Slicing an STL via the integrated slicer always defaulted to whatever
curr_bed_type lived in the chosen process preset (typically "Cool
Plate"), which the slicer CLI rejected for high-temp filaments with
"Plate 1: Cool Plate does not support filament 1". The user had no
way to switch plates without cloning the preset in BambuStudio.
The Slice modal now exposes a Build plate dropdown with the six
canonical BambuStudio / OrcaSlicer plates (Cool Plate, Cool Plate
SuperTack, Engineering Plate, High Temp Plate, Textured PEI Plate,
Smooth PEI Plate) plus an "Auto (use process preset)" option that
preserves the previous behavior. Positioned between Process profile
and Filament rows so a long filament list never pushes it off the
modal's scrolled viewport, and always enabled regardless of whether
the user picked a Printer Preset Bundle.
A new bed_type field on SliceRequest flows through both dispatch
paths:
- Resolved-preset path: _patch_process_bed_type overwrites
curr_bed_type on the process JSON before forwarding to the sidecar.
Works end-to-end today, no sidecar change needed.
- Bundle dispatch path: slice_with_bundle adds a bedType form field
to the sidecar multipart. The sidecar (maziggy/orca-slicer-api
fork) needs a matching change to honor it as --curr_bed_type on
the CLI invocation; until then the field is silently ignored and
the slice runs with the bundle's default plate.
Bambuddy's external SpoolmanDB lookup in `_find_or_create_filament` matched
on material+color only, with no manufacturer filter. Because SpoolmanDB is a
multi-vendor catalog and entries are roughly ID-sorted, the first hit for
any common combination is almost always a competitor — `bambulab_pla_black_1000_175_n`
is the 15th entry for PLA + `#000000`. Bambu Lab RFID spools were being
labeled with competitor product names (`3DJAKE Black`, `3DXTECH™ Black`, etc).
Restrict the external-library loop to entries whose manufacturer is
`"Bambu Lab"` (with `id.startswith("bambulab_")` as a defensive fallback
for schema drift). When multiple Bambu Lab candidates exist, prefer the
entry whose `name` equals the AMS `tray_sub_brands` so `"PLA Basic"` wins
over generic `"Black"` when both are present. Forward `density` from the
chosen external entry so it is no longer overwritten by the PLA-default
1.24 in `create_filament`.
Six unit tests added: internal short-circuit preserved, non-Bambu external
entries skipped, PLA Basic > generic PLA tiebreaker, no-match fallback,
id-prefix defensive fallback, density propagation.

On A1 / A1 Mini, clicking the "Up" arrow on the printer-card bed-jog
control sent the nozzle straight into the build plate. Reporter
triggered it with the 50 mm step and crashed their nozzle.
Root cause: the bed-jog UI was designed against the X1 / P1 / H2 family
where the bed is the Z-axis and Bambu's firmware homes Z=0 at the top,
so G1 Z- raises the bed toward the toolhead (decreases the nozzle-bed
gap). The frontend maps "Up" to negative distance with that convention
in mind.
A1 / A1 Mini are bed-slingers: bed moves on Y, toolhead moves on X+Z,
firmware uses standard cartesian Z (Z+ = toolhead up). On those models
G1 Z-10 drives the toolhead DOWN 10 mm. There was no model
classification at the bed-jog code path, so every printer got the same
X1-convention G-code.
Fix: new is_bed_slinger(model) helper in printer_manager (sibling to
existing supports_chamber_temp / has_stg_cur_idle_bug, reuses the
already-defined A1_MODELS frozenset which covers display names and
internal codes N1 / N2S). The bed-jog route now inverts the signed
distance before emitting G-code when the printer model is in that set,
so UI "Up" semantics ("decrease nozzle-bed gap") stay consistent
regardless of which physical part moves. Frontend untouched, single
source of truth lives in the backend, keyed off the Printer.model
column. Route Query description and docstring updated to spell out the
new contract: distance is the gap adjustment, not the raw Z value.
Editing a spool's color name on Spoolman-backed inventory appeared to
accept the new value but the inventory list column and the next edit
showed it back to the subtype. Three layers stacked to produce this:
1. find_or_create_filament matches by material/name/color_hex/vendor —
color_name is intentionally not part of the match key, but on a
match it returned the existing filament's id unchanged, silently
dropping the new value.
2. The read helper falls back to subtype when filament.color_name is
empty (kept on purpose: without it Spoolman installs that don't
fill the field render every spool as "Unknown color").
3. The edit form prefilled color_name from spool.color_name — which
on those installs was the synth value. Changing subtype but not
color_name silently round-tripped the OLD subtype back to Spoolman
as if it were a real user-set color_name.
Fixes:
- find_or_create_filament now patches the matched filament's
color_name via the existing patch_filament wrapper when the request
differs. Parameter convention: None = don't touch, "" = explicit
clear, any other string = set/update. A patch failure is logged but
does not block the match.
- The PATCH route uses model_fields_set to distinguish "field omitted"
from "field explicitly set to null" (mirrors the existing
storage_location pattern at the same site).
- The map helper returns color_name_is_synthesized: bool. The edit
form leaves the input blank when true, so the user sees the real
stored state and can't accidentally round-trip the synth value back.
fix(auth): cleanup orphan OIDC/MFA rows on user delete (#1285)
Three User-FK tables (user_oidc_links, user_totp, user_otp_codes)
declare ON DELETE CASCADE in their models, but SQLite ships with
PRAGMA foreign_keys=OFF (the project's existing pattern, mirrored
for APIKey in PR #1182). Without explicit DELETEs, deleting a user
on SQLite leaves orphan rows behind:
Issue #1312 follow-up. Investigation traced the "Name cannot be empty"
report to a sidecar image pre-dating the /profiles/bundle endpoint
addition. Two changes so the next occurrence is self-diagnosable from
the support bundle without a manual curl.
Backend: new _fetch_slicer_health(url) helper does a 2s GET on /health,
walks every non-dataPath key under checks looking for a version field
(the wrapper labels both sidecars as checks.orcaslicer regardless of
which CLI is bundled). _collect_slicer_api_info now exposes
bambu_studio_version and orcaslicer_version. Strips trailing slash
before appending /health to avoid double-slash 404s.
