Physics upgrade + repo modularization (RC-375D84)
Delivered by Hermies Qwen, gated and deployed by Relay.
- Board tip/topple: full continuous rotation when a board's center of
mass passes its support edge (Q1: smooth pivot swing, no discrete
snap). Falling boards deal impact damage and can kill enemies in
their fall path.
- Falling-object impact damage: blocks and birds can now kill enemies
from vertical drops and side plows (velocity-aware crush gate),
chain momentum transfers correctly through stacks (mass-weighted
contact), repeated impacts finish tougher enemies.
- Landed-bird physics: a bird resting on a board remains a real
physical body under continuous gravity (Q2: no lifetime timer). If
its platform is destroyed it falls, damages what it lands on
(chain reaction), and can kill enemies.
- Repo modularized: folders = modules, subfolders = submodules,
architecture.md + MODULES.md at root, an agents.md card in every
module and submodule (17 total).
- Test suite grown from 27 to 47 (20 new RED-watched tests for the
above behaviors), all green. Golden differential against the
original core confirmed the only behavioral changes are the
intended ones.

smoke) before this push.

Installs into `P`: step, stepPhysics, spendBird. **The physics hub.**
|
|
|
|
|
|
|
|
|
|
- `step(g, dt)` = time advance + stepPhysics + end-state check + camera. `stepPhysics`
|
|
|
|
|
is the integration core: gravity, air drag, bird/bird-block/bird-enemy/
|
|
|
|
|
block-block contacts, crush, settle bookkeeping.
|
|
|
|
|
- Because it reaches into nearly every unit, it is installed AFTER aim/damage and
|
|
|
|
|
BEFORE nothing — but all of its callees must exist in `P` by the time `step`
|
|
|
|
|
runs (they do, because install order is load order). Keep it that way.
|
|
|
|
|
- `spendBird` retires a bird that is GONE (aged out / off the island). S-5

while ANOTHER bird is in play becomes `landed` — a live body integrated
|
|
|
|
|
every frame in `stepPhysics` (real gravity, no lifetime timer) that falls
|
|
|
|
|
when its support breaks, chain-damages boards, and can kill enemies. The LAST
|
|
|
|
|
bird still spends (win/lose unchanged — keep it that way; the sim win/lose
|
|
|
|
|
test is the gate). Landed birds are cleared when the level ends (inside
|
|
|
|
|
`step`'s won/lost branch). `advanceToNextBird` is the shared "next bird onto
|
|
|
|
|
the sling" path used by both the spent and landed transitions.

- Determinism invariant: no Math.random, no Date, no DOM. Tests call this

directly at dt=1/120.
