## Thinking Path
- Paperclip treats issue comments as both communication and wake
signals, so comment attribution affects whether completed work reopens.
- The bug lived in two independent paths: deferred comment wake
promotion in `heartbeat.ts`, and implicit reopen-on-comment logic in
`routes/issues.ts`.
- Both paths need the same core rule: a comment from the same run that
just closed the issue must not look like a fresh human follow-up.
- Deferred wake batches also need one extra safeguard: if a batch mixes
a same-run self-comment with a real human comment, the human follow-up
must still reopen the issue.
## What Changed
- `server/src/services/heartbeat.ts` now suppresses deferred reopen only
when every referenced comment in the batch was created by the closing
run.
- `server/src/routes/issues.ts` now passes `actorRunId`,
`checkoutRunId`, and `executionRunId` into
`shouldImplicitlyMoveCommentedIssueToTodo`, and skips the implicit move
when the comment came from the run that already owns the issue.
- `server/src/__tests__/heartbeat-comment-wake-batching.test.ts` adds
coverage for both Path A cases: same-run self-comment stays closed,
while a mixed self-comment plus human-comment batch still reopens.
- `server/src/__tests__/issue-comment-reopen-routes.test.ts` covers the
same-run guard on both POST and PATCH comment paths, plus the negative
case where a different run still reopens.
## Verification
```bash
pnpm --filter @paperclipai/server exec vitest run src/__tests__/issue-comment-reopen-routes.test.ts
pnpm --filter @paperclipai/server exec vitest run src/__tests__/heartbeat-comment-wake-batching.test.ts -t "self-authored by the closing run|mixes self-authored and human comments"
pnpm --filter @paperclipai/server typecheck
```
## Risks
- Low risk. Both changes are additive guards and preserve existing
behavior for comments that do not originate from the owning run.
- The deferred-wake change now uses all-self semantics, which is the key
correctness detail for mixed batches.
- Full CI is still the authoritative validation for the broader
heartbeat integration surface.
## Model Used
- OpenAI Codex, GPT-5-based coding agent (`codex_local` adapter in
Paperclip).
