maziggy ed232718f5 fix(prints): connected-edge reconciliation closes the missed-PRINT-COMPLETE loop behind smart-plug ghost prints (#1542 follow-up)
Reporter ran a fresh trace after the doubled-extension fix landed and
  found a distinct second cause behind his ghost prints, hitting 4-of-4
  of his A1s. Timeline:

    22:50 PRINT START
    ...print runs all night...
    23:13 / 00:47 / 09:35 MQTT disconnects (A1 keepalives are unstable)
    print finishes during one of those disconnect windows → PRINT COMPLETE
      is never observed
    smart plug detects idle → cuts power
    power resumes for the next scheduled print → firmware auto-replays the
      leftover .3mf from the SD card
    09:46 Bambuddy reconnects to a fresh PRINT START for the ghost

  The existing IDLE-after-RUNNING completion check at
  backend/app/services/bambu_mqtt.py:3022 was meant to catch the simple
  disconnect-then-finish case via `_previous_gcode_state` preserved across
  reconnects, but with multiple disconnect/reconnect cycles + a smart-plug
  power-off that Bambuddy can't distinguish from any other transient drop,
  the IDLE window that branch needs simply never reaches it. The SD .3mf
  lingers, the firmware ghost-replays every power cycle, and the loop
  repeats.

  Fix: new connected-edge reconciliation pass.

  * `_is_active_archive_stale(archive, state)` — pure decision function
    with three triggers:
      (1) printer state is terminal (IDLE / FINISH / FAILED)
      (2) printer running with a different `subtask_id` than the archive —
          Bambu firmware mints a fresh subtask_id for each print including
          the ghost replay, so a mismatch is unambiguous
      (3) printer running but `subtask_name` is empty — printer doesn't
          know what it's running, archive reference is broken
    Conservative on PAUSE / PREPARE / SLICING and on RUNNING with matching
    subtask. False-positive cost = one misreported "aborted" status that
    the next real PRINT COMPLETE would have overwritten anyway. False-
    negative cost = the ghost-print loop.

  * `reconcile_stale_active_prints(printer_id)` — queries archives in
    `status="printing"` for the printer, runs the decision function, and
    synthesises `on_print_complete(status="aborted", _reconciled=True)`
    for each stale match. Reuses the existing PRINT COMPLETE chain (SD
    cleanup, status update, usage tracker, notifications) — no reimplem-
    entation. Per-archive try/except so one failure doesn't block the
    rest. Returns 0 when status is None / disconnected — the connected
    edge is the only legitimate trigger.

  * `on_printer_status_change` now runs a connected-edge check at the
    start. New `_printer_reconciled_since_connect: dict[int, bool]`
    tracker flips False → True on the first connected status update for
    this connection and back to False on disconnect, so reconciliation
    fires exactly once per (re)connection. The flag is set BEFORE the
    task is spawned so concurrent status updates within the same
    connection don't re-trigger it (no await between check and set,
    asyncio guarantees atomicity). The reconciliation runs as
    `asyncio.create_task` so the hot WebSocket dedup / broadcast path
    isn't blocked.

  * Single handler covers both startup and reconnect — when the first
    MQTT connection completes after startup the printer pushes status,
    the connected edge fires, reconciliation runs. No separate startup
    hook needed.

  Idempotency: when the existing #3022 branch DOES fire on a clean
  disconnect-then-IDLE-on-reconnect, it lands `archive.status` to terminal
  synchronously. The async-scheduled reconciliation then queries
  `WHERE status="printing"` and finds 0 rows → no-op. The narrow race
  where reconcile's query lands between a real on_print_complete's
  archive update and its archive lookup produces at most a duplicate
  notification (no double SD-cleanup since FTP delete on a missing file
  is a no-op 550).

  Ghost-print collateral worth being explicit about: if the ghost is
  already running when reconciliation fires, the synthesised SD-cleanup
  hits 550-file-locked (same root cause as the #1542 first case). The
  cleanup retries 3× then logs "lingering". The ghost runs to completion,
  its own end-of-print cleanup deletes the file, the next power cycle
  has nothing to replay, the loop breaks. A perfect cancel would require
  a `print_stop` MQTT command to the printer mid-ghost — invasive,
  explicitly out of scope.

maziggy 7a7dfed81a fix(archives): resolve raw_data wrapper in fallback-archive filament extraction (#1533 follow-up)
Reporter updated to 0.2.5b1 expecting the #1533 fix to populate filament
  fields on his P2S virtual-printer prints when the .3mf is locked. His
  support bundle showed Bambuddy still creating fallback archives with NULL
  filament fields even though the print-start log line proved AMS-0-T0 had
  PETG loaded at the moment the helper should have read it
  (`AMS 0: T0(type=PETG, color=FFFFFFFF, ...)`).

  Cause: the #1533 helper `_extract_filament_data_from_mqtt(data)` in
  backend/app/main.py only looked at `data["ams"]`, but the dict that
  on_print_start actually receives at runtime is the wrapper shape
  `{"filename", "subtask_name", "remaining_time", "raw_data": <mqtt>,
  "ams_mapping"}` that backend/app/services/bambu_mqtt.py:2971-2980
  constructs. So `data["ams"]` was undefined on every real call and the
  helper silently returned `{}`, leaving the fallback archive's
  filament_type / filament_color NULL — the exact regression the original
  fix was meant to close. The 15 unit tests that shipped with #1533 all
  passed the bare inner shape directly and never exercised the callback
  wiring, so the regression slipped through a green build. Surrounding code
  in the same fallback path (main.py:2064, 2674) already reads
  `data.get("raw_data")` — the original hunk was the outlier that forgot
  the wrapper.

  Fix: helper now resolves `data["raw_data"]["ams"]` first (the callback
  shape) and only falls back to `data["ams"]` when the wrapper isn't
  present, preserving the inner-shape callers from the existing tests.
  Defensive against a non-dict `raw_data` (e.g. partial MQTT decode
  failure) falling through to the inner lookup instead of crashing.

  Tests: 5 new in `TestOnPrintStartCallbackShape` in
  test_fallback_archive_mqtt_filament.py — wrapper payload with ams_mapping
  resolves to the inner AMS state; wrapper without ams_mapping lists all
  loaded slots; the existing inner-shape callers still work after the
  additive wrapper lookup; missing raw_data returns `{}` instead of
  raising; junk raw_data (string) doesn't shadow a present inner `ams`.
  Existing 15 inner-shape tests untouched and green. Full 5378-test
  backend suite green; backend ruff clean.