Docs: bambuddy-wiki/docs/features/slicer-api.md gains a Quick Start
callout that branch-built sidecars don't auto-update, a corrected
/health troubleshooting entry (both "unknown" version and "orcaslicer"
field name on bambu-studio-api are cosmetic wrapper bugs, not stale-
image indicators), a new "Name cannot be empty" troubleshooting entry,
and an Updating section that requires --no-cache --pull together
(BuildKit caches the git context separately from layers, so --no-cache
alone silently reuses the old checkout).
The route mapped sidecar 4xx/5xx to HTTPException with detail but never
logged it. Reporters seeing a 400 toast were giving us only the status
code, not the reason, and the access-log line was all that landed in
support bundles.
Add WARNING-level logs on each error branch (400 SlicerInputError,
503 SlicerApiUnavailableError, 502 SlicerApiError) with the sidecar's
own message + the filename / byte count / configured URL. Next reporter
on this code path produces a support bundle that contains the answer.
The settings-table passthrough auto-captured everything in `settings` (with
sensitive-key redaction), but features storing config in dedicated tables
were invisible. Triaging recent OIDC / 2FA / group bugs and the X1C slicer
investigation needed data that wasn't in the bundle.
New blocks in _collect_support_info:
- auth: OIDC providers (cleartext names, no secrets), TOTP / OTP /
API-key / long-lived-token / group counts
- library: file / folder / external / trash / makerworld totals
- inventory: spool + k-profile counts
- queue: pending count, oldest pending age
- maintenance: items total + enabled
- integrations.github_backup: providers used + recent failures
- integrations.slicer_api: enabled, URL source, reachability ping
- per-printer obico_enabled flag
Plus three smaller fixes caught testing against a real bundle:
- mqtt_broker no longer leaks (broker keyword added)
- virtual_printer_tailscale_auth_key no longer leaks (auth_key keyword
+ tskey- value-prefix safety net for future Tailscale settings)
- slicer-API reachability check now mirrors the route's three-level URL
precedence (DB → env var → default), instead of only looking at the
DB setting. Previously returned null for every installation running
the sidecar via env var or default port — i.e. most of them.
Restarting Bambuddy mid-print misfired the plate-check + archive flow.
The is_new_print guard treated _previous_gcode_state=None → RUNNING as
a transition, but None just means we haven't seen any prior state yet —
catch-up from a printer that was already running, not a fresh start.
Add `_previous_gcode_state is not None` to the guard. _was_running still
flips on unconditionally, so completion detection is unchanged. 3 tests
that asserted the buggy behavior now seed an explicit prior state; new
regression test pins the contract for the reporter's exact scenario.
External scan hung on a 1200-subdir NAS because (1) every STL crashed
with TypeError ('str / str') inside generate_stl_thumbnail and (2)
thumbnail generation ran synchronously per file, so the FE timed out
before db.commit() and nothing was persisted.
stl_thumbnail.py now coerces inputs to Path defensively, and
scan_external_folder defers STL thumbnail generation to a background
asyncio task that opens its own session and processes each file
post-commit. Subdirs appear in the sidebar immediately; thumbnails
backfill over the next seconds/minutes.
The column existed on the Spool ORM model but was missing from
SpoolBase, SpoolUpdate, and SpoolResponse. Pydantic silently
dropped writes and reads omitted the field, so the inventory
table always showed "—" in the Storage Location column even
after saving. Adding the field to the two schemas is enough —
the update route already uses model_dump + setattr.
Real-printer prints broadcast archive_created from the MQTT print_start
handler, which the Archives page listens for to invalidate its query
cache. The VP file-receive paths created the archive in the DB but
never emitted the event, so the new card only appeared after a tab
switch triggered refetch-on-focus.
Added a small _broadcast_archive_created helper on VirtualPrinterInstance
and called it from _archive_file (immediate mode) and _add_to_print_queue
(queue mode). Review mode is unaffected — it creates a PendingUpload,
not a PrintArchive. Broadcast errors are swallowed at debug level so a
transient WebSocket issue can't break the file-receive flow.
Bambuddy's VP supports two slicer flows: Send (file upload only — what
queue/immediate/review modes are designed for) and Print (file upload
+ start-print, intended for proxy mode). When a user clicks Print
against a non-proxy mode the VP must still respond gracefully — the
file is fine to receive, just the start-print never happens. Instead
the slicer wedged at "Downloading...(0%)" and blocked the next
dispatch with "The printer is busy with another print job".
Cause: on_file_received transitioned gcode_state PREPARE -> IDLE
directly. Print-flow slicers watch the state cycle and only release
their in-flight-job lock on PREPARE -> ... -> FINISH (or FAILED).
PREPARE -> IDLE looks like "printer abandoned my job" and keeps the
prior job pinned in the slicer's memory.
Fix: transition PREPARE -> FINISH with prepare_percent=100. The 1-Hz
periodic status push broadcasts the new state to every connected
slicer within a second. Send-flow slicers don't watch this state so
the change is a no-op for them; Print-flow slicers see the FINISH
they were waiting for and unwedge.
ams_set_filament_setting and reset_ams_slot encoded the single-external
case as {ams_id: 255, tray_id: 0, slot_id: 0}. The "LOCAL tray_id = 0"
comment was a misread of the printer's response (which echoes the local
slot position), not the request semantics.
Captured BambuStudio -> X1C exchange shows the request encoding is
{ams_id: 255, tray_id: 254, slot_id: 0} (global tray index in tray_id).
The previous code's tray_id: 0 is what the P1S in #1279 rejects with
result: "fail", which silently broke external-spool filament selection
on every Bambu printer with no AMS or external spool in active use.
Dual-external (H2D) branch was not in the captured exchange and is
explicitly pinned at the legacy encoding pending a Studio -> H2D capture.
scan_timelapse's Strategy 2 matched filename timestamps against both
archive.started_at and archive.completed_at across seven hypothesised tz
offsets. The filename is always print-START time, so the end-time branch
was a semantic mistake — and the dense offset set [0, +-1, +-7, +-8]
let an unrelated video coincidentally land within minutes of any later
archive at some offset.
Extract Strategy 2 into _match_timelapse_by_timestamp(): compare only
against start time, and refuse to auto-pick when the next-best different
video is within a 15-minute ambiguity margin. The route then returns
available_files and the frontend's existing manual-selection dialog
takes over — which is the fallback the reporter explicitly asked for.
Surfaces in LAN-Only mode where the printer can't reach NTP and its
clock drifts (e.g. P2S filenames in CST while server is in UTC, the
8h offset that exposed this bug).
