DottaandPaperclip 492d537340 fix(native): recover controllers across webserver replacement (#18343)
## Thinking Path

> - Paperclip manages AI agents and their work.
> - Native execution runs in a remote Runner while the webserver owns
its controller.
> - Encrypted PRP checkpoints and session snapshots already survive a
webserver restart in Postgres.
> - Ordinary warm and per-turn admission still needs local markers and
supervisor metadata to find that state.
> - Replacing the webserver with an empty native controller directory
can therefore lose a usable retained session.
> - This change adds bounded recovery metadata to the existing snapshot
transaction and reconstructs local projections from the selected durable
source.
> - The benefit is native execution continuity across webserver
replacement, with the existing ownership and agent lifecycle policies.

## Linked Issues or Issue Description

**What existing behavior does this improve?**

Native remote controller recovery and retained-session continuation
during a webserver upgrade.

**Subsystem affected**

server/ — native runtime, checkpoint persistence, recovery scheduling
and internal upgrade reporting. Product E2E qualification also changes.

**Current behavior**

Without both the local PRP marker and supervisor file, normal
continuation can return before discovering the saved Postgres
checkpoint. The snapshot already exists in Postgres, but its local reuse
compatibility envelope cannot be reconstructed.

**Proposed behavior**

Select the existing durable source, validate its identity and ownership,
restore its PRP state and supervisor projection, then use normal
authenticated admission. Missing or inconsistent evidence holds
recovery. It does not authorize fresh provider work.

**Reason and benefit**

A replacement webserver must recover active execution and later continue
its retained session without the old server's native files. This is one
component of deployment continuity. HTTP traffic switching, workspace
storage migration and Railway rollout remain separate.

**Breaking changes**

No new public endpoint, schema migration or database pool. The private
run-profile envelope is additive. Disk-independent rollback also
requires a reader for the staged controller format and compact
checkpoint part; the first production release containing these readers
is the floor. Older file-backed sessions need an owner checkpoint or the
bounded internal importer.

**Additional context**

Related foundations: #17401, #17916, #17254, #14621, #14622. The
implementation contract and open acceptance gates are in [the dated
plan](doc/plans/2026-10-30-native-controller-checkpoints.md).

## What Changed

- Persist a versioned recovery envelope, at most 4 KiB, beside the
redacted session snapshot in its existing transaction. Keep it out of
public run projections.
- Compare frozen admission separately from prepared attachment
instructions during staged recovery, preserving exact
template/identity/authority checks.
- Bound the existing lazy checkpoint pool at three connections after
measured two-slot burst backlog; keep request/renewal capacities and SQL
operation counts unchanged. The tuning is a separate commit.
- Discover and restore the exact selected retained source without local
native markers. Preserve the 32-candidate window, progress barriers and
current authority checks.
- Fence snapshot and result writes. Acquire coordinator, issue and run
locks in order and check expiry after lock waits. Combine snapshot
ownership/read work into one statement.
- Reuse existing recovery deadlines and drain/resume scheduling.
Retained-owner waits preserve the original unstarted run and actual
lease deadline. Stop, ownership and provider-progress fences precede
deferral. Add bounded native evidence reporting, retained-source import
and retention protection.
- Admit a settled warm source with an authenticated idle goal-read
suffix while retaining active-work and mixed-authority holds.
- Permit lifecycle `turn.stop` checkpoints after accepted results under
existing ownership fences. Claim the existing successor coordinator
before retiring the old warm session, and stage shared attachments only
after verified retirement. Preserve omitted isolated-home defaults and
existing fresh skill-selection order during recovery without hiding real
configuration changes.
- Carry the exact durable six-field PRP binding during active recovery
after a healthy warm handoff. Keep the Runner mismatch guard and
preserve opaque attachment IDs.
- Preserve an already verified active or idle warm process during remote
preparation; revalidate its proof/liveness and retain later
authenticated PRP attachment. Ordinary resumed leases retain suspension
checks.
- Drain retained source events under their original authority, reconcile
immutable source accounting and block unknown source tool dispatch
before target work.
- Persist compact staged handoff intent through authenticated adoption
and recover direct/listener command-loss windows without another Runner
or duplicate attachment.
- Rebuild suspended lifecycle receipts for resumed prepared tasks, and
retry missing lifecycle reads after partial PRP materialization without
overwriting contradictory evidence.
- Add normal warm/per-turn diskless continuation coverage, real Postgres
races and SQL-cost checks. Add a reproducible paired load workload.
- Give only the explicit outage fixture a 15-minute provider idle
window, with a red/green catalog regression preserving all production
timing and lifecycle policies.
- Publish the goal-less task-session pointer in the existing
post-acceptance terminal checkpoint transaction, with current ownership,
accepted-result, reset and newer-progress fences. Keep a private bound
receipt so late completion cannot duplicate or resurrect publication.
- Use a retained warm sandbox in the dedicated continuity fixture, and
accept an exact output token followed by an explanation. Keep the strict
identity oracle.
- Extend the explicit Daytona cell to a five-minute active outage and
another replacement after completion. Require retained provider
identity, a new tool receipt and a useful follow-up result. Add an owned
loopback Postgres E2E fixture for hosts that cannot start embedded
Postgres.

## Verification

**Merge recommendation — `fc68584ce6231a02e47ecd743f55b036ccea034f`:
ready for the qualified native-controller component.** Full CI, fresh
review, local application paths, controlled performance qualification
and the strict live Linux/Daytona case pass. Independent resource
cleanup is complete. Broader rollout, browser reconnection and the
unexecuted transport/platform combinations remain integration gates.
Integrated 484 passed full local recursive typecheck/build and ordinary
active→completion→cache-loss→C component qualification. Fresh review
then found a valid attached-wake failure: preparation appends attachment
instructions before the verifier compares execution to the frozen
admission. 9f4 fixes that by separately checking the pre-preparation
admission and exact prepared execution. Both hashes are captured
privately per admission; the full template, identity, configuration and
authority checks remain. Its regression fails before the fix; 36 focused
cases, 42 staged source/target cases and server typecheck pass
afterward. The review thread is resolved. Exact-head full CI passes
([run
41168228822](https://github.com/paperclipai/paperclip/actions/runs/41168228822):
48 successful jobs, one intended skip); the complete `pnpm test:run`
partitions are forced, with the five native suites in the Runner lane.
This is not a claim that an unsharded local command passed. The fresh
exact-head Greptile check succeeds with 5/5 and all six threads
resolved.

The original two-connection database comparison closes **steady PASS and
burst FAIL**. Every relative CPU/WAL/request-p99 gate passes and all
operations/ownership remain correct, but candidate arm 3 drains in
1,015.99 ms and baseline arm 4 in 1,059.67 ms against the unchanged
1,000 ms absolute gate. Those results remain failed. A separate 2→3→4→2
diagnostic reproduces drain times 1,051.57 / 956.79 / 882.02 / 1,065.72
ms: three is the smallest tested passing cap, and the repeated two-cap
failure survives run-order/cache effects.

Separately reviewable `fc68584ce6` changes the existing lazy checkpoint
pool default to three connections. Request capacity stays ten and
liveness two; idle release, shutdown fencing, transaction counts and
pool count are unchanged. Thirteen DB lifecycle/cap tests and DB
typecheck pass. Full recursive typecheck/build pass at exact fc68584,
with the matching server build stamp. The final paired native
feature-cost comparison explicitly uses the **same cap-three policy and
common current DB factory in both variants**; its baseline is
controlled, not the unmodified historical cap-two configuration.
Original gates and workload counts remain unchanged. The one strict
Linux/Daytona case started at 04:40:56 UTC only after both new profiles
passed; it passed on the first attempt with all 49 workflow checks.
Independent cleanup confirms all three owned sandboxes absent, owned
Postgres/controllers/observer gone, VM terminated, root volume absent
and ephemeral SSH key/agent removed.

**Final controlled cap-three qualification: PASS.** Baseline native
implementation `59da15066a` and candidate `fc68584ce6` use the same
current DB factory and checkpoint policy (request/liveness/checkpoint =
10/2/3). Eight 65-second ABBA arms cover 300 controllers and 10,000
historical tasks. All correctness, absolute and 10% relative gates pass;
original cap-two failures remain unchanged.

| Mode | DB CPU µs/op, baseline → candidate | WAL B/op, baseline →
candidate | DB-request p99 ms, baseline → candidate | Maximum drain |
| --- | --- | --- | --- | --- |
| Steady | 542.40 → 554.83 (+2.29%) | 1509.01 → 1558.27 (+3.26%) |
107.11 → 111.90 (+4.48%) | 26.35 ms |
| Burst | 1036.36 → 1063.11 (+2.58%) | 4153.12 → 4317.64 (+3.96%) |
103.736 → 103.841 (+0.10%) | 930.14 ms |

Every matched arm preserves operation/statement/transaction counts,
including 3,900 PRP and 3,900 snapshot transactions. All three actual
pools are included; there are zero lost owners, missed lease deadlines,
dropped operations or errors. Peak Postgres CPU is 18.31%/9.47% of two
cores and memory 614.29/684.42 MiB (steady/burst). The benchmark uses
one Node process simulating 300 controllers; it does not qualify
two-webserver overlap, HTTP latency or hosted capacity. Its observer SQL
contributes to measured database CPU. The original unmodified cap-two
baseline is separately retained as failed; this cap-three comparison is
explicitly controlled.

The exact final-source 8/512/8,192-chunk test also passes: zero recovery
SQL, transactions or changed rows in each text-only interval, zero idle
SQL, seven lifecycle transactions and twelve changed rows per sample.
Existing lease traffic remains separate. The final ordinary managed
application replay passes active recovery, completion, native-cache
removal and C continuation; its UNKNOWN local debug-daemon provenance
and partial instruction-observer limits remain recorded. The live case
uses the attested Linux producer instead.


**Live qualification: PASS, one attempt, no retries.** Campaign
`native-controller-retained-fix-fc68584ce6-ec2-20261031T044055Z` started
04:40:56 UTC on the exact final Linux webserver source; suite definition
hash `12f9bb97823c1537e43f0398e7cddf39890f77bce7b413ca4dfd944f4a30e5d5`.
The existing immutable image and attested Bookworm Runner artifact are
unchanged.

- A was SIGKILLed and its native cache discarded. B started after
300,149 ms, naturally acquired generation 2, authenticated at 316,624 ms
and resumed at 317,682 ms within the original 420,000 ms grace. The same
active run, Runner, provider PID/start fingerprint and one
submitted/started/accepted turn were preserved; one final
result/terminal and workspace finalization completed, with no
retry/recovery action.
- After active and queued completion, B was SIGKILLed and its native
cache discarded again. C received exactly one ordinary task-comment API
follow-up, completed a new tool and produced a useful reply while
preserving native/provider/Runner identities. This closes the earlier
failed post-C gate. A separate C OS-process PID field was not exported;
the physical-PID proof is specifically A→B.
- Four distinct results were accepted and published; all four
finalizations committed at attempt 1, all four accounting-v2 projections
settled, and the task-session pointer advanced to C. The coordinator
independently checked these facts and all 49 canonical checks against
the sanitized receipts.
- Canonical cleanup passed and independent checks confirmed three exact
sandbox 404s plus complete inventory/zero owned remnants, no owned PG or
controller/observer processes, EC2 terminated, root volume absent, and
the ephemeral SSH key/agent removed by 04:54:25 UTC.

