Tip

PR walkthrough: Open the visual walkthrough

Office's unattended loop — cron tick → trigger claim → routine run → wake → runs row → claim → launch → terminal — had no surface that could say whether it actually ran; on one instance it silently stalled for weeks while every dashboard kept reading healthy. This closes that gap by making every hop of the loop legible: persisted last-fire timestamps, an end-to-end causation id, per-hop counters, a health verdict, and a terminal-shape classification that flags silent successes.

Today: office_routines.last_run_at is never written, there is no way to trace a runs row back to the routine fire that produced it, runs.session_id is silently dropped on launch, and nothing counts or classifies terminal outcomes — a stalled loop and a healthy one look identical from every surface.

After this: every routine fire persists last_run_at monotonically; a causation_id is minted once per wake origin and carried through office_routine_runsagent_wakeup_requestsruns, and runs.session_id is now populated from the real launch session; GET /api/v1/office/workspaces/:wsId/loop-counters exposes per-hop counters without dev mode; GET .../loop-health returns a verdict (unknown → dead → degraded → not_armed → healthy) with evidence and thresholds; and every terminal run gets a derived shape classification over (status, outcome, session_id), including silent_success for a run that claims success with no recorded session.

Who hits this: operators and on-call, through the two new read-only endpoints and the office dashboard. No change to agent-facing or task-facing behavior.

Scope: backend only — internal/office/routines, internal/office/repository/sqlite, internal/office/dashboard, internal/office/service — plus the requirements/system-design pair under docs/specs/office/. Also closes several TOCTOU races on terminal-transition writes surfaced during review: FinishRun/FailRun/CancelRun now report whether their guarded write actually took effect, so a run that loses a race to a concurrent writer no longer double-logs activity, double-broadcasts a cancellation, or double-counts a terminal shape.

Not here: detection only — nothing here fires or re-arms a trigger, requeues a run, or launches an agent, and runs.outcome is not widened. No frontend, E2E, or i18n changes.

Validation

  • go build -tags fts5 ./... — clean
  • go test -tags fts5 ./internal/office/... ./internal/runs/... ./internal/orchestrator/... — all pass except TestMigrate_PriorityIdempotent, confirmed pre-existing on vanilla origin/main via a scratch worktree at the merge-base (unrelated FTS backfill fixture gap, not touched by this branch)
  • golangci-lint run ./... --new-from-rev=<merge-base> — 0 issues
  • go vet ./... — clean
  • make fmt — clean (one pre-existing gofmt-version reformat of canvas_edit_test.go reverted, unrelated to this change)

Review in cubic

nova28 and others added 10 commits September 12, 2026 00:33
Adds the frozen requirements/system-design pair for Office loop
liveness (REQ-OFFICE-LOOP-LIVENESS-001..005) and wires it into the
office spec index.
…and dashboard

Implements REQ-OFFICE-LOOP-LIVENESS-002 through 005.

Correlation (002): persist the requesting wake/trigger's causation_id
onto every run and wakeup request it produces, and have both the routed
and direct launch adapters return the session id an orchestrator launch
actually started so it lands on the run row instead of being discarded.
Production adapters assert TaskStarterWithSession at compile time so a
future adapter cannot silently regress to a session-less launch.

Counters (003): wire the office_loop_* expvar counters (cron tick,
trigger claimed, routine run by disposition, wakeup created, run
claimed, launch, process-started instant) at each counter's persisting
or observing site.

Terminal shapes (005): classify every terminal run transition into a
TerminalShape (launched/silent-success/unlaunched, split by
completed/failed/skipped) and increment office_loop_terminal_total by
shape in transitionRunTerminal.

Dashboard (004): serve GET /workspaces/:wsId/loop-health and
/loop-counters, backed by a first-match-wins verdict precedence
(unknown > dead > degraded > not_armed > healthy) over activation
state, stuck-queued runs, silent successes, and terminal-shape reads.
Any unreadable input fails the whole read with 503 and increments
office_loop_liveness_degraded_total by the failing input's reason
rather than returning a partial verdict.

