- Anchor CRED_DIR/KEY_PATH to __file__ (not CWD) in credential_store.py
- Fix email PUT: separate password pop from sentinel discard (was fragile or-chain)
- Fix email test: always use stored credential, remove password override path
- Move integrationResults into system store (was view-local — spec violation)
- saveFilePaths/saveDeployConfig write to dedicated error refs, not saveError
- add scripts/credential_store.py (keyring/file/env-ref backends, Fernet encryption)
- email password stored via credential store, never returned in GET
- email GET returns password_set flag; PUT accepts new password or ${ENV_VAR} ref
- move integration actions to store (connectIntegration, testIntegration, disconnectIntegration)
- add tier-gating UI with locked state and upgrade prompt
- move subprocess/socket/imaplib/ssl imports to top level
