+| 2026-05-02T17:16:00Z | opus-4-7 / autonomous-loop session continuation | a2e2cc3a | **Tick-85 PR #1207 opened — operational-enforcement candidate #1 lands.** Implements `tools/hygiene/check-no-op-cadence-pattern.sh` (109 lines bash) per the Tick-80 second-order memo. The script reads last N tick-history shards for the current UTC date, counts minimal-observation-pattern matches via heuristic (body length < 800 OR observation-keyword regex), and prints a WARNING when MIN_OBS_COUNT >= THRESHOLD (default 5). Self-tested both paths before commit: default-threshold-on-recent-shards = 2/7, no warning fires (correct — Tick-80-84 substantive); lowered threshold = warning fires correctly with full body. Configurable via NO_OP_CHECK_WINDOW + NO_OP_CHECK_THRESHOLD. Informational only (exit 0; does not block tick). Closes the architectural loop named in `memory/feedback_recurrence_after_correction_needs_operational_enforcement_otto_2026_05_02.md` — substrate-knowledge alone is insufficient when LLM training prior strongly favors a failure mode; mechanical checks at decision-time produce the corrective. Cron a2e2cc3a still armed. | 2954bd0 (PR #1207) | This tick tests the second-order self-grading discipline. Tick-80 named four operational-enforcement candidates; this tick implements candidate #1 (the only one not requiring human action or substrate-schema-change). Future-Otto: the script exists; wire it into autonomous-loop tick start when the loop infrastructure permits. The remaining candidates (B-0165 Aaron-side deliberate-quiet-periods, B-0164 multi-AI peer review, tick-history schema decision-shape column) compose with this one — operational enforcement IS a substrate-design pattern with multiple instantiations. |
