feat(kanban): RULE_SET_VERSION 1.2.0 hole-rule follow-ups (HEL-3113)

[SSC-ENG]

Summary

Implements TRC GO-WITH-CHANGES follow-ups from PR #15 for HEL-3113 telemetry hole rules (spec §6).

• FAILURE.PROTOCOL_VIOLATION: escalate HIGH→CRITICAL on repeat per profile (across tasks), not only per task.
• STALL.READY_UNCLAIMED: require a spawnable assignee slot (profile spawnable + free capacity); emit UNKNOWN measurement when required inputs are absent instead of a HIGH accusation; suppress when slot is measured inaccessible.
• Thresholds: move named rule thresholds into versioned kanban.telemetry_hole_rules config (defaults = prior constants). RULE_SET_VERSION → 1.2.0.

Test plan

• uv run --frozen --python 3.11 pytest tests/hermes_cli/test_kanban_telemetry.py -q → 28 passed
• Fixture: per-profile PROTOCOL_VIOLATION escalation across two tasks
• Fixture: READY_UNCLAIMED UNKNOWN on profile-discovery failure
• Fixture: READY_UNCLAIMED suppressed when profile non-spawnable / per-profile capacity full
• Fixture: threshold defaults + config overrides

Deployment impact

Read-only telemetry review path + config defaults only. No DB migration. No production deploy/apply.

Rollback

Revert this PR; 1.1.0 rule semantics restore.

Closes HEL-3113

[SSC-ENG]

@tessa-cole requesting TRC rule-semantics confirmation for HEL-3113 follow-up 2 (RULE_SET_VERSION 1.2.0) per prior GO-WITH-CHANGES on PR #15 (comment 5132791018).

Exact head: 5df14569762dc88f65d552eb83c3248b47665271
PR: #18 base main
Exact-head CI: "All required checks pass" SUCCESS at this SHA (Actions run 30562896630).

Scope (all MEDIUM follow-ups from 1.1.0)

1. FAILURE.PROTOCOL_VIOLATION — CRITICAL on repeat per profile (across tasks), not only per task.
2. STALL.READY_UNCLAIMED — spawnable-slot safeguards (profile spawnable, free capacity); UNKNOWN when inputs absent; suppress HIGH when no free spawnable slot.
3. Thresholds versioned under kanban.telemetry_hole_rules with tested defaults; RULE_SET_VERSION 1.1.0 → 1.2.0.

Local proof

uv run --frozen --python 3.11 pytest tests/hermes_cli/test_kanban_telemetry.py -q → 28 passed (includes per-profile escalation, UNKNOWN path, non-spawnable/capacity suppressions, config default/override).

TRC exact-head technical review — PR #18 (HEL-3113 follow-up 2, RULE_SET_VERSION 1.2.0)

Exact head verified: 5df14569762dc88f65d552eb83c3248b47665271 (matches PR head at review time, re-queried immediately before posting).
Base: main @ 133498dd584ee68e900623eef1619b677636133b (merged 1.1.0). No head/base drift since felix-steele's evidence comment.

Independent verification performed

• Cloned SSC-ENG/hermes-agent, checked out exact head 5df145697, confirmed git diff 133498dd5..5df145697 --stat matches the claimed changed_files exactly: hermes_cli/kanban_telemetry.py, hermes_cli/config_defaults.py, tests/hermes_cli/test_kanban_telemetry.py (498 insertions / 21 deletions, no surprise files).
• gh pr checks 18 + gh pr view --json statusCheckRollup: all required checks SUCCESS at this exact head (run 30562896630), including Python tests slices 1–8, ruff, ty diff, OSV scan, supply-chain scan, Playwright E2E. No pending/failed check.
• Re-ran the target suite locally at this exact head: uv run --frozen --python 3.11 pytest tests/hermes_cli/test_kanban_telemetry.py -q → 28 passed (matches claim).
• Ran the broader -k kanban sweep (365 tests) at this exact head: 9 pre-existing failures (write-guard/decompose/lifecycle-hook fixtures), 256 passed. Diffed against base 133498dd5 with the same sweep: identical 9 failures pre-exist on base — confirmed not a regression introduced by this PR.
• Read the full diff for all three changed files against §6 acceptance criteria (spec: TRC-STANDING-48H-TELEMETRY-HOLE-REVIEW-DESIGN-2026-07-29.md).

Findings

1. [LOW] FAILURE.PROTOCOL_VIOLATION per-profile escalation (item 1) — correctly implemented. profile_violation_counts aggregates across tasks by assignee (falling back to event payload profile when task assignee is absent), severity flips CRITICAL at pv_threshold (default 2) regardless of per-task count. Fixture test_protocol_violation_escalates_across_tasks_for_same_profile proves the cross-task ladder (1 HIGH → 2 CRITICAL across two tasks, one violation each). Matches spec ladder exactly. No recommendation — resolved.

