RC-375D84 S-2. Module map: `MODULES.md`; runtime model: `architecture.md`.
|
||
|
|
|
||
|
|
The physics **module** (aggregator). Deterministic, DOM-free.
|
||
|
|
|
||
|
|
- `index.js` is the ONLY public face: it builds the shared scope `P`, runs every
|
||
|
|
submodule installer against it, and exports `ISLE_CORE` (20-key API, see the
|
||
|
|
return literal — keep it key-for-key stable; adding a key is fine, renaming or
|
||
|
|
dropping one is not).
|
||
|
|
- Submodules must load BEFORE this file in the browser (index.html order); under
|
||
|
|
Node this file requires them in dependency order. Do not add a submodule
|
||
|
|
without registering it in BOTH the index.html script list and this file's
|
||
|
|
`require` list.
|
||
|
|
- The core is the simulation's single source of truth: `step(state, dt)` is the
|
||
|
|
only thing that mutates gameplay state. Everything else is either setup
|
||
|
|
(`createGame`), input translation (`launch`), or read-only queries
|
||
|
|
(`activeBird`, `trajectory`, `aimVector`, `starsFor`, `birdsRemaining`).
|
||
|
|
- Invariants: fixed-timestep consumer (tests run 1/120 s); no `Math.random()`
|
||
|
|
in gameplay paths (determinism is a test arm); no DOM access.
|
||
|
|
- New physics behavior lands in the owning submodule, NOT here. RC-375D84
|
||
|
|
S-3..S-5 (landed 2026-09-29): topple/ owns board tip-over (Q1 full continuous
|
||
|
|
rotation), collision/ owns velocity-aware crush + mass-weighted stacks (S-4),
|
||
|
|
step/ owns the landed-bird state and its integration (S-5).
