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
receipt SHA-256

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.

Paperclip Native Runner

To add a harness/provider to native Runner, start with create-runner-adapter, the Runner integration playbook, and acceptance/evidence templates. They cover the new Runner integration path; legacy adapters are preserved as a compatibility boundary.

This package is the standalone development boundary for Paperclip's native runner protocol, process supervision, durable transport, provider drivers, and normalized session backends. Rust owns the production runner under runner/; TypeScript provides the control-plane reference, browser SDK, scenario tools, and conformance oracle.

The package includes one coherent set of capabilities: PRP v1 validation and replay, a supervised local runner with a scripted fake harness, durable WebSocket delivery and recovery, qualified Codex, OpenCode, ACPX, Claude Managed, and AWS AgentCore drivers, live session and issue-thread surfaces, a public browser/React SDK, a standalone adapter demo, and a deterministic mock control plane. None of these surfaces imports or starts Paperclip's server, UI, CLI, or production database.

Execution environment lifecycle

RunnerExecutionDriver defines the environment hooks shared by coding harnesses and external bot harnesses. The server's createNativeRunnerExecutionDriver supplies this contract for local, SSH, and sandbox execution. Provider-specific session setup stays separate from environment selection.

Connection registration prepares remote resources and returns the process's connection configuration before launch. Local Runners connect to Core over loopback WS. SSH Runners and eligible sandboxes connect to the configured Core WSS endpoint. Sandboxes with authorized WebSocket ingress listen inside the sandbox; Core connects through the provider endpoint after process dispatch. Ingress selection fails closed and does not fall back to outbound WSS.

The returned activation, readiness, failure, checkpoint, and release hooks feed the existing shared PRP control plane. PRP owns authentication, commands, replay, tool authority, and run transitions. Process ownership hooks provide launch, verified adoption, and durable state access. A lost connection does not prove process termination, and a required checkpoint failure must prevent lease release.

The driver is an in-process interface. Its filesystem paths and process launch specifications are internal to built-in execution; they are not a plugin wire contract. Existing flat transport options remain compatible through this shared interface. This refactor does not add Launcher APIs or change harness capabilities.

An execution owner can supply prepareLaunch, a Runner artifact identity, and process and connection hooks. Core supplies the launch requirements. The owner returns a provider descriptor bound to those requirements. Core checks the policy and assigned resources. See Runner launch preparation for the contract and recovery record.

Connection continuations inspect the harness descriptor's optional toolRefreshOnResume capability. Native Codex, Claude Managed Agents, AgentCore, OpenCode, and qualified Claude/Codex/Grok ACPX profiles expose it; unqualified harnesses leave it false or absent. Changing tools can replace a provider process while retaining the provider conversation. Company, agent, task, workspace, model, instruction, and skill compatibility still gate recovery. An MCP-only assignment change can resume only when the selected harness explicitly supports refreshing tools.

Compact continuation messages include the active completion revision and criterion IDs plus a reminder to obtain an accepted paperclip_finish or paperclip_block result for this turn. Reports from earlier turns do not finish the new turn. Provider final text alone remains insufficient; governed waits and strict native completion validation keep their existing behavior. This reminder changes the resumed model input, not the tool catalog or automatic retry policy.

When recovery needs a fresh conversation, the server supplies a deterministic handoff through a lazy history loader at the fresh attempt boundary. It includes the original request, recent messages, resolved interaction summaries, agent replies, and document excerpts, with source identities and retrieval instructions. Reads and excerpts are bounded; the handoff has a 24,000-byte ceiling and explicit truncation/omission markers. Conversation reset boundaries, deleted messages, source quarantine, and secret redaction apply before model submission. Successful recovery does not fetch or replay the handoff. Legacy adapters advertise supportsToolRefreshOnResume for their selected harness: Claude and Codex CLI/ACP, Grok CLI, Gemini/Kimi CLI/ACP, and Cursor/OpenCode/Pi CLI. CLI adapters using environment tool delivery start each invocation with current endpoints and credentials, including resumed turns. ACP reloads current MCP bindings, including run-scoped credentials, while preserving the conversation; an unqualified/custom harness retains its restart fence. Legacy fresh attempts receive the same bounded handoff, including resume-failure fallbacks. Provider authentication repairs retain their existing fresh-session recovery behavior.

ACPX release declarations

acpx-profiles.json owns the package versions, command/profile digests, and required execution policies used by TypeScript and Rust. It contains no models. After changing it, run pnpm --filter @paperclipai/paperclip-runner generate:acpx-profiles. Normal build and typecheck reject stale generated declarations. Generation also checks installed dependency pins and agreement with Cursor's distribution manifest and immutable release attestation (cursor-contract.json). Cursor's per-platform closure pins are generated from cursor-distributions.json.

Codex startup and browser login prefer the CLI from the installed dependency graph. If that dependency is absent, they use an executable codex from the selected execution host's PATH. An explicit execution command takes precedence, and resumed sessions retain their recorded command. Older or newer CLI versions are allowed. Relative PATH entries use the selected process working directory. Compatibility is established by the actual protocol or login attempt. Missing executables and real protocol failures still return actionable errors. Package identity and executable containment remain checked. Browser login keeps its provider-specific credential home and resolves the installed Codex CLI on 64-bit Linux and macOS independently of the daemon's libc requirements.

Exact dependency pins remain release and ACPX artifact-qualification checks. They make published builds reproducible and verify sandbox artifacts; they do not add a version-number gate to ordinary native Codex startup or browser login.

