Right after the slicer picks a filament for the external spool (vt_tray, ams_id=255),
Bambu firmware pushes a partial vt_tray carrying just {tray_info_idx, tray_color} -
~18 fields shorter than the pushall shape the slicer expects. The #1622 round-4
per-field accumulate (da799447) only carried over prev keys NOT in new, so the
cached vt_tray was replaced wholesale with the 2-field partial. The next 1 Hz
cached-as-base push delivered the stripped dict and BambuStudio rendered the
external slot as invalid (color only, no tray_type / state / k / n / cali_idx /
nozzle_temp_*). Reload restored it because the reconnect-triggered pushall
re-seeded vt_tray, then the cycle repeated. AMS slots didn't suffer because
_merge_ams_dict deep-merged them.
Fix: for every top-level push_status key whose prev AND new are both dicts,
overlay incoming keys onto prev rather than replace. ams is excluded (already
deep-merged). The same shape protects device / online / upgrade_state / ipcam /
upload / net against future firmware partials. net.info IP rewrite is unaffected -
_rewrite_net_info_ips runs before caching and overlay lets the freshly-rewritten
list win over prev when present.
