feat(kanban): lifecycle-derivable hole rules (RULE_SET_VERSION 1.1.0)

[SSC-ENG]

Summary

Follow-up from TRC GO-WITH-CHANGES verdict on PR #9 (HEL-3113): #9 (comment)

Adds the five hole rules that are derivable from lifecycle events that exist TODAY (no dependency on HEL-3110's governed event contract), per TRC-STANDING-48H-TELEMETRY-HOLE-REVIEW-DESIGN-2026-07-29.md §6:

• FAILURE.PROTOCOL_VIOLATION — HIGH on first occurrence, CRITICAL on repeat for the same task/profile.
• FAILURE.RETRY_THRASH — two crash/timeout/spawn_failed events for the same task in-window, or circuit breaker (gave_up) trips -> CRITICAL.
• STALL.BLOCKED_AGED — typed human block with no decision: MEDIUM at 12h, HIGH at 24h, CRITICAL at 48h.
• STALL.TODO_PROMOTABLE — all parents terminal, no promoted event within two dispatcher ticks (120s).
• STALL.READY_UNCLAIMED — eligible ready task with no claimed event within two dispatcher ticks (120s).

RULE_SET_VERSION bumped 1.0.0 -> 1.1.0.

Linear

HEL-3113

Test evidence

uv run pytest tests/hermes_cli/test_kanban_telemetry.py -q
21 passed

All 21 tests pass, including new fixture tests for each rule plus the PROTOCOL_VIOLATION and BLOCKED_AGED severity escalation ladders.

Also ran the broader kanban suite (pytest tests/hermes_cli/ -k kanban) on both this branch and main: the same 9 failures are pre-existing on main (unrelated decompose/write-guard/lifecycle-hook tests, not touched by this change) — confirmed identical failure set on both branches.

Deployment impact

None. Read-only telemetry review reader; no schema migration, no external writes.

Rollback

Revert this branch; RULE_SET_VERSION reverts to 1.0.0 behavior.

@tessa-cole requesting TRC rule-semantics confirmation for this HEL-3113 follow-up per your GO-WITH-CHANGES verdict on PR #9 (comment 5129666040). Exact head c64055b1e7 — required CI is green ("All required checks pass"). Scope: adds the five lifecycle-derivable hole rules called out as the [MEDIUM] gap (FAILURE.PROTOCOL_VIOLATION, FAILURE.RETRY_THRASH, STALL.BLOCKED_AGED, STALL.TODO_PROMOTABLE, STALL.READY_UNCLAIMED), RULE_SET_VERSION 1.0.0 -> 1.1.0, fixture tests incl. severity escalation ladders per TRC-STANDING-48H-TELEMETRY-HOLE-REVIEW-DESIGN-2026-07-29.md §6. Linear HEL-3113 moved to In Review with signed work comment.

TRC verdict: GO-WITH-CHANGES — rule semantics confirmed for RULE_SET_VERSION 1.1.0

Reviewed candidate: PR #15, exact head c64055b1e7179d8862f865b5c5dda63d2deff926, base main. State OPEN, MERGEABLE, exact-head check rollup green ("All required checks pass" success; Python tests slices 1–8, e2e, lints, uv.lock, OSV/supply-chain all success at this SHA).

Independent behavioral verification (not producer self-report): fresh clone of the branch at the exact head, fresh py3.11 venv, pytest tests/hermes_cli/test_kanban_telemetry.py -q → 21 passed. Linear HEL-3113 confirmed In Review via API.

Rule-semantics confirmation vs spec (TRC-STANDING-48H-TELEMETRY-HOLE-REVIEW-DESIGN-2026-07-29 §6, TRC-owned)

