Detects the printer-side variant of install step 4 — many users (esp. on
clean installs) forget to enable this and only notice when their archive
cards have no thumbnails. The diagnostic now catches it upfront.
Detection: read state.store_to_sdcard, which Bambuddy already parses from
MQTT push_status home_flag bit 11 (bambu_mqtt.py:153). Instant, no I/O.
An FTP upload-and-verify probe was tried first and rejected. /cache is
always writable from Bambuddy regardless of the slicer setting — only
BambuStudio's own behaviour changes when the toggle flips, not the
printer's acceptance policy. Confirmed empirically against X1C + H2D
with the slicer option toggled off: probe succeeded, home_flag bit 11
stayed True. So the only reliable signal is what the printer actually
reports about its own state.
Limitation: the printer-side variant only exists on newer firmware
(P2S 01.02 / Bambu Studio 2.6+). On older versions the toggle lives
only in the slicer and the printer never hears about it, so this check
will pass even when the user is missing step 4 in BambuStudio. The
skip-text and the wiki call this out explicitly. A reactive banner on
the no-3MF archive-fallback path is planned as a follow-up to cover
that case.
Statuses:
- pass: state.store_to_sdcard is True
- fail: state.store_to_sdcard is False (-> overall escalates to problems)
- skip: no live state, disconnected, or field never populated
