DottaandPaperclip 45a3a92e6d fix(environments): persist sandbox ownership before creation (#18357)
## Thinking Path

> - Paperclip manages companies and the agents that do their work.
> - Remote execution creates provider resources that need a durable
owner.
> - The server could create a sandbox before it saved its lease.
> - A failed lease write could leave cleanup data only on the old web
server disk.
> - This change saves a company-scoped operation before creation and
transfers ownership atomically.
> - Recovery finds the original Daytona resource or records an explicit
manual reconciliation outcome.

## Linked Issues or Issue Description

**What happened?**
A sandbox could exist without a lease after a database failure or
company rebind. Failed cleanup recording could then create a local
fallback file. Replacing that web server could lose the cleanup
reference.

**Expected behavior**
A failed admission write makes no provider call. An interrupted creation
retains a committed operation. Recovery must not create a second sandbox
or destroy an attached lease.

**Steps to reproduce**
1. Run the disposable PostgreSQL cases in
`server/src/__tests__/sandbox-creation-operations.test.ts`.
2. Reject the lease insert after the controlled provider creates its
resource.
3. Start a new receiver process with a different empty web disk. It must
find the same resource and create one cleanup owner.

Related ownership report: Refs #14672. This change addresses new
allocations before lease persistence. It does not replace existing lease
recovery.

## What Changed

- Add an idempotent migration and a small creation-operation table.
Retain original company, environment and run identities across deletion.
- Commit creation intent before run, ad-hoc lease, and plugin task
replacement calls. Fence duplicate requests and ambiguous lease commits.
- Retain a known returned task resource ID in the existing operation
before attachment. Preserve manual reconciliation and never delete an
ambiguously attached resource.
- Keep company and run authority checks and atomic lease transfer with
the lease owner.
- Reuse Daytona names, labels, read-only inspection and claimed cleanup.
Keep provider payload handling in the provider.
- Retain nonsecret credential identity hashes. Refuse recovery lookup
under a changed credential value.
- Record manual reconciliation for missing/deleted or explicitly
inactive saved credentials, versions, and provider vaults. Keep
temporary resolution failures retryable. Never reactivate a disabled
credential.
- Use transaction signals and concrete deadlines. Failed records back
off independently. Manual reconciliation stays durable and quiet.
- Remove new orphan-file fallback writes from the covered paths. Keep
legacy file replay and its tests for cutover.
- Replace obsolete fallback-producer assertions with normal-entrypoint
durability tests. Keep cleanup, diagnostics and warm handoff coverage.

## Verification

- [Independent current-head
verification](https://github.com/paperclipai/paperclip/pull/18357#issuecomment-6534744320)
passed 190/190 combined tests, 40/40 incoming TestOps tests, full
workspace typecheck, and build. PR head
`958af986130f25e136065ad30d1fdd843c46255c` has tree
`e6c3e5b02182d5941a70ccf5bf55638df3c2e28d`, identical to tested combined
commit `b9d7a9c2e9b30f0153685fb24a5f70b56132201f`. Real PostgreSQL,
compiled Rust Runner and controlled object providers were used;
external-S3 integration remains outside this local proof.
- Current head `958af986130f25e136065ad30d1fdd843c46255c` normally
merges master `8595efc20bda3ce20a9fbbf34a5d156a6fcf6d57`. The sole
conflict was the maintenance test: a parameterized case now preserves
both legacy-local `local_storage` and valid shared-S3
`provider_mismatch` checks, including the parent local receipt, exact
version identity, missing-snapshot/no-seed refusal, and unchanged
persisted row. The three master TestOps files remain intact. No
production, schema, migration, or package changes were made after the
fully qualified prior head `0b4d05505e`. Independent review approved the
resolution; the full managed-skill-content file and Cloud guard controls
pass 58/58 (105.11 seconds). [Required PR CI passed on this exact merge
head, first
attempt](https://github.com/paperclipai/paperclip/actions/runs/41136987412):
54 successful checks and three intended skips. The additional Paperclip
review is neutral at 4/5; two external Superagent checks (Contributor
trust and Security Scan) remain in progress with zero annotations and no
assessment, so they are not passing scan evidence. Greptile reviewed
exact head `958af986130f25e136065ad30d1fdd843c46255c` at 5/5; the final
thread audit has zero unresolved threads. All completed evidence below
retains its recorded revision scope. The additional Paperclip Review on
`958af98613` is neutral at 4/5 with a Ship verdict and no must-fix or
should-fix item. Its optional observation is that a generic create
rejection remains pending/manual even when an operator believes
allocation did not occur. This change preserves uncertainty because the
generic create-error contract does not prove provider absence; no new
error classification or provider-specific compensation was added.

