+## CONTRARIAN GATE — REVISIONS APPLIED (2026-06-29, verdict APPROVE-PLAN)
+The /contrarian plan-gate approved this plan with the following BINDING fixes. They override any conflicting text above.
+
+1. **APCA-over-WebGL (HARD).** Every HUD panel/element at age **65+** MUST have a SOLID 100%-opaque background colour BEFORE the APCA check runs — NO semi-transparent chrome over the live WebGL scene at the senior bands. APCA is measured on the actually-rendered opaque hex pair, not assumed against a static-page background. (Without this the senior gate passes on a tool check but fails visually over the moving 3D scene — the single biggest hole.)
+2. **The age-slider control itself is gated at the elder band.** Its thumb/track/label must clear APCA Lc≥75 + ≥56px hit target + ≥28px label AT AGE 85 — it's persistent on-screen, so it's verified like any senior element in the Phase-5 85-band a11y check.
+3. **Avatar stoop → named `upperRig` sub-group.** The current rig has NO neck group (neck is a direct child of `rig`). Phase 2 build CREATES a named `upperRig` sub-group (torso + neck + shoulders + arms parented to it) so the kyphotic forward-lean at 75/85 is ONE coherent rotation. Invariant preserved: `buildAvatar()` zero-arg == today's age-28 rig byte-for-byte (`upperRig` at 0° rotation = unchanged).
+4. **Bands 21 & 28 differentiated** (were ~80% identical — a 10mm shoulder diff is not a band). 21 Emerging Adult = first-apartment / budget-conscious → energetic, higher-saturation, denser discovery, casual copy, relaxed posture. 28 Young Pro = first real design budget → refined-modern, calmer, spec-forward, professional copy, more upright posture + sharper clothing read. (If still indistinct at build time, MERGE them and add a band at **age 40** to fill the real 35→45 gap.)
+5. **Per-band env tweaks profiled individually.** Any per-band environment change that alters GEOMETRY/LAYOUT (e.g. "extra board spacing" at age 12) is NOT a free scalar — it must be FPS-profiled AT THAT BAND (the Phase-5 FPS≥55 gate runs at EACH band, not just slider-overall). Prefer cheap scalar/colour/light tweaks over layout rebuilds for the age signal.