Release packages retain the pinned Codex JavaScript dependency graph, but do not bundle Codex native binaries. The published manifest declares the official, exact-version platform packages as optional dependencies. npm installs the package for the consumer's operating system and architecture. Those declarations belong to the published server manifest; the bundled JavaScript wrapper delegates platform installation there so npm can keep native and legacy versions separate. The wrapper code and patched ACP bridge stay unchanged. Codex sandbox read roots include the separately installed native vendor resources without granting access to enclosing npm directories or credential homes. This packaging does not change agent defaults or the selected runner of an existing agent.

Every ACPX harness accepts an explicit caller-selected model without a Paperclip model allowlist. The adapter sends that ID unchanged and verifies the provider's effective model before prompting. An incomplete discovery catalog does not block selection; a provider rejection or mismatch fails without choosing a fallback. Qualification model selections live in test catalogs, separately from optional product defaults. The legacy resolved snapshot field qualificationModel contains the caller's selected model; its serialized name preserves recovery identities. Historical profile fixtures remain immutable evidence, not release declarations.

Pi credentials are selected from the explicit run environment and remain session-bound. The native Rust launcher forwards the controller-bound credential names, including custom provider references, without restricting Pi to an OpenRouter credential. Built-in providers can use their usual API-key environment variables. Custom Pi providers are supported through PAPERCLIP_PI_PROVIDERS: a JSON object containing the native models.json provider entries (without the outer providers key). The runner writes that configuration to the private Pi agent directory and binds its digest to recovery. API-key and header environment references are forwarded only from the explicit run environment; command-based credential resolution is unsupported. Select the provider/model ID explicitly in the agent configuration. The bundled ACPX package tests exercise unlisted model selection, rejection, exact acknowledgement, and replay on a loaded connection. Catalog membership and Cursor model-alias expansion do not determine the selected model. Provider activity adapters own native tool identities, evidence, and diagnostic usage projection; the shared driver and sidecar consume those hooks.

Public package surfaces

  • @paperclipai/paperclip-runner — production contracts, clients/backends, PRP validation/replay, canonical catalog/dispatcher, and compatibility check.
  • @paperclipai/paperclip-runner/testing — deterministic mocks plus PRP and semantic conformance kits. Tests and external conformance consumers import this explicitly.
  • @paperclipai/paperclip-runner/evals — versioned native-attempt metadata, fail-closed package/binary compatibility checks, and explicit runnerd artifact resolution for eval consumers.

The package root has no mock or scenario exports. Generic credential-free matrix orchestration lives in the workspace-private @paperclipai/paperclip-eval-kernel; scenario content and provider-backed eval campaigns remain outside the runtime package. See ADR 0001.

The two conformance surfaces intentionally prove different contracts. The existing runControlPlanePortConformance suite checks narrow PRP run/event persistence. CAPABILITY_HIGH_RISK_SEMANTIC_VECTORS and runSemanticConformanceKit compare normalized tool authorization, state, effects, audit, retries, conflicts, redaction, continuation, and terminal decisions. The production adapter stays App-owned and invokes Paperclip's real route/service authorities; it does not copy those rules into this package.

Quick start

Native provider debug-trace correlation uses an incremental index owned by its transport. Pending event lookups read only newly appended bytes, with a 1 MiB read budget per lookup; they retry until the observed suffix is indexed. Partial records remain pending, and trace replacement or truncation invalidates the index. Closing a transport clears its index. Other active transports cannot evict its progress. Records over 64 KiB are skipped by the correlation index without buffering or parsing their full contents; the original trace file retains them. Do not restore a full synchronous trace scan for each pending event: it blocks event delivery and can leave the board showing an active run after the provider turn has already ended.

The package also builds paperclip-runner-acpx-sidecar. This bounded v2 stdin/stdout bridge admits the pinned Claude, Codex, Grok and Cursor ACPX profiles. It validates the exact model, session identity, tool catalog, structured input, and terminal settlement at the process boundary. Copilot and Pi remain gated. Verified distributions are build-owned; no provider accepts an arbitrary executable. See the rich ACP capability report.

If the controller sends assigned MCP tools in the PRP catalog, the sidecar uses its authenticated tool bridge. Isolated provider admission accepts this route without a separate native MCP endpoint. Direct runtime-host callers must supply the native gateway binding unless they select PRP tool delivery and supply the semantic tool bridge. PRP delivery keeps the controller's exact operation names, including compact MCP catalog tools. The selected permission and read-only policies still apply.

Install Cursor explicitly with paperclipai runtime setup cursor; npm installation does not download it. Run setup as the OS user that runs Paperclip (the service account for a managed service). Setup writes to that account's ~/.paperclip/runtimes/cursor/<platform>-<arch>/<closure-sha256>, so a system-wide npm installation can remain read-only. Isolated provider HOME/XDG settings do not redirect this cache. Container images continue to use their packaged assets. Configure a company secret binding for CURSOR_API_KEY or CURSOR_AUTH_TOKEN, select Cursor in the Runner configuration, and select an exact model ID. Agent is the default; Plan and Ask are explicit modes. Paperclip semantic questions are supported. Native AskQuestion and authoritative per-run dollar usage are unavailable. Accepting a native plan ends the planning run successfully while the task waits for the next instruction. See the Cursor release report.

Google Antigravity is an unqualified, pending native ACPX integration. The explicit paperclipai runtime setup antigravity command installs the verified Antigravity ACP 1.4.3 distribution and its owned admission patch on macOS ARM64. It verifies both the official vendor closure and the separately pinned patched closure; npm installation downloads no Antigravity runtime. This setup installs assets only. Global release qualification remains pending and normal execution admission stays closed. An isolated operator can admit one company, exact model, local platform and pinned native closure/profile until a fixed expiry through trusted server startup authority. The candidate supports a managed saved Google subscription; the recorded acceptance reused the same owner's personal default grant and gemini-3.8-flash-low on macOS ARM64. This does not qualify fresh Google consent or the separate API-key route. Google Workspace OAuth does not substitute for a runtime credential. See the integration contract and evidence.

