DottaandPaperclip	a63d19816f	fix(server): wake decision continuations from committed changes (#17478) ... ## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - A completed decision can owe a wake to the agent that proposed it. > - The decision row already stores the pending continuation. > - The main maintenance tick scans this debt even when no continuation is ready. > - Committed changes can activate recovery and leave settled history quiet. > - This pull request gives continuation delivery its own worker and shares foreground delivery ownership. > - Pending work stays recoverable without an unconditional continuation scan. ## Linked Issues or Issue Description Targets master after #17475 merged. This is slice 09 of the recurring server work migration. Each PR owns one reason for background work. The remaining inventory is in `doc/plans/2026-10-24-recurring-server-sleep-stack.md`. **What existing behavior does this improve?** Decision continuation delivery and recovery in the server. **Current behavior** Foreground paths send a wake and clear a pending flag. The combined decision sweep scans pending continuations on every maintenance tick. It can overlap foreground delivery. **Proposed behavior** Terminal decision writes notify a dedicated worker through the existing transaction boundary. Foreground and recovery calls share one in-flight delivery per decision and DB owner. Recovery re-reads readiness, pages past failures, and retries only unresolved debt or errors. **Reason and benefit** Open decisions, running effects, and delivered history no longer cause an independent continuation scan. No queue table is added. Decision expiry, target invalidation, interrupted effects, and retention remain separate duties. ## What Changed - Extract continuation readiness, delivery, and paged recovery into the decision owner. Preserve the wake payload and at-least-once crash behavior. - Signal the ten decision update sites before SQL in their existing transaction scope. Keep effects and wake calls outside those transactions. - Explicitly create the continuation obligation on all three archive-proposal failure settlements, including recovered running rows without inherited pending metadata. - Serialize concurrent decision effect execution through final settlement. Coalesce foreground and worker wakes. Re-read the durable flag before sending. Fence effect completion to running state so competing completion cannot restore acknowledged debt. - Expose an opaque DB work-scope key. Child pools and nested transactions share that identity; independent roots remain separate. Existing signal consumers keep their behavior. - Bound each recovery pass to 100 candidates, retain a fair cursor across failures, and stop between deliveries on shutdown. Forward the existing AbortSignal through the shared deadline adapter. - Register enabled-heartbeat continuation recovery before decision housekeeping. Remove only its independent scan from the main tick. Preserve the public combined sweep and disabled-heartbeat behavior. - Add generated migration `0388_ambitious_micromax.sql`, an idempotent concurrent partial index for pending continuations, and keep five generated snapshots. - Add real producer, transaction, failure, concurrency, paging, quiet, and shutdown tests. Document ownership and remaining limits in `doc/idle-decision-continuations.md`. ## Verification Current candidate: `18f682863cadb91281a86b4da2553a4579ee054a`, normally integrated with landed archive squash `5785090ff1`. All 31 independent incoming master files are preserved exactly, including controller-authority recovery. All 97 decision/startup/deadline cases plus server types/build pass after the required Runner vendor rebuild. The preceding full five-suite selection passed 293 cases; the continuation owner behavior is unchanged by master reconciliation. - **97 cases pass at this master integration** across decision, startup and scoped-deadline suites, plus server types/build. The preceding parent candidate passed the full 293-case decision/gateway/archive/startup/deadline selection; those results remain evidence for that revision. All selected cases executed with separate PostgreSQL fixtures where needed. - Tenant-driven global scan amplification reproduced six sweeps for six sequential real cancellations. Existing thirty-second notification coalescing now permits one recovery sweep per window while retaining pending work. The first green fixture wrongly expected the intent hold to clear before coalesced reconciliation; the hold remains and quiet is checked after settlement. Foreground delivery stays immediate. - The archive contention test uses a signaled dedicated single-connection read and two FIFO SQL round trips instead of a fixed delay. Removing effect coalescing makes it fail with two contender reads; restoring