Root causes (verified live): the Claude keychain branch was never
enabled (allowClaudeKeychain never passed), security -w returns
hex-encoded JSON the parser rejected, and Codex had no keychain
discovery at all.
- shared readKeychainPassword: Apple-signed /usr/bin/security, 90s
window so the user can answer the macOS dialog, hex decode,
notFound vs accessDenied classification; secrets never logged
- Claude: keychain fallback active (gated to explicit Refresh so
launch never ambushes with a dialog); connection retained across
keychain-less background polls
- Codex sources in order: the menubar's own cached OAuth (read-only,
401 = one re-read, never rotate), legacy ~/.codex/auth.json
(writable), com.openai.codex plaintext if usable; Safe Storage
never decrypted
- new accessDenied state (amber, 'locked') + ConnectAffordance on
Plans cards and Settings rows: login command, keychain-Allow note,
force Refresh
Live verification: Claude connected with its real tier and windows;
Codex correctly accessDenied until the keychain dialog is allowed.