BambuStudio encodes virtual tray IDs (254/255) as -1 in the flat
ams_mapping array — a convention already documented in
bambu_mqtt.py:start_print(). The spoolman tracking helper was treating
-1 as "unmapped, use position-based default", which mapped slot_id=1
to AMS tray 0 and credited external-spool prints to whatever Spoolman
spool happened to be linked to AMS slot 0. The reporter's TPU prints
on an H2S were credited to a PLA spool for ~49g over 4 prints before
being noticed (regression of #853).
When slot_to_tray[slot_id-1] == -1 and ams_trays contains 254/255,
return the external tray ID directly. Prefers 254 over 255 (matches
single-nozzle tray_now reporting + the vir_slot id=255->254 remap in
bambu_mqtt.py:864). Legacy fall-through preserved for callers that
don't pass ams_trays.
Root cause investigation and patch by @ojimpo.
Prints sent from a slicer to a VP in print_queue mode arrived in the
queue with bed_levelling / flow_cali / vibration_cali / layer_inspect /
timelapse set to the SQLAlchemy column defaults, ignoring the user's
workflow page settings entirely. The manual POST /print-queue endpoint
reads these from the request body (frontend pulls them from settings
before submitting), but manager._add_to_print_queue constructed the
PrintQueueItem without touching any of those fields.
Read default_bed_levelling and the other four settings via get_setting
and pass them explicitly. _bool_setting helper handles the None ->
AppSettings default fallback.
H2C / H2D AMS-HT units report ams_id 128+ (one ams_id per unit, single
tray), but spoolman_slot_assignments.ck_ams_id_range only admitted 0-7
and 255. Every attempt to link a Spoolman spool to an AMS-HT slot died
with `CHECK constraint failed: ck_ams_id_range`. The internal
spool_assignment table has no such constraint and works fine.
Widen the formula to (0-7) OR (128-191) OR 255 in the model, the
CREATE TABLE DDL, and an idempotent in-place migration for existing
installs (Postgres: DROP/ADD CONSTRAINT; SQLite: detect stale formula
in sqlite_master, rebuild via _v2 rename pattern).
The MJPEG fan-out broadcaster from #1089 only solved viewer-side
concurrency. Obico polling (every 5s) and the manual /camera/snapshot
endpoint kept opening their own fresh RTSP sockets, which X1/H2/P2
firmwares tolerated but X2D firmware 01.01.00.00 enforces strict
single-connection on — every poll kicked the live stream.
Add try_get_active_buffered_frame(printer_id): returns the broadcaster's
last buffered frame when a viewer is connected, None otherwise. Obico
and /camera/snapshot consult it before opening a fresh socket. When no
viewer is active they fall through to the existing fresh-capture path.
plate_detection and layer_timelapse intentionally not converted.
Spoolman had two mutually-exclusive weight paths gated on the
`disable_weight_sync` flag. The default (False) used AMS remain%
x tray_weight auto-sync, which silently dropped non-BL spools
because the AMS doesn't report tray_weight without RFID. The
inventory_remaining fallback would have covered it, but the
spool_assignment table it reads from is wiped on Spoolman
activation, so non-BL spools got no weight updates at all.
Match the internal Filament Inventory: per-print tracking always
runs, AMS auto-sync no longer writes remaining_weight (it still
maintains spool metadata and slot assignments). The setting
becomes a no-op; left in the schema and UI for backwards compat.
- store_print_data: drop the disable_weight_sync early return
- sync_ams_tray callsites in main.py + routes/spoolman.py: force
disable_weight_sync=True so weight is never written by AMS sync
- new regression test confirming tracking runs with flag=false
The AMS remain% delta path charged every tray with a delta, not just
trays involved in the print. Swapping a spool in an UNUSED slot mid-
print made the slot report remain=0 (fresh spool, no tag), versus a
print-start snapshot of 100%, so the originally-assigned spool got
charged the full 1000g.
Build print_used_keys from ams_mapping, tray_change_log, and
tray_now_at_start, and skip fallback for trays not in that set.
Legacy "scan every tray" behavior preserved when none of the three
signals are present.
The patch on printer_state_to_dict raced against the broadcast coroutine
under pytest-xdist's parallel workers. Mostly won locally, lost
occasionally on CI — surfaced first as AttributeError on .kprofiles,
then (after _fake_state was hardened) as a dict-content mismatch
between the patched return value and the real 36-key dict.
Fix: stop patching printer_state_to_dict; let it run for real against
the complete _fake_state stub. Assertions now check the broadcast fired
with the right printer_id and a dict containing awaiting_plate_clear,
not the exact dict shape — that decouples the test from
printer_state_to_dict's evolving body.
The two TestBroadcastStatusChange / TestEndToEndUnderRunningLoop tests
patch printer_state_to_dict to return a fixed dict, but on parallel
xdist runners (CI's pytest -n 30) the patch occasionally didn't catch
the call and the real function ran against the 4-field SimpleNamespace
fake — first attr access (.kprofiles) AttributeError'd, swallowed by
the try/except in _broadcast_status_change, send_status never awaited,
the assertion failed.
Filled _fake_state with every attribute the real printer_state_to_dict
reads (iterables empty, scalars None, stg_cur=0 for the int comparison
in get_derived_status_name). Test now passes whether or not the patch
lands.
feat(#1239): first cut at Gitea backups silently failing after 1st run
feat(#1239): Added Token Scope for Forgejo edge case. Also included: test coverage for fixes
Three enhancements requested by @oliboehm after the V1 label-printing
ship in #809:
- New box_40x30 single-label template (common DK/Brother roll size,
good for filament-bag and storage-bin labels). Routes through the
existing roomy layout since height >= 20 mm.
- Colour hex code (#RRGGBB, alpha-stripped, uppercase) rendered on
every label - useful when several near-identical material/colour
spools sit next to each other and the swatch alone isn't enough to
tell them apart. Skipped silently when rgba is None or malformed.
- Brand line bumped to Helvetica-Bold (was regular) and a couple of
points larger on both layouts so it reads cleanly at arm's length.
Wired through the SpoolLabelTemplate union, the modal's
TEMPLATE_OPTIONS, and the inventory.labels.templates.box40x30 i18n
key in all 8 locales (native translations for de/fr/it/ja/pt-BR/
zh-CN/zh-TW). Modal regression test widened from 4 to 5 template
buttons. Three new renderer tests pin the hex-code render, the
hex-code skip on invalid rgba, and the bold-brand font reference.
