# Claim Guest Session

`POST /auth/claim-guest-session`

Carry a guest session's call data onto the account that just logged in.

Nancy, 2026-08-26: "when a student does a whole class as a guest and then
creates an account or joins after the class finishes, does their transcript
from that class get carried over?"

Signing UP already did this — `_transfer_anonymous_call_data` runs on
registration and on the OAuth merge. LOGGING IN did not, and for a school
that is the common half: a student who already has a FluenTea account joins
the class by code without logging in, does the whole hour as a guest, and
then signs in. Their transcript, their presence in that room and therefore
their attendance all stayed on the throwaway guest row.

Two guards, because this moves data between accounts:
  * the source must actually BE anonymous — never another real account;
  * and recent. A stale `anonymous_user_id` in a shared browser's storage
    must not hand a stranger's guest session to whoever logs in next week.