- [Independent final-source
verification](https://github.com/paperclipai/paperclip/pull/18357#issuecomment-6534328247)
passed all 189 real-PostgreSQL/Runner and controlled-fixture cases, full
workspace typecheck, and build. The integration commit
`c8411a8528386f4824b340ec5fdaaed1efb9ea69` has the same source tree as
final PR head `0b4d05505e` (tree
`bda65efc14b4c904d0f589154db77bb160641c8c`). Controlled object-provider
coverage passed; the separately guarded external-S3 suite was not run
because the bounded local MinIO pull was unavailable. This includes the
two final compatibility fixes.
- The first final-head CI attempt exposed one E2E timing failure in
`disconnect-write-recovery.spec.ts:181`: the title stayed unchanged
through the 15-second session-recovery poll. The same original case
passed in 13.8 seconds on immediately prior head `7ec06f77b7`, and all
UI/session/E2E source is identical across those heads. The failure log
and CI artifacts are retained; no cause is claimed. One failed-job-only
retry is authorized on this evidence, without changing a timeout,
assertion, or production behavior. [The single failed-job retry
completed
successfully](https://github.com/paperclipai/paperclip/actions/runs/41133619710/attempts/2):
all 35 E2E shard cases passed (6.6 minutes), including the original
session-recovery case in 14.0 seconds. The initial failure remains
disclosed and its cause remains unproven.
- Final head `0b4d05505ee0aa72f2981cdff74761406960ec73` adds two
independently reviewed integration fixes after the complete 7ec CI
matrix exposed two deterministic failures. Server 9/12 failed legacy
local-storage maintenance because the CLI reached the new Cloud server
startup guard; server 5/12 found the Daytona package version did not
match its bumped manifest. The failed run is retained at
https://github.com/paperclipai/paperclip/actions/runs/41131204203. It is
not passing evidence and was not blindly retried.
- Maintenance now constructs the existing explicit storage dependency
after loading the required persisted Cloud snapshot, and passes it to
both maintenance owners. It can verify legacy local storage before
provider cutover while normal Cloud server startup remains guarded. The
original case reproduced red locally, then the complete
managed-skill-content and managed-cloud-prerequisites files passed 57/57
(32.05 seconds), including missing-snapshot refusal, unchanged stored
configuration, and existing server guard controls. Daytona package
version now matches manifest 0.1.10; the complete bundled package
identity file passed 14/14 (3.98 seconds), and explicit
manifest/lifecycle controls passed 2/2 (328 intentionally filtered; 3.42
seconds). An initial workspace-filter command matched no project and is
not counted as pass evidence. The final diff changes no sandbox runtime
or schema behavior. [Full CI is green on this exact final
head](https://github.com/paperclipai/paperclip/actions/runs/41133619710/attempts/2):
56 successful checks, three intended skips, one additional
incomplete/neutral Paperclip Review, and no pending or failed checks.
The neutral review is not a passing assessment. [Greptile reviewed the
exact final head at
5/5](https://github.com/paperclipai/paperclip/pull/18357#issuecomment-6529396969),
with no new actionable issues and all review threads resolved.
- Final combined head `7ec06f77b7c14a745c569d18401f16df3d26b626`
includes master managed-skills migration 0417 and shared-storage
prerequisites from `198218bf55` through normal merges. Sandbox creation
moves to generated `0418_curved_lady_mastermind.sql`; its idempotent SQL
is byte-for-byte unchanged. The regenerated 0418 snapshot contains both
sandbox creation operations and the master skill mutation receipts, and
points to the master 0417 snapshot. Master SQL and journal history
remain intact. Exactly five snapshots remain, 0414 through 0418. The
only sandbox-specific changes since the approved credential policy are
migration metadata/number and the matching test/document references; the
sandbox runtime files are unchanged.
- [Independent final combined
verification](https://github.com/paperclipai/paperclip/pull/18357#issuecomment-6533960026)
passed on integration revision `e6f05b4cf0cd`, containing final sandbox
head `7ec06f77b7` and actual master `198218bf55`: migration/declaration
checks, all 158 real-PostgreSQL/Runner and controlled-fixture cases (251
seconds), full workspace typecheck (81 seconds), and build (35 seconds).
- Final combined migration proof: fresh real PostgreSQL has both tables.
A separate original-0417 sandbox table with a retained pending row
survives two applications of the renamed 0418 SQL unchanged, with the
expected primary/index and foreign-key structure. Migration
numbering/safety checks pass. The normal runtime migration reapply case
passes 1/1 (20 intentionally filtered cases; 46.69 seconds). The first
temporary qualification harness stopped before any database assertion
because its external `.ts` file selected CommonJS; the `.mts` harness
corrected that setup and passed. Independent review approved the exact
metadata and reference diff. Earlier full suite and live-provider
results below retain their stated revision scope.

- Credential-policy head `c606d473b03709f27577a55a1dfc0b0d3b4359fd`
handles the remaining inactive-credential review warning. The existing
boundary accepts only concrete secret-owner 422 codes and exact
no-details disabled/coming-soon vault messages. Unknown 422,
authorization errors, provider wrappers, and temporary database/provider
failures still propagate. Independent source review approved this
three-file correction. No generic resolver, schema, provider protocol,
retry cap, or activation behavior changed.
- Creation/cleanup qualification at `c606d473b0`: all 39 cases pass
against real PostgreSQL (81.27 seconds). The new cases use actual
disabled/archived saved secrets, a valid disabled version, and provider
vaults created ready before normal API updates disable them or mark them
coming soon. Each remains manual through restart/repeated scans, with
zero provider lookup and no retry deadline. The independent plugin idle
blocker remains intact. The temporary 503 control retains retry
ownership and later recovers one cleanup owner. Before this correction,
all five inactive-state cases remained pending; that failed evidence is
retained. The prior 18-case known-ID task proof below belongs to
`237144fcf6`, whose helper and task path are unchanged by this
correction.

- Known-ID head `237144fcf69a249c0e0310563428c0f55ed6d55c` also
addresses the independent task-replacement reliability warning. The
existing creation operation now saves only the known nonsecret returned
resource ID before expiry validation and attachment. The write is scoped
to operation/company/original environment and allows only a missing or
matching ID. It changes no ownership state and copies no resolved
configuration, credentials, or provider payload. Independent source
review approved this four-file fix.
- The complete real-PostgreSQL task suite passes 18/18 (9.52 seconds).
Rejected attachments retain the ID through manual reconciliation and
repeated scans. A real committed attachment followed by an injected lost
response retains the same active lease and attached operation, with no
release or second create. Same-ID retries work; conflicting IDs and
foreign companies cannot change it. The initial three regression cases
failed because the ID was absent, before the fix.
- The shipped Daytona manifest does not declare task support, so it
cannot enter this generic replacement path. The dispatcher requires both
declared task support and an environmentTask worker method. Generic
drivers without creation lookup still use manual reconciliation, with a
known returned ID retained when the database write can commit. No
automatic lookup capability or unconditional compensation was added.

- Previous boundary-fix head `8ba77def151ea85eeae2db7693254db7f87673b0`
fixes the fresh review finding about missing credentials. Only known
secret-owner 404 results at the recovery secret-resolution boundary
select the existing manual outcome. Provider inspection and transient
database/provider errors remain retryable. Independent source review
approved this change.
- Secret-boundary focused acceptance at `8ba77def15`: all 34 cases pass
against isolated real PostgreSQL. The complete creation suite passes
16/16 (100.75 seconds); the complete cleanup coordinator suite passes
18/18 (99.83 seconds). The new cases use normal saved-secret creation
and deletion, confirm zero provider lookup, restart/repeated scans, no
automatic deadline, preserved independent plugin idle blocking, and no
additional idle blocker after the controlled worker supplies its quiet
proof. A temporary 503 resolution failure preserves pending ownership
and later recovers one cleanup owner. No additional live provider
resource was created.
- Failed attempts remain part of the evidence. The initial red run
reproduced the pending-operation bug and also exposed a numeric-deadline
test harness mistake, which was corrected. A later combined run reported
an existing replacement-receiver failure and a new idle-fixture
assertion failure; it was interrupted while the next test file remained
in imports. An isolated diagnostic confirmed that the manual state was
correct but the installed fixture plugin correctly blocked sleep without
its independent quiet proof. The corrected test retains that blocker
assertion before supplying the controlled worker witness. The unchanged
replacement-receiver case passes in the final complete 16-case run; its
earlier failure is not counted as a pass or assigned a proven cause. No
timeout or production idle guard was relaxed.
- Greptile reviewed previous combined head
`7ec06f77b7c14a745c569d18401f16df3d26b626` at 5/5, with no unresolved
review threads. Its CI produced the two concrete integration failures
addressed above. The earlier CI and live evidence below remain
historical evidence, not a claim that the current full gates have
completed.