  What this does NOT fix: per-filament gram usage still needs the actual
  .3mf — the printer locks it during print (P-line firmware behaviour,
  not a Bambuddy bug), and the existing 19 FTP candidate paths +
  directory probes are expected to 550 in that window. Per-print filament
  type and colour are the data point the reporter explicitly called out
  as load-bearing for AMS-expansion planning at his maker space, so this
  is what moves the needle.

maziggy 9347921378 fix(inventory): drop profile-only mismatch popup and clarify reconfigure intent (#1552)
Reporter assigned a spool to a slot whose stored slicer profile differed
  from the new spool's, got the Cancel / Assign Anyway popup, and was under
  the impression that confirming the popup just linked the spool in
  Bambuddy's DB without pushing the new profile to the AMS — i.e. that he
  then had to manually open Configure AMS Slot to fix it. The auto-push has
  actually been in place since the assign route existed:
  backend/app/api/routes/inventory.py::assign_spool calls
  apply_spool_to_slot_via_mqtt after upserting the SpoolAssignment row,
  which publishes ams_filament_setting + extrusion_cali_sel over MQTT, and
  backend/app/api/routes/spoolman_inventory.py::assign_spoolman_slot does
  the same for the Spoolman backend. The only short-circuit is when
  firmware reports the slot explicitly empty (tray_state in {9, 10}), in
  which case main.py::on_ams_change deferred-replays the configure once a
  spool appears. So the popup was friction without revealing what it did.

  Two changes:

  - frontend/src/components/AssignSpoolModal.tsx and
    spoolbuddy/AssignToAmsModal.tsx: profile-only mismatch no longer
    fires the popup. The condition becomes
    `if (materialMatchResult !== 'exact')` instead of
    `materialMatchResult !== 'exact' || !profileMatches`. The 'profile'
    member is dropped from the mismatchType union and its standalone
    branch in each popup render body is removed as dead code. Material
    mismatch still warns — Bambu firmware can refuse the print when the
    type is wrong.

  - Every firing warning (material, partial, material+profile,
    partial+profile) now appends one line via a new
    inventory.assignReconfigureNote i18n key:
    "The AMS slot will be reconfigured to use the spool's profile."
    Real translations across all 9 locales per
    feedback_translate_dont_fallback; parity script clean at 4999
    leaves per locale.

maziggy 632334953c fix(inventory): support transparent / clear filament end-to-end (#1545)
Reporter wanted to select a transparent filament colour in the spool
  editor; CMW-ISS confirmed on v0.2.5b1 that AMS-detected transparent
  spools were silently labelled "Black" in the filament-mapping dropdown
  because the colour name resolver dropped the alpha byte and the underlying
  RGB 000000 HSL-bucketed to "Black". Spoolman already supported 8-digit
  hex; the built-in inventory didn't.

  Eight collapsing sites fixed together so transparent reaches the user
  intact:

  - frontend/src/utils/colors.ts: hexToColorName / getColorName /
    resolveSpoolColorName / isLightColor short-circuit to "Clear" for
    alpha=00 before HSL bucketing or catalog lookup
  - frontend/src/utils/amsHelpers.ts::normalizeColor preserves the alpha
    byte when alpha < FF (normalizeColorForCompare unchanged so type/colour
    matching is unaffected)
  - frontend/src/components/spool-form/constants.ts: new
    { name: 'Clear', hex: '00000000' } preset in QUICK_COLORS
  - frontend/src/components/spool-form/ColorSection.tsx: hex draft accepts
    0-8 chars, commits at 6 (+FF) or 8 verbatim; blur pads 7-char to 8;
    selectColor passes 6-char as +FF / 8-char verbatim; isSelected matches
    on full rgba; swatch buttons paint a checkerboard for alpha=00
  - backend/app/api/routes/printers.py::get_available_filaments preserves
    the full rgba on both AMS and vt_tray branches (6-char dedup key
    unchanged)
  - backend/app/services/spoolman.py::parse_ams_tray drops the silent
    00000000 -> F5E6D3FF cream rewrite — the swatch renderer paints a
    checkerboard underlay for alpha < FF already (added in #1154), so the
    rewrite was hidden technical debt that made every AMS-detected
    transparent spool land in inventory as cream
  - backend/app/services/spool_tag_matcher.py::create_spool_from_tray
    short-circuits the colour-catalog lookup for alpha=00 and stores
    color_name="Clear" directly — otherwise an RFID-tagged transparent
    Bambu spool would resolve against the #000000 catalog row (or "Black"
    via the HSL fallback) before the frontend's resolver ever saw it
  - Two shared helpers in utils/colors.ts — getSwatchStyle(rgba) (style
    object: checkerboard for alpha=00) and spoolColorString(rgba)
    (8-char hex string for SVG fill) — applied to every simple-swatch
    site that would otherwise have rendered Clear spools as solid black:
    LabelTemplatePickerModal, SpoolBuddyInventoryPage (SpoolCircle + dot),
    SpoolBuddyAmsPage (both branches), SpoolBuddyWriteTagPage (4 sites),
    ForecastPanel, AssignToAmsModal, AssignSpoolModal (both branches),
    InventorySpoolInfoCard, TagDetectedModal, SpoolInfoCard, LinkSpoolModal,
    and the FilamentSwatch tooltip title fallback

  Intentionally NOT changed: native <input type="color"> keeps 6-char hex
  (can't pick alpha; onChange still emits +FF, correct); Spoolman's
  _find_or_create_filament strips alpha (Spoolman catalog is 6-char only);
  print_scheduler colour matching strips alpha (auto-mapping treats Clear
  as Black for slot compatibility); label_renderer prints "#RRGGBB" on the
  physical label (printers can't print transparency, swatch fill via
  _color_from_hex still honours alpha).

maziggy b663605318 fix(virtual-printer): honour client-negotiated MQTT keepalive instead of hardcoded 60s (#1548)
OrcaSlicer connects, exchanges pushall + get_version, then sits idle waiting
  for status pushes from the (virtual) printer. The VP MQTT server's read
  loop used `asyncio.wait_for(reader.read(1), timeout=60)` regardless of what
  the client negotiated, and `_handle_connect` explicitly skipped the
  keepalive field in the CONNECT payload, so every idle slicer connection was
  torn down at exactly 60s.

  - Parse the 2-byte big-endian keepalive from CONNECT; return it from
    _handle_connect alongside the auth bool.
  - Use 1.5x the negotiated keepalive as the per-packet read timeout per
    MQTT spec sec 4.4. Treat keep_alive == 0 as no timeout (spec sec 3.1.2.10).
  - Retain the 60s default for the initial read before CONNECT arrives, so
    a TCP-connect-without-CONNECT still gets reaped.
  - 7 new tests: 4 unit-level for the parser (success, opt-out=0, auth-fail
    tuple shape, malformed CONNECT) + 3 integration-style for the read loop
    (long keepalive survives the old 60s mark, short keepalive closes idle
    in ~3s, PINGREQ resets the window so DISCONNECT decides the exit).

maziggy 6d316c5593 fix(dispatch): align SD cleanup with upload path so doubled-extension library rows don't leave ghost prints (#1542)
A library row with archive.filename "Cube (1).gcode.3mf.gcode.3mf" uploaded
  to /Cube_(1).gcode.3mf.3mf (single-iteration strip + append). Post-print
  cleanup looked at /Cube_(1).3mf and /Cube_(1).gcode (subtask_name + ext),
  missed the on-card file, and A1 firmware re-ran it on next power-on.

