## Thinking Path > - Paperclip manages agents and the tasks they perform. > - A parent needs a new notification when a child finishes requested revisions. > - Native completion currently identifies that wake by the parent and child only. > - An already consumed notification can suppress the child's next completion. > - This PR binds ordinary child notifications to the committed status decision. > - A replay keeps the same identity, while a new completion can wake the parent. > - Live evaluation then exposed new child results being swallowed by an active parent. > - The repair preserves that input for a fresh turn and prevents premature Done from discarding it. ## Linked Issues or Issue Description Refs: #15218. The procedure experiments remain unshipped. This fixes native completion wake identity and durable delivery to a busy parent. Related open work: #10559 and #4507 address legacy wake deduplication, #11179 addresses delivery during an active parent run, and #13044 addresses watchdog signals. This PR changes native committed-decision keys and their delivery to an active parent, while preserving exact watchdog behavior. **What happened?** A native child completed, its parent consumed the notification, and feedback reopened the child. The second completion found the old completed wake and created no new notification. **Expected behavior** Each new ordinary child completion can notify the parent. Replaying the same committed completion must not add a notification. If the parent is already running, the new result must remain available for a fresh turn; an unread result must survive a parent Done claim. **Steps to reproduce** Complete a native child, consume its parent wake, reopen and complete that same child, then inspect the parent wakes. The regression fails on unchanged master because only one wake exists after two completions. **Paperclip version or commit** Baseline: `0fe47882cfcb12082035113c59ca96091c46ebfc`. **Deployment mode** Native runner with the standard server and PostgreSQL control plane. ## What Changed - Include the durable status-decision ID in ordinary child completion wake keys. - Defer new ordinary native child completions behind an active parent, carrying the committed decision identity and revised summary. - Keep a parent in progress while that result is still queued, claimed or deferred; recheck before the status commit. Use the existing continuation without reviving cancelled tasks. - Lock the parent before ordinary child status writes, making the notification/Done ordering explicit without upgrading an implicit foreign-key lock. - Cover exact sequential delivery, dispatcher replay, and queued/claimed/deferred versus consumed/current-run completion identities in database tests. - Apply it when the child is also a dependency and when it is only a child. - Preserve the stable key for exact `task_watchdog` origins to avoid repeated watchdog loops. - Extend real database conformance coverage for both relationships, ordinary and near-match origins, watchdogs, revised summaries, and replay. - Reconcile the working checklist with the merged guidance PRs and record the bounded next step. - Reuse the current composer helper for Everyday task creation: capture the returned task ID, preserve the exact prompt and chosen assignee/project, and cover the setup with paused-agent browser tests. The same setup correction is present in both comparison variants. ## Verification **Ready for review and merge at `e2fc0c8e3ddb84dd9bc045704c3d1ecb23ee3447`: both original live cases pass, zero new failures against the frozen baseline, all checks green, CLEAN/MERGEABLE and out of draft. Not merged.** | Profile | Original baseline | Initial candidate | Fixed candidate | | --- | --- | --- | --- | | native Codex / `gpt-5.6-sol` | PASS | FAIL | PASS | | ACPX Claude / `claude-sonnet-5` | FAIL | PASS | PASS | One new pass, one unchanged pass, zero new failures and no pending pairs against the original baseline. The earlier failed candidate is preserved; it was fixed and measured at a new source, not regraded or rerolled unchanged. ### Current source and live evidence - [Completed campaign 37523025407](https://github.com/paperclipai/paperclip/actions/runs/37523025407) and [public report with original screenshots](https://d1p6rlowie26tp.cloudfront.net/runner-e2e/campaigns/gha-37523025407-1/index.html). Report and screenshots return HTTP 200; screenshot bytes match original retained evidence. - Measured candidate `e2fc0c8e3ddb84dd9bc045704c3d1ecb23ee3447`; reused frozen baseline `7d700f43e93e89e4c196f8799b0aa3cef41d20da`. Trusted workflow `88ff98b83d15eaa6640ee1848df4f0ad9bc82af3` is distinct from measured sources; workflow blob `0600886144d3e22ea2e4a38329a79177882f3948`. Prompts, fixture, oracle, model/profile and input controls are unchanged. Both variants include the same composer setup repair. - Both original candidate grades PASS: all 31 checks per cell, parent and child Done, independently tested revised ZIPs, successful cleanup. Exactly one first attempt per profile on this source: 10 actual runs, no retries. Reusing nine baseline runs gives 19 matched runs; the baseline was not rerun. - Claude directly exercised the repair: its revised child completed while the parent was active, the parent's Done claim became InProgress with `native_child_completion_pending`, and a fresh parent turn then completed with the revised artifact. - Both persisted final provider comments refer to the same attachment whose parent-registration hash matches the revised ZIP tested by the original oracle; native final evidence also references that attachment. Codex provides a clickable download link. Claude describes the new `--max-length` behavior but uses a backticked attachment ID, without a clickable URL in the final prose. The artifact