These four requirements land in one commit because their
implementations are tightly coupled: causation_id minting, counter
increments, and terminal-shape classification live in the same
functions (dispatchRoutineRun, transitionRunTerminal, ClaimNextRun),
and the dashboard reads directly off the terminal-shape and counter
primitives. Splitting them would have meant committing code that
doesn't compile or pass tests on its own — this repo's pre-commit hook
lints the full working tree (staged and untracked together), including
files outside a partial commit's pathspec, so a genuinely passing
partial commit wasn't achievable here.

Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
strftime() is SQLite-only, so /loop-health's stuck-run evidence list
(REQ-OFFICE-LOOP-LIVENESS-004) always 503'd on a Postgres-backed
install. Branch the stuck_since column expression and its Go parse
layout on driver instead: SQLite keeps strftime() + ISO-8601 parsing,
Postgres selects the raw TIMESTAMP column and lets database/sql's
built-in time.Time->string conversion feed the same NullString scan
target. Adds the Postgres-gated regression test this was invisible to.
…uccess activation gap

Review round 1 found office_loop_terminal_total silently missing every
agent-crash (HandleAgentFailure), stale-retry-cancel, and stale-claim-cancel
terminal transition, since only transitionRunTerminal counted shapes and
these three paths bypass it. CancelRun now reports whether it actually
persisted a cancellation, since a no-op on an already-terminal run must not
double-count. ListSilentSuccesses was also missing the activation-instant
floor, letting a pre-activation run misclassify as silent_success.

Also fixes a lost trigger-claim count when a claimed cron trigger's routine
lookup fails afterward, and adds test coverage for the session-persist-
failure counters and the terminal-shape classifier's closed output set,
both called out during review as gaps in the existing suite.
…ancel paths

Testing round 3 found four more production paths writing a terminal run
status (cancelled/failed) without incrementing office_loop_terminal_total,
the same AC-003.1/AC-003.9 violation Review round 1 partially fixed:
failTasklessRun, tree pause/cancel (CancelRunsForTasks), displaced-participant
cancellation (CancelDisplacedParticipantRun), and task-reassignment retry
cancellation (CancelPendingRetriesForTask). Widened the shared
CancelRunsWhere primitive to return the cancelled rows' classification
fields instead of a bare count, threaded that through the bulk-cancel call
sites, and added a TerminalShapeRecorder seam (mirroring the existing
RetryCanceller/TaskCanceller pattern) so the dashboard package's
displaced-run cancellation reaches the same counter without a second,
divergence-prone classification implementation.
CancelRunsWhere read-then-wrote cancellable runs in separate statements,
so a run that finished on another connection between the SELECT and the
UPDATE could be overwritten back to cancelled; it's now one UPDATE ...
RETURNING statement, matching the guard to the write it protects.

transitionRunTerminal pre-fetched the run via the reader handle before
calling FinishRun, so a failed pre-fetch silently dropped the
terminal-shape counter even though the write still persisted; FinishRun
now returns the row via RETURNING so classification never depends on a
second, independently-faultable read.
…review round 3

Guard FinishRun and MarkRunFailed to status = 'claimed' (mirroring
CancelRunsWhere's round-2 fix) so a concurrent cancel can no longer be
silently reverted to finished/failed; callers skip counting, checkout
release, and event publication when the guarded write is a no-op.
Persist launched-session id and the launch counter before the
best-effort resolved-route write, so that write's failure can no
longer abandon a live, uncorrelated agent session. Fix the stranded-
trigger predicate to use the claim instant
COALESCE(last_fired_at, created_at) instead of last_fired_at alone.
Count a routine run immediately after its row is created rather than
after concurrency-policy/materialization succeed, so a persisted run
that later errors is never silently uncounted. Route a zero-rows,
no-error session-id write to the session-persist-failure counter
instead of the without-session counter, in both the routed and direct
launch paths.

Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
R4-1: cancelRetry and cancelStaleRun published OfficeRunProcessed(cancelled)
and (for the latter) an activity log entry even when their guarded CancelRun
write matched zero rows because another writer had already finished or
failed the run — misreporting the run's real terminal state to every
subscriber. Both now return before recording/broadcasting when cancelled
is false, mirroring the existing !wrote pattern elsewhere in this file.