- Master integration update: merged `dbff3747b8` and then latest master
`76fde891cc` without rewriting branch history. Only `doc/DATABASE.md`
conflicted; the sandbox ownership, object-backed run evidence, and cloud
configuration sections all remain. The master merges changed no sandbox
implementation, migration, or provider code. Migration numbering/safety
checks pass and exactly five schema snapshots remain. At merge head
`f5d23d4a59828835d01c150f83fa2645fb2d3bec`, the two focused
creation/coordinator suites pass all 32 cases against isolated real
PostgreSQL (64.57 seconds). Those merge-head checks precede the
missing-credential fix below. The earlier live Daytona proof still
covers the unchanged normal creation/lookup/teardown path; the new
missing-credential branch is qualified with real PostgreSQL and
controlled provider hooks.

The optional Superagent Security Scan was inconclusive on prior head
`7ec06f77b7`: its pinned PR merge-base checkout failed or timed out,
with a neutral conclusion and zero annotations. An earlier scan could
not start within 120 seconds; a bounded rerun request returned HTTP 404.
These scanner failures are not passing security-scan evidence. On final
head `0b4d05505e`, the additional Paperclip Review check is neutral: its
assigned review execution did not complete and produced no validated
assessment. Fresh Greptile 5/5 and independent source review are
separate evidence. Previous-head required CI, independent review, and
the live Daytona qualification below passed.

- [Complete previous-head
CI](https://github.com/paperclipai/paperclip/actions/runs/41105726052)
passed at `0b5cbb763ab8faa25aa0ff1d8a405cdc0d3db409`: 53 successful
checks and three intended skips, including typecheck, full tests, build
and E2E. Greptile is 5/5 on this head and both original findings are
resolved.

- Initial head: 200 PostgreSQL runtime, creation and coordinator tests
passed. The corrected head also passes all 32 creation and coordinator
tests, including deletion before/during lookup, a failed lookup after
deletion, restart, settled polling and actual idle-safety checks. Cases
cover failed admission, failed lease writes, concurrent recovery, lost
provider replies, ambiguous transfer retries, company rebind,
environment deletion, stopped runs, lookup backoff, restart, drain and
settled SQL quiet.
- Separate receiver processes: passed. A controlled HTTP provider
retains the resource while three independent receiver processes use two
empty web disks. Recovery creates one cleanup owner and never repeats
creation.
- Fresh PostgreSQL migration and two additional applications: passed.
The pending creation row survives unchanged.
- Server TypeScript and SDK/shared build checks pass after the
corrections. Migration numbering/safety checks passed. Exactly five
schema snapshots remain.
- Daytona adapter: all 330 tests passed, including stable-name lookup,
ownership checks, deletion and the updated manifest version. An earlier
run exposed the version expectation and it was corrected. Previous-head
CI passed.
- Live Daytona acceptance passed on `0b5cbb763a`: isolated real
PostgreSQL, normal runtime acquisition through independent receiver
processes, actual Daytona plugin/SDK 0.203.0, one disposable Ubuntu
24.04 sandbox (1 CPU / 1 GiB RAM / 1 GiB disk). A forced lease insert
failure retained the committed operation; a fresh receiver with empty
disk found the same sandbox, repeated recovery retained one cleanup
owner, and the actual claimed cleanup sweep expired the lease and
resolved the operation. Independent SDK lookup returned typed not-found;
ordinary recorded-ID inspection returned destroyed. This successful
attempt made one create, one recovery lookup, and one teardown. Two
earlier failed harness/provider-confirmation attempts are disclosed in
the [live acceptance
record](https://github.com/paperclipai/paperclip/pull/18357#issuecomment-6530313054).
The coordinator independently queried all three exact resource IDs
through the SDK and confirmed typed not-found for each.
- Complete CI-affected heartbeat/plugin warm-task suites passed 21/21
after test corrections. An unchanged workspace exposure case passed in
isolation after the prior CI shard reported an unhandled readiness
rejection. Complete previous-head CI and refreshed review passed.

## Risks

- Deleted companies retain an explicit manual reconciliation outcome.
Recovery does not retry missing credentials or insert a lease for a
deleted company.
- Only Daytona declares automatic creation lookup. Other uncertain
providers retain `needs_reconciliation`. A missing creation name alone
cannot prove that a late allocation will never appear.
- Pending operations use the existing process-local signal and startup
recovery model. This does not add cross-replica wake delivery or prove
deployed sleep.
- Legacy direct provider probes and custom-image setup use separate
lifecycles. They are outside this replacement of the run-lease
orphan-file fallback. The normal Test path that acquires a runtime lease
is covered.
- Existing orphan files still require the separate cutover inventory and
settlement. This change does not delete them.
- The schema change is additive. The new SQL can be reapplied.
Historical SQL and journal entries are preserved; only the oldest
generated snapshot is pruned.

## Model Used

OpenAI `gpt-6.1-sol`, with tool use, code execution and repository
review. The harness did not report the context-window size.

DottaandPaperclip 0e15c92073 feat(skills): make managed content independent of web-server disk (#18334)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Agents use installed skills and exact version pins during execution.
> - Managed skills still depended on mutable directories on the web
server.
> - A replacement server could lose acknowledged edits or remove an
unassigned skill whose directory was absent.
> - This pull request makes immutable versions the authority for managed
content and installed repository reads.
> - The server can rebuild delivery files from durable content after
replacement.
> - This establishes skills readiness for ephemeral web servers. General
server draining and workspace recovery remain separate work.

## Linked Issues or Issue Description

**Subsystem affected**

Skills services, shared contracts, database receipts, Skill Studio, and
runtime delivery.

**Problem or motivation**

A fresh web server must discover, read, edit, and deliver protected
installed skills using the same database, object storage, secrets, and
supported application artifacts. It must not need its predecessor's
files or process memory.

**Proposed solution**

Use `managed` ownership with a null source locator. Read installed
content by immutable version. Prepare packages before a short
publication transaction. Persist execution selections before
materialization. Recover exact pinned runtime assets and reject deletion
while active or recovering pins exist.

**Alternatives considered**

Reconstructing a mutable installed directory preserves the old
source-of-truth ambiguity. Permanent dual writes create two competing
authorities. This change uses one managed model after a bounded legacy
conversion.

**Roadmap alignment**

This improves the existing Skills Manager, Studio, version history, and
Cloud execution capabilities. The maintainer supplied the implementation
contract. This does not add a separate skills product or deploy fleet
changes.

Related work: #18082 supplies immutable package storage. #17273
addresses edits outside the API for linked local skills; this PR keeps
that source category separate. #2648 is a closed earlier
ephemeral-filesystem proposal.

