ghcr.io pull baseline (~10k/day rising → ~8-12k active installs) puts
sponsor conversion at 0.08% — roughly an order of magnitude under
industry-benchmark for OSS with visible CTA. The Settings banner from
0d4b9d4e gives passive every-visit visibility on one page; this adds
opt-out-able active visibility at moments where the user has just
earned something with Bambuddy.
Five trigger families with a 14-day cross-family cooldown: prints
(100/500/1000/2500/5000), cost (100/500/1000 tracked filament +
energy), archives (50/250/1000), anniversary (1 year), version-update
(re-armable on each major bump). New sponsor_toast_state table with
nullable user_id so auth-disabled installs get the same trigger logic
through one code path (NULL-keyed install-default row).
New PrinterSensorHistory table + 60s recorder + GET/DELETE /printer-sensor-history
route gated behind a new PRINTER_SENSOR_HISTORY_READ scope (separate from AMS). UI
adds a 10x10 LineChart icon on each heater tile - click body opens the existing
target-temp popover unchanged, click icon opens a HeaterHistoryModal mirroring the
AMSHistoryModal shape (kind toggle + 6h/24h/48h/7d range + current/avg/min/max +
recharts line for value + dashed target). Read-only X1C/P2S chamber tile finally
gets an interaction. Retention configurable via printer_sensor_history_retention_days
(default 30, sibling of ams_history_retention_days). 8 new i18n keys translated in
all 11 locales, parity green. 4 backend + 6 frontend tests added; full pytest -n 30
6226/6226, vitest 2176/2176, ruff/eslint/build all clean.
Two tightly-coupled deliverables in one drop -- a new AMS Filament Backup
status/control surface, and the #1766 fix that depends on it.
Added -- AMS Filament Backup status + control
- Parse bit 18 of top-level print.cfg into PrinterState.ams_filament_backup
on every push_status. Verified against OrcaSlicer source
(DeviceManager.cpp:4961) and a live H2D ON/OFF capture. Tri-state
(None = A1 family / pre-cfg push) preserves today's behaviour.
- Hold-timer guard (3 s) prevents stale frames from flickering the badge
back to the printer's old cfg after a user-initiated toggle.
- POST /printers/{id}/ams-backup toggle, set_ams_filament_backup() client
method calling _set_print_option("auto_switch_filament", enabled).
- GET /printers/{id}/inventory-remain endpoint exposes the same map the
dispatcher uses (internal and Spoolman modes both work uniformly).
- Small icon badge in the printer card's "Filaments" section header
(placement reads as printer-wide because the cfg bit is printer-wide,
not per-AMS). Click to toggle, success toast.
- 5 i18n keys x 11 locales for the badge UI.
Fixed -- #1766: prefer_lowest didn't pick lowest, ignored backup state
- Backend gate in _compute_ams_mapping_for_printer: coerce prefer_lowest
to False when status.ams_filament_backup is False; log the skip.
- New effectivePreferLowest(setting, backup) helper applied at every
frontend sort entry point: single-printer PrintModal, multi-printer
hook per-printer, PrinterSelector InlineMappingEditor, FilamentMapping
standalone editor (the last had NO preferLowest awareness at all
before this change).
- New preferLowestSortKey(f, inventoryByTrayId) mirrors backend's two-tier
key exactly, including the banding tie-break (regular AMS < AMS-HT <
external) so the client-side pre-compute matches the dispatch-time pick.
An earlier draft used a flat `amsId * 4 + trayId` priority which gave
external slots (ams_id = -1) a NEGATIVE priority -- caught in code
review before commit.
- Settings -> Filament -> "Prefer lowest remaining filament" gets an
explanatory note about the printer-side AMS Backup dependency, with
i18n key in all 11 locales.
The 3MF parser sums prediction + weight across every plate (#1593) so the
archive card can headline the whole project — correct for the card, wrong
for the completion notification of a single plate. The queue UI already
re-reads the 3MF per-plate at print_queue.py:272-285; mirror that for the
notification path so Discord / Pushover / email show the plate's actual
duration and grams instead of the project sum. Helper fails open on every
error path so a missing or corrupt 3MF can't block the notification.
BambuStudio's project_file MQTT command for O1C2 (the H2C dual-
nozzle-rack variant) carries nozzle_mapping (per-filament physical
nozzle position IDs) and nozzles_info (per-extruder rack metadata).
The VP intake was dropping both, so the H2C firmware fell back to
"last matching nozzle type" auto-pick and ignored the user's
slicer choice — every HF print landed on R2, every standard print
landed on R4.
Carry both fields through the VP intake → queue item → MQTT
dispatch path. New nullable TEXT columns on print_queue, non-
branched ALTER (matches ams_mapping / filament_overrides
precedent). Dual-nozzle gate at start_print() keeps the fields
off single-nozzle dispatches. Fail-open on malformed JSON —
firmware auto-picks, never worse than pre-fix.
Stamps both fields on every plate in the multi-plate Send All
loop (#1697 / #1188 precedent).
ams_mapping2 still handles H2D/X2D dual-extruder routing
unchanged; this fix is scoped to the O1C2 rack-swap mechanism.
