PR walkthrough: Open the visual walkthrough

Today: Reassigning a task to the same agent more than 24 hours after the first assignment silently does nothing — no error, no run, no inbox item, no log above Debug. The agent just never wakes up, and there is no trace to explain why.
After this: Every Office dedup key now carries a generation identity that changes with each real occurrence (create, reassign, unassign), so a repeat assignment always queues a real run. Any enqueue that genuinely can't be deduplicated is reported instead of discarded.
Who hits this: Anyone re-assigning a long-lived task or epic to an agent it was already assigned to before — a common retry/rerun pattern once a task has been open more than a day.
Scope: standalone — Office scheduler/dedup only, no other feature slices in flight.
Not here: rate-limiting repeated self-reassignment (this branch intentionally makes a same-agent repeat a real, always-processed occurrence instead of a silent no-op, which removes an existing throttle side-effect; a cooldown is filed as a follow-up), and a pre-existing, unrelated gap where two producers' fallback QueueRun paths don't exempt task_comment keys from coalescing (also filed as a follow-up).

Office's task-assignment dedup key never varied across occurrences, so a durable UNIQUE(idempotency_key) index silently rejected any reassignment more than 24 hours after the first one — the fast 24h-window check passed, the insert failed, and the failure was swallowed as a normal dedup at Debug level. Every persisted dedup key in Office now carries a generation identity that changes with each real occurrence, and any enqueue that can't be safely deduplicated is now counted and logged instead of vanishing.

Important Changes

  • Added tasks.assignment_generation, bumped on task creation and on every reassignment/unassignment, carried (never re-read) into the task_assigned:<task>:<agent>:<generation> dedup key built by one shared key builder.
  • Relaxed the same-agent equality gate in the reactivity pipeline so a same-agent repeat assignment is treated as a real occurrence instead of being silently dropped before it ever reaches the dedup key.
  • Every reactivity/routine/failure-recovery producer that has no durable identity to key on now explicitly reports a "keyless enqueue" (office_run_dedup_total, visible at /debug/vars in dev mode) instead of silently relying on a fallback key that has been removed.
  • QueueOutcome (queued / deduped / coalesced) is now propagated and logged at INFO or above everywhere a dedup decision happens, instead of being swallowed at Debug.

Validation

  • Rebased onto main (branch is now directly on top of 401947fd8); resolved
    real conflicts where an independently-merged fix (fix(office): stop Mark fixed from leaving an auto-paused agent stuck #3464) gave manual resume
    ("Mark fixed") a real dedup key derived from the failed run's id — kept that
    key over this branch's own keyless-by-design choice for the same call site
    (it's strictly better) and dropped the now-superseded test. Also merged a
    webhook explicit-idempotency-key feature into the routine dedup key builder
    (explicit key still wins over the claimed-tick cron identity).
  • go build ./..., go vet ./..., gofmt -l . — clean, whole backend module,
    post-rebase.
  • golangci-lint run ./... --new-from-rev=401947fd8 (current merge-base) — 0
    issues.
  • go test -race ./internal/office/... ./internal/runs/... ./internal/task/service/... ./internal/backendapp/...
    — green except pre-existing failures, reproduced byte-identically against
    the merge-base commit in a scratch worktree (worktree/env-cleanup tests in
    internal/task/service/internal/backendapp, one pre-existing office
    priority-migration fixture gap in internal/office/repository/sqlite
    unrelated to this change's migration).
  • make lint, make lint-format, make test-cli, make test-scripts — clean
    (one pre-existing make test-scripts failure, dev-prod-db-path.test.sh's
    Windows-path-quoting case, reproduced byte-identically at the merge-base).
  • python3 scripts/lint-spec-files.py --all — passed.
  • pnpm run i18n:ratchet — clean; zero apps/web/ files touched by this change.
  • No Playwright E2E: this change has no UI surface (the apps/web/ diff is
    empty). The only observable surfaces are /debug/vars counters and backend
    logs.
  • Full apps/web vitest suite did not finish inside this sandbox's available
    time (two 1800s runs both timed out under severe, unrelated CPU contention —
    load average ~122 on a 14-core box, from other concurrent tasks in this
    multi-tenant sandbox, not this change). Declared environment gap, same
    treatment as the Postgres gap below: this branch's apps/web/ diff is empty,
    so it cannot affect any frontend test outcome, and every individual test file
    flagged as failing under load passed 100% when rerun in isolation.
  • Postgres-specific dedup path not exercised in this environment (no
    KANDEV_TEST_POSTGRES_DSN available); the SQLite path is fully covered.
  • 4 rounds of implementation plus adversarial review (independent
    code-reviewer, security-reviewer, and test-supervisor passes, plus codex
    CLI as a cross-vendor outside voice) — all converged with no remaining
    production-bug residual; one additional regression (a wakeup-adapter error
    no longer matching the sqlite-layer conflict sentinel) surfaced and was
    fixed during the post-rebase gauntlet.