production code passes. No production test hook was added. - **Three new real PostgreSQL regressions failed before repair**: recovered archive proposals with invalid signatures, mismatched manifests or archive execution failures and no inherited pending flag. Each now persists failure, wakes once, acknowledges continuation delivery and remains quiet on replay. Running-state fencing is preserved. - The unmerged continuation index is regenerated as `0388_ambitious_micromax.sql` after parent migrations 386/387. All parent journal entries are unchanged, five generated snapshots remain, numbering/safety and snapshot/schema-drift checks pass. Fresh database migration apply and replay pass; the concurrent index is valid. - Existing lifecycle coverage includes foreground/worker coalescing, child pools, transaction commit/rollback, failed acknowledgement, restart, drain/resume, shutdown and fair 100-row recovery. Earlier bounded-pass and concurrent archive-result regressions and their repairs remain recorded in [the owning behavior audit](doc/idle-decision-continuations.md). - Failure accounting: the first combined command used an incorrect retention fixture variable and skipped 15 cases. The corrected separate external-PostgreSQL retention run passed all 15. The historical nine embedded-only work-signal cases were not executed by this selection. Extra upstream embedded-only suites attempted on the parent could not initialize locally; they remain CI verification, as recorded in the parent PR. Earlier reused-fixture, assertion and compile failures remain in the behavior audit and stack ledger; they are not erased by later passing checks. Commands: `pnpm --filter @paperclipai/server typecheck`, `pnpm --filter @paperclipai/server build`, server Vitest for `decisions-service`, `decision-retention-service`, `server-startup-feedback-export` and `scoped-deadline-work`; `pnpm --filter @paperclipai/db check:migrations`, migration apply/replay, and the generated snapshot-drift test. Local targeted evidence does not establish a full local repository run, deployed sleep or fleet savings. Fresh exact-head CI and both automated reviews remain merge gates. ## Risks - Notification-driven recovery remains global but is coalesced to thirty seconds. This bounds request-driven scans; it does not introduce company-scoped selection. Foreground delivery remains immediate. - Delivery remains at least once. A crash or acknowledgement failure after accepting a wake can send it again. Local coalescing is not a cross-process claim. - Supported writers share the application DB signal owner. Independent SQL writers or multiple active server processes need a separate wake contract. Wake-producing service methods do not gain a new guarantee when called inside an uncommitted caller transaction. - The concurrent index needs top-level migration execution; it is registered with the existing migration owner and can be replayed safely. - No Cloud sleep blocker or external alarm coverage changes. Worker quiet does not prove deployed app or database suspension. ## Model Used OpenAI Codex, GPT-6 family, with reasoning and code execution.

DottaandPaperclip	835a022936	perf(server): wake delivery queues from transaction-aware work signals (#15625) ... ## Thinking Path > - Paperclip manages AI-agent work and its delivery to users and agents. > - Five delivery queues scan the database even when empty. > - Each queue already has durable rows; empty polling wastes idle hosting capacity. > - Producers can register intent inside their existing database transaction. > - Central transaction tracking can wake consumers after the outer commit without extra caller wrappers. > - A lost response needs reconciliation against PostgreSQL before an empty queue is safe to leave idle. > - This change uses one scheduler for outstanding work and lets settled, empty queues go quiet. ## Linked Issues or Issue Description Supersedes the closed #15614. Related idle-safety work: #15522 and #15599. **What existing behavior does this improve?** Delivery scheduling for feedback exports, chat completions, connection continuations, question answers, and tool-action receipts. **Current behavior** Feedback scans every five seconds. Four delivery queues scan on the heartbeat interval, normally 30 seconds. Startup and some event paths also scan them. **Proposed behavior** Each producer awaits one intent registration before its queue write. The existing `createDb` transaction boundary tracks nested savepoints and wakes the consumer after outer settlement. Startup scans restore durable work. Pending rows, failures, and unresolved transactions retain retry deadlines. Empty, settled queues have no timer or recurring scan. **Reason and benefit** Normal delivery starts after commit. Central tracking removes caller-specific post-commit plumbing. PostgreSQL