A release includes all four platform daemons and the Linux provider-pack identity from its matching Daytona image. Run stage:release-binaries with a manifest that binds each daemon path and SHA-256, plus remoteProviderPacks: {"linux-x64": {path, sha256}, "linux-arm64": {path, sha256}} for the actual image's provider-pack.json. Assemble these assets after the normal build and include them in the server's vendored Runner output before npm packing. Assembly requires the provider pack's source revision to match sourceRevision and its ACPX profiles and Cursor distribution to match the current source pins. An independently rehashed older pack is rejected. Provider-pack builds replace the installed Copilot platform wrappers with relative launchers. These wrappers remain usable after the pack moves into an image. The build still rejects any wrapper that retains its temporary deployment path. Ordinary remote Cursor startup uses the packaged Linux daemon and verifies every image asset against that manifest. A mismatched image fails before the provider starts; install the matching package and image together.

Native binary platform baseline

Release packages contain Paperclip daemons for linux-x64, linux-arm64, darwin-arm64, and darwin-x64. Codex native binaries are installed separately through the official optional npm platform dependencies described above.

The shipped Linux daemons target GNU libc 2.39 or newer, on x86-64 or AArch64. Their ELF version requirements include GLIBC_2.39; both depend on libc.so.6, libm.so.6, libgcc_s.so.1, and the matching GNU dynamic loader. The ARM64 loader is /lib/ld-linux-aarch64.so.1; x64 uses /lib64/ld-linux-x86-64.so.2. This is a binary compatibility baseline, not a promise that every Linux distribution or kernel has been qualified.

Hosted native producers use Ubuntu 24.04 for both Linux architectures. Clean npm install checks use the pinned Debian 13 Node image; the cloud Dockerfile uses Debian 13 (node:24-trixie-slim). macOS binaries build on the existing macOS 15 Apple Silicon and Intel hosts. Actual task and follow-up acceptance is performed on Apple Silicon; Intel qualification covers build, installation, and protocol startup.

For sandbox environments, the existing explicit environment probe can measure OS, architecture and libc from its allocated lease. It records those facts only for an image pinned with @sha256, after confirmed lease cleanup. The record is server-owned and bound to the company, effective provider/image configuration and active custom-image identity. Creation and discovery read this record without allocating a sandbox. Configuration or image changes invalidate it. Mutable tags, provider defaults and unverified snapshot names do not establish compatibility; they keep automatic Legacy selection until there is verifiable immutable image or Daytona snapshot-ID evidence. See managed snapshot qualification below. A connection-only success does not establish native readiness.

Managed Daytona snapshot qualification

Claude's automatic Connect flow can qualify a named Daytona snapshot through the existing administrator-only saved environment probe. The bundled Daytona plugin resolves the name to its provider snapshot ID, creates the probe sandbox by ID, and returns its account and creation identity. OS, architecture and libc facts are recorded only after confirmed cleanup. Native execution uses that same snapshot ID; discovery does not allocate or perform provider lookups. A deleted snapshot fails at the provider rather than silently selecting a replacement with the same name. Configuration, resolved credentials and active captured-template changes require another probe. Other named provider templates and mutable OCI tags remain unqualified. A provider plugin without snapshot identity support returns an actionable setup failure; it cannot certify a native default.

On Linux, Codex's sandboxed filesystem modes also require the host to permit its unprivileged namespaces. A no-privilege Docker container can prohibit nested namespace creation even when installation and binary compatibility pass. Qualification therefore retains the restricted Docker install/lifecycle checks and exercises the same installed graph's read-only native startup on the actual ARM host. This does not qualify arbitrary container or managed setup targets; their selected runtime must pass setup in that environment.

Ubuntu 24.04 also needs system bubblewrap and the stock bwrap-userns-restrict AppArmor profile described in Codex's Linux prerequisites. The qualified ARM64 host uses that distribution helper/profile while retaining AppArmor enforcement and global namespace restrictions. Hosted qualification materializes authenticated stock package files without running maintainer scripts; it verifies native startup and package continuity separately from the restricted Docker installation check. This does not prove a normal OS package installation journey or a paid provider task on ARM64.

Automatic creation selects legacy execution when a Linux host has musl, unknown libc, or a measured GNU libc version below the baseline. Existing agents retain their stored runner. Windows, 32-bit ARM, and Alpine/musl native qualification remain deferred. The Runner Windows workflow builds and tests the Rust workspace on Windows x64. It does not qualify Windows agent runs.

Native release jobs cache Cargo dependencies per platform and OS baseline, including compiler, lockfile, and external generated-contract inputs. Workspace crates and released binaries are rebuilt and verified every time. Only canonical exact-source master pushes may save trusted caches; preview qualification can restore them. JavaScript preparation and native compilation run concurrently, and both must succeed before artifact metadata and source-bound hashes are recorded. Run Docker and native qualification on hosted CI rather than a local developer machine.

Pi cold provider admission has an absolute 60-second budget. Warm run attachment checkpoints the old ACPX sidecar and starts a new one, so it uses that same budget while retaining the existing Runner authority. Live adoption and ordinary commands retain their 30-second bounds. Closing the transport cancels admission; an acknowledgement received after the admission deadline cannot revive it.

The board's transcript parser coalesces consecutive identical Pi runtime-failure display rows within one run, turn and session, including the exit handler and its late prompt rejection. Both original PRP facts remain in the run log. Distinct failure details, intervening retry activity and later turns remain visible. The profile-14 notice projection, wrapper bytes and terminal settlement remain unchanged.

