Production Semantic Spine Handoff

A clean local checkpoint for JD-aware role context, AI Fluency maps, Gemini embeddings, retrieval proof, and archive-first donor retirement.

Ali Mehdi Mukadam - co-authored with Codex - repo /srv/aina/aina-data-engine-room

The Single Idea

The repo is much closer to a self-contained local production-readiness data authority candidate, not a public production runtime. The key correction is in the local checkpoint: role context travels with titles instead of trying to repair ambiguous titles in isolation.

02 - Achieved

M0 Through M7 Have Local Proof

MilestoneProof
M0-M1Clean checkpoint, bundle, source authority, and chunk/vector reconciliation.
M2-M4Runtime contracts, JD-aware role context, and AI Fluency headless loop are present.
M5336 contextual chunks have current vectors, 83 repaired generic tool-category chunks and 20 named-tool authority chunks were embedded with 0 failures, and named-tool authority now joins AI Fluency coverage as source context only.
M6AIN-510 is promotion-ready locally, with 6,506 matched vectors and 0 stale vectors.
M7Donor retirement pack exists as archive-first proof; no deletion authorized.
03 - Caveats

What This Does Not Claim

This is not full-corpus vectorization. Current coverage is 6506 / 322515, leaving 316009 chunks unvectorized. Named-tool authority now joins top-band AI Fluency coverage for 121 top-1,000 rows and 59 top-500 rows, but it is still source context, not learner proficiency. promotion_ready is not public production unlock; runtime embedding authority remains false.

Watch-out: do not treat promotion-ready local retrieval as public runtime authority.
Where To Start

Scale only source families whose repair queue and semantic QA pass; keep raw rows and doubtful labels out of embedding authority.
