-second test timeout under the full
+parallel workload. Unchanged isolated and whole-file runs passed promptly. A
+15-second budget on that real TCP/SQLite integration test, consistent with
+other integration tests in the file, leaves the global timeout unchanged.
+The subsequent complete runner suite passed 2,183 tests, with 14 skipped;
+480 runner source/binary hashes matched before and after. The original failed
+run remains recorded; CPU/scheduling contention is consistent with the timing,
+not a directly measured root cause.
+
+A direct, disposable embedded-PostgreSQL initialization probe captured the
+previously missing error: `could not create semaphores: No space left on device`
+at `semget(..., 17, 03600)`. Host inspection found 5,136 of 5,152 System V
+semaphore sets and 87,280 of 87,381 semaphore elements in use. This is IPC
+resource pressure, not disk exhaustion. An isolated copy started with
+`max_connections=8`, but that startup probe does not qualify the application
+under a smaller connection budget. Application checks continue using isolated
+Docker PostgreSQL. No host IPC settings or unrelated resources were changed.
+
+### 59. Source-51 live and scale qualification (2026-09-29)
+
+Campaign `local-2026-09-29T19-24-40-799Z` passed all 16 browser matchers and
+the corrected indexed-storage oracle. The actual Codex 0.159.0 provider retained
+the same session across an active controller restart
+and a subsequent run. Both runs completed, the ledger preserved its earlier
+line, and downloadable outputs matched at 29,696 bytes. The primary inspected
+the final screenshot. All 7,988 source and 3,655 selected artifact hashes matched
+before and after. This was a roughly three-minute test, not a days-long result.
+Reported usage was 781,667 input and 3,073 output tokens; cached input is a subset
+of that input count. Zero reported cost with unknown billing is not a free-use
+claim. The earlier failed source-50 campaign remains failed.
+
+The routing-tree release benchmark retained 10,737,418,240 actual receipt bytes
+in 79 partitions and verified the oldest receipt after reopening. Current state
+remained 21 bytes; the root SQLite file was 17,010,688 bytes. Physical receipt
+files occupied 10,909,970,432 bytes and routing pages 3,301,728 bytes. At 10 GiB,
+reopen took 0.681 ms, current-state read p95 was 0.046 ms and 16 MiB batch-commit p95 was
+1,460.611 ms. These are local warm-cache component measurements under concurrent
+test load, not cold provider recovery or a full-product 10 GiB measurement.
+The run took 579.83 seconds. The exact log and provenance are
+`/tmp/paperclip-routing-tree-10gib-release-final.log` and
+`/tmp/paperclip-routing-tree-10gib-release-provenance.json`. The previous 100 GiB
+result used flat routing and does not qualify this tree implementation.
+
+Source-51 recursive typecheck, build and token gates passed. The full test run
+passed all 1,043 chat integration tests at the original test budgets. Docker
+then exited during the tool-gateway file, causing 54 database failures; those
+results remain infrastructure-interrupted. After the installed Docker app was
+restarted, the run continued. The native-session-executor file exposed 100
+failures caused by coordinator mocks omitting the required database default
+`controllerGeneration: 0`. The test fixtures now supply that value; production
+validation was unchanged. The corrected file passed all 480 tests at the
+original 15-second test and 30-second hook budgets; its logged result is
+`/tmp/paperclip-controller-generation-native-session-executor.log`. The complete
+repository run and infrastructure-affected rerun are still pending, so this is
+not a green whole-repository hand-off.
+
+### 60. Routing-page reclamation candidate (2026-09-29)
+
+The native store now reclaims obsolete immutable index pages in bounded steps
+between operations and during idle maintenance. It keeps at most three open
+directory iterators. For each page, its immutable lower key and level permit
+point reachability checks in both current roots. The same partition operation
+lock covers the current-root checks and unlink. No historical mark set, growing
+deletion queue or full-tree scan is loaded on continuation. Restarting a scan
+only repeats work; a deletion decision is always made against fresh roots.
+
+Unfinished writes and backups prevent collection. Exact unpublished temporary
+names are reclaimable under the writer fence. Unknown roots, invalid pages and
+symlinks fail closed. This is index-page reclamation only; exact action receipts
+remain retained. Complete sweep time still depends on the number of files, and
+space reclamation can lag writes or a long-lived backup pin.
