SpoolBuddy "Assign to AMS" with a Bambu Cloud user preset (PFUS) left
Bambu Studio showing "Generic <Material>" instead of the user's
custom preset. Root cause: the defensive filter that catches
PFUS/PFCN leaks into tray_info_idx also cleared setting_id —
but PFUS/PFCN are VALID setting_id values, just not valid
tray_info_idx values. When the cloud detail lookup didn't return
a filament_id (cloud unauth on the on_ams_change replay path,
transient failure, or older custom presets), both fields got
cleared and the caller's generic-material fallback overwrote
setting_id with GFSG99 — slicer resolved to Generic PETG.
Fix: the filter still clears tray_info_idx for PFUS/PFCN/material-
name leaks, but preserves setting_id when it's a valid slicer
reference (PFUS / PFCN / GFS). Material-name leaks still clear
both. Post-fix MQTT carries tray_info_idx=GFG99 (firmware-acceptable
for HMS/drying/colour) AND setting_id=PFUS<hash> (slicer uses this
to load the actual user preset).
What stays the same: Bambuddy's own AMS card still displays
the generic material on cloud-unauth paths — same fundamental
limitation as today. Fixing that needs a deeper layered fallback
(LocalPreset name match, printer kprofile query, cloud-detail
cache) and is out of scope for this drop. Slicer-side fix is
the reporter's explicit ask.