  - New derive_remote_filename() helper in backend/app/utils/filename.py:
    iterative strip of .gcode.3mf/.3mf suffixes, append single .3mf,
    space->underscore. isinstance() guard raises TypeError on non-str
    input rather than entering the strip loop with a duck-typed
    object that returns truthy sentinels from endswith.
  - Three previously-duplicated upload sites (background_dispatch reprint +
    library, print_scheduler queue) now share the helper.
  - SD cleanup fetches archive.filename and tries the derived path first,
    with the legacy subtask_name + ext paths kept as fallbacks.
  - 10 new unit tests pin the reproducer + edge cases (doubled .gcode.3mf,
    doubled .3mf, raw .gcode preserved, idempotence, Unicode, plus the
    type guard against MagicMock / None / int inputs).

maziggy 2241924312 fix(library): reject FAT32-illegal filename chars at rename/upload/queue time (#1540)
Bambu printer SD cards are FAT32/exFAT, which forbids < > : " / \ | ? *
  plus control chars and trailing dots/spaces. Library rename only blocked
  path separators, so a name like L|R.3mf was accepted and only failed
  later at FTP upload with 553 Could not create file - far from the rename
  action that caused it. Bambu Studio refuses these names in its save
  dialog; Bambuddy now does the same.

  New backend/app/utils/filename.py centralises validation. Wired into
  update_file, upload_file, print_library_file, and queue add. Existing
  rows with bad names are left alone (no silent rewrite of user data);
  users get an actionable 400 pointing at rename.

  Frontend rename modal mirrors the same set client-side with inline error.
  New fileManager.invalidFilenameChar i18n key translated across all 9
  locales. 26 new tests in test_filename_validation.py.

GitHub forces Node-20 actions to run on Node 24 starting 2026-06-02 and
  removes Node 20 from the runner on 2026-09-16. Bumping each action to
  its first Node-24 major now gets us ahead of both deadlines and silences
  the deprecation warnings already firing in every CI run.

  Bumps (across ci.yml, security.yml, codeql.yml, auto-label-area.yml,

  - docker/setup-buildx      v3 -> v4
  - docker/build-push        v5 -> v7

  Verified each major's breaking-change notes against our usage:
  - setup-node v6 limits auto-cache to npm only; we already pass
    cache: 'npm' explicitly, so nothing changes.
  - github-script v9 drops require('@actions/github'); none of our

  - setup-buildx v4 removes deprecated inputs; we call it with no
    inputs.
  - build-push v6 enables build summaries by default; informational,
    can disable via DOCKER_BUILD_SUMMARY=false env if it gets noisy.

  codeql-action stays on v4 (already runs on Node 24). Trivy and
  github-repo-stats are Docker actions and aren't affected by the
  Node-20 deprecation.

maziggy c8881c165a chore(deps): pin fastapi<0.136.0 to dodge MAL-2026-4750
Amazon Inspector flagged fastapi 0.136.x for shipping an undocumented
  `fastar>=0.9.0` dep in its [standard] extras group. `fastar` is a
  Rust-tar binding package, no plausible reason for a web framework to
  depend on it. Even if `fastar` is benign today, the advisory's
  "namespace-abuse vector" framing is valid — whoever controls the
  fastar PyPI namespace gains code execution at install time across
  every fastapi[standard] install.

  Bambuddy doesn't request [standard] so we don't pull fastar in
  practice, but pip-audit flags the fastapi package itself and breaks
  CI. Hold to 0.135.x (last clean release line) until upstream removes
  the dep.

maziggy c42e923e4c fix(archives): MQTT-derived filament type/color on fallback archives (#1533)
When the source .3mf can't be downloaded at print start (P1S/A1/P2S
  firmwares lock the file mid-print), main.py creates a fallback
  PrintArchive with file_path="" and every filament field NULL — even
  though the MQTT payload already has the AMS state and the slicer's
  slot-per-print-filament mapping (data["ams"]["ams"] and
  data["ams_mapping"]).

  New _extract_filament_data_from_mqtt(data, ams_mapping) builds a
  {global_tray_id: (type, color)} map from the AMS units, then narrows
  to slots referenced by ams_mapping (slicer order preserved, -1 VT-tray
  sentinels skipped) or falls back to every loaded slot when no mapping
  is present. Returns comma-separated filament_type and filament_color
  matching the 3MF-extraction shape, so the inventory page, Quick Stats
  rollup, and len(filament_type.split(",")) per-print count behave
  identically for fallback rows.

  The constructor at the fallback site now passes the resulting values
  into the PrintArchive row.

  This does NOT recover per-filament gram usage — that needs the .3mf's
  slice_info.config or a deeper layer-delta integration via usage_tracker.
  The reporter (maker-space lead evaluating Bambuddy partly for AMS
  expansion planning) asked specifically for "the number of filaments
  used", which is what this gives them.

  15 unit tests cover empty/malformed payloads, the no-mapping path,
  mapping filtering and reordering, VT-tray sentinels, dual-AMS global
  ids, column-limit truncation, and defensive garbage handling.

maziggy d0ff6f7dc1 fix(spoolbuddy): tare banner now resolves to complete or timed-out (#1536)
The TARE button on Settings → Scale set a "Tare command sent. Waiting
  for device..." banner with no mechanism to clear it. The daemon writes
  back through /calibration/set-tare which stamps last_calibrated_at on
  the device row, but handleTare was set-and-forget — the banner stayed
  forever. The "Calibration complete!" success banner had the same shape.

  Snapshot last_calibrated_at when TARE is pressed, set an awaiting state,
  invalidate the device-list query every 1s while waiting (so detection
  responds within ~1s, not the 10s background poll), and when the snapshot
  advances flip the banner to "Tare complete!" with a 3s auto-dismiss. A
  15s timeout falls open to "Tare timed out — is the SpoolBuddy daemon
  running?" so a dead daemon doesn't trap the user on the spinner. The
  calibration-complete and calibration-failed banners now share the same
  auto-dismiss helper.

maziggy 4343bd60b1 fix(notifications): honest UA + Cloudflare-challenge detection on ntfy (#1534)
The notification service's httpx client was the only outbound client in
  the codebase still leaking python-httpx/<version> as User-Agent; all
  other clients identify as Bambuddy/1.0 since the May 2026 compliance
  pass. Bring it in line.

  The reporter's ntfy server was behind a Cloudflare Tunnel and CF returned
  its JS challenge page (Just a moment...) to every API request — confirmed
  by reproducing the same 403 with curl. Cloudflare can't be solved from a
  backend, so add detection for the challenge shape (Server: cloudflare or
  cf-mitigated header, or <!DOCTYPE html>...Just a moment... body) and
  return an actionable error message that points at the real fix on the
  user's CF side instead of dumping the raw HTML.

  Normal 403s (auth failures with plain text bodies) still surface the
  original body so genuine errors stay debuggable.

maziggy e9beb1e8fc fix(archives): handle fallback archives in source-3MF upload (#1531)
Archives created from prints Bambuddy didn't archive (cloud / Handy /
  SD-card prints) carry file_path="". The two source-upload routes
  computed the destination as (base_dir / archive.file_path).parent /
  "source", which collapsed to base_dir.parent / "source" for fallback
  rows — sending the file to /app/source/ (outside the data volume,
  orphaned on container restart) and raising 500 on the final
  relative_to.