The kiosk's Settings -> Update Daemon button returned "API keys cannot
be used for administrative operations" because POST /spoolbuddy/devices/
{id}/update was gated on Permission.SETTINGS_UPDATE, and SETTINGS_UPDATE
is in the _APIKEY_DENIED_PERMISSIONS deny-list introduced by PR #1241.
Every kiosk-side request tripped the deny-list before the API key's
scope set (Read / Print Queue / Control / Legacy) was even consulted.
Same root cause as the four QuickMenu System buttons fixed in 0.2.4b3
(Restart Daemon / Restart Browser / Reboot / Shutdown). Missed /update
in that audit on the reasoning "replaces the daemon binary, different
threat surface" — but that's wrong: restart_daemon already replaces
the running daemon process, so daemon-replacement is not a step up in
blast radius. The SSH update is also strictly scoped to the one device
the operator physically controls (git fetch + pip install + systemctl
restart on that host) — same threat profile as the system commands
already running on INVENTORY_UPDATE.
Lower /spoolbuddy/devices/{id}/update from SETTINGS_UPDATE to
INVENTORY_UPDATE so it aligns with the rest of the kiosk-scoped routes
(calibration/tare, display, cancel-write, system/command,
system/command-result, update-status). The main Bambuddy in-app updater
at POST /api/v1/updates/apply keeps SETTINGS_UPDATE — that one runs on
the Bambuddy host and is correctly fenced behind the deny-list.
Reported by @1000Delta. The printer file download (and three sibling
endpoints) raised UnicodeEncodeError: 'latin-1' codec can't encode
characters... on any filename outside U+0000..U+00FF (Chinese,
Japanese, Arabic, accented Latin), because the route pushed `filename`
straight into Content-Disposition: attachment; filename="...".
Starlette/uvicorn encodes response headers as latin-1, so the assignment
crashed at write-time.
New backend/app/utils/http.py::build_content_disposition emits both an
ASCII-stripped legacy filename="..." fallback and an RFC 5987
filename*=UTF-8''<percent-encoded> parameter. Every modern browser
prefers the *= form, so the original Unicode filename round-trips
through Save-As intact.
Same shape was latent in three siblings and fixed in the same PR
(no deferred follow-ups): archive QR endpoint (archive.print_name
from 3MF metadata), project ZIP export (project.name — the existing
isalnum() sanitiser passes non-ASCII through), and the PDF label
streamer (latent today, callers ASCII-only but the helper hardens it).
feat(spoolman-inventory): squashed feature work for rebase onto dev
Squashed all commits from feature/spoolman-inventory-ui onto a single commit
to enable a clean rebase onto dev. Original per-commit history preserved at
backup tag backup/spoolman-inventory-ui-prerebase-20260507-105721.
Slicer "Send to printer" worked on 0.2.3.2 with a queue-mode VP and
started failing on 0.2.4b3 with BambuStudio's generic "storage needs
to be inserted before send to printer" error. Multiple users
reported it across P1S, P2S, Docker bridge, macvlan, and host
networking. @rtadams89's debug-level support archive showed the
smoking gun: slicer establishes MQTT TLS, gets pushall +
get_version, then never opens an FTP connection — pre-flight
rejects before any data transfer.
The 0.2.3.2 synthetic stub baked in three SD/storage indicators
that BambuStudio's "Send" pre-flight reads: home_flag with bit 8
(HAS_SDCARD_NORMAL, 0x100), sdcard=True, and a storage:{free,total}
block. The 0.2.4b3 cached-as-base slicer-mirror (7dea33d0) passes
the live target's push_status through with only an IP rewrite — if
the real firmware doesn't report those fields (P1S/A1 with no SD
card, older field shapes, confirmed on P1S firmware 01.10.00.00),
the slicer sees "no storage" and aborts. H2D and X1C reproductions
worked because those firmwares do report the indicators.
In _send_status_report's cached-as-base branch, after copying the
cache and applying the existing protocol/upload-state overrides:
- home_flag |= 0x100 (preserves any other bits the real printer set)
- sdcard = True (force-set even when real says False)
- storage = setdefault(...) (only fills in if missing — real values
pass through unchanged when the printer reports them)
For VP usage the slicer uploads via FTPS to Bambuddy's filesystem
at /app/data/virtual_printer/uploads/<vpid>/; the printer's actual
SD card is irrelevant on that path, so forcing "storage available"
is correct for the queue / immediate / review modes the
cached-as-base path covers.
chore(i18n): extend parity gate to all locales with strict/info tiers
Previously the script only inspected en/zh-CN/zh-TW, leaving de/fr/it/ja/pt-BR
drift invisible. Now locales are auto-discovered from src/i18n/locales/, and a
STRICT list (de, zh-CN, zh-TW — currently in parity) gates CI while the rest
report informationally until their drift is caught up. ja notably has 27 real
placeholder bugs worth fixing before promotion to strict.
Subsequent backups against Gitea 1.24+ failed with the opaque
"Backup failed: 'tree'" message after the initial-backup fix landed in
7ee89b56. Root cause: Gitea's GET /repos/{owner}/{repo}/git/commits/{sha}
returns the wrapped Commit schema where the tree lives at
data["commit"]["tree"]["sha"], whereas GitHub's same-named Git Database
endpoint returns the unwrapped GitCommit schema with tree at the top
level. The bare commit_response.json()["tree"]["sha"] lookup at
gitea.py:109 raised KeyError: 'tree' and the broad except in push_files
surfaced it as the opaque "Backup failed: 'tree'" string — masking the
real shape mismatch.
Adds a _commit_tree_sha() helper that tries the flat shape first
(GitHub-compatible / older Gitea) and falls back to the wrapped shape
(Gitea 1.24+, Forgejo). Returns None on truly malformed responses;
push_files maps that to a clear "Failed to extract tree SHA from commit
response" instead of leaking a KeyError repr. Keeps the existing-files
diff working on both shapes so subsequent backups don't re-upload every
blob — preferred over the .get()-and-skip approach which would have
required also dropping base_tree from the tree POST and re-uploading
unchanged files on every backup.
feat(spoolman-inventory): squashed feature work for rebase onto dev
Squashed all commits from feature/spoolman-inventory-ui onto a single commit
to enable a clean rebase onto dev. Original per-commit history preserved at
backup tag backup/spoolman-inventory-ui-prerebase-20260507-105721.