The makerworld /status, /resolve, and /import handlers passed
current_user directly into get_stored_token / _build_service.
require_permission_if_auth_enabled returns None for API-keyed
callers by design (core/auth.py:1414), so the lookup always
missed even when the key's owner had a stored Bambu Cloud session.
Result: a "requires a Bambu Cloud login" 400 on every API-keyed
import, regardless of the owning account's actual cloud state.
Wire resolve_api_key_cloud_owner (already used by the slice path
in #1182 — slicer_presets.py:491 and library.py:3871) into the
three makerworld routes that read the cloud token. The handler
falls back to the API-key owner via cloud_token_user =
current_user or api_key_cloud_owner, then passes that through.
import_instance also propagates the resolved user to the
owner_id arg on save_3mf_bytes_to_library, so the resulting
LibraryFile.created_by_id reflects the key's owner instead of
NULL.
Fail-closed semantics preserved: resolve_api_key_cloud_owner
already fences on api_key.can_access_cloud, so keys with only
the per-route scope (can_read_status / can_manage_library) still
take the existing "requires Bambu Cloud login" path — no auth
widening.
/recent-imports is unchanged — it only uses current_user as a
permission gate (_ = current_user) and never touches the cloud
token.
Bambuddy's archive cards were blank for every print sliced through the
BS or Orca docker sidecars. The "Some recent prints couldn't be archived
with thumbnails" banner pointed at install step 4 which is unrelated —
that flag only fires on FTP-fetch failures, not on missing-thumb in the
sliced 3MF.
Root cause is upstream of Bambuddy: neither slicer CLI renders
Metadata/plate_N.png when invoked headlessly with --slice --export-3mf.
That render is a separate code path triggered by --export-png, which is
mutually exclusive with --export-3mf and additionally needs a working
display backend (BS 02.07.x's bundled GLFW is hard-locked to Wayland —
even XDG_SESSION_TYPE=x11 + GDK_BACKEND=x11 + QT_QPA_PLATFORM=xcb don't
switch it back). An Xvfb display in the sidecar wouldn't help even if we
wired the second-pass call. The Orca sidecar has been silently shipping
thumbnail-less 3MFs from STL inputs since launch; nobody noticed.
Fill the gap on the Bambuddy side: new plate_thumbnail.py renders the
missing thumbnails after the slice returns. inject_plate_thumbnails_if_missing
parses the sliced zip, finds every Metadata/plate_N.gcode entry that
doesn't have a matching plate_N.png, loads 3D/3dmodel.model via trimesh,
renders an isometric Bambu-green-on-dark view at 512x512 + 128x128 via
the same matplotlib Agg pipeline as stl_thumbnail.py, and re-packs the
zip with the PNGs injected. Visual style matches Bambuddy's existing
library thumbnails — archive cards stay consistent inside Bambuddy rather
than chasing parity with desktop Studio's plate render. Best-effort:
input bytes are returned unchanged on any failure so the slice flow itself
can never fail because of a missing thumbnail. Idempotent: re-running on
an already-injected 3MF returns the input verbatim.
Wired into both library.py slice paths via result._replace; covers the
cross-class merged-multi-plate path automatically (merged bytes flow into
the same write site). No sidecar Dockerfile change required — an earlier
attempt to install Xvfb in Dockerfile.bambu-studio was a false start and
is not part of this drop.
Dependencies: trimesh's 3MF loader uses networkx (scene-graph traversal)
and lxml (model.xml parse) lazily inside the 3MF code path — both added
to requirements.txt because they aren't strict trimesh transitives.
GET /api/v1/printers/ and /api/v1/printers/{id} return access_code
only when the caller holds PRINTERS_UPDATE. Adds PrinterResponseWithSecret
as the elevated response shape; PrinterResponse no longer carries the
field. Auth-disabled single-trust mode preserved.
The 24h session cap from the M-2 audit finding was hard-coded, so the
"Remember Me" checkbox could only control storage location, never
duration. Add session_max_hours setting (default 24, max 720) honoured
at all four token-issuance sites: plain login, 2FA TOTP/email, 2FA
backup, OIDC.
- backend/app/core/auth.py: SESSION_MAX_HOURS_HARD_CEILING + resolver
that clamps to [1h, 720h] and falls back to 24h on missing/blank/
unparseable. DB errors propagate — the login transaction must abort
on a broken DB rather than silently extend or shrink the lifetime.
- backend/app/api/routes/auth.py, mfa.py: all four sites read the
resolved value instead of ACCESS_TOKEN_EXPIRE_MINUTES directly.
- backend/app/schemas/settings.py, routes/settings.py: schema field
with ge=1 le=720 + int coercion in _build_settings_response.
- frontend/src/pages/SettingsPage.tsx: half-width card at top of
Settings -> Users left column with 24h/7d/30d presets, custom input,
and a yellow warning when value > 24h.
- frontend/src/i18n/locales/*.ts: 8 new keys per locale, real
translations in all 11 (en/de/es/fr/it/ja/ko/pt-BR/tr/zh-CN/zh-TW).
