AINA Data Engine Room Closeout Engineering Handoff

This is the pause checkpoint for external review. It records what is in the repo, what has been integrated, what remains preserved but not promoted, how the mission/milestones currently map, and the exact boundaries that must survive the next run.

Executive State

The engine room is now a self-contained local data authority for the Personalization Engine path:

source evidence -> source authority -> role context -> AI Fluency capability map -> workflow/practice/evaluator/proof refs -> platform-safe export -> local retrieval proof

The current donor-promotion branch is a direct child of local main, so it can be fast-forwarded into main safely after this report commit. Two sibling audit branches remain intentionally unmerged because they are audit evidence, not promoted authority:

codex/curriculum-release-audit-2026-06-15
codex/source-intelligence-scaleout-audit-2026-06-15

Those branches should be preserved as references until their findings are manually ported or superseded. Do not wholesale merge them.

Repo Shape

Tracked inventory at closeout:

Area	Count
Total tracked files	1,554
`docs/` tracked files	473
`artifacts/reports/` tracked files	376
`artifacts/validation/` tracked files	361
`tests/` tracked files	111
`src/` tracked files	137

Important repo surfaces:

Surface	Purpose
`src/aina_data_engine/`	CLI commands, receipts, table/contract builders, report rendering, validation plumbing.
`tests/`	Focused regression tests for source authority, runtime contracts, donor support gates, embedding eligibility, artifact policy, and validation receipts.
`artifacts/validation/`	Small durable JSON/JSONL receipts that act as the local proof ledger.
`artifacts/reports/`	Human-readable Markdown/HTML companions for validation receipts and gates.
`docs/planning/`	Mission boards, production readiness plan, estate alignment, and next milestone maps.
`docs/handoff/`	Date-stamped closeouts, resume prompts, founder reports, and engineering handoffs.
`docs/learnings/`	Anti-loop learnings, especially clean-before-embed and Vertex/Gemini routing lessons.
`artifacts/embeddings/production/`	Parquet/DuckDB vector/chunk snapshots. Bulk generated data remains ignored unless explicitly selected as a durable receipt.

What Has Been Integrated

The current branch adds the donor-promotion closeout on top of main:

Commit	What landed
`40bd438`	E5 source authority anti-loop receipt.
`ae5703b`	Prior-work promotion delta closure gate.
`ae9688a`	PE alpha feedback support gate.
`59fa329`	PE review packet support gate.
`7bc22aa`	PE industry taxonomy support gate.

The latest promoted donor-support receipts are conservative by design:

Receipt	Result
`pe_donor_review_packet_support_v1`	Counts four 500-row review packets and 2,000 CSV rows, but serializes only packet-level support metadata. Raw packet rows are not promoted to runtime/export/embedding authority.
`pe_donor_industry_taxonomy_support_v1`	Verifies the 17,118-row donor industry taxonomy decision file and records four aggregate decision groups. It does not serialize individual title/category rows or promote row-level labels.
`prior_work_promotion_delta_closure_v1`	Closes the previous donor-promotion delta inventory; generic open count is zero and future lanes are explicit.
`e5_source_authority_reconciliation_v1`	Accounts for nine E5/prior-work assets and confirms no fresh LLM review is allowed where prior reviewed assets already exist.
`source_authority_registry_v2`	Centralizes the current authority map across chunk/vector families and donor support receipts.

Mission And Milestone Map

The current operating mission is:

Make /srv/aina/aina-data-engine-room the self-contained production data/build authority, and have aina-academy or aina-platform consume only versioned, platform-safe exports. Donor repos are read-only quarries. Runtime/public unlocks require explicit release receipts.

Milestone state:

Milestone	Status	Notes
M0 - Durability and board preflight	Mostly complete; this closeout adds final pause proof.	Local archive tags/bundle should be refreshed after this report commit. Remote backup is unavailable in this checkout because no remote is configured.
M1 - Fusion/core reconciliation	Partially complete.	Current donor-promotion branch is safe to fast-forward. Sibling audit branches remain preserved but not integrated. Fusion branches remain evidence, not authority.
M2 - Source authority and export contract	Complete for current scope.	`source_authority_registry_v2` and `engine_room_export_manifest_v1` pass.
M3 - Academy consumer proof	Complete for top 500/top 1,000 local export proof.	Export reads without live VDS DuckDB/Python coupling.
M4 - AI Fluency capability map and role joins	Complete for headless/local proof and top-band coverage.	Learner-observed proof remains future runtime work.
M5 - Clean embedding and retrieval	Substantial but not complete.	151,983 valid vectors are present and AIN-510 passes. Do not broad-scale embed unverified source families.
M6 - Runtime boundary and release receipts	Local-only boundary complete.	Public runtime, real-user data, production telemetry, external writes, and runtime embedding authority remain false.
M7 - Donor retirement and founder pack	Mostly complete.	Retirement pack is ready with no deletion. This report is the external-review pause pack.

What The Engine Can Do Today

Locally, the repo can:

Rebuild and validate the current source-authority registry.
Prove top 500/top 1,000 platform-safe export manifests.
Prove local AI Fluency capability-map fixtures across five layers.
Route top-band title/role/context rows into local runtime payloads with source refs and caveats.
Use exact cosine over current Gemini vector snapshots for local retrieval proof.
Preserve donor repo findings as lineage without mutating donor repos or promoting raw labels.
Show which donor assets are imported, support-only, repair-first, blocked, or deferred.

What The Engine Cannot Claim Yet

The repo should not claim:

Public production runtime is enabled.
Real learner data is processed.
Production telemetry is enabled.
Runtime embedding authority is promoted.
Every source family is embedded.
Raw LinkedIn/JD/company rows are safe to export as-is.
Donor repo branches are fully merged or retired.
Audit branches are product authority.

Branch Integration Plan

Safe action for this closeout:

Commit this report pair on codex/pe-donor-promotion-2026-06-15.
Create archive tags for current main and the donor-promotion closeout head.
Create and verify a full git bundle under /srv/aina/checkpoints/aina-data-engine-room/2026-06-16-closeout/.
Fast-forward main to the donor-promotion closeout commit.
Confirm git diff main codex/pe-donor-promotion-2026-06-15 is empty.

Do not delete branch pointers yet. Do not merge the two sibling audit branches wholesale. Do not mutate donor repos.

Pending Work

Highest-signal next actions after external review:

Manually inspect and decide the two sibling audit branches:
- codex/source-intelligence-scaleout-audit-2026-06-15
- codex/curriculum-release-audit-2026-06-15
Convert the remaining source_intelligence_scaleout_scripts support candidate into a small support/diff receipt if still useful.
Keep using existing validated donor work before doing any title-by-title LLM repair.
Resume embeddings only where source_authority_registry_v2 and engine_room_export_manifest_v1 show product-consumed clean families.
Build the aina-academy integration lane against pinned exports, not live DuckDB or raw VDS internals.
Add a private GitHub remote only if Ali chooses the target; this checkout currently has no remote configured.
