maziggy cc25cbe774 fix(archives): #1608 suppress card time-accuracy badge for multi-run archives
compute_time_accuracy in routes/archives.py compares the archive row's
  own started_at / completed_at (which reflect the latest run only)
  against archive.print_time_seconds (which the #1593 parser fix
  correctly stores as the sum across plates). For a 3-plate file printed
  plate-by-plate the ratio is ~300%, producing a "+188%" card badge that
  means nothing — apples to oranges. The 5-500% sanity band catches
  truly broken values but lets this deterministic N×100% shape through.
  Reporter's archive #65 was 3 plates over 9 runs.

  compute_time_accuracy gains an optional run_aggregate argument and
  returns both actual_time_seconds and time_accuracy as null when the
  aggregate reports more than one logged run. The frontend already falls
  through to print_time_seconds for the time display
  (actual_time_seconds || print_time_seconds) and gates the badge on
  time_accuracy being truthy, so multi-run archives now show the slicer
  estimate with no badge. Single-run archives keep the original
  behaviour verbatim.

  The fix is applied at every call site that renders an archive card:
  archive_to_response now threads run_aggregate through, and the three
  endpoints that previously didn't load the aggregate (archives.py
  search fast-path and FTS path, single-archive PATCH, and
  projects.list_project_archives) now batch-load it via the existing
  _load_run_aggregates helper.

  The stats endpoint's per-run accuracy aggregation at archives.py:940
  already uses PrintLogEntry.duration_seconds with its own 50-200% band
  filter and is untouched.

maziggy 9cc4b6aa60 fix(virtual-printer): #1610 add Bambu cipher pin to every slicer-facing TLS context
The #620 patch fixed the OpenSSL-3.x-strips-plain-RSA-AES-GCM cipher
  mismatch on the printer-facing TLSProxy client context. The same fix
  was never applied to the four other slicer-facing TLS contexts. On
  hardened distros (Fedora / RHEL with update-crypto-policies, hardened
  Alpine builds) where the system narrows DEFAULT to forward-secrecy
  only, the slicer's ClientHello finds no overlap with what Bambuddy
  offers and the handshake aborts with the slicer reporting code=-1
  before any application data flows. The reporter pinpointed the missing
  set_ciphers call in bind_server.py against the #620 lineage; the
  audit-wide sweep here extends the same fix to mqtt_server.py,
  tcp_proxy._create_server_ssl_context (the missing other half of #620),
  and ftp_server.py.

  For the three new contexts (bind / mqtt / proxy-server) the cipher
  string is DEFAULT:AES256-GCM-SHA384:AES128-GCM-SHA256 — verbatim match
  with the #620 client-side fix. For FTPS the original HIGH baseline is
  kept (HIGH:AES256-GCM-SHA384:AES128-GCM-SHA256:!aNULL:!MD5:!RC4) so the
  cipher set stays a strict superset of what shipped before — HIGH
  offers ~58 suites DEFAULT doesn't (CCM / ARIA / CAMELLIA / DSS) that
  no Bambu slicer is known to pick, but narrowing a compat surface
  without proof would violate the existing don't-remove-compat-pinning
  rule. TLS version pins (TLSv1_2 minimum across all four, TLSv1_2 max
  on FTPS for the BambuStudio PSK-reuse compat) and verify-mode settings
  are unchanged — only the cipher list is widened.

maziggy fee7c722f5 fix(usage-tracker): #1607 filter empty AMS slots from position-based fallback
When no explicit slot-to-tray mapping is captured (path 5 of 6 in
  _track_from_3mf — fires before the request-topic subscription that catches
  ams_mapping is accepted), the tracker builds available_trays from
  build_ams_tray_lookup and uses position to map the slicer's Nth filament
  to the Nth available tray. The helper enumerated every AMS tray by id
  regardless of whether a spool was loaded, so AMS slots 0-2 loaded + slot 3
  empty + external yielded available_trays = [0, 1, 2, 3, 254]. The slicer
  compacts its filament UI to hide empty AMS slots, so its 4th filament is
  the external — but position mapping routed it to AMS0-T3 (the empty slot)
  instead of 254 (external). No spool assigned there → usage silently
  skipped → external never decremented.

  Filter the fallback to slots with a non-empty tray_type. build_ams_tray_lookup
  stays unchanged for its other callers (spoolman_tracking.store_print_data,
  routes/printers, spool_assignment_notifications); the filter is applied at
  the usage-tracker call site only. Mirrors the existing vt_tray filter in
  build_ams_tray_lookup line 174.

maziggy cdc27eb517 fix(virtual-printer): #1429 follow-up — auto-resolve VP IP when bind_address is 0.0.0.0
The original #1429 fix's _refresh_ip_encoding early-returned when
  mqtt_server.bind_address was "0.0.0.0" or empty (the default for VPs created
  without a dedicated bind IP). On a flat-LAN install that's the typical case,
  so the encoding never armed, _rewrite_net_info_ips was a no-op on every push,
  and the slicer kept following the real printer IP to its SD card. @Mape6
  reported this on the 2026-06-02 daily that supposedly fixed the bug.

  New helper _resolve_host_interface_for_target() consults the existing
  network_utils.find_interface_for_ip() to pick the host interface in the
  printer's subnet. _refresh_ip_encoding falls back to it when bind_address
  is unspecified; an explicit bind IP still wins. INFO log line distinguishes
  the two paths ("armed: ... (bind_address)" vs "(auto-resolved)") so future
  bundles directly answer which IP the rewrite picked.

  Tests: 4 new under TestBindAddressAutoResolve — rewrite arms via auto-resolved
  IP at bind_address=0.0.0.0; stays disabled if no interface matches (no crash);
  explicit bind_ip still takes precedence; helper returns None defensively when
  find_interface_for_ip does.

maziggy 673001e3cd fix(maintenance): #1596 persist wiki_url on Custom Type create + correct
inline mutation type

  POST /api/v1/maintenance/types hard-coded the MaintenanceType
  constructor and silently dropped `wiki_url`, so the Documentation URL
  field disappeared after save. PATCH worked because it uses
  `data.model_dump(exclude_unset=True) + setattr`, which is why editing
  a freshly-created type DID save the URL — masking the bug under any
  "save then immediately fix it" retest. Reporter @BurntOutHylian
  pre-triaged the issue to the exact constructor call at
  routes/maintenance.py:206-213; fix is the missing `wiki_url=data.wiki_url`
  argument.

  Frontend nit from the same report: MaintenancePage.tsx:1131's
  `updateTypeMutation` declared `data: Partial<{ name; default_interval_hours;
  interval_type; icon }>` — omitting `wiki_url`. The value reached the
  API correctly at runtime because `api.updateMaintenanceType` accepts
  `Partial<MaintenanceTypeCreate>` (which has wiki_url), but the inline
  type lied about the payload shape. Extended the inline `Partial<{...}>`
  to include `wiki_url?: string | null`. Pure type fix — no runtime change.

maziggy a837a3acbd ● fix(library): #1600 thumbnail extraction for external-folder .gcode.3mf
files + unify file_type classification across ingest paths

  #1600: external-folder sliced outputs landed
  with no thumbnail. Cause: four backend ingest paths classified
  LibraryFile.file_type differently for the same .gcode.3mf family.
  upload / ZIP-extract / in-process used os.path.splitext()[1] which
  returns .3mf for foo.gcode.3mf and stored file_type="3mf", matching
  the thumbnail-extraction gate at library.py:1467 (file_type == "3mf").
  External-folder scan explicitly detected the compound and stored
  file_type="gcode.3mf" — preserving "sliced output" identity — but
  then skipped both the "3mf" gate and the "gcode" gate, so the file
  landed with thumbnail_path = None. Same compound-extension drift that
  bit #1543 in the 3D preview, in a surface that audit didn't trace
  back to.