## What Changed

- Add managed ownership and focused content publication and execution
materialization modules. Keep the archive format and package storage
tables.
- Publish managed create, save, delete, fork, rename, restore, and
catalog content with version checks. Add durable create receipts.
Preserve file-save receipt responses.
- Return file version identities. Keep Studio drafts after a conflict
and provide an explicit reload action. A delayed reload cannot overwrite
newer typing or navigation.
- Persist exact runtime selections, including empty selections. Rebuild
pinned assets and verify their admitted digests on a replacement server.
- Preserve source access on forks and disconnected copies. Keep the
existing workspace policy category for managed skills.
- Add bounded conversion, eligibility, and independent verification
phases. Load persisted Cloud configuration in the standalone CLI without
seeding or changing it. Reject partial current versions against
installed inventories; recover only complete saved content or the exact
source. Document storage migration blockers and the compatible rollback
floor.
- Add separate-process PostgreSQL/S3 qualification and update domain,
retention, policy, and UI regressions.
- Pass the plugin worker manager into Studio execution, admit restricted
`skill_test` mode through native Runner contracts, and preserve admitted
scope across native and REST tools. Native tests cannot create ordinary
tasks, browse company data, or use external tools.
- Select the exact durable Studio revision even when unassigned or Beta
skills is off. Persist Studio output and audit atomically with native
task completion, preserving the result on replay.

## Verification

- Final revision `13e8af480b88ba6fea5737bac4bd81104d604792` passed full
CI: all 49 workflow jobs completed successfully ([run
41127396098](https://github.com/paperclipai/paperclip/actions/runs/41127396098)).
This includes typecheck, test suites, Runner checks, browser checks and
build. Greptile review 15 is 5/5 on that same revision, with zero
unresolved threads. The PR is ready for review.
- Local workspace typecheck and build passed after integrating master.
Focused checks passed: 33 execution/completion cases, 52 Runner HTTP
cases, 16 managed-content cases, 17 Studio cases, the new real-process
CLI regression, map checks and UI token gates. The CLI regression proves
inspection does not seed missing Cloud configuration. Server typecheck
passed after that fix.
- The independent-process PostgreSQL/S3 matrix passed through normal
HTTP skill routes. It covers A → B → C replacement, lost commit
responses, upload crashes, concurrent saves, binary contents and
executable delivery. Metadata listing and warm selected delivery retain
zero object downloads. Local timing measurements are recorded; they do
not establish hosted latency.
- Hosted A → B → C passed on the owned disposable test tenant with
external Postgres, S3 and a real remote Paperclip Computer. Predecessor
temporary homes were absent. C read and executed B's acknowledged
managed save. New runs used repository v1 while v2 was installed. Hashes
matched an independently checked exact upstream commit.
- Compatible image rollback to `6518b323` passed. Studio retained the
unassigned fork's C save. A fresh remote run executed the newer managed
content and historical repository pin. The actual shell event confirmed
expected hashes, stdout, exit 0 and mode 0555.
- Runtime candidate `9200e3fcb4` deployed successfully ([Cloud run
41124147876](https://github.com/paperclipai/paperclip-cloud/actions/runs/41124147876)).
The final Studio test delivered only the unassigned fork's exact v3,
executed its script and persisted a successful output snapshot.
Independent command-event inspection confirmed all three hashes, stdout,
exit 0 and mode 0555. All 14 installations were version-backed.
Independent verification checked all 25 versions: 23 remote objects, two
bundled database snapshots, zero blockers.
- The deployed image is `9200e3fcb4`. Later master integration, the
client-only delayed-reload draft guard and the CLI bootstrap have
separate automated proof. The CLI bootstrap was also exercised against
the tenant's stored configuration and storage through the same read-only
services. This PR does not claim that the deployed image is the final PR
revision.
- Live Studio checks exposed worker wiring, admission, access scope,
exact selection and completion-publication gaps. They are fixed. Failed
attempts remain in the evidence. The full local suite exceeded 80
minutes under host contention and was stopped. Later combined/isolated
local attempts also timed out; they are not counted as passes. Full CI
covers the integrated suites. Earlier CI found an obsolete restart-scope
fixture, which was corrected and passed all 52 HTTP cases.
- Reproduction and migration:

history:
[`doc/plans/2026-10-30-ephemeral-web-skills.md`](doc/plans/2026-10-30-ephemeral-web-skills.md).

## Risks

- Legacy conversion requires stopped admission and retired
filesystem-authoritative writers. Pre-conversion binaries are not
supported rollback targets afterward.
- Cloud readiness requires remote object storage. Local provider
receipts and provider mismatches remain blockers until objects are
copied and verified.
- Linked local sources retain filesystem semantics and are outside the
cloud guarantee.
- Cold reads still fetch the existing archive format. Warm runtime
preparation retains the verified-cache path.
- Bundled reconciliation preserves an installed head. Existing release
snapshots remain selectable. An older server must not replace a newer
head with its shipped files.
- No production volumes, fleet defaults, or general deployment
coordination change in this PR.

## Model Used

OpenAI Codex, GPT-6 family, with reasoning, repository tools, code
execution, and browser use. The exact backend model ID and
context-window size are not exposed in this session. No subagents were
used.

DottaandPaperclip f1911a4c53 perf(skills): move repository packages out of Postgres (#18082)
<!-- entire-trail-link-start -->
https://entire.com/gh/paperclipai/-/trails/205/changes/paperclip/205
<!-- entire-trail-link-end -->

## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Agents receive selected company skills before each turn.
> - Imported skills can need files from the whole source repository.
> - The current path stores those files in Postgres and reads large JSON
payloads during preparation.
> - This pull request stores verified packages in the configured file or
object store and keeps preparation queries small.
> - It also converts old rows automatically and restores missing files
from the exact saved commit.
> - The result reduces database traffic while preserving skill versions
and repository dependencies.

## Linked Issues or Issue Description

**What existing behavior does this improve?**

Company skill import, version storage, and preparation before agent
turns.

**Current behavior**

Repository snapshot bodies live in JSONB. Skill preparation can read
those bodies again even when the files already exist on disk. Historical
packages and native assets also need a bounded cleanup path.

**Proposed behavior**

Store package archives and manifests through the existing storage
service. Keep version identities, receipts, hashes, and recovery
metadata in Postgres. Convert legacy rows after the stored package
passes read-back verification. A missing package can use legacy bytes or
its exact Git commit under current repository authorization. No separate
data-migration command is required.

**Reason and benefit**

The warm path sends no repository bodies through SQL and reads no object
bytes. Cleanup runs through the existing deadline coordinator. Current
versions, active runs, explicit pins, and authored content retain their
protection.

**Breaking changes**

The normal application schema upgrade is required. Single-version and
skill-file responses keep their existing shape. Version lists,
current-version summaries, and test-run version summaries now contain
file names and kinds without file bodies. Diff and restore fetch
selected versions through the existing single-version endpoint. Older
server builds must not write after conversion unless they support the
new package format. The storage override and rollback limits are
documented in `doc/skill-package-storage.md`.

