feat(perception): freeze blind detector gates

@@ -14,6 +14,9 @@ Each gate produces evidence and an explicit GO, PAUSE or BLOCKED result.
 | Native pipeline telemetry | GO for producer/normalizer contract — lifecycle events and JSONL/MQTT sink boundaries exist and an E41 smoke run records real stage accounting. Durable Worker 006 MQTT wiring/deployment remains pending. |
 | Evidence storage | MEASURED — E44 finds 525,471,092 logical bytes, 312,753,179 unique-content bytes and 1.680146× amplification across 14 E30–E40 roots. Exact-content references/deduplication precede any format migration. |
 | Future transfer | PREREGISTERED — E43 freezes same-K1/mount/calibration/firmware, required streams, connected-component split and independent label reveal. Capture and labels do not yet exist. |
+| E31 binding sensitivity | MEASURED — E45 closes accounting for 87/87 accepted correspondences and finds no material monotonic residual association with represented image radius, rig speed or pose age. It does not supply calibration-target truth or outer-fisheye coverage. |
+| Detector Truth Island | PREPARED — E46 freezes 32 references with no prelabels, predictions, scores or candidate identity in the review package. Two independent reviews and adjudication are still required. |
+| Detector candidate comparison | FROZEN BEFORE TRUTH — E47 freezes raw-KB4 and fixed-valid-FOV-fill predictions from the same exact Mask R-CNN checkpoint. No accuracy result or winner exists before the E46 truth seal. |
 | Product interface | DEFERRED — no new windows, page anatomy or design changes are part of this stabilization increment. |