  Unified fix:

  - New classify_file_type(filename) helper in routes/library.py is the
    single source of truth. Returns "gcode.3mf" for sliced outputs and
    ext[1:] otherwise.
  - Applied to every ingest path: upload (line 1704), ZIP-extract
    (1998), external-folder scan (the bug site — the manual compound
    check is replaced), and in-process save_3mf_from_bytes (471, used
    by MakerWorld import).
  - External-scan thumbnail gate widened to
    `if file_type in ("3mf", "gcode.3mf"):` — a .gcode.3mf IS a 3MF zip
    with Metadata/plate_1.png; ThreeMFParser doesn't care about the
    trailing extension.
  - gcode-download endpoint at GET /library/files/{id}/gcode had the
    same drift in reverse: gate was `elif file.file_type == "3mf":` so
    a row stored with file_type="gcode.3mf" (the external-scan path's
    pre-unification behaviour, and the canonical going forward) got
    rejected with HTTP 400. Widened to the same compound-aware tuple.

  One-shot DB migration in core/database.py::run_migrations backfills
  existing legacy rows:

    UPDATE library_files
       SET file_type = 'gcode.3mf'
     WHERE file_type = '3mf'
       AND LOWER(filename) LIKE '%.gcode.3mf'

  Idempotent (post-update rows no longer match the file_type='3mf'
  predicate, so re-runs at every boot are no-ops) and dialect-neutral
  (LOWER + LIKE are identical under SQLite and Postgres). Without the
  backfill, users would have a permanent split state: old uploads at
  '3mf', new uploads at 'gcode.3mf' — which would double-bucket sliced
  outputs in the dashboard stats query at line 4615 and show two
  entries in the file-manager filter dropdown for the same conceptual
  type.

  Frontend untouched. FileManagerPage.tsx and ProjectDetailPage.tsx
  already accept both '3mf' and 'gcode.3mf' per the #1543 fix. After
  the migration the DB only contains canonical values, so the legacy
  '3mf' branches in the frontend become dead code for sliced files —
  they stay as defence-in-depth in case any future ingest path I
  missed reverts to the legacy classifier.

maziggy 5d6d928b3f fix(virtual-printer): #1429 net.info[*].ip cache leak + mode wire-value rename
#1429 (reported by @TrickShotMLG02, confirmed by @Mape6 on a flat single-LAN
  that rules out subnet / mDNS-reflector theories): with the physical printer
  off the slicer's "Send" landed in Bambuddy's archive; once the printer
  powered on every subsequent "Send" went straight to the printer's SD card
  and bypassed Bambuddy. Bundle analysis: mape6-before showed clean FTP
  receive + archive lines, mape6-after had zero FTP attempts to Bambuddy
  once the printer was online.

  Cause: mqtt_bridge.py::_resolve_client encoded _target_ip_uint32_le /
  _vp_ip_uint32_le ONLY on client-identity change and early-returned on
  every refresh tick when the same client object was still bound. If
  target_client.ip_address was empty at first bind (DB row stale, or client
  constructed before SSDP refresh filled it in), the encoding stayed None,
  the net.info[*].ip rewrite block was skipped, the cache filled with the
  real printer IP, sticky-key preservation kept the poisoned net value
  alive across every subsequent incremental push, and the slicer followed
  the leaked IP. Only Bambuddy-restart-with-printer-off cleared it — the
  workaround both reporters independently arrived at. Same shape on
  multi-NIC printers (X1C, H2D Pro): the rewrite only matched entries
  whose ip equalled _target_ip_uint32_le, so a secondary interface IP
  Bambuddy never saw would leak through unchanged.

  Bridge fix:
  - _resolve_client calls a new _refresh_ip_encoding() on every refresh
    tick, even when client identity is unchanged; self-heals once
    ip_address becomes valid.
  - _refresh_ip_encoding() sweeps the existing _latest_print_state when
    encoding becomes valid for the first time. Without the sweep,
    sticky-key preservation keeps the pre-arm poisoned cache alive
    forever — incremental pushes that don't include net carry the bad
    value forward.
  - _rewrite_net_info_ips() rewrites EVERY non-zero net.info[].ip entry
    that doesn't already equal the VP IP, not just entries matching
    _target_ip_uint32_le. Multi-NIC printers stop leaking secondary
    interfaces. Zero-IP placeholders are left alone so "active interface"
    detection still works.
  - INFO logging on encoding arm/update and on cache sweep so future
    bundles directly answer "did the rewrite fire?".

  Mode wire-value rename (#1429 follow-up, separate confusion source):
  - Both reporters' support bundles showed mode: immediate while the UI
    said "Archive"; @TrickShotMLG02 quoted: "I have no idea why it says
    immediate in the support-info.json file. In the webui the printer is
    set to archive". UI button "Archive" had always saved immediate, and
    "Queue" had always saved print_queue. Canonical wire values are now
    archive / review / queue / proxy, matching the button labels 1:1.
  - New normalize_vp_mode() + VP_MODE_* constants in
    models/virtual_printer.py; manager.py normalises on construction so
    a legacy row read pre-migration still dispatches correctly.
  - core/database.py::run_migrations rewrites existing virtual_printers
    and settings rows; idempotent (re-runs are no-ops); identical SQL
    under SQLite and Postgres.
  - API routes accept both legacy and canonical on input, normalise
    before storage. GET /settings/virtual-printer normalises on read so
    the frontend's mode-button highlight works for stale legacy values.
  - Three frontend VP components (VirtualPrinterSettings,
    VirtualPrinterCard, VirtualPrinterAddDialog) switched click handlers
    and type aliases to canonical; each got its own normalizeMode()
    helper so a stale-cached settings payload still highlights the right
    button. Two pre-existing `printer.mode === 'queue' ? 'review'`
    legacy mappings in VirtualPrinterCard were the source of a test
    failure caught mid-implementation where the new canonical 'queue'
    was being mis-aliased back to 'review' and hiding the auto-dispatch
    + force-color-match toggles.

  mode handler is NOT the dispatch bug: manager.py::_archive_file (the
  handler for archive mode) doesn't dispatch to the physical printer.
  The "files end up on the printer's SD card" symptom was the IP-leak
  from the bridge cache. The mode rename is purely clarity / support-
  bundle accuracy.

maziggy 1e08c25a9f fix(stats): #1593 multi-plate parser + per-run project rollup + carry-over system totals + accuracy band
Two stacked causes under-reported multi-plate prints in the project
  rollup and the archive card.

  Root cause 1 - parser only read plate 1.

  ThreeMFParser._parse_slice_info used root.find(".//plate") and pulled
  prediction / weight from that one element. Any multi-plate file's
  archive-level print_time_seconds / filament_used_grams reflected
  plate 1 alone. The /plates endpoint already looped findall and was
  correct, which is why the plate carousel showed the right numbers
  while the archive card was wrong.

  Fix: loop every <plate> and sum prediction + weight. Per-plate
  concepts (plate_number, _plate_index, printable_objects) only set
  when there's exactly one plate - for multi-plate exports the
  archive represents all plates and a single index doesn't apply at
  the file level. bed_type keeps the first plate's value as a
  best-effort default. Malformed prediction / weight on individual
  plates skip cleanly rather than poison the sum.

  Root cause 2 - project rollup aggregated PrintArchive, not the
  per-run log.

  compute_project_stats and list_projects quick-stats summed
  PrintArchive.print_time_seconds / filament_used_grams / cost /
  energy_* WHERE project_id. A reprint reuses the source archive row
  and writes a new PrintLogEntry, so 3 sequential runs collapsed to 1
  archive - and that archive's numbers were already plate-1-only from
  cause 1. The Archive Print Log path was already correct because it
  drove off print_log_entries (archives.py:420 comment).

