 ## [0.2.3b1] - Unreleased
 
 ### New Features
-- **Queue Timeline View** ([#823](https://github.com/maziggy/bambuddy/issues/823)) — The queue page now has a production schedule view showing when each print is estimated to finish. Events are sorted chronologically and grouped by hour, with cards showing the file name, printer, estimated completion time, and time remaining. Active prints show a live progress bar. Filter by "Show All", "Printing", or "Queued", and navigate between days. Click any event to edit or stop it. Toggle between List and Timeline views with the button group above the queue. Requested by @sanjay2409.
-- **Staggered Batch Start for Multi-Printer Jobs** ([#752](https://github.com/maziggy/bambuddy/issues/752)) — When sending a print to multiple printers via the queue, you can now stagger the starts to avoid power spikes from simultaneous bed heating. Enable "Stagger printer starts" in the schedule options to define a group size (how many printers start at once) and interval (minutes between groups). For example, 10 printers with group size 2 and interval 5 min will start in 5 waves over 25 minutes. Default group size and interval are configurable in Settings → Queue. Works with both ASAP and Scheduled timing — ASAP starts the first group immediately, subsequent groups get computed scheduled times. The stagger option is also available in the direct Print dialog when multiple printers are selected — prints are automatically queued with staggered start times, so you can close the browser and walk away. Requested by @UVCXanth.
-- **Plate-Clear Confirmation Setting** ([#752](https://github.com/maziggy/bambuddy/issues/752)) — New "Require plate-clear confirmation" toggle in Settings → Queue. When disabled, the scheduler starts queued prints automatically on printers with finished jobs without waiting for per-printer plate confirmation. Useful for farm workflows where plates are verified physically before starting a batch. Default is enabled (existing behavior preserved). Requested by @UVCXanth.

Useful for farm workflows where plates are verified physically before starting a batch. Default is enabled (existing behavior preserved).
 - **Settings Queue Tab** — New dedicated Queue tab in Settings consolidates queue-related settings: staggered start defaults and auto-drying configuration (moved from the Filament tab).
-- **Per-User Statistics Filtering** ([#730](https://github.com/maziggy/bambuddy/issues/730)) — Admins can now filter the Statistics page by user. A user dropdown appears in the stats header for users with the new `stats:filter_by_user` permission (Administrators only by default). Filter by a specific user to see their prints, filament usage, and costs, or select "No User (System)" to view prints without user attribution (e.g. slicer-initiated or pre-auth prints). The filter applies to all stats widgets and exports. Requested by @3823u44238.
-- **Bulk Printer Actions** ([#825](https://github.com/maziggy/bambuddy/issues/825)) — Select multiple printer cards and apply bulk actions from a floating toolbar. Toggle selection mode from the header, then click cards to select. Use "Select All", "Select by State" (printing, paused, finished, idle, error, offline), or "Select by Location" to quickly pick printers. Available actions: Stop, Pause, Resume, Clear Notifications, and Clear Bed — each button is smart-enabled based on the selected printers' current states. Confirmation modals for destructive actions (Stop, Pause, Clear Bed). The status summary bar now shows all printer states (printing, paused, finished, idle, error, offline). Requested by @therevoman.
-- **Prefer Lowest Remaining Filament** ([#805](https://github.com/maziggy/bambuddy/issues/805)) — New optional setting in Settings → Filament that prefers AMS spools with the lowest remaining filament during auto-matching. When multiple spools match the same type and color, the one with the least filament remaining is selected first. Helps consume partial spools before starting new ones. Applies to queue scheduling, print modal, and multi-printer mapping. Unknown remain values (e.g. external spools without sensors) are treated as full. Disabled by default. Requested by @Mofoss.
-- **REST/Webhook Smart Plug Type** ([#472](https://github.com/maziggy/bambuddy/issues/472)) — New "REST" smart plug type for controlling power via generic HTTP APIs. Works with any home automation platform that has an HTTP endpoint (openHAB, ioBroker, FHEM, Node-RED, etc.). Configure separate ON/OFF URLs with custom HTTP methods (GET/POST/PUT/PATCH), request bodies, and headers. Optional status polling via a GET endpoint with JSON path extraction for state, power, and energy monitoring. Fully controllable — supports auto on/off with prints, daily scheduling, sidebar quick-toggle, and power alerts. Requested by @Percy2Live.
-- **Configurable Default Print Options** ([#858](https://github.com/maziggy/bambuddy/issues/858)) — Print options (bed levelling, flow calibration, vibration calibration, first layer inspection, timelapse) now have configurable defaults in Settings → Workflow. Set your preferred defaults once and every new print dialog starts with those values. Still overridable per print. Requested by @NoahTingey.
-- **Batch Print Quantity** ([#342](https://github.com/maziggy/bambuddy/issues/342)) — Print multiple copies of a file in one step. The print and schedule dialogs now have a quantity field — set it to any number and the system creates that many queue items automatically. When quantity is greater than one, items are grouped into a batch for tracking. In the direct print dialog, the first copy prints immediately while the remaining copies are queued. The queue page shows a batch badge on grouped items. Batch progress and cancellation are available via the API. Requested by @cimdDev.

