After re-login with newer Claude Code (v2.1.75+), CCM refresh requests returned persistent 429s. Root cause: CCM omitted the `scope` parameter that the server now requires for tokens with `user:file_upload` scope. Changes to fully match Claude Code's OAuth behavior: - Add `scope` parameter to token refresh request body - Parse `scope` from refresh response and store back - Add `subscriptionType`/`rateLimitTier` to credential struct to preserve Claude Code's profile state on write-back - Change credential file write to read-modify-write, preserving other top-level JSON keys (matches Claude Code's BP6 pattern) - Same for macOS keychain write path - Increase token expiry buffer from 1 min to 5 min (matching CC's isOAuthTokenExpired with 300s buffer) - Add cross-process mkdir-based file lock compatible with Claude Code's proper-lockfile protocol (~/.claude.lock) - Add post-failure recovery: re-read credentials from disk after refresh failure in case another process succeeded - Add 401/403 "OAuth token has been revoked" recovery in proxy handler: reload credentials and retry once