Also closes the test-rigor gaps test-supervisor flagged in Review round 4:
a literal cross-product table for terminal-shape classification, verdict
precedence for unknown-over-dead and degraded-over-not_armed, evidence-list
row content, the loop-health/loop-counters routes' HTTP-level reachability
and 503 behavior, causation_id index partiality, and the heavy routine-fire
path's causation_id/linked_task_id/session correlation chain.

Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Idle-skip and budget-blocked run terminations logged a run_idle_skipped/
run_budget_blocked activity entry unconditionally, discarding FinishRun's
wrote result. A run that another writer already moved out of claimed
still got a false activity entry misreporting why it ended, the same
class of bug already fixed for cancelRetry/cancelStaleRun. Both call
sites now gate the log on the write actually applying.

Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Satisfy errcheck on the causation_id migration helper, gate
finishPolicyBlock's activity log on FinishRun's wrote bool so a lost
terminal-transition race no longer logs a false run_budget_blocked
entry, and remove checkBudget now that admitRun's five-gate system is
the only live caller.

Findings

# Severity Location Summary
1 Suggestion office/service/terminal_shapes.go:14,23,27 and 8 other production files Production comments contain prohibited Review round N, AC-NNN, and BLOCKING FINDING annotations
2 Suggestion office/repository/sqlite/loop_health.go:282 ListTerminalRunsInWindow is unbounded — intentional per spec, but volume ceiling undocumented

Finding 1 — Production comment standard violations

Severity: Suggestion (no functional impact)

CLAUDE.md is explicit: "Production comments state the invariant, not the argument for it: no AC-NN reference, no 'Review round N', no 'BLOCKING FINDING', no narration of a bug's history. That context belongs in the spec, the plan, or the PR body."

The following non-test production Go files introduced or modified by this PR contain violations:

File Lines Prohibited pattern
office/service/terminal_shapes.go 14, 23, 27 AC-005.6, AC-005.4, AC-005.5
office/service/scheduler_runs.go 50, 78, 114 Review round 3, R3-1 × 2; AC-003.8
office/service/failure.go 41 Review round 3, R3-1
office/service/event_subscribers.go 451, 573, 735 Review round 3, R3-1 × 3
office/repository/sqlite/failure.go 276 Review round 3, R3-1
runs/repository/sqlite/runs.go 465 Review round 4, BLOCKING FINDING 2
office/repository/sqlite/loop_health.go 153–157 AC-004.9, AC-004.12, AC-004.5, AC-004.17

The invariants themselves are correctly stated in every case — the fix is to remove the parenthetical (Review round N, RN-N) / (AC-NNN) suffixes. The underlying logic is sound.


Finding 2 — ListTerminalRunsInWindow volume ceiling undocumented

Severity: Suggestion (not a correctness issue)

ListTerminalRunsInWindow (loop_health.go:282) fetches the full set of terminal runs for the workspace in the 24-hour window into Go memory before shape-counting. The docstring correctly documents this as intentional ("Unbounded by officeLoopEvidenceCap: this feeds the terminal-shape counts, not an evidence list"), and the system design backs this up.

However, neither document states an expected maximum row count for a typical or high-volume installation, or describes when a future row cap would be warranted. For a production instance with thousands of daily terminal runs per active workspace, the health endpoint could materialize a large slice on every call. Worth capturing in the system design or a follow-up issue for operators.


Summary

0 blockers. 2 suggestions (comment standards + operational note).

The implementation is architecturally sound. The causation-ID chain, terminal-shape classification, loop health verdict, session-ID persistence, TouchRoutineLastRun monotonicity, wrote bool lost-race guards, workspace-scoped authorization, UNION ALL stuck-run detector, and SQLite/Postgres dialect handling all match the spec. All five prior round-3 blockers (R3-1 through the write-side guards on FinishRun/FailRun/CancelRun/MarkRunFailed) are addressed. Tests cover the key paths. Ready to merge once the comment cleanup is addressed.

