AI Fluency Proof-Tail Fixtures

A safe split of the remaining proof/rubric tail into source-backed local fixtures and a repair-first blocked queue.

Ali Mehdi Mukadam · co-authored with Codex · 2026-06-13

The Single Idea

The prior top-band AI Fluency proof tail was not filled with fuzzy title aliases. It was split into safe source-backed local evaluator fixtures and an explicit repair queue, so the engine gets better proof/rubric context without pretending weak metadata is learner proof.

01 · What Changed

A New Exact-Match Supplemental Fixture Lane

Added ai-fluency-proof-tail-fixtures. It reads ai_fluency_top_band_capability_coverage_v1, finds rows that still lack local proof/rubric fixtures, and only creates supplemental fixtures when the row is source-backed, non-generic, and has workflow or named-tool context.

03 · Boundary

It Is Context, Not Learner Proof

This slice did not create learner proof. It created local source-backed evaluator/proof context that can support AI Fluency hardening while keeping measured learner outcome evidence explicitly gapped.

Rows stayed blocked when they were source-less, generic, title-family repair rows, or missing title authority. The remaining 35 rows should be handled by source-ref repair and JD/source-context title resolution, not broad aliases.

AIN-510 remains promotion_ready with 6,506 matched vectors, 0 stale vectors, complete top-500/top-1,000 vector coverage, and runtime embedding authority still false.

Where To Start

Resolve the remaining 35 blocked proof-tail rows by repairing source authority first, then add only source-backed local fixtures that pass the same checks.