Cursor candidate configuration accepts acpxSessionMode: "agent" | "plan" | "ask" (default agent). This selects the native Cursor mode independently of acpxPermissionMode and Paperclip task planning or company approvals. The mode is validated at the API boundary and is bound to provider admission and recovery; changing it cannot reuse an incompatible warm session. Other providers reject this setting. Cursor configuration requires an explicit model. Pending providers retain operator-controlled qualification admission.

Remote Codex sessions relay assigned app tools through the server's configured gateway. Small catalogs are sent directly. When a catalog would exceed the runner's 256-operation or 768 KiB contract limit, the server exposes paperclip_search_assigned_tools and paperclip_call_assigned_tool instead. Search accepts a limit from 1 to 20 and defaults to 5 results per page. Use the returned nextOffset as offset to read the next page. The tool and parameter descriptions include these bounds for providers that render numeric schema constraints as plain number types. Search returns bounded pages of names, descriptions, and input schemas. Each page intersects the session's pinned assignments with current gateway grants. An individual schema that exceeds a page returns an inputSchemaRef. The same search tool retrieves that schema in chunks via schemaTool and schemaOffset; discovery can continue past the large tool. Calls retain task ownership, work-mode restrictions, gateway authorization, approvals, and audit. Core task tools and the runner's completion tools keep their reserved space; no assigned tools are silently removed to fit the limit.

Native Claude skill assignments travel in the runtime-context snapshot through runnerd to the ACPX sidecar. After acquiring the provider lifetime lease, the host materializes the assigned bundles under the isolated Claude home's skills/ directory before launch. Reopening a provider refreshes that snapshot; project and ambient host settings remain excluded. This path is separate from the legacy claude_local adapter's remote skill staging.

The isolated Claude settings pin both model and availableModels to the user's requested ID. This keeps ACP from replacing an exact ID with a picker alias during selection and verification. Users can keep selecting models from the normal Claude catalog or entering custom IDs; unavailable models still fail at the provider rather than silently falling back.

ACPX Claude defaults to approve-all, shown as Full auto (approve all). OpenCode defaults to allow; native Codex defaults to never (no approval pauses). These defaults cover all assigned tools and connections, including provider-native operations. Full auto is resolved consistently for agent creation, adapter conversion, direct driver launches, and fresh/resumed turns. Explicitly stored restrictive modes still apply.

Native OpenCode forwards incremental text and reasoning parts as they arrive; the final full snapshot selects the final response without repeating streamed text. Delta parts must match an observed message and part identity. Identical chunks without event IDs remain distinct tokens. Each isolated launch disables automatic updates, remote model-catalog refreshes, and default plugins; the runner supplies the pinned executable, selected model, and assigned MCP tools. Provider inference and reasoning still contribute to time to first text. These startup settings do not disable model reasoning.

On macOS, the verified OpenCode executable keeps its private launch pathname until the provider process exits. Removing that pathname immediately after spawn can kill or stall the signed binary before its health check succeeds. Ownership, permissions, and file-identity checks remain enforced; cleanup also runs on failed launches, and retries create a fresh launch snapshot.

Call session.startTurn({ message, reasoningMode: "disabled" }) to disable reasoning for one OpenCode/OpenRouter turn. CapabilityLiveSession.sendMessage accepts the same option in its second argument. The choice travels in the durable turn.start command and selects an OpenCode model variant for that prompt only. Omitting it (or passing "default") on the next turn restores provider defaults, including on a warm or recovered session. It is not an environment variable or agent-wide setting. No automatic decision policy selects it. The model must support disabling reasoning; other runner providers reject an explicit selection before starting work. Native sessions expose support through the perTurnReasoning capability.

For the native openrouter/ route, the parent-held provider proxy retains the upstream OpenRouter key. The child config keeps the selected openrouter provider and exact model, using a random loopback token restricted to that model's chat completions endpoint. The proxy and token expire when the session closes. The local token remains a credential and is redacted from diagnostics; this does not claim isolation for every child credential or persisted value.

OpenCode's proxy sends agent instructions once per turn through the system prompt. The task envelope retains task-specific constraints and the completion contract, without repeating the system instructions. This applies to all users of the proxy; already-recorded conversation history is not rewritten.

The runner's authenticated bridge and controller still enforce company access, action claims, task modes, and governed approvals. Provider permission defaults do not change workspace isolation or grant credentials or connection access. approve-paperclip remains an optional narrower mode for assigned planning and task tools; approve-reads allows assigned reads; deny-all rejects requests. None of these restrictive modes is the default.

prepare_repository requires a provider permission decision in restrictive modes, including approve-paperclip: repository acquisition can clone onto the controller and is not automatically approved as a planning action. Full auto still allows it; repository acquisition currently has no cumulative disk quota.

Restrictive profiles route supported permission decisions through durable runtime requests and the existing task interaction controls. Requests are persisted before presentation; answers are checked against the offered decisions and acknowledged by the sidecar before settlement. Unknown, stale and duplicate responses fail. Missing provider decision support remains a blocked disposition, not implicit approval. Company access checks still run for each Paperclip tool. Provider death expires pending promises; approvals are never replayed into a replacement process.

Automatic Paperclip/read allowances currently require the Claude SDK dispatch boundary. Grok preserves these restricted settings, but its ACP requests lack independently bound tool authority. Those operations require a supported operator permission decision; a missing interactive responder stops with approval_required. An explicitly selected approve-all policy permits unattended Grok work in an assigned sandbox. Paperclip authorization and governed approvals still apply.

Runnerd selects only qualified provider profiles. Claude Managed and AWS AgentCore receive immutable company-profile snapshots with explicit retention, spend, and invocation limits. No provider process receives a Paperclip API credential or unrestricted server environment.

Claude Managed resolves its API key from the company secret bound to the selected profile. AWS AgentCore uses workload identity only; long-lived static AWS access keys are intentionally removed from the runner environment.