Possible Improvements

Low risk. Two adjacent, out-of-scope gaps surfaced during review were filed as separate follow-up cards rather than expanding this PR: a pre-existing CoalesceRun/task_comment exemption gap, and the absence of a rate limit on repeated self-reassignment (now a legitimate, always-processed occurrence rather than a silent no-op).

Findings

Suggestion (recommended, doesn't block)

  1. Silent generation discard in SetTaskAssignee / SetTaskAssigneeAsAgentapps/backend/internal/office/service/task_assignee.go:41,59

    • Issue: UpdateTaskAssignee now returns (int64, error) — the generation is the dedup-key input for any task_assigned run triggered by this call. Both methods discard it with _. Any event the service publishes after these calls carries no AssignmentGeneration, so queueTaskAssignedRun hits the fellBackToStoredRunner || assignmentGeneration == nil branch and enqueues keyless.
    • Why: Keyless is correct per AC-OFFICE-RUN-DEDUP-003. The handleTaskUpdated comment already documents these as redelivery/defensive callers. The concern is purely the invisible discard — a future reader of SetTaskAssignee has no signal that the return value carries dedup meaning. Inline suggestions posted on both lines.
    • Fix: A one-line comment on each _ discard (see inline suggestions).
  2. Duplicate RunReason* constant blocksinternal/office/scheduler/ and internal/office/service/

    • Issue: RunReason* string constants are defined independently in both packages rather than coming from a shared source (e.g. internal/runs/dedupkeys).
    • Why: The spec documents this as out-of-scope for this PR. Noting it because the duplication creates a silent drift risk if one block is updated without the other.
    • Fix: Consolidate into internal/runs/dedupkeys or a thin runconstants package in a follow-up.

📝 Summary

Summary by CodeRabbit

  • New Features

    • Improved run and wakeup deduplication so repeated events are suppressed reliably while distinct task assignments, routine runs, and escalations are processed separately.
    • Task reassignments now track assignment generations, ensuring reassignment to a previous agent can trigger a new run.
    • Reassigning a task to the same agent no longer interrupts that agent’s active session.
    • Added deduplication outcome and keyless-enqueue metrics for improved operational visibility.
  • Bug Fixes

    • Corrected routine idempotency keys for scheduled and manual triggers.
    • Preserved assignment data during database migrations.

Walkthrough

This change adds generation-aware idempotency keys, explicit queue outcomes, shared deduplication reporting, assignment-generation persistence, and keyless-enqueue telemetry across Office run producers.

Changes

Run deduplication and queue outcomes

Layer / File(s) Summary
Shared deduplication contracts
apps/backend/internal/runs/..., apps/backend/internal/office/service/run.go, apps/backend/internal/office/scheduler/run.go
Queue methods now return explicit outcomes. Shared reporters classify windowed and durable deduplication, keyless enqueues, and non-conflict errors.
Generation-aware assignment flow
apps/backend/internal/task/..., apps/backend/internal/office/dashboard/..., apps/backend/internal/office/service/event_subscribers.go
Tasks persist assignment_generation. The value propagates through task events and dashboard mutations into assignment keys. Same-agent reassignment queues a wake without interrupting the active session.
Producer key derivation
apps/backend/internal/office/routines/..., apps/backend/internal/office/runtime/..., apps/backend/internal/orchestrator/..., apps/backend/internal/office/scheduler/reactivity.go
Routine, agent, blocker, comment, mention, retry, and workflow producers use occurrence-specific keys or report keyless causes.
Migration and regression coverage
apps/backend/internal/office/**/_test.go, apps/backend/internal/task/**/_test.go, apps/backend/internal/runs/**/_test.go, docs/specs/office/...
Tests cover key formats, generation propagation, migration preservation, queue outcomes, durable conflicts, keyless reporting, and producer convergence. Existing queue call sites accept the expanded return signatures.

Greptile Summary

This PR introduces occurrence-specific deduplication identities throughout Office scheduling and makes suppression outcomes observable.

  • Adds and transactionally advances tasks.assignment_generation.
  • Carries assignment generations into shared task-assignment key builders.
  • Reworks routine, blocker, comment, recovery, and agent-spawn dedup identities.
  • Propagates queued, deduplicated, coalesced, and no-op outcomes through Office queue interfaces.
  • Adds expvar counters and elevated structured logging for dedup and keyless decisions.
  • Adds migration, concurrency, producer-audit, and regression coverage.

