refactor(server): extract name visibility out of GameServer - #5124
Merged
Conversation
Phase 3 of docs/GameServerRefactor.md, second module. Who may see whose real identity — anonymizeNames with host-granted reveals, pinned matchmade teammates, the admin clan-tag reveal in FFA — and what each viewer is shown instead now live in src/server/NameVisibility.ts: - seesReal / seesRealBeyondTeam / anonName, unchanged in logic; - startInfoFor(viewer, isAdmin, real, wire), the per-viewer start message, with the game's own and the wire start infos passed in rather than read off the server; - lobbyClients(viewer, active), the roster projection gameInfo built inline; - friendsLookup(active), used by both the roster and start(). The class reads a small view of the game through thunks (config, the join-ordered client map, teamIndex) so lobby edits and late joins are seen at the moment a payload is built. GameServer constructs one in its constructor; gameInfo is a plain field list again. No behaviour change: the golden wire snapshot is untouched and every gameInfo test passes as-is. Tests: AdminClanTags.test.ts is absorbed into NameVisibility.test.ts, which also covers anonName's stability and team-shared rotation and friendsLookup. The startInfoFor sections of AnonymizeNames.test.ts and AnonymizeNamesTeammates.test.ts drive the module with explicit real/wire inputs instead of poking gameStartInfo into the server.

WalkthroughThe refactor extracts identity visibility and friend lookup logic into ChangesName Visibility Refactor
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The refactor changes name-visibility ownership without changing the wire snapshot, but the added tests bypass the required full-game setup and do not validate the production lifecycle; startInfoFor also relies on aligned real and wire arrays. Merge should wait for the test setup correction and explicit handling or acceptance of that contract. Suggested reviewers: Poem

🤖 Claude Code ReviewVerdict: ✅ No issues found — this is a clean, faithful extraction. Findings by severity: 0 critical, 0 major, 0 minor. No issues found. Checked for bugs and CLAUDE.md compliance. What was reviewed:
Two minor, sub-threshold observations that don't rise to a blocking finding (test-coverage gaps and doc-comment scope are explicitly out of scope per this review's criteria), noted here only for completeness:
|
- Scope the module's header comment: the NameVisibility rules are display-only, but friendsLookup's result is written into gameStartInfo.players[].friends by start() and read by team assignment — which is why it takes no viewer. - Add an end-to-end check that the start message GameServer sends goes through the admin clan-tag reveal: with disableClanTags set, the admin's frame carries real tags in FFA and stripped ones in Team mode, and a regular player's are always stripped. Absorbing AdminClanTags.test.ts into the module test had left this wiring uncovered. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Use the required full-game test setup.
These tests bypass setup() and its map-backed simulation fixture. Move the direct NameVisibility cases and the start-message scenario to setup() so they validate the production game lifecycle.

As per coding guidelines, “Tests use a setup() helper from tests/util/Setup.ts that creates a full game instance with map data from tests/testdata/maps/.”

## Summary Phase 3 of `docs/GameServerRefactor.md`, third of six module extractions (previous: #5114, #5116, #5117, #5122, #5124). A pure move with no behaviour change — the golden wire snapshot is untouched and the turn-loop desync tests pass unmodified. - **`src/server/DesyncDetector.ts`** (new): the hash tally moves verbatim into a pure `findOutOfSyncClients(active, turn)`, and the two sets `GameServer` kept for it — who is out of sync, who has been told — into a `DesyncDetector`. `check(turnsCommitted, active)` returns the tally when a check is due (every ten turns, for the turn ten back, with more than one client); `record(outOfSync)` returns the clients not yet told and marks them. - That split is deliberate: **`handleSynchronization` keeps the schema parse → encode → send → log in the original order**, so the (theoretical) parse-failure path still records nothing, exactly as before. `numDesyncedClients` and the winner / live-stats vote guards read the detector. Net −58 lines in `GameServer`. - **Tests:** the five tally cases move from `GameServerDesync.test.ts` to `DesyncDetector.test.ts` (driven by setting `client.hashes` directly, no sockets), joined by cadence, single-client, record-once and "a check counts nobody" tests. The turn-loop cases (desync frame, count, recorded hash) stay through `GameServer`. `LiveStats.test.ts` marks its out-of-sync client via `desync.record(...)` instead of replacing a private set. ## Test plan - `npx vitest tests/server --run`: 47 files / 487 tests green (was 46 / 481). - Golden snapshot (`GameServerWire.test.ts.snap`): unchanged. - Mutation check: `CHECK_INTERVAL` 10 → 11 fails 3 tests across `DesyncDetector` and `GameServerDesync`; restored. - `tsc --noEmit`, repo-wide `prettier --check .`, oxlint, eslint clean. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Fable 5 <noreply@anthropic.com>