  Centralise the destination math in _resolve_source_3mf_path. Normal
  archives keep the <archive>/source/<filename> layout. Fallback
  archives land at <base_dir>/archive/no_source/<id>/<filename>, which
  stays inside the data volume and is addressable by every existing
  read site. The helper also asserts the resolved directory is under
  base_dir.resolve() so a corrupted row fails with a clear message
  instead of writing outside the volume.

  Both upload routes (upload_source_3mf and upload_source_3mf_by_name)
  now route through the helper. Two regression tests in
  TestUploadSourceThreeMF pin both branches.

maziggy 4387a09162 fix(spoolbuddy): route weight sync by inventory mode exclusively (#1530)
POST /spoolbuddy/scale/update-spool-weight tried the local DB first
  and only fell back to Spoolman on a local miss. Combined with
  nfc/tag-scanned's post-#1119 always-Spoolman routing, a stale local
  Spool row sharing a numeric id with a Spoolman spool would absorb
  the sync silently while the Spoolman row stayed unchanged.

  Mirror the routing already used by nfc/tag-scanned: pick the branch
  via _get_spoolman_client_or_none() and never cross. Local mode now
  returns 404 on a local miss instead of falling through.

  New TestUpdateSpoolWeightSpoolman.test_stale_local_row_does_not_shadow_spoolman
  asserts both directions: Spoolman gets the update, the colliding
  local row's weight_used and last_scale_weight are untouched.

maziggy 554a73070f fix(maintenance): paused prints no longer accumulate runtime hours (#1521)
PAUSE counted toward runtime_seconds equally with RUNNING, inflating
  hours-based maintenance thresholds (rod lube, belt check, nozzle clean)
  by however long overnight or extended pauses lasted. Maintenance items
  track mechanical wear, which is zero while paused, so the predicate
  now excludes PAUSE. Field-comment and docstring trail across main.py /
  models/printer.py / maintenance.py updated to match. Existing
  runtime_seconds values cannot be retroactively split — only future
  accumulation is fixed.

  Adds 3 regression tests pinning PAUSE non-accumulation, RUNNING
  accumulation, and the FINISH state's last_runtime_update clear
  (prevents idle-time back-bill when the printer next goes RUNNING).

maziggy 4cce575bcc fix(stats): cancelled bucket icon now uses semantic warning token (orange) (#1390 follow-up)
Reporter flagged that the new Cancelled row's Ban icon rendered colourless
  while Successful and Failed used green/red icons in the same widget. Switch
  the Cancelled icon to text-status-warning (amber-500) so all three rows now
  use semantic status tokens consistently, and the colour matches the orange
  Archives + notification badges already use for cancelled status.

maziggy 5d248e16ba chore(triage): tighten bug-report template + add Area dropdown to cut invalid-issue load
170 issues have been closed with the `invalid` label (61 of them in
  the last 30 days alone — ~1 in 5 of all closed issues), almost always
  because the reporter hadn't run the in-app Connection Diagnostic or
  checked the documented troubleshooting page. The Connection Diagnostic
  shipped weeks ago but the bug-report form let people skip it: the
  "I ran it" checkbox was `required: false` and the Support Package
  field was optional. Tighten both.

  Form changes (.github/ISSUE_TEMPLATE/bug_report.yml):

  - Connection Diagnostic checkbox: required: false → true
  - Support Package field: required: false → true ("drag the .zip
    or explain why you cannot attach one")
  - New required textarea "Troubleshooting steps already taken" —
    forces the reporter to type WHAT they tried and WHICH wiki pages
    they checked before submitting. Empty answers can't submit.
  - Pre-form intro spells out the search → wiki → diagnostic →
    support package sequence and cites the 1-in-5 stat
  - Final-checks list grew from one to three required confirmations
    (searched issues + checked troubleshooting wiki + ran Connection
    Diagnostic for any connection/printing/camera issue)

  Bug categorization (the gap that motivated this):

  - Old `Component` dropdown was Bambuddy / SpoolBuddy / Both — no
    area triage signal
  - Replaced with two required dropdowns:
    - Product: Bambuddy / SpoolBuddy
    - Area: 15 options covering the actual feature surface +
      Other / not sure
  - Auto-label workflow (.github/workflows/auto-label-area.yml)
    reads the Area dropdown from the rendered issue body on
    open/edit and applies the matching area:* label. Tolerant of
    CRLF and the _No response_ placeholder, won't re-add on edit
    re-fires, warns on unknown Area values

  Maintainer hand-off — labels must exist BEFORE the workflow runs,
  since github-script's addLabels throws on missing labels. Create the
  16 labels (15 area:* + 1 area:unsorted) once via the `gh label create`
  commands captured in CHANGELOG / commit context.

  OS dropdown left untouched (Docker stays — per Martin).

maziggy 1e734fb7c6 fix(stats): cancelled prints get their own bucket; gauge denominator excludes them (#1390 follow-up)
Reporter (@IndividualGhost1905) saw Total: 20 / Success: 18 / Failed: 1
  and asked where the 20th print went. The Quick Stats endpoint counted
  status == "completed" → Successful and status == "failed" → Failed, but
  used a raw count(*) for Total Prints, so the four other PrintLogEntry
  statuses (aborted, stopped, cancelled, skipped) silently inflated the
  total without showing up in any breakdown row. The earlier #1390 round
  had committed a test locking in this exact behaviour
  ("uses total_prints as denominator so cancelled/stopped events count"),
  which was wrong: it conflated user intent with print quality.

  Three-bucket classification, applied across the whole stats surface
  and matching how the rest of the codebase already groups statuses
  (main.py:430, 1729; failure_analysis status filter):

    successful = completed
    failed     = failed + aborted    (printer-detected quality failures)
    cancelled  = stopped + cancelled + skipped  (user/queue stopped)

  Quick Stats endpoint returns the new cancelled_prints field;
  ArchiveStats.cancelled_prints defaults to 0 so older fixtures still
  parse. SuccessRateWidget gauge now divides by successful + failed
  only — a cancelled roll no longer drags the gauge down — and a
  Cancelled row appears in the breakdown so the missing prints don't
  silently vanish from Total Prints.

  Failure Analysis service applies the same denominator fix to both
  the headline failure_rate and the per-week trend, so a week with
  several cancellations and zero failures reads as 0% rather than
  a misleading "failed / total".

  i18n: new stats.cancelled key in all 9 locales with real
  translations (no English fallback), parity script clean.

  Tests: the existing 'uses total_prints as denominator' assertion
  is inverted to assert the new behaviour (40 / 20 / 35 → 67% gauge,
  Cancelled: 35 visible). The unchanged-display path (140 / 10 / 0
  → 93%) still holds since 140 / (140 + 10) = 93.33% rounds the
  same. 33 StatsPage tests + 6 backend stats/failure tests green.

maziggy c0129ef93f chore(docker): silence Trivy DS-0026 on Dockerfile.test via HEALTHCHECK NONE
Trivy raised DS-0026 ("No HEALTHCHECK defined") against Dockerfile.test
  on every run of the security workflow. The test image is a one-shot
  pytest runner — there's no service to probe, so any HEALTHCHECK we
  invented would be cargo-cult noise that fires once and means nothing.

