fix: handle credential and config read failures

[kiraWangRuilong]

Summary

Fix corrupt stored-token handling so auth diagnostics report structured storage errors instead of treating damaged credentials as missing. Keep risk-control host signals default-on when workspace config cannot be read, and send trusted credential-source metadata independently of the risk-control preference.

Changes

• Add an error-preserving stored-token read path while retaining the existing best-effort compatibility helper.
• Report corrupt user credentials from auth status as status=error with an internal/storage problem without leaking token content.
• Disable host signals only for a successfully loaded explicit risk-control opt-out; missing or unreadable config remains default-on.
• Send X-Agent-Credential-Source for official API requests whenever a trusted request-scoped source is available, even when host signals are disabled.
• Preserve outbound-header spoof protection and add regression coverage for each behavior.

Test Plan

• Unit tests pass: go test -count=1 ./internal/riskcontrol ./internal/cmdutil
• E2E tests

📝 Walkthrough

Walkthrough

The changes preserve stored-token failures, report corrupt credentials as structured identity errors, and keep missing credentials distinct. Risk-control transport now sends trusted credential-source metadata independently from optional host signals.

Changes

Credential diagnostics

Layer / File(s)	Summary
Stored-token error-preserving reads internal/auth/token_store.go, internal/auth/token_store_test.go, internal/auth/uat_client.go	ReadStoredToken preserves storage and decoding errors. Best-effort access still suppresses errors. Tests cover missing and malformed credentials without exposing token content.
Structured identity error status internal/identitydiag/diagnostics.go, internal/identitydiag/diagnostics_test.go, cmd/auth/status_test.go	Identity diagnostics add StatusError and structured errs.Problem details. Auth status tests distinguish missing and corrupt stored tokens and verify output does not leak credentials.

Risk-signal transport

Layer / File(s)	Summary
Risk policy and header injection internal/cmdutil/risk_control.go, internal/riskcontrol/transport.go	Missing or unreadable workspace configuration enables host-signal collection by default. Credential-source headers remain independent from host-signal collection.
Risk-signal behavior validation internal/cmdutil/*_test.go, internal/riskcontrol/transport_test.go	Tests cover policy defaults, forged-header replacement, host-signal suppression, and trusted request-scoped credential-source transmission.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🔵 Low · up to 00cd2

The PR improves corrupt-credential diagnostics and preserves trusted metadata controls, but it changes auth-status JSON output, leaves one test dependent on external configuration, and allows limited metadata in some opt-out or configuration-failure cases. The PR is mergeable with explicit owner awareness and follow-up on these bounded compatibility, test-isolation, and privacy-behavior risks.

Full details: Linked Issues check

Explanation

The implementation addresses the main #1925 behavior by distinguishing missing credentials from corrupt stored tokens and preserving structured storage errors without leaking secrets. Required coverage for keychain failures, decryption failures, and background execution is not shown.

Resolution

Add or provide regression tests for keychain retrieval failures, decryption failures, malformed stored data, missing credentials, background execution, and sensitive-data protection. Confirm that each non-missing failure is reported with the required structured error and recovery hint.

Full details: Title check

Explanation

The title clearly identifies the main change: handling credential and workspace configuration read failures. It is concise and relevant, although it does not mention the related risk-control header behavior.

Full details: Description check

Explanation

The description includes all required sections and explains the motivation, implementation changes, tests, and related issue. The test plan does not include the template's manual verification item, and the checked E2E entry lacks details, but the description is otherwise complete and on topic.