Verdict: Ready with suggestions

Greptile Summary

This PR adds end-to-end observability for the unattended Office loop:

  • Persists routine fire recency and causation IDs through routine, wakeup, and run records.
  • Records launched session IDs and classifies terminal run shapes.
  • Adds workspace-scoped loop-counter and loop-health endpoints.
  • Makes terminal writes report whether their guarded transition won concurrent races.
  • One launch-versus-terminal race still produces inconsistent session attribution and terminal classification; the health aggregation is also unbounded.

Confidence Score: 4/5

The PR is not yet safe to merge because a concurrent terminal transition can produce contradictory session attribution and terminal-shape telemetry, and the explicit production-comment requirement must also be satisfied.

Session IDs are persisted only after launch returns, while cancellation can classify the still-claimed run first; the resulting counter and later health classification disagree for the same terminal run. The remaining findings concern bounded health-read cost and repository-required comment cleanup.

Wait until PostgreSQL confirms the lock wait.

time.After(200 * time.Millisecond) does not prove that CancelRunsWhere reached PostgreSQL. If the goroutine starts late, the test commits first and still passes without testing the required lock-wait path.

Use a bounded poll of pg_stat_activity or pg_locks. Continue only after the cancellation connection reports a lock wait.

Reject label segments with multiple = characters.

LoopMetricLabel joins raw pair values, so a repository caller can produce workspace=ws-1;source=x=y. parseLoopCounterKey accepts this value because SplitN(..., 2) returns two parts, and the dashboard routes it as a valid workspace entry instead of placing it in Process.Malformed. Check strings.Count(part, "=") != 1 and add this case to TestReadLoopCounters_MalformedKeyCountsIntoMalformedBucket.

- Line 280: Update failTasklessRun to check wrote before emitting the scheduler
error event, returning without failure-only side effects when another terminal
transition already won. In the test-harness caller, capture the wrote result
from MarkRunFailed and increment failures or pause the agent only when the
transition wrote successfully.

In `@apps/backend/internal/office/repository/sqlite/loop_health.go`:
- Line 287: Update the terminal-run query in the loop health repository to
normalize nullable r.session_id values to an empty string before scanning into
TerminalRunShapeInputRow.SessionID, while preserving the existing alias and
other selected fields.

In `@apps/backend/internal/office/routines/service.go`:
- Line 619: Update materialiseLightweightRoutineRun so a failed
CreateWakeupRequest cannot set disposition to task_created when failed
finalization succeeds; return or propagate the failure disposition explicitly
instead. Add coverage for wakeup creation failure with successful failed-status
finalization, verifying the deferred counter records failure rather than
success.

In `@apps/backend/internal/office/service/budget_admission.go`:
- Line 206: Update the CancelRun and FailRun handling in the relevant service
methods to capture the boolean result from each terminal write. Publish
cancellation events and log cancellation or failure activity only when the write
reports that it applied; preserve error handling for failed writes and avoid
lifecycle evidence when another writer already made the run terminal.
- Line 175: Handle both return values from every FinishRun call: in
apps/backend/internal/office/service/budget_admission.go lines 175-175, capture
err and invoke the existing recovery path before checking wrote; in
apps/backend/internal/office/service/scheduler_integration.go lines 232-232 and
556-556, process terminal-write errors before continuing or returning; and at
lines 255-255, distinguish persistence errors from a lost terminal race.

In `@apps/backend/internal/office/service/event_subscribers.go`:
- Around line 446-454: Ensure terminal-specific side effects in the affected
event handlers occur only after the guarded terminal write succeeds with
wrote=true, including complete/error event emission and routing or output
persistence. Preserve the scoped clearAgentWorking calls on the wrote=false
losing paths, and apply the same ordering to the additional handlers identified
by their terminal write logic.

… on a lost race

Two independent reviewers (greptile, codex) traced the same gap: SetRunSessionID
wrote unconditionally with no claimed-status guard, so a launch that lost a race
against a concurrent cancel could mutate an already-terminal row's session id
after its terminal shape was already classified off the empty one. Guard it to
status = 'claimed', matching every other terminal-adjacent write in this branch.

cancelBudgetRun and cancelUnresolvableAgentRun (budget_admission.go) were also
rebased to widen CancelRun's return to (bool, error) but discarded the new bool
and kept publishing/logging unconditionally, and never called recordTerminalShape
at all -- the same class of bug already fixed everywhere else in this file
(finishPolicyBlock) and package (cancelStaleRun, cancelRetry). Bring both in line.

