- Cross-workspace and cross-project access is rejected from the credential's server-side ownership fields.
### AI-native access instead of password sharing
- `.env` files, access tokens, API credentials, cookies, private keys, recovery codes, or generated agent credentials;
- staging smoke tests cover login, project creation, context read, progress write, credential revocation, backup, and rollback;
