AIN-510 Promotion-Ready Local Proof Gate Handoff

The placeholder gates are now real local receipts, the stale vector blocker is resolved, and runtime authority remains deliberately unpromoted.

The Single Idea

AIN-510 now has passing local proof for sensitive mismatch coverage and runtime rollback. A zero-new-vector maintenance run pruned ten orphan/stale vector rows without invoking Gemini, so the gate is promotion-ready locally while public/runtime boundaries remain closed.

01 Status

Proof Gates Pass, Snapshot Is Reconciled

Gate 4 and Gate 5 are no longer placeholders. The sensitive mismatch fixture suite passes with eight local cases, rollback proof passes by reading runtime-readiness and fallback-matrix receipts, and vectors_match_current_chunks now passes after pruning stale rows.

No public runtime, real-user data, external writes, production telemetry, or runtime embedding authority was enabled.
02 What Changed

Two Receipts Became First-Class Proof

Mismatch suiteEight buckets covered with local synthetic exact-vector cases.
Rollback proofReceipt-backed against runtime readiness and fallback matrix outputs.
CLI claritySnapshot failures are printed beside promotion failures.

The patch also fixed token-aware HR detection, prefers distinct source chunks in mismatch cases, and adds negative tests for missing rollback receipts.

05 Claude Review

The First Draft Was Corrected

Claude CLI caught that the first rollback proof was self-validating. The final version now requires existing local runtime and fallback receipts, and tests cover the missing-receipt failure path.

06 Next Slice

Add Controlled Runtime Use

The next move is to add the local runtime authority switch/contract that can consume AIN-510 only when promotion_eligible: true and rollback proof is present. The default authority flag should stay false until deterministic fallback and vector retrieval can be toggled safely.

Where to start

Do not chase new embeddings first. The next runtime gate is controlled internal use with rollback proof and deterministic fallback.
