# Legacy covenant enrolment (time-boxed)

`POST /v1/me/covenant/enrol`

## Request

- Base URL: `https://api.lithtrix.ai` (the document declares no server; this is the origin it was published from)
- URL: `https://api.lithtrix.ai/v1/me/covenant/enrol`
- Auth: none declared

For agents with no covenant row, inside the legacy window. Requires root ``ltx_*`` and a passport signature over ``canonical_covenant_amend_bytes_v1``. Proves current control, not ownership at registration — deliberately weaker than register-time enrolment. After the window, use is closed.
