extra_sessions_update_unconfirmed
The capacity operation is saved, but its provider outcome is not fully confirmed. Retry the requested quantity to reconcile it from a fresh provider read; a signed subscription webhook can also complete it. A matching quantity alone does not prove which operation applied. Only the frozen request may be redispatched, under its original idempotency key and within the bounded retry window; older uncertainty requires billing support. No conflicting purchase is dispatched while ownership remains unresolved.
Problem shape
Every non-2xx response is an RFC 9457 application/problem+json body. The type URI below is stable and machine-matchable, so branch on the final path segment (the code) and treat the status as redundant confirmation. See the error-handling guide.
