Summary

Add POST /task/:id/redispatch endpoint (auth-gated, M18-8) that reads the original task_history row, checks the Forgejo issue is still open, resolves the agent type, and enqueues a fresh task through the same pool-scheduler path as issues.assigned
Session resume is preserved: if sessions.json still holds a session for <type>:<repo>:<issue>, the new task picks it up
↻ Re-dispatch button in the task detail pane header (failure/cancelled states) and in the task list rows (existing button wired to the real API)
Status codes: 202 queued · 404 unknown id · 409 still running or already succeeded · 410 issue is closed · 503 no agent/token

Changes

forgejo-api.ts: add state field to IssueSummary for closed-issue guard
task-store.ts: add getTaskById() — single-row lookup from SQLite by task id
webhook-handlers.ts: export dispatchIssueForAgent so the re-dispatch handler can reuse the template + pool-dispatch path without duplication
main.ts: handleTaskRedispatch + POST /task/:id/redispatch route
apps/web/src/lib/api.ts: postRedispatch() fetch helper
apps/web/src/components/task-detail.tsx: ↻ Re-dispatch button in top-right actions bar
apps/web/src/routes/monitor.tasks.tsx: wire onRedispatch to call postRedispatch with toast

Test plan

Unit tests in apps/server/src/main.test.ts — 404 (unknown id), 409 (running), 409 (succeeded), 503 (no token for failed row) — all pass (32 pass)
Playwright smoke in apps/web/e2e/monitor.spec.ts — mock failed row, click re-dispatch button, assert POST fires
Manual: cancel a running task, click ↻ Re-dispatch in Monitor → new task id appears in toast, service logs show [redispatch] <old> → <new>

Closes #222

Add POST /task/:id/redispatch endpoint (auth-gated) that reads the
original task_history row from SQLite, checks the linked Forgejo issue
is still open, resolves the agent type, and re-enqueues through the
same pool-scheduler path as an issues.assigned webhook.

- forgejo-api: add state field to IssueSummary for closed-issue guard
- task-store: add getTaskById() lookup by id from SQLite
- webhook-handlers: export dispatchIssueForAgent for re-dispatch reuse
- main: handleTaskRedispatch + POST /task/:id/redispatch route (202/404/409/410/503)
- api.ts: postRedispatch() fetch helper
- task-detail: ↻ Re-dispatch button in top-right actions bar (failure/cancelled)
- monitor.tasks: wire onRedispatch to postRedispatch with toast
- tests: unit tests for the new endpoint + Playwright smoke for re-dispatch button

Review: APPROVED ✅

CI green (run #1871, 6fe9e6a, 4m6s). Full diff reviewed against issue #222 acceptance criteria.

What's correct

Server endpoint (main.ts — handleTaskRedispatch):

Auth-gated via guardMutating (M18-8) ✓
Running-task guard checks both currentTask and the worker queue — covers all live states ✓
SQLite lookup via getTaskById for the authoritative record (not the capped 50-entry in-memory history) ✓
409 for success status correctly blocks re-dispatch ✓
410 for closed issues with actionable error message ✓
503 for missing config / no token ✓
Dispatches through dispatchIssueForAgent — reuses the same pool-scheduler path as issues.assigned, session resume included ✓
SSE broadcast on success (type: "redispatch") ✓
Log line [redispatch] <old> → <new> matches the operator verification step in the test plan ✓

task-store.ts — getTaskById: Clean single-row query; PersistedTaskRow shape contains exactly what the handler needs. ✓

forgejo-api.ts: Adding state? to IssueSummary is the minimal, non-breaking change needed for the closed-issue guard. ✓

webhook-handlers.ts: Only change is exporting dispatchIssueForAgent — correct, avoids duplication. ✓

apps/web/src/lib/api.ts — postRedispatch: Uses encodeURIComponent on the task id ✓. Error-handling matches the rest of the file. ✓

task-detail.tsx: Uses useMutation properly; invalidates ["history"] on success; pending state disables the button. ✓

main.test.ts: 404 (unknown id), 409 (running), 409 (succeeded), 503 (no token) — four paths explicitly exercised. Unit-testing the 202 path requires a live Forgejo/config, which the test environment doesn't have; the test plan correctly routes that to manual verification. ✓

Minor observations (non-blocking)

Toast doesn't link to the new task — issue #222 AC says "a link to the new task detail". The current toast shows ↻ Re-dispatched → task ${short_id} with no clickable link. Given that the selected-task state lives in Zustand (not the URL), a deep-link would require navigating + mutating store state — non-trivial. The history list does refresh immediately via invalidateQueries, so the new task appears at the top of the list anyway. Suggest tracking this as a follow-up UX improvement rather than blocking the merge.

interrupted not in the UI button condition — the issue spec mentions status ∈ {failed, cancelled, interrupted} for the button, but interrupted doesn't exist in PersistTaskInput.status or STATUS_LABEL. Not a real gap.

monitor.tasks.tsx re-dispatch uses raw then/catch (not useMutation) — means the task-list row button has no pending/loading state while the call is in flight. task-detail.tsx does it correctly with useMutation; the list view is a minor inconsistency but not a correctness issue.

All acceptance criteria that can be verified without a live Forgejo instance are met. Core safety rails (409 × 2, 410, 404, 503) and the dispatch path are correct.
