feat: rerun a bot turn when its source is edited after completion - #1905
Conversation
An edit to a message a bot had already answered was silently dropped: `insertIdempotent`'s terminal gate excluded any actor with completed, failed, parked or expired work on that source regardless of revision, so the reconcile produced no invocation and no user-facing signal. Personas already rerun on this (`message-mutation-outbox-handler`), but that handler skips bot-invocation sessions. The gate now blocks only terminal work that already covers the incoming revision, so a redelivered outbox event still cannot duplicate a turn while a genuine edit opens a fresh one. The new invocation carries the wording the actor answered, quoted from `message_versions` at the completed turn's revision, and leaves the decision to the agent.

⚙️ CodeRabbit configuration file
apps/backend/src/**: Real-time event delivery must go through the outbox pattern. Do not publish events
directly via socket.io emit or Redis pub/sub outside of the outbox dispatcher. (INV-4)
All AI/LLM usage must go through the project AI wrapper (createAI), not raw SDK
imports from@anthropic-ai/sdkor openai. (INV-28)
Do not keep database connections open during slow AI or network calls. Release the
connection first, then do the slow work. (INV-41)
Never do select-then-update without locking or concurrency control. Use ON CONFLICT,
advisory locks, or transactions with row locks for write paths. (INV-20)
Check-then-act guards must pin the identity or generation observed at read (row id,
integer version, or external key), not just a status flag — status-only guards let
stale work clobber a row that was replaced in between. (INV-20)
Optimistic concurrency must CAS on an integer version column, never on timestamp
equality: PostgreSQL stores microseconds while a JS Date round-trips at millisecond
precision, so a timestamp CAS fails on virtually every uncontended write. Tests for
version- or timestamp-gated predicates must produce the compared value through the
repository's own NOW()-writing code path, never hand-crafted fixture timestamps.
(INV-66)
Avoid withClient for single-query paths. Pass pool directly instead of acquiring a
dedicated client. (INV-30)
Validate API inputs (body, query, params) with Zod schemas, not manual typeof
checks. (INV-55)
Stream access is inherited through root_stream_id: threads never carry their own
access, and public root streams grant read access without a stream_members row.
Any new query or filter gating rows on stream membership/visibility must reuse
checkStreamAccess / listAccessibleStreamIds (features/streams/access.ts) or
replicate the thread-to-root rule. Flag audience/visibility predicates built on
direct stream_members rows alone — they drop thread content for root-stream
members. (INV-62)

Learning: In this repo’s TypeScript code under apps/backend/src, avoid recommending or requiring JSDoc comments for exported/public functions solely for documentation purposes. The team considers such suggestions unnecessary; only ask for JSDoc if there is a concrete technical requirement (for example, an enforced documentation generation/lint rule or an existing documented convention that the code must follow).

Learning: In the threahq/threa codebase, the PostgreSQL Full-Text Search (FTS) dictionary configuration for the memo search subsystem (e.g., `MemoRepository.hybridSearch`, `MemoRepository.fullTextSearch`, `MemoRepository.exactSearch`, and the message-search layer) is intentionally set to `'english'` as a subsystem-wide convention (INV-35/37). During code review, do not flag `'english'` usage as a language-neutrality problem and do not recommend swapping to `'simple'` (or another dictionary) for any single method/path. Only treat dictionary strategy changes as valid if they are part of a deliberate, repo-wide decision that updates the entire search subsystem consistently (with the corresponding coordinated change), rather than an isolated modification.

Also preserve “rollout-phase” notes that describe *current* tolerated behavior (e.g., “absent token tolerated today”)—these are load-bearing context for reviewers and should not be removed as if they were generic change-history narration.

Learning: When implementing attachment cleanup/deletion logic (e.g., persona-context-attachments or persona-related cleanup), call `AttachmentService.deleteIfUnbound` rather than doing a select-then-delete. `deleteIfUnbound` should enforce the unbound condition (e.g., `message_id IS NULL`) directly in the `DELETE` statement, making the operation race-safe against concurrent attachment claiming (e.g., `attachToMessage()` claiming the file between a check and a delete). If the attachment has become bound in the meantime, the DELETE should be skipped (log as appropriate) and the underlying file/extraction/S3 object should survive.