  Fix: both compute_project_stats and the list_projects quick-stats
  block inner-join print_log_entries -> print_archives WHERE
  archives.project_id. total_archives becomes COUNT(PrintLogEntry.id),
  failed_prints counts runs in failed/aborted/cancelled/stopped,
  completed_items is SUM(PrintArchive.quantity) for runs where
  status='completed', time/filament/cost/energy from PrintLogEntry.
  Orphan log rows (archive_id IS NULL post archive deletion) are
  excluded by the inner join.

  Same-shape fixes carried forward (no follow-ups per project rule):

  system.py system-info totals: total_print_time / total_filament
  had the same bug shape - summed PrintArchive directly so reprints
  collapsed to one row. Now sums PrintLogEntry.duration_seconds /
  filament_used_grams. The semantic shift is also a correctness
  improvement: the field now reflects time the printer actually spent
  printing, not slicer-estimated time.

  archives.py time-accuracy metric: estimate / actual per run where
  estimate = PrintArchive.print_time_seconds. Post-parser-fix
  multi-plate archives have file-level estimate but per-run actual =
  one plate, so ratio = N x 100% for an N-plate file. The calc now
  clamps each row to the [50%, 200%] plausibility band before
  contributing to the printer-level average; single-plate accuracy
  (the case the metric is designed for) stays fully included.

  Backfill: users with AMS spool tracking - the reporter's case - have
  per-run filament_used_grams from the tracked spool delta, so stats
  become correct immediately. Users without tracking fall back to the
  archive estimate and undercount until they reprint. Archive card
  still reads PrintArchive.filament_used_grams directly so old
  multi-plate archives keep plate-1-only numbers until reslice -
  forward-only as the reporter accepted.

maziggy c9bc5eb4e9 fix(webhook): #1584 PrinterState dataclass attribute access in status / stop / cancel
webhook.py treated printer_manager.get_status() return as a dict and
  called .get(...) on it. The return is a PrinterState dataclass
  (backend/app/services/bambu_mqtt.py), so the call raised AttributeError
  and Starlette surfaced it as a generic 500 for every printer with a
  status row. Non-existent printers correctly returned 404 because the
  early "Printer not found" branch fired before the crash.

  Reporter's repro matched exactly: id 1 (existing printer) returned 500,
  id 2 and id 3 (no row) returned 404. Verified end-to-end against a live
  PG-backed instance with the reporter's key shape — same 500 before the
  patch, 200 with the correct payload after.

  8 crash sites across 3 routes:
    - webhook_get_printer_status   GET  /printer/{id}/status      5 sites
    - webhook_stop_print           POST /printer/{id}/stop        2 sites
    - webhook_cancel_print         POST /printer/{id}/cancel      2 sites

  Every status.get("X", default) replaced with status.X if status else
  default. Pydantic response schema unchanged; PrinterState's dataclass
  defaults cleanly cover the "registered but never connected" branch so
  the status route now returns 200 with connected=false, state=null
  rather than crashing.

maziggy 171848a0fc fix(slicer-presets): #1581 SliceModal refresh + invalidate on local-profile delete/import
Two-part fix for the reporter's "removed profiles still show on the slice
  menu" symptom.

  Local half (real bug). LocalProfilesView's import and delete mutations
  invalidated ['localPresets'] (the management view's own query) but not
  ['slicerPresets'] (the SliceModal's unified preset query, staleTime 60s).
  A freshly-deleted preset kept rendering in the slice dropdown until that
  staleTime elapsed plus a refocus/remount. Both mutations now also call
  queryClient.invalidateQueries({queryKey: ['slicerPresets']}).

  Cloud half (opt-in cache bypass). _fetch_cloud_presets keeps a 5-minute
  per-(user, token) in-process cache (slicer_presets.py:69, balances
  "users see freshly-saved presets quickly" against "busy install doesn't
  hit Bambu Cloud once per modal open"). Users delete cloud presets in
  Bambu Studio / Bambu Handy, not in Bambuddy, so there's no event hook
  to invalidate on. Rather than shorten the TTL globally, the listing
  endpoint gains an opt-in ?refresh=true query param that bypasses both
  the cloud cache AND the 1-hour bundled-preset cache for that one call;
  the fresh result is still written back so subsequent normal callers
  keep hitting the cache.

  New SliceModal "Refresh" button. Lives in the preset section header
  next to the cloud-status banner. Calls getSlicerPresets({refresh: true})
  and writes the fresh slots into the ['slicerPresets'] cache via
  queryClient.setQueryData so the spinner stops immediately rather than
  triggering a second refetch. RefreshCw icon spins while in-flight;
  disabled during slice enqueue to prevent double-fire.

maziggy 396e9aa09e security: harden path-traversal class across routes + services; fifth CI backstop
Two attacker-controlled strings were being joined to library_dir with no
  resolve + containment check in the project ZIP import endpoint:

    - linked_folders[*].name from the request's project.json
    - per-entry zf.namelist() paths from the ZIP itself

  An absolute path in either field collapsed the join (Path("/lib") / "/etc"
  becomes Path("/etc") because pathlib discards the left side when the right
  is absolute) and the next write_bytes landed wherever the attacker chose.

  Adjacent finding from the routes audit: GET /archives/{id}/photos/{filename}
  had NO validation on filename and FileResponse-served arbitrary paths -
  the DELETE counterpart at least gated on the photos membership check.

  Adjacent finding from the services audit: ArchiveService.attach_timelapse
  wrote archive_dir / filename where filename ultimately came from a printer's
  FTP listing (compromised-printer threat model) or the /timelapse/select
  query param. A malicious printer that exposes a directory entry with ..
  segments could write the timelapse outside the archive directory.

  New backend/app/utils/safe_path.py::safe_join_under(parent, *parts) is the
  single source of truth: rejects empty / null-byte / absolute parts up-front,
  joins under parent, resolves both sides, asserts is_relative_to. Returns the
  resolved canonical path on success, raises HTTPException(400) on escape, or
  PathTraversalError when http=False (for service-layer callers that need to
  match a non-HTTP return contract).

  Wired into the import vectors, both archive photo handlers, and the
  attach_timelapse service. The full audit sweep inspected every Path/Name
  join in backend/app/api/routes/ AND backend/app/services/ - 25 route-layer
  sites + 8 service-layer sites confirmed safe and tagged with
  # SEC-PATH-OK: <reason> so future audits trust the inline guard at a glance.

  Fifth CI backstop test_route_path_arithmetic_is_safe_joined_or_marked
  AST-walks both layers and fails the build on any <dir-like>/<bare variable>
  join that doesn't either route through safe_join_under or carry the marker.
  The services layer is in scope because it receives values verbatim from the
  routes AND from external sources Bambuddy has no control over (the printer
  FTP-listing case above).

  SECURITY.md gets a fifth rule + a fifth row in the CI test mapping table;
  the rule now names the printer FTP-listing case explicitly so future
  services-layer audits set the right expectation.

  fix(library): suppress warning storm when bulk-uploading ZIPs of empty/stub STL files

  Uploading a ZIP of stub or empty STL files (e.g. the 24-byte
  "solid test\nendsolid test" shape) produced one WARNING per file in
  stl_thumbnail.py::generate_stl_thumbnail. The warnings were technically
  correct - trimesh returns a valid Mesh with zero vertices, the safeguard
  matches, and the function returns None so the library entry is still
  created without a thumbnail - but the volume turned a successful upload
  into thousands of WARNING lines in the journal.

  Two changes:

  1. The per-file "Failed to load STL or empty mesh" message in
     stl_thumbnail.py is now logger.debug instead of logger.warning. It's
     a per-file content observation, not an actionable error; the caller
     already handles None correctly. The branch now catches the rare
     "large enough but trimesh still can't parse it" case, visible in
     debug logs without spamming production.