is registered on the parent and independently downloaded/tested; prose-link usability remains a presentation limit outside the original oracle. Artifact identity and observed execution do not prove cognitive review. - 68 focused scheduling/conformance/arbiter tests pass. Four regressions fail against the original production files while four controls pass. The database scheduler test proves one sequential continuation with the revised summary and replay deduplication. It uses a mock adapter and is separate from the live proof. - Full local `pnpm -r typecheck` and `pnpm build` pass. [Exact-head full CI 37522126627](https://github.com/paperclipai/paperclip/actions/runs/37522126627): 51 successful checks, two intentional skips, separate Snyk success. Fresh exact-head Greptile [5/5](https://github.com/paperclipai/paperclip/pull/15372#issuecomment-6022179172), no new actionable findings; all review threads resolved. - Ready-transition Contributor trust and Superagent Security Scan both pass. The security scan completed at 2026-10-06T20:26:53Z with zero annotations. Final total: 53 successful check runs, two intentional skips and separate Snyk success; aggregate SUCCESS, source unchanged, zero unresolved threads. - The explicit parent lock precedes child writes. Its controlled PostgreSQL ordering also passes on previous production through an implicit foreign-key lock; this is hardening, not a reproduced additional live failure. The four original failing regressions remain the before/after proof of the active-parent repair. ### Preserved failures and accounting - Initial candidate `a2ae2324ce7692e704fc43e99904b076d6246fee`: Codex PASS → FAIL, Claude FAIL → PASS. Equal totals concealed a new failure and did not qualify that source. Its Codex parent ended Blocked after the revised child result coalesced into the active parent; there was no retained later parent execution and the independent ZIP oracle was never reached. A later server backstop log did not prove recovery. - In the initial Claude cells, both parent finals referenced an earlier parent ZIP while the oracle tested the revised child's ZIP. The original candidate PASS did not establish latest-artifact delivery. Earlier parent ZIP bytes are absent, so different hashes alone do not prove missing functionality. Those original grades and content findings are unchanged. - Original baseline [report](https://d1p6rlowie26tp.cloudfront.net/runner-e2e/campaigns/gha-37509893406-1/index.html); original candidate Claude [artifact](https://github.com/paperclipai/paperclip/actions/runs/37509916344/artifacts/11434353106); failed candidate Codex [campaign](https://github.com/paperclipai/paperclip/actions/runs/37513070706). The original cohort contains 17 actual runs, no retries, successful cleanup. - Campaign 37509916344 was cancelled after its Codex job waited over 16 minutes without a runner or steps. Completed Claude evidence was preserved; only the missing Codex first trial was dispatched in 37513070706. The trusted workflow revision differs but workflow bytes are identical. The cancelled campaign has no published HTML. Earlier campaigns 37506546098 / 37506550087 retain four composer setup failures, zero agent runs; the identical fixture-only repair restored setup without changing the prompt or outcome oracle. - Intermediate `3c1cf6830ce9db4123b834ffb99c594c383a8986` [campaign 37518652522](https://github.com/paperclipai/paperclip/actions/runs/37518652522) was cancelled after a concurrency review finding. Both paid-cell steps started and both tasks were created. Only invocation policies survived; no grade, run inventory or cleanup receipt. Provider activity and charges are unknown: two incomplete attempts, not passes or zero-provider setup failures. - Cumulative accounting: **27 known actual runs** (17 original + 10 fixed-candidate), plus unknown activity in those two cancelled intermediate attempts. The 19-run matched comparison reuses nine baseline runs and is not additional execution. Reported LLM amounts are zero with original billing `complete=true`; actual charges are unknown and local/hosted runtime is unmetered. No free-run, speed or cost claim. - Original and new results pass the canonical result validator. Retained source, input, result/API/story/final-ledger/usage run identities and artifact hashes were audited. Each downloaded package omits the pre-upload-declared `playwright-output/.last-run.json`; primary result, API, final ledger, story, screenshots and reached ZIP oracles are retained. No full-package completeness claim. - The initial redundant local full test invocation was stopped after 2,492.5 seconds once that head's CI passed; completed groups recorded 23,045 passes and 87 skips. That local invocation remains incomplete. Current full CI is the repository-wide test evidence. ## Risks A revised completion can schedule another sequential parent run and its normal budget use. A parent Done claim remains non-terminal while a newer native child result awaits delivery. Company scope, governance, workspace-finalization, terminal cancellation and exact watchdog behavior remain enforced. This changes native completion authority and scheduling, so the durable identity, replay and concurrent-commit controls matter. The two live trials qualify the observed revised-child handoff, not broad task quality or causal/general equivalence. Claude's final prose still gives an attachment ID without a clickable URL, although the registered revised artifact passes the original download oracle. Completion before any new child result exists, removal of unfinished dependencies and broader instruction reduction remain separate questions. There is no schema or prompt change. ## Model Used OpenAI Codex, GPT-6 family, with repository inspection, shell execution and code editing.
