## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - Each task prepares its workspace before it starts the provider. > - Source preparation holds a transaction-scoped advisory lock on a dedicated database connection. > - Preparation can use other connections and the filesystem for longer than PostgreSQL allows that lock connection to stay idle. > - PostgreSQL then closes the connection and releases the lock while preparation still runs. > - This pull request reuses the workspace lock keepalive during source preparation. > - Slow preparation retains exclusion and returns its original result or error. ## Linked Issues or Issue Description **What happened?** Tasks failed during workspace preparation with `CONNECTION_CLOSED` at the configured 60-second idle transaction timeout. No provider had started. A live retry showed the source-lock transaction idle while authorization reads ran on another connection. Its advisory-lock key matched the task's source-preparation key. PostgreSQL closed that transaction at the timeout. The same defect remains on current master. A real PostgreSQL regression also shows that another preparation can enter after the timeout while the original callback still runs. **Expected behavior** Source preparation must keep its advisory lock until the callback and any pending keepalive query finish. The ordinary pool must remain usable. The original preparation result or failure must survive. **Steps to reproduce** 1. Set `idle_in_transaction_session_timeout` to one second in a disposable PostgreSQL database. 2. Call `withIsolatedRepositorySourceLock` and keep its callback active for longer than one second without querying the lock connection. 3. Try to acquire the same source lock from another operation. 4. On the old code, the second operation enters and the first transaction fails with `CONNECTION_CLOSED`. **Paperclip version or commit** Reproduced on source at `cde944ed75648adfb569e86133adc8b118b55dd6`. The repair is rebased onto `d855e550ad`. **Additional context** Refs #16340. That change introduced the keepalive for workspace copyback. This PR applies the existing helper to the source-preparation transaction. ## What Changed - Read the configured idle timeout in the same query that acquires the source lock. - Keep that dedicated connection active during source preparation with the existing helper. - Add two real PostgreSQL regressions for exclusion, company independence, a one-slot ordinary pool, nested acquisition, cleanup, and preservation of callback errors. - Update the execution contract and workspace verification maps. ## Verification - Red before the production edit: both new tests failed. A competing operation entered after the lock expired. A callback failure was replaced by `CONNECTION_CLOSED`. - Green after the repair: 86 tests passed across the source lock, source admission, keepalive, and heartbeat workspace preparation suites. - `pnpm -r typecheck`, `pnpm build`, and `node scripts/check-maps.mjs` passed on final commit `2b5000ce25`. - `git diff --check` passed. The lockfile is unchanged. - After rebase, the same 86 focused tests passed. The two source-lock tests passed again after the review cleanup change. - Live acceptance on `7df94d7a06`: a fresh local instance on macOS arm64, Node v26.4.0, native Codex `gpt-6.1-sol`, and permission mode `never`. PostgreSQL had a one-second idle transaction timeout. A temporary Git wrapper delayed repository reads by four seconds. Workspace preparation after environment acquisition took 8,297 ms. The real task completed, wrote and attached the correct line-count/SHA-256 report, reached `done` with native phase `committed`, and cleared its execution lock. The attachment matched the workspace file and survived browser reload. No dedicated lock connections remained. - The live probe initially used `gpt-5.4`, which the ChatGPT account rejected. Selecting the reported task model, `gpt-6.1-sol`, resolved that readiness failure. The local Claude CLI has no login, so no live Claude run is claimed. - Full CI passed on `2b5000ce25`: all general, chat, workspace, serialized-server, Runner, and E2E test shards, plus typecheck, build, and canary packaging. Both Greptile and Paperclip Review rated this commit 5/5 with no open findings. The Paperclip check concluded neutral; two unrelated visual checks were skipped. - The duplicate local `pnpm test:run` serial invocation was stopped with SIGINT after the complete CI test shards passed. It did not finish locally; no local full-suite pass is claimed. Local proof consists of the focused real PostgreSQL tests, typecheck, build, map checks, and the real task above. - The final commit changes test teardown only; production code matches the live acceptance commit. - Initial sandbox runs could not open test database ports or build IPC sockets. The same commands ran with local process access. The frozen install also found an existing manifest/lockfile mismatch; dependency resolution was local and the lockfile was restored. ## Risks - The lock connection sends one small query per keepalive interval. The helper derives that interval from the configured timeout and caps it at 30 seconds. It does no polling when the timeout is disabled. - The helper joins an in-flight query before the transaction ends. A slow database can therefore delay cleanup. - This change does not disable database deadlines, retry