  2. New module constant MIN_USABLE_STL_BYTES = 200 (smallest binary STL
     with one triangle is 134B, smallest ASCII ~150B; 200 is a safe floor
     below any real STL). The three thumbnail call sites in library.py
     (extract_zip_file, single-file upload, _backfill_external_stl_thumbnails)
     pre-skip files below this size before calling generate_stl_thumbnail.
     Stubs never enter the trimesh pipeline at all.

  Behavior is unchanged for real STLs: any file >=200 bytes runs through
  the existing pipeline, MAX_VERTICES still triggers simplification at
  100k vertices for the 256x256 thumbnail render, large files still get
  thumbnails.

------------

  fix(stl-thumbnail): silence matplotlib first-import noise (writable cache + font_manager log level)

  On first STL upload, three matplotlib-internal log lines surfaced:

    WARNING [matplotlib] /opt/claude/.config/matplotlib is not a writable directory
    INFO    [matplotlib.font_manager] Failed to extract font properties from NotoColorEmoji.ttf
    INFO    [matplotlib.font_manager] generated new fontManager

  The writable-dir warning fired because Bambuddy's $HOME isn't writable for
  matplotlib's default config path; matplotlib fell back to /tmp/matplotlib-XXX
  which lost the font cache on every host reboot, so font_manager rebuilt it
  each cold start - producing another batch of INFO lines.

  Fix is two small additions in stl_thumbnail.py before the matplotlib import:

  1. New _configure_matplotlib_cache() sets MPLCONFIGDIR to
     settings.base_dir/.cache/matplotlib (mkdir if missing) so the cache
     persists across container restarts and the writable-dir warning never
     fires. Respects an externally-set MPLCONFIGDIR so operators who chose
     their own path aren't overridden. Best-effort with a debug fallback if
     settings can't be imported or the mkdir fails.

  2. logging.getLogger("matplotlib.font_manager").setLevel(WARNING) at module
     import demotes the per-font INFO scan that fires when font_manager
     builds its cache cold. Real font warnings (>= WARNING) still surface.

  3 new tests: font_manager logger at WARNING after module import;
  _configure_matplotlib_cache creates the directory under base_dir and sets
  MPLCONFIGDIR; an externally-set MPLCONFIGDIR is preserved verbatim.
  5516 backend tests green, frontend gates clean.

maziggy db9b20631c fix(cloud): #1575 surface actionable error when Bambu Cloud Cloudflare challenge swallows the JSON response
When Cloudflare in front of bambulab.com returns a "Just a moment..." interstitial
  instead of the JSON the API normally produces, the parse error in
  verify_totp / verify_code / login_request used to surface as the opaque "Invalid
  response from Bambu Cloud" or a generic 401 from BambuCloudAuthError. Reporter
  hit this with three back-to-back TOTP attempts; a curl from a different network
  with the same honest Bambuddy UA returns clean JSON, so the trigger is CF-side
  (per-IP / TLS-fingerprint / rate / transient mitigation), not our code.

  Add a small _detect_cloudflare_challenge() helper that inspects the response for
  four CF markers (body "Just a moment...", body "challenges.cloudflare.com", 403
  with cf-mitigated header, 503 with cf-ray header) and returns a message that
  attributes the block to Bambu Lab's Cloudflare protection, suggests waiting a few
  minutes, and points the user at a same-network browser sign-in as the standard
  workaround. Wired into all three JSON-parse sites; verify_totp previously had a
  defensive catch, login_request and verify_code now do too.

  No header changes, no impersonation, no retry loop - pure diagnostics. Stays
  clearly on the right side of Bambu Lab's "no falsified client identity" line.

maziggy be15a375a6 fix(oidc): #1569 populate User.email from standard 'email' claim when email_claim is preferred_username
When an operator configures `Email Claim = preferred_username` (e.g. Authentik) the
  primary `_resolve_provider_email` correctly rejects the identity value as non-email
  shaped and returns None, leaving auto-provisioned users with `email=None` even though
  the same token carries a valid standard `email` claim.

  Add a narrow fallback in the auto-create-users branch only: when
  `provider.email_claim != "email"` and the primary returned None, resolve the standard
  `email` claim with the same Fall A/B shape + email_verified enforcement and use it for
  `User.email` and `UserOIDCLink.provider_email`.

  The auto-link-existing-accounts gate is left on the primary `provider_email`, so the
  GHSA Fall-B / Fall-C guards remain intact - the fallback never feeds account matching.

maziggy ec51394196 fix(security): GHSA-r2qv-8222-hqg3 — allowlist API-key permissions (CVSS 9.9)
API-key permission gates went from a 17-entry admin denylist with the three
  documented scope flags (can_read_status / can_queue / can_control_printer)
  enforced only inside /api/v1/webhook/* to an explicit per-Permission
  allowlist consulted by every dependency:

    - core/auth.py: _APIKEY_SCOPE_BY_PERMISSION maps every non-admin
      Permission to one scope flag on APIKey; unmapped = 403.
      _check_apikey_permissions now takes the api_key and checks the flag.
    - require_any_permission_if_auth_enabled + require_ownership_permission
      were returning None for any valid key with zero scope check; both now
      invoke _check_apikey_permissions and fail closed.
    - Two new scope flags on api_keys: can_manage_library (LIBRARY_UPLOAD /
      UPDATE_OWN / DELETE_OWN / MAKERWORLD_IMPORT) and can_manage_inventory
      (INVENTORY_CREATE / UPDATE / DELETE / FORECAST_WRITE — required by
      SpoolBuddy kiosks). Default TRUE, backfilled from can_queue so existing
      "queue-only" keys keep working and hardened "read-only" keys do not
      silently gain writes.
    - CLOUD_AUTH now routed through can_access_cloud for defence-in-depth
      alongside the existing _cloud_api_key_gate.
    - Migration column-existence check (_api_keys_column_exists) gates the
      backfill so user-edited values are never overwritten on restart.

  Structural drift backstop: test_every_permission_has_a_classification fails
  CI on any new Permission added without an explicit scope mapping —
  prevents the denylist-shape regression that grew the prior surface.

  Backend 5469 tests green; ruff clean. Frontend build green; i18n parity
  green across 9 locales (5005 leaves each, +6 new keys). Wiki permissions
  table + allowlist callout + upgrade notes updated.

maziggy 4ffefa60f4 chore(vp): per-minute MQTT status-push counter for idle-disconnect triage (#1548 follow-up)
The 1 Hz status push was silent at INFO, so support bundles couldn't show
  whether the push task was actually reaching a specific slicer connection.
  Now ``_periodic_status_push`` emits one line per minute per connected
  slicer ("1Hz status push: N pushes/min to <client>") and stays silent when
  no slicer is attached. No behaviour change to the push itself — counters
  are local to the task and reset every 60 ticks.

  Motivated by the open follow-up on #1548: keepalive parser shipped (b6636053)
  and the symptom moved 60 s → 90 s, but OrcaSlicer still disconnects on idle.
  This adds the missing observability so the reporter's next support bundle
  shows whether our outbound 1 Hz push is alive for the disconnecting
  connection.

maziggy e10462678f fix(security): GHSA-6mf4-q26m-47pv — fail-closed on auth-probe DB errors (CVSS 9.8)
is_auth_enabled() and auth_middleware both caught every exception during
  the auth-state probe and returned the "allow" answer instead of denying
  the request. Reporter's PoC floods /api/v1/auth/login to exhaust file
  descriptors, forcing the next SQLite connect to raise, then hits a
  protected endpoint during the fail-open window with no token — granting
  unauthenticated access to admin-account creation, API-key creation, DB
  backup download, and printer control. CWE-636 / CWE-755. Affects >= 0.1.6.

  Fix:
  - is_auth_enabled (backend/app/core/auth.py): only returns False for the
    legitimate "settings row absent" case; any actual exception propagates
    so the caller can deny the request.
  - auth_middleware (backend/app/main.py): returns 503 on any probe failure
    instead of await call_next(request).