The Rust core includes a bounded client for the sidecar protocol. It enforces request identity, event order, frame and queue limits, timeouts, redacted diagnostics, and process-group cleanup. Runnerd selects this package-local transport only through an exact qualified provider descriptor.

Before a later provider adapter consumes a valid sidecar event, the Rust core also requires its optional or mandatory run and turn scope to match the active execution. Process and diagnostic events can remain global. All operational, tool, input, permission, and terminal events require the exact active binding.

A package-local payload boundary decodes events only after that scope check. It validates control identities, terminal status, question sets, and the admitted runtime event types and bounded fields. It redacts diagnostic and retained event values again before they can enter provider state. Authoritative semantic tool arguments are validated for transport bounds and forwarded unchanged, including credential-bearing document and instruction content. The provider harness owns credential policy; redaction of logs and audit previews must not reject or rewrite execution arguments. Diagnostic detection requires explicit credential fields/assignments or recognizable key, Bearer, JWT, or PEM formats, not ordinary prose such as "credential handling" or dotted filenames.

Human question tools accept one complete payload.questionSet for text and choice questions. The control plane generates legacy questions entries with stable free-text option IDs. Legacy callers remain supported. Calls that supply both forms must describe the same complete form; partial forms remain invalid. The native recovery bridge uses the same projection for answer delivery.

The server validates canonical answer constraints before persistence. Regex matching runs in isolated workers with a one-second deadline and at most four active workers. A timeout or capacity error leaves the question pending. The ordinary and native answer paths both await this validation before persistence. Saved native answer delivery does not repeat regex matching.

Validated ACPX runtime events normalize into the same provider-neutral activity families as the direct Codex transport. Reasoning contents stay private. Tool targets are resolved within the workspace under the provider host's path semantics and receive a versioned sidecar boundary marker before becoming bounded, display-only PRP safe paths. Raw or unmarked provider locations fail closed. URI-scheme and Windows drive-shaped values require a separate sidecar attestation backed by an existing in-workspace entry or, for a not-yet-created edit target, an existing in-workspace parent. This preserves real POSIX colon filenames without treating arbitrary URI text as a path. Windows separators are canonicalized, and consumers must not reinterpret the display value as file-access authority. Operational semantic-result and terminal events remain reserved for the stateful adapter rather than being duplicated.

The ACPX provider reducer preserves that order while it tracks one active turn, bounded assistant text, semantic results, and pending tool or input correlations. Terminal events flush the final assistant message first and clear unresolved turn-scoped requests.

The package-local session bootstrap starts the bounded sidecar transport, verifies the qualified capability handshake and effective model, opens one identity-bound session, and confirms its run attachment. Any failed bootstrap terminates the process; session shutdown preserves persistent provider state. The session can then start one immutable-workspace turn, request interruption, and reduce polled events through the scope-first state boundary. A mismatched command acknowledgement or invalid event terminates the session fail closed. Polled semantic calls pass through the run-scoped authorized tool bridge before they can be returned to a caller. Before a follow-up turn releases settled tool receipts, runner-core suspends and reaps the idle sidecar/provider generation, then resumes the same verified persistent identity in a fresh generation. This prevents a late session-lifetime MCP callback from inheriting the next turn's event authority.

The Rust question-response validator checks the versioned response envelope against the exact persisted question IDs, answer modes, options, required answers, custom-answer policy, and text constraints before provider delivery. Tool results and structured question responses then use two-phase resolution: validate retained identity and schema, require the exact sidecar acknowledgement, and only then clear pending local state. Codex permission requests violate its pinned sidecar policy and terminate the session fail closed. Safe suspension is available only with no active turn or pending request. The sidecar must return the exact persistent session identity before runnerd terminates the local process. Already validated ACPX reducer events project into provider-neutral durable events only with an exact run, session, turn, and item binding. Raw sidecar envelopes and permission requests are not admitted at this boundary. A safely suspended session can be recorded as a bounded private checkpoint. The checkpoint binds the exact provider identity, run, catalog revision, and catalog digest and is replaced atomically before a later recovery attempt. Recovery releases the stored identity only after those bindings match the prospective session configuration exactly.

Run the complete contract gate with:

pnpm install --filter @paperclipai/paperclip-runner --lockfile=false --offline --ignore-scripts --dev
pnpm --filter @paperclipai/paperclip-runner verify

The verification command requires a stable Rust toolchain with cargo on PATH, in addition to Node.js 24.11+ and pnpm 9+.

Rust development builds use debug = "line-tables-only" to reduce build storage while retaining file names and line numbers in backtraces. The default test profile inherits this setting. Incremental compilation remains enabled, and release profiles keep their existing settings. For full debugger support, including local variables and types, set CARGO_PROFILE_DEV_DEBUG=2 and CARGO_PROFILE_TEST_DEBUG=2 for the build or test command.

Minimal Debian/Ubuntu hosts without root access can extract the required Playwright browser libraries into a user-owned cache and run the same acceptance sequence with:

pnpm --filter @paperclipai/paperclip-runner verify:rootless

The tracer's final line is stable:

{
  "schemaVersion": "paperclip.runner.conformance.output.v1",
  "runIdentity": {
    "runId": "run_conformance_0001",
    "sessionId": "session_conformance_0001"
  },
  "result": {
    "status": "succeeded",
    "summary": "Standalone Conformance fixture accepted."
  }
}

Run only the tracer with:

pnpm --filter @paperclipai/paperclip-runner trace:conformance

Replay the Replay happy path, run a Local session, or open the browser devtool:

pnpm --filter @paperclipai/paperclip-runner demo:standalone

Live console provider-backed routes are loopback-only and reject wildcard/LAN binds. Browser mutations require same-origin Fetch Metadata, matching Origin, and JSON content; see the protocol-server tutorial for direct curl examples.

