Chemistry row *Spread* (canon CONCEPT.md § tag grammar): a heated enemy slammed into another (knockback impact >= threshold, not a walking bump) spreads its heat on contact and passes momentum, so chains cascade with decaying force — chemistry feeding chemistry. Authorship-loud feedback stack per canon: ~80ms hitstop (owned by the hand, capped so chain procs can't lock the world; rides on top of freeze/thaw states), the two tag hues meeting at the point of impact (oriented fx, no proc text), and a per-pair audio sting (procedural placeholder, _ph-marked per asset policy). Burster: second enemy type, HEAT-tagged walking bomb (orange base, literal tag mirror) — self-heats ~0.5/s toward threshold, big detonation. Every 4th spawn. Detonations are now symmetric: they damage enemies AND the mech in radius (one grammar on both sides; heat play prices standing close). Grunt scene exports drive both enemy types — no subclass. Smoke gate extended: burster self-heat observed (retry-tolerant), deterministic staged chemistry proc (heated striker slammed into cold neighbor outside weapon range -> proc counter, heat spread). 3/3 green on nh3-dev headless 4.7.1. Known cosmetic: 2 ObjectDB instances reported leaked at exit (constant, exit-order artifact — audio stream alive at quit), not a runtime leak.

## KINETIC+HEAT chemistry proc marker: the two tag hues visibly meet

## at the point of impact (canon feedback stack — the light and the

## sting are the noun; no proc text, ever). Oriented along the impact
|

## axis: KINETIC steel-blue sweeps in from the striker side, HEAT
|
|
## orange flares out the struck side, white core where they touch.
