Problem

A Steam desktop client that can't obtain a session is rejected from every multiplayer game, and the error names a Turnstile challenge the player never saw.

No ticket → no JWT. Main.ts's getTurnstileToken returns null unconditionally on desktop, so planJoinVerify sees neither a Steam-provider JWT nor a Turnstile token, Worker.ts closes with 1002 "Unauthorized: Turnstile token rejected", and Transport.ts shows that string verbatim. The usual actual fix is restarting Steam.

The rejection itself is correct and stays: the desktop build injects Cloudflare's test site key (a real key is domain-locked and app://openfront can't satisfy one), and isSteamAuthenticated keys on a signed provider="steam" claim rather than the forgeable instanceId. This PR changes where the refusal surfaces and what it says, not whether it happens.

Changes

  • DesktopShell.ts: DesktopSessionState + multiplayerAllowedForSession.
  • Auth.ts: derives a failure reason from the shell's ticket result and the /auth/steam response, published as a desktop-session-state document event (symmetric with the existing desktop-update-state).
  • DesktopUpdateBarDesktopStatusBar, rendering whichever status applies. Session takes precedence over every update state, so the two can't stack in the same slot.
  • Multiplayer entry points gate on either state. Retry re-runs sign-in through the existing authGeneration path, so a success updates the account nav and unlocks the buttons together.

Six failure reasons, each with its own string. steam-wedged — "Steam couldn't verify your session. Restarting Steam usually fixes this." — is the case this exists for.

Two behaviour changes worth review

Every signed-out reason gates multiplayer, including ones the player can't fix. This contradicts the "gate when there is a remedy, not merely when there is a problem" rule documented on multiplayerAllowed just above it. The reasoning: with a pending update, not gating still lets the player play. With no session it doesn't — the server refuses the join either way — so gating is what makes the refusal happen somewhere we can name a cause and offer Retry.

The Steam branch of doRefreshJwt no longer falls through to /auth/refresh. That request can't succeed in the Electron profile (no refresh cookie), so it was a guaranteed 401 that then ran logOut() and dropped the player's persistent ID on every transient Steam failure. It's now terminal.

Depends on a shell change

Needs the matching openfront-desktop change that makes steam:getAuthTicket report why a ticket failed. The two are coupled: a shell built before that change returns a bare string, which this client reads as a failure — so the shell side must land alongside this.

Testing

Rebased onto current main. Full suite green (340 files / 4044 tests) and tsc --noEmit clean after the rebase.

The rebase collided with the trusted-lobby work in GameModeSelector and DetailedGameViewModal. Both sides were kept; re-verified afterwards that all five shouldBlockMultiplayerAction call sites still pass both states and that the trusted-lobby additions survived intact.

The /auth/steam timeout regression test is mutation-verified — removing the AbortSignal makes it hang and fail.

The real wedged-Steam path can't be covered automatically: the join rejection is unreachable on a dev server (ServerEnv.env() !== GameEnv.Dev) and the state needs a live Steam client. Still to be checked by hand.

Walkthrough

The Steam shell now tracks session state, reports authentication failures, supports retry, and gates multiplayer actions. The update bar is renamed to a combined status bar. Steam ticket responses now use typed success and failure results.

Changes

Desktop session authentication

Layer / File(s) Summary
Session contracts and authentication flow
src/client/SteamSDK.ts, src/client/DesktopShell.ts, src/client/Auth.ts, tests/client/Auth.steam.test.ts, tests/SteamSDK.test.ts
Steam ticket results use typed unions. Authentication publishes session states, maps failure reasons, applies timeouts, and supports single-flight retry.
Combined desktop status bar
index.html, resources/lang/en.json, src/client/components/DesktopStatusBar.ts, src/client/Main.ts
The status bar replaces the update bar and renders session or update status. Session retry events restart authentication and refresh the cached profile.
Session-aware multiplayer gating
src/client/GameModeSelector.ts, src/client/components/DetailedGameViewModal.ts, src/client/DesktopShell.ts, tests/*
Multiplayer checks consume session state in addition to update state. Desktop actions are blocked while retrying or signed out. Tests cover session states and renamed element wiring.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 4c042

Failed initial Steam authentication can leave multiplayer controls enabled without a usable session, and a delayed request failure can clear a newer successful retry, producing inconsistent sign-in behavior. The PR also has unresolved multiplayer-entry and stale-dialog edge cases, so it is not merge-ready without fixes or explicit owner acceptance.

Block unknown desktop sessions.

