 - **Spool Usage Lost When Spool Runs Empty Mid-Print** ([#459](https://github.com/maziggy/bambuddy/issues/459)) — When a spool ran empty during a print and the AMS auto-switched to a backup spool, the `on_ams_change` handler eagerly deleted the empty spool's `SpoolAssignment` record (fingerprint mismatch). When `on_print_complete` later ran, it queried `SpoolAssignment` live from the database, found nothing, and silently dropped usage. Now snapshots all spool assignments at print start into the `PrintSession`, so usage is correctly attributed at completion regardless of mid-print AMS changes.
 - **K-Profile Response Race Condition Crash** ([#462](https://github.com/maziggy/bambuddy/issues/462)) — An unsolicited or late K-profile MQTT response could crash the MQTT handler with `AttributeError: 'NoneType' object has no attribute 'set'`. The MQTT callback thread checked `self._pending_kprofile_response` (not None) at line 2698, but between that check and the `.set()` call, the asyncio thread's `finally` block in `get_kprofiles()` could clear the attribute to `None` after a timeout — a classic TOCTOU race. Fixed by capturing the event reference in a local variable before the check.
 - **Queue Stuck on "Busy" for "Any Model" Jobs** ([#435](https://github.com/maziggy/bambuddy/issues/435)) — When a print was queued with "Any [Model]" (e.g., "Any P1S"), it was created with `printer_id=NULL` and `target_model="P1S"`. After the assigned printer finished, the queue widget queried only for items matching `printer_id=X`, missing the next pending model-based item (`printer_id IS NULL`). With no next item found, the "Clear Plate & Start Next" button never appeared, leaving the scheduler stuck reporting "Busy". The queue API now accepts an optional `target_model` parameter; when combined with `printer_id`, it uses OR logic to also return unassigned items whose `target_model` matches the printer's model. The frontend passes the printer's model through to this query. Additionally, the backend now resolves the printer's model server-side from the database when the frontend doesn't provide `target_model` (e.g., when the printer was added without selecting a model), ensuring the OR logic works regardless of whether the client knows the printer's model.
+- **Queue "Any Model" Jobs Stuck in "Waiting" After Plate Clear** ([#435](https://github.com/maziggy/bambuddy/issues/435)) — After the queue visibility fix above, "Any Model" jobs were correctly assigned to an idle printer but immediately crashed with `'>=' not supported between instances of 'str' and 'int'` when computing AMS filament mapping. MQTT raw data returns AMS unit and tray IDs as strings, but `_build_loaded_filaments()` compared them to integers without casting. The crash prevented the assignment from committing, so the scheduler retried every 30 seconds in an infinite loop. Cast `ams_id` and `tray_id` to `int()` to match the pattern already used for external spool IDs.
 
 ### New Features
 - **Background Print Dispatch** ([#408](https://github.com/maziggy/bambuddy/pull/408), [#112](https://github.com/maziggy/bambuddy/issues/112)) — Printing from archives and the file manager now runs in the background via an async dispatch service. FTP uploads and print-start commands are decoupled from API request latency, so the UI responds immediately. Real-time progress is streamed to all clients via WebSocket, rendered as a persistent toast with per-job upload progress bars, status badges (dispatched/processing/completed/failed/cancelled), and a cancel button. The dispatcher supports concurrent uploads to different printers with per-printer queuing to prevent conflicts. Cancellation is cooperative — uploads abort at the next chunk boundary and clean up partial files on the printer. Batch progress tracking shows overall completion across multi-printer dispatches. Translations added for all 6 locales (en, de, fr, it, ja, pt-BR).