…Server (#5142) ## Summary Phase 3 of `docs/GameServerRefactor.md`, fourth of six module extractions (previous: #5114, #5116, #5117, #5122, #5124, #5126). A pure move with no behaviour change — the golden wire snapshot is untouched. - **`src/server/Consensus.ts`** (new): the two IP-weighted majority votes the game runs over client claims. `WinnerVote` — `cast(msg, ip)` keys the vote (a cancelled match's missing winner as `"null"`), `tally(electorate)` / `tallyAmong(activeIPs)` decide and remember it. `LiveStatsVote` — `cast(clientID, ip, stats, electorate)` takes one vote per client per turn, ignores turns at or before the latest settled one, keeps at most twenty pending rounds, and reports whether the turn settled. - **`GameServer`** keeps what is the game's business, in the original order: the desync / kick guards, `reportedWinner`, the electorate (`votingUniqueIPs`, and the plain active-IP set for the shrink re-tally — preserved as-is), the logging and `archiveGame`. Net −50 lines. - **Tests — the point of this PR:** the last two `archiveGame` spies are gone. `WinnerVoteRetally.test.ts`, the `GameServer` half of `LiveStats.test.ts`, and `ArchivePlayerRecord.test.ts` no longer poke `activeClients` / `allClients` / `gameStartInfo` / `_hasStarted` into the server; they join real clients, start, vote over the wire (or go quiet, or desync via real hash reports) and read the record off the injected `archive`. `Consensus.test.ts` covers both votes directly, including the twenty-round window. Repo-wide `(game as any)` reach-ins 68 → 36 (from ~150 when this series began). ## Test plan - `npx vitest tests/server --run`: 50 files / 509 tests green (was 47 / 487). - Golden snapshot (`GameServerWire.test.ts.snap`): unchanged. - Mutation checks: dropping the live-stats one-vote-per-client guard fails 3 tests; making the shrink re-tally count departed voters (`result` instead of `resultAmong`) fails 2, including the #4136 cheater case. Both restored. - Full `npm test`: 31 failing files / 379 tests — identical to a pristine `origin/main` run (the pre-existing `localStorage` client failures); +12 passing. - `tsc --noEmit`, prettier, oxlint, eslint clean. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-authored-by: Claude Fable 5 <noreply@anthropic.com>

…5143) ## Summary Phase 3 of `docs/GameServerRefactor.md`, fifth of six module extractions (previous: #5114, #5116, #5117, #5122, #5124, #5126, #5142). A pure move with no behaviour change — the golden wire snapshot is untouched and `HostedLobbyListing.test.ts` (1,055 lines) passes unmodified. - **`src/server/ListingState.ts`** (new): a private lobby's presence in the public lobby browser — `listed` / `listedAt` / `label` / `accent` / `featured` — together with the two rules that live on those fields: a repeated listing must not push the auto-start deadline back, and a featured lobby gets the longer deadline. Label sanitisation stays at this boundary, so no unsanitised text can exist on a game. - **`GameServer`** keeps thin public delegates (`isListed`, `setListed`, `autoStartAt`, `isFeatured`, `lobbyLabel`, `lobbyAccent`, `setFeatured`) since Worker, AdminBotRoutes and WorkerLobbyService call them, and `maybeAutoStartListed`, which is lifecycle. Three read sites re-pointed: `updateGameConfig`'s whitelist → delist check, the wire start info's `listed`, and `gameInfo`. Net −31 lines; three imports pruned. - **`tests/server/ListingState.test.ts`** (new, 7 tests): deadline dated from the moment of listing, repeat listing doesn't extend it, delist/relist restarts it, featured deadline, label sanitised at the boundary (control characters stripped, whitespace collapsed; the label renders as text so markup-looking characters are kept), empty label stored as absent. ## Test plan - `npx vitest tests/server --run`: 51 files / 516 tests green (was 50 / 509). - Golden snapshot (`GameServerWire.test.ts.snap`): unchanged. - Mutation check: removing the duplicate-toggle guard in `setListed` fails 2 tests (`ListingState` and `HostedLobbyListing`); restored. - Full `npm test`: 31 failing files / 379 tests — identical to the pristine `origin/main` baseline (the pre-existing `localStorage` client failures); +7 passing. - `tsc --noEmit`, prettier, oxlint, eslint clean. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-authored-by: Claude Fable 5 <noreply@anthropic.com>

A pure move with no behaviour change — the golden wire snapshot is untouched and `MatchTelemetryIntegration.test.ts` passes unmodified. - **`src/server/MatchTelemetryRecorder.ts`** (new): one match's view of the telemetry stream. `emit` builds the envelope (`schemaVersion`, `matchId`, per-match `sequence`, `observedAt`, `serverTick`); a throwing emitter counts as a drop and still consumes a sequence number, so gaps mark drops. `intentObserved` / `takeTickCounts` keep the per-tick counters `turn_committed` reports; `noteArchiveAttempted` and `matchFinished` (once, however many times `end()` runs) cover the end of the match. `identityFor`, which keeps `persistentID` out of telemetry, is an exported function. - **`GameServer`**: four fields and four private methods gone; every emit site passes `turns.length` explicitly where the old `emitTelemetry` default applied. Net −68 lines. - **`tests/server/MatchTelemetryRecorder.test.ts`** (new, 7 tests): envelope/sequence/tick, the sequence gap a drop leaves, per-tick counters split by verdict, zero counts and clearing on take, finished-once with the archive flag, `identityFor` never carrying the persistentID. With this, Phase 3 is complete: six modules in six PRs, golden snapshot unchanged throughout. `GameServer.ts` is 1,944 lines (from 2,365) and test reach-ins are 36 (from ~150), none of them spies on private methods; what remains is lifecycle and ingress state, which Phases 5–6 own. ## Test plan - `npx vitest tests/server --run`: 52 files / 522 tests green (was 51 / 516). - Golden snapshot (`GameServerWire.test.ts.snap`): unchanged. - Mutation check: removing the finished-once guard in `matchFinished` fails 1 test; restored. - Full `npm test`: 31 failing files / 379 tests — identical to the pristine `origin/main` baseline (the pre-existing `localStorage` client failures); +6 passing. - `tsc --noEmit`, prettier, oxlint, eslint clean. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-authored-by: Claude Fable 5 <noreply@anthropic.com>