The runtime activity publisher has an offline final-command regression against the qualified Codex executable. Run it on a host that supports Codex's OS sandbox, with the pinned executable and the matching freshly built Runner helper:

CODEX_NOTIFICATION_SANDBOX_COMMAND=/absolute/path/to/pinned/codex \
PAPERCLIP_RUNTIME_NOTIFICATION_HELPER=/absolute/path/to/paperclip-runnerd \
cargo test --release --manifest-path runner/Cargo.toml --locked -p paperclip-runner-core --lib \
  publisher_crosses_real_codex_tool_boundary_without_runner_state_access -- --ignored

This uses app-server command/exec without credentials or a model call. It checks actual shell discovery, successful durable activity recording, and denial of unrelated Runner state, descriptor writes and ambient secrets. The normal suite covers bounded framing, concurrent publishers, fixed-path cleanup and attachment fencing.

Direct live protocol qualification

The canonical direct live protocol suite lives in the separate paperclip-evals repository under evals/paperclip-runner/. Its live-mini.json roster is the complete 35-case Codex qualification lane. Build this package's TypeScript output, release paperclip-runnerd, package tarball, and dist-issue-thread viewer, then use the roster runner documented in that repository. The package ships the required orchestration entry point as paperclip-runner-eval-session (dist/cli/eval-session.js). Evalbook owns the consistent HTML matrix and read-only attempt drill-down pages.

The hosted full-campaign workflow, parallel matrix, credential boundaries, canonical report merge, and versioned S3 index are documented in docs/runner-protocol-live-evals.md.

This direct protocol qualification is separate from the stress-derived Runner workflow schedule below and from the full-stack browser model E2E suite.

Stress-derived workflow, chaos, and AWS AgentCore operations

The deterministic workflow scorer and the chaos schedule do not require provider credentials:

pnpm --filter @paperclipai/paperclip-runner test:runner-workflow-evals
pnpm --filter @paperclipai/paperclip-runner report:runner-chaos-evals

report:runner-live-evals is a paid, provider-backed command. Native Codex requires OPENAI_API_KEY; ACPX Claude requires ANTHROPIC_API_KEY; OpenCode candidates require OPENROUTER_API_KEY. The live matrix remains qualified-only and does not persist credential values. Candidate qualification uses eval-session --candidate-profile <pi|cursor|copilot> with an explicit model and a separately materialized pinned candidate pack. This option is a constructor-bound diagnostic opt-in; session JSON cannot enable a candidate. Missing credentials or unverifiable spend block paid qualification. Set PAPERCLIP_EVAL_MAX_CAMPAIGN_COST_USD to a positive finite number to bound additional scheduling after the observed campaign total reaches that value:

PAPERCLIP_EVAL_MAX_CAMPAIGN_COST_USD=12 \
  PAPERCLIP_EVALS_ROOT=/path/to/paperclip-evals \
  pnpm --filter @paperclipai/paperclip-runner report:runner-live-evals

# Run two scheduled native Codex executions only.
PAPERCLIP_EVALS_ROOT=/path/to/paperclip-evals \
  pnpm --filter @paperclipai/paperclip-runner report:runner-live-evals -- \
  --candidate codex-luna --limit 2

GitHub-hosted live campaigns additionally require the default branch, an allowlisted numeric actor ID, the protected runner-e2e-paid environment, and an explicit repository variable before scheduled runs are enabled. Manual dispatches accept the same candidate, case, and execution-limit selectors. The paid job uses the reviewed RunsOn Fleet label when RUNNER_E2E_AWS_ENABLED=true and otherwise stays on ubuntu-latest. Uploaded reports contain redacted observations and trace digests, not raw provider frames, prompts, credentials, tool arguments, or hidden reasoning.

The AgentCore proof-of-concept uses an AWS CLI v2 profile to provision a dedicated invocation role and scoped resources. Its local mode-0600 metadata file contains no access keys; probes assume short-lived STS credentials and clear them after use. Validate locally, provision or inspect the stack, run the bounded lab/smoke, and tear it down explicitly with:

pnpm --filter @paperclipai/paperclip-runner test:aws-agentcore-provisioning
pnpm --filter @paperclipai/paperclip-runner aws-agentcore:provision -- --dry-run
pnpm --filter @paperclipai/paperclip-runner aws-agentcore:provision
pnpm --filter @paperclipai/paperclip-runner aws-agentcore:probe
pnpm --filter @paperclipai/paperclip-runner aws-agentcore:lab
pnpm --filter @paperclipai/paperclip-runner smoke:capability:aws-agentcore
pnpm --filter @paperclipai/paperclip-runner aws-agentcore:destroy -- --yes

To admit the hosted direct-eval workflow, provision with the account-local GitHub Actions OIDC provider and keep the default exact repository and protected environment binding:

pnpm --filter @paperclipai/paperclip-runner aws-agentcore:provision -- \
  --aws-profile paperclip-dev \
  --github-oidc-provider-arn arn:aws:iam::<account-id>:oidc-provider/token.actions.githubusercontent.com

This adds only repo:paperclipai/paperclip:environment:runner-e2e-paid as a web-identity subject on the scoped invocation role. The generated nonsecret profile records that role as both the local invocation role and the hosted execution role.

Provisioning can incur Bedrock, AgentCore Runtime/Memory, storage, and private networking charges. Provisioning refuses to modify a colliding stack unless its Paperclip ownership tags and template description match. A verified ROLLBACK_COMPLETE stack still requires --replace-failed-stack plus an interactive confirmation (or --yes) before it can be deleted and recreated. Destruction requires --yes and refuses to remove a stack with an active recorded lab unless --force is also supplied.

