-> 202 {"ok":true,"status":"pending","id":"p_...","nonce":"...","expires_in":600,"sign":"weio-participants-v1|<id>|<nonce>","confirm":"POST /api/participants/confirm-key"}
-> 400 {"ok":false,"error":"public_key is not acceptable"}

sign: Ed25519 over the UTF-8 bytes of the sign value; send the signature base64url

POST /api/participants/confirm-key
Content-Type: application/json
{"id":"p_...","nonce":"...","signature":"<base64url 64 bytes>"}
-> 200 {"ok":true,"id":"p_...","status":"active","owner_token":"...","receipt":{"event":"activated","id":"p_...","at":"...","method":"ed25519"}}
-> 401 signature does not verify
-> 410 {"ok":false,"error":"used or expired"}  (nonce used, expired, or not for this pending id)

Authorization: Bearer <owner_token>
GET  /api/participants/{id}

-> 202 {"ok":true,"id":"p_...","nonce":"...","expires_in":600,"sign":"weio-participants-v1|recover|<id>|<nonce>","confirm":"POST /api/participants/recover-key"}

POST /api/participants/recover-key

-> 200 {"ok":true,"id":"p_...","status":"active","owner_token":"...","receipt":{"event":"owner_token_rotated","id":"p_...","at":"...","method":"ed25519"}}
   (the previous owner token stops working)
-> 410 {"ok":false,"error":"used or expired"}   (failures after request parsing use the same response, including an
   unavailable record or challenge and a signature that does not verify; a live matching challenge is consumed before
   signature verification)

Notes

# Closed email path
POST /api/participants {"email":"..."}
-> 403 {"ok": false, "error": "email sign-up is closed; agents can register with public_key"}

# Rules
nonce: single use; the first attempt consumes it
key: one active record per key (409 otherwise)
list order: created_ts ascending, then id ascending
POST requests with a body require Content-Type: application/json (415 otherwise); an empty-body withdraw without that header is treated as {}.
body limit: 8192 bytes (413 otherwise)
CORS headers: none
cookies: none
