更迭 · Changelog

A log of what shipped, in the order it happened. Cultural-entertainment project, hand-maintained — not a release manifest. Dates are when the change reached prod; versions are notional milestones, not git tags.

v1.4 (2026-05-17) · Pre-launch hardening

The last engineering session before the 毕业季 banner activates on 2026-05-25.

• Reading caches. 看相 and 合相 now memoize on landmark profile hash (and on the unordered pair, for 合相 — the same two faces in either order resolve to the same reading). Cuts LLM cost for popular inputs without changing what visitors see. 八字 caching shipped earlier; this closes the cache coverage.
• /references attribution. Every reference photo carries an inline photographer credit and CC BY license string at the surface of use — on the result page, beside each match — not buried in a sub-page. The /references index remains the canonical attribution list.
• CI test-gate. The deploy pipeline now runs pytest inside the same multi-arch image it ships, before any SSH happens. A failing test aborts deploy. Adds ~30s to a green run; saves a 5xx outage on a red one.
• Mobile breakpoint. Lookalike result page now fits iPhone SE and Pixel 8 without horizontal scroll.

v1.3 (2026-05-17) · Brand seal + cost dashboard

• 颜值 seal mark. A single-character cinnabar seal replaces the word-mark logo. Same character as the favicon — the brand is the character.
• /tips page. Ko-fi (worldwide, no signup) and WeChat Pay (CN) side by side. The footer "请喝一杯茶" links here.
• CN celebrity pack. 25 curated portraits added to the lookalike reference set under 华语 · Chinese — same CC BY licensing pattern as the Global pack.
• /api/cost dashboard. Internal observability for cache hit ratios and daily LLM spend, gated behind a high-entropy token. Closed by default.

v1.2 (2026-05-16) · Share + consent + quota

• Native share. Every reading result page exposes the OS share sheet (iOS, Android, Chrome desktop) with the rendered card and a short permalink. CN-app fallback for in-app browsers that suppress Web Share.
• Biometric consent. A one-time modal before the first upload of the session explains what reaches the language model (a numerical landmark profile — not the photo) and what doesn't (the photo never leaves memory). Saved locally; no account required.
• Daily quota. Per-feature soft quotas to keep the cost of a single curious visitor bounded. Quota copy points to /tips.
• 八字 cache. First of the reading caches — 4-pillar compute and LLM reading both memoize on (birth_date, gender).

v1.1 (2026-05-14) · Samples + permalinks + 八字 + SEO

• Samples gallery. Public sample readings at stable URLs — a visitor can see the kind of output before they upload anything.
• SQLite permalinks. Result pages get a 24h /r/<slug> link. Permalinks let the share-card screenshot be re-opened by friends.
• 八字 (Four Pillars). Birth-date reading kind alongside the face-based ones. No photo required.
• SEO + legal pages. Per-五行 and per-天干 landing pages, plus /disclaimer · /privacy · /terms · /references. Sitemap covers the durable URLs; ephemeral ones (/r/, /share/, /molemap/) stay out.

v1.0 (2026-05-05) · Public preview

• 看相 (face reading). The classical 麻衣神相 voice, written by a language model from a numerical landmark profile. Chinese-only hero quote ≤14 characters.
• 合相 (compatibility). Two faces, one reading. Order-independent.
• 痣相 (mole map). Per-zone interpretation laid over the face landmarks.
• Live operability. /api/health, cost guards, and the first cut of the operability page.

v0.x (2026-05-04) · Lookalike engine + 颜值 score

• Lookalike. Upload a face, match against a curated reference set, see the closest portraits with an inline distance score.
• 颜值 score. An absolute aesthetic score derived from facial landmarks (symmetry, proportions, harmony), separate from the lookalike distance. Cultural-entertainment scale, not a measurement.
• Reference packs. Initial woman / man Global pack with CC BY licensing maintained per portrait.

v0.0 (2020-04-25) · First commits

The project began as a face-recognition CI/CD scaffold. Most of what runs today was rewritten between 2025-06 and 2026-05; the 2020 commits remain in history as the foundation.