Also fixes a Postgres-only flake in TestPostgresListStuckRuns: comparing a
nanosecond-precision Go time.Time against a value round-tripped through a
Postgres timestamp column (microsecond precision) fails whenever the source
has non-zero sub-microsecond digits, which macOS-local test runs rarely hit but
Linux CI runners do. Truncate before the round-trip, matching the existing
pattern in workflowsync/azuredevops's Postgres tests.

Round 2 of PR fixup, addressing CodeRabbit's post-push review:

- failTasklessRun appended its scheduler.launch error event before
  checking MarkRunFailed's wrote result, so a run another writer already
  made terminal still picked up a spurious error entry on its timeline.
- materialiseLightweightRoutineRun's wakeup-enqueue failure finalizes the
  run as RoutineRunStatusFailed but returns a nil error, so the caller's
  disposition metric mislabeled a failed dispatch as task_created.
- finishPolicyBlock and three scheduler_integration.go call sites
  discarded FinishRun's error, silently treating a genuine persistence
  failure the same as a benign lost-race no-op.
- handleAgentCompleted and handleTasklessAgentCompleted recorded their
  completion event, routing health, output summary, and continuation
  summary before confirming FinishRun's guarded write actually won,
  letting a lost race attribute another writer's outcome with this
  call's evidence.

Each fix is covered by a RED/GREEN-verified regression test.

…wrote

deferWorkspaceLookupFailure's MaxRetryCount-exhausted branch discarded
FailRun's wrote result and logged run_budget_workspace_lookup_failed
whenever err was nil, even when another writer had already made the run
terminal — the same lost-race gap already closed for cancelBudgetRun and
cancelUnresolvableAgentRun in this file, just in a third function CodeRabbit
named separately (PR fixup round 2, budget_admission.go:418).

Covered by TestDeferWorkspaceLookupFailure_LostRaceDoesNotLog, RED/GREEN

A new repo-wide PR-documentation-coverage check merged into main while this
PR was in flight and requires a linked docs/plans work order for any PR
touching non-exempt paths. This card used the docs/specs spec-driven flow
only; backfill the plan/task-order pair so it resolves cleanly against the
already-frozen requirements and system design.

Re-triggering CI: the E2E Tests run failed to acquire a hosted runner ("Plan external runner allocation" job, not acquired by Runner of type hosted even after multiple attempts"), an infra-side capacity issue unrelated to this branch's changes — several other concurrent PRs hit the same symptom in the same window. Closing/reopening to get a fresh run since I don't have rerun rights on this repo.

Thanks for the contribution. I pushed a follow-up that classifies budget_unmeasurable terminal runs with no session as unlaunched_skipped, adds regression coverage for the terminal-shape matrix, aligns the Office loop-liveness spec, and resolves the merge conflicts. This keeps pricing-degradation skips visible as skipped work instead of unclassified terminal rows.

Resolves a conflict in apps/backend/internal/task/repository/sqlite/task.go
between this branch's preservePosition parameter on updateTaskTx (kanban
reorder's arrival/reorder position-preservation contract) and main's
markerEntryID return value (kdlbs#3533's repeat-task-reassignment fix). Both are
kept: updateTaskTx now takes preservePosition and returns markerEntryID.

Also fixes ~23 call sites across apps/backend/internal/office/service/*_test.go
that still called Service.QueueRun expecting its pre-kdlbs#3613 single-value
(error) return; main's tip commit (bd7974d) changed QueueRun to return
(QueueOutcome, error) without updating every caller, breaking `go vet`/
`go test -c` for the whole package. Confirmed pre-existing and unrelated to
this branch by reproducing byte-identical on a bare origin/main checkout,
whose own CI (Run Backend Tests, run 34749445225) is failing for exactly
this reason. Fixed here only so this branch's own tree compiles and tests
after picking up main.
