`set_kprofiles_batch` defaults the field with
`p.get("nozzle_id", f"HS00-{diameter}")`, and a `dict.get` default only
fires when the key is *absent*. The restore always set the key —
`"nozzle_id": p.get("nozzle_id")` — so a backup that carries no nozzle_id
published `nozzle_id: null` to the printer instead. Printers that omit the
field (KProfilesView's own #1748 comments) are exactly why the default is
there, and it was unreachable from this path.
Set only when known, on the same precedence the `setting_id` line beside it
already uses: the live profile first, then the backup, then absent. Live
first is the point rather than a bonus — `nozzle_id` encodes the fitted
nozzle's type as well as its diameter (`HS00-` hardened vs `SS00-`
stainless), so a nozzle swapped since the backup makes the stored value
stale, and the write lands on the nozzle fitted now.
Read with `getattr`, matching the defensive read of `extruder_id` in
`_match_kprofile`: not every live profile carries every field, and
`test_a_live_index_that_reports_no_extruder_still_matches` is the standing
control for that.
Four tests, two of which fail without the fix. The `_live` double also
gained `nozzle_id` — it is a non-default field on the real `KProfile`
dataclass, so omitting it let the double license code the real object
would have accepted.
