Belt (canon: charges are the cost, the belt is the ammo): cards are CARD_TYPES indices consumed on play, next slides into the 2-slot hand; belt cap 8; HUD shows hand glyphs + upcoming-card ticks. Card pool grows to 4: SHOCKWAVE, HEATWAVE, DASH (impulse along held movement direction — aimable while frozen, no aim input), IGNITE (nearest-enemy heat spike past threshold). Rooms: spawn-budget waves (base 8 +4/room, 4 rooms/run); clear -> interstitial fork (CARD vs SCRAP +8) -> CARD opens a 3-option draft + scrap decline (+4) -> next room; final clear or mech destruction -> tally overlay (rooms/kills/scrap/chem) with relaunch on 1. Interstitial owns the pause while active; the hand yields input and time authority to it. Mech death now signals the run manager instead of hard-reloading. Chain semantics (same-tag surge / cross-tag chemistry trigger) deliberately deferred to M3. Smoke gate: belt consumption white-boxed in the card phase, _until moved to process_frame (physics awaits deadlock under pause), run phase covers clear->fork->draft->belt growth->room advance->tally. 3/3 green on nh3-dev headless 4.7.1.
