- **X account credentials**: `POST /x/accounts` and `POST /x/accounts/{id}/reauth` transmit X account passwords (and optionally TOTP secrets) to Xquik's servers over HTTPS. Credentials are encrypted at rest and never returned in API responses. The agent MUST confirm with the user before calling these endpoints and MUST NOT log

`POST /x/accounts` and `POST /x/accounts/{id}/reauth` are **credential proxy endpoints** — the agent collects X account credentials from the user and transmits them to Xquik's servers for session establishment.
