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.
Operator ruling 2026-08-07: v1.0 is reserved for the public RC, never
internal milestones. Greybox falsifier recorded as M1 (done, untagged);
M2 pending next-phase decision; parking-lot gate unchanged.
Per canon decisions 2026-08-07 (advisor CONCEPT.md f12cb15, falsifier
response): charges now generate on kills (kills_per_charge, chemistry
chain kills feed the hand; per-hit generation removed). Kills drop
scrap as physical pickups (amber diamond, magnet radius 70, drift to
mech, 20s fade; grunt 1 / burster 3) — collection is the positioning
reward gradient. Cumulative collected scrap gates card levels 1-3
(thresholds 12/30; per-level radius x1.25/x1.5 and power x1.15/x1.5 —
HEAT L3 hits one-cast detonation threshold). HUD: level notches under
slots + scrap counter. Salvage spawn is call_deferred: death can fire
inside a physics signal flush where Area2D setup is blocked.
Smoke gate: charge accrual now kill-fed, salvage drop + collection +
level gating phases added, heat-target selection made retry-tolerant.
4/4 green on nh3-dev headless 4.7.1.
CLAUDE.md carries the convention (smoke-gate command, sidecars ship
with sources, pull-before-editor, git clean recovery); the redundant
Tools section leaves persistent-memory.md per the redundancy rule.
Local pre-commit hook on nh3-dev refuses staged-new .gd without a
tracked .uid (hook is unversioned; recreation documented).
First /snapshot: seeds persistent-memory.md (+ one detail file for the
freeze-meter variant decision), amends CLAUDE.md with the persistent-
memory pointer section.