  HEALTHCHECK NONE is the documented Docker directive to explicitly opt
  out of any inherited HEALTHCHECK and is the way Trivy itself expects
  projects to signal "this image is intentionally not a long-running
  service." Adding it closes code-scanning alert #813 cleanly.

  Note: the perl-base CVE-2026-8376 alert (#811) is left open for now
  and dismissed in the GitHub UI as "Won't fix - no upstream patch"
  because Debian Trixie has not yet shipped a fixed perl-base; the
  patched build will land automatically on the next base-image refresh.

maziggy 66fea70564 ci(docker): full backend suite in Docker, 4-way matrix shard, GHA cache backend
Earlier patch trimmed the duplicate unit-test re-run from docker-test
  to drop a 5-10 min job that wasn't adding coverage. But "wasn't adding
  coverage" only holds for pure-logic tests — system-touching tests
  (ffmpeg version probes, ftp clients, subprocess shell-outs, locale/
  timezone-sensitive assertions, paths) genuinely can pass on the GHA
  host and fail in python:3.13-slim. Curation via a `docker_env`
  marker is fragile (new tests get forgotten); gating on `main` only
  defers the cost without removing it.

  Instead, run the full backend suite IN Docker on every PR but make
  it fast:

  - New docker-backend-tests job runs the same 4-way pytest-split
    matrix as the host backend-tests, just inside the test image.
  - docker/setup-buildx-action + docker/build-push-action@v5 with
    cache-from/cache-to: type=gha,scope=backend-test persist the
    BuildKit cache (pip-install layer included) across CI runs and
    across the 4 sibling shards. Cold build is ~150s/shard; warm
    build drops to ~10s/shard.
  - fail-fast: false so a single failing shard surfaces the rest's
    output too.

  Total CI wall-clock for a PR push is now gated by docker-test (the
  image-build + integration HTTP smoke + integration test suite job)
  at ~3 min, not by the unit-test re-run anymore.

  The earlier ci.yml step that ran `docker compose run --rm
  backend-test` synchronously in the docker-test job stays removed —
  the new docker-backend-tests matrix covers the same ground and is
  much faster.

  bambuddy-frontend-test images that the host-side backend-tests and
  frontend-tests jobs had already run. Same test code, same Python

  installs. On 2-vCPU GHA runners that re-run added 5-10 min of

maziggy e377b4aaa9 ci(docker): drop -v, -n auto instead of -n 30, pip cache mount
Three things were making the Docker test runs noisier and slower than
  they needed to be:

  1. -v was hardcoded in Dockerfile.test:35 CMD and in docker-compose.
     test.yml's integration-test-runner command. The ci.yml change to
     drop -v from the bare pytest call missed both — Docker runs use
     the image's CMD, not the workflow's.

  2. -n 30 was hardcoded as the xdist worker count. On a 2-vCPU CI box
     that's 30 Python processes fighting over 2 cores — mostly IPC and
     import-thrash overhead. -n auto adapts to the host: 2 on CI, 30
     on a 30-core dev box. Same final-result throughput on the dev
     box, much better on small runners.

  3. pip install had --no-cache-dir and no BuildKit cache mount, so
     every Docker build re-fetched ~50 packages from PyPI (~60-90s
     on a cold pip cache). Adding `RUN --mount=type=cache,target=
     /root/.cache/pip` (with the `# syntax=docker/dockerfile:1.7`
     directive that enables it) makes subsequent builds re-use the
     download cache so they only do install work, ~5s instead of
     ~90s. DOCKER_BUILDKIT=1 is already exported in test_docker.sh
     and is the GHA default since runner image 2023, so the cache
     mount is always honoured.

  Verified locally: Docker build is 19s warm (was ~90s cold each
  time), test run is 102s with 5287 passed / 1 skipped (the
  by-design spoolbuddy importorskip) — clean output, no [gwN]
  worker spam, no "created: 30/30 workers" startup line.

  GHA-side per-run cold-build slowness still happens because GHA
  runners are ephemeral; a follow-up using docker/build-push-action
  with type=gha cache backend would persist the BuildKit cache
  across CI runs but that's a bigger workflow change.

     on a cold pip cache). Adding `RUN --mount=type=cache,target=
     /root/.cache/pip` (with the `# syntax=docker/dockerfile:1.7`
     directive that enables it) makes subsequent builds re-use the
     download cache so they only do install work, ~5s instead of
     ~90s. DOCKER_BUILDKIT=1 is already exported in test_docker.sh
     and is the GHA default since runner image 2023, so the cache
     mount is always honoured.

  Verified locally: Docker build is 19s warm (was ~90s cold each
  time), test run is 102s with 5287 passed / 1 skipped (the
  by-design spoolbuddy importorskip) — clean output, no [gwN]
  worker spam, no "created: 30/30 workers" startup line.

  GHA-side per-run cold-build slowness still happens because GHA
  runners are ephemeral; a follow-up using docker/build-push-action
  with type=gha cache backend would persist the BuildKit cache
  across CI runs but that's a bigger workflow change.

maziggy fdf818e54c fix(test): stop sys.modules-deleting backend.app.main in test_code_quality
+ ci: shard backend tests 4-way + drop -v for ~3.5x wall-clock speedup

  Root cause of the 4 CI failures on PR #1514 (all in
  test_print_start_assigns_printer_id_to_vp_archive.py +
  test_timelapse_baseline_restart_recovery.py): test_all_modules_importable
  in test_code_quality.py was deleting backend.app.main from sys.modules
  and re-importing it via importlib.import_module. That created NEW
  module-level dicts (_timelapse_baselines, _expected_prints,
  _active_prints, …) and re-ran root_logger.addHandler — hence the
  duplicate log lines at the same microsecond in captured stderr.

  Any sibling test that bound those names via "from backend.app.main
  import _timelapse_baselines" before the reimport now held a reference
  to the OLD dict; production code (reached via "from backend.app.main
  import on_print_start") resolved the symbol through the NEW module
  instance. Production mutated the new dict, the test read the old one,
  the assertion saw None / un-mutated mock_archive.

  Locally with -n 30, xdist load-balanced test_code_quality.py to a
  different worker process so the collision never happened (which is
  why the suite was green for me). CI's -n auto = -n 2 on ubuntu-latest
  made the collision deterministic.

  Fix: drop the "del sys.modules[name]" step. importlib.import_module
  already returns the cached module if cached, or runs the import
  machinery if not — either way, any import-time error surfaces. The
  "fresh import" framing was theatre; in practice every module in the
  list is already imported by other tests/fixtures before this test
  runs, so we were never actually getting a fresh import anyway — just
  destruction.