  4 new regression tests in test_auth_fail_closed.py pin the contract
  (propagates DB exceptions, returns False for no-row, True for "true",
  False for "false"). 1 existing security test renamed and updated to
  accept either 500 or 503 (both fail-closed) and to verify the
  SQLAlchemy detail does not leak in the body.

  Codebase grep confirmed no other auth-decision predicate has the same
  fail-open shape: _validate_api_key returns None on catch (→ 401 fail-
  closed downstream), is_advanced_auth_enabled propagates correctly,
  permissions.py has no catch-alls.

maziggy 597762685c fix(virtual-printer): #1558 Send pre-flight + slicer-surface audit bundle
#1558: cached-as-base push_status only forced gcode_state=IDLE while letting
  the real printer's live-progress fields (mc_percent, stg_cur, layer_num, ...)
  leak through. Bambu Studio's Send pre-flight read them as busy and refused.
  The cached branch now overrides the activity-field set the same way it
  already overrode storage indicators (#1228) and protocol fields.

  Same bundle ships a multi-round VP audit that found adjacent bugs in the
  same family:

  - #1558: cached branch zeroes mc_print_stage / mc_percent / mc_remaining_time / stg / stg_cur / layer_num / total_layer_num / print_error
  - MQTT auth: per-IP rate-limit (5/60s lockout), hmac.compare_digest, access_code redacted in DEBUG log
  - FTP cmd_STOR streams chunks to disk + 4 GiB cap (was buffering whole upload)
  - Sticky-keys allowlist extended with upgrade_state / xcam / hw_switch_state / nozzle_diameter / nozzle_type / online / ams_status
  - _pending_files cleanup in finally for archive / queue / dispatch handlers
  - _add_to_print_queue position uses MAX+1 (was hardcoded 1)
  - DELETE VP removes orphan PendingUpload rows + upload_dir from disk
  - Per-VP cert regenerates on shared-CA rotation (real signature verification, not DN match)
  - DHCP target-IP refresh + queue_force_color_match toggle now restart proxy VPs
  - Per-slicer bridge-response routing (multi-slicer cross-leak fix via sequence_id map)
  - Child-service readiness barrier (FTP / MQTT / Bind / SSDP) — no false is_running before sockets bind
  - H2D Pro O1E / O2D model codes added (experimental, needs field confirmation)

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 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.

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 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 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 ca08f1f340 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 22f222e4ac 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.

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 3b9633a178 ● feat(support): include sanitized connection / VP / log-health diagnostics in support bundle and bug report (#1506 follow-up)
The three diagnostic surfaces shipped earlier this month
  (6bc6a1d6 VP setup diagnostic, e222a0ef log-health scanner,
  ed31b8f4 connection diagnostic in the bug-report bubble) were
  only ever shown to the *user*. A bug report arriving in the
  maintainer's inbox carried raw logs but no diagnostic results —
  the user-visible "your X1C can't reach MQTT" finding never made
  it into the issue body, so the maintainer had to ask the user
  to re-run and paste.

  New `services/diagnostic_snapshot.collect_diagnostic_snapshot`
  runs all three concurrently with a per-probe 15 s wall-clock cap
  (so total ≈ max(per-cap), not sum — fleet size doesn't matter)
  and is fail-soft per probe: a crash inside one printer's check
  emits `{"printer_id": N, "error": "..."}` for that entry rather
  than nuking the whole snapshot. The snapshot is then added as a
  `diagnostics` top-level key by `_collect_support_info()`, so both
  flows (POST /support/bundle and POST /bug-report/submit via
  `support_info=...`) pick it up without their own changes.

  Private-data sanitization
  -------------------------
  The diagnostic schemas embed raw IPv4 in five field shapes that
  must not land in a submitted GitHub issue or a shared support ZIP:

    - PrinterDiagnosticResult.ip_address (top-level)
    - DiagnosticCheck.params.printer_ip (network-mode check)
    - DiagnosticCheck.params.host_ip (network-mode check)
    - VPDiagnosticResult per-check params.bind_ip (VP setup)
    - IPs embedded in log-health sample lines

  The first two carry the printer's own IP (already in the
  existing `collect_sensitive_strings` table via the Printer rows);
  host_ip and bind_ip are NOT in the DB so a sensitive_strings-only
  pass missed them.

  Fix: `_sanitize_recursive` walks the full snapshot tree, masks
  DB-known values with the same `[PRINTER]/[IP]/[SERIAL]/[ACCESS_CODE]`
  labels the log sanitizer applies (via the shared
  `collect_sensitive_strings`), then an IPv4-regex pass catches any
  IP the DB didn't cover — most importantly the Bambuddy host IP
  returned by `_get_host_ip()` and the VP `bind_ip` the user picked
  at setup. Recursive walk so arbitrary nested dicts/lists don't
  slip through future schema additions.

  Live-DB smoke test against the dev fleet: zero raw IPv4 instances
  in the serialized snapshot output; all five field shapes plus the
  embedded log samples render as `[IP]`.

  Progress indicators
  -------------------
  The bubble's "submitting" view and the System page's Download
  button now render a static four-line checklist showing what's
  running (printer connectivity → VP setup → log scan →
  submit / build ZIP). Static, not faked phase progress — we can't
  actually track server-side phases without SSE and the honest
  "here's what's happening" list communicates the longer wait
  without lying about percentage complete.

  9 new i18n keys, real translations in all 9 locales (no English
  fallback). parity script clean at 4993 leaves per locale.

  Tests: 6 new in test_diagnostic_snapshot.py
    - empty-input shape stable (the three top-level keys always present)
    - per-printer / per-VP result coverage (lists match input lengths)
    - fail-soft on a single-probe crash (other entries + log-health
      still complete)
    - timed_out marker when a probe exceeds the per-probe cap
      (test patches the cap to 0.05 s)
    - end-to-end IP sanitization across all five field shapes plus
      log-sample IPs, with a final JSON-serialize-and-regex sweep
      asserting zero raw IPv4 escapes anywhere in the result
    - concurrent execution proof (4 × 0.2 s probes complete in
      < 0.5 s; sequential would be 0.8 s)

maziggy 03896d1af0 fix(scheduler): use inventory weight for "Prefer Lowest Filament" sort (#1508)
Reporter has a P1S with an inventory spool cloned to slot 1 and the
  original (much further used) in slot 4, the preference enabled, and
  the dispatch picked slot 1 every time. The sort's been blind to
  Bambuddy inventory weights — it reads MQTT `tray.remain`, the
  printer firmware's RFID-decremented value, which has two limitations:

  - Bambu RFID only. Non-RFID spools report -1 and get clamped to a
    sentinel; multiple non-RFID trays then tie in the sort and Python's
    stable sort collapses to AMS-slot insertion order, so slot 1 wins.
  - Even when set, it's the printer's counter, not Bambuddy's
    `label_weight - weight_used` (internal) or Spoolman's
    `remaining_weight`. The two diverge whenever the user re-spools,
    swaps cardboard, or runs a print outside Bambuddy.

  The reporter is on internal-inventory mode with non-RFID spools — both
  failure modes apply, hence slot 1 every time.

  Fix: when a slot is bound to an inventory spool the inventory record's
  remaining weight becomes the sort signal. New async helper
  `_build_inventory_remain_overrides(db, printer_id, loaded)` returns
  `{global_tray_id: remaining_grams}` for bound slots — internal mode
  joins SpoolAssignment → Spool once per dispatch; Spoolman mode joins
  SpoolmanSlotAssignment then reuses `_spoolman_remaining_grams` from
  filament_deficit.py for parity.

  New `_prefer_lowest_sort_key` does a two-tier comparison: inventory-
  tracked spools sort BEFORE MQTT-only spools, then ascending by
  remaining within each tier, then ascending by ams_id*4+tray_id as the
  deterministic slot tie-breaker. The tier flag dominates so grams
  (inventory) and percent (MQTT) never get cross-compared — no unit
  conversion needed.

