# Record the signer's consent to electronic signature

`POST /api/signer/consent`

Appends `participant.consented` with the request's IP and user agent as audit facts (spec §7). Idempotent: a participant who already consented gets their original consent timestamp back. Allowed only when it is the signer's turn.

## Response `200`

Consent recorded (or already on record)

- object
  - `consentedAt` string, date-time, required

## Other responses

- `401` — Missing, invalid, expired, or reissued signing link
- `404` — The link's envelope or participant no longer exists
- `409` — Not the signer's turn, or the envelope is no longer active