 ### Improved
 - **Queue Page Visual Refresh** — Compact stats bar replaces the five summary cards (saves vertical space), color-coded left borders on all queue items for instant status scanning, collapsible history section (collapsed by default), and condensed single-line rows for history items showing more prints at a glance.
 - **Developer Mode Detection for A1/P1 Printers** — Printers that don't send the `fun` field in MQTT status (A1, P1 series) now have developer mode detected via a probe command. After receiving the first full status update, Bambuddy sends a no-op external slot configure and checks whether the printer accepts or rejects it (`mqtt message verify failed`). Printers that do send the `fun` field (X1C, H2D, etc.) continue to use the existing bit-based detection. Developer mode state is re-checked on every reconnect.
 
 ### Fixed
-- **Filament Color and Subtype Inconsistencies** ([#857](https://github.com/maziggy/bambuddy/issues/857)) — Fixed several filament identification issues: (1) AMS slot popup showed generic color names like "Dark Gray" instead of Bambu-specific names like "Titan Gray" because the fallback skipped the Bambu hex color database. (2) "Silk+" subtype was missing from the known variants list, so the Edit Spool dropdown showed "Silk" instead. Also added "Tough+". (3) Gradient and Dual Color filaments were misclassified — PLA Basic Gradient was detected as "Basic" and PLA Silk Dual Color as "Silk" because the firmware only sends the base material in `tray_sub_brands`. Now detects gradient/multi-color/tri-color variants from the `tray_id_name` color code pattern (M\*/T\* suffixes). Reported by @lightmaster.
-- **External Spool Print Fails on P1S/P1P Without AMS** ([#854](https://github.com/maziggy/bambuddy/issues/854)) — Sending a print job to a printer with no AMS units and only an external spool (virtual tray 254) caused the printer to reject the command with "Failed to get AMS mapping table". The print command was sent with `use_ams: true` (the default), but firmware on printers without AMS hardware rejects that combination. Now automatically sets `use_ams: false` when all filament slots map to external spools or are unmapped. H2D-series printers are excluded since they use `use_ams` for nozzle routing. Reported by @UVCXanth.
-- **External Folder Scan 500 Error on 3MF Files** ([#846](https://github.com/maziggy/bambuddy/issues/846)) — Scanning an external folder containing .3mf files crashed with "Object of type bytes is not JSON serializable". The parsed 3MF metadata contained raw thumbnail bytes (`_thumbnail_data`) that were stored directly in the database JSON column without cleaning. Also removed a call to the non-existent `parser.extract_thumbnail()` method — thumbnail data is already available in the parsed metadata. Now uses the same `clean_metadata()` pattern as upload and zip extraction. Reported by @SMAW.
-- **Archives Capped at 50 Items** ([#843](https://github.com/maziggy/bambuddy/issues/843)) — The archives page only showed the 50 most recent prints due to a hardcoded API limit. Users with more than 50 archives could not see or access older entries. Fixed by fetching all archives and adding client-side pagination with configurable page sizes (25, 50, 100, 200, or All). Page size preference is persisted. Reported by @dcbaldwin.
+- **Filament Color and Subtype Inconsistencies** ([#857](https://github.com/maziggy/bambuddy/issues/857)) — Fixed several filament identification issues: (1) AMS slot popup showed generic color names like "Dark Gray" instead of Bambu-specific names like "Titan Gray" because the fallback skipped the Bambu hex color database.