  MQTT-only behaviour is preserved exactly: remain=-1 still maps to the
  101 sentinel and slot order still decides on ties. Users who haven't
  bound any inventory spool see no change. The DB lookup runs only when
  prefer_lowest_filament is enabled.

  External / VT slots are skipped (tracked separately from AMS bindings).

maziggy eae96da56e fix(camera): probe ffmpeg for the right RTSP socket-timeout flag (#1504)
A previous attempt swapped `-timeout` → `-stimeout` unconditionally to
  fix EADDRINUSE on the reporter's transitional ffmpeg. That broke every
  install on a modern ffmpeg (5+/6+/7+) — current Debian/Ubuntu/Homebrew
  — where `-stimeout` was removed and `-timeout` is back to meaning
  socket I/O. Verified locally: `ffmpeg -stimeout ...` errors
  "Unrecognized option 'stimeout'" on ffmpeg 7.1.
  install on a modern ffmpeg (5+/6+/7+) — current Debian/Ubuntu/Homebrew
  — where `-stimeout` was removed and `-timeout` is back to meaning
  socket I/O. Verified locally: `ffmpeg -stimeout ...` errors
  "Unrecognized option 'stimeout'" on ffmpeg 7.1.

  ffmpeg has shipped THREE arrangements of this option over time and
  Bambuddy supports the full range:

  - Pre-deprecation (early 4.x and earlier): `-timeout` is socket I/O.
  - Transitional (~late-4.x, Jammy-era): `-timeout` is deprecated and
    repurposed to RTSP listen-mode timeout; any non-zero value implies
    `-listen`, which makes ffmpeg bind the TLS-proxy port and fail with
    EADDRINUSE. `-stimeout` is the replacement socket I/O option.
  - Modern (5.x / 6.x / 7.x): `-stimeout` REMOVED. `-timeout` is back to
    socket I/O — the original meaning.

  So no single literal is correct on all installs.

  Fix: `rtsp_socket_timeout_flag()` in services/camera.py probes
  `ffmpeg -h demuxer=rtsp` once and picks `-stimeout` when ffmpeg
  advertises it (covers transitional + older builds that kept it as an
  alias), else `-timeout` (modern + pre-deprecation). Cached at module
  level for the process lifetime — ffmpeg doesn't swap mid-run.

  The function returns the option name without a leading dash; callers
  prepend it themselves so a formatting bug can't pass an empty flag.

  Wired into both RTSP ffmpeg call sites in lockstep: routes/camera.py
  (printer camera) and services/external_camera.py (external RTSP),
  which use the same TLS-proxy + ffmpeg pattern and would hit the same
  regression on either ffmpeg cohort.

  Tests: 8 in test_ffmpeg_rtsp_timeout_flag.py — 6 probe unit tests
  (prefers stimeout when advertised, falls back to timeout on modern,
  defaults to timeout when ffmpeg missing or probe raises, caches across
  calls, trailing-space substring guard against `-listen_timeout`
  false-positives), 2 parametrised guards against either RTSP ffmpeg
  argv re-hard-coding a literal instead of consuming the probe. 37
  probe + existing external-camera tests green.

maziggy ed08ed3787 fix(timelapse): capture baseline on restart-recovery so post-reboot timelapses attach (follow up issue #1485)
When Bambuddy is restarted mid-print, the first MQTT push from the
  printer carries `_previous_gcode_state = None`. The #1304 guard
  deliberately suppresses on_print_start on that first push to prevent
  duplicate archive creation — but on_print_start is also where
  _capture_timelapse_baseline_at_start runs, so the in-memory
  _timelapse_baselines dict stays empty for the resumed session.

  At PRINT COMPLETE, _scan_for_timelapse_with_retries finds no baseline
  and falls into its "take baseline now" fallback. By that point the
  printer has already uploaded the in-flight MP4, so the snapshot
  includes the new file. Every "Found N files / no new files since
  baseline" retry then fails to detect a diff, and the archive ends up
  with no timelapse attached — pwostran's report (#1485 follow-up): card
  shows the finish snapshot but no video.

  Add a sibling callback on_print_running_observed that bambu_mqtt fires
  in the "Now tracking RUNNING state" branch when on_print_start was
  suppressed. main.py wires it to a thin handler that looks up the
  printer row and calls the existing _capture_timelapse_baseline_at_start.
  Idempotent — skips if a baseline already exists (handles the rare
  same-session race where on_print_start also fires for some reason).

  The printer doesn't upload the timelapse until after PRINT COMPLETE,
  so a baseline captured any time during the print is still pre-upload —
  no narrow window to hit.

  Verified against the in-the-field logs in #1485 (pwostran's 2026-05-23
  support bundle):
    pre-reboot: baseline = 7 files
    reboot
    post-reboot completion: fallback baseline = 8 files (includes new MP4)
    -> all 4 retry attempts report "no new files since baseline"

  10 new tests cover both the MQTT-side fire decision (fires when
  suppressed, doesn't fire when on_print_start handles it, once per
  session, payload shape mirrors on_print_start) and the main.py
  handler (snapshot capture, double-capture guard, missing-printer-row
  guard).

maziggy c0c07bc509 fix(archives): cross-model re-slice no longer carries source printer_id
When the user re-sliced an H2D archive for X1C, the new archive card and
  reprint modal both showed the source printer's name (e.g. "Workshop H2C")
  even though sliced_for_model on the same row correctly read "X1C".

  slice_and_persist_as_archive copied source_archive.printer_id verbatim
  onto the new PrintArchive row. Both the archive card
  (ArchivesPage.tsx:3571) and the reprint modal read printer_id first and
  only fall back to sliced_for_model when it's None. With printer_id set
  to the source's H2D printer, neither could see that the new file is for
  a different model.

  Same shape as the sliced_for_model fix already in the same function — a
  cross-model re-slice means the source's physical printer isn't where
  this output prints anymore. When the slicer-baked target model differs
  from source_archive.sliced_for_model, drop printer_id so both surfaces
  fall back to the sliced_for_model badge ("X1C"). Same-model re-slices
  keep printer_id so the reprint modal still pre-selects the source
  printer.

  Edge case: when source_archive.sliced_for_model is None (older archives
  that predate that column being populated), we can't tell whether this
  is a cross-model re-slice. Fail open and preserve printer_id rather
  than spuriously nulling it.

  slice_and_persist (the library-file path) doesn't have this bug —
  LibraryFile has no printer_id column.

  Tests in TestSliceArchiveResliceModel cover all three branches: cross-
  model nulls printer_id; same-model keeps it; unknown source model
  preserves it.

  Surfaced via the bambuddy demo doing H2D -> X1C re-slices after the
  .bbscfg System-tier slicing fix landed.

maziggy 3058c5789b fix(slice): @BBL name fallback for users without slicer bundles (#1325 follow-up)
The first cut of #1325 swapped a stale hardcoded model table for
  bundle-based compatibility matching: a cloud / standard process or
  filament preset was classified by consulting the user's uploaded
  Slicer Bundles (.bbscfg). That works perfectly when bundles cover
  every printer in the user's cloud catalogue, and silently no-ops
  otherwise - every cloud preset resolves to 'unknown', nothing moves
  into "Other printers", and the dropdowns look identical to the
  pre-fix state. The reporter saw exactly this on a clean install
  with no bundles uploaded.

  Restored BambuStudio's `@BBL <token>` name convention as a third
  tier below the bundle path, but driven by the canonical backend
  PRINTER_MODEL_MAP - exposed via a new GET /slicer/printer-models
  route - rather than a manually-maintained frontend table. The
  matcher inverts the registry into short-code -> printer-fragment
  ("X1C" -> "X1 Carbon"), normalises whitespace + case so "A1 mini"
  and "A1 Mini" compare equal, and falls back to raw-token compare
  for models not yet in the registry (so a future "Q1" matches
  without a code change). Adding a new Bambu model still touches
  exactly the one backend file already listed in the Bambu Model
  Codes registry.