Live scope is classic remote Codex warm continuity with non-native
storage dependencies available. Prepared-task completed B→C, full
per-turn application disk loss, browser reconnection, two-server load
and overall Railway/HTTP continuity were not live-qualified here.
Earlier failed campaigns and the original cap-two burst failure remain
failed historical evidence. A report-renderer cache setup failure was
preserved; the normal sanitizer subsequently succeeded with an explicit
cache path and a new output directory, without changing validators.


The repair keeps retained events under their original six-field
authority until persistence and accounting accept them. Unknown semantic
effects stay unresolved. A compact staged target survives source
bootstrap, cached-command delivery and authenticated handoff, including
an uncertain commit response. Direct and same-guest-listener recovery
require the verified original Runner and the exact endpoint. Target
snapshot publication marks readiness in memory, with retirement
coalesced into an existing command write. Headers contain only the
staged descriptor/digest; a prequeue template is written once as a
changed checkpoint part and then recovered from the existing
command/receipt. No second session snapshot transaction, streaming SQL
path, new pool or recurring idle scan is added.

| Current repair gate | Evidence and scope |
| --- | --- |
| Source-tail regression | Real Runner protocol RED reproduced
attachment rejection. Frozen core/transport pass five source-tail cases:
source usage attribution, held persistence/no premature ACK, lost commit
response plus cache loss, unknown semantic hold and accounting rejection
hold. |
| Handoff loss windows | Direct and listener modes pass
queued/prepared/activated/completed boundaries (eight cells), preserving
the actual Runner/provider process. Missing adoption proof and changed
endpoints reject recovery. |
| Compact storage | A 31 KiB attachment grant writes its separate part
once, leaves it unchanged across source snapshots and removes it at
queueing. Headers do not duplicate the grant. |
| Accounting | 21 real-Postgres usage tests and 19 source-binding tests
pass. Recovery hydrates immutable source receipts without resetting
their producer or billing classification; conflicting/incomplete usage
holds. |
| Admission and malformed evidence | Driver 16, staged evidence 42,
restart classifier 27 and source usage 19 focused cases pass. Four
malformed-file regressions pass at d6a7, whose executor is
byte-identical at 484, and server typecheck passes. Full executor file:
990 pass; 16 embedded-Postgres `initdb` setup failures before
assertions, retained separately. |
| Required checks | Exact fc68584 recursive typecheck and build pass
locally, with matching server stamp. Forced full CI succeeds (48 jobs
pass, one intended skip); all PR checks are clean. Maps/token gates pass
for their unchanged source surfaces. Fresh exact-head Greptile is 5/5,
all six threads resolved. |
| Ordinary application path | Exact fc68584 managed component passes
active recovery after natural expiry, completion, native-cache loss and
ordinary C continuation. Production bytes match before/after; temporary
fixtures restored and owned DB/services cleaned. UNKNOWN local
debug-daemon/partial instruction-observer limits remain; the separate
live case uses the attested Linux producer. |
| Producer | Locked Bookworm build from exact 5b7 Rust tree
d03e494217, equal to final fc68584 Rust
source. SHA-256
65b8f8cfdd6099e9ad24f1ca154e8a260777269cc82f6e23c6e6a180c531eaaf;
38,515,328 bytes. Actual Debian 12 execution and live admission pass.
Controller/admission/DB changes do not relabel the producer source. |
| Historical cap-two comparison | Exact 59da baseline vs 5b7 candidate,
300 controllers/10,000 history, ABBA 4×65 s per mode, all three actual
pools and real snapshots. Steady CPU/op 541.36→554.64 µs (+2.45%);
WAL/op 1512.13→1560.99 B (+3.23%); DB-request p99 102.78→105.99 ms
(+3.12%): PASS. Burst CPU/op +4.71%, WAL/op +5.29%, p99 −0.10% pass
relative gates, but absolute drains above fail. Identical operation/SQL
counts, zero lost leases/drops/errors. One Node process simulates 300
controllers; this does not qualify two-webserver overlap or HTTP
capacity. |
| Live acceptance | Strict final-source Linux classic Codex case passes
1/1 on attempt 1, all 49 checks. Active recovery within grace and useful
retained C continuation succeed; four
accepted/published/committed/settled outcomes. Independent provider,
PG/process, VM/root and SSH cleanup complete. Prepared/task and broader
rollout limits are explicit above. |

**Historical qualification snapshot through `9eb9ac6`.** The head at
this snapshot was `9eb9ac6f9e312f3ebe8040f5a7565e88ae8824f3`. Server and
Runner package sources are byte-identical to `283e05ffaa`; the two later
commits change the explicitly scoped qualification and its documentation
only. It includes master through the storage-owner fix
`45a3a92e6dc52d20923b9aa34a22fee2ec5443f9` (#18357). At that snapshot,
CI/review passed but the strict post-C native recovery gate failed; the
PR stayed draft and required another native repair. Prior `39a4343` CI
and review passed, but its full live workflow failed; that grade remains
unchanged. The first repaired `435ccd2` live attempt failed before any
injected outage. It exposed a legitimate terminal snapshot before result
acceptance; no accepted result ID or publication receipt was observed.
Its canonical report remains 0/1 `candidate_failure`, with cleanup
passed and independent provider absence confirmed. `0862062` defers
publication until result acceptance and fixes the fresh review's
coordinator/issue lock-order finding. Both failures have deterministic
real-Postgres regressions. The `0862062` live attempt then proved
accepted-result publication but failed active recovery: a resumed-lease
preparation guard demanded suspension after the exact live Runner was
already verified for adoption. `64c0b746` preserves that verified
active/idle-warm process, revalidates its proof/liveness, and keeps
ordinary suspension checks and later PRP authentication. Its live run
passed preparation but exposed a second active-warm boundary: all
durable binding fields matched except opaque turn/item attachment IDs,
which the server had regenerated. `7a203274` carries the complete
verified six-field binding and keeps the strict Runner mismatch guard.
Its cloud case then passed active adoption, completion, publication and
accounting. The queued continuation exposed accepted-result retirement
writes and an implicit-home fingerprint drift; both are fixed with
deterministic regressions in `39a4343` before this fresh full
qualification.

The prior live case exposed a real publication gap. A goal-less native
turn could persist its accepted result and terminal snapshot before
provider cleanup, while the task-session pointer was still empty. Normal
later admission then selected a fresh session. The fix publishes that
pointer and a private bound receipt in the **existing post-acceptance
terminal checkpoint transaction**, before cleanup. Earlier terminal
observations persist without a handled receipt or continuation pointer.
No result-acceptance or snapshot transaction was added. The late
completion path recognizes the receipt. This also prevents a late
callback from restoring a pointer after a user reset. Goal/control
publication keeps its existing owner.

The dedicated Daytona fixture now uses the existing warm/reusable
environment. Its sandbox, Runner and provider storage must survive. The
former generic per-turn fixture disposed the sandbox after completion
and kept provider-history backup bytes under the discarded directory.
Whole per-turn disk-loss acceptance therefore has a separate
provider-backup storage dependency. It remains distinct from the passing
native per-turn component checks with backup storage available. The
60-second lease, 300-second outage and 420-second grace are unchanged.