**Additional context**

Related work: #15731 preserves repository dependencies; #17923 changes
version-cache scheduling; #18080 changes delivery to remote Codex homes.
This change owns package persistence, acquisition, and expiry. It does
not replace those delivery or scheduler changes.

## What Changed

- Add company-scoped archive receipts, exact-commit recovery recipes,
migration deadlines, and a durable object-deletion queue.
- Add bounded archive upload, read-back verification, extraction,
concurrent request coalescing, and verified local caches.
- Convert old snapshots and versions automatically. Keep legacy bytes
when verification fails.
- Recover missing files through current source authorization and the
original commit. Validate repository identity, file hashes, modes, and
the aggregate hash.
- Expire unused recoverable Git packages and native assets after 30
days. Preserve active pins and the durable copy of authored or unproven
content.
- Keep warm preparation queries metadata-only. Bound file digest caches
and avoid repeated body hashing when file identities are unchanged.
- Extend the existing storage contract with cancellation. Register
package work with the existing coordinator. Optional conversion retries
retain the original bytes and may wait for ingress without blocking
sleep.
- Add regression tests, operating guidance, a deep trace, benchmark
receipts, and an optional maintenance command.

## Verification

### Final master integration and review repair — October 29, 2026

Current head: `a6065424249e763dfeac37161f1b52a9f25bd9b7`. Commit
`f8bbdd3dbd` resolves the conflicts with master `76a796e964`; the final
two commits repair the Apex deletion findings below.

- Keep both package-maintenance and version-retention notifications in
their write transactions.
- Keep the shared run-pin predicate and master's controller-lease
deadline metadata. Package expiry reads the updated protected-version
result.
- Preserve every master migration entry. Generate migration **0415
(`0415_zippy_zemo.sql`)** after master's 0414. Its skill SQL is
byte-for-byte unchanged from the previously tested idempotent migration.
Retain only the five newest schema snapshots. Migration numbering and
safety checks pass.
- Repair failed file/folder deletion: preserve a complete temporary
subtree until transaction commit, restore on upload or SQL failure, and
restore callback failures before releasing the mutation lock. Both
PostgreSQL regressions reproduced missing files before the fix and now
pass. They cover binary data, executable permissions, empty folders,
unlisted files, unchanged database/version rows, successful retry after
upload-claim expiry, and historical reads.
- Reconcile lost commit replies under the same advisory and row locks.
Check the saved version and source identity before restoring. Keep
committed deletions intact and preserve backups when the database
outcome is unknown or a newer edit exists. Four real-PostgreSQL outcome
tests pass; the prior code failed three of them.
- Full workspace typecheck and production build pass on the final
commit. All **204** focused PostgreSQL package/cache/retention/authoring
and filesystem-boundary tests pass, with none skipped.
- Apex review **18 passes 5/5**, with zero new comments on the exact
final head. All **34** review conversations are resolved.
- [Final-head
CI](https://github.com/paperclipai/paperclip/actions/runs/40914116508)
completes successfully on attempt 2. The head has **55 successful
checks**, two neutral reports, two skipped checks, and a successful Snyk
status. No checks are pending or failing. All eight browser shards pass.
- Runner Vitest 2/2 timed out once in the unchanged ACPX
controller-replacement fixture. The same job passed on the preceding
commit. One unchanged CI retry passes all five ACPX recovery cases,
**2,253** Runner package cases and **126** native server integration
cases; their standard one and five skips remain. The initial timeout's
root cause is not established. Local diagnosis also hit the fixture's
eight-second session.open timeout with an authenticated Runner; no local
Runner pass is claimed.
- Both full local `pnpm test:run` attempts were stopped when Apex
identified deletion defects and source repair became necessary; neither
is claimed as a passing full local run. The final **204** focused tests,
full workspace typecheck, and production build pass. Full-suite
acceptance uses the final-head CI jobs. The superseded merge-head CI
included runners terminated by shutdown signals; each source repair
started a new full run.

- Auto-merge is enabled for squash merge. The final head is
conflict-free and all checks pass. GitHub's active master ruleset still
requires a code-owner approval for the dependency files. The existing
review requests are with `devinfoley`, `nickyleach`, and `forgottendev`;
no policy bypass was used.
- The earlier hosted stress and full native receipts below remain tied
to `a2e597d800`; they are not relabeled as a deployment of this final
integration. The earlier local PostgreSQL startup failure remains
recorded below; PostgreSQL ran successfully for this integration
verification.

### Full native skill execution — October 29, 2026

The full native-agent acceptance gap is closed on candidate
`a2e597d800eb989d565780e7aa947d5368676444`. Two qualifying native turns
used OpenAI API / `gpt-5.4-mini` in real Daytona sandboxes, on the same
disposable hosted TEST tenant as the stress test. A follow-up on the
same task consumed a newly saved skill version.

The task text asked for the assigned skill workflow. It did not contain
the proof nonce or expected receipt. The assigned authored skill
contained a Python verifier and a random package-local nonce. The agent
read the actual installed skill files and executed that verifier against
the imported, automatically converted 1,360-file repository package. It
checked the repository file count and reference/binary bytes, and
directly executed the repository's executable probe. Independent
verification matched the emitted JSON to the nonce and expected byte
hashes. The agent persisted the same receipt as its task response;
native finalization committed, workspace finalization succeeded, and
task state became Done.

| Qualifying turn | End-to-end run time | Recorded skills.prepare |
Repository files | Binary hex | Shell receipt SHA-256 |
|---|---:|---:|---:|---|---|
| Initial task | 47.881 s | 1822 ms | 1360 | `00ff07800a` |
`a1deb30dc095f2306c7aa9cc5ec396da12c68961cf5b809f4d7c20f7fc68493b` |
| Corrected follow-up, new nonce/version | 37.974 s | 377 ms | 1360 |
`00ff07800a` |
`dbcdc33fa1376b4edc136feae1cdf770560a73292467e93619efdda20e4282a7` |

Both successful shell receipts reported `probe: STRESS18082` and
`assetSha256:
e8ea7a2f15f7bb3b332a46adbef848465884c8996595aa234748befd544d1f3a`. Their
proof nonces, selected version IDs and receipt hashes differed, and both
ran on the same task. These are observed timings, not latency SLOs; they
include real provider work. The service stress-test timings remain a
separate measurement boundary.

