What to do

test/helpers/faultProxy.ts: a TCP/WebSocket proxy between the real Godot client and the real director / world in tests, with knobs — drop client→server, drop server→client, blackhole both (half-open), delay, RST without a close frame — so 001–003’s scenarios also run against the real server, not only the fake Area.
npm run soak (opt-in, minutes): N headless clients walking, portal-hopping, being cut and restored by the proxy; asserts no client ends STALLED / DEAD without a report, positions converge, at most one body per account, presence settles to zero, no zombie peers, no Area shut down under a live peer.
Cover the review’s uncovered list: half-open self-takeover; kicks vs the Godot client; same-tick coalescing; the NOT_HELLO steady state; refcount leaks; director socket dying while playing; world exit with peers attached; control drop / snapshot wedge; portal limbo.
game/README.md: the phone checklist (indicator, report, the exact APK-then-browser repro).

The proxy-backed tests and the soak are green in npm test / npm run soak; the checklist is in the README.
