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

Summary by CodeRabbit

  • Bug Fixes

    • Corrupted or unreadable saved credentials are now distinguished from missing credentials across authentication and profile views.
    • Authentication commands preserve and display actionable storage and configuration errors.
    • Windows credential-store failures are reported accurately instead of as missing credentials.
    • Risk-control configuration failures no longer disable host-signal collection by default.
  • Improvements

    • Recovery guidance is more specific, including downgrade guidance where applicable.
    • Authentication status and JSON output include structured error details and clearer recovery notes.
    • Malformed configuration errors are now surfaced consistently during authentication operations.
    • Trusted credential-source information is preserved when host-signal collection is disabled.

📝 Walkthrough

Walkthrough

The change preserves stored-token and keychain errors instead of treating them as missing credentials. It adds structured identity diagnostics, recovery-hint projection, command-level error reporting, revised login scope output, and separate handling for risk-control host signals and credential-source metadata.

Changes

Credential diagnostics

Layer / File(s) Summary
Stored-token validation and error propagation
internal/auth/..., internal/keychain/...
GetStoredToken returns errors and validates decoded tokens. Keychain and Windows registry failures retain typed storage information.
Structured identity and command diagnostics
internal/identitydiag/..., cmd/auth/..., cmd/profile/..., cmd/doctor/..., cmd/whoami/...
Identity results support an error status and structured errs.Problem data. Auth and profile commands distinguish missing tokens, corrupt tokens, and malformed configuration.
Caller migration and login output
internal/credential/..., shortcuts/mail/..., sidecar/..., cmd/auth/login_result.go
Callers adopt the error-returning token lookup. Login output renders status messages and revised granted and missing scope sections.
Recovery hint projection and command wiring
internal/recovery/hint.go, internal/surface/plan.go
Keychain recovery hints can reference the keychain downgrade command. Recovery projection filters unavailable command targets.

Risk-signal transport

Layer / File(s) Summary
Risk policy and header injection
internal/cmdutil/risk_control.go, internal/riskcontrol/transport.go
Missing or unreadable configuration leaves host-signal collection enabled. Nil host sources suppress host signals but do not suppress trusted credential-source metadata.
Risk-signal behavior validation
internal/cmdutil/*_test.go, internal/riskcontrol/*_test.go
Tests cover configuration defaults, forged headers, host-signal suppression, and request-scoped credential-source transmission.

Priority: ➖ Normal

Estimated code review effort: 4 (Complex) | ~60 minutes

Severity of issue fixed: Medium

Merge Risk: 🟡 Moderate · up to b9de5

This change improves credential-failure reporting and recovery guidance, but a corrupted stored credential may still be treated as a successful empty-scope result and login output may omit requested-but-ungranted scopes. The remaining regression coverage concerns should be addressed before merge.

Assert the typed error contract.

This test checks only err.Error(). It can pass for a different error with the same text. Assert the expected typed error metadata and the preserved cause when one exists. The existing exit-code assertion does not replace those checks.

As per coding guidelines, error tests must assert typed metadata and cause preservation rather than message text alone.

Comment thread cmd/auth/login_result.go
…rrors

A stored token that fails to decode or fails semantic validation is now
reported as internal/storage but carried no recovery hint, so `api --as
user`, `auth check`, `auth status`, and `doctor` all ended in a dead end.
A new login overwrites the damaged entry, so attach the canonical
user-authorization recovery on the two read-side corruption branches.
The write-side validator stays hint-free: a rejected write leaves nothing
on disk to re-authorize.

`auth status` keeps the storage failure in `note` and appends the recovery
instead of replacing it.

Tests pin the hint on GetStoredToken, GetValidAccessToken, identitydiag
(including reduced-distribution projection when auth login is concealed),
auth check, and auth status, and pin that SetStoredToken replaces a
corrupt entry.