The implementation is broadly consistent across persistence, event publication, reactivity, and queueing, but the new keyless metric exposes an unbounded-cardinality path for agent-controlled reasons.

Confidence Score: 3/5

The PR is not yet safe to merge because an authorized agent can create unbounded metric cardinality through agent-controlled run reasons, and the explicit repository comment requirement must also be satisfied.

The core generation and dedup flow is internally consistent, but the new telemetry path permanently stores unrestricted agent-controlled reason strings in a process-global map, creating a resource-exhaustion path.

Files Needing Attention: apps/backend/internal/office/runtime/actions.go, apps/backend/internal/runs/service/metrics_vars.go, and changed tests containing review-history comments

Security Review

One security concern was identified: SpawnAgentRun records an unrestricted agent-supplied reason as a permanent metric key, allowing an authorized agent to drive unbounded metric-map growth. The reason should be validated, bounded, or normalized to a finite label set.

Do not dismiss failure inbox entries on a same-agent reassignment.

OnAssigneeChanged dismisses the failed run for oldAgentID. The caller invokes it when prevAssigneeID == newAssigneeID, so it can dismiss the current agent’s agent_run_failed entry. Add the inequality and a regression test.

Proposed fix

+ if prevAssigneeID != "" && prevAssigneeID != newAssigneeID && s.failureNotifier != nil {

Greptile (PR kdlbs#3533) found that SpawnAgentRunInput.Reason reached
office_run_dedup_total / office_run_dedup_keyless_total (expvar.Map,
never evicts) verbatim as a label with no length bound, letting an
agent with CapabilitySpawnAgentRun grow those process-global maps
without limit. Reject an over-length Reason before it reaches either
the run spawner or the metric label.

Also: apply github-actions' suggested comments documenting the
intentional generation-discard in SetTaskAssignee /
SetTaskAssigneeAsAgent, and reconcile the design doc's stale
manual-resume classification (requeueRunForTask picked up a real
generational key from upstream kdlbs#3464 during this branch's rebase,
which Part 2/3 hadn't caught up to).

Fix silent dedup collisions where task_assigned:<task>:<agent> keys
were permanently unique per pair, causing legitimate re-assignments
after 24h to be swallowed at Debug level with no trace.

- Add tasks.assignment_generation, bumped on create and reassignment,
  carried (never re-read) through task events into dedup keys.
- Route task_assigned, blocker-resolution, agent_error, routine
  dispatch, and agent-supplied keys through shared builders in
  internal/runs/dedupkeys so convergent producers derive identical
  keys for the same occurrence.
- Producers that cannot resolve a generation enqueue keyless instead
  of minting a permanently-unique fallback key.
- Report every dedup decision (windowed/durable hit, keyless) through
  shared reporters in internal/runs/service with expvar counters,
  replacing the previously discarded QueueOutcome.

Implements docs/specs/office/requirements/run-dedup-generation.md.
Adds regression tests found missing during the testing pass: a replay
test for the legacy FK-removal migration sequencing hazard (TRAP 23,
previously zero coverage), a test proving task reassignment across
assignment_generation no longer collides with the durable idempotency
index (the reported defect), and coverage for the office/scheduler
blocker-resolution producer's shared digest key (previously untested).

No production code changes; all three gaps were missing tests for
already-correct behavior.
…ty producers

Review round 1 found that removing QueueRunCtx's dangerous default key
fallback exposed 6 of reactivity.go's 8 run reasons (task_comment,
task_mentioned, task_reopened_via_comment, task_unblocked, task_reopened,
task_review_requested) as never having had their own dedup key or
keyless-telemetry logic, since they were silently relying on that removed
fallback the whole time. Adds the spec's exact key shape for the three
comment-carrying reasons and ReportKeylessEnqueue(..., KeylessCauseByDesign)
for the three status-only reasons, plus the test coverage flagged alongside
it: the producer-audit key-format table test, ApplyTaskMutation coverage for
the same-agent-repeat-wake gate and relocated interrupt guard, the office-side
priority-rebuild migration's assignment_generation COALESCE copy expression,
and SpawnAgentRun's caller-run-id key prefix.
reactToStatusChange reported task_unblocked and silent task_reopened
as keyless-by-design before checking whether the task had an assignee.
The queue closure silently drops an empty agent id, so an unassigned
task still incremented office_run_dedup_keyless_total for an enqueue
attempt that never occurred.
AC-002.1 required office/scheduler.cascadeBlockersResolved and
office/service.resolveAndWakeIfUnblocked to derive the same dedup key for
an equivalent blocker set, but no test drove the second producer directly.
Add coverage exercising resolveAndWakeIfUnblocked end to end and asserting
its persisted operation id matches the digest the other producer would
derive for the same occurrence.
Manual resume (Mark fixed / unpause) has no prior occurrence row to key
on and reports itself keyless by design, but no test exercised that call
site. Drive it through the public MarkAgentRunFailedFixed entry point and
assert the counter's exact delta.
cascadeReviewRequested reported ReportKeylessEnqueue once per
workflow_step_participants row, but the queue closure dedupes enqueue
attempts by agent, so an agent seated as both reviewer and approver
was counted twice for one actual enqueue attempt.
…ment

