+| Row | What | Closed | Evidence |
+|---|---|---|---|
+| **R-426** | **The decoy-coverage exemption list — 20 registered gates that ship WITHOUT a decoy test, each named.** (P4) | CLOSED 2026-10-06 — FIXED (the burn-down night): the decoy-coverage exemption list is EMPTY | 20 → 0 in one night: felhom.eu (`68df84bc`, the night/gates commits — hostinstall, due-checks, one-register; three foolable gates fixed), felhom-agent (new `scripts/test_gate_decoys.py`: published against a fake Gitea, release-complete, the shared reuse-refs/instructions/observations), app-catalog (image-pins — three holes closed — image-resolvable, volume-persistence through PATH-stub docker), felhom-controller `7044b11` (docker-v + the three shared scripts). Each decoy red-proved by disabling the gate's check. `scripts/decoy_coverage_gate.py` EXEMPT = {}; the gate prints STALE EXEMPTION if an entry ever outlives its decoy. Decision 135 (one-register). Seen, not changed: image-resolvable reads `no such host` as GONE — a DNS outage would cry wolf. |