| Gate | Current repair evidence |
| --- | --- |
| Assembled regression | Baseline fails with an accepted result and
terminal snapshot but a NULL task pointer while real provider cleanup is
held. The fix passes normal continuation and reset cases, with no
pointer seeding. Exact merged `92b7447` passed 2/2 twice, including
after normal package TypeScript output refresh. Production files are
byte-identical at frozen `435ccd2`. |
| Persistence and concurrency | 19 helper/transaction cases and all 59
existing control-port cases pass on `0862062`. They cover bound result
IDs, reset/newer epochs, Stop, lock waits and expiry, receipt replay,
missing stubs, foreign bindings and atomic 4 KiB rollback. Existing
snapshot transaction count stays one. The new tests reproduce the exact
live missing-result-ID error and the inverse replay/status lock order
against `435ccd2`, then pass after the correction. Replayed results
still reject stale generations. |
| Completion | All 32 completion-boundary tests pass on merged
`92b7447`; the source is unchanged at `435ccd2`. Native result-shaped
session metadata is preserved. |
| Qualification fixture | A valid review report reproduced three
rejected correct replies. Exact token-boundary matching fixes them. 140
focused E2E/catalog cases and Product E2E typecheck pass. Wrong tokens,
marker prefixes/suffixes and wrong authors remain rejected;
retained-identity checks are unchanged. |
| Required checks | Full recursive typecheck and standard build passed
at `435ccd2`. Both exact commands also passed on `0862062`, with its
exact server build stamp; both also pass on `7a203274`, with its exact
server build stamp. Fresh `0862062` Greptile passed 5/5, with zero
unresolved threads. The `64c0b746` normal CI then passed all 49 jobs (48
success, one expected skip) and Greptile passed 5/5 with zero unresolved
findings. The `7a203274` normal CI also passed 48 jobs with one expected
skip, with fresh Greptile 5/5 and zero unresolved findings. Current
`39a4343` recursive typecheck and standard build both pass with
persisted exit codes and its exact build stamp; fresh Greptile is 5/5
with zero unresolved findings. Its normal CI completed successfully: 48
jobs passed and one expected job skipped. The fresh live result remains
separately failed. The `0862062` normal CI had 46 passing jobs, one
expected skip, one worker communication failure and its aggregate
failure; GitHub states the self-hosted runner lost communication. No
failed assertion or specific OOM/spot cause was established, and no
blind retry was used. |
| PostgreSQL supplement | One corrected all-pool pair at the preceding
repair passed 300-controller/10,000-history correctness and absolute
gates. SQL 76,590→75,990; transactions 9,013→8,713; UPDATE rows 11,613
each; 300 correct pointer writes each. PG CPU 31.99→30.46 s, WAL
70.36→67.87 MB, request p99 100.98→103.12 ms. This is one pair, not a
repeated improvement claim or an exact `0862062` CPU measurement. Its
two later changes defer premature publication and reorder existing
locks; they add no transaction, stream/idle writer, pool or timer. The
first collapsed-pool attempt remains invalid and retained. This is not
an exact final-head CPU/WAL measurement; later fixes change ordering,
identity selection and in-memory skill replacement without adding
snapshot transactions, pools, stream writes or idle SQL. |
| Live publication proof (`0862062`) | Baseline run
`06fcc806-f186-4190-9b57-087b61d75533` accepted result
`58f912dc-94d9-4b4d-bd3d-d5f689c83fd3`; the publication receipt names
the same result, the task pointer has parameters and `lastRunId`
matches, and the normalized native identity matches the following active
run. Accounting v2 settled. |
| Active recovery (`0862062`) | **FAIL.** SIGKILL/cache discard at
23:07:28.666 UTC; hold 300,000.859 ms; B ready at 308,896.486 ms;
natural generation-2 ownership at 312,906 ms. At about 319 s,
preparation failed `runner_harness_state_mismatch:
resumed_not_suspended`. No authenticated after-receipt passed within 420
s. Exact original Runner PID 668/start/fingerprint was independently
still alive; provider auto-stop was 15 minutes. No retained C follow-up
qualified. Canonical 0/1 `cleanup_failure`/cleanup-failed report remains
failed; subsequent independent cleanup deleted all three owned resources
with exact 404s and confirmed full intended-account inventory with zero
owned resources. |
| Verified adoption preparation (`64c0b746`) | 91 focused cases pass,
including actual preparation for four active providers and a distinct
prior/current warm proof. Unproved resumed state, dead process and stale
warm owner remain rejected. The earlier options-only fixture missed this
gate. No spawn, backup restore or PRP-authentication bypass was added.
Server typecheck passes. |
| Active warm identity (`64c0b746`) | **FAIL.** B claimed generation 2
at 312,995 ms. Preparation passed, then strict PRP recovery rejected the
generated attachment IDs at about 319 s. The saved and desired Runner,
lease, normalized session and run IDs matched; only
`turn_attachment_…`/`item_attachment_…` differed from generated
`turn-<run>`/`item-<run>`. Canonical 0/1 cleanup-failed report remains
failed; independent cleanup confirmed deletion/404s and zero owned
provider resources. |
| Six-field identity repair (`7a203274`) | Actual server-factory
regression RED4→GREEN38. A real Rust Runner test passes healthy first
run → random-ID warm handoff → held active second run → restored
controller. It verifies a new live authenticated connection, exact
identity, same Runner/provider OS identities, no duplicate launch/turn,
and no redispatch or invented receipt for an uncertain tool. The
synthetic wrong pair still fails the unchanged guard. This protocol case
does not claim business completion. Server and Runner typechecks pass. |
| Active recovery/completion (`7a203274`) | **PASS for the active
component.** Full five-minute SIGKILL/cache-loss hold. B ready at
308,936.651 ms; natural generation 2 observed 312,979 ms; authenticated
at 317,720 ms and resumed processing at 318,527 ms. Same run
`1e1ccb00-0728-4935-97da-57562d81cb42`, Runner
`246f73f7-a689-4177-a9c2-7ce711d63aed`, remote PID 669/start
23:48:27.470, provider lease/session and one submitted turn. Accepted
result `49097529-5310-4ac3-af95-5bf9b91d19f4`, publication, finalization
and accounting v2 all settled. |
| Full workflow (`7a203274`) | **FAIL, preserved.** Queued
late-requirement run `5e61f38d-c7d1-4fc1-bcbf-bce9d46ce4eb` failed
`runner did not durably suspend before checkpoint` before outage 2.
Canonical 0/1 candidate failure, cleanup passed, evidence valid. C
retention was not exercised. Independent provider absence,
controllers/PG cleanup, EC2 termination and root-volume absence all
confirmed; closed receipt SHA-256
`676a3b15eb9937b6bf995c36fb8666c88964d509e5ceb9109fb02da0aa2bc909`. |
| Retirement and stable configuration (`39a4343`) | Real Runner +
Postgres RED reproduced the exact suspension failure and nine owner
rejections. `turn.stop` is now lifecycle checkpoint maintenance under
unchanged owner/result/generation fences. GREEN25/25 proves actual
persisted suspension, exact identity and completed stop/drain/suspend;
unaccepted, foreign, stale and new-work negatives remain rejected. Two
default-home fingerprint REDs become GREEN9/9; explicit mode changes
still invalidate. No global matching exemption or historical fingerprint
rewrite. |
| Fresh full Daytona warm cell (`39a4343`) | **FAIL, preserved.**
Launched 00:15:29 UTC with automatic retries disabled. Active adoption
passed: actual offline hold 300,000.848 ms; B ready 309,922.155 ms;
natural generation 2 at 311,821 ms; authenticated 317,989 ms; resumed
330,440 ms. Same run `3e126819-e786-4b3b-b923-c975cf4f5b79`, Runner
`4079138a-8d7c-44a4-8558-07a5411d1f55`, PID 668/start and
provider/session identities. Accepted result
`08e504af-4dec-48a8-bf05-bf0a32280559` and publication passed. Queued
run `31d168c9-7ab9-4700-abb6-fafb90912237` failed the same strict
suspension error before outage 2. Its row selected a new native
identity, but no new third provider process or invocation was observed.
Recovery-time configuration still reset only `adapterConfig`; native
provider, context and workspace subtrees were unchanged. Canonical 0/1
candidate failure, evidence valid, normal cleanup passed; all campaign
provider/PG/process resources independently absent. Closed campaign

EC2/SSH remain temporarily held for the concrete follow-up repair.
Original 60/300/420-second limits and strict queued/second-replacement
checks remain unchanged. Direct-process path; no new live prepared-task
claim. |
| Native retirement authority (`283e05ffaa`) | Exact `39a4343` facade
regression RED3→GREEN9. The successor now uses its existing production
coordinator claim and prompt renewal before strict retirement. A real
Runner/Postgres case starts in the actual native-observed/unclaimed
phase, claims through production code, then closes and durably suspends
the predecessor in 1.657 s. All 25 real-Postgres cases pass;
unclaimed/foreign writers remain rejected. Shared attachment staging
stays after retirement; Stop and denied claims neither close nor stage.
No new claim or SQL path was added. |
| Configuration continuity (`283e05ffaa`) | Real shared/project-primary
environment selection → configuration with four skill versions
reproduces `reset: true`, changed category exactly `adapterConfig`,
after a Postgres JSONB read. Pinned restoration had reordered the
generated preference while actual runtime skills stayed identical.
Replacing existing pinned rows in place preserves the original fresh
name/key order and fingerprint. The assembled regression passes, as do
three existing pinned-version/rename/alias cases and server typecheck.
Genuine model/skill-selection changes still invalidate. No
fingerprint-format change or broad compatibility exemption. |

PASS: 48 jobs plus one expected skip. Fresh review 5/5, zero unresolved
threads. Live baseline, recovered run and queued continuation all
succeeded, each accepted/published/committed once with accounting v2
settled. Their native/provider identities and configuration fingerprint
match; both recovery and continuation report no reset, no changed
categories and task-session reuse. Active outage/authentication remains
within original timing. |
| Browser-dependent continuation (`283e05ffaa`, definition 6) | **Whole
cell FAIL, preserved.** After B was killed at 00:46:38.928 and its cache
discarded, C became ready in 9,151.410 ms. `openParent()` then hit a
30-second `page.goto`/DOMContentLoaded timeout before posting the final
request. No fourth native run or C continuation was exercised. Cause of
navigation timeout is unknown. C task had no execution lock, queued
comments, handoff or recovery blocker; all three prior runs were
committed/accounted. Normal cleanup passed; independent provider
absence, controller/PG cleanup, EC2 termination and exact root-volume
absence confirmed. Sanitized report bundle SHA-256
`2a3b841d62efb2ae30ef14f96a431ac4fa7fe3a782f1144831512f78edc65022`. |
| Native API continuation qualification (`9eb9ac6f9e`, definition 7) |
**FAIL, preserved.** The real post-C API request dispatched run
`c71fbb18-f979-4fe4-93ce-9c4be46dbf21`, which failed
`native_session_interrupted` / `native_session_recovery_failed` at
01:10:00.640 UTC. It selected the same normalized native identity,
Runner and checkpoint-provider identity as the three succeeded turns. No
C result was accepted; pending accounting remains explicit. Active
recovery passed: actual offline hold 300,001.098 ms, B ready 308,335.019
ms, natural generation 2 observed 311,818 ms, authenticated 315,540 ms,

and cleanup passed are unchanged; that classifier does not establish the
root cause. All owned provider/PG/process resources, EC2, root volume

| Current required checks (`9eb9ac6f9e`) | Recursive typecheck, standard
build and exact build stamp PASS. [Normal
CI](https://github.com/paperclipai/paperclip/actions/runs/41152908417)
PASS: 48 jobs plus one expected skip. Fresh Greptile 5/5, latest edited
summary checked, zero unresolved threads. Exact8/512/8,192 stream probes
again report zero recovery SQL/transactions/rows and settled-idle SQL;
seven control transactions/twelve changed rows each, with 36 separate
legitimate renewals in the longest case. CI success does not supersede
the failed live C gate. |

The completion supplement observed secondary request/liveness/checkpoint
transaction p99 increases of 23.0%/45.7%/15.6% in its single pair.
Renewal p99 stayed below 0.865 s, with 900 successful renewals per arm
and no lost leases. The named pool caps stayed 10+2+2. An aggregate
activity sample peaked at 15 non-observer entries without backend-type
classification, so no claim is made that all were client connections. No
sampled lock episodes does not establish zero lock waits.

Twelve pure reader/selector cases also pass with the new adjacent
receipt. This is not another executed process rollback. Development
reader `5cf7aead` can parse the recovery state, but its old run-detail
redactor can expose receipt IDs/outcome to an authorized run reader. The
first production release containing recovery readers, complete
attachment-identity handling and both private-field redactions is the
rollback floor. The implicit-home fix prevents new recovery-time
fingerprint drift; it does not rewrite previously stored fingerprints
from failed candidates. The development probe is not a published
supported rollback target.

Latest actual `0862062` Runner tests independently passed 8/512/8,192
text chunks with zero recovery SQL, transactions and changed rows, plus
zero settled-idle SQL. All three observed seven setup/control
transactions and twelve changed rows. The 8,192-chunk case separately
recorded 31 legitimate lease-renewal statements, with no lost lease.
These are component SQL observations, not a production CPU/WAL claim.
The new adoption and identity branches affect recovery preparation only.
The `64c0b746`, `7a203274` and exact `39a4343` CI independently passed
all three stream sizes with the same zero-SQL/idle result; each latest
8,192-chunk case recorded 36 separate renewal statements. Exact
`39a4343` Runner 2/2 passed 133 files / 2,317 tests plus two skips; its
separate native group passed 150 tests plus eight skips.

The first API fixture revision omitted the mandatory final screenshot;
this was caught before paid launch and allocated no provider/model work.
The correction captures the actual retained Chromium page with an
explicit unqualified-browser label, without changing the standard report
validator.

Automatic approval review rejected exporting raw private API/workflow
snapshots because of sensitive payloads and insufficient
destination-specific authorization. Sanitized reports and
bound/hash-only receipts are retained; raw snapshots were not copied
through another channel. This does not change the failed grade.

Repair characterization also preserves its failed attempts. An
unconditional staging relocation broke three existing same-scope
scripted cases; the final implementation defers staging only for an
actual superseded warm scope, and all nine order/race cases pass. One
baseline transform overlapped an edit and is explicitly invalid; the
actual immutable `39a4343` loader then produced the three genuine REDs.
The independent task-directory hypothesis produced a RED but was
excluded by the live shared-workspace evidence; no directory policy
change was landed. A shared-workspace fixture authorization omission was
corrected separately from the four-skill semantic RED.

Setup failures are retained separately from semantic outcomes. These
include an old host port after the owned Postgres fixture restarted and
a sandbox-denied TSX IPC pipe. The supported external-Postgres run
passed, and the final exact recursive typecheck passes with normal
process permissions. Seven stale declaration errors after the master
merge cleared after compiling the actual merged SDK/Runner TypeScript
sources. No declarations were edited by hand.

<details>
<summary>Earlier qualification measurements and failed attempts
(historical, before this repair)</summary>

**Historical blocked gate (before the repair below).** Final native
implementation is `abed921e12d543b62f57a56435419c0dafb0bc33`; current
branch head is `af9e2d157dcc349e55374ad186c9be2d6cb96bf9`. The two later
commits change only qualification fixtures, their matcher and
documentation; `server/` and `packages/` are unchanged. It includes
master through `fd008979f5794fda3d5f54151d36acd31d0de140`.