preparation, or recover an unexpected connection loss. It preserves existing admission checks and company/source lock keys. - Deployment and recovery of the reported tasks remain separate from code verification. ## Model Used OpenAI GPT-6 through Codex, with repository tools, code execution, and browser verification. The exact served model variant and context window are not exposed in this session. ## Checklist - [x] I have included a thinking path that traces from project context to this change - [x] I have specified the model used (with version and capability details) - [x] I have checked ROADMAP.md and confirmed this PR does not duplicate planned core work - [x] I have searched GitHub for duplicate or related PRs and linked them above - [x] I have either (a) linked existing issues with `Fixes: #` / `Closes #` / `Refs #` OR (b) described the issue in-PR following the relevant issue template - [x] I have not referenced internal/instance-local Paperclip issues or links (only public GitHub `#NNN` / `github.com/paperclipai/paperclip` URLs) - [x] My branch name describes the change (e.g. `docs/...`, `fix/...`) and contains no internal Paperclip ticket id or instance-derived details - [x] I have run tests locally and they pass - [x] I have added or updated tests where applicable - [x] I have updated relevant documentation to reflect my changes - [x] I have considered and documented any risks above - [x] All Paperclip CI gates are green - [x] Greptile is 5/5 with no open P2s, recommendations, or follow-ups - [x] I will address all Greptile and reviewer comments before requesting merge --------- Co-authored-by: Paperclip <noreply@paperclip.ing>
Paperclip agent access map
This map accompanies the feature map. It records APIs, agent entry points, permission boundaries and verification for the same capability IDs. The shared contract defines the format and maintenance rules.
Browse access contracts
The same-named feature recipes define navigation and capability IDs. Run
node scripts/storybook-catalog.mjs for the generated
maps/generated/agent-access-map.md index, or browse the
published feature guide.
Add or update the affected companion; there is no central registration or count.
Existing baseline source references describe the original inspection, not current verification. Record new executed evidence in the PR, issue, or CI artifact with its revision and scope. Do not refresh unrelated headers as bookkeeping.
Using an entry
Read its Policy and Gaps before selecting an agent path. Native fallback, legacy
REST/CLI, stdio MCP and a personal assistant connection can have different
authority and availability. Use a real admitted production binding; a scenario
declaration is not an installed tool. A restricted entry records current
enforcement and leaves any unresolved delegation decision visible.
For API catalog disagreements, follow the route/service authorization and record
discovery drift. For not-applicable, retain the concrete exception and local
path. Split shared business operations from client-only presentation.
Use maintain-verification-skill to reconcile changed source and both maps.
Use verify-paperclip and existing API/runner/MCP fixtures to collect the
permitted-agent and denial evidence; report blocked/not-run coverage honestly.
Run node scripts/check-maps.mjs after editing. The structural check does not
certify permissions, API catalog coverage, tool admission or live behavior.
Native REST transport
The call_api parity change reconciles affected baselines against
58e16dbddfc9c8d0cf60867f9d9847f0feda055b and the changes in this PR. Ordinary
REST operations use the same route authorization as legacy agent REST. Dedicated
tools remain optional for those operations; protocol endpoints still need their
existing clients. Board-only routes remain restricted for agent identity.
Native search_api / call_api requires operator rollout admission, a running
authorized native run, current task assignment and execution-run binding, company
and budget authority, task privacy, and a permitted work mode. Ask and Plan retain
mutation restrictions, and runs retain their admitted JWT scope during restart
recovery even when task mode changes. A waiting
agent does not gain independent native control just because a REST route exists.
Credential-bearing replies, including company exports and their legacy alias, stay inline under a 10 MiB limit and use encrypted mutation receipts. Other saved API snapshots are limited to the issuing actor and responsible user, plus authorized administrators. Artifact uploads enforce the same access checks as downloads; private snapshots are excluded from company exports and public company logos. Explicit deliverables use the existing sharing path. Native event history, checkpoints and completion records omit API bodies while preserving receipt metadata and replay digests. Restored webhook secrets use the same encrypted receipt and inline response policy as newly created webhook secrets. Task image access requires the company boundary and the task permission; skill-test and low-trust agents do not need company-wide browsing authority. Completion replay applies the same idempotent projection to stored and expected payloads; the run-log guide describes its fields.

baseline and source-only; this reconciliation does not certify every operation.
Targeted real-route proof lives in the
