Two defects live-drilled in the break-glass staff provisioning:
- An Owner reset that typed any username other than the occupied seat took
UpsertOwner's insert arm and silently minted a SECOND owner row, leaving the
existing seat — possibly the compromised account the reset was meant to
replace — live; every owner row is undeletable through the panel, so the tier
could never converge back to one. provisionOwner now refuses with
ownerSeatTakenError naming the seat (recoverable: the TUI routes back to the
form); bootstrap still mints, and the seat's own username still resets in
place. PGRepo gains OwnerUsername for the guard.
- InsertOperator returned the raw driver error on a taken username while the
console keys its rename prompt off api.ErrConflict — the "choose another
name" leg died with SQLSTATE 23505 against real Postgres (the fake encoded
the contract; PGRepo had drifted). Map the unique violation to ErrConflict
and pin it in pgint.
Live (auditfix37): fresh username refused naming the seat; seat reset kept the
id/email with still exactly one owner; taken operator name returned to the form
with the retry note, and the retyped name succeeded (drill rows cleaned).