Three Bambu Lab catalog rows share #FFFFFF — Jade White (PLA Basic),
Ivory White (PLA Matte), White (PLA Silk). The catalog lookup in
create_spool_from_tray filtered by manufacturer + hex only with no
ORDER BY, so SQLite returned rows in rowid order and the first-inserted
entry (Jade White) won every RFID-driven spool creation regardless of
the actual material the AMS reported. Inserting an Ivory White PLA
Matte roll always produced a spool named "Jade White".
Same class of bug bites any other shared-hex pair across PLA Basic /
Matte / Silk; the whites were just the most visible.
Fix: add a material filter using tray_sub_brands (the printer-reported
material variant — "PLA Matte" / "PLA Basic" / "PLA Silk"), which
matches the catalog's `material` column directly. Use the raw
tray_sub_brands value (captured before the gradient/dual/tri-color
subtype upgrade) because the catalog stores "PLA Basic" for gradient
rolls too — the upgraded subtype lives on the spool, not the catalog.
Also add ORDER BY id to the query so the fallback path (empty
tray_sub_brands — third-party spools / OpenTag tags) is deterministic
across SQLite + PostgreSQL instead of DB-implementation-defined.
Tests: 4 new in test_spool_tag_matcher.py — Ivory White PLA Matte
resolves to Ivory not Jade (the regression pin), PLA Silk White
resolves to White, Jade White PLA Basic still works with all three
#FFFFFF entries seeded, and the empty-sub_brands fallback stays
deterministic via the new ORDER BY.
Existing spools already mis-named in the database don't auto-correct
on next AMS read — the matcher only fires on new RFID-driven creation.
Affected users need a manual rename in Inventory after upgrading.
Two interacting bugs in the Gitea/Forgejo backend, both inherited from
GitHubBackend because PR #1160 assumed Gitea's Git Data API was fully
GitHub-compatible. It isn't, on two specific points:
1. List-shaped ref response. Gitea/Forgejo's
GET /api/v1/repos/{owner}/{repo}/git/refs/heads/{branch} returns a
GET /api/v1/repos/{owner}/{repo}/git/refs/heads/{branch} returns a
list of matching refs even when only one matches; GitHub returns a
single object. The inherited push paths did
ref_response.json()["object"]["sha"] and crashed with
"list indices must be integers or slices, not str" against any
populated Gitea repo.
2. Empty-repo writes refused. GitHub accepts blob/tree/commit POSTs
against a brand-new empty repo and creates the initial commit
implicitly. Gitea refuses every blob POST with 404 until the repo
has at least one commit, so _create_initial_commit silently failed:
blobs returned 404, tree_items stayed empty, the tree POST then
also 404'd ("Failed to create tree").
Fix lives entirely in GiteaBackend — github.py is untouched so the
proven GitHub path takes zero risk. GiteaBackend now overrides
push_files, _create_branch_and_push, and _create_initial_commit:
- _ref_sha() helper accepts both list and dict shapes; called at the
two SHA extraction sites in push_files and _create_branch_and_push.
- _create_initial_commit posts to Gitea's Contents API
(POST /api/v1/repos/{owner}/{repo}/contents with a files array plus
branch + new_branch) which seeds the initial commit + branch in
one transaction and is documented to work on empty repos.
ForgejoBackend extends GiteaBackend with no overrides and inherits
both fixes; tests pin that.
When one spool ran out and the AMS transparently switched to a sibling
slot of the same material, the usage tracker credited the originally-
mapped spool with the full 3MF estimate AND added the fallback spool's
remain%-delta on top — so a 78g print could record as 138g across two
spools, leaving the empty spool's recorded weight beyond its label.
Two interacting bugs:
1. bambu_mqtt.py: the tray-change recorder gated on
`state in ("RUNNING", "PAUSE")`, but P2S firmware briefly transitions
out of RUNNING during the AMS swap (into LOADING etc.), so the
literal-string gate missed the switch entirely and tray_change_log
stayed empty. Re-key on the print-lifecycle flags
(_was_running and not _completion_triggered) so any tray change
between print start and completion is captured regardless of the
momentary gcode_state.
2. usage_tracker.py: the splitting branch was gated on
`not slot_to_tray`, so the splitting code only ran for prints where
the slicer mapping hadn't been captured — i.e. never on the actual
fallback case (slot_to_tray is populated by every print_cmd). Drop
the gate: when tray_change_log has > 1 entries, splitting takes
over and per-segment per-layer gcode usage replaces the stale
mapping. Path 2 (AMS remain%-delta) then naturally skips both trays
because they're already in handled_trays after splitting,
eliminating the double-credit.
When SliceRequest.bundle is set, the dispatch picks the per-category
JSON triplet from a sidecar-stored .bbscfg by name instead of
resolving cloud/local/standard PresetRefs. Mirrors the bundle-aware
preview slice (committed earlier) so live slices match the same
profile triplet the modal previewed against.
Schema:
- SliceBundleSpec: bundle_id + printer_name + process_name +
filament_names (min-length-1 list, plate-slot order)
- SliceRequest.bundle: optional, validator skips preset-required
check when set so bundle-only requests validate
Dispatch:
- _run_slicer_with_fallback branches on request.bundle
- Skips resolve_preset_ref, calls slice_with_bundle
- 3MF + bundle CLI 5xx still falls back to embedded-settings slice
(used_embedded_settings=True surfaces in the response)
- Sidecar 404 (unknown bundle / preset name) maps to 400
The SliceModal's preview slice runs against unsliced project files to
discover per-plate AMS slot consumption. Until now it always used
slice_without_profiles — accurate slot mapping (a model property) but
gram numbers were derived from the file's embedded process settings,
which can drift from the triplet the real print will use.
When the caller provides a bundle id + printer/process/filament preset
names, get_preview_filaments now routes through slice_with_bundle so
the preview's gram numbers match what the real print will produce.
Cache key picks up a bundle-context fingerprint so different bundle
picks on the same file occupy distinct entries.
Backend:
- slice_preview.get_preview_filaments: optional bundle_* params
- library.py + archives.py: forward params via /filament-requirements
Frontend (forward-compat for the upcoming SliceModal Bundle tier):
- api.getLibraryFileFilamentRequirements / getArchiveFilamentRequirements
accept an optional 4th-arg bundle context object
Wires Bambuddy to the orca-slicer-api fork's bundle endpoints (shipped
in bambuddy/bundle-import). Users will eventually upload a BambuStudio
"Printer Preset Bundle" (.bbscfg) once per printer; subsequent slices
pick from the bundle by preset name instead of re-uploading the JSON
triplet every time.