transaction status resolves lost responses without new tables or a permanent uncertainty latch. **Breaking changes** No API or schema changes. The notification scope is one DB owner and its dedicated child pools. Direct SQL, separate roots, and other processes require an explicit wake/recovery integration. This path requires PostgreSQL 14+ transaction-information functions; embedded PostgreSQL uses 18. ## What Changed - Add one named-deadline scheduler and app-owned coordinator for five existing queues. - Instrument `createDb().transaction()` centrally, including nested savepoints. Dedicated child connections share their owner's signal scope. - Register work before the five queue insert paths. The first registration obtains the outer XID; unrelated transactions issue no extra SQL. Tool receipt insertion gains a small transaction around its existing insert. - Query `pg_xact_status` only for rejected, tracked transactions. Probe before scanning the queue. Retain the idle hold while PostgreSQL still reports an in-progress transaction or the probe fails. Release it after settlement and reconciliation. - Remove unconditional delivery recovery scans and caller-specific completion post-commit actions. Retain the existing task-scoped completion activity fast path and durable claims. - Coalesce wakes without postponing an earlier deadline. Retry outstanding rows and failures; suppress dispatch during idle drain while allowing transaction and queue reconciliation; suppress both during warm standby. Cancel deadlines and await active delivery sweeps on shutdown. - Serialize feedback flushes. Vote routes return after saving. Uploads have a 30-second deadline and shutdown cancellation; unfinished exports remain recoverable. - Document the writer contract and update the dated sleep inventory. ## Verification - Final head: `a4609956841107ad60c4cb50fe2acb05636b1363`. - Passed: all final-head hosted checks, with 54 successes and two intentional skips. The full test matrix, typecheck, build, canary, and aggregate verification passed in [run 37940948440](https://github.com/paperclipai/paperclip/actions/runs/37940948440). - Passed: Greptile 5/5 on the same head, with a successful check run and zero unresolved review threads. The branch is mergeable. - Passed locally after the final rebase: 50 coordinator, scheduler, and startup tests; server typecheck; server build. - Passed locally before the final import-only rebase: repo-wide typecheck and build; 237 PostgreSQL producer/delivery and database signal tests; feedback, native-question, and idle-safety regression tests. - Real PostgreSQL tests hold transactions open after an injected client response loss, then commit or abort. They verify that an empty scan cannot clear an in-progress transaction. Another test terminates a real backend and verifies recovery without replay. - Coordinator tests cover an hour with no empty-queue timers, pending/error retries, worker replacement, concurrent writes, earliest-deadline preservation, rollback during idle drain, committed work during drain, standby, and shutdown. - Local `pnpm test:run` was started and stopped after embedded PostgreSQL startup failures appeared. It did not finish and is not reported as a pass. Later local database reruns had skipped suites; those skips are not claimed as verification. The earlier PostgreSQL tests did execute and pass, and the final hosted full matrix passed. ## Risks - One XID query is added per transaction that registers delivery work. Nested transactions share that ID. Registration must be awaited before writing; new enqueue paths must follow this contract. - Work signals are local to a DB owner and its dedicated child pools. Independent roots, direct SQL, or other processes are not observed. Startup scans recover already committed rows, but do not fence late transactions from a previous process. Cross-process ownership and database failover require separate work. - A database outage or genuinely unresolved transaction keeps an idle hold until status can be reconciled. No timer clears uncertainty by assumption. - These changes remove five empty polling loops. They do not implement whole-instance sleep, database teardown, or an external waker. The earliest deadline covers only the registered queues. - Waiting tool reviews retain their existing retry cadence until their receipts can be delivered. - Feedback vote responses no longer wait for the remote upload. Sharing consent and the saved vote response are unchanged. - Real hosting-provider sleep and cost savings have not been measured. ## Model Used OpenAI Codex, GPT-6. Used reasoning, repository inspection, code editing, and command execution. The runtime did not expose the exact model revision or context window. ## 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>	2026-10-09 10:01:26 -05:00
