fix(claude): report a signed-out Claude CLI as unauthenticated

[none23]

What Changed

• The Claude provider probe reports a signed-out first-party CLI as Not authenticated instead of Authenticated.
• The probe reads the SDK's apiKeySource next to tokenSource, so API-key setups (which also report tokenSource: "none") stay authenticated. Bedrock, Vertex, gateways, and older CLIs that omit tokenSource are unaffected.
• The status message reuses the sign-in guidance from fix(claude): name the expired login or usage limit instead of a generic API error #10321, including the instance's CLAUDE_CONFIG_DIR.
• The Claude user guide gets a short section on what to do when an instance shows as signed out.

Why

A logged-out Claude CLI still completes the SDK initialization handshake, and the probe treated any successful handshake as authenticated. Settings then showed a green "Authenticated" badge while every turn failed on login.

#10321 fixed the turn-side message. This is the remaining Settings half tracked in #7690. It infers the state from fields the init handshake already returns, so the periodic probe spawns no extra process. #7691 addresses the same issue by running claude auth status as a second subprocess per probe.

Closes #7690

Summary by CodeRabbit

• Bug Fixes

  • Claude integrations now correctly report an unauthenticated status when the first-party CLI is signed out without an API key.
  • API-key authentication continues to be recognized correctly.
  • Signed-out Claude sessions now provide clearer authentication status information.

• Documentation

  • Added guidance for signing in to Claude, using the appropriate configuration directory, and restarting threads after authentication.
  • Documented that existing threads may retain their signed-out process until restarted.

Note

Report signed-out Claude CLI as unauthenticated in checkClaudeProviderStatus

• probeClaudeCapabilities now reads the API-key source from the Claude SDK initialization account data and includes it in the capability snapshot.
• checkClaudeProviderStatus treats first-party results with token source none and no API-key source as unauthenticated: the provider stays installed but gets error status, an unauthenticated auth status, and a signed-out message referencing the Claude configuration directory.
• First-party results that include an API-key source continue through the authenticated path.
• Tests in ClaudeProvider.ts, ClaudeCapabilitiesProbe.test.ts, and ProviderRegistry.test.ts cover both the logged-out and API-key scenarios.
• Docs in providers-claude.md add a Signed out section guiding users to run Claude authentication with the same configuration directory used by the instance.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This production change alters Claude authentication status reporting, making it an authentication-sensitive runtime change. An unresolved Medium finding also identifies that apiKeySource="none" can bypass the signed-out classification, so the behavior needs human review.

📝 Walkthrough

Walkthrough

The Claude provider now uses apiKeySource to detect signed-out first-party CLI sessions. Tests cover signed-out and API-key authentication. Documentation explains login with the configured Claude directory.

Changes

Claude authentication status

Layer / File(s)	Summary
Capability authentication data apps/server/src/provider/Layers/ClaudeCapabilitiesProbe.test.ts, apps/server/src/provider/Layers/ClaudeProvider.ts, apps/server/src/provider/Layers/ProviderRegistry.test.ts	The capability probe and test fixtures now include optional apiKeySource data.
Signed-out status handling apps/server/src/provider/Layers/ClaudeProvider.ts, apps/server/src/provider/Layers/ProviderRegistry.test.ts, docs/user/providers-claude.md	When a first-party session has tokenSource: "none" and no apiKeySource, the provider reports an unauthenticated error. Tests cover API-key authentication. Documentation describes reauthentication with the configured Claude directory.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~20 minutes

Severity of issue fixed: Medium

Merge Risk: 🟡 Moderate · up to 711ae

Signed-out Claude instances with a custom binary can receive login instructions for a different CLI installation, leaving chats unable to authenticate. Update the guidance to use the configured or resolved binary before merge.
