Title Coverage Expansion and Runtime Readiness

A restartable map of what changed, where it lives, how it was validated, and what the next agent should do.

The Single Idea

This run converted the completed title map into a production-prep surface: a conservative 248-title local-synthetic expansion queue, a 23-case runtime contract, full validation wiring, tests, semantic sample review, and paired founder/handoff reports. It stayed VDS-local and did not push or merge.

Source Truth

Repo root is /srv/aina/aina-data-engine-room on branch ali/personalization-engine-mission-2026-06-09. The baseline before this milestone was 486a2b4 Add production runtime readiness harness. Primary truth is the live repo plus artifacts/validation/full_validation.json.

artifacts/validation/beta_readiness_path_v1.json
artifacts/validation/icp_title_coverage_v1.json
artifacts/validation/title_coverage_expansion_v1.json
artifacts/validation/production_runtime_readiness_v0.json

Subagent review was advisory. Data-integrity review pushed the overlay to remain local-only; runtime correctness review pushed golden cases by boundary class; semantic/product review pushed the final quarantine for physical/frontline, regulated-domain, software-delivery, vendor-stack, and generic-tail leakage.

What Was Built

src/aina_data_engine/title_coverage_expansion.py is a new receipt generator and CLI surface. It reads source coverage and beta readiness, then writes a candidate overlay without mutating the beta map.

src/aina_data_engine/production_runtime_readiness.py now carries a 23-case runtime contract with categories, edge tags, beta function, seniority, safe claim level, market signals, semantic pass, and BLS grounding.

Surface	Current result
Title expansion candidates	248 local-synthetic candidates, 96 low-signal rows blocked
Runtime contract	23 cases, 17 plans, 6 fallback plans, 2 holds, 4 blocks
Validation wiring	`validate` now checks expansion and runtime summaries
Production unlocks	0 real-user, external-write, telemetry, public-runtime, or production-claim unlocks

Files and Artifacts

Code and tests changed:

src/aina_data_engine/title_coverage_expansion.py
src/aina_data_engine/cli.py
src/aina_data_engine/reports.py
src/aina_data_engine/production_runtime_readiness.py
tests/test_title_coverage_expansion.py
tests/test_production_runtime_readiness.py stayed green against the expanded model

Generated artifacts to preserve:

artifacts/validation/title_coverage_expansion_v1.json and .jsonl
artifacts/reports/title_coverage_expansion_v1.md and .html
artifacts/validation/production_runtime_readiness_v0.json and .jsonl
artifacts/runtime/production_runtime_readiness_v0_golden_cases.jsonl

Validation

Already run and passing:

Focused tests passed 6 passed. Full suite passed 183 passed. Current validation status is pass.

Not Production Yet

This milestone does not make the system production-live. There is no real UI, auth/session/tenant boundary, real learner data handling, production telemetry, external writes, or public runtime. The 248-title overlay is a packet-hardening and runtime-regression queue, not a public allowlist.

Resume Commands

cd /srv/aina/aina-data-engine-room
git status --short
uv run aina-data-engine --root /srv/aina/aina-data-engine-room validate
jq '.title_coverage_expansion_summary, .production_runtime_readiness_summary' artifacts/validation/full_validation.json

Recommended next milestone: rank the 248 candidates, pick a reviewed 25-50-title allowlist, harden packets, expand BLS coverage, and build an internal runtime/API boundary around the 23-case contract.

Where to start
Start from full_validation.json, then inspect title_coverage_expansion_v1.jsonl for the candidate queue.