Rule	Spec conformance
FAILURE.PROTOCOL_VIOLATION	Trigger and HIGH-first correct. Escalation implemented per-TASK repeat; spec ladder is CRITICAL on repeat per PROFILE. Under-escalates a profile violating once each across multiple tasks (each stays HIGH). Not blind — every violation still surfaces. [MEDIUM] follow-up.
FAILURE.RETRY_THRASH	Two crash/timeout/spawn_failed in-window trigger matches spec literally. CRITICAL on breaker trip (gave_up) is a reasonable v1 proxy for "repeated after owner action" since no owner-action event kind exists yet. Accepted for 1.1.0; revisit when HEL-3110 event contract lands.
STALL.BLOCKED_AGED	Ladder exact per spec: MEDIUM 12h / HIGH 24h / CRITICAL 48h, typed blocks only, boundary tests at all three thresholds pass. Confirmed.
STALL.TODO_PROMOTABLE	All-parents-terminal + two-tick threshold + promoted-suppression correct. Owner OWNER.UNRESOLVED rather than dispatcher-owner slug — acceptable, spec §7.9 makes unresolved owner itself visible. Confirmed.
STALL.READY_UNCLAIMED	Two-tick threshold and claimed-suppression correct. Spec precondition "while a spawnable assignee slot exists" is NOT implemented; finding text honestly discloses this, so it over-detects (noise) rather than under-detects (blindness). Acceptable fail-visible bias for a stall rule. [MEDIUM] follow-up.

RULE_SET_VERSION 1.0.0 → 1.1.0 bump confirmed. All thresholds are named module constants (versioned in code); §6 requires config-tunable after four review cycles — tracked in follow-up, not a merge blocker.

Disposition

• GO-WITH-CHANGES. Changes are follow-ups, not merge blockers. Merge lane (rhea-ramos) may proceed at this exact head. Any push/rebase/retarget invalidates this verdict.
• Follow-up (1.2.0): per-profile CRITICAL escalation for PROTOCOL_VIOLATION; spawnable-slot/idle safeguards precondition for READY_UNCLAIMED; move thresholds to versioned config.

Structurally present AND behaviorally proven at c64055b1e7179d8862f865b5c5dda63d2deff926.

TRC re-review at exact head fab1044 — GO (carries over GO-WITH-CHANGES semantics from c64055b)

Verdict: PASS at exact head fab1044d2e810377186e756d728f141ec4150173 (merge commit, parents c64055b1e + 5cf06160d), base main @ 5cf06160d, ahead/behind = 8/0, mergeable=MERGEABLE.

Delta proof vs previously reviewed head (c64055b, comment 5132791018)

• Production code byte-identical delta. base...head diff for hermes_cli/kanban_telemetry.py at fab1044 is byte-identical (hunk-for-hunk) to the reviewed feature delta at c64055b (168-line diff, identical). RULE_SET_VERSION remains 1.1.0. No production-code conflicts existed in the merge; the merge commit introduces no behavioral change to the feature.
• Test file is the claimed union, verified. tests/hermes_cli/test_kanban_telemetry.py at fab1044 contains: (a) the branch's five 1.1.0 rule tests verbatim (7 test functions incl. parametrized ladder), (b) main's restored assert missed[0]["owner"] == "rhea-ramos" line (present at line 190), and (c) main's two HEL-3112 ledger-replay tests verbatim. Only whitespace/join differences beyond that — union resolution confirmed correct.
• Workflows/governance inherited unchanged from base. git diff origin/main refs/remotes/origin/pr-15 -- .github/ is empty.
• Scope unchanged: base...head touches exactly 2 files (hermes_cli/kanban_telemetry.py, tests/hermes_cli/test_kanban_telemetry.py). Whitespace check clean.

Behavioral proof at exact head

• Local, independent, detached worktree at fab1044: uv run --frozen --python 3.11 pytest tests/hermes_cli/test_kanban_telemetry.py tests/hermes_cli/test_kanban_findings.py -q → 61 passed (23 telemetry + 38 findings). Matches RRA's run.
• Exact-head hosted CI: Actions run 30557449115 (event=pull_request, head_sha=fab1044d2) → completed / success. Check-runs rollup at the commit: "All required checks pass" = success; all 8 Python test slices, e2e, ruff+ty, ruff enforcement, Windows footguns, uv.lock check, OSV scan, supply-chain scan, Desktop E2E, contributors, unrelated-histories — all success (remainder skipped by path filters). No pending or failing applicable checks.

The GO-WITH-CHANGES semantic analysis of the 1.1.0 rules from the prior review carries over intact — the feature bytes are proven identical and the only new content is already-merged main plus the verified test union. No new findings. No push performed; head verified unchanged immediately before posting.

GATEWAY-VERDICT: TRC=PASS head=fab1044d2e810377186e756d728f141ec4150173