The live Daytona measurement proves five-minute active recovery,
once-only completion and accounting, but **fails retained-session
identity after the second replacement**. The saved checkpoint and
recovery metadata exist. The task-session pointer remains empty, and
ordinary admission creates new native/provider sessions. The exact
skipped publication boundary remains unproven. A useful saved-file
result alone does not satisfy retained-session continuation. This
application-path gap blocks merge independently of CI.

A separate new-master CI failure is owned by the storage workstream (fix
in #18357). No storage guard, session-identity oracle, lease/grace limit
or provider result was relaxed.

| Gate | Observed result and exact scope |
| --- | --- |
| Distinct source recovery and compatible rollback | PASS at A
`5cf7aead09a2d9c7e2f2929d761f535ef3c1d798` → B
`5ea45f8d17e33c9a62bd79982dcf0375b07733d0` → fresh B → A. Four
controller processes, natural 60-second lease expiry, absent native
projections before replacements, three succeeded/committed unique
results, one provider thread, unchanged Runner identity, and strict idle
cleanup. 177.782 seconds. |
| Immutable installed native component | PASS at installed A
`5cf7aead09a2d9c7e2f2929d761f535ef3c1d798` → installed B
`eaef0d56552c087aaa4fa68a8655282ffbd12667` → fresh B → A. Each
controller imports its contained compiled server and DB. Three unique
committed results, stable Runner/thread, no extra provider restart on
same-contract rollback, strict cleanup. 106.672 seconds. This is
compiled component proof, separate from full CLI-native application
acceptance. |
| Normal public CLI startup | PASS for B
`eaef0d56552c087aaa4fa68a8655282ffbd12667`, Node 24.22.1, darwin-arm64:
fresh external DB, 415 migrations, health ready, root HTML 200, company
POST 201 plus GET readback. The installed tree remained unchanged after
execution. |
| Five-minute component outage | Actual controller absence 300,168 ms.
Natural generation-2 claim at 407.196 seconds after crash, same provider
attempt and Runner, original run succeeded/committed. The larger
540-second case timed out before its retained follow-ups, so it is an
active-adoption pass, not a complete four-controller pass. The complete
short source/installed cases above independently cover follow-up and
rollback. |
| Drain/resume review regression | Fixed in
`226f03e736d1ee99fea1762ab32ea3a8a9241c20`. Five facade-level cases
pass: overdue normal/restart waits, future timer cancellation, another
facade resuming the original owner, and transient retry. Against exact
prior scheduler `5ea45f8d17e33c9a62bd79982dcf0375b07733d0`, four fail
and one passes. The later head changes documentation only. |
| Final corrected-fixture Daytona | **PARTIAL: active recovery PASS;
retained identity FAIL**, exact live source `0b6afc499f`. A was
SIGKILLed and native cache discarded; actual offline hold 300,000.375
ms. B was ready at 308,326.961 ms, naturally claimed generation 2 at
312,059 ms, authenticated at 315,996 ms and resumed processing at
316,519 ms, within the original 420-second boundary. The same run,
Runner PID/start, session, lease and event prefix survived; one turn
submitted. Original execution succeeded and settled accounting. After
completion, B was killed and its native cache discarded; C was ready in
9,077.779 ms. C executed the saved project and returned correct
`queue_r`, with all four runs succeeded/accounted. However, native and
true provider-session identities changed: the unchanged retained oracle
fails. No whole-workflow pass is claimed. |
| Prior matched-producer Daytona | FAILED at exact `abed921e12`. The
matching current-source Runner passed normal admission, completed the
first task and settled its accounting. During the active revision, A was
SIGKILLed and its native cache discarded. Actual offline hold was
300,000.727 ms; B was ready at 308,304 ms and naturally claimed
generation 2 at 309,651 ms. At about 318 seconds, the remote process
check reported `process_not_running` for the original admitted Runner.
No authenticated after-receipt or retained follow-up passed. The current
failure is preserved; no automatic retry, lease/grace relaxation, debt
edit or provider replay is used. Bounded forensic read found preserved
exact-bound state with no recoverable failure, a transport-reset
diagnostic and no terminal delivery; this supports external process loss
without proving the exact cause. The sandbox had a five-minute auto-stop
policy, conflicting with the required surviving-sandbox assumption.
Owned cleanup precedes the separate corrected-fixture case. |

**Live retained-session boundary.** Prior completed run `3806…` and C
follow-up `8adf1df3-6744-40bf-b35d-100451f29d9f` both have database
session snapshots and `nativeControllerRecovery`. Their tool
fingerprint, provider configuration, workspace descriptor,
runtime-context digest, driver and work mode match. There is no recorded
force-fresh/workspace-selection change, and this is an ordinary task
rather than a conversation-generation reset. The same issue/agent
task-session row has `session_params_json: null` and `last_run_id: null`
from baseline time. Both native normalized UUID and actual provider
session/thread hashes differ after C. Full application admission
therefore did not select the retained source. No fallback to file
execution or relaxed identity comparison is accepted as proof of
continuity.

**Independent cleanup completed.** Full current-account provider
inventory confirms no resources owned by either final fixture, with
exact-ID absence checks. Owned controllers and campaign Postgres are
stopped/removed. EC2 `i-01551c09af098dde5` is terminated, its
delete-on-termination root volume returned `InvalidVolume.NotFound` at
22:14:08 UTC, and the temporary SSH key/agent were removed. The
canonical failed report and immutable oracle input are retained. Closed
qualification receipt SHA-256:
`b4b5fefce287ebfdbf2cc2238efaad62d8ad485aed0e9c0628ae95dbc18a8575`.

**Original measurement and grader repair remain separate.** The C reply
contains the requested marker followed by a newline and the correct
output. The old workflow waited for one literal space, so its normal
receipt collection stalled; that original attempt was closed and its
canonical `cleanup_failure`/interrupted result is preserved. Commit
`af9e2d157d` repairs only this reply predicate, with 144 focused cases,
E2E typecheck, discovery and diff checks passing. Ordinary string
matching stays literal. The corrected predicate accepts the saved reply,
but the unchanged retained-identity oracle still fails. Pure
active-recovery grading of the captured measurement passes 7/7; this is
not a rewritten passing campaign.

The sandbox idle-window conflict was corrected only for this explicit
fixture (15 minutes). Actual baseline and later sandbox metadata confirm
that policy; the original active box was disposed before a post-gate
policy read, so its 15-minute setting is established by the normal
create/environment configuration rather than an after-read of that box.
Production native lifecycle and the 60/300/420-second constants remain
unchanged.

The development compatibility reader A is a genuine backport commit
based on `59ff89a18fe1312b5f0bb908439bbdb1237b0252`, with the required
idle-goal reader fixes. It is not a previously published release. Its
older executor differs from B. The rollback floor must include this
reader capability. The source component cases admitted the Linux ARM64
Runner packaged at `59ff89a18fe1312b5f0bb908439bbdb1237b0252`; the
installed component case admitted the `5cf7aead` package. Their Runner
bytes are identical: SHA-256
`b1f04caa1ce04e720dec7eb62ede170eb3621948c0849b8f305ea5c5116bced8`. Each
admitted artifact remained unchanged throughout its case.

[Final public package
build](https://github.com/paperclipai/paperclip/actions/runs/41121460635)
and [reader-floor
build](https://github.com/paperclipai/paperclip/actions/runs/41122170506)
both passed all four daemon builds, package assembly and both Darwin
clean consumers. Both Linux ARM consumers failed before provider work
with the same existing local Codex permission-profile error: bubblewrap
attempts `activity.fifo/.git` and reports “Not a directory.” This
matched baseline failure remains open; it is not a native remote
continuity pass. Full post-run tree and build-stamp revalidation also
passed after the compiled native case. The installed component trees are
A `c29114c1bf71c5af00f761aeb9e3d84ed3d3075b9f5600dee3ef2543eb2b6ec5` and
B `eda575505373a3bdc630fa4919862b359791fe3a7ef637961a25b73b38efe4b0`.

**Controlled PostgreSQL qualification passed.**
Baseline/candidate/candidate/baseline workloads used 300 controllers,
10,000 historical tasks, real snapshot/encrypted PRP writes and
unchanged pools. PostgreSQL and client were each limited to two CPUs and
1536 MiB on an isolated eight-vCPU Linux host.

| Workload | PG CPU per operation | WAL per operation | Database request
p99 |
| --- | ---: | ---: | ---: |
| Steady | +1.18% | +1.81% | +1.91% |
| Aligned burst | +3.40% | +2.56% | +3.81% |
| Two logical servers | +3.11% | +2.56% | +9.68% |

All arms passed absolute/correctness gates with unchanged control
transaction counts, no dropped operations and no owner loss. Overlap p99
has little margin below the relative threshold. It uses two clients in
one Node process, not two HTTP servers. [Closed measurements and
limitations](doc/plans/2026-10-30-native-controller-qualification-evidence.json)
and exact-source reproduction patches are retained. [Earlier
contended-host
failures](doc/plans/2026-10-30-native-controller-load-evidence.json)
remain unchanged. The production DB-claim probe claimed 300 owners in
2.84 seconds and restored/committed controls and snapshots in 8.74
seconds, with zero owner loss or settled-idle SQL; its provider
references were synthetic. The measured checkpoint/snapshot/renewal
paths retain the same persistence behavior after integration; later
accounting and business writes have separate owners.

Actual Runner stream tests at `da8c7f6e1837ddd896dfe83a7524812fee813487`
passed 8/512/8,192 chunks: zero recovery SQL, transactions and changed
rows during text intervals; zero settled-idle SQL. Each retained seven
control transactions and twelve changed records. Existing renewal SQL
was measured separately. The guard/scheduler fixes add no stream path,
pool or recurring idle scan.

The live fixture used current-source producer SHA-256
`f0000c90cb83880191479da639201e659aa6ce0fc7d67c859faa172ec977849e`, a
normal locked exact-head build with pinned Rust 1.97.1 in Bookworm.
Actual network-isolated, read-only ABI execution passed (GLIBC
requirement 2.34 against runtime 2.36). The immutable base image
remained
`ghcr.io/paperclipai/paperclip-daytona-runner@sha256:36069788f53c51f228764fa36180575443dfb5d1f84a342d7c0daceb28dc61cc`,
source `a0ef3ce7`. This was an unpublished development producer,
explicitly distinct from the base image and admitted before the fresh
fixture began. The earlier host build failed ABI preflight before
admission. The preceding old-producer fixture completed its initial task
but lacked the usage-basis marker required by current master; it
remained pending/unpriced and correctly paused. It was independently
cleaned without debt or budget changes. Two preceding local Linux setup
attempts OOM-killed before provider allocation, and their cleanup
passed. These attempts remain separate from the final recovery failure.

**Failures retained and resolved separately.** The earlier `98f05fc`
probe rejected a valid settled PRP v2 goal suffix; `eaef0d5` fixed that
reader and the fresh follow-up passed. Later component cleanup failures
were traced by a scoped exception observer to the fixture adapter
rejecting directory downloads. A bounded owned-directory transfer with
exact-byte/mode preflight corrected the fixture; source and installed
strict-cleanup cases then passed. No production guard was relaxed. The
initial local integrated control-port run hit its 30-second embedded
Postgres startup hook before executing 59 cases; 18 other focused cases
passed. A bounded rerun used a fresh owned external Postgres fixture,
applied normal migrations before Vitest, and passed all 59 cases with
the original timeouts unchanged. Its container and data were removed;
the failed attempt remains retained.