  Tests: 2 new in test_slicer_presets.py (route returns the full
  PRINTER_MODEL_MAP, route returns a copy not the live dict); 11
  new in slicerPrinterMatch.test.ts covering registry-driven X1C
  vs X1 Carbon, A1 vs A1 mini, H2D vs H2D Pro, P2S / H2C / H2S /
  X2D (which the original hardcoded list was missing), raw-token
  fallback, registry-not-loaded-yet degradation, and the
  precedence rules between compatible_printers / bundle / @BBL
  name. 38 slicer-presets + 36 slicerPrinterMatch + 34 SliceModal
  tests green; backend ruff clean; frontend build clean.

maziggy 4096d8d6bd fix(csp): nonce-based script-src so Cloudflare-injected scripts pass (#1460 follow-up)
Behind Cloudflare, the bot-detection script CF injects into every HTML
  response carries a hash that rotates per request, so it can never be
  allowlisted by hash. Reporters with CF in front had to relax their NPM
  CSP to 'unsafe-inline' as a workaround.

  Per Cloudflare's documented behaviour, when a nonce is present in the
  page's script-src, CF clones it onto its injected <script>. The SPA CSP
  now stamps a fresh per-request nonce via secrets.token_urlsafe(16),
  keeping 'self' for our own scripts (index.html has had no inline scripts
  since the SW registration moved to /sw-register.js in the original
  #1460 PR), so no HTML body rewriting is needed.

  Also folded in: /manifest.json, /sw.js and /sw-register.js now accept
  HEAD as well as GET, so `curl -I` and uptime scanners stop returning
  405 on those routes - a separate red herring during this issue's
  debugging.

  Tests: 3 new in test_security_headers.py - 'nonce-' token stamped into
  SPA script-src while 'self' remains and 'unsafe-inline' does not; nonce
  is fresh per request across 5 sequential calls; HEAD on the three PWA
  routes never returns 405. 22/22 security-header tests green; backend
  ruff clean.

maziggy 4686d108ef feat(slice): cross-printer re-slicing across nozzle classes + multi-plate slice-all
Re-slicing a 3MF authored for a single-nozzle printer (X1C, P1S, A1, P2S)
  onto a dual-nozzle printer (H2D / H2D Pro) — or vice versa — previously
  failed with "G-code in unprintable area of multi-extruder printers" (the
  source's bed-coordinate layout lands in the H2D's per-nozzle dead zone)
  or, on multi-color projects, a hard SIGSEGV inside the slicer's ZFiller
  polygon-clipping. Earlier shipped a fail-fast 400 guard; this drop lifts
  it and actually does the conversion by forwarding the sidecar's existing
  --arrange flag when the source and target nozzle classes differ. BS
  itself reconciles the embedded project_settings.config against the new
  printer that way, the same way the GUI's "Switch Printer" operation
  does. The guard becomes a kept-for-compat no-op.

  Slice-all-plates added to the SliceModal: a checkbox for multi-plate
  sources sends plate=0 to the backend, which forwards --slice 0 to the
  BS CLI. Same-class slice-all produces one multi-plate output 3MF in a
  single sidecar call. Cross-class slice-all loops per plate (BS's
  --arrange is project-wide and would otherwise consolidate every plate's
  objects onto one bed) and merges the per-plate outputs into one
  multi-plate 3MF locally via the new merge_plate_3mfs helper. The toast
  shows "Plate 2 of 5 — Generating G-code (47%)" through the loop.

  Three side fixes surfaced during testing:
  - substitute_unused_plate_filaments overwrites unused-slot filaments
    with the slot-1 selection before slicing so BS's loaded-filament
    temperature validator doesn't reject a PLA print whose unused slot 2
    defaulted to ABS in the dropdown
  - re-sliced archive thumbnail now prefers the source's per-plate
    render (Metadata/plate_N.png) over the project-wide MakerWorld cover
    art, because BS CLI with --arrange skips writing a fresh per-plate
    preview
  - re-sliced archive bed_type now lifts from the sliced output's
    curr_bed_type onto the PrintArchive column the card actually reads

  Schema: SliceRequest.plate range relaxed from ge=1 to ge=0 to admit
  the "all plates" sentinel; SlicerApiService.slice_with_profiles /

maziggy 7ea4410b21 fix(queue): insufficient-filament warning now fires on every dispatch path (#1496)
The pre-print deficit warning from #720 only ran inside the PrintModal
  submit flow. Both the green ▶ button on a staged queue row (POST
  /queue/{id}/start) and the Virtual Printer queue-mode intake bypassed
  it — auto_dispatch=True VP intakes would dispatch unsupervised onto
  spools that physically can't complete the print.

  Extracted the deficit check into backend/app/services/filament_deficit.py
  (single source of truth, both internal inventory and Spoolman modes).
  POST /queue/{id}/start returns 409 with a structured deficit payload
  unless ?skip_filament_check=true. The dispatch scheduler runs the same
  check before each _start_print; a deficit promotes the item to
  manual_start + sets a new filament_short flag (idempotent migration on
  print_queue). The flag clears automatically on the next tick when the
  operator swaps a spool to one with enough material.

  Frontend ▶ catches the 409 and opens a confirm modal showing each
  shorted slot's required vs remaining grams; the row now renders a
  yellow "Insufficient filament" badge when filament_short is set.
  Translated across all 9 locales.

maziggy e222a0ef0e feat(system): log-health scanner + Add/Edit-Printer setup pre-flight
Adds a passive log-health check that complements the active Connection
  Diagnostic. Scans Bambuddy's recent app log against a curated allowlist
  catalog of known failure signatures (rejected access code, FTPS :990
  timeout, FTPS TLS failure, flapping MQTT, unreachable camera, SQLite
  "database is locked" contention), dedupes and classifies each finding
  as layer8/environment/bug, and deep-links to the troubleshooting wiki.
  Sample log lines are sanitized before they leave the process. Exposed
  via GET /system/health and surfaced on two surfaces sharing one
  SystemHealthPanel component: a System Health section on the System
  page, and inline in the bug reporter when the form opens.

  The Add-Printer and Edit-Printer dialogs gained a setup-time pre-flight:
  saving runs the connection diagnostic and, on a failed check, warns with
  a "save anyway" escape hatch instead of silently saving a printer that
  will immediately show offline.

  Log read/parse/sanitize primitives extracted from routes/support.py into
  a shared services/log_reader.py (behaviour-preserving); affected support
  tests repointed accordingly.

  Tests: test_log_health.py (11), test_system_api.py (2 new),
  SystemHealthPanel + BugReportBubble + AddPrinterPreflight +
  EditPrinterPreflight (8 frontend). All strings translated across the 9
  locales. Backend ruff clean, full unit suite green, frontend build +
  eslint clean, i18n parity green.

maziggy ab8e07618f fix(inventory): archive filament colour follows the assigned spool, not the 3MF (#1494)
An archive's filament_color was parsed verbatim from the print job's
  3MF (filament_colour in project_settings.config) — the slicer's
  filament-slot colour, which a user picks independently of the exact
  hex they curate on the Bambuddy inventory spool. So a print from a
  #000000 inventory spool showed #161616 (the slicer's near-black) in
  the archive card and the Color Distribution graph, even though usage
  tracking correctly decremented the right spool.

  Once usage tracking has resolved the print's filament slots to
  inventory spools, the spool colours are authoritative. _track_from_3mf
  (built-in inventory) and report_usage (Spoolman mode) now overwrite
  the archive's filament_color with the slot-ordered, de-duplicated
  colours of the matched spools.