Service layer:
- BundleSummary / BundleNotFoundError types
- import_bundle / list_bundles / get_bundle / delete_bundle methods
- slice_with_bundle: POST /slice with bundle id + per-category names
instead of attached profile JSONs
Routes (LIBRARY_UPLOAD perm gate):
- POST /api/v1/slicer/bundles
- GET /api/v1/slicer/bundles
- GET /api/v1/slicer/bundles/:id
- DELETE /api/v1/slicer/bundles/:id
All routes proxy via _resolve_slicer_api_url so they follow the user's
preferred_slicer setting (bambu_studio vs orcaslicer). Status-code
mapping treats sidecar 4xx as 400, BundleNotFoundError as 404,
unreachable as 503, and sidecar 5xx as 502.
Restoring a settings backup ZIP appeared to succeed but the user found
settings reverted to defaults, most printers/archive rows missing, and
~1 GB of archive files on disk with only 1 row in the database. Same
shape as #668 (closed in March without an actual fix — that user
happened to make it work by rolling back to a stable release, which
masked the bug).
Cause: the live DB runs in WAL mode. Anything the fresh container wrote
between startup and the restore call (seed_default_groups, init_db
migrations, heartbeat writes) sits in bambuddy.db-wal with valid
checksums, and engine.dispose() doesn't checkpoint it. FastAPI's
dependency injection keeps the route handler's own `db: Depends(get_db)`
session checked out across engine.dispose() (per SQLAlchemy docs,
dispose only closes pooled connections, not checked-out ones), so the
WAL inode is held open through the whole restore. After shutil.copy2
rewrote the main DB inode in place, SQLite's WAL recovery on the next
init_db() re-applied the stale frames on top of the restored content,
partially clobbering it with fresh-install state.
Initial fix attempt of deleting -wal/-shm/-journal sidecars before the
copy was insufficient (verified experimentally) — the still-open
request session reads the unlinked sidecars via held fds and bleeds
the WAL state back into the new file when it eventually closes.
Real fix: replace shutil.copy2 with SQLite's online backup API
(src_conn.backup(dst_conn)). The page-by-page protocol opens both DBs
as proper SQLite connections, acquires the right locks, and routes
new pages through the destination's own WAL. Concurrent open sessions
see their own transactional snapshot until they close (transaction
isolation) but can't corrupt the restored state.
Closes the longest-standing inventory gap — finding a specific spool
in a closet of 50 partials. Per-spool icon button on every inventory
card and table row, plus a "Print labels..." header action that opens
a multi-select picker pre-loaded with the currently filtered spools.
Four pre-built templates: AMS holder (30 x 15 mm) for the popular
Makerworld AMS Filament Label Holder, single box label (62 x 29 mm)
for Brother PT/QL or Dymo small labels, Avery L7160 (A4, 21 per
sheet), and Avery 5160 (US Letter, 30 per sheet). Each label carries
the colour swatch (with multi-colour gradient stripes for spools
with extra_colors set), brand, material, name, the *spool ID*
(bsaunder's articulated user-need: telling 8 spools of "PLA White"
apart, especially partials), and a QR code that deep-links to
/inventory?spool=<id> for phone-scan round-trips. Box-label adds
storage location; AMS-holder drops the QR — at 30 x 15 mm there is
no room for swatch + text + QR without truncating away the spool ID,
and AMS-bay identification is at arm's length where the swatch and
ID are enough.
Server-side rendering via ReportLab + qrcode (already a dep). Pure
Python, no headless browser, no system libs. Output is byte-identical
across browsers, Avery sheets align to <0.1 mm, and bulk export is
one click for one PDF. Two endpoints — POST /inventory/labels (local
DB) and POST /spoolman/labels (Spoolman-backed) — gated on
INVENTORY_READ, capped at 500 spools per request, returning
application/pdf via StreamingResponse. The renderer is decoupled
from the SQLAlchemy model via a LabelData dataclass so the same code
path serves both modes.
Modal picker scales to large libraries: search (substring match
across name / brand / #ID), material filter chips derived from the
visible spools, additive Select-all-visible / Deselect-visible /
Clear-all actions so selections survive filter changes. Restyled
twice in development — first cut used generic Tailwind which clashed
with the inventory's bambu-dark palette; second cut switched to
bambu-dark-secondary / bambu-green / bambu-gray to match.
Two render bugs found during visual inspection of generated PDFs and
fixed before commit:
1. AMS-30x15 template originally produced labels with only swatch
+ QR and no text at all — the side-by-side layout left <5 mm
for the text column, so the renderer bailed without drawing
anything. Layout split into tight (h<20mm) and roomy (h>=20mm)
regimes; tight regime drops the QR and gives the right column
to brand + material + a 13pt-bold spool ID.
2. Box-62x29 template aggressively truncated text — swatch + QR
each at ~14 mm on a 26mm-tall label squeezed the text column
to ~16 mm, turning "Polymaker Ivory" into "Polymak..." and
"Polymaker . PLA . Matte" into "Polymaker ...". Swatch capped
at 16 mm, QR capped at 18 mm and constrained to ~20% of width,
leaving the text column ~30 mm — full names render without
truncation.
Both bugs pinned by regression tests in test_label_renderer.py that
render with pageCompression=0 so the resulting PDF bytes contain the
text as ASCII and `assert b"Polymaker" in pdf` works.
Daily builds since 889c8bd8 (Apr 29) silently destroyed archive copies
and library file bytes on every print completion. Reprint / View G-code
later returned 404 with no log line explaining why; the DB row was
intact and the archive grid kept showing the entry, but the file
behind archive.file_path no longer existed on disk.
Root cause: #1166 added three dispatch sites that cache the live
archive copy (and library file bytes for Direct-Print) in the shared
3MF download cache, so /cover could skip a redundant FTP transfer
mid-print. The cache was originally designed for transient downloads
under archive_dir/temp/, and clear_3mf_cache(printer_id) — called
from on_print_complete to keep that temp dir from accumulating —
happily unlink()'d every cached path. Path.exists() guarded the
unlink, so no exception, no warning, just silent destruction. Listing
didn't change; only acting on the archive surfaced the 404.
Fix: clear_3mf_cache._maybe_unlink refuses to unlink any path outside
archive_dir/temp. Cache dict is still cleared (so re-cache continues
to work and /cover hits a fresh path next print), only the on-disk
delete is gated. Persistent locations — archive/<printer_id>/...,
archive/unassigned/... (VP-archived prints with printer_id=None),
library_files/..., is_external library mounts — all survive.
