4819676d84T3 audit gap 2 (CRITICAL). The server's Room kept registered custom
modifier descriptors in a per-room Map but the game.state snapshot
carried no field for them. Impact:
- Client A registers 'custom:shield' → server broadcasts
custom-modifier.registered → A + any currently-connected B see it.
- Client C joins AFTER the registration → receives game.state →
has no knowledge of 'custom:shield'.
- Client C's engine applies a profile with kind='custom:shield' →
registry-dispatch fallback silently no-ops → apparent cosmetic
modifier mismatch between A/B and C.
Symmetric fix across the wire:
- GameStatePayloadSchema (server + client types) gains an optional
customModifiers: CustomModifierDescriptorWire[] field.
- Both emit sites in broadcast.ts (late-joiner path +
reconnect-with-buffered-deltas path) include the room's registered
descriptors.
- PredictionManager.applyFullState mirrors received descriptors
onto the fresh engine's customModifiers registry before handing
control to the UI. Unknown descriptor shapes are accepted as-is
(the wire-shape cast at the single boundary bridges the Zod v3/v4
type split same as the custom-modifier.registered subscriber).
E2E regression guard (Oracle Q4.1 recommendation): new scenario
'late-joiner + reconnect receive registered custom modifiers in
game.state'. Host creates + registers, opponent joins AFTER
registration, asserts opponent's game.state carries the descriptor.
Would have caught the pre-fix behaviour as a test failure instead of
a manual audit find.
1393 unit + 19/19 custom-modifiers e2e green.