  The rewrite is all-or-nothing: it only applies when every used slot
  resolved to a spool carrying a colour, so a partially-mapped
  multi-colour print keeps the 3MF colour rather than silently dropping
  the unmatched slots.

  Shipped for both inventory modes: built-in spools read Spool.rgba,
  Spoolman spools read the spool's filament.color_hex (fetched via
  get_spool for tag-less slot-assignment matches). New helpers
  _spool_color_to_hex / _archive_colors_from_spools in usage_tracker.py,
  reused by spoolman_tracking.py via _apply_spool_colors_to_archive.

  Tests: 12 new in test_usage_tracker.py (hex normalisation, the
  all-or-nothing rule across single/multi/partial/no-colour/AMS-fallback
  cases, end-to-end rewrite), 4 in test_spoolman_tracking.py (Spoolman
  rewrite + empty/partial/missing-archive no-ops). 70 tracking tests
  green; backend ruff clean.

maziggy 6d7a92c024 fix(camera): P2S RTSP stream dropped every frame after the first (#1395)
A fresh P2S support bundle showed ffmpeg's reason for the stall:
  `frame=1 time=00:00:00.06 dup=0 drop=526 speed=0.0037x`. ffmpeg
  connects and frames arrive (drop counter climbs ~15/s), but it emits
  one output frame and the output clock freezes.

  The streaming command ends with `-r 15`, putting ffmpeg in CFR mode:
  it drops/dupes input frames to hit 15 fps based on the source's
  timestamps. P2S firmware 01.02.00.00 sends an RTSP stream whose RTP
  timestamps don't advance, so CFR treats every frame after the first
  as a same-timestamp duplicate and drops it. Snapshot capture works on
  the same printer because that path has no `-r` (no CFR conversion);
  X1/H2 are unaffected because their firmware timestamps are correct.
  The earlier probesize fix was masking this second bug.

  Add `-use_wallclock_as_timestamps 1` to the P2S camera profile via
  the existing extra_ffmpeg_input_args hook. ffmpeg rebuilds each
  packet's PTS from arrival wall-clock time, the output clock advances,
  and CFR conversion works. No dataclass change, no other model touched.

  Tests: 2 new in test_camera_profiles.py (P2S splices the flag+value
  pair; default profile keeps extra_ffmpeg_input_args empty so the
  override never leaks to X1/H2).

maziggy 6bc6a1d683 feat(virtual-printer): setup diagnostic + one-click slicer-certificate export
Two recurring virtual-printer support pains, both on the Virtual Printers
  settings page.

  Setup check: a stethoscope action on each VP card runs a pass/fail/warn/skip
  checklist — VP enabled, services running, bind interface still exists, access
  code set, target printer (proxy mode), and a live TCP probe of the FTP / MQTT
  / discovery ports on the bind IP. start_server swallows per-service bind
  errors, so a service object can exist while nothing is listening; probing the
  bind IP from outside is the only reliable signal and it catches the common
  "VP not visible in the slicer" bind-IP-conflict and stale-interface cases.

  Slicer certificate: virtual printers present a TLS cert signed by a shared CA
  the slicer must trust. Until now users had to docker exec in and cat
  bbl_ca.crt. A "Slicer certificate" row on the settings card now offers Copy
  and Download (bambuddy-virtual-printer-ca.crt) plus the SHA-256 fingerprint.
  GET /virtual-printers/ca-certificate returns only the public certificate; the
  CA private key never leaves the backend. The CA is generated on demand so the
  button works before the first VP is enabled.

  Backend:
  - services/virtual_printer/diagnostic.py — run_vp_diagnostic + port probes
  - schemas/virtual_printer.py — VPDiagnosticResult
  - CertificateService.get_ca_certificate_info() + manager helper
  - routes: GET /virtual-printers/ca-certificate, /{vp_id}/diagnostic

  Frontend:
  - VirtualPrinterDiagnosticModal.tsx; stethoscope button on VirtualPrinterCard
  - caCert row on VirtualPrinterList; utils/clipboard.ts (shared copy w/
    non-secure-context fallback + downloadTextFile), de-duplicating the
    existing FQDN-copy logic
  - vpDiagnostic.* + virtualPrinter.caCert.* across all 9 locales

  9 backend unit tests + 4 route integration tests + 6 frontend tests.
  Backend ruff clean, frontend build clean, i18n parity green.

maziggy 4925b4c830 fix(slice): re-slice correctness — model label, honest errors, filament usage, nozzle guard
Five follow-up fixes to cross-printer re-slicing, all surfaced while
  testing archive re-slices.

  1. Re-sliced archive now records the printer it was sliced FOR.
     slice_and_persist_as_archive copied sliced_for_model from the source
     archive, so re-slicing X1C->H2D still showed "X1C sliced". Read it
     from the freshly-sliced 3MF's parsed metadata instead, falling back
     to the source only when absent.

  2. Real slicer rejections are surfaced instead of silently masked.
     _run_slicer_with_fallback retried with the 3MF's embedded settings on
     any sidecar 5xx — including genuine content rejections (object off
     the bed, incompatible filament temps), which "succeeded" only by
     re-slicing for the source's original printer. A new
     _slicer_rejection_message detects the slicer's own error string and
     surfaces it as a 400; the embedded-settings fallback is kept only for
     true CLI crashes.

  3. A failed slice opens an error modal, not a 3s toast. The slicer's
     reason is actionable and a toast hides it before it can be read. New
     AlertModal (acknowledge-only); SliceJobTrackerContext shows it on a
     failed job. New slice.failedTitle key in all 9 locales.

  4. Sliced files no longer report "0 g" filament usage. The sidecar
     doesn't always populate the X-Filament-Used-* headers;
     ThreeMFParser._parse_gcode_header now also reads the slicer's own
     "total filament weight/length" from the G-code header, and both
     slice-persist paths fall back to it when the sidecar reports 0.

  5. Nozzle-class re-slice guard. Re-slicing across the single-nozzle <->
     dual-nozzle boundary (e.g. X1C -> H2D) fails BambuStudio's
     multi-extruder validation; both slice routes now reject it up front
     with a clear 400. The dual-nozzle model classification — previously
     an inline tuple duplicated across start_print and the K-profile
     routes — is centralized into DUAL_NOZZLE_MODELS / is_dual_nozzle_model
     in printer_models.py, consumed by all three sites and the guard.

  Full cross-nozzle-class re-slicing (dual-nozzle project_settings
  reconciliation) remains separately tracked.

  Tests: _slicer_rejection_message, _canonical_printer_model,
  guard_nozzle_class_reslice, is_dual_nozzle_model, the G-code-header
  filament parse, AlertModal, and end-to-end slice-API coverage including
  an X1C-archive-to-H2D 400. Backend ruff + i18n parity clean; frontend
  build clean.

maziggy 16da533c9a fix(static): serve /fonts/*.woff2 — self-hosted Inter font (#1460 follow-up)
The browser console logged "downloadable font: rejected by sanitizer"
  for inter-latin.woff2 on every load. The #1460 PWA fix added @font-face
  rules pointing at /fonts/inter-latin.woff2 and bundled the woff2 files
  into static/fonts/, but main.py only mounts /assets, /img and /icons as
  static directories. With no /fonts mount, /fonts/*.woff2 fell through to
  the SPA catch-all and returned index.html with 200 OK; the browser's
  OpenType sanitizer rejected the HTML-as-a-font.

  Add a /fonts StaticFiles mount alongside /img and /icons. The woff2
  files themselves are valid (verified — Inter variable, latin and
  latin-ext subsets).

  Also bump the service worker STATIC_CACHE version (v26 -> v27). sw.js
  lists the two font URLs in STATIC_ASSETS, and cache.addAll() treats the
  200 OK HTML as a successful fetch — so it had cached index.html under
  the font URLs and served it cache-first. The version bump makes the
  activate handler purge the poisoned cache and re-fetch the real fonts.