The additional opt-in full Product E2E Vitest run is not green: 5,313
passed, seven failed and three skipped. An actual `abed921e12` archive
with the same dependencies, Node and IPC permissions reproduces all
seven failures with the same reasons. Five are unchanged
workflow-policy/profile-pin assertions, including Pi profile version 37
versus the test pin 35. Two database suites failed during embedded
Postgres startup before their assertions; semaphore exhaustion is
confirmed in the observer log. The observer passes its supported
external-Postgres rerun with original timeouts and source unchanged. The
controller-database client-kill/postmaster assertions remain unexecuted
after `initdb` bootstrap failure; no external override is supported. The
unit launcher stopped before its Node-test phase, which was then run
independently and passed 181/181. The original failed full run is
preserved. These results remain distinct from the passing focused checks
and normal repository CI. The first local Product E2E typecheck also
encountered stale compiled Runner declarations; a genuine package-local
TypeScript compile refreshed them and the unchanged check passed,
without a dependency install or producer rebuild.

Earlier [Daytona campaign
41108162900](https://github.com/paperclipai/paperclip/actions/runs/41108162900)
failed at sandbox creation before any agent, with the underlying
provider error unavailable. Its [sanitized
report](https://d1p6rlowie26tp.cloudfront.net/runner-e2e/campaigns/gha-41108162900-2/index.html)
remains a `cleanup_failure`. Both old creation names are absent in the
current authenticated account, but the old CI account identity was not
retained, so account equivalence is unproven. The subsequent exact
`eaef0d5` source Product E2E attempt passed image/agent setup and the
initial project, then held the controller offline for 300,003.7 ms. Its
Mac supervisor failed owned-process inspection before B readiness; no
adoption passed. Full current-company lease/label checks, provider
deletion, exact-ID 404s and complete inventory confirmed cleanup of that
attempt. Its local server and owned Postgres stopped. The prior AWS
campaigns and database qualification VM were terminated with root
volumes removed.

The old admitted test Runner lacks the newer usage-basis marker
introduced on master. The integrated component B turns retained
unpriced, incomplete accounting obligations with `costAccountingPending:
true` and no settled charge. The compatibility-reader A turn used its
legacy receipt interpretation but likewise retained pending accounting
and no settlement timestamp. This proves obligation preservation, not a
whole-run accounting migration. Runner/receiver release ordering remains
governed by the usage owner's contract.

At native implementation `abed921e12d543b62f57a56435419c0dafb0bc33`,
Greptile was 5/5 with zero unresolved threads and CI completed with 54
successful checks and five expected skips. At `0b6afc499f`, Greptile
again passed 5/5 with zero unresolved threads, but CI ended with 51
successful checks, five skips and three failures. Server 9/12 fails a
deterministic managed-skills maintenance assertion newly inherited from
master `198218bf` in merge `c80e00ad`; that test is absent from the PR
head, and the storage owner has the explicit-StorageService fix in
#18357. Runner 2/2 passed 2,283 unit cases but its runner received a
shutdown signal during the long stream probe; its cancelled step and
aggregate failure are preserved. No blind retry was used. Current
`af9e2d157d` checks are pending; the matcher-only change passes 144
focused cases and Product E2E typecheck. Earlier scheduling-sensitive CI
failures and the interrupted unsharded local test run remain recorded in
the dated plan. CI runs the repository's normal test partitions. Final
verification does not claim Railway rollout, uninterrupted HTTP service
or whole-webserver filesystem loss.

## Risks

- The task-pointer repair passes its assembled regression. The first
live repair exposed pre-acceptance ordering and the fresh review exposed
a replay lock-order issue; both are fixed and pass real Postgres tests
at `0862062`. The following live attempt exposed the
verified-running-versus-suspended preparation gate. Its narrow fix
passes 91 focused cases at `64c0b746`. The next live case exposed
synthetic attachment IDs; `7a203274` fixes that field selection and
passes real Runner authentication. The subsequent queued continuation
exposed strict retirement maintenance and a false default-home change;
`39a4343` fixes both with real Runner/Postgres and fingerprint
regressions. The `39a4343` live continuation failed again despite green
CI. `283e05ffaa` repairs the actual native-observed admission ordering
and reproduces/fixes the JSONB skill-order fingerprint drift. Both pass
targeted real-Postgres regressions and the live active plus queued
paths. The definition 6 post-C browser navigation timed out before
admission. Explicit definition 7 now verifies native continuation
through the ordinary comment API; its strict post-C native gate failed
after a real dispatch and remains historical failed evidence. The final
fc68584 repair now passes its fresh strict 49-check Linux/Daytona
campaign; the prior failed grades remain unchanged. Browser reconnection
is handed to its own workstream with the original failed evidence. No
prior failed campaign is reclassified as passing.
- Incorrect checkpoint/source binding or stale ownership could duplicate
external work. Missing evidence remains a hold; existing receipt and
finalization owners keep uncertain effects unresolved.
- Recovery must retain maintenance writes after accepted results without
allowing a stale business turn to write. Real lock-wait and generation
tests cover that boundary.
- The current two-connection paired burst profile fails its absolute
drain gate in both baseline and candidate, despite passing relative load
gates and all correctness checks. A causal capacity diagnostic selected
three slots; the final controlled cap-three profiles pass unchanged
thresholds. Full application replacement and two-server overlap capacity
remain separate. There is no new streaming writer, pool or recurring
idle scan.
- The remote sandbox and Runner must survive the recovery window.
Provider auto-stop is a separate lifetime bound from reconnect grace;
the explicit qualification fixture uses a longer idle window.
- Workspace and provider backup availability remain external
dependencies. This PR does not certify whole-webserver filesystem loss,
uninterrupted HTTP service or a Railway rollout.

## Model Used

Implementation and initial verification used OpenAI GPT-6 through Codex;
the initial hosted snapshot was not exposed. The follow-up qualification
used three OpenAI `gpt-6.1-sol` workers coordinated through Codex, with
repository tools, code execution, CI and scoped test infrastructure.
Context-window size is not exposed.

DottaandPaperclip 9f524ec1a7 fix: persist native Runner usage before transport acknowledgement (#18354)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Agent execution must preserve usage so Paperclip can price work and
enforce budgets.
> - Remote Runner execution can outlive its web receiver.
> - The receiver previously acknowledged Runner events before its later
usage recorder saved the accounting receipt.
> - This pull request saves required native usage receipts before that
transport acknowledgement.
> - A replacement receiver can accept the same retained report and
create one ledger charge.

## Linked Issues or Issue Description

**What happened?**

Native remote Runner usage could leave its durable outbox before the web
receiver saved its accounting receipt. The later recorder required a
local receipt directory. A replacement web receiver could lose the only
remaining report when the database write failed.

**Expected behavior**

The Runner retains unaccepted structured usage. Postgres owns accepted
receipts. Repeated delivery preserves one receipt for each source report
and one charge for the run. Missing usage keeps accounting pending.

**Steps to reproduce**

1. Start a supported built-in native remote Runner.
2. Make the receipt database insert fail after the provider reports
usage.
3. Replace the web receiver and its local directory.
4. Reconnect the same Runner and inspect the saved receipt and ledger.

**Paperclip version or commit**

The initial investigation used
`ebd05e9f4c88c66af7473db86bbaacfd1544aa0a`.

**Deployment mode**

A web server with a remote native Runner and shared Postgres.

Related work: #18327 owns output logs and provider traces. This change
has no dependency on its S3 export path. #18031 covers interrupted Codex
receipt recovery. #18005 covers legacy spool reads. #17516 covers Codex
stop-boundary retention.

## What Changed

- Add native producer receipt delivery through the existing Runner
callback before transport acknowledgement.
- Reuse `run_usage_receipts`, stable source sequences, and deterministic
report identities. Reject conflicting replay and retry a lost commit
response with the same receipt.
- Restore per-turn usage from structured receipt facts. Preserve
provider turns that share one PRP envelope turn.
- Bind retained warm transport callbacks to the current run authority
epoch, allowing old attachment control acknowledgements while preserving
accounting ownership.
- Persist Codex session baselines and cumulative totals in the existing
provider checkpoint. Mark qualified whole-run deltas, preserve them
across resume/restart/attachment, and leave old unmarked reports
incomplete and unpriced.
- Normalize the bounded final usage tail before the terminal event.
Retain later increases for explicit reconciliation, block further
attachment, and fail an affected successor without changing its
baseline.
- Complete runs from the accepted immutable receipt and its exact saved
rate-card amount; preserve existing live-budget enforcement.
- Skip the local receipt recorder for supported built-in native remote
Runner execution. Keep local, legacy, and external Dot/Muse behavior
unchanged.
- Keep pricing, reservations, ledger settlement, source fencing, and
budget holds with their existing owners.
- Put the actual Runner integration test in the existing Rust-cached
native test lane. Build before opening Postgres and give cold
compilation its own bounded budget.

## Verification

- Fresh Greptile review is 5/5 on
`e7376a50c8162770da1d581ecf25c8cffac64520`, with no unresolved findings.
Parent and independent peer review approved the final changes.
- Real PostgreSQL 18.6 and a real Rust Runner exercise failed receipt
insertion, receiver-directory loss, replay from the same producer, and
exactly one 25-cent ledger charge. The actual accounting spool path
stays absent. Optional logs/traces are disabled. The provider is
controlled; no paid request is made and the fixture never pre-saves the
expected receipt.
- Producer checks passed 32 usage/provider tests,37 terminal controls,
corrected completion, all 3 previously failing exit cases, and both full
transport goal-continuation cases. Rejected active-goal completion
retains its 120-token tail before failure. Baseline 100→successor150→33
duplicate old snapshots→old120 retains explicit incomplete
reconciliation evidence and positive budget exposure.
- Heartbeat executor checks passed 982/982. PostgreSQL tests preserve
exact 1.002 USD pricing, the 100.2-cent ledger amount, budget holds,
source takeover, partial/final receipts, cost-only corrections, equal
rate-card replay, and stale-completion interleaving. Newer incomplete
usage remains pending rather than settling an older snapshot.
- Runtime replay and strict usage-schema checks passed 2/2; generated
contracts and Rust formatting pass. Test-partition contracts passed
32/32.
- [Final combined-head
evidence](https://github.com/paperclipai/paperclip/pull/18354#issuecomment-6531526158)
records full workspace typecheck/build and 41/41 accounting tests
against all five cloud PR heads, including this final accounting commit.
It includes commands and evidence limits.
- Exact-head CI is green: 53successful checks, 6intentional skips, and
the legacy Snyk status passed. Typecheck, build, Runner, server,
browser, and aggregate gates pass. Runner Vitest1/2 initially failed an
unchanged mocked Antigravity login fixture; its focused case passed
locally, then one unchanged job retry passed 131 files/1995 tests,
including all 11 Antigravity tests. The initial failed attempt remains
recorded in CI.