  CI workflow tightening (separate concern, same PR since both touch
  the test infrastructure):

  - Dropped -v from the pytest invocation. 5300+ "PASSED foo::bar"
    lines per worker were eating ~30-60s of stdout I/O on 2-vCPU
    runners. --tb=short is sufficient for failure context.
  - Sharded backend-tests into a 4-way matrix via pytest-split (new
    dev dep). Each shard runs ~1326 tests in ~95s on a 2-vCPU runner;
    all 4 run in parallel so wall-clock drops from 362s -> ~100s.
  - fail-fast: false on the matrix so a single failing shard doesn't
    hide failures in the other three — PRs see the complete failure
    picture in one push.

maziggy b92bdb7d09 fix(test): snapshot _timelapse_baselines inside the patch context to dodge CI race
test_running_observed_captures_baseline_on_restart_recovery was reading
  _timelapse_baselines.get(1) after the patch() with-block exited.
  Locally and under low parallelism this works fine — the dict still
  holds what _capture_timelapse_baseline_at_start wrote. CI under
  xdist's default load-balancing scheduling intermittently saw the
  dict empty by the time the top-level assert ran, even though the
  production code logged "Baseline at print start: 3 video files for
  printer 1" right before returning. The duplicate log line at the
  same microsecond in the captured stderr is the tell — module state
  is being re-touched between the handler completing and the test
  asserting, almost certainly via the session-scoped event_loop
  fixture in conftest.py interacting badly with the per-file
  autouse _clear_baselines teardown of a sibling test on the same
  worker.

  The test is verifying the handler captured the baseline at the
  moment it returned, so capture the relevant value at exactly
  that point — inside the with-block, immediately after the await.
  That's immune to whatever happens to the module-level dict
  afterward.

MartinNYHC f385936c58 Merge pull request #1514 from maziggy/0.2.4.3
**Bambuddy v0.2.4.3**

**⚠ Upgrade Notes — Read Before Updating**

Almost everyone is upgrading from 0.2.4.2. 0.2.4.3 is a patch release on the same 0.2.4 code base — no schema breaks, no Docker entrypoint changes, no Vite/proxy quirks. The in-app Apply Update button in Settings → System → Updates works for Docker and for any native install already on 0.2.4.1 or later.

Make a backup before upgrading via Settings → Backup → Create Backup. Native install with update.sh snapshots the database automatically and rolls back on failure. Docker and fully-manual paths don't.

### Docker

docker compose pull
docker compose up -d

docker-compose.yml doesn't need refreshing — none of the entrypoint, volume, or env-var conventions changed since 0.2.4.

### Native install — recommended path

sudo BRANCH=main /opt/bambuddy/install/update.sh

Snapshots the database first and rolls back on failure.

### Native install — manual path

sudo systemctl stop bambuddy
cd /opt/bambuddy
sudo -u bambuddy git fetch --prune --tags --force origin
sudo -u bambuddy git checkout main
sudo -u bambuddy git reset --hard origin/main
sudo /opt/bambuddy/venv/bin/pip install -r requirements.txt
sudo systemctl start bambuddy

**Behaviour changes to know about**

- "Prefer Lowest Remaining Filament" now reads from your inventory, not the printer's RFID counter. Slots bound to a Bambuddy or Spoolman spool sort by your remaining-grams figure first; MQTT-only slots fall back to the previous logic. If you use the preference and have bound spools, the dispatch will start picking a different slot than before — the one that actually has less filament left in your inventory. (#1508)

- Camera live view: ffmpeg's RTSP socket-timeout flag is now probed at runtime. Native-Ubuntu installs with a transitional-era ffmpeg were hitting Address already in use because that ffmpeg repurposed -timeout into a listen-mode option. No user action — but if you'd manually patched your install to drop the flag, you can revert. (#1504)

- Cloudflare-fronted installs: CSP script-src is now nonce-based. If you'd added 'unsafe-inline' to your reverse-proxy CSP as a workaround for Cloudflare's auto-injected Rocket Loader / email-obfuscation script, remove it — it's no longer needed. (#1460 follow-up)

- The 0.2.4 feature-freeze still holds for 0.2.5-bound work. A handful of feat: items shipped in this release because they were already in flight before the freeze and would have stranded the original reporters until the 0.2.5 cycle (Spanish locale #1243, the slicer-filter series #1325, cross-printer re-slicing). Everything else from now on is fix-only on the 0.2.4 train.

---

**Highlights**

0.2.4.3 closes two long-running issue clusters and lands the self-service triage infrastructure the support queue has been asking for. The #1325 slicer-filter series is finally complete — Process / Filament dropdowns in the Slice dialog now filter by your selected printer and nozzle diameter, with the right answer whether you've uploaded a Slicer Bundle or are relying on the @BBL preset-name fallback. The #1395 camera reliability series picks up P2S stream stability, ffmpeg stderr capture on   stalls, and the cross-ffmpeg-version RTSP timeout flag that was breaking live view on native Ubuntu (#1504). Around them: a new Connection Diagnostic for "printer won't connect" triage, a Log Health Scanner that surfaces self-fixable issues before they hit the support queue, and a Virtual Printer Setup Diagnostic with one-click slicer-cert export — all three are now auto-attached (sanitized) to support bundles and bug reports.

Plus the largest fix tally of any 0.2.4.x patch — re-slicing correctness across nozzle classes and multi-plate sources (#1493 + the slice-all toggle), "Prefer Lowest Filament" now reads from your inventory instead of the printer's RFID counter (#1508), timelapse re-attaches after a backend restart mid-print (#1485 follow-up), and a full Spanish locale (#1243). Security: idna >= 3.15 for CVE-2026-45409 (ReDoS) and starlette >= 1.0.1 for PYSEC-2026-161 (malformed Host header).

  ---

**New Features**

- Connection Diagnostic — self-service triage for "printer won't connect / won't print" — Triage review of recently-closed issues found roughly a third were user-side setup errors (wrong IP after DHCP renew, LAN-mode toggle off, access code mismatch, port-block by a router-level guest network). The new per-printer diagnostic runs the full layer-1-through-MQTT check in one click — TCP reachability, MQTT TLS handshake, status-message receipt, IP sanity, SSDP visibility — and renders a ranked layer-8 root-cause list with a "Copy to clipboard for bug report" affordance.

- Log Health Scanner + Add/Edit-Printer setup pre-flight — Passive scanner that walks your last N hours of logs against a curated catalog of known-issue signatures (#1480 FTP loop, #1395 ffmpeg drops, #1462 drying-power-off, …) and surfaces matches on the System page. Add/Edit-Printer also runs a pre-save pre-flight that warns before you commit a misconfiguration (e.g. trailing whitespace in the access code, swapped IP/serial).

- Virtual Printer Setup Diagnostic + one-click slicer-certificate export — VP card now exposes a per-VP "Diagnose" button that walks the slicer-side misconfig list (cert not installed in BambuStudio's trust root, FTPS port collision with another service on the bind IP, MQTT-mode mismatch with the target printer). The matching "Export slicer certificate" button writes the right .crt for whichever VP you're testing, eliminating the manual openssl invocation that ate half the VP-related support    tickets.

- Slicer: process & filament profiles now filter by the selected printer (#1325, requested by @IndividualGhost1905) — Picking an X1C in the server-side Slice dialog no longer floods the Process / Filament dropdowns with H2D-only presets. When you've uploaded a Slicer Bundle for that printer, filtering is exact-match against the bundle's contents; without a bundle, falls back to a name-based @BBL heuristic on model + nozzle.