Line 193 allows unknown, although this state means that the initial Steam sign-in attempt is still in flight. GameModeSelector and DetailedGameViewModal use this function to allow multiplayer actions. A player can start a join before authentication settles.

Allow only "signed-in" when state is not null.

@github-project-automation github-project-automation Bot moved this from Triage to Development in OpenFront Release Management Aug 30, 2026
Celant added 3 commits August 30, 2026 21:45
Adds DesktopSessionState and multiplayerAllowedForSession. Unlike the
update rule beside it, every signed-out reason gates -- not gating does
not let the player play, it just moves the refusal to a closing socket
that blames a bot check they never saw.
Auth now derives a DesktopSessionState from the shell's ticket result and
the /auth/steam response, and publishes it as desktop-session-state.

Also makes the Steam branch terminal. It used to fall through to
/auth/refresh, which cannot succeed in the shell -- a guaranteed 401 that
then ran logOut() and dropped the player's persistent ID on every Steam
hiccup.
Renames DesktopUpdateBar to DesktopStatusBar -- one bottom slot, two
kinds of status, so the two can never stack. Session takes precedence
over every update state: the update's remedy is a reload, which leads
straight back to the same wall.

🤖 Claude Code Review

Verdict: Solid, well-tested feature — one real cross-repo contract gap that can break Steam sign-in for players on an older desktop shell build, plus a related state-machine gap it can trigger. Findings: 2 (both High).

src/client/SteamSDK.ts / src/client/Auth.ts

1. (High) getTicket() trusts the native Electron bridge's return shape unvalidated — an old shell build breaks Steam sign-in entirelysrc/client/SteamSDK.ts:37 (return await bridge.getAuthTicket();) and src/client/Auth.ts:113 (if (result.ok))

This PR changes the SteamBridge.getAuthTicket() contract from Promise<string | null> to Promise<SteamTicketResult> ({ok:true,ticket} | {ok:false,reason}). The bridge implementation lives in a separate repository (openfront-desktop), per the PR's own comment: "Mirrors SteamTicketResult in openfront-desktop's src/main/steam.ts. The two repositories cannot import from each other, so this is a hand-kept copy." getTicket() forwards the bridge's result with no runtime shape check, and doRefreshJwt() immediately reads result.ok.

This client ships instantly via CDN on merge, while the Electron/Steam shell updates on Steam's own release schedule — a lag this codebase already treats as the normal case elsewhere (DesktopShell.ts's desktopUpdate()/"blocked" status exists specifically so "a client newer than its shell... must degrade rather than break"). The new Steam code doesn't follow that convention:

  • If an old shell still resolves a raw ticket string on success, result.ok is undefined → falsy → treated as a failure even though sign-in actually succeeded, and since this PR makes the Steam branch terminal (no fallthrough), the player is now gated out of multiplayer with a misleading message until the shell itself updates.
  • If an old shell resolves null (its old "Steam unavailable" signal), result.ok throws a TypeError, propagating uncaught (see finding 2).

Suggested fix: normalize legacy shapes in getTicket() before returning, e.g. typeof raw === "string" ? {ok:true, ticket:raw} : raw && typeof raw === "object" && "ok" in raw ? raw : {ok:false, reason:"unavailable"}.

2. (High) retrySteamSignIn() can leave the session permanently stuck at "retrying" with no recovery pathsrc/client/Auth.ts:209-224 (retrySteamSignIn), interacting with unchanged refreshJwt()/userAuth() (src/client/Auth.ts:220-230, 153-218 on main)

retrySteamSignIn() sets {status:"retrying"} and then awaits userAuth(), relying entirely on some downstream branch of doRefreshJwt() to call setSessionState(...) again before returning. But refreshJwt() only wraps its await in try { } finally { } (no catch), so any exception thrown inside doRefreshJwt() — such as the TypeError from finding 1 — propagates up to userAuth()'s top-level catch, which just logs and returns false without touching session state. retrySteamSignIn()'s own finally only clears the single-flight promise, not the session state.

Since multiplayerAllowedForSession gates multiplayer for "retrying" and DesktopStatusBar.sessionAction() renders no Retry button for that status, a player who hits this path is locked out of multiplayer showing "Signing in…" indefinitely, with no in-app way to retry — only a full app restart recovers. clearLocalSession()'s new guard (skipping session-state updates while status === "retrying") means no other caller can rescue it either.