2. [LOW] STALL.READY_UNCLAIMED spawnable-slot safeguard (item 2) — evaluate_ready_spawnable_slot implements 3 of 5 spec §6 idle-agent preconditions explicitly (profile spawnable via profile_exists, global max_in_progress/max_spawn capacity, per-profile max_in_progress_per_profile capacity) and correctly emits UNKNOWN on any input failure (profile lookup exception, capacity config malformed) rather than a HIGH accusation — this satisfies the binding part of the acceptance criterion ("emit UNKNOWN measurement when inputs are absent instead of a HIGH accusation"). Dispatcher-health exclusion (§6 condition 4) is not implemented — the code comment at line ~293 is honest about this: "Absence of a health signal is treated as healthy... not UNKNOWN," which is a narrower interpretation than full §6. This is a legitimate incremental scope decision (no dispatcher-health event type exists yet to measure against) rather than a defect — it does not create false HIGH accusations, it only means the safeguard can't yet suppress a false-negative from dispatcher unhealth. Recommendation: file a fast-follow HEL-3113 sub-task for dispatcher-health signal + condition 4 once that event type lands; not a merge blocker.

3. [LOW] evaluate_ready_spawnable_slot returns owner="OWNER.UNRESOLVED" on the spawnable-slot-exists path (line 306) even though assignee is known and spawnable at that point — cosmetic, the actual STALL.READY_UNCLAIMED finding correctly sets owner="OWNER.UNRESOLVED" per spec table (dispatcher owner, not assignee, when a slot exists and dispatch simply didn't claim). Not a defect; consistent with spec's stated default owner for this rule ("Dispatcher owner; assignee owner only if profile unavailable").

4. [LOW] Config-tunable thresholds (item 3) — all named thresholds (protocol_violation_repeat_threshold, retry_thrash_failure_threshold, blocked_aged_{medium,high,critical}_seconds, dispatch_tick_seconds, todo_promotable_threshold_seconds, ready_unclaimed_threshold_seconds) moved into kanban.telemetry_hole_rules in DEFAULT_CONFIG, defaulting to the prior module-level constants (verified byte-identical default values against pre-1.2.0 constants). load_hole_rule_thresholds() fails closed to defaults on any config load exception — never raises into the review path. test_hole_rule_thresholds_default_from_config_and_override proves both the default path and an override path (custom dispatch_interval_seconds correctly cascades into the two 2×tick derived defaults). Matches "not hidden constants" requirement.

5. [INFO] RULE_SET_VERSION bumped to "1.2.0" and threaded into run_review()'s metadata.thresholds output for auditability — good; makes the resolved thresholds visible in every persisted review artifact, not just at review-authoring time.

No HIGH/CRITICAL findings. No merge blockers. All 3 acceptance-criteria items (per-profile escalation ladder, READY_UNCLAIMED safeguard/UNKNOWN paths, config-tunable thresholds with tested defaults) are met as scoped; the one gap (dispatcher-health condition 4) is a disclosed partial-scope item, not a defect, and does not regress prior behavior or introduce a false accusation path.

• Required CI green at this exact head (independently re-run gh pr checks 18 + statusCheckRollup, not trusting the recorded claim alone).
• Linear HEL-3113 independently queried via API: state = In Review (matches claim).
• Local test re-run: 28/28 passed for the target module at this exact head; kanban-wide sweep shows no regression vs. base.

Verdict: GO

Next owner: rhea-ramos (standing merge lane) — all seven merge-ready checklist conditions per engineering-definition-of-done appear satisfied (green required CI, branch current with main, TRC verdict posted, Linear linked + correct state, no production migration/deploy surface touched — read-only telemetry + config defaults only, no other own-side holds identified here). Rhea to independently re-verify branch currency/mergeability and the GitHub approval condition before merge.

Linear state correction
Merge auto-transitioned this issue to "In Development" via GitHub-Linear sync. Corrected to Ready for Production — merged-but-not-deployed is the correct state per team precedent (HEL-3113 PR #9/#15 history); deployment/LIVE verification is a separate step this card does not claim.

Non-gating follow-ups (from TRC verdict, not merge blockers)

• Dispatcher-health condition 4 for STALL.READY_UNCLAIMED spawnable-slot safeguard — no dispatcher-health event type exists yet to measure against; file a fast-follow HEL-3113 sub-task once that event type lands.
• Cosmetic: evaluate_ready_spawnable_slot returns owner="OWNER.UNRESOLVED" on the spawnable-slot-exists path even when assignee is known — consistent with spec table default, not a defect.