Earlier failures remain in the evidence:

- The original five-minute Daytona allocation timeout never reached
model execution. After normal owned-stack restore, its durable cleanup
record was `expired` / `success`. The cause of that original allocation
timeout remains unknown; a later success establishes recovery only.
- Initial continuation setup used unsupported generic agent-update
fields and returned HTTP 409 before dispatch. Setup was corrected to use
the supported skill-assignment and versioned instruction commands.
- The intervening completed native turn read repository bytes and ran
the probe, but omitted the verifier JSON under the older test agent's
overly-specific instruction file. Its strict receipt validator failed;
it is not counted as a qualifying turn. Correcting the test agent's
instruction file and sending an explicit task-scoped wake produced the
qualifying follow-up above.
- The pinned application's immutable rate card omits `gpt-5.4-mini`, so
completed usage triggered the normal block-on-unpriced budget policy.
Supported append-only accounting corrections estimated the three
completed runs using the [official OpenAI model rate
card](https://developers.openai.com/api/docs/models/gpt-5.4-mini): $0.75
input, $0.075 cached input, $4.50 output per million tokens, assuming
standard processing. Estimates totaled 12.482655 cents. Original usage
and missing-price records are preserved; the $1 hard stop and
unpriced-usage guard stayed active.
- Model shell attempts included a missing `xxd` command and incorrect
guessed file paths. Those failed calls and subsequent successful actual
verifier calls remain visible in complete event streams. No
zero-tool-error claim is made.

No product source changed during this continuation. The previously
measured contention, cold-start and memory limits remain. The later
merge resolution is covered by the separate integration checks above;
these hosted receipts qualify their recorded candidate.


### Hosted stress test — October 29, 2026

**Hosted acceptance:** full native-agent execution and a changed-skill
follow-up pass on the recorded hosted candidate. The final integration
section above records the subsequent conflict resolution and its
separate checks.

Tested baseline `929e840595c8933ca485ac7a2e99413e1e11ca64` and this
exact candidate sequentially on one disposable TEST tenant, with
external Neon PostgreSQL and actual S3. The fixture contained **1,360
files / 22.4 MB / ten skills sharing one repository**. Measurements
cover deployed skill-preparation and native-context services in an
adjacent diagnostic process, not a complete agent turn. The container
had **24 vCPU / 24 GB**.

| Warm workload | Median before → after | p95 before → after | DB
returned value bytes/preparation before → after |
|---|---:|---:|---:|
| One skill, serial | 1,060 → 125 ms | 1,303 → 155 ms | 22,610,389 →
1,771 |
| One skill, four concurrent | 4,415 → 297 ms | 5,143 → 328 ms |
22,610,389 → 1,771 |
| Ten skills, serial | 5,723 → 535 ms | 6,057 → 600 ms | 224,739,030 →
10,671 |
| Ten skills, four concurrent | 24,410 → 1,986 ms | 24,833 → 2,221 ms |
224,739,030 → 10,671 |

- Candidate warm preparation performed **zero S3 GETs**. Ordinary-pool
queries fell from 16 to 9 for one skill and 61 to 9 for ten, excluding
dedicated lock connections. DB numbers measure returned values before
Drizzle decoding, not wire bytes. Baseline/candidate sample counts were
30/100, 32/100, 5/50 and 8/48 respectively; the small baseline ten-skill
samples are comparative evidence, not SLO estimates.
- **Application-UID soak:** 800 ten-skill preparations over 10.3
minutes, four workers paced by 2.5 seconds; **zero failures**, median
**559 ms**, p95 **775 ms**, p99 **910 ms**, zero warm S3 reads. All 726
accompanying health/company-list requests returned HTTP 200. Their
end-to-end p95 was 569/502 ms, including network latency. The probe
overlaps most of the soak. Soak DB-response capture was limited to its
first 60 seconds.
- **Important remaining costs:** an unpaced 16-way ten-skill burst had
p95 **8.32 seconds** because company-level preparation serializes. Cold
preparation took approximately **1.1–2.5 seconds** for one skill and
**7.4–10.0 seconds** for ten. Ten-skill diagnostic RSS remained about
**1.17 GiB** (baseline 1.18 GiB), and the soak peaked at **1.35 GiB**. A
concurrent whole-container sample was 3.45 GB. This does not establish
suitability for a small-memory host or eliminate per-entrypoint native
asset duplication.
- **Upgrade without a manual data migration passed:** legacy snapshot
JSON shrank from 22,465,691 bytes to `[]`, with a stored package and
zero pending conversions.
- **Recovery passed:** sixteen concurrent cold requests coalesced into
two S3 GETs; full bytes/binary/executable modes matched; same-size
corruption repaired; an injected storage failure preserved warm access
and failed cold access safely. A disabled public-Git source denied
recovery, and after the actual five-minute backoff its exact SHA
reconstructed all 229 files. Cross-company descriptor access was denied.
Private-Git credential revocation was not tested.
- **Retention passed:** reclaimed 27,754,496 allocated cache bytes,
deleted an unreferenced package row and both objects, preserved aged
authored history, and expired/reacquired reconstructible Git content. A
version pinned by the failed native run was correctly retained. Only
owned fixture timestamps were aged.
- **Browser UI passed:** authored skill creation, saved edit surviving
reload, version history, and restoration of earlier content.
- **Initial native attempt (superseded by the qualifying turns above):**
one real run failed at Daytona allocation after five minutes
(`setup_failed`), before any model execution. Provider cleanup also
reported failure. That attempt does not count as a passing native turn.
Its receipt and all evidence remain preserved; its cleanup later
recorded success after normal restoration.
- Initial A/B commands ran as SSH root. Diagnostic-owned lock/cache
permissions caused one setup HTTP 500 and the first UID-1000 soak to
fail; exact fixture paths were repaired. The final soak, retention and
recovery ran as application UID 1000. A fresh UID-1000 one-skill batch
also passed (30 samples, median 116 ms, p95 321 ms, 1,771 DB value
bytes/preparation). Earlier harness-export, SSH, npm provenance, backoff
and UI-wait failures remain recorded alongside their successful retries.
- Private evidence includes raw timings, assertions, HTTP probes,
screenshots and failure/cleanup receipts. Initial failed-campaign
cleanup suspended and retained the owned TEST tenant and released the
shared QA account lease at **15:22:41 UTC**. The tenant was subsequently
resumed under its existing ownership for the native execution
qualification above. Final cleanup completed at **15:53:09 UTC**: the
account lease is released and the tenant is suspended/retained under the
original October 30, 12:24:52 UTC retention deadline. Its separate stack
lease remains held; no active or pending-cleanup environment lease
remained. The original retention window is deliberately preserved even
after successful continuation.