Initial local attempts exposed the host SysV semaphore limit and
corrected harness path, IPC readiness, and queue-counter defects. A
temporary test loader selected an existing POSIX-semaphore PostgreSQL
18.6 build without changing repository dependencies. An optional
expanded debug provider run was interrupted at its unrelated 8192-turn
rollover stress case; no full-file local pass is claimed. Required
failure cases were run directly, and the full Runner CI remains
required.

## Risks

- The guarantee covers built-in native remote Runner execution. Local
native execution, legacy adapters, external Dot/Muse execution, and
server-originated model calls retain their existing contracts.
- This does not provide traffic switching or general web-server
failover. The existing controller identity, checkpoint, and generation
gates still apply.
- The receipt JSON gains optional structured producer facts. No schema
migration or accounting S3 spool is added. Text output and raw trace
payloads are excluded.
- Codex accounting authority requires a Runner artifact built from this
provider baseline implementation and qualified by digest. Update
receivers and strict usage-schema readers before releasing that Runner;
PRP does not negotiate this payload field. Existing unmarked Codex
reports remain pending/unpriced. No deployed Runner artifact is claimed
fixed.
- Usage arriving beyond the bounded terminal tail may require manual
reconciliation or a fresh session. Its evidence remains in the existing
producer checkpoint/outbox; no adjustment ledger or recurring scan is
added.

## Model Used

OpenAI `gpt-6.1-sol` assisted with the implementation, tests, and
documentation through code execution and repository tools. The context
window size is unavailable.

DottaandPaperclip dbff3747b8 feat(server): persist run logs and provider traces in S3 (#18327)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Operators use run logs and restricted provider traces to inspect
agent work.
> - Local log and trace files depend on the web server's persistent
volume.
> - That dependency prevents overlapping volume-backed Railway
deployments.
> - This PR reuses the instance S3 store for batched log and trace
payloads with conditional publication.
> - Existing Postgres rows retain their contracts; native export
recovery reuses events already committed before Runner acknowledgement.
> - S3-configured servers automatically copy and verify retained history
before a later deployment cutover.

## Linked Issues or Issue Description

**Subsystem affected**

Server run logs, restricted provider traces, storage providers, and
migration tooling.

**Problem or motivation**

Replacing the web server and its disk must preserve committed log output
and retained traces. The current S3 mirror can repeatedly upload a
growing file. Moving those payloads into Postgres would add database
writes, WAL, replication, and backup work.

**Proposed solution**

Reuse the existing instance storage configuration, S3-compatible
provider and credential chain. Store new run logs under run-logs/ and
opted-in raw traces under provider-traces/, below the existing prefix.
Cloud keeps its existing bucket and bucket-scoped credentials per stack.
Add no new configuration switches. Store immutable payload segments and
bounded binary range indexes directly in S3. Publish each batch with an
ETag-conditional head. Keep existing database ownership and lifecycle
records. Recover canonical native exports from their existing validated
control event source, checkpointing export progress in S3. Add no new
payload writes to Postgres. Preserve local defaults and migrate settled
history with verified byte counts and digests.

**Alternatives considered**

Postgres payload chunks add control-plane load. Repeated whole-file
mirrors amplify transfer work. The first index prototype left superseded
index nodes; the final binary index keeps all normally published nodes
reachable.

**Roadmap alignment**

This is a storage prerequisite for replacing the main web/API server. It
does not enable deployment overlap, detach a volume, or change native
Runner protocol acknowledgements. The maintainer approved this
implementation scope. ROADMAP.md has no duplicate implementation item.

Related PR: #16770 improves the existing in-flight mirror. This PR
preserves that legacy backend and uses the existing instance S3 profile
for new journals.

## What Changed

- Automatically select S3 segments for new logs and opted-in traces when
instance file storage uses S3. Reuse bucket, endpoint, region, prefix,
path style and credentials. Remove separate backend switches. Keep
local-disk instances local.
- Share the existing storage configuration resolver with product files.
Preserve config-file settings, environment precedence and the existing
root prefix. Keep pre-existing run-log mirror settings for legacy
history.
- Add bounded buffering, conditional ownership fencing, immutable range
reads, stable byte offsets, and completion hashing.
- Dispatch all existing log consumers through the recorded backend.
Coalesce output progress writes and publish live log messages after
storage receipts.
- Recover interrupted canonical native exports from their existing
durable source. Exclude separate credential, cleanup, and reprojection
records. Replay missing callback ranges and deduplicate late delivery.
Repair settled archives after controller lease expiry. Bound shared
repair work and stop it when all readers cancel. Serve the published
prefix when best-effort repair fails.
- Add encrypted optional trace channels, replacement reads, durable
deletion tombstones, and deadline-driven local/external expiry cleanup
independently of heartbeat scheduling. Stream historical source and
remote verification. Propagate worker cancellation through trace open,
conditional-write probing, upload, restore and reads. Fence deletion
even before the first object head exists; abort and drain owned
captures.
- Retry transient storage errors, distinguish 409 from failed
preconditions, and backpressure bounded log admission. Track interrupted
trace imports explicitly so ordinary local deletion stays independent of
S3.
- Automatically migrate retained history through the existing delivery
coordinator. Process one log and one trace per batch. Retry unresolved
history with backoff and stop scans after completion. Keep the
inventory/import command as optional diagnosis and repair. Verify source
and remote bytes before switching references. Verify finalized native
size and digest before setting its export cursor. Require ordered source
coverage when completeness metadata is missing. Preserve original trace
expiry. Block active, missing, corrupt, and unproven sources.
- Preserve identity and run-secret redaction in live and recovered
native logs. Register runtime log redaction secrets once through the
existing encrypted registry. Keep agent private keys in their existing
owner.
- Add storage, migration, retention, UTF-8, and route-privacy coverage,
plus operating documentation and qualification tooling.
- Add no schema, payload table, per-record SQL, production dependency,
or lockfile change.

## Verification

- Final fixes at `b3a44c898e` passed all 116 selected startup,
retention, attribution and cancellation controls. The disabled-scheduler
cleanup and concurrent-repair defects reproduced red before the fixes. A
timed-out repair still prevents later storage reads.
- The merged source passed 124 storage and real-Postgres Cloud
configuration tests. These include automatic history migration, existing
environment/file vault keys, source-directory removal, five real-SDK
stalled-request cancellation cases, shared capability-probe cancellation
and multi-chunk trace ordering. Saved Cloud S3 settings work after the
legacy config file is gone.
- Workspace typecheck and full build passed at the merged parent
`19f702d780`. Server typecheck and build passed again at `b3a44c898e`.
- Actual app acceptance: finish a process-agent run through the normal
API, stage its retained local-file input, then restart. Automatic
migration reports one migrated item and zero blockers. Remove the
original web home and restart at `b3a44c898e` with an empty home, the
existing S3 profile and the existing vault key file. The normal log API
preserves all five producer lines and exactly 788 bytes, with SHA-256
`74d9ae469da28bfe89b9b50a0e132aec24fe9e6d686496ed5e4ffa6167151036`. No
log-specific storage settings are present.
- Actual expiry acceptance: with heartbeat scheduling disabled, a trace
remains unexpired after startup and later reaches its fixture deadline.
The worker marks the row deleted and tombstones both S3 channel heads.
The retained run log stays byte-identical. The process fixture emits no
provider protocol frames, so nonempty encrypted payloads are qualified
separately through the real SDK round trips.
- Isolation tests use identical run identities in two stack buckets.
Cleanup in one existing prefix leaves another prefix, another company
and product files intact. Read-only Cloud source inspection confirms a
bucket and bucket-scoped credentials per stack. Four existing Cloud
storage environment-contract tests passed. No Cloud provisioning changed
and no new live vendor permission probe was performed.
- Earlier qualification passed 1,014 affected storage/native tests and
27 privacy-route tests with isolated Docker Postgres. An abrupt process
test commits 1,000 records, receives receipts, dies by SIGKILL and loses
its directory; another process reads every byte and continues. The real
Rust Runner experiment acknowledges 32 records while the export cursor
is zero, then continues the same Runner PID after controller loss. All
64 records export once with exactly 64 existing control rows. Repeated
snapshot/Stop commands completed in 162/81 ms.
- Emulator workload: 1,000 burst records used two batch PUTs. Eight
steady streams produced 240 records with 104 conditional PUTs and 72
GETs over 6.9 seconds. These are synthetic operation counts, not fleet
sizing or provider prices.
- Failure evidence is retained. Compact native events over 64 KiB,
missing file-key support, disabled-scheduler retention and repair
failure handling all reproduced before their fixes. Fixture repairs
addressed cold module setup, localhost/IPC permissions, the S3
bucket-name limit and a mode-0700 crash-test directory. Full local `pnpm
test:run` was stopped after host PostgreSQL semaphore exhaustion;
affected suites used isolated Docker databases instead. Native package
library symlinks were restored with the package's standard hydration
helper.
- The `19f702d780` browser session-recovery case timed out while saving
a task title. All eight browser shards passed on `b3a44c898e`, including
that case, with no UI behavior or assertion change. Fresh-head CI passed
at `b3a44c898e`: 55 successful checks, three skipped checks and one
neutral check. The branch is conflict-free.
- Map and module-boundary checks passed. Current-head Greptile is 5/5
with zero unresolved review threads.

Reproduce the opt-in storage suites with
`PAPERCLIP_LOG_TEST_S3_ENDPOINT` and a dedicated
`PAPERCLIP_RUN_EVIDENCE_MIGRATION_DATABASE_URL` ending in `_test`. See
`doc/run-evidence-storage.md` for operating limits, automatic migration,
optional diagnostics and rollout qualification.

## Risks

- Keep the existing per-stack bucket, prefix and vault key stable across
replacements. Relocating that storage is a separate whole-instance
operation.
- This release automatically changes new log storage for existing
S3-configured instances. Local-disk instances remain local. Canonical
native source replay is qualified with a deterministic real Runner;
actual remote execution and production-provider qualification remain
rollout gates. Generic server-only diagnostics and optional raw trace
tails without a surviving source can be incomplete after a crash. This
does not establish full zero-downtime deployment.
- Before deploying this release, qualify the actual S3 provider. It must
enforce conditional writes and pass read, version, deletion, workload,
and latency qualification. A capability probe rejects providers which
ignore preconditions. Moto is emulator evidence only.
- Dirty output is bounded and unconfirmed until S3 publication. Storage
failure leaves persistence incomplete while task results and usage can
settle.
- Trace expiry is not yet represented by Cloud's external wake contract.
Outstanding trace deadlines conservatively block sleep.
- Automatic history copying requires the original source volume. Keep it
until all retained resources pass verified import and clean-filesystem
reads. Stop old binaries from creating new local-file runs. Missing or
corrupt history remains blocked and visible in server logs. Rollback
requires a compatible reader against the same external state. Ordinary
object deletion does not erase retained historical object versions or
backups.

## Model Used

OpenAI Codex, `gpt-6.1-sol`, with reasoning, tool use, code execution,
and browser verification. The runtime did not expose a context-window
size.

DottaandPaperclip 6f278dd6d7 fix(runtime): settle recovery lease and connection lifecycles (#18167)
## Thinking Path

> - Paperclip manages AI agents and their work.
> - A remote runner can survive a controller restart.
> - Recovery renews its execution lease during slow preparation.
> - The native executor then shares that renewal timer.
> - Preparation kept its reference until all finalization finished. A
tick after lease release treated completion as ownership loss and
detached the retained runner.
> - A Linux continuity test also found that buffered wire events could
arrive before their connection was registered. Cleanup then kept a
completed promise under an undefined key and never finished.
> - This pull request transfers renewal ownership after execution
acquires its reference. It also registers each connection before wire
callbacks can run.
> - Recovered turns can complete, retain the warm runner, and settle
connection cleanup.