Suggested fix: in retrySteamSignIn()'s finally, force a terminal state if the status is still "retrying" when the promise settles (e.g. fall back to {status:"signed-out", reason:"steam-error"}), so the guarantee doesn't depend on every downstream branch remembering to publish.

Either a pending update or a missing session now blocks a multiplayer
entry point, so a Steam client that cannot sign in is refused at the
menu -- where the bar can name a cause -- rather than by a closing socket
that blames a Turnstile challenge the player never saw.
Routes it through the same userMe/authGeneration path the CrazyGames
auth listener uses, so a successful retry unlocks the multiplayer
buttons and updates the account nav in one pass.
getTicket() now resolves SteamTicketResult, not string | null. Updates
the bridge-rejects case to assert { ok: false, reason: "error" } instead
of null, and the success case to assert the { ok: true, ticket } shape
the bridge actually returns, so the mock matches the real contract.

Follow-up to 7ba9070 -- tests/SteamSDK.test.ts was outside that task's
listed file set but within its blast radius.
…earLocalSession

doSteamLogin's /auth/steam fetch had no AbortSignal, so a response that never
settles left retrySteamSignIn's state pinned at "retrying" forever -- gating
multiplayer with a bar that renders no button for that state, and pinning
__refreshPromise for later callers. Bound it with AbortSignal.timeout(10s);
the existing catch already maps an abort to reason "network".

clearLocalSession() also left __sessionState at "signed-in" after any
401-triggered logOut(), unlocking multiplayer with no JWT behind it until the
next join self-healed it. Publish a signed-out state (reason "steam-error",
the one SessionFailureKind that names no specific cause) guarded to Steam
only, and skip the publish while a retry is legitimately in flight so it
can't clobber retrySteamSignIn's own transition.

Also updates AuthLogoutAnnounce.test.ts's stale getTicket mock to the current
{ok,reason} shape (dead code there, but was contradicting the real type).

Claude-Session: https://claude.ai/code/session_01M9qvcSpHpT6hg4x5fAAXm2
The existing "settles rather than sticking at retrying when the fetch
rejects" test used mockRejectedValue, which only exercises the pre-existing
catch block and passes identically whether or not the fetch call passes an
AbortSignal. It never proved a hung fetch actually aborts and settles --
the real bug the AbortSignal.timeout(10_000) fix addresses.

Replace it with a signal-aware mock fetch that never settles on its own and
only rejects when the AbortSignal it receives actually fires, driven by
fake timers advanced past the 10s deadline. Verified by temporarily
removing the signal from doSteamLogin's fetch call: the new test hangs and
times out against the unfixed code, and passes once the signal is restored.

handleJoinLobby() accepts join-lobby events from deep-link and matchmaking paths without checking multiplayerAllowedForSession(). If the desktop session remains signed out, getPlayToken() falls back to the persistent ID, which the production server rejects and closes. Add the gate at this boundary for multiplayer events, while preserving local single-player and replay flows.

Advance authGeneration before starting a Steam retry.

When desktop-session-retry overlaps an existing getUserMe() request, invalidateUserMe() leaves the old promise running. retrySteamSignIn() can establish a different session, but the listener captures the unchanged generation. The old response can therefore pass applyUserMe() and overwrite the new account state. Increment authGeneration before capturing generation.

The SteamTicketResult type is explicitly documented as "a hand-kept copy" mirroring a type in the separate openfront-desktop repo, and DesktopShell.ts elsewhere states that "a client newer than its shell is an ordinary situation and must degrade rather than break" — i.e., shell/client version skew is a known, expected condition in this codebase, not a hypothetical.

If an older/mismatched desktop shell still returns the pre-PR shape (a bare ticket string or null) instead of {ok, ...}, then in Auth.ts, result.ok is undefined (falsy), so the new terminal Steam branch runs (no fallback to /auth/refresh), discarding what may be a perfectly valid ticket. Worse, ticketReason(result) (Auth.ts:321-332) switches on result.reason, which is also undefined, and the switch has no default case — so the function returns undefined at runtime despite its declared non-optional SessionFailureKind return type. The session ends up {status: "signed-out", reason: undefined}, multiplayer is gated, and the player sees a generic "couldn't sign in" message with no way to recover (retry re-runs the same broken path).

Net effect: a Steam install that worked fine before this PR can become permanently locked out of multiplayer — strictly worse than the cryptic Turnstile error this PR sets out to replace.