Page size preference is persisted.
 - **Filament Usage Not Recorded When Auto-Archive Disabled** — When a printer had "Auto-archive completed prints" turned off, filament consumption was silently lost. The `on_print_complete` callback returned early before reaching the usage tracking code, so neither the internal inventory (AMS remain% deltas) nor Spoolman received usage data. Moved filament tracking to run before the archive check so usage is always recorded regardless of the auto-archive setting.
-- **H2D External Spool Uses Wrong Nozzle** ([#836](https://github.com/maziggy/bambuddy/issues/836)) — Prints sent from Bambuddy to dual-nozzle printers (H2D, H2D Pro) with external spools always routed to the wrong nozzle. The old `ams_mapping2` format used a shared `ams_id: 255` with `slot_id: 0/1` to differentiate external slots, but the firmware interpreted slot_id as the nozzle index (0=main/right, 1=deputy/left), routing filament to the opposite nozzle. Already fixed by the #797 `ams_mapping2` format change (per-tray `ams_id` instead of shared unit), but users on older builds still experience this. Printing the same file directly from the slicer worked correctly. Reported by @NoahTingey.

Printing the same file directly from the slicer worked correctly.
 - **SpoolBuddy "Add to Inventory" Failed Silently** — The quick-add button on the SpoolBuddy kiosk did nothing when tapped. The scale weight was sent as a float but the backend requires an integer, causing a Pydantic validation error. The error was silently caught with no user feedback, leaving the confirmation modal stuck open. Fixed by rounding the weight before sending, moving the modal close to a `finally` block, and adding an error toast with the actual API message.
 - **SpoolBuddy Dashboard Crash on Null Spool Fields** — Viewing a spool with null `subtype`, `brand`, `rgba`, or `color_name` on the SpoolBuddy dashboard crashed the UI (black screen). The spool prop construction used `displayedSpool?.subtype ?? sbState.matchedSpool!.subtype` — when the field was `null`, the `??` operator fell through to `sbState.matchedSpool` which could also be null, causing a TypeError. Fixed by picking one source object instead of mixing per-field fallbacks. Added a global React error boundary so future crashes show the error instead of a black screen.
 - **Plate Thumbnails 401 in Print Modal** — Multi-plate 3MF plate thumbnails in the print modal returned 401 Unauthorized when authentication was enabled. The backend returns bare URL paths for plate thumbnails, but the `PlateSelector` component used them directly in `<img src>` without appending the stream token. Fixed by passing the URL through `withStreamToken()`.
 - **Schedule Calendar Picker Opens Off-Screen** — Clicking the calendar icon in the print modal's scheduled mode opened the native date picker at the bottom of the viewport instead of near the date field. The hidden `datetime-local` input used `sr-only` positioning which anchored the picker off-screen. Fixed by positioning the hidden input inside the date field's container.
 - **SpoolBuddy Kiosk Display Blanking and Crashes** — The kiosk Chromium flags added in 0.2.2.2 caused display instability: `--js-flags=--max-old-space-size=128` crashed the V8 renderer when heap exceeded 128 MB, `--enable-low-end-device-mode` aggressively killed GPU rendering surfaces, and resetting `CHROMIUM_FLAGS` discarded the Pi's GPU defaults (`--enable-gpu-rasterization`, ANGLE/GLES) creating an unstable mixed CPU/GPU rendering path. Fixed by removing both flags, appending kiosk flags to Pi defaults instead of replacing them, adding a `wlr-randr` keep-alive loop to prevent display blanking, and adding `<screenBlankTimeout>0</screenBlankTimeout>` to the labwc config.
-- **Sidebar Bottom Icons Cut Off With Smart Plugs** ([#862](https://github.com/maziggy/bambuddy/issues/862)) — Adding smart plug buttons to the sidebar caused the bottom icon row to overflow and get partially cut off. The footer section could be compressed by the flexbox layout when the navigation area grew. Fixed by preventing the footer from shrinking, allowing the expanded icon row to wrap, and adding scroll overflow to the collapsed sidebar icon stack. Reported by @chrismaddahl.

 - **SpoolBuddy Boot Splash Polished** — New splash image displays only the SpoolBuddy logo (removed Bambuddy branding) with green glow bloom, radial gradient background, light rays, and vignette. A generator script (`generate_splash.py`) is included for easy customization. Also reduced redundant initramfs rebuilds during install by deferring the rebuild until after the Plymouth theme is configured.
 
 ### Security
-- **Token-Based Auth for Media Endpoints** — Camera streams, snapshots, thumbnails, timelapse videos, photos, QR codes, and cover images served via `<img>`/`<video>` tags now require a stream token query parameter (`?token=xxx`) when authentication is enabled. Previously these endpoints were unauthenticated because browser media elements cannot send `Authorization` headers. The frontend obtains a 60-minute reusable token via `POST /printers/camera/stream-token` (requires `CAMERA_VIEW` permission) and automatically appends it to all media URLs. Affects endpoints in camera, archives, library, printers, print-log, and external-links routes. When auth is disabled (default for local installs), behavior is unchanged — no token required. Reported by Sacha Vaudey via security email.

