Prevent raw exception messages from leaking stack frames or absolute
paths in the console logs and token health endpoints.
Also harden the i18n mirror move script by replacing shell-based git
commands with execFileSync and a safer fallback for untracked files.
Embed Gemini, Antigravity and Windsurf public OAuth/Firebase identifiers
(extracted from upstream CLI binaries) through a XOR-masked byte sequence
in open-sse/utils/publicCreds.ts instead of source literals, so pattern
scanners (GitHub Secret Scanning, Semgrep) stop raising false positives on
every release. decodePublicCred passes raw values through unchanged for
users who already have plaintext in their .env (no migration needed).
- New utils/publicCreds.ts with decode/encode + tests
- Replace 6 hardcoded Google client_id/secret in oauth.ts + providerRegistry
- Drop literals from .env.example (comment-only documentation)
- Sanitize error messages inside buildErrorBody so every caller (incl.
createErrorResult) is covered; cursor.ts now reuses the shared helper
- Cover the new helpers with unit tests (publicCreds + error sanitization)
Resolves the open code-scanning js/stack-trace-exposure findings and the
secret-scanning Google API Key alert without breaking existing setups.