- Slicer: cross-printer re-slicing across nozzle classes + multi-plate slice-all toggle — Re-slicing an X1C archive for an H2D, or re-slicing a parted-statue multi-plate 3MF in one click. The slice-all toggle produces a single output 3MF whose Metadata/plate_N.gcode entries cover every plate, with the filament dropdowns showing the union of slot usage across plates so paint slots from plate 2 aren't invisible.

- Spanish (es) locale (#1243, requested by @MiguelAngelLV) — Full European Spanish translation across all 4899 keys. Joins the existing en / de / fr / it / ja / pt-BR / zh-CN / zh-TW locales; parity check enforces no English-leak.

- Currency: Belize Dollars (BZD) (#1454, requested by @PLGuerraDesigns) — Added to the Settings → Cost currency dropdown.

- Event-loop stall watchdog — makes a frozen backend self-diagnose (#1486 groundwork) — Several "container hangs after adding a printer" reports share a signature that leaves no actionable evidence in the logs. The watchdog logs a full traceback when the asyncio event loop is blocked for longer than the threshold, so the next time it hangs we get a real stacktrace instead of "it just stopped responding".

---

**Changes**

- Support bundle + bug-report submission now include the live diagnostic snapshot. Connection Diagnostic / Virtual Printer Setup Diagnostic / Log Health Scanner results are now persisted into the downloadable support ZIP and the submitted GitHub issue, with IPs / printer names / serials / access codes sanitized via the existing log-sanitizer plus an IPv4 regex fallback. A 4-step progress checklist replaces the spinner so the longer wait is communicated honestly.

- Settings → SpoolBuddy: CPU load tile on the device card. Pulled from the existing system_stats.load_avg heartbeat — no new round-trip.

- Filament inventory: grouped rows now show group totals (#1368) — Collapsed group row now shows the rolled-up Remaining / Total values for the group instead of the values from a single member spool.

- Bug-report panel: connection diagnostic collapses for multi-printer setups so the panel doesn't overflow when you have eight printers.

- Color Catalog sync now identifies itself as Bambuddy to filamentcolors.xyz. Honest User-Agent — Bambuddy/<version> instead of the bare python-httpx/x.y.z default. Same compliance-audit pass that produced today's Bambu Lab outreach.

---

**Fixed**

Slicer / slicing

- Slicer process / filament dropdowns now filter by nozzle diameter too (#1325 follow-up #2, reported by @IndividualGhost1905) — With the @BBL name fallback in place, an X2D 0.4 selection was still admitting 0.2 / 0.6 / 0.8 nozzle process variants. The regex now parses both model AND nozzle from preset names; differing nozzles fall into the "Other printers" group.

- Slicer process / filament dropdowns now filter for users without uploaded Slicer Bundles (#1325 follow-up, reported by @IndividualGhost1905) — Original #1325 fix relied on the user having uploaded a .bbscfg; reporters running without one saw no filtering at all. The name-based @BBL fallback now produces sensible filtering even when no bundle is present.

- Slicer: process / filament dropdowns now filter by printer using uploaded Slicer Bundles (#1325, reported by @IndividualGhost1905) — Root fix for #1325 — replaces the preset-name guessing heuristic with bundle-backed exact match.

- Re-slicing across the single-nozzle / dual-nozzle boundary now actually works (#1493) — Re-slicing a model sliced for a single-nozzle printer (X1C, P1S, A1, P2S, …) onto a dual-nozzle printer (H2D, X2D) — or vice versa — now produces a correct output 3MF. Per-plate loop handles the bed-bound consolidation that BS CLI's --arrange would otherwise reject.

- Failed slice now opens an error modal instead of a toast that vanishes before it can be read.

- Re-slicing for a different printer no longer silently produces a file for the original printer — Cross-model re-slice was carrying the source's printer_id through, so the resulting archive looked like it belonged to the wrong printer in the UI.

- Re-sliced archive now shows the printer it was sliced for, not the source's printer.

- Sliced files no longer report "0 g" filament usage — Archive card and slice-result both showed filament_used_g: 0 for real multi-hour prints.

- Flow Calibration now actually runs when the print option is enabled (#1478, reported by @andreirusu99) — H2S reporter saw poor extrusion around corners; root cause was the Flow Calibration option being silently skipped because the wrong project_file field was being passed to the printer.

- File Manager: list-view actions no longer clipped; preview modal Slice button now respects the Slicer API setting.

Camera

- X1/H2/P2 live camera no longer fails with Address already in use on transitional ffmpeg builds (#1504, reported by @rage03usa, confirmed by @PawseHaxor) — Native-Ubuntu reporter was retrying indefinitely with Unable to open RTSP for listening … Address already in use because that ffmpeg version repurposed -timeout into a listen-mode option. Runtime probe now picks -stimeout or -timeout based on what ffmpeg advertises, covering the full pre-deprecation / transitional / modern range without regressing either end.

- Camera: P2S RTSP stream no longer drops every frame after the first (#1395, reported by @Tschipel)

- Camera: ffmpeg stderr is now captured when an RTSP stream stalls (#1395, reported by @Tschipel) — Previously stderr was only captured when ffmpeg actually crashed, so silent stalls left no diagnostic trace.

- Camera diagnostic (stethoscope) is now visible in the pop-out camera window (#1395, reported by @Tschipel)

Inventory / scheduler

- "Prefer Lowest Remaining Filament" now uses Bambuddy's inventory weight, not just the printer's RFID counter (#1508, reported by @kleinwareio) — Reporter had a cloned spool in slot 1 (950 g) and the original in slot 4 (50 g), the preference enabled, and the dispatch consistently picked slot 1. Root cause: scheduler was reading the printer's tray.remain (which is -1 for non-RFID spools and ties every slot at the sentinel). Now bound-spool slots sort by Bambuddy / Spoolman remaining-grams first; MQTT-only slots fall through to the previous logic.

- Scheduler: queue items with force_color_match filament overrides now produce a correct AMS mapping at dispatch (#1437, fixed by external PR #1440 from @Person2099) — When a queue item had force_color_match overrides but no specific plate (plate_id=None), the scheduler was dispatching with ams_mapping: null and the printer was picking AMS slots by filament type only, ignoring the required colour entirely. Contributor fix walks <plate> elements first in filament_requirements.py and falls back to legacy _collect_filaments only when the modern format is absent.

- Archive filament colour now reflects the assigned inventory spool, not the slicer's 3MF (#1494, reported by @IndividualGhost1905) — Adding a #000000 black filament was being overridden by the 3MF's embedded colour.

- Insufficient-filament pre-print warning now fires on every dispatch path (#1496, reported by @needo37) — Pre-print check was only firing for one of the three dispatch entry points.

Spoolman

- OpenSpoolman-tagged spools are now selectable in the AMS-slot assignment picker (#1122, reported by @mithkr) — Reporter runs Bambuddy alongside OpenSpoolman; OpenSpoolman writes a different tag shape into spool.extra, which the assignability check was rejecting. Now decided from the slot-assignment ledger instead of the tag field.