## Linked Issues or Issue Description

**What happened?**

A recovered remote run could complete, release its coordinator lease,
then detach during instruction collection. The next turn could find the
old runner still using the ingress port. Recovery then stopped because
it could not prove process ownership.

**Expected behavior**

Preparation keeps the lease alive until execution owns renewal.
Execution stops renewal before releasing the lease. Actual ownership
loss still detaches the runner. Buffered wire callbacks must use the
registered connection, and cleanup must finish.

**Steps to reproduce**

1. Recover an in-flight remote runner after a controller restart.
2. Let the recovered turn complete.
3. Hold instruction collection open through the next lease renewal tick.
4. Send a follow-up that needs the retained runner.

Related: #17439 introduced remote controller recovery. #18011 preserves
checkpoint authority through warm preparation. This change fixes the
lifetime of preparation's renewal reference.

## What Changed

- Pass an internal lease-acquired callback from recovery through
heartbeat dispatch.
- Release preparation's renewal reference after the executor registers
its own. Keep final cleanup for exits before dispatch.
- Add a PostgreSQL regression for completion while finalization is still
pending. Cover callback forwarding, acquire-before-release ordering, and
failure before dispatch.
- Register the authority connection before subscribing to wire events.
Handle an immediate close before accepting buffered data.
- Add regressions for a message or close delivered during subscription.
- Extend Linux continuity coverage with preparation renewal and delayed
instruction collection after recovery.
- Update the continuity guide and session verification recipes.

## Verification

- The new recovery regression failed before the fix because renewal
detached the runner after lease release. The 76 recovery, renewal, and
dispatch tests then passed. The final ordering and early-exit checks
passed again after replacing fixed sleeps with controlled interval
ticks.
- Both buffered-wire regressions failed before the connection fix. All
170 control-plane tests passed afterward. Existing tests cover stale
authority, ownership loss, pending operations, and closed ingress.
- Linux ARM64 acceptance passed at
`a7daefacceb8bd994d0b79d284cdf54f3e3829d1`, with Node 24.19.0,
PostgreSQL, the real Rust runner, TLS ingress, and a deterministic Codex
protocol fixture. The test interrupted the first turn, recovered it,
held finalization open for a renewal interval, and completed two
follow-ups. It retained one provider process, three turns in one
history, and the same runner identity. Final suspension and connection
cleanup completed. The ordinary warm-reuse case also passed three turns
with one provider process.
- Earlier Linux attempts completed the turns but hung during cleanup. A
debugger found a fulfilled promise keyed by an undefined connection. The
regression reproduces that defect. One later setup attempt timed out
while staging an unstripped 373 MB debug binary. The passing run used
the same binary with debug symbols removed.
- Reproduce Linux acceptance with the `same-server` case in
`doc/testing-native-remote-continuity.md`.
- `pnpm -r typecheck`, `pnpm build`, map validation, and `git diff
--check` passed at the final revision. The full local `pnpm test:run`
command was attempted, but the serial run had not finished after 13
minutes. It was stopped after the equivalent CI lanes passed. It is not
counted as a full local pass.
- Greptile and the Paperclip review both scored the final revision 5/5
with no findings. All Runner verification lanes passed. The first CI
attempt hit timing failures in voice recovery, agent YAML configuration,
and the task-title outage browser test. The full YAML and voice-recovery
files passed locally (88 and 19 tests). These paths were unchanged and
passed on the prior revision. All three passed on the single retry.
Final current-head status: 55 successful checks, one neutral check, and
two skipped Storybook checks. No pending or failed checks remain.
- Live Daytona/model acceptance and recovery of the hosted task remain
unverified. This PR does not deploy the change.

## Risks

- Releasing preparation before execution starts renewal could leave a
gap in authority. The callback runs after the executor registers its
reference.
- Preparation errors must not leak renewal. The recovery promise retains
idempotent final cleanup.
- Wire callbacks can run during subscription. Message and close
regressions check that registration is complete before either callback
runs.
- No schema, API, model, permission, lease duration, or retry policy
changes.

## Model Used

OpenAI GPT-6 through Codex, with reasoning, repository tools, code
execution, and browser diagnostics. The exact serving model identifier
and context window are not exposed in this session.

DottaandPaperclip 567c043b17 feat(server): expose bounded hot-upgrade readiness (#18037)
## Thinking Path

> - Paperclip coordinates agent work and keeps its authority in the
server.
> - Remote native runners can preserve execution through a server
replacement.
> - Deployment operators need evidence that current runs support that
recovery.
> - Process-local drain counters do not establish this fact.
> - This PR adds an optional, operator-only readiness observation from
existing records.
> - A deployment consumer can use that report while the existing runtime
retains recovery authority.

## Linked Issues or Issue Description

Refs #17439.

**What happened?**

A deployment cannot distinguish recoverable remote native executions
from runs that require a task drain. The existing status endpoint
reports only process-local counts.

**Expected behavior**

An instance operator can request a bounded readiness report without
stopping admission or exposing checkpoint material. Missing ownership or
persistence evidence must prevent readiness. Ordinary status reads must
keep their current cost.

**Steps to reproduce**

Run a remote native task. Read the task-drain status. It reports active
work but supplies no recovery eligibility. Deployment code therefore has
no affirmative signal to select an active-run handover.

## What Changed

- Add `GET /api/instance/task-drain?upgradeReadiness=1` for instance
administrators and existing Cloud control callers.
- Return aggregate eligibility from current run identities, controller
leases and bound opaque checkpoint headers. Unknown work, pending
admission and incomplete reads prevent a positive report.
- Bound the explicit read to 1,001 rows, encrypted headers of at most
256 KiB each and 8 MiB total, and a two-second SQL statement timeout in
a read-only transaction. Keep ordinary status reads in memory.
- Add PostgreSQL, count-transition and route authorization tests. Update
the API contract, operator docs and access maps.

## Verification

- All seven readiness cases pass against an isolated PostgreSQL 18
fixture. They cover missing checkpoints, legacy adapters, missing
process/session identities, foreign owners, expired leases, missing
lease tokens, failure state and in-flight work. The positive SQL fixture
uses the real Runner checkpoint writer and encryption. Regular sandbox
workspace identity and plugin environment-lease identity are tested with
independent IDs. Stopped/released/undispatched plugin tasks and every
mismatched identity field are rejected. Local/legacy/malformed/oversized
or mismatched headers are rejected. A held PostgreSQL table lock proves
the two-second cancellation budget, rollback/connection release and
unrelated query responsiveness.
- All 123 focused readiness, instance-settings and Cloud control
assertion tests pass, including operator-only access and no readiness
read on ordinary status requests. Runner’s 168 checkpoint tests pass.
Runner and server typechecks pass after review fixes.
- Workspace typecheck, full build, module-boundary and map checks passed
locally before the master rebase. Current-head GitHub CI is now green,
including typecheck, build, all grouped/serialized server and Runner
tests, browser shards, policy and review-dispatch checks. Greptile
completed cleanly at 5/5 for `f15fb0c7e9dfb975090cd5d791a1c8e6701275f8`;
all actionable threads are resolved.
- The broad local test run was stopped after the macOS embedded
PostgreSQL fixture failed to bootstrap. The SQL test was then run on the
isolated PostgreSQL fixture. No assertion or timeout was weakened. One
unrelated existing route test exceeded its 15-second limit under
concurrent local builds; it passed on one isolated retry and the
subsequent whole route suite passed.
- Hosted active-run upgrade acceptance has not run. This PR supplies an
observation; it does not change rollout policy or establish live
continuity by itself.

## Risks

This is an instance-wide observation, so company members and agent keys
must not receive it. A readiness snapshot can age as work changes;
shutdown and startup retain their existing execution authority and
fencing. The report does not validate a replacement artifact or
authorize a schema migration. It decrypts only bounded headers through
the checkpoint owner and delegates format/identity inspection to Runner;
full journal restoration and physical sandbox authentication remain with
recovery. No migration, recurring query, new checkpoint write or wire
protocol change is included. The additive Runner header inspection
contract reuses its existing parser.

## Model Used

OpenAI Codex, based on GPT-6, with reasoning, source inspection, tool
use and code execution. The host does not expose the exact serving model
ID or context-window size.

DottaandPaperclip 09ad9adce2 feat(server): adopt running remote agents through durable controller checkpoints (#17439)
## Thinking Path

> - Paperclip must keep admitted remote work alive while its main server
is replaced.
> - Runner owns recovery mechanics and exposes opaque checkpoints
through #17097.
> - The server owns company scope, encryption, Stop, tool authority and
execution ownership.
> - A successor must prove current ownership before it adopts the
original execution.
> - Checkpoint bursts must also leave capacity for normal requests and
lease renewal.
> - This PR persists and adopts that authority through the existing
runtime boundaries.

## Linked Issues or Issue Description

**What existing behavior does this improve?**

Remote agents retain the original execution during a bounded main-server
outage.

**Current behavior**

A server restart can lose the controller's local state and connection.
An unsafe replacement could repeat a turn or an uncertain mutation.
Checkpoint writes in the request pool can also delay ordinary requests
during an aligned burst.

**Proposed behavior**

Restore encrypted control records from Postgres and adopt the original
runner under a fenced lease. Recover known tool receipts through current
tool authority. Give control checkpoints a shared pool capped at two
connections per database owner.

Depends on #17097. Successors are #17455 and #17456. Qualification and
presentation remain separate review slices.

## What Changed

- Add company/run-bound encrypted checkpoint records and migration 0394.
Keep the SQL idempotent after renumbering against current master.
- Recover startup and expired ownership through native runtime and
heartbeat. Preserve the sandbox lease, admitted runner artifact, harness
configuration, native session and active turn.
- Keep Stop, finalization, preparation ownership and stale-writer
fencing transactional. Preserve graceful detach and natural crash
takeover.
- Recover committed tool receipts through the existing authority.
Reauthorize reads and hold uncertain mutations.
- Bound startup retention with the existing coordinator and preserve
zero idle scans.
- Share at most two checkpoint connections per database client. Keep
application and liveness capacity separate. Close the checkpoint pool
during shutdown; late writes cannot reopen it.
- Count SQL across both application and checkpoint clients. Prove
request/liveness progress, command recovery and failure after pool
shutdown with real Postgres.

## Verification

Project creation recovery now uses the existing project activity receipt
owner. It retains authenticated input normalization, fingerprint checks
and current run authority after the receipt lock. An absent receipt
returns no result before mutation. The new lost-HTTP-response and
no-effect regression uses real API routes and Postgres. The seven
transport cases pass locally. This Mac skips all 20 database cases. On
current source `5de803c2cd`, Linux [job
122593415890](https://github.com/paperclipai/paperclip/actions/runs/40620576702/job/122593415890)
executes all 20 project-tool cases successfully (9.480 seconds),
including the committed-project lost-response regression. Its shard
passes 1,627 cases with three unrelated skips. Server typecheck passes.
The transport regression initially has two failures; a subsequent
incorrect expectation about schema defaults was corrected before the
final pass. Ordinary execution adds no checkpoint writes or recurring
work.

