The shape-of-payload dump shipped earlier rules out cache wipes — shaddowlink's round-1 captures show AMS data reaches the slicer byte-identical to what the printer sent. The remaining symptom (picking a generic filament in archive mode "unloads" the slot) lives on the command path, which the snapshot dump doesn't see: it writes only the cached _latest_print_state and the periodic 1Hz push. Add append_event() in _debug.py — same env flag, separate file at <log_dir>/vp_wire/<vp>_cmd.jsonl. One JSONL line per event with UTC iso timestamp, direction (slicer_to_bridge / printer_to_slicer), MQTT topic, <channel>.<command> grep handle, and parsed payload. Wired at two points: mqtt_server._handle_publish for slicer publishes (after JSON decode so the trace matches what the bridge actually parsed) and mqtt_bridge._on_printer_raw "everything else" branch for printer responses (after serial rewrite so the trace matches what the slicer sees on the wire). Pushall / get_version stay out — both are handled locally and never round-trip through the bridge. Bytes payloads get the same \x00-tolerance fix from #927 so OrcaSlicer's C-string-null publishes parse cleanly; un-parseable bytes fall back to {"raw": "..."} so every line stays valid JSON.