Suggested fix: Normalize the bridge's return value in getTicket() before trusting its shape, e.g. typeof result === "string" ? {ok: true, ticket: result} : result === null ? {ok: false, reason: "unavailable"} : result, and add a default (or otherwise handle the undefined case) in ticketReason() so a shape mismatch fails safe instead of silently violating its return type.


src/client/Auth.ts — High

[High] src/client/Auth.ts#L168-L170 (inside clearLocalSession()):

if (steamSDK.isOnSteam() && __sessionState.status !== "retrying") {
  setSessionState({ status: "signed-out", reason: "steam-error" });
}

clearLocalSession() runs inside logOut()'s finally block, and logOut() is invoked on any 401 from /users/@me (see getUserMe() in src/client/Api.ts) or on an iss/aud claim mismatch in userAuth() — situations that can occur for reasons entirely unrelated to a Steam sign-in failure (e.g. server-side session revocation, key rotation, or a transient auth-service 401). Pre-PR, this self-healed silently: the next userAuth() call would see __jwt === null, mint a fresh Steam ticket, and re-exchange it with no visible interruption.

Post-PR, this same codepath now sets signed-out/steam-error, which multiplayerAllowedForSession gates on, blocking every multiplayer entry point and showing "Couldn't sign in to your OpenFront account" — even though nothing about Steam sign-in actually failed. Nothing automatically clears this state; recovery requires the player to notice and click the Retry button (per the PR's own comment, "There is no automatic retry anywhere"). This turns a previously invisible, self-healing auth refresh into a hard, misleadingly-labeled lockout.

Suggested fix: Don't unconditionally set signed-out/steam-error from clearLocalSession(). Either reset to "unknown" (letting the next userAuth() re-establish the real state) or drive an actual re-exchange, rather than asserting a Steam-specific failure that may not have occurred.


src/client/SteamSDK.ts — Medium

[Medium] src/client/SteamSDK.ts#L33-L42: getTicket() awaits bridge.getAuthTicket() with no timeout:

async getTicket(): Promise<SteamTicketResult> {
  ...
  try {
    return await bridge.getAuthTicket();
  } catch { ... }
}

The PR adds a 10s AbortSignal.timeout to the /auth/steam fetch in doSteamLogin() specifically because a hang would otherwise leave the session pinned at "retrying" forever — a state that gates multiplayer (multiplayerAllowedForSession) and for which the status bar renders no action button (sessionAction() returns nothing for "retrying"). But the step immediately before that fetch, the Electron IPC call bridge.getAuthTicket(), has no equivalent bound. If that IPC call hangs rather than resolving/rejecting, doRefreshJwt() stays suspended indefinitely, state remains stuck at "retrying", multiplayer stays gated, and there's no Retry button — an unrecoverable dead end short of an app restart. This is the same class of risk the codebase already defends against elsewhere: desktopVersion() in DesktopShell.ts races desktop.version() against a 500ms timeout specifically because the bridge is implemented in a separate private repo and "this public repo cannot enforce that its version() call ever settles."

Suggested fix: Race getTicket() against a timeout (mirroring desktopVersion()'s pattern) and map a timeout to {ok: false, reason: "timeout"} so a hung IPC call can't leave the session stuck at "retrying" with no way out.


src/client/Auth.ts — Low

[Low] src/client/Auth.ts#L385-L393 (inside doSteamLogin()):

setSessionState({
  status: "signed-out",
  reason:
    response.status === 401
      ? "steam-ticket-rejected"
      : response.status >= 500
        ? "steam-backend"
        : "network",
});

Any non-401, non-5xx response from /auth/steam (e.g. a 403 from Cloudflare's WAF, or a 429 rate limit) falls into the "network" bucket, which renders as "Can't reach OpenFront. Check your connection." — but the request did reach the server. This codebase already documents WAF 403s as a real, previously observed failure mode for this exact desktop client (see the refused case in multiplayerAllowed's doc comment in DesktopShell.ts, referencing OPE-192, and src/server/Master.ts's note that descriptor endpoints "must be reachable without a bot challenge"). Telling a player to check a working connection is the same class of misdirection as the Turnstile message this PR exists to replace.

Suggested fix: Map the unclassified/non-5xx-non-401 bucket to "steam-error" (the existing generic reason) instead of "network", so the message doesn't falsely imply a connectivity problem.


Note: a sessionLabel() default-case inconsistency with ticketReason()'s exhaustive switch was considered but not included — it's a necessary default for an optional field (DesktopSessionState.reason is optional), not a defect.

