`[2026-07-01]` **Persona pane displays the CANONICAL affect→NL Worldtree injects — ADOPT, don't invent (operator steer + reference-impl posture).** Worldtree's `describe_pad` (mood word, valence×arousal grid, ±0.3 bands) + `render_d2_canonical` (relationship directive) are deterministic + canon-driven; the pane now renders them **byte-exact-verified** against Worldtree's own renderer on the live snapshot (v0.19.5, `a99f247`). KEY LESSON: adopting canonical is load-bearing — for sindra's small PAD the canonical says **"neutral"**, but an invented octant vocab would've said "faintly excited" and MISLED. Vendored the two d2 canons (`docs/vendor/worldtree-persona-canon/`) + drift-pinned in `.corviduo-canonicals.toml` (green); flat browser form (`static/persona_render_canon.json`) regenerated via Worldtree's OWN loader (`scripts/build_persona_canon.py`). Vendoring-handshake sent to worldtree-dev (broadcast on canon bumps). [auto-memory: `feedback-ratatoskr-is-a-reference-impl-adopt-canonical`]