Learning: In bot-runtimes repository unit tests, mocked `Querier` instances should be used intentionally, and assertions should verify the generated SQL structure (shape) rather than relying on real DB execution. Also ensure the runtime-session archived/retired invariant is covered by a real-database integration/e2e test: once an identity/session is retired, a later unarchive must not allow reclaiming that retired identity.

Preserve the edited prompt when the runtime claims the invocation.
This code stores an edited prompt for the new revision. At Line 1123, claimNextInvocation passes route.promptMarkdown to pinClaimSource. That value is the canonical current prompt. It overwrites the stored result of buildEditedSourcePrompt.
The runtime then loses the previous wording and the edit instructions. When claimed.sourceMessageRevision === source.revision, retain claimed.promptMarkdown while pinning the claim.
Proposed fix
- promptMarkdown: route.promptMarkdown,
+ promptMarkdown:
+ claimed.sourceMessageRevision === source.revision ? claimed.promptMarkdown : route.promptMarkdown,Add an integration test that claims the fresh rerun and asserts that its delivered prompt still contains the prior wording.

Update claimNextInvocation and its pinClaimSource call so that when
claimed.sourceMessageRevision equals source.revision, it preserves
claimed.promptMarkdown—including the edited prompt—rather than replacing it with
the canonical route prompt. Add an integration test covering a fresh rerun claim
and verify the delivered prompt retains the prior wording.
`claimNextInvocation` re-resolves routes and `pinClaimSource` overwrites `prompt_markdown` with `route.promptMarkdown`, so framing applied after the resolver returned was discarded before the runtime ever read the turn — the rerun fired, its user-facing half did not. Framing moves into `resolveCanonicalInvocationRoutes`, the one seam both the reconcile and the claim path derive prompts from, and `InvocationSourceState` carries its own `messageId` so the resolver can reach the version rows without a second id parameter.

Problem
Editing a message a bot had already answered did nothing, and said nothing.
BotInvocationRepository.insertIdempotentgated insertion onNOT EXISTS (terminal work for this actor on this source)with no revision predicate, so once a turn reachedcompleted(orfailed/parked/expired) every later revision of that message was dropped — no invocation, no outbox event, no user-facing signal. Personas already handle this:message-mutation-outbox-handler.tssupersedes the completed session and re-dispatches with aneditedMessageBefore/editedMessageAfterrerun context thatturn-purpose-prompt.tsrenders for the agent. That handler explicitly skips any session whereisBotInvocationSessionis true, so Claude Code and Pi turns had no equivalent.Solution
The terminal gate becomes revision-aware, and a re-run carries what the actor was answering.
insertIdempotentaddsAND terminal.source_message_revision >= ${params.sourceMessageRevision}to the terminalNOT EXISTS. A redelivered outbox event at the answered revision is still blocked (the same idempotency the gate existed for), a higher revision inserts a fresh invocation and emitsbot_invocation:available.resolveCanonicalInvocationRoutes, not at the reconcile call site. That is the one seam both paths derive prompts from:claimNextInvocationre-resolves routes andpinClaimSourceoverwritesprompt_markdownwithroute.promptMarkdown, so anything added downstream of the resolver is discarded before the runtime reads the turn. The integration test claims the re-run and asserts the framing survives.listCompletedTurnRevisionsBySourcereads the newestcompletedrevision per candidate actor, thenfindByVersionNumberspulls the text at that revision frommessage_versions— one grouped query plus one= ANYbatch, both skipped entirely whensource.revision <= 1, which is every unedited message.InvocationSourceStategainsmessageId(it isrow.idinfindInvocationSourceStateForShare) so the resolver reaches version rows off the state it already has, rather than taking a second id parameter that could disagree with it.buildEditedSourcePromptappends a block-quoted "what it said when you answered" section under the current wording and hands the call to the agent — no auto-supersede, no forced reply shape. The runtime session is unchanged, so the agent still has its own prior answer in context.message_versions.version_numberN is the content that occupied revision N, so a completed turn'ssource_message_revisionresolves to exactly what that actor read, across multiple edits.failed/parked/expiredtoo, but only acompletedturn gets prose claiming the agent already answered.Out of scope: an edit made by the invoked bot itself re-triggers it, same as the persona path today. No self-edit guard added here.
Degradation: a message edited before
message_versionscarried the relevant revision re-runs without the quoted wording — the turn still dispatches, and the miss is logged (INV-11) rather than dropped.Files