+
+Five focused tests passed, covering a 1,200-range multi-level tree, rolled-back
+writes, both live roots, concurrent root changes, source-independent backup
+publication, restart, corrupt pages, owned temporaries and symlinks. The large
+tree test permits at most seven page reads in one cleanup step. The source-52
+release workspace suite then passed 666 top-level tests, with four ignored,
+across 31 Cargo harnesses, plus three nested subprocess fixture invocations.
+Logs are `/tmp/paperclip-source52-routing-gc-focused-final.log` and
+`/tmp/paperclip-source52-full-rust.log`. The scale rerun is still pending. This
+does not close the separate provider checkpoint, enforced process retirement,
+migration admission or whole-session restore gaps described above.
+
+### 61. Cleanup latency and UI qualification follow-up (2026-09-29)
+
+The source-52 release benchmark passed at 10 GiB in 617.98 seconds. Current
+state remained 21 bytes and the root database 17,010,688 bytes across 79
+partitions. Obsolete index cleanup reduced physical routing-page bytes from
+3,301,728 in the previous run to 1,999,498. Reopen took 0.543 ms; current-state read p95 was
+4.888 ms and 16 MiB commit p95 was 1,643.191 ms. These are warm-cache measurements
+under concurrent test load, not controlled comparative performance claims.
+
+Code inspection explains a concrete source of extra read latency: the first
+collector integration performed two cleanup steps after every reply, including
+reads. The next queued read could wait for those filesystem operations. The
+source-53 candidate charges those steps to write maintenance before its reply
+and performs none after reads. Idle collection checks for queued foreground
+requests between pages. Cleanup errors cannot rewrite a committed action's
+outcome. The changed scheduling requires its own native suite and 10 GiB rerun;
+source-52 timings are not used to qualify it.
+
+The first complete UI run passed 6,701 tests and failed 62. A mocked native
+transcript hook omitted the new always-present collapsed-history set, causing
+component crashes. The test fixture now supplies and resets that set. A new
+component assertion verifies that the history-collapse notice appears. The
+protocol surface registry also now classifies `output.body.chunk` as diagnostic
+transport data; normalized messages/tools own the visible content. Both affected
+files passed 161 tests, and token gates passed. The complete UI rerun passed
+6,764 tests across all 640 files with two workers and unchanged test budgets.
+All 2,140 UI/shared source hashes matched before and after; its log is
+`/tmp/paperclip-source52-ui-vitest-final.log`.
+The original failed log is `/tmp/paperclip-source52-ui-vitest.log`; the focused
+result is `/tmp/paperclip-source52-ui-focused-vitest-retry.log`.
+
+### 62. Native cleanup scheduling and broad-check recovery (2026-09-29)
+
+The source-53 release workspace passed 666 top-level Rust tests across 31 Cargo
+harnesses, with four ignored; three nested subprocess fixture invocations also
+passed. Its explicit 10 GiB benchmark then passed in 673.641 seconds. The final
+measurement retained 10,737,418,240 receipt bytes in 79 partitions, verified an
+old exact receipt after reopening, and held current state at 21 bytes. The root
+database occupied 17,010,688 bytes; routing pages occupied 2,301,302 physical
+bytes, with a largest page of 9,295 bytes. Reopen took 2.617 ms, current-state
+read p95 was 0.103 ms and 16 MiB commit p95 was 1,812.353 ms. The measured read
+is the small current-state read, not a benchmark of ancient-receipt latency.
+Concurrent host load and warm caches preclude a controlled speedup claim.
+
+All 5,232 captured runner source hashes matched before and after. The release
+runner was rebuilt and staged in the isolated development target; staging
+applies the macOS signature, so the staged and Cargo-output hashes differ.
+The exact binaries, test totals and logs are recorded in
+`/tmp/paperclip-source53-final-provenance.json`. The source-51 browser campaign
+does not qualify these subsequent native cleanup changes as a product E2E run.
+
+Broad verification also exposed macOS temporary-path aliases in fixtures:
+`/tmp` resolves to `/private/tmp`, so exact-path mocks and assertions may miss
+the canonical path. All 89 sandbox-managed-runtime tests pass using a canonical,
+test-owned temporary root, with source hashes unchanged. CLI coverage comprises
+the 62 initially green files and the worktree file's corrected environment:
+61 tests passed with canonical temporary paths and an isolated source database;
+the remaining two real embedded-PostgreSQL target tests passed after a
+test-owned TCP listener reserved the stale-lock port and exercised normal port
+fallback. The listener was closed afterward. No global lock or unrelated
+process was removed. The original failed suite attempts remain failed records;
+these results are composite coverage, not a successful original full command.