Current candidate `5de803c2cd` includes the project-creation receipt
recovery fix and master `2cd747d1b6`. Migration 0394 retains the prior
idempotent checkpoint DDL. Every master SQL file and journal entry is
preserved. Snapshots 0390–0394, migration checks and server typecheck
pass.

The ordinary warm-turn regression fails on its second turn before
`a219ab51ad`. After correction, three completed warm turns select the
correct prior checkpoint and preserve the original session. All 288
provider-wiring cases pass. The control plane, external persistence
callback, identity rotation and filesystem are real; the backend and
database-load seam are scripted. The 13 warm admission/configuration
variants also pass after final master integration. This does not qualify
an underlying harness.

At current source `5de803c2cd`, Linux [job
122593415907](https://github.com/paperclipai/paperclip/actions/runs/40620576702/job/122593415907)
passes all 940 native-session-executor cases (61.431 seconds), including
the warm external-checkpoint behavior; the shard passes 2,358 cases with
one skip. Current [Runner job
122593415475](https://github.com/paperclipai/paperclip/actions/runs/40620576702/job/122593415475)
passes the native recovery lane: 115 passes and five container-only
skips, including the encrypted restore guard, fresh preparation (63.189
seconds), blocked claim lock (1.226 seconds) and recovery beyond 101
blocked owners (3.897 seconds). The first lane passes 2,215 cases with
one skip. The SQL cost test reports zero idle and streaming SQL for both
output volumes; this is component evidence, not a production capacity
claim. At prior candidate `1ff7bb44f4`, Linux job 122549307215 passes
all 938 native-executor cases, including the three-turn
external-checkpoint regression. Job 122549306469 passes the native
recovery lane with 115 passes and five container-only skips, including
the encrypted-restore session guard, fresh preparation (63.664 seconds),
claim-lock contention (3.961 seconds), and 101-owner recovery (3.824
seconds). This Mac skips the real-Postgres suite. The earlier full local
executor attempt has 921 passes and 16 failures during embedded-Postgres
initialization before assertions. The original fixture collisions and
their corrections remain recorded.

At earlier candidate `8fbe62b41d`, server shard job 122535673841 has
3,876 passes, one failure and one skip in an unchanged expiry-worker
retry/drain timing test. The same server/database tree on qualification
source `b64cac6951` passes all 20 expiry cases and all 3,877 shard
cases. The single diagnostic retry, job 122541891915, passes all 20
expiry cases and all 3,877 shard cases (one skip). No assertion was
weakened. The original failure remains recorded and its exact timing
race is not proven. All Actions checks and legacy status passed on
`8fbe62b41d`, with completed Greptile 5/5 and no open feedback. The next
candidate `1ff7bb44f4` also passed all Actions checks and Greptile 5/5.
Its Paperclip Review remained queued before the new master conflict
required integration. The new candidate needs fresh exact-head CI and
reviews; old checks do not qualify it. Migration generation is
checkpoint-only, all master SQL and journal entries remain unchanged,
and migration checks, server typecheck and all 13 warm-owner variants
pass after integration. The first migration check was blocked by TSX
sandbox IPC; its permitted repeat passes. The first warm-test command
used an incorrect path and ran no tests; the corrected command supplies
the 13-case receipt.

All 16 database pool-lifetime/options/teardown cases pass after granting
loopback permission; the first batch had two EPERM failures and 14
passes. Earlier semantic-tool/HTTP recovery, adoption, encryption-batch,
zero-streaming-write and idle-SQL receipts remain source-attributed in
the [qualification
record](https://github.com/paperclipai/paperclip/blob/2ff66f57da0da35bac1c19a2366ea4b84d87a986/doc/plans/2026-10-22-hot-upgrade-qualification.md).
That record retains earlier assertion, setup and cleanup failures and
their corrections. No failed gate is waived.

The historical 300-session component campaign passes four after phases:
steady read p99 is 107–108 ms at 500 reads/s and 100 writes/s;
aligned-burst read p99 is 103–105 ms after the bounded pool, versus
584–689 ms before. This comparison isolates the persistence corrections.
It does not measure the final stack's hosted active-agent capacity. The
hosted zero-agent API pair leaves SQL and CPU essentially unchanged, but
both arms fail absolute latency gates and candidate peak cgroup memory
fails its gate. The active-agent/viewer matrix, different-artifact
upgrade and rollback remain open.

Run `PAPERCLIP_TEST_DATABASE_URL=<owned-disposable-postgres> pnpm
--filter @paperclipai/server exec vitest run
src/services/native-runtime/native-runner-restart-recovery.integration.test.ts`.

Previous head `f2db8a6568` had one failed workspace setup gate: [job
122555672441](https://github.com/paperclipai/paperclip/actions/runs/40608984238/job/122555672441)
passes all 4,169 UI tests and 285 CLI cases (one skip), but the company
import/export suite reaches its 30-second health deadline during doctor
startup. Its output does not reach the server-start step. The CLI,
server, database, shared, adapter and plugin trees are identical on
qualification source `a866619d7b`, whose [job
122555886663](https://github.com/paperclipai/paperclip/actions/runs/40609057937/job/122555886663)
passes that fixture and all 286 CLI cases. The one diagnostic retry,
[job
122561057225](https://github.com/paperclipai/paperclip/actions/runs/40608984238/job/122561057225),
passes the formerly failing fixture and all 286 CLI cases. All Actions
checks and legacy status on `f2db8a6568` pass. Its exact-head Greptile
completed at 5/5 with no open feedback. The current integrated head
requires fresh checks and a completed Paperclip Review before merge. The
original failure remains recorded; its exact timing cause is unproven. A
repeated failure requires investigation and repair rather than another
retry.

All current-head CI, legacy status, exact-head completed Greptile 5/5,
resolved feedback and ordinary GitHub merge eligibility remain required
before merge.

The latest integration preserves master’s published Copilot v70 profiles
and every published migration. Checkpoint migration
`0394_conscious_whizzer.sql` was generated with `pnpm db:generate` and
retains the prior idempotent DDL. The Runner vendor rebuild and replay
parity checks pass. Server typecheck and all 13 warm-owner variants pass
after that rebuild. The imported report-lock patch is byte-identical to
master; its intentional patch-context whitespace is retained, and the
feature delta passes whitespace checks. No hosted experiment was run.

## Risks

The pool adds up to two active connections per instance, shared across
agents. Checkpoint delivery can wait behind that bound; it still
requires its commit. Steady component-test Postgres CPU rises by about
1.7 percentage points of a two-CPU allocation. These corrections do not
remove the stack's control and renewal writes. The migration and key
must survive replacement. Fresh-database tests and local load do not
establish different-artifact hosted upgrade or rollback continuity.

## Model Used

OpenAI GPT-6 through Codex, with reasoning, repository tools and code
execution. The runtime does not expose a more specific model ID or
context-window size.

DottaandPaperclip db11d899cf fix(native): recover remote sessions while preserving warm runs (#16451)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Native agents keep remote processes and conversation history across
warm turns.
> - A completed turn can leave handoff authority only in controller
memory.
> - Losing that controller can block a follow-up even while its sandbox
survives.
> - This pull request verifies durable ownership and reconnects the
exact prior process before handing it to the next run.
> - Healthy follow-ups stay warm. Recovery preserves saved work without
replaying a completed turn.

## Linked Issues or Issue Description

**What happened?**

A remote warm turn can finish without suspended backup authority. A
replacement controller rejects that prior owner even when its exact
process and completed checkpoint remain. A single unavailable identity
probe can also stop an otherwise valid reattachment.

**Expected behavior**

Keep healthy follow-ups warm. Recover a completed session after proving
that its controller stopped and that the successor holds current
authority. Reuse compatible processes; otherwise save and resume the
conversation. Retry unavailable identity reads within one shared
deadline.

**Steps to reproduce**

Use `doc/testing-native-remote-continuity.md`. Its Linux cases execute
real turns through PostgreSQL, TLS ingress, and the Rust runner. They
kill a separate controller process, recover old checkpoint metadata, and
change process configuration. The provider is deterministic.

Related: #16432 and #16441 fix live warm-owner handoffs. #16341 adds
recovery diagnostics. #14695 covers provider process retention.

## What Changed

- Preserve warm process reuse between healthy remote turns.
- Verify a committed prior result, stopped controller, matching
checkpoint and sandbox, and current task/coordinator ownership before
recovering an orphaned warm session.
- Reconnect through the prior run route, then use the existing
authenticated run attachment to change authority.
- Persist a process-configuration digest. Close and save recovered
sessions when old or changed configuration cannot support reuse.
- Retry unavailable state, marker, and process reads within one
30-second deadline. Keep signals and definitive identity failures
single-attempt.
- Record closed recovery diagnostics, including unreadable or malformed
saved state.
- Retire the recovery-only ownership check after verified attachment, so
later warm turns use their current authority.
- Add real-process Linux regressions and refusal controls.
- Expose the existing source-only file-recovery form for retained native
holds, with the same board authority, evidence, and exact stop-receipt
requirements as legacy holds. Recording recovered files does not change
task status or replay a run.

## Verification

- `pnpm -r typecheck` passed; the server check was repeated for the
third-turn fix.
- `pnpm build` passed after the final UI change. The UI typecheck, token
gates, and map checks also pass.
- Four Linux continuity cases passed: warm reuse, controller loss,
legacy checkpoint metadata, and changed configuration. Each creates one
conversation and starts exactly three turns, including a healthy
follow-up after recovery. The fixture uses expired prior leases; the
third turn keeps the runner and provider processes.
- Greptile caught the retained recovery gate; the third-turn regression
now covers it. An initial test omitted the heartbeat’s saved input and
left a test process after failure; the fixture was corrected and its
disposable container reset before the passing run.
- The current focused executor/restart group passes all 749 tests,
including the original failure classifications.
- Native file-recovery and UI tests pass (52 tests), including blocked
tasks and both native and legacy holds.
- After merging current master and retaining its equivalent CI
expression check, the CI policy tests pass (15 tests) and all four
three-turn Linux continuity cases pass again on
`dec418ae55ff21b4fb067132613658cce445f181`.
- `pnpm test:run` completed its general server group with 20,572 passes,
103 skips, and three failures: the skill-audit child process and two
HTTP test timeouts. The same three suites then passed in isolation (89
tests) without code changes. That local command stopped before later
groups; the complete final-head CI, including general, serialized,
Runner, build, and browser gates, is green.
- Greptile reviewed the combined head
`dec418ae55ff21b4fb067132613658cce445f181` at 5/5 with no actionable
findings; both earlier findings are resolved. All final-head CI gates
and the security scan passed. Staging deployment and retained-incident
disposition remain deployment acceptance work.

## Risks

- Recovery requires exact durable evidence. Live conflicting
controllers, replacement sandboxes, Stop/pause, and uncertain effects
must remain blocked.
- After controller loss, tool-contract or process-configuration changes
can restart the provider. Normal healthy follow-ups retain their
processes.
- The new idle-recovery path has Linux fake-provider evidence. Live
Codex/OpenCode and retained quarantined-state recovery still need
staging qualification.
- No database schema, telemetry, or runner protocol changes.

## Model Used

OpenAI GPT-6 through Codex, with reasoning, repository inspection, code
execution, and browser tools. The session does not expose a more
specific model version or context-window size.
