## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - Recovery must prove that old execution stopped before it admits new user input. > - Explicit continuation reads the source run before and after it takes the run lock. > - Both reads transfer the saved prompt and the full Runner profile. > - The preflight needs only identity, comment, adapter, and workspace receipt fields. > - This pull request narrows those reads and keeps the complete locked profile for session proofs. > - The benefit is less database transfer with the same admission and recovery rules. ## Linked Issues or Issue Description **What existing behavior does this improve?** Explicit native continuation admission after a failed or stopped run. **Current behavior** The preflight and locked reread select complete heartbeat run rows. Large saved contexts and execution profiles cross the database connection twice. **Proposed behavior** Read only required scalar fields and typed context keys. Read only historical adapter identity and workspace sync receipts before the lock. Keep the complete Runner profile in the locked reread. Keep lock order, company scope, text lookup of historical run IDs, stop proofs, queued input, and replay rules. **Reason and benefit** A synthetic PostgreSQL 17 fixture removes 74.9% of the two queries' DataRow bytes. This result is local query evidence. It is not a claim about deployed latency or monthly transfer. **Breaking changes** None intended. No schema, API, migration, workflow, or dispatch contract changes. **Additional context** Related: #17491 narrows the separate execution blocker read path. This PR covers explicit continuation admission. The PR has no dependency on the other byte reduction PRs. ## What Changed - Select required continuation fields and typed context keys instead of complete run rows. - Read a small historical adapter/workspace profile during preflight. Preserve the full locked profile for exact suspended-session and quarantined-cleanup proofs. - Narrow four helper input types to their actual field requirements. Their runtime behavior is unchanged. - Add real PostgreSQL admission comparison coverage and a reproducible baseline/treatment benchmark. - Document the query boundary and benchmark command. ## Verification - Baseline: `663fe667d66d3863d0919a8724f1d99500feef0b`. - Disposable PostgreSQL 17.11. One source run has a 192 KiB incompressible context and two 96 KiB profile payloads. - Command: `pnpm --filter @paperclipai/server exec tsx ../scripts/benchmark-continuation-run-reads.ts --baseline-ref=663fe667d66d3863d0919a8724f1d99500feef0b`. Set `PAPERCLIP_CONTINUATION_BENCHMARK_DATABASE_URL` to a disposable database ending in `_test` to use an external server. - The harness captures SQL generated by both real service versions. Baseline imports use current helpers; only their TypeScript input types changed in this PR. Their runtime behavior stays fixed. - Preflight DataRow bytes: 394,067 to 466 (99.88% less). Locked reread: 394,067 to 197,168 (49.97% less). Combined: 788,134 to 197,634 (74.92% less). - Byte counts cover exact PostgreSQL text-format DataRow frames. They exclude RowDescription, command metadata, TLS, TCP, and other queries in the service. - Seven measured samples per query follow two warmups. The order alternates. Final-head median preflight time: 6.53 to 2.28 ms (ranges 5.34–7.41 and 1.84–4.46 ms). Median locked read: 8.06 to 5.26 ms (ranges 5.94–13.84 and 4.61–6.81 ms). These are warm local SQL measurements under shared machine load. The deterministic byte counts are the acceptance criterion; these noisy timings do not establish a deployed latency gain. - The harness compares the admitted continuation, blocked reasons, every retained scalar column, kept JSON, and the full locked profile. It fails unless the fixture removes more than half of the two reads' DataRow bytes. It records SQL, parameters, revision identity, samples, and EXPLAIN plans. - All 291 continuation tests pass together on the final head with no skips in a clean isolated PostgreSQL 17 database. This includes all seven new projection comparisons and six malformed/missing JSON cases. - Edited server TypeScript check passes: `node node_modules/typescript/bin/tsc --noEmit -p server/tsconfig.json`. - `pnpm -r typecheck` and `pnpm build` pass on the final head. The normal server build verifies the complete pinned Copilot closure. Local full `pnpm test:run` is not claimed: host embedded PostgreSQL startup limits prevent that gate. The isolated PostgreSQL regressions pass; the full exact-head test matrix runs in CI. The targeted exact-head test retry passes all 4,086 tests in 98 files. All CI verification checks and the dependent aggregate are complete and successful on head `47c1b5f7d17a58310f7a3ebd494fdcaa814777c2`. Greptile completed cleanly on head `47c1b5f7d17a58310f7a3ebd494fdcaa814777c2`: 5/5, no findings, and no unresolved review threads. - Local setup evidence: embedded initdb could not load its ICU data library. Tests therefore use a dedicated PostgreSQL 17 container. A run against reused test fixtures produced stale sweep failures; a new clean database passed all 285 cases. The first comparison mock replaced an unrelated aliased query; it was narrowed to the two admission reads before the clean pass. - The first [server test shard 6/12](https://github.com/paperclipai/paperclip/actions/runs/40529210562/job/122277218565) failed one existing workspace-recovery case: a third export stayed `scheduled` at its 20-second poll deadline; 4,085 other tests passed. The exact case passes on the pinned baseline and final head with the same PostgreSQL 17 fixture. Temporary spies recorded zero calls to both changed admission functions in either replay. Other touched helpers have type-only changes. This supports one timing-flake retry; the exact scheduler delay remains unproven. The single [targeted shard retry](https://github.com/paperclipai/paperclip/actions/runs/40529210562/job/122285744135) passes all 4,086 tests in 98 files. The exact case completes in 17.25 seconds. The dependent aggregate is complete and successful. No timeout or unrelated runtime code was changed. - The separate Paperclip Review check ended `NEUTRAL` without a final report. The completed source review is the exact-head Greptile 5/5 result above. ## Risks - A future admission check may need an additional saved context key. Keep the projection and helper contracts in sync with that consumer. - Exact suspended-session and quarantined-cleanup proofs still require the complete Runner profile. This PR retains it under the lock rather than weakening those checks. - JSON values retain their types and missing keys stay absent. Malformed-context comparisons preserve the existing controller hold. - These measurements use synthetic local data. Deployed transfer savings require a fresh capture after rollout. Nothing was deployed. ## Model Used OpenAI GPT-6 through Codex. The exact runtime model ID and context window are not exposed by this session. The work used repository tools, code execution, and real PostgreSQL validation. ## 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>
