# Clanker Pet — QA / display audit

Findings from live QA of the pet front-end (distinct from the engine's
`v8_audit_log.md`, which tracks VADUGWI scoring issues). The pet is also a
real-world eval harness, so visual/UX defects get logged here with their fix.

## 1. Creature flashes PURPLE on most interactions — FIXED 2026-06-16
**Symptom:** the creature's body briefly turns purple/blue on a lot of messages.
**Root cause:** the M1 "raw read" flash in `applyResponse` (static/app.js) colored
the body with `hue = read.valence / 255 * 360`. That walks the entire hue wheel, so
positive reads (V≈180–255) land at ~254–360° = blue/purple/magenta. It fired on
every message, so he flashed purple constantly. The *settled* mood color was always
fine — the server's `appearance.py` maps valence only across 8°→125° (red→yellow→
green); only the flash used the wrong formula.
**Fix:** the flash now uses `hueForValence()` — the same piecewise red→orange→
yellow→green mapping as `appearance.py`. A low-valence read flashes red/orange, a
high-valence read flashes green. No purple.