 ### Fixed
 - **Native Install Misdetected as Docker in LXC Containers** — The update check falsely identified native installs as Docker when running inside Proxmox LXC containers. The detection logic used `.git/` directory absence as a Docker fallback, but LXC containers may also lack `.git/` depending on how the install was deployed. Replaced the `.git/` fallback with a proper check of `/run/systemd/container` which only matches Docker/Podman/OCI runtimes, not LXC. Native installs in LXC containers now correctly show the in-app update button instead of Docker Compose instructions.
-- **Print Fails on Files With Spaces in Name** ([#824](https://github.com/maziggy/bambuddy/issues/824)) — Printing files with spaces in their filename (e.g. "Junktion Box PRO 90.3mf") caused the printer to silently ignore the print command and remain IDLE. The FTP upload succeeded, but the MQTT print command's `url` field (`ftp://file name.3mf`) contained unencoded spaces that the firmware couldn't parse. Fixed by replacing spaces with underscores in the remote filename before upload. Reported by @benjamdev.

 - **SpoolBuddy Low Filament Warning Missing Slot Number** — The status bar low filament warning showed "AMS B" instead of the specific slot like "B2". Now uses `formatSlotLabel` to display the full slot label (e.g. "Low Filament: PLA (B2) - 4% remaining").
 - **SpoolBuddy Read Tag Diagnostic Fails on NTAG Tags** — The `read_tag.py` diagnostic script had five issues preventing NTAG reads: (1) SAK `0x04` (MIFARE Ultralight family) was rejected as "unsupported tag type" — now accepts both `0x00` and `0x04`. (2) `ntag_read_pages` had TX CRC off (should be on per NTAG spec), no Crypto1 clear, and no IDLE→TRANSCEIVE state reset. (3) The PN5180 enters an unrecoverable state after an NTAG READ command — added full GPIO hardware reset between each 4-page batch. (4) Reading past the end of smaller tags (MIFARE Ultralight has 16 pages vs NTAG's 44+) caused a hard failure — now returns partial data gracefully. (5) `ntag_write_page`/`ntag_write_pages` had the same stale CRC/state issues plus unreliable ACK checking and post-write verification — synced with daemon.
 - **Delete Tag Leaves Stale Tag Type** — The "Delete Tag" button in the spool edit modal only cleared `tag_uid` but left `tray_uuid`, `tag_type`, and `data_origin` intact. All tag-related fields are now cleared together.
@@ -78,13 +78,13 @@ All notable changes to Bambuddy will be documented in this file.
 - **Frontend Not Updating After Deploy** — The service worker used stale-while-revalidate for JS/CSS assets, serving the old cached bundle even after a new build was deployed. Changed to network-first for JS/CSS (Vite content-hashes filenames so cache-busting is built in), bumped SW cache version, and added `Cache-Control: no-cache` to the `sw.js` endpoint so browsers always pick up new service worker versions immediately. The SpoolBuddy kiosk now skips SW registration entirely and unregisters any existing SW — a touchscreen kiosk has no use for offline caching and it was the main source of stale frontend issues after updates.
 - **SpoolBuddy Kiosk Starts Before Network Is Ready** — On fresh installs, the kiosk browser launched before the network was fully up, showing a connection error for 10-15 seconds until connectivity was restored. The getty@tty1 autologin override now waits for `network-online.target` so Chromium has connectivity when it starts.
 - **SpoolBuddy Update UI Stale After Restart** — After a SpoolBuddy update, the UI permanently showed the old version and "update available" because: (1) the SSH update set status to `"complete"` after the daemon had already re-registered, overwriting the cleared state; (2) the kiosk restart navigated away from the updates page; (3) query cache served stale data. Fixed by letting daemon re-registration clear all update status, removing the kiosk restart in favor of a frontend-driven `window.location.reload()` triggered via WebSocket when the daemon comes back online, and adding proper loading states to Check/Force Update buttons.
-- **Virtual Printer Proxy A1 Printing Fails** ([#757](https://github.com/maziggy/bambuddy/issues/757)) — BambuStudio could not send prints to A1 (and potentially P1S) virtual printers in proxy mode. The slicer connects to undocumented proprietary ports 2024-2026 on these models, which the proxy was not forwarding, causing BambuStudio to show an access code dialog instead of printing. Added transparent TCP pass-through proxying for ports 2024-2026. These ports are silently ignored on models that don't use them (X1C, H2C, P2S). Also added ports 2024-2026 to the docker-compose.yml bridge-mode port mapping. Reported by @Utility9298.
-- **Spool Assignment on Empty AMS Slots** ([#784](https://github.com/maziggy/bambuddy/issues/784)) — Empty AMS slots (no physical spool detected) showed "Assign Spool" and "Configure" buttons in the hover popup. Assigning a spool to an empty slot created a stuck state because no "Unassign" button is available for empty slots. Truly empty slots now hide both buttons, while slots with a spool inserted but filament not loaded still show configure/assign. Also fixed stale AMS slot data on H2D and other printers that only send `{id, state}` in incremental MQTT updates — filament load/unload transitions now update in real-time without requiring a reconnect. Reported by @RosdasHH.