+
+Logs are `/tmp/paperclip-sandbox-managed-runtime-rerun.log`,
+`/tmp/paperclip-source52-cli-vitest.log`,
+`/tmp/paperclip-source52-cli-worktree-focused.log`, and
+`/tmp/paperclip-source52-cli-worktree-portfallback.log`. Remaining serialized
+routes, the interrupted tool-gateway file and a database foreign-key assertion
+are still being checked. No whole-repository green result is claimed.
+
+The two approval-route failures were stale database fixtures that implemented
+the previous direct history query. The fixture now supplies the indexed lane
+ID lookup and bounded row hydration, while executing the real request reader
+and authorization code. Both ordinary-member denial and administrator approval
+assert the canonical request-lane binding; all 74 file tests pass at the original
+budgets. Server typecheck passes after the fixture repair. The final UI-only
+production build also passes with unchanged source hashes. Logs are
+`/tmp/paperclip-source52-agent-live-run-routes.log`,
+`/tmp/paperclip-source53-server-typecheck.log` and
+`/tmp/paperclip-source53-ui-build.log`.
+
+### 63. Latest actual-provider workflow and database version diagnosis (2026-09-29)
+
+Source-54 campaign `local-2026-09-29T20-46-09-880Z` ran the final source-53 native
+implementation through browser → Paperclip → runner → actual Codex 0.159.0.
+Its single active-restart attempt passed all 16 matchers, the indexed-storage
+oracle and cleanup in 181,399 ms. The controller was killed during active output;
+that execution completed with exit zero, and the following run retained the
+same provider session. Both 29,696-byte outputs matched their browser downloads,
+including a later download of the original output. The ledger retained both
+rounds. The primary inspected the final browser screenshot.
+
+All 7,989 source entries and 3,655 selected artifact entries matched before and
+after. The executed Cargo release runner hash was
+`2504efd6e7a36e6c3540eb68c018fae3732651ce24ebd627efea6fa6c1c61961`;
+the complete official Codex executable hash was
+`e89718aa1969bfc4a471277bdc4679a3a3529293de0a309909822dfd67ddb77a`.
+The storage oracle observed current runner/provider states of 38,150/83,586
+bytes and 415/13 receipts. These are short-workflow measurements, not scale or
+elapsed-endurance results. Reported usage was 876,192 input and 3,126 output
+tokens; 775,542 cached input tokens are already included in input. The generic
+report's summed token field also adds cached input, so it must not be used as
+the actual total for this provider. Reported zero cost with unknown billing
+type remains unverified cost.
+
+Evidence is under
+`tests/runner-e2e/results/local-2026-09-29T20-46-09-880Z/history-endurance/runner-codex/local/active-restart/attempt-1/`;
+the launcher/provenance use the
+`provider-01590-complete-package-source54-docker` suffix in `/tmp`. Exact
+provider session identities remain in private evidence, not this design record.
+Subsequent changes are the OpenAPI contract registration and matching test
+inventory described in section 64, plus documentation updates. They are not
+retroactively included in this campaign's source fingerprint.
+
+The interrupted tool-gateway file passed all 71 tests with its original budgets
+and clean teardown in `/tmp/paperclip-source53-tool-gateway.log`. The apparent
+foreign-key regression came from the test fallback's PostgreSQL major version:
+the same RESTRICT deletion produces `23503` on 17 and `23001` on 18, consistent
+with the [upstream error-code change](https://github.com/postgres/postgres/commit/086c84b23).
+The repository pins embedded PostgreSQL 18. Its unmodified foreign-key test
+passes on isolated Docker PostgreSQL 18 in
+`/tmp/paperclip-source51-fk-pg18-unchanged.log`. No schema or assertion was changed.
+The initial Docker 18 probe used the old data-directory layout and skipped after
+startup failure; it is not passing evidence. Corrected probes preserve their
+separate logs and verify source restoration. Serialized route coverage is still
+being completed; the original aggregate test command remains a failed attempt.
+
+### 64. Final contract synchronization and suite follow-ups (2026-09-29)
+
+The remaining 134 serialized suites completed with 2,443 passing tests and two
+failures. The OpenAPI inventory exposed a missing registration for the new
+company-scoped output-body download. The registry now describes the redacted
+text attachment, digest-shaped body identifier, access/errors and bounded frame
+size. Event and log routes also document their exact string cursors and paging
+parameters. The existing run-ID coverage assertion now expects 13 endpoints.