- Earlier hosted-tested head:
`a2e597d800eb989d565780e7aa947d5368676444`, integrated with master
`929e840595`. The earlier merge conflicts were resolved at this head.
[Current-head
CI](https://github.com/paperclipai/paperclip/actions/runs/40884087629)
passed; all checks are complete with 55 successes, two neutral reports,
two skips, and no failures. [Apex review
15](https://github.com/paperclipai/paperclip/pull/18082#issuecomment-6480257258)
passed 5/5 with zero findings on this exact head. All review
conversations are resolved.
- Ten real-filesystem boundary cases and server typecheck pass locally
for the security fix. Coverage includes cache roots, descendants,
individual files, symlink aliases, recursive ancestors, a future
concurrent cache fill, and allowed sibling directories. [Current-head
private-project integration
tests](https://github.com/paperclipai/paperclip/actions/runs/40884087629/job/123483306405)
passed all 29 cases, including authorized and unauthorized imports of a
cached private package. Full typecheck, build, server suites, all eight
browser shards, and Runner checks passed in current-head CI. Local
database tests could not run because PostgreSQL could not initialize;
this limitation is recorded below.
- The earlier generated migration preserved the newest five snapshots.
The final integration renumbers its unchanged SQL to 0415. Migration
safety/numbering checks pass. Its SQL is byte-for-byte identical to the
previously verified idempotent skill migration; repeated application on
this latest schema was blocked by the same local database startup
failure.
- The broader verification before the final migration-only rebase passed
1,025 package, lifecycle, remote-launch, native-session, and
asset-retention tests, 52 focused UI tests, full workspace
typecheck/build, token gates, and map checks. The linked complete CI run
passed before the latest focused fixes.
- A disposable MinIO instance passed multipart upload, verified
read-back, and cold restoration of an 18 MB archive.
- Twenty warm samples with a synthetic 1,349-file, 22.8 MB repository
retained five metadata queries and zero object reads. Median preparation
was 256 ms for one selected skill and 691 ms for ten, with 5 ms emulated
network delay each way. These are local measurements, not production
latency guarantees.
- No production instance was changed. Earlier verification failures and
their disposition are retained below.

<details>
<summary>Earlier failures, review findings, fixes, and rerun
evidence</summary>

- The first CI pass found a stale inventory-span expectation and a
missing repository-read span. Both are fixed; all three observability
tests pass. One browser test copied page text into its YAML parser after
reload; its first unchanged-head retry passed, but the race recurred
after rebasing. The test now waits for the renamed URL and completed
reload before copying the editor, retaining its original assertions. The
earlier full local suite did not complete cleanly: it reported setup
timeouts and assertions, while isolated relevant reruns passed. The
complete current-head CI run closes that broad verification gap. No
production instance was changed.

- The first Apex review scored 2/5 and identified six issues. The fixes
protect authored history even when it shares an in-flight Git upload,
recheck upload expiry during orphan deletion, bound failed-upload
cleanup, retain per-version kind/encoding metadata, add sanitized
failure diagnostics, and correct the migration guide. The final focused
run passes all 140 tests; the preceding eight-file run passed all 149
tests, including local storage and S3 diagnostics. Server typecheck and
migration safety/numbering checks pass after the fixes. The second Apex
review scored 1/5 and found unbounded maintenance storage calls and
mismatched package/Git batch limits. Those are fixed with a 30-second
cancellable cleanup deadline, shared 100 MiB/10,000-file scanner and
storage limits, and bounded Git read batches. The proposed manual
lockfile edit was rejected with evidence of the enforced CI-owned
lockfile policy. All 19 storage/recovery unit tests and server
typechecking pass. The new database-backed cleanup/conversion tests were
locally skipped because the host exhausted its PostgreSQL semaphore
capacity (confirmed directly by initdb). That gap is closed by
current-head CI: [package-store
tests](https://github.com/paperclipai/paperclip/actions/runs/40771320775/job/123109300889)
pass all 18 cases and [package-worker
tests](https://github.com/paperclipai/paperclip/actions/runs/40771320775/job/123109301157)
pass all 7, with no skips in either suite. The corrected YAML browser
shard passes. A separate planning-fixture test failed its cleanup DELETE
with an activity-log foreign key violation after its behavior assertions
passed; its one unchanged-head retry passed. The third Apex review
scored 1/5 and identified a one-slot pool deadlock, projected path
limits, cleanup holding the preparation lock during archive reads, and a
publication/expiry race. These are fixed with transaction-local reads,
prefix-aware bounds, isolated verification, and shared package row locks
with a publication grace. The separate Paperclip review also found stale
historical inspection, eager history downloads, and conversion retries
blocking sleep. Those are fixed. Local PostgreSQL capacity recovered:
the new database regressions ran, including the one-slot fork, paused
storage during a warm turn, and a locked publication during expiry. The
expanded run passed 144/145 tests; its remaining assertion still
expected file bodies from the version list and was updated to fetch the
selected version. The corrected company-skill suite passes all 81 tests,
and the final package/projection run passes all 27. All 52 focused UI
tests pass after updating their query-provider fixtures; the first UI
run exposed a fixture remount, and the follow-up exposed an editing
syntax error, both corrected. Full workspace typecheck and build, token
gates, and map checks pass. The sandbox initially blocked the build
tool’s local IPC socket; the authorized build rerun passed. Master then
claimed migration 0401. The branch is rebased on f8226b0515, the
unchanged SQL is regenerated as 0402, and repeated application passed
twice on the combined schema. Post-rebase workspace typecheck passes.
All 1,025 package, lifecycle, remote-launch, native-session, and
asset-retention tests pass on the combined head. All CI checks passed
for head 9d80a3b52d. The fourth Apex review scored 3/5 and found a
save/edit lock-order cycle, a retry retaining an uncommitted source ID
in its recovery recipe, and a summary read racing conversion. Commit
b7d9237c6a fixes all three. The new concurrency and retry tests pass
within all 61 package/source tests, and server typecheck passes. Master
then claimed migration 0402. The branch is now rebased on 65fa1cd617 and
the unchanged SQL is regenerated as 0403. All 68 package, source, and
worker regressions, server typecheck, migration safety/numbering, and
repeated migration application pass on current head 62553671a0.
Subsequent verification and review outcomes are recorded below.


- The fifth Apex review scored 4/5 and found cached version reads
unnecessarily depending on object storage and conversion reads missing
the coordinator cancellation signal. Commit 1eb90d80be fixes both:
cached reads verify bytes without the preparation lock; manifest and
archive reads carry cancellation through conversion. The first focused
run passed 70/71 tests, including all three new cases, but the existing
diagnostic test observed no warning. Its fixture now sets an explicitly
expired migration deadline; the final worker suite passes all nine
cases. Server typecheck passes.


- The sixth Apex review scored 4/5 with one finding: concurrent cached
inventories were unbounded. Commit 4b7589e14c gives cached inventories
and previews a two-reader/32-waiter limit independent of cold storage.
The first expanded pressure test observed a third reader before the
preview path had the same bound; both paths now share the local limit.
All 73 focused cases pass, followed by all 29 package cases after the
final overload adjustment; server typecheck passes. The separate
Paperclip review found no must-fix or should-fix issues. Its optional
suggestion to persist durability verification was considered: cleanup
intentionally verifies current external bytes before discarding the last
local authored copy, and the missing-object regression requires that
check. Shared-package eviction happens on cold fills with at most two
attempts and a ten-second budget.