@Celant Celant added this to the v34 milestone Aug 31, 2026

getTicket() trusted bridge.getAuthTicket()'s shape. Against a shell
older than this client's SteamTicketResult contract, a successful
sign-in (a bare string) was read as a failure, and a legacy null threw
a TypeError instead of degrading. Normalise string/null/undefined into
the typed result, per the same must-degrade convention DesktopShell.ts
already follows for a client newer than its shell.

Also bound the IPC call itself at 8s, above the shell's own 5s
watchdog on the native Steam call, so a hung shell can't leave the
session pinned at "retrying" (which the status bar renders no button
for) the way the unbounded call could.
… failures

Four related fixes to DesktopSessionState transitions, all converging
on the same failure mode: multiplayerAllowedForSession gates on every
non-signed-in status including "retrying", and the status bar renders
no button for "retrying" -- so any path that can rest there is an
unrecoverable lockout, and any path that asserts a Steam failure for a
non-Steam event mis-gates and mis-messages the player.

- ticketReason() gets a default (steam-error) so a malformed reason
  from a misbehaving/old shell can't return undefined at runtime
  despite the non-optional SessionFailureKind return type.

- clearLocalSession() now publishes {status:"unknown"} instead of
  asserting {status:"signed-out", reason:"steam-error"}. logOut() runs
  on any 401 from /users/@me, on key rotation, and on an iss/aud claim
  mismatch -- none of which mean Steam sign-in failed. "unknown"
  doesn't gate, and the next userAuth() re-establishes the real state.

- retrySteamSignIn()'s finally now forces a terminal signed-out state
  if the status is still "retrying" when it settles. refreshJwt()'s
  finally has no catch, so an exception inside doRefreshJwt() (e.g.
  steamSDK.getTicket() rejecting) propagates to userAuth()'s top-level
  catch, which logs and returns false without touching session state --
  leaving "retrying" published forever with no way out.

- doSteamLogin now maps a non-401, non-5xx /auth/steam response (a
  Cloudflare WAF 403, a 429) to "steam-error" instead of "network".
  The request reached the server, so "Can't reach OpenFront. Check
  your connection." was the wrong message.

src/client/Auth.tsclearLocalSession() clobbers a diagnosed signed-out session state back to unknown, silently un-gating multiplayer and hiding the status bar

```ts
if (steamSDK.isOnSteam() && __sessionState.status !== "retrying") {
setSessionState({ status: "unknown" });
}
```

The only guard here is status !== "retrying" — it is not scoped to hadSession (which is computed just above and used only for announceLoggedOut()). This means the block also fires when the current state is already a terminal {status: "signed-out", reason: "steam-*"} — i.e. exactly the diagnosed-failure state this PR introduces.

clearLocalSession() runs unconditionally inside logOut()'s finally, and logOut() is called from ~13 call sites in src/client/Api.ts on any bare 401 response, without checking whether a JWT was actually present (getAuthHeader() returns "" rather than throwing when logged out, so the request still goes out and still comes back 401).

Concrete repro: Steam ticket wedges → doRefreshJwt correctly publishes {status: "signed-out", reason: "steam-wedged"} (bar shows "Steam couldn't verify your session…", multiplayer gated — the intended behavior). Player then triggers any authenticated action (e.g. updateUsername, claimReward, setMarketingConsent) → getAuthHeader() returns "" → server returns 401 → await logOut()clearLocalSession() → since state is "signed-out" (not "retrying"), the block above fires and resets it to {status: "unknown"}. multiplayerAllowedForSession treats unknown as allowed, so the bar disappears and multiplayer un-gates with no explanation — reopening the exact bug this PR exists to fix (the next join produces the raw "Unauthorized: Turnstile token rejected" error again).

This path is untested: tests/client/Auth.steam.test.ts only covers logOut() starting from the initial unknown state, not the signed-outunknown downgrade.

Suggested fix: narrow the guard so it only resets a genuine stale signed-in session, not an already-diagnosed failure, e.g.:
```ts
if (steamSDK.isOnSteam() && __sessionState.status === "signed-in") {
setSessionState({ status: "unknown" });
}
```
(or equivalently !== "retrying" && !== "signed-out"), and add a test asserting that logOut() from a signed-out state preserves the reason.


🤖 Generated with Claude Code

CodeRabbit on #5185. normaliseTicketResult defended the legacy string
and null shapes but cast any object carrying an `ok` property, so a
malformed { ok: true } from a mismatched shell could still be POSTed to
/auth/steam as a bogus ticket -- a half-done check at a trust boundary.