+All 11 OpenAPI tests pass after that update, and direct server TypeScript emit
+passes. Logs are `/tmp/paperclip-source55-openapi-routes-final.log` and
+`/tmp/paperclip-source55-server-compile.log`. The first focused attempt, before
+updating the endpoint count, remains in `/tmp/paperclip-source55-openapi-routes.log`.
+
+The other failure was Chinese issue search under the Docker stand-in's
+`en_US.utf8` locale. The repository's embedded-database helper explicitly requests
+`--encoding=UTF8 --locale=C --lc-messages=C`; the stand-in had ignored these
+flags. The unchanged eight-test file passes on PostgreSQL 18.6 with both database
+collation and ctype confirmed as `C`. The earlier `en_US.utf8` run still fails
+and remains recorded: the unchanged search code's short-term POSIX character
+boundary depends on locale. This work does not repair that separate behavior.
+The passing log is `/tmp/paperclip-source54-multilingual-pg18-c-rerun.log` and
+the failed comparison is `/tmp/paperclip-source54-multilingual-pg18-rerun-v2.log`.
+Both runs restored their owned database resources and preserved source hashes.
+
+The initial general-server run's 16 unhandled errors were also reconciled:
+15 came from the missing controller-generation fixture default and one was an
+injected checkpoint failure in that same affected file. Its corrected 480-test
+rerun has no unhandled errors. The intentionally failing synthetic chat module
+used by the test-runner's own fixture is not an additional aggregate regression.
+The original full command exited unsuccessfully; passing follow-ups establish
+composite coverage without changing that recorded result.
+
+The reconciled ledger is `/tmp/paperclip-unbounded-final-coverage.json`.
+All requested general-server, workspace and serialized-route groups have run;
+no requested catalog entries remain unrun. Its per-group totals retain skips
+and distinguish the frozen candidate from corrected follow-ups. UI coverage is
+6,764 passing tests, CLI composite coverage is 502, and the separate runner
+TypeScript suite has 2,183 passing tests with 14 skipped. The selected Product
+E2E result is one case with 16 matchers, not 16 separate cases or the whole live
+catalog. These completed checks do not close the implementation and elapsed
+endurance gates in the current status at the top of this record.

+After the browser workflow, the launcher performs a read-only storage check

+`snapshots/indexed-storage.json` contains only counts, sizes, and generations;

+[durability qualification status](../../doc/plans/2026-09-28-unbounded-runner-history.md#14-implementation-and-qualification-status-2026-09-28).
+
+The explicit `indexed-history` cell asks the real provider to emit known shell
+output using built-ins, downloads it through the run page, restarts Paperclip,
+answers the task's question, and downloads the same original output again after
+continuation. It compares every byte and the content digest; preview text alone
+cannot pass. Built-ins avoid host Python/Xcode startup diagnostics contaminating
+the exact output fixture. Public screenshots remain confined to the existing
+reviewed task routes; run-page interaction is retained in private browser traces.
+
+The history-endurance grader also records browser run-log HTTP errors. A failed
+old-log read fails the attempt even when the latest task and direct downloads
+succeed; this catches history-page fan-out and read-admission regressions.
+
+The explicit `history-endurance` suite uses the same real browser, production
+APIs, and Codex provider. Start with the three-turn local smoke cell:
+
+```bash
+PAPERCLIP_NATIVE_INDEXED_STATE=1 pnpm test:e2e:runner -- --id history-endurance.runner-codex.local.smoke
+```
+
+The `history-endurance.runner-codex.local.72h` cell performs 73 real turns at
+least one hour apart, restarting its isolated Paperclip controller before every
+sixth continuation, alternating graceful shutdown and a forced controller crash. Every turn prints a distinct diagnostic, updates the same
+task document, and completes. The oracle verifies provider-session continuity,
+the exact ordered document, both new and original browser downloads, and the exact independently retained
+command-output stream. The diagnostic assembles its fixed text and emits it
+in one shell write; this avoids relying on a provider retaining a burst of
+1,024 tiny writes. It requests a one-second shell yield and a three-second
+initial delay so ordinary rounds exercise asynchronous command-output streaming
+rather than completing entirely inside the initial shell response. The
+smoke cell uses the same flow with three turns, one graceful restart, and one forced crash.
+The `history-endurance.runner-codex.local.active-restart` cell forces a controller
+crash after an authenticated event shows the first diagnostic command running.
+The same execution must complete successfully after the crash, and a second
+turn must preserve the provider session and original output. Its fixed 45-second
+shell delay exposes that recovery boundary; it is not a product timeout.
+Each model turn has a ten-minute deadline. These paid cells never automatically