 - **Spoolman Sidebar Opens Root URL Instead of Spool Page** — When Spoolman is enabled, clicking the Filament sidebar item embedded Spoolman at its root URL instead of the spool management page. The iframe now navigates to `<spoolman_url>/spool`.
-- **Log Flood: "State is FINISH but completion NOT triggered"** ([#790](https://github.com/maziggy/bambuddy/issues/790)) — A diagnostic log message introduced in 0.2.2.1 fired on every MQTT update while a printer sat in FINISH or FAILED state, flooding logs with thousands of lines per minute in printer farms. Fixed by only logging once on the initial state transition, and marking `_completion_triggered = True` when a terminal state is first seen without a prior RUNNING state so the flag is clean for the next print cycle.

-- **H2D External Spool Print Fails With "Failed to get AMS mapping table"** ([#797](https://github.com/maziggy/bambuddy/issues/797)) — Printing from an external spool on H2D (and H2D Pro) through Bambuddy failed with `0700_8012 "Failed to get AMS mapping table"`, while the same print worked fine from BambuStudio. Bambuddy was passing raw virtual tray IDs (254/255) in the flat `ams_mapping` array, but BambuStudio converts these to -1 and relies on `ams_mapping2` for external spool routing. The H2D firmware rejects raw 254/255 in the flat array. Also fixed the `ams_mapping2` format for external trays — each virtual tray is its own AMS unit with `slot_id: 0`, not a shared unit differentiated by slot. Reported by @Lukas-ESG.
+- **Log Flood: "State is FINISH but completion NOT triggered"** ([#790](https://github.com/maziggy/bambuddy/issues/790)) — A diagnostic log message introduced in 0.2.2.1 fired on every MQTT update while a printer sat in FINISH or FAILED state, flooding logs with thousands of lines per minute in printer farms. Fixed by only logging once on the initial state transition, and marking `_completion_triggered = True` when a terminal state is first seen without a prior RUNNING state so the flag is clean for the next print cycle.

 - **SpoolBuddy Scale First Reading Always Wrong** — The NAU7802 ADC always returns a stale max-scale value (`0x7FFFFF`) on its first conversion after power-up, which polluted the moving average and made the initial weight report wildly inaccurate. Fixed by flushing the first reading during `init()` so all subsequent reads return valid data. Also extracted both hardware drivers out of diagnostic scripts into proper modules — the NAU7802 scale driver from `scripts/scale_diag.py` into `daemon/nau7802.py`, and the PN5180 NFC driver from `scripts/read_tag.py` into `daemon/pn5180.py`. The production daemon was importing driver classes from test scripts since the original SpoolBuddy commit. Removed the now-unnecessary `sys.path` hack from `main.py`.
-- **ffmpeg Process Leak Causing Memory Growth** ([#776](https://github.com/maziggy/bambuddy/issues/776)) — Camera stream ffmpeg processes accumulated over time, consuming several GB of RAM. When a user closed the camera viewer, the frontend sent a stop signal that killed the ffmpeg process, but the backend stream generator interpreted the dead process as a dropped connection and respawned ffmpeg — up to 30 reconnection attempts per stream. The orphan cleanup couldn't catch these because they were tracked as "active". Fixed by signaling the generator's disconnect event from the stop endpoint before killing the process, checking for stream removal before reconnecting, and tracking frame timestamps per-stream instead of per-printer so stale detection works correctly when multiple streams exist.
