Surface	Evidence	Wave-one choice
BambuStudio CLI	BambuStudio/src/libslic3r/PrintConfig.cpp:9941-10090: CLIActionsConfigDef describes slice (0 all plates), export_3mf, info, etc.	dev/extract_catalog.clj extracts 57 active actions/transforms/misc options (18 actions) including name, type, tooltip and optional CLI spelling to resources/hive_bambu/slicer.edn; pure argv builder, no subprocess yet.
Printer reports	BambuStudio/src/slic3r/GUI/DeviceManager.cpp:2560-2600 handles full and delta print.push_status messages, requests pushall when diff reconstruction fails.	report projects an already-decoded report; no false claim of complete state reconstruction.
LAN MQTT	bambu-mcp/src/mqtt-client.ts:222-280,318-340,365-388,390-553 publishes device/<id>/request, matches response sequence IDs, uses pushing.pushall, print.pause/resume/stop/print_speed/gcode_line, AMS, LED, project_file. mcp-bambu/bambu_mcp/printer.py:36-78,121-147 confirms TLS 8883, device/<serial>/report, pushall, basic print commands.	Extract 17 sendCommand names with dev/extract_mqtt.clj; portable topic/payload/report values, injected PrinterTransport only. No MQTT connection, TLS or signing in wave one.
Printer authorization	bambu-mcp/src/mqtt-client.ts:285-313: optional RSA-SHA256 signing header (sign_ver, sign_alg, cert_id, payload_len) when credentials present.	Signing belongs to a future adapter; unsigned payload value is NOT an authorization claim.
G-code safeguards	bambu-mcp/src/safety.ts:4-54: six blocked commands; nozzle >300 C, bed >120 C.	dev/extract_safety.clj emits six tokens, portable core checks those, temperatures and refuses multiline commands.
Python bridge	mcp-bambu/bambu_mcp/printer.py:1-42 imports paho-mqtt; its FTPS path calls curl via subprocess.	Future :python adapter imports Python via libpython-clj; do not call its curl shell path.
3MF model	bambu-mcp/src/mqtt-client.ts:420-470 uses Metadata/plate_<n>.gcode inside uploaded 3MF.	Minimal object-ID view over already-unzipped XML text. DTD/entity declarations refused; this is not a general XML parser or a ZIP reader.

The references are BambuStudio (AGPL-3.0; the addon follows AGPL-3.0-or-later), bambu-mcp (MIT; LICENSE:1-21), and mcp-bambu (MIT; LICENSE:1-21). An in-process libslic3r C ABI (hive_call/hive_free) is planned, not implemented. This wave contains extracted descriptive facts, not copied implementations. No printer, FTPS endpoint, slicer executable or 3MF archive was exercised here.

Planned adapters: JVM :python via libpython-clj importing bambu_mcp, cljs Node requiring npm mqtt and basic-ftp, cljrs Rust cdylib MQTT/TLS, and :slicer invoking the BambuStudio CLI (the single allowed subprocess, built from source). Each must be separately implemented, tested and authorized before use.
