P6 (source chain in pinned panel):
Required two server-side changes to make the badge actually meaningful:
- Add `profile` field to GameStatePayload schema (server emits it,
client receives it) so multiplayer clients see the room's active
profile metadata, not just the modifier facts.
- Make `ChessEngine.activeProfile` mutable via `setActiveProfile()`
so PredictionManager can sync it from `game.state` snapshots.
Also wire `modifier-profile.updated` through GameClient + Prediction-
Manager so hot-swap broadcasts update the engine's profile field
reactively.
Fix Lobby.handlePlaySolo's resetToFreshGame to forward the selected
profile to the new ChessEngine — otherwise the local engine had
modifier facts (via server reconcile) but no profile metadata,
breaking source-chain attribution and any other profile-aware UI.
P7 (multiplayer propose → approve → both observe updated):
P8 (multiplayer propose → reject → no updated broadcast):
Implemented at the WS-protocol level using two parallel raw sockets
per test (mirrors multiplayer.spec.ts pattern). Critical sequencing:
- Both sockets opened concurrently via Promise.all so opponent is
listening BEFORE host's propose arrives at the server (otherwise
proposal-pending broadcasts to nobody and the test deadlocks).
- Token must travel at the envelope level, not in payload, for the
server's reconnect-by-token path to fire (otherwise hits ROOM_FULL
on the second connection from each player).
- game.move payload uses algebraic notation strings ('a2', 'a3'), not
square indices — the protocol schema only accepts strings.
- Host re-uses original room.create token, opponent re-uses their
join token. Server's reconnectManager treats both as grace-window
reconnects since the original WS closed cleanly.
Verification:
- 1231 unit tests pass (96 files)
- 58/58 Playwright tests pass in 1.9 min (was 55 + 3 fixme)
- Total Playwright surface coverage: solo-smoke (7) + multiplayer (2) +
full-flow (1) + layouts (24) + modifier-profiles (24 — including all
8 T2-polish tests, 0 fixme).