A success now needs a non-empty string ticket or it degrades to
steam-error. A malformed FAILURE needs no check here: an unrecognised
reason is already covered by ticketReason's default.

Asserted end to end as well as at the SDK, since /auth/steam is what
would have received it.

🤖 Claude Code Review

Verdict: No issues found — this PR is ready as-is. Findings: 0 critical, 0 major, 0 minor.

Reviewed the full diff (src/client/Auth.ts, DesktopShell.ts, SteamSDK.ts, GameModeSelector.ts, Main.ts, components/DesktopUpdateBar.tsDesktopStatusBar.ts rename, DetailedGameViewModal.ts, index.html, resources/lang/en.json, and 8 test files) across four independent passes: two CLAUDE.md compliance audits and two bug/security scans (diff-only and introduced-code-focused).

CLAUDE.md compliance: Clean. All new user-facing strings route through translateText() with matching entries added to resources/lang/en.json only (no other translation files touched). No src/core/ files are touched, so the determinism/core-test rules don't apply. New session-state logic (multiplayerAllowedForSession, retrySteamSignIn, ticket-failure-reason mapping) is covered by new/updated tests (DesktopShellSession.test.ts, DesktopStatusBar.test.ts, and updates across Auth.steam.test.ts, SteamSDK.test.ts, GameModeSelectorGating.test.ts, etc.).

Bugs/logic/security: No significant, high-confidence issues found. Reviewers traced the DesktopUpdateBarDesktopStatusBar rename for dangling references (none found), the retrySteamSignIn single-flight guard (sound — finally cannot null the in-flight promise before it's returned), normaliseTicketResult's null/undefined narrowing (safe), and the removed Steam→/auth/refresh fallthrough in doRefreshJwt (correctly prevents transient Steam hiccups from wiping the persistent player ID via a full logout).

Two minor, non-blocking observations were surfaced but are not being flagged as defects: a slightly stale code comment in Auth.ts about ticketReason's exhaustiveness, and the fact that clearLocalSession publishes an "unknown" session state during Steam logout (briefly leaving multiplayer ungated) — both reviewers noted this appears to be a documented, self-healing tradeoff rather than a bug.

Claude Code review on #5185. The previous guard skipped only "retrying",
so clearLocalSession reset an already-diagnosed {signed-out, steam-*} to
"unknown" -- which does not gate. The bar vanished and multiplayer
un-gated, handing the player back the raw Turnstile error this work
exists to remove.

Reachable, not theoretical: getAuthHeader returns "" once signed out, so
an authenticated call still fires and still comes back 401, and Api.ts
calls logOut() on 401 from 13 places.

The guard is now scoped to "signed-in" -- the one state that is a lie
after a session is dropped, and the only one this was ever meant to fix.
Every other status survives untouched.

The previous round's test asserted the clobbered behaviour from an
ambient state; it now establishes signed-in first and asserts the
downgrade, and a new test pins that a diagnosed signed-out survives an
unrelated logOut.

293-293: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Handle a rejected Steam ticket during initial authentication.

If steamSDK.getTicket() rejects, doRefreshJwt() exits before this signed-out transition. userAuth() catches the rejection and leaves the session state as unknown. multiplayerAllowedForSession() allows unknown, so failed initial Steam authentication can permit multiplayer and hide the session failure.

Catch the ticket rejection and publish { status: "signed-out", reason: "steam-error" }. Add an initial getAuthHeader() rejection test.

🤖 Claude Code Review

Verdict: No issues found — 0 findings (0 critical, 0 major, 0 minor).

Reviewed the full diff for CLAUDE.md compliance (i18n/translateText coverage for all new desktop_session.* strings, translation-file scope, comment/abstraction conventions) and for bugs (compile correctness, gating logic, async/race behavior, event wiring, and trust boundaries around the Electron bridge). Two candidate issues surfaced during review and were both ruled out after checking the actual final diff and file contents:

  • A claimed dangling reference to a removed s variable in DesktopStatusBar.ts's progress-bar markup — the relevant lines actually call this.percent(), not s; no undefined reference.
  • A claimed no-op in clearLocalSession()'s downgrade of a stale "signed-in" state to "unknown" — the full comment (only partially visible in an earlier commit) explicitly documents this as an intentional, narrowly-scoped fix for a stale state label, not an attempt to close a gating hole for unrelated 401s (key rotation, iss/aud mismatch), which correctly should not be attributed to Steam.

Checked for bugs and CLAUDE.md compliance.