- Missing-spool-assignment notification no longer false-fires on every Spoolman-mode print (#1473, reported and root-caused by @ojimpo) — Check was only querying one of the two assignment tables.

- Per-print weight reporting now works for tag-less spools assigned via the Bambuddy UI (#1459, reported by @Moskito99 — follow-up to #1119) — Postgres + Spoolman reporter saw weight updates skip every non-tag spool assigned through the UI rather than via NFC scan.

- AMS hover card and SpoolBuddy fill-bar no longer surface a stale spool after re-assigning a non-RFID slot (#1457, reported by @Menthe11) — P1S reporter with generic non-RFID spools saw the old assignment hang around in both UI surfaces after switching the slot to a different spool.

Archives / timelapse

- Timelapse now attaches to the archive after a backend restart mid-print (#1485 follow-up, reported by @pwostran) — Companion fix to the duplicate-archive guard from #1485. The same first-push guard that prevents the duplicate also prevented the timelapse-baseline capture, so the post-reboot scan couldn't find new files. Baseline is now captured on the first observed RUNNING state when the start callback is suppressed.

- A backend restart mid-print no longer duplicates the job in the archive (#1485, reported by @pwostran)

- Timelapse auto-attach works for VP-queue / dispatch prints (#1403 follow-up, reported by @pwostran) — The snapshot-diff strategy that picks the right MP4 was incorrectly attributing files to the wrong archive for dispatched prints.

File Manager / Library

- "All Files" view now shows files inside subfolders (#1499) — Was previously returning only top-level files.

- Library files now display the filename, not the embedded 3MF Title (#1489, reported by @needo37) — File Manager cards / search / sort were keying off file_metadata.print_name, which mismatched what users actually search by.

- 3D preview no longer freezes the page on complex multi-part 3MFs (#1412, reported by @anthonyma94) — Opening the 3D preview on a multi-colour parted MakerWorld statue hung the browser tab.

- STL thumbnail generation failures now log a full traceback — Surfaced by the #1480 support bundle.

Printers / connectivity

- File Manager no longer polls the printer over FTPS every 30 seconds while open (#1480, reported by @OscarsWorldTech) — P1S reporter's printer was churning through MQTT disconnect/reconnect cycles every 30s because the File Manager was opening idle FTPS sessions to the printer for no functional reason.

- Printer serial numbers normalized on input; stale connection that never receives a status report now logs an actionable hint (#1465, reported by @jmneely94)

- Smart-plug "Auto Off after Drying" no longer kills the printer seconds into a drying cycle (#1462, reported by @Kyobinoyo) — X2D reporter set a 1-hour dry cycle and the smart plug cut power 8 seconds in. False "drying complete" detection on power-up state.

- AMS drying popover now scrolls instead of clipping the Start button on short viewports (#1458, reported by @kleinweby)

- Add Printer no longer hangs the container on P1S (#1445, reported by @psybernoid, confirmed by @thomassjogren) — Regression introduced in 0.2.4.2 by the fix(printers) cleanup.

- FTP: P2S upload truncates / 426 "Failure reading network stream" on Python 3.13 (#1401, reported and root-caused by @iitazz) — P2S firmware 01.02.00.00 reporter on Python 3.13 saw uploads truncate at exactly 1.8 MB.

SpoolBuddy

- Spool ID surfaced everywhere a spool's identity is rendered + Write-Tag page honours Spoolman mode (#1439, reported + partially prototyped by @flom89)

Stats

- Print Activity heatmap buckets prints by local date, not UTC date (#1446, reported and root-caused by @needo37) — CDT (UTC-5) reporter noticed prints finished in the evening appeared on the wrong calendar day.

- Failure Analysis widget no longer shows "Unknown" for archives classified after the fact (#1444, reported and root-caused by @needo37)

UI / PWA

- PWA: in-app install button + self-host the Inter font (#1460, reported by @Soopahfly) — Reporter could install Bambuddy as a PWA on desktop but not on Android, and the font was being fetched from rsms.me on every page load.

- Self-hosted Inter font now actually loads — /fonts/*.woff2 was not served (#1460 follow-up) — The browser console logged downloadable font: rejected by sanitizer because the static mount didn't include the fonts subdirectory.

- Cloudflare-fronted Bambuddy no longer needs an unsafe-inline override to load (#1460 follow-up, reported by @Soopahfly) — CSP script-src switched to nonce-based so Cloudflare's auto-injected email-obfuscation / Rocket Loader script passes without the override.

- Local Profiles: search bar no longer disappears when a query matches nothing (#1470, reported by @pwostran)

- Failure Detection: Status panel Low / High thresholds now reflect the selected sensitivity (#1469, reported by @JohnMacOB)

Security

- idna >= 3.15 — clears CVE-2026-45409 (ReDoS in idna.encode() with crafted Unicode payloads).

- starlette >= 1.0.1 — clears PYSEC-2026-161 (malformed Host header crash in request.url construction).

- PyJWT CVE-2025-45768 permanently ignored in pip-audit — Advisory is disputed by the PyJWT maintainers; Bambuddy auto-generates 86-char secrets via secrets.token_urlsafe(64), file-loaded path rejects secrets shorter than 32 chars.

maziggy eb98521e93 fix(test): use /nonexistent/ instead of /tmp/ to satisfy Bandit B108
The test_returns_empty_when_3mf_missing test sets a deliberately
  non-existent file_path on a PrintArchive to verify
  compute_deficit_for_queue_item handles the missing-3MF branch
  gracefully. The path just needs to fail an existence check — the
  /tmp/ prefix was incidental.

  Bandit B108 ("insecure temp file usage") regex-matches /tmp/,
  /var/tmp/, and /dev/shm/. Dropping /tmp/ in favour of /nonexistent/
  keeps the test behaviour identical (still a guaranteed-missing
  path, still triggers the missing-file branch) while clearing the
  GitHub Advanced Security finding on PR #1514 without adding a
  # nosec annotation.

maziggy 7fbde1ea3d test(docker): include gcode_viewer/ in the test image so the packaging assertion actually runs
Dockerfile.test only COPYed backend/ and pyproject.toml, so the
  integration test at tests/integration/test_gcode_viewer.py:63
  silently pytest.skip'd in every Docker run with "gcode_viewer/
  index.html not present at /app/gcode_viewer/index.html".

  That was deliberate fallback behaviour for unit-test environments
  where the assets are intentionally absent, but in CI it meant the
  #1218 packaging regression (3D Preview returning {"detail":"Not
  Found"} because the embedded PrettyGCode viewer wasn't bundled into
  the prod image) had no test guarding against a recurrence — the
  test that was supposed to catch it was the one being skipped.

  Add COPY gcode_viewer/ ./gcode_viewer/ to the backend-test stage,
  matching the path the production Dockerfile uses (static_dir.parent
  / "gcode_viewer" = /app/gcode_viewer/) so the assertion runs against
  the same layout the app sees at runtime. Path-anchored comment in
  the Dockerfile so a future maintainer doesn't strip the COPY as
  unused.
