## A. Expression unify (before-v2)

**Source used**: CDN `before-480/960` are downscales of the smile master `models/model-{id}-smile.jpg` (2048×3072, the same image the afters were generated from). CDN `before-1440` is a *different* render (the `-neutral` master): already closed-mouth, but hair/framing differ slightly (mouth sits ~1% lower). So v2 was built from the smile master: hair/clothes/background match the 480/960 originals and the afters. See `qc/A-expression-audit/cdn-before-960-vs-1440.jpg`.

**Method**: GPT Image 2 (cc.nexcor.ai, `/v1/images/edits` + mask) on a 1024² face crop → aligned back (similarity transform from stable landmarks) → low-frequency color match → composited only inside a feathered mouth + under-eye mask (mediapipe landmarks). Outside the mask, the PNG master is bit-identical to the old image; 480/960 WebP are composited onto the decoded CDN original, so the only outside difference is WebP re-encode noise.

| model | attempts | outside-mask diff | face SSIM vs old | mask area | result |
|---|---|---|---|---|---|
| f01 | 1/5 | PNG master max **0**; v2-960 vs CDN before-960 mean **0.67** (p99 4); v2-480 mean 0.695 | 960 **0.9355** · 480 0.9238 · master 0.9417 | 2.48% | pass |
| m01 | 1/5 | PNG master max **0**; v2-960 vs CDN before-960 mean **0.714** (p99 5); v2-480 mean 0.686 | 960 **0.9193** · 480 0.9184 · master 0.9306 | 2.94% | pass |

Note: v2-1440 has no matching old 1440 of the same render; it is measured against the smile master resized to 1440 (outside mask = WebP noise only).

**Not changed** (expression audit sheets in `qc/A-expression-audit/`):

- **m02**: CDN 上 17 款 after 里 11 款是露齿笑（和旧原图一致），只有 6 款闭嘴（afro-men / bro-flow / curly-top-fade / long-layers-men / man-bun / modern-mullet）。按「多数 after」规则原图已一致，没做 v2。清单说「after 大多平静」与 CDN 实际不符，需 GUCCI 确认。
- **f02**: 30 款 after 里 22 款露齿笑（和原图一致），8 款闭嘴（blunt-bangs / french-bob / high-ponytail / italian-bob / long-bob-lob / long-straight / low-ponytail / sleek-middle-part）。按多数规则没改。注意 topic-bob-or-lob 用的 3 款恰好都是闭嘴款。
- **f04**: 34 款 after 全部是闭嘴浅笑，和原图一致，不改。
- **f03**: 抽查 34 款：闭嘴浅笑，和原图一致，不改。
- **m03**: 抽查 12 款：一致，不改。
- **m04**: 抽查 10 款：一致，不改。
