# Bind Phone Send

`POST /api/user/profile/bind-phone-send`

Mint + send an OTP to the target phone for the caller to verify.

Pre-flight rejects if the phone is already bound to a DIFFERENT
user (409). Re-binding the SAME phone the caller already owns is
allowed — useful as a "re-verify" affordance.

Shares the phone_otp_codes table + 60s per-phone cooldown with
/api/auth/sms/send; the OTP minted here can also be consumed by
that endpoint and vice versa. The /confirm endpoint below is the
only thing that enforces who-owns-what at verify time, so cross-
flow OTP use is benign.