Navigate

Codex adds the package-local real-model reference driver, Live console adds the package-local browser console, and SDK extracts a reusable public SDK plus two standalone consumers. Runtime production Paperclip integration remains deferred; the App-owned production conformance adapter is test-only.

The SDK reference console opens in direct chat mode. Enter a normal prompt, then open the protocol inspector to review events and reducer state. Expand a Terminal row and its nested Debug details disclosure to inspect every canonical event retained for that command. The header marker 🖇️ v0.1.2 identifies the current console iteration.

create_task accepts an optional initial status of backlog or todo. Use backlog when the user wants a saved task or plan without execution: assignment and the initial plan are committed without scheduling a wake, even when dependencies are already complete. Omitting status preserves immediate delegation (todo, or blocked for unresolved dependencies).

Linux provider-pack producers run on the corresponding native Linux target and retain provider-pack.json with a relocatable provider-pack.tar.gz. Release assembly binds both identities to the same source as its four daemons. The historical remoteProviderPack field remains the Linux x64 identity. Linux ARM64 packs do not qualify Pi, Cursor or Copilot on that target.

For an installed SSH host, install the same release producer's pack at $HOME/.local/share/paperclip-runner/provider-pack or /opt/paperclip-runner/provider-pack. A Mac controller selects its packaged Linux target identity after probing the selected host. The runtime verifies the installed pack before prompting. No development pack override is needed. A missing or mismatched pack fails clearly. Existing explicit overrides remain authoritative. ARM64 cloud-image production remains deferred.

Oversized OpenCode events

The OpenCode driver keeps SSE frames up to 1,048,576 characters exact. It compacts longer frames while retaining tool identity, status, and bounded output excerpts. This also applies when a complete large frame arrives inside one network chunk. Canonical tool rows mark shortened output, report its original byte count, and do not claim a digest for text that was not retained. A structure that cannot fit the compacted bound produces a diagnostic; the event stream continues.

Tool output and error fields have reserved retention space and size records, so large input values cannot consume their output tails or make excerpts look complete. A separator split between reads does not count against the frame limit.

OpenCode MCP tool results

The Runner-owned MCP bridge sends complete JSON tool results up to 1 MiB of UTF-8 output. It does not slice JSON text. This includes the native server's bounded 500 KB app-tool results and saved-result pages. OpenCode can put a long result in its own output file; that file must still contain the complete JSON. The existing read_tool_result artifact protocol handles larger app results.

Serialization has a bounded traversal budget and checks escaped UTF-8 output. If delivery exceeds the limit, the bridge reports an error without a partial success value. The action may already have completed. Reconcile its saved result or receipt instead of repeating it. Replaying the same MCP call identity reuses the original handler execution, including when delivery failed.

Prepared harness storage

An execution environment can supply an existing Claude configuration directory through PAPERCLIP_RUNNER_PREPARED_HARNESS_HOME, using an absolute, non-symlinked path. Runner derives CLAUDE_CONFIG_DIR from this value, overriding any separately supplied value. This selects persistent harness storage without changing the run's permission mode or enabling preconfigured-home behavior. HOME remains the execution account's home. Each account must use its own configuration directory. The environment must publish the selected skills before admission; Runner does not copy or delete skills in this directory. On Unix, the directory must belong to the Runner user and use mode 0700; the provider lifetime lease rejects group/world access or another owner.

Runner binds the home into recovery identity and uses its existing provider lifetime lease. After acquiring that lease, it replaces Core-owned Claude settings with the current launch settings. History remains in the account directory. Task control files remain in the session runtime directory. Separate directories under one OS user are not a credential isolation boundary.

Preconfigured home

Set homeMode: "preconfigured" in a paperclip_runner agent's adapter config (or the runnerd transport options) to use the execution account's existing home. The default is "isolated". The initial supported providers are native Codex and ACPX Claude. Preconfigured ACPX Codex fails before launch until its session permissions can enforce denial of Runner state; use native Codex or isolated mode. An operator must select this mode on the agent/Runner configuration. Task-level overrides are rejected, and agent credentials cannot set or inherit this option. Other providers reject this option. The internal ACPX task bridge uses a stable session name so an existing user MCP server named paperclip remains available.

Prepare authentication, skills, and external MCP servers on the execution machine before launching. Runner does not install skills, copy or remove credentials, or rewrite user configuration in this mode. Providers can still refresh credentials and update their own metadata. Runner still supplies the requested model, task instructions, and its internal task/completion tools. Claude session loads and resumes receive the same native session options as session creation, including allowed tools and the selected settings sources. Local permission rules and hooks apply. Native Codex tools can read and modify the execution home (read-only for planning); credentials in that home are not isolated from tools. Native Codex separately denies Runner-owned protocol state; ACPX Claude retains its existing provider trust boundary. Execution is unattended: native Codex uses never, and ACPX rejects requests for approval. When Claude starts in its home directory, its native user settings retain user trust even if the SDK also reports that same file as project settings. Other project settings keep the native trust filter. The initial ACPX mode requires the Runner setting acpxPermissionMode: "approve-all" (its default); other Runner modes are unqualified here and fail before launch. Local permission rules still apply. Preconfigured ACPX read-only/planning tasks also fail before provider launch until a read-only launch is qualified; use isolated mode or native Codex for planning. If local settings block a task, change them and retry. Existing blocked results and failure diagnostics report the outcome; a hook that also blocks the reporting tool can leave only a generic diagnostic.

Runner retains private protocol/session state and a fence for each session. Different sessions may share the same home. Mode and home bindings fence recovery; switching either requires a new session. Backups never include the external home. Recovering a run uses its saved mode even if the agent configuration has changed. Remote execution discovers the execution account's home on the remote machine using getent; it does not copy the controller's HOME, XDG paths, or login state. The external provider history must still exist to resume a session after a remote machine is replaced. Missing history fails recovery rather than importing an isolated home. OpenCode and the remaining ACPX profiles require separate qualification before this mode can be enabled for them.