- The seventh Apex review reached 5/5 with one remaining P2:
timeout-bearing manifest reads bypassed request coalescing. The security
review also found repeated archive acquisition after a cold
administrative read. Commit 79a80a39d2 shares manifest loads with
per-caller cancellation and cancels the underlying work when the last
caller leaves; coalesces identical cold version/file requests; and
publishes verified restored packages into the shared cache. Publication
uses a short nonblocking lock, while eviction verification runs outside
it. The first expanded run passed 73/74 tests and exposed a missing
originating DB for cache publication inside read-only inspection;
transaction readers now pass that owner explicitly, keeping metadata on
the transaction. The corrected run passed 75/75. A final eviction test
initially expected the shared package to remain after only its separate
runtime projection was reused; it now explicitly accesses the shared
package during verification. All 32 final package tests pass, including
independent caller cancellation, one acquisition across
concurrent/repeated reads, and warm preparation during stalled eviction
verification. Server typecheck passes.


- The eighth Apex review scored 4/5 with one finding: decoded cold
inventories outlived the storage semaphore while waiting for cleanup.
Commit 9d7921d1ec adds a separate two-response/32-waiter lifetime bound
held through cleanup, preserving the independent warm-read queue and
forwarding cancellation through eviction verification. The new
regression pauses cleanup after two responses decode, verifies a third
archive stays queued, and completes warm preparation before releasing
cleanup. All 77 package/source/worker cases and server typecheck pass.
On the preceding head, serialized server shard 6/9 was interrupted with
“The operation was canceled” after 57 seconds of tests; the log contains
no failing assertion. Fresh latest-head CI reruns that shard along with
the other gates.

- The ninth Apex review scored 4/5 with one P1: cold responses could own
both permits while waiting on a one-slot ordinary database pool held by
a queued transaction reader. Commit a94f0e409f reads caller-scoped
metadata before admission and isolates all acquisition/cleanup SQL on a
private connection. The new real-PostgreSQL regression reproduces the
deadlock against the previous head and passes with the fix; all 78
focused cases and server typecheck pass. The previous CI run completed
with 54 successful checks, including both formerly interrupted/stuck
serialized shards.

- The tenth Apex review scored 4/5 with one P1: preloading legacy bodies
before admission could retain many full repositories in queued requests.
Commit 276e353a37 removes that preload and also bounds legacy manifest
derivation/fallback, using private connections inside the I/O slot. All
80 focused tests pass; the final synchronized package suite passes all
36 tests and server typecheck passes.

- Apex review 11 returned 5/5 with zero comments on 276e353a37. While it
ran, master 8bc051245f added migration 0403, creating a metadata
conflict. Merge commit e1783764d9 integrates master and generates
0404_clumsy_leo.sql; its skill SQL is byte-for-byte identical to the
previously verified migration. The combined schema passes migration
safety/numbering, repeated SQL application twice, all 80 focused
PostgreSQL tests, full workspace typecheck, and full build. The
preceding a94f0e409f CI run was superseded and cancelled while its final
runner job was active; no old-head success is claimed for that run.

- Final acceptance: Apex review 12 returned 5/5 with zero comments on
e1783764d9. All 28 review threads are resolved. The final head has 55
successful checks, two neutral reports, two skipped checks, and no
pending or failing checks; the PR workflow completed successfully.
Superseded run 40789121902 was cancelled to free its workflow slot for
the final head; normal cancellation did not finish promptly, so force
cancellation completed it.

- October 29 conflict resolution (867c00673b): master 929e840595 added
installed-selection reuse and bundled relocation, routine cleanup
notifications, a hardened YAML copy helper, and migrations through 0413.
The merge retains those behaviors together with package read scoping and
the public-selection fast path; restricted selections still reauthorize
and the full row read rechecks scope. Generated migration 0414 retains
the existing SQL unchanged. Workspace typecheck/build and migration
checks pass. Local database verification is unavailable: initdb reports
semget / “could not create semaphores: No space left on device”; all 168
cases skipped, and repeated migration application failed at startup.
Docker returned HTTP 500 during container creation, so no Docker test
pass is claimed. Current-head CI must close this gap.

- Apex review 14 scored 3/5 with one P1: a local import could copy
cached private package files into a company-wide skill. Commit
a2e597d800 rejects cache trees and ancestors through a canonical
filesystem boundary, including aliases and ancestors checked before a
concurrent fill. Ten local filesystem tests and server typecheck pass.
The existing private-project integration case now rejects package-cache
imports for both authorized and unauthorized users. The preceding merge
commit’s complete CI run passed, and logs confirm all 168 locally
skipped cases executed successfully: package store 36, sources 35,
package worker 9, runtime selection 4, observability 3, authoring 81.

- Apex review 15 returned 5/5 with zero new findings on a2e597d800. The
separate Paperclip review found no must-fix or should-fix issues. Its
optional suggestions were considered: unexpected filesystem cleanup
failures remain visible, the durable marker cannot replace checking that
bytes still exist before deleting a last local authored copy, and
administrative history batching remains outside the pre-turn
optimization. The cache-path literal centralization suggestion is also
optional; the current producer and guard use the same directory, covered
by the new integration regression. All review conversations are
resolved.

- Earlier October 29 CI/Apex acceptance: a2e597d800 was mergeable at
that check, Apex review 15 passed 5/5 with zero findings, and all review
conversations were resolved. The hosted verification above records the
later acceptance limits and renewed conflicts. Workflow 40884087629
completed successfully, with 55 successful checks, two neutral reports,
two skips, and no pending or failed checks. The project-skill-sources
job log confirms all 29 cases ran and passed, closing the latest
integration gap. The preceding merge workflow also confirmed all 168
focused database cases ran and passed. No local PostgreSQL or Docker
pass is claimed.

## Risks

- First use after eviction can require storage or Git access. Revoked
grants, removed sources, and unreachable commits can prevent
reconstruction. Recovery never substitutes a newer commit.
- Historical packages without a proven recipe keep durable bytes.
Cleanup favors retention when a run pin cannot be interpreted safely.
- New uploads and conversion use bounded work and persisted retries.
Large initial conversions still add temporary storage and database load.
- Optional cleanup can wait until the next server wake. Supported
notifications assume one owning server process.
- Per-entrypoint native tree duplication and cold preparation cost
remain. The final ten-skill cold sample took 47.6 seconds on the shared
host.
- Generic authored edits can still hold an existing edit transaction
while a package uploads.
- Explicit file/folder deletion uses temporary disk space for rollback.
An uncertain commit with a changed skill or unavailable database retains
that backup and logs its location for recovery.