runReactivityForAssigneeChange flipped the prior assignee's office
session row to COMPLETED whenever a previous assignee existed, with no
comparison against the new assignee. A same-agent repeat assignment is
not a handoff (the reactivity pipeline already declines to interrupt
it), so terminating the persisted session row there risked a duplicate
session on the next EnsureSessionForAgent call.
…aths

Existing coverage only asserted the resulting row count on a
redelivered key, so a regression that dropped ReportWindowedDedup from
either office-owned QueueRun implementation would have gone
undetected. Adds an exact-outcome and exact-counter-delta assertion
for both.
Rebasing onto main pulled in an independent fix (kdlbs#3464) that gave manual
resume ("Mark fixed") a real dedup key derived from the failed run's id
instead of the keyless-by-design placeholder this branch had chosen for
the same call site — keep the real key, since it is strictly better, and
drop the now-obsolete test asserting the superseded keyless behavior.

Also merges the routine dedup key builder with a webhook explicit-key
feature that landed independently: an explicit request key still wins
over the claimed-tick cron identity, with a new test pinning that
priority. Fixes the remaining QueueRun call sites broken by its
now-two-value return signature, and wraps both wakeup-conflict sentinels
in routineWakeupAdapter's error so errors.Is still matches the
sqlite-layer ErrWakeupIdempotencyConflict alongside the routines-layer
ErrWakeupAlreadyRequested.

The "prior art" search log recorded a specific local wiki vault path and
config filename from the authoring sandbox. Neither is durable content
the spec needs; generalize the note so it keeps the skipped-step
reasoning without the personal path.

…main

Rebasing onto origin/main (57 commits ahead, including kdlbs#3517's own
CoalesceRun task-scoping and kdlbs#3520's budget-admission test suite)
brought in more test call sites still assuming office/service.QueueRun's
old single-return-value signature. Update them to the two-value
(QueueOutcome, error) signature this branch already widened it to.

Also resolved during the rebase (folded into the replayed feature
commit, not a separate commit here): tasks.go's UpdateTaskAssignee
INSERT picked up upstream's independent created_at column addition to
workflow_step_participants alongside this branch's widened int64
return; run_test.go's TestQueueRun_Coalesce now asserts same-task
coalescing (task_comment became task-scoped like every other reason
under kdlbs#3517, so the old cross-task assertion no longer holds).

Thanks for the contribution. I pushed a scoped fixup commit (44a5ccc9) that keeps the PR direction intact:

  • Task-created events now carry the initial assignee profile ID with the assignment generation, so Office wakes use the durable assignment key and replay remains deduplicated.
  • Agent-supplied metric reasons now use a bounded custom label instead of creating unbounded expvar keys.
  • Reassigning a task to the same agent no longer dismisses that agent's failure inbox entry.
  • I merged the current main branch to resolve the PR conflict.

Focused backend tests and specification lint pass locally. GitHub CI has restarted for the new head.

… allowlist

A rebase onto main pulled in runs/service's metricReason() bounding: any
reason outside its fixed allowlist collapses to "custom" on the
office_run_dedup_total/office_run_dedup_keyless_total labels. The
SpawnAgentRun and routine-wakeup tests used synthetic per-test reason
strings and asserted on them verbatim, so they broke against the merged
behavior. Assert the "custom" bucket instead.

…tracked reassignment

main landed two changes since this branch's last rebase: ADR
2026-09-07-on-demand-document-catalogs removed the tracked specification map
from docs/specs/office/README.md, and kdlbs#3533 threaded an assignment
generation through UpdateTaskAssignee/QueueRun-adjacent reassignment code.
Update the office AGENTS.md's now-stale pointer to the removed README map,
and fix this branch's own tests to match UpdateTaskAssignee's new
(int64, error) signature.

…nd-drop-478

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.

PR kdlbs#3533 (merged to main just ahead of this branch's rebase) changed
QueueRun from returning error to (QueueOutcome, error) but missed 14
test call sites still using the single-value form, breaking go vet
(and therefore golangci-lint and every Backend Tests job) for the
whole module. Update the stale call sites to the two-value form to
unblock this branch's own CI; no behavior change.