Assigned local MCP servers

An execution host can assign local stdio MCP servers alongside the existing PAPERCLIP_NATIVE_MCP_NAME / URL / TOKEN HTTP gateway. This is general transport support for local MCP implementations that satisfy the executable-verification and private Unix socket requirements below. Runner uses each server's own tool schemas and responses. Set PAPERCLIP_NATIVE_MCP_STDIO to a JSON array of bindings with these fields:

[{"name":"local_tools","command":"/opt/local-tools/bin/mcp-server","args":[],"env":{"HOME":"/home/agent"},"sha256":"sha256:<64 lowercase hex digits>","serialResource":"/home/agent/.local/state/local-tools/runtime/service.sock"}]

serialResource identifies the shared resource for cross-process call locking; the MCP transport itself uses stdio. It must name an existing private Unix socket with the ownership and path requirements below.

Set PAPERCLIP_NATIVE_MCP_PROXY to the assigned Runner executable. These are execution-host inputs, excluded from configurable task environment and provider shell inheritance. Names use letters, digits, underscores or hyphens and cannot replace the internal task server or gateway. Commands are verified against their assigned digest before execution. The backend receives only its assigned environment.

Runner supplies these session-local bindings to native Codex and through the shared ACPX runtime. ACPX clients must support stdio MCP assignments. User or project MCP files are never rewritten. Read-only sessions omit these bindings. Host assignment authorizes native Codex to use these local tools without a new per-call prompt, matching execution-host utilities available through shell. ACPX adapters use the existing ACPX permission policy. Explicit native Codex tool deny/prompt rules remain effective; requested approvals use the existing PRP permission request, bound to the active thread and turn. Only one-time accept, decline or cancel decisions are accepted. Shell escalation stays disabled. Preconfigured Claude remains unattended and rejects approval requests.

The relay forwards tool schemas and native MCP content. For native Codex 0.160/0.162, image-bearing results put structured metadata in a text block instead of structuredContent, because those clients otherwise discard the image blocks. ACPX adapters receive the original response unchanged. Tool schemas and actions are forwarded without provider-specific translation.

Provider-client smoke tests exercised native Codex 0.160.0 and Claude SDK 0.3.286 with local MCP servers and loopback model APIs. This records the clients used to verify image delivery and approvals; it is not an exhaustive adapter compatibility test.

All tools/call requests for the same private Unix socket are serialized across sessions and processes, including reads. Metadata requests stay responsive. Cancelling a queued request prevents dispatch. An active request retains its fence until the backend acknowledges it; client cancellation cannot prove daemon work stopped. If a relay exits with an unacknowledged call, later calls fail closed until the host restarts that resource with a new socket. Do not remove its lock marker while daemon work might still be running. The socket and its parent must be private, canonical paths owned by the same account. Local stdio assignment requires Unix; other platforms retain the HTTP path.

Kimi Code

Kimi Code uses the pinned @moonshot-ai/kimi-code@2.3.3 distribution through ACPX through the qualified native profile. Ordinary selection and Runtime Test require no candidate grant. The installation targets are macOS ARM64 and Linux x64. Platform startup, authenticated driver checks, and product acceptance are separate evidence levels.

Run paperclipai runtime setup kimi on the execution host to install its complete verified runtime. Setup downloads public pinned dependencies without model calls or provider credentials. An invalid existing installation fails without ambient Kimi fallback. Bind a company secret as KIMI_API_KEY and select an exact model. This release uses the global Code endpoint at https://api.kimi.ai/coding/v1. Model suggestions are empty; a compatible typed model is decided by the provider. The account needs Kimi Code entitlement. Runtime Test verifies installation and queries the authenticated Code model catalog for the exact selected model. It sends no model prompt; an actual task verifies inference and tool execution.

The qualified native profile uses ordinary setup, hiring, metadata Test and task startup on these two supported targets without operator admission flags. Protected candidate startup records remain reserved for future pending profiles; saved agent configuration and public requests cannot supply that authority.

Existing legacy Kimi agents retain their runtime and history. Managed Kimi connections, ambient login borrowing, other regions/platforms, steering, native child work, and per-run token/dollar accounting are outside this release. Read-only Kimi work uses scoped Paperclip tools; native filesystem and shell tools are denied. The provider-owned patch binds native instructions, preserves permission arguments, and removes provider auth from tool subprocesses. See the protocol dossier and release ledger for current evidence and limits.

ACPX controller replacement regression tests

src/control-plane/acpx-controller-recovery.test.ts runs the production Rust Runner and authenticated PRP controller with a scripted ACPX peer. It covers active-turn reconnection, checkpoint restoration after deleting controller storage, native transport adoption and old-controller finalization, completion while disconnected, a provider crash, and an explicitly closed provider. It builds the debug Runner before execution and requires Cargo and a POSIX host. No model credentials, provider requests, application server or database are used.

pnpm --filter @paperclipai/paperclip-runner exec vitest run \
  src/control-plane/acpx-controller-recovery.test.ts --maxWorkers=1

Set PAPERCLIP_ACPX_REPRO_BINARY to an existing Runner executable to skip the Cargo build. All five tests still run. Set PAPERCLIP_ACPX_REPRO_PROFILES to an alternate acpx-profiles.json when that executable uses a different profile manifest. Both overrides are optional.

The failure controls distinguish a lost provider from a controller outage; matching a diagnostic after explicit close does not identify the cause of a hosted failure. Real Claude/ACPX acceptance, server/Postgres recovery, and Daytona deployment continuity need their own evidence. See the remote continuity guide and the Daytona Product E2E suite.
