Gap check this tick fires real warning (20 min > 15) — illustrating the discipline working. **Pattern-summary**: Aaron's corrections this segment composed into (a) running existing tooling rather than recreating it (search-first), (b) discipline must land at discoverable surface (carved-sentence-plus-index → AUTONOMOUS-LOOP.md Step 0), (c) compression discipline (carved sentences = density), (d) TS-over-bash standardization (B-0156 catch-up). | #1366 (TS port) CLEAN auto-merge armed; #1367 (Step 0 carved-compress + lineage prose fix) wait-ci, all-threads-resolved | This tick teaches **the mechanical check works at decision-time when the agent runs it**. Step 0a fired this tick (20-min gap warning) and I responded by writing this shard. The discipline catches the no-op-cadence pattern Aaron has been correcting throughout the session. CADENCE-TRACK: per-tick mechanical-check discipline applied this tick. |
