# AIN-510 Retrieval Promotion Gate

Status: `promotion_ready`
Created: `2026-06-13T20:39:31Z`
Model: `gemini-embedding-2`
Dimensions: `768`

## Summary

This gate reads the current Gemini vector snapshot, recomputes exact-cosine
quality pairs, and decides whether embeddings can be promoted as runtime
retrieval authority. It never calls Gemini and it does not promote public
runtime use by itself.

## Snapshot

- Raw vector rows: `6510`
- Valid Gemini vectors: `6510`
- Invalid or non-authoritative rows ignored: `0`
- Vectors matched to current chunks: `6510`
- Stale vector rows: `0`
- Top 1,000 vectors: `1000`
- Top 500 vectors: `500`
- Semantic review vectors: `500`
- Mean vector norm: `1.0`
- Similar/dissimilar cosine gap: `0.190463`

## Snapshot Checks

- PASS `invalid_vector_rows_absent`
- PASS `valid_gemini_vectors_present`
- PASS `vector_snapshot_present`
- PASS `vectors_match_current_chunks`
- PASS `vectors_non_degenerate`

## Sensitive Buckets

- `frontline`: `2235`
- `general_business`: `4407`
- `generic_neighbor`: `2343`
- `healthcare`: `1227`
- `hr`: `3109`

- `regulated`: `5299`

## Promotion Checks

- PASS `gate_1_known_pairs_separate`
- PASS `gate_2_non_degenerate_vectors`
- PASS `gate_2_top_1000_and_500_complete`
- PASS `gate_3_cross_asset_exact_cosine_ready`
- PASS `gate_3_curriculum_vectors_present`
- PASS `gate_3_evaluator_vectors_present`
- PASS `gate_3_workflow_vectors_present`
- PASS `gate_4_sensitive_buckets_present`
- PASS `gate_4_sensitive_mismatch_fixture_suite_present`
- PASS `gate_5_runtime_rollback_proof_present`
- PASS `gate_5_title_to_workflow_curriculum_evaluator_ready`

## Local Proof Receipts

- Sensitive mismatch suite: `pass`
  with `8` cases
- Runtime rollback proof: `pass`

## Runtime Boundary

- Promotion eligible: `True`
- Runtime embedding authority promoted:
  `False`
- Public runtime allowed: `False`
- Real-user data allowed: `False`

## Next Required Proof

Reconcile stale vector rows if any remain; keep the sensitive mismatch fixture suite, runtime rollback proof, and exact-cosine title-to-workflow, title-to-curriculum, and title-to-evaluator comparisons green before runtime promotion is considered.
