Linear: HEL-3110
Parent: HEL-3103

Summary

  • add the §3.1 minimum event envelope to the existing append-only task_events stream
  • correlate claim, spawn request, process creation/start, heartbeat, and exit by stable work_intent_id
  • enforce replay idempotency with a unique source-event key while leaving current_step_key untouched

Behavioral evidence

  • successful path reconstructs task_claimedworker_spawn_requestedworker_spawnedworker_startedheartbeatworker_exited(completed)
  • failed spawn reconstructs one terminal worker_exited(spawn_failed)
  • duplicate claim and direct source-event replay each produce one logical transition
  • event payload tests reject local-path/raw-text/secret-canary leakage

Tests

  • python -m pytest tests/hermes_cli/test_kanban_db.py tests/hermes_cli/test_kanban_core_functionality.py tests/hermes_cli/test_kanban_db_init.py tests/hermes_cli/test_kanban_work_intent_events.py -q
  • Result: 413 passed, 1 skipped
  • python -m compileall -q hermes_cli/kanban_db.py gateway/kanban_watchers.py tests/hermes_cli/test_kanban_work_intent_events.py
  • git diff --check

Deployment and rollback

  • No production deployment or second telemetry database.
  • Additive SQLite columns/index only. Roll back the commit before release if review rejects the contract.

TRC: HOLD

Exact-head technical review for HEL-3110 at 25fbbaa399b12bc3b8078b2c6980a7e968a4a513.

Disposition: HOLD due to governance race, not a substantive defect in the reviewed change. PR #3 was merged at 2026-07-30T06:24:05Z as merge commit ad29d8dc54a6b98829b17e55b81cd0dd48f2f580 before the required TRC verdict was posted. The task expressly prohibited merge, and the governed merge lane requires a passing exact-head TRC verdict before merge. This review cannot retroactively satisfy that gate.

Substantive evidence at the submitted exact head:

  • Exact identity: remote PR head, submitted SHA, and detached local checkout all matched 25fbbaa399b12bc3b8078b2c6980a7e968a4a513. PR body linked HEL-3110. The PR was open and mergeable at intake.
  • CI: run 30518330237 was green at the exact head, including All required checks pass; no applicable executed check was pending or failing.
  • Independent execution: 414 tests passed with 1 skipped across the four focused Kanban files (179 passed, 1 skipped plus 235 passed). A separate exact-head negative-path subset passed 9/9. Compileall and git diff --check passed.
  • Successful reconstruction: task_claimedworker_spawn_requestedworker_spawnedworker_startedheartbeatworker_exited(completed).
  • Failed reconstruction: failed spawn produced task_claimedworker_spawn_requested → exactly one worker_exited(spawn_failed).
  • Replay/idempotency: replaying the same source transition retained one logical event through the unique idempotency key.
  • Negative paths: claim without spawn remained explicitly incomplete with only task_claimed; stale reclaim produced exactly one terminal worker_exited(stale); stale prior run identity could not heartbeat, block, or complete the newer attempt.
  • Payload minimization: independent probe placed secret-canary, raw-HAA-style text, raw comment text, and an absolute local path in source/task inputs and verified none entered the typed envelopes.
  • Scope: only gateway/kanban_watchers.py, hermes_cli/kanban_db.py, and the focused test file changed. current_step_key remained null/UNKNOWN. No deploy, migration, or production-apply path changed or was executed by this review.

[high] Required pre-merge TRC gate was bypassed → Rhea Ramos / merge-lane owner must record the governance exception or remediate under the governed post-merge process. Do not represent this HOLD as a pre-merge approval. Any further candidate requires a fresh exact-head review.

Re-lands the governed HEL-3110 implementation (originally PR #3, merged
as ad29d8d, reverted by remediation PR #10 / 8684c5b because the
merge bypassed the mandatory pre-merge TRC gate) on post-removal main.

- work_intent_id correlation key on task_events (additive column +
  fresh-schema DDL), work_intent_id = task_id.
- Typed lifecycle events emitted at existing dispatcher mutation
  boundaries in hermes_cli/kanban_db.py: task_claimed,
  worker_spawn_requested, worker_spawned, worker_started, heartbeat,
  worker_exited. gateway/kanban_watchers.py remains caller-only.
- Append-only envelope per HELIOS-THROUGHPUT-TRC-FINAL-SCOPE \u00a73.1;
  idempotency_key dedupe so replaying a source event yields exactly one
  logical transition; no second telemetry DB; current_step_key untouched.
- Payload safety: no secrets, raw HAA text, or local filesystem paths.

Content is the symmetric reverse of PR #10's removal (mechanically the
same lines PR #3 added), rebased over #4/#6 dispatcher changes.

…ion, and backfill gaps

AGA rejection issuecomment-5128947822 reproduced five durable-contract
bypasses at head 3e14c97d4. This commit closes all five behaviorally:

P1 #1 replay safety: persist_review no longer uses INSERT OR REPLACE
(delete+reinsert re-fired the ledger-promotion trigger and nulled
disposition/verification on replay). Both telemetry tables now use true
ON CONFLICT ... DO UPDATE upserts; the findings upsert preserves
MIN(first_observed_at)/MAX(last_observed_at). The promotion trigger
gains a NOT EXISTS replay guard. Regression test replays a
dispositioned+verified telemetry source and proves the full ledger row,
finding-event cardinality, and orphan set are unchanged.

P1 #2 governed attestation: verify_finding only accepts a typed
VerifiedEvidence produced by a governed adapter. fetch_linear_issue_evidence
performs a real Linear GraphQL existence/state lookup (hermetic transport
injection for tests) and binds canonical UUID, observed state, and
verification time; fetch_decision_record_evidence refuses decision refs
never recorded via record_finding_decision. Unknown sources, free-form
strings, mismatched issues, and syntactically-valid-but-nonexistent ids
are rejected with negative tests. The CLI verify path routes through the
same adapters; no free-form evidence flags remain.

P1 #3 bound-field immutability: trg_finding_disposition_bound_immutable
freezes disposition, linear_issue_id, decision_record_ref, and
dispositioned_at once disposition is set; trg_finding_verification_immutable
freezes verified_at, verification_evidence_ref, verification_source, and
verification_observed_state once verified. Direct-SQL tests cover every
bound field; governed FROM-NULL updates still pass.

P1 #4 purge retention: delete_archived_task and delete_task rehome
findings whose telemetry source is retained to the durable rescue
work-intent (finding_rehomed event) instead of orphaning the source;
the rescue container itself cannot be deleted. Tests cover archive-purge
and hard-delete paths with and without retained sources.

P1 #5 migration: init_db DROP+recreates the finding triggers (legacy
boards kept stale narrow bodies under CREATE TRIGGER IF NOT EXISTS),
ALTERs verification_observed_state onto legacy findings tables before
trigger recreation, and idempotently backfills retained
telemetry_review_findings into the ledger - valid tasks promote in
place, absent tasks rehome to the rescue work-intent with a
finding_rehomed event.