Regression test test_clear_does_not_delete_persistent_files pins the
contract end-to-end: archive 3mf, library 3mf, and temp 3mf all
cached for the same printer; after clear, all three cache entries
are dropped from the dict, but only the temp file is unlinked from
disk. Two existing tests updated to put fixtures under
archive_dir/temp.
MakerWorld 3MFs sliced for P2S (and likely other Bambu printers) ship
project_settings.config entries with "-1" on fields BambuStudio writes
to mean "inherit from the parent process preset". The headless slicer
CLI's StaticPrintConfig validator runs against the embedded settings
*before* --load-settings overrides apply, so the sentinel trips the
field's lower-bound check and the CLI exits non-zero before the supplied
profile triplet is consulted. Both slice paths (with-profiles and the
embedded-settings fallback) read the same config and fail the same way,
so the user surfaces the error.
Surgical fix: open Metadata/project_settings.config, remove allowlisted
keys when their value is exactly "-1", re-zip. Allowlist starts with the
two from this report (raft_first_layer_expansion, tree_support_wall_count)
plus prime_tower_brim_width (a known sentinel cited in earlier reports).
Non-allowlisted "-1" values are left alone so a blanket strip can't
corrupt legitimate negative values. Other zip entries pass through
byte-identical — no risk of the failure mode the previous full-strip
experiment hit (silent CLI exit on initialisation).
Sanitiser runs before both slice_with_profiles and slice_without_profiles
paths since both fail on the same sentinel.
13 new unit tests in test_project_settings_sentinel_sanitiser.py cover
the allowlist removal contract (parametrised across all sentinel keys),
preservation of unaffected values, byte-identical round-trip of unrelated
zip entries, and defensive fallbacks for non-zip / malformed / no-config
inputs.
Adding new sentinel keys is one-line: append to
_PROJECT_SETTINGS_SENTINEL_KEYS in library.py.
Two consecutive plates of the same model would create the second print's
archive with the first plate's metadata: subtask_name lags across the
boundary while gcode_file is fresh, so the FTP candidate list (built
from subtask_name first) lands on the previous plate's still-resident
upload. The 3MF parser then locks the wrong _plate_index, name, time
estimate, and per-slot filament data into the archive at creation.
Fix peeks the downloaded 3MF's slice_info plate index, compares against
parse_plate_id(filename) (the plate parsed from /Metadata/plate_N.gcode,
which always reflects what's running), and on mismatch retries FTP with
swap_plate_suffix(subtask_name, expected_plate) — handling both the
spaced "Plate N" and underscored "_plate_N" suffix forms seen in real
subtask_names. If the retry finds a matching 3MF, the wrong file is
dropped and the corrected one feeds the archive; if no match is found
(or no swap is possible) the wrong file is dropped and the existing
no-3MF fallback creates an archive whose name reflects the right plate.
The validation only runs when parse_plate_id() returns a value, so
single-plate / cloud-named / non-Bambu jobs are unaffected.
17 new unit tests in test_archive_plate_validation.py cover both helpers:
plate-index peek across malformed / missing / non-integer / non-zip
inputs, and the suffix swap across both casings, the underscored form,
case-insensitive matching, and rejection of names without a recognised
suffix.
The Tailscale toggle was supposed to obtain a publicly-trusted Let's Encrypt
cert via `tailscale cert` so users wouldn't need to import Bambuddy's CA into
the slicer. End-to-end testing showed this was always going to fail:
- Bambu Studio and OrcaSlicer refuse hostname input in the Add Printer
dialog (IP-only).
- Their printer-MQTT trust path validates only against the bundled BBL CA
store (`printer.cer`), NOT the system trust store. Confirmed against
ClusterM/open-bambu-networking's clean-room reimplementation:
`mosquitto_tls_set(BBL_CA)` + `verify_peer=1` + `tls_insecure=true` —
chain validation against BBL CA only, hostname check intentionally
skipped (because Bambu's printer cert CN is the device serial).
- LE certs don't chain to BBL CA, so the slicer rejects with the
well-known "-1" before any hostname/IP logic runs.
The cert-import step is unavoidable; LE provisioning was dead code for slicer
connections. Pivot:
- Toggle stays as an informational marker — when ON, the VP card surfaces
the host's Tailscale IP + MagicDNS hostname so users know what to paste
into the slicer.
- Cert is always self-signed (signed by `bbl_ca`).
- Tailscale exposure is via the existing bind_ip dropdown, which already
includes `tailscale0` IPs.
- Tailscale's role is strictly network reach — same trust burden as LAN.
Backend cuts:
- `tailscale.py`: `provision_cert`, `ensure_cert`, `cert_needs_renewal`,
`_FQDN_RE`, `_HTTPS_DISABLED_RE`, `TS_CERT_EXPIRY_THRESHOLD_DAYS`,
`cryptography` import. Keep `get_status` and `TailscaleStatus`.
- `certificate.py`: `ts_cert_path`, `ts_key_path`, `use_tailscale_cert`.
- `manager.py`: `tailscale_fqdn` field, `_cert_renewal_task`,
`_cert_restart_task`, `_cert_renewal_loop`, `_restart_for_cert_renewal`,
`_cancel_renewal_task`, `_cancel_restart_task`. Simplify
`_resolve_cert_and_advertise` to a sync method that just generates the
self-signed cert. Drop `tailscale_disabled` from the change-detection
diff (toggle is informational — no service restart needed).
- `routes/virtual_printers.py` + `routes/settings.py`: drop the
`tailscale_not_available` 409 guard on toggle-enable.
Frontend cuts:
- `VirtualPrinterCard.tsx`: FQDN/IP display sourced from
`multiVirtualPrinterApi.getTailscaleStatus()` (host-level) when toggle
is ON, instead of `printer.status.tailscale_fqdn` (cert side-effect,
no longer populated). Drop the `tailscale_not_available` toast handler.
- `api/client.ts`: drop `tailscale_fqdn` from the VP status type.
- i18n: rewrite `tailscaleDisabled.description` in all 8 locales to drop
the "no cert import" promise. Remove `toast.tailscaleNotAvailable` key.
Docs:
- Wiki `features/virtual-printer.md`: rewrite the entire Tailscale section
— remove the LE-cert + HTTPS-Certs-toggle + tailscale-cert-operator
steps, document the toggle as informational, keep the Docker socket
mount + LXC TUN troubleshooting (those still apply for daemon
reachability).
- README: drop "the Tailscale benefit here is the tunnel, not cert-import
elimination" framing in favour of "surfaces the IP for paste into
slicer; CA import unchanged because BBL CA store, not system trust
store, is what gets validated".
Tests:
- `test_tailscale.py`: reduced to surviving `get_status` cases (binary
missing, command fails, success, empty DNSName, malformed JSON).
- `test_virtual_printer.py::test_sync_from_db_restarts_on_tailscale_disabled_change`
→ `test_sync_from_db_does_not_restart_on_tailscale_toggle` (toggle is
informational; `remove_instance` must NOT be called).
- `test_virtual_printer_api.py::TestVirtualPrinterTailscaleGuardAPI` →
`TestVirtualPrinterTailscaleToggleAPI` (single test asserts both
directions succeed and daemon is never consulted).
- `VirtualPrinterCard.test.tsx`: mock now stubs `getTailscaleStatus`;
FQDN-copy block drives data through that query.
DB column `tailscale_disabled` is kept (persists toggle state) — Postgres-
safe column drop is harder; future cleanup can remove if the toggle goes
away entirely. LE cert files on disk (`virtual_printer_ts.{crt,key}`) are
left in place per VP — harmless residue, manual cleanup if desired.
Verified: ruff clean, 2484 backend unit tests pass, 17 frontend VP-card
tests pass, frontend build succeeds, live service restart confirms VPs
serve `issuer=CN=Virtual Printer CA` on the Tailscale interface — slicer
trusts the user-imported bambuddy CA and skips hostname checks, so MQTT
connection succeeds end-to-end.
In non-proxy VP modes (Immediate / Review / Print Queue), the slicer now
sees real AMS / FTS / nozzle / k-profile state from the target printer
and streams the live camera — full slicer-as-remote functionality without
giving up Bambuddy's queue / archive / dispatch features.
Architecture (cached-as-base, single source of truth). The bridge caches
the latest real push_status and info.get_version response from Bambuddy's
existing per-printer MQTT subscription — no second session on the printer,
firmware in-flight budget unaffected (#1164). _send_status_report serves
a near-byte-identical copy of the cached push with only the upload-state-
machine fields overridden. Command responses (extrusion_cali_get, AMS
write acks, xcam) fan out raw — they carry sequence_ids the slicer is
waiting on. Slicer-issued commands forward to the printer except
project_file / gcode_file, which still terminate locally because the file
lives on Bambuddy. Camera is a raw TCPProxy on bind_ip:322 → printer:322,
same approach proxy mode uses.
Field-shape gotchas pinned in the bridge module's docstring and the
new test file:
- Real Bambu pushes use json.dumps(indent=4) wire format. Compact JSON
fails BambuStudio's Send pre-flight silently.
- net.info[*].ip is the FTP destination IP (little-endian uint32).
Without rewriting to the VP bind IP, the slicer FTPs straight to
the real printer.
- upgrade_state.sn rewritten to VP serial; AMS-hardware sn fields
(n3f/0.sn etc.) left alone.
- ipcam.rtsp_url passes through unchanged; BambuStudio overrides the
URL host with the device IP it bound on, so :322 lands on the VP's
TCPProxy.
- extrusion_cali_get must forward; answering it locally hides the
user's stored per-filament k-profiles.
Setup nuance for camera: the VP's access code must match the target
printer's because the slicer authenticates RTSPS with whatever access
code is in its profile. MQTT and FTP work either way.
Tested e2e with BambuStudio and OrcaSlicer against H2D (dual-nozzle,
AMS 2 Pro + AMS HT) and X1C across all three non-proxy modes — sync,
send, k-profile lookup, AMS configuration from slicer, and live camera
all work. Proxy mode is untouched: SlicerProxyManager owns its own
proxies and never instantiates SimpleMQTTServer or MQTTBridge.
25 new tests in backend/tests/unit/test_vp_mqtt_bridge.py cover lifecycle,
caching, identity / IP rewriting, wire format, slicer→printer routing,
and the LE-uint32 IP encoder against the real H2D capture value.
Pre-fix, _background_notifications in main.py:3434 built archive_data
with print_time_seconds (the slicer's pre-print estimate parsed from
the 3MF at archive creation), and notification_service.py:909 formatted
that field straight into the {{duration}} template variable. A print
cancelled 2 minutes into a 3-hour estimate notified "duration: 3h".
Compute actual_time_seconds from started_at/completed_at in main.py and
add it to archive_data. notification_service.py prefers it, falls back
to print_time_seconds when the actual can't be derived.
Also add "cancelled" to the list of statuses that get completed_at set
in update_archive_status — pre-fix only completed/failed/aborted got a
timestamp, so queue-UI cancellations had no actual elapsed to compute
from. Audited every completed_at consumer; none depend on NULL to mean
"cancelled" (status field already carries that signal), and the
statistics-totals aggregation gets more accurate too as a side effect.
3 new regression tests in TestNotificationVariableFallbacks pin the
{{duration}} variable contract (actual wins over estimate; estimate
falls in when actual is missing; "Unknown" when both absent).
go2rtc and several IP cameras still emit a warm-up / black frame on every
fresh MJPEG connection — even with the v0.2.4b2 warm-up-skip fix it
slipped through intermittently for @nkm8's setup. His own bisect named
the clean solution: go2rtc exposes /api/frame.jpeg as a dedicated
single-frame endpoint that never returns the encoder's stale keyframe.
Adds an optional external_camera_snapshot_url column on printers. When
set, every single-frame capture path (snapshot endpoint, [SNAPSHOT]
notification thumbnails, [PHOTO-BG] finish photo, layer timelapse,
Obico ML, plate-detect / calibrate-plate) routes through _capture_snapshot
on the override URL via plain HTTP GET, bypassing the warm-up dance.
Live view stays on the configured stream URL — only single-frame
captures use the override. Override is camera-type-agnostic. SSRF guard
applies (existing _sanitize_camera_url allowlist). Empty string treated
as unset.
Settings UI: new "Snapshot URL (optional)" input + Test button under
External Cameras, hidden for camera_type=snapshot since the live URL is
already a single-frame source. en + de fully translated; 6 other locales
seeded with English copy.
5 backend tests pin the routing contract; 3 frontend tests pin the
input + debounced PATCH. Documented in
bambuddy-wiki/docs/features/camera.md with the go2rtc example.