- backend/tests/integration/test_session_policy.py: 15 tests across
resolver clamping, login JWT exp end-to-end, settings API round-trip.
Already-issued tokens keep their original expiry; the new setting only
affects future logins.
Restructures the queue page around three tabs (Queue / History / Timeline)
and adds first-class batch grouping plus a real time-based timeline.
Queue tab
- Layout toggle: Sort by Position (flat list) or Group by Printer (per-
printer section cards with aggregate count / time / weight headers).
- Batch grouping: pending items sharing a batch_id render as a single
collapsible row with aggregate stats; children draggable within the
batch only. Per-batch collapse state in localStorage.
- Multi-drag: dragging any selected row moves all selected items as a
contiguous block via DragOverlay (+N ghost).
- Selection bar gains a Group as batch action when 2+ ungrouped items
are selected. Ungroup lives on the batch parent row.
History tab
- Two-line rich rows: filament color swatch + weight + type, user
attribution, inline error message on failed / skipped rows.
- Responsive 1 / 2 / 3 column grid so a long history uses available
width instead of stretching one row per line.
- Batch siblings group into a collapsible parent with status-rollup
chips (3 OK / 1 failed / etc).
- Thumbnail hover preview shows the full image at 192x192 next to the
small thumb.
Timeline tab
- Replaces the hourly-list view with a Gantt swimlane: one row per
printer (plus per target_model and unassigned), horizontal hour
axis, jobs as bars positioned by start time and sized by duration.
- Live NOW marker.
- Only committed schedules are rendered: currently printing items,
pending items with scheduled_time, and pending ASAP behind an active
print. Staged (manual_start), waiting (waiting_reason), and ASAP
jobs on idle printers are filtered out.
- 24h rolling window with 12h step controls.
- Per-bar tooltip with start, end, progress, batch name.
Backend
- POST /queue/batches creates a batch, optionally assigning existing
pending item_ids (manual grouping) or returning an empty batch the
client can attach to subsequent /queue/ POSTs.
- POST /queue/batches/{id}/ungroup clears batch_id from all members
(skipping items the caller does not own) and deletes the batch row
when no members remain.
- POST /queue/ accepts an optional batch_id and validates that the
batch exists, is active, and the caller may modify it. The existing
quantity > 1 auto-batch path still fires when no batch_id is sent.
PrintModal
- When N plates from one source are queued in a single submission
(model assignment or single printer), the modal pre-creates a batch
and passes its id to each addToQueue call so multi-plate jobs land
grouped automatically. Falls back to ungrouped items if the batch
pre-create fails.
The "0.0.0.0" written into the support bundle is a JSON sentinel that
scrubs the printer's local IP plus the gateway/peers it sees — not a
socket bind address. Annotate inline so bandit stops flagging it.
VP queue-mode multi-plate Send All
==========================================
BambuStudio / OrcaSlicer "Send All" of a multi-plate project uploads ONE
3MF containing every plate (one FTP STOR, single filename) — slice_info.config
inside the file lists N <plate> blocks with their own index metadata and
their own Metadata/plate_N.gcode payload. Pre-#1733 the VP queue path
called _extract_plate_id which returned only the FIRST plate index, and
_add_to_print_queue built exactly one PrintQueueItem from it. Plates 2..N
silently dropped on the floor. From the user's perspective: Send All of a
3-plate project produced 1 queue item, indistinguishable from a regular
single-plate Send, with no log line to explain the discrepancy.
The wire was confirmed against the live H2D-1 Proxy VP: the same file
ships whether the user clicked Send or Send All; the only intent signal
is the count of <plate> blocks inside slice_info.config.
Fix: replaced _extract_plate_id (-> int | None) with _extract_plate_ids
(-> list[int]). The list contains every <plate> block's index in order;
falls back to [1] when slice_info.config is missing / unparseable so the
single-plate case is preserved. _add_to_print_queue now loops over the
list and creates one PrintQueueItem per plate, with:
- plate-specific position = MAX(position) + iteration_number, so the
items inherit consecutive positions and the slicer's plate order
becomes the queue execution order.
- per-plate required_filament_types / filament_overrides via
extract_filament_requirements(file_path, plate_id) — the plate-aware
filter shipped with #1697 — so the scheduler's per-printer "Any X"
matching dispatches each plate onto a printer with the right
colours loaded for THAT plate, not for plate 1's filament set.
- shared archive_id across all plates (one upload = one archive row).
- the VP's auto_dispatch + manual_start posture inherited unchanged.
Net behaviour: single-plate Send hits the loop once → exactly today's
result (one queue item, plate_id from the slicer, one archive). Multi-
plate Send All of a 3-plate file → 3 queue items, plate_id 1/2/3,
consecutive positions, all referencing the same backing archive.
Archive delete cascades to queue rows
=============================================
Previously the soft-delete path (the default the trash-can button uses)
called _cancel_pending_queue_items which only flipped queue rows with
status='pending' to status='cancelled' while leaving every other status
alone AND leaving every row in the DB. The Send All multi-plate work
above made this much more visible: deleting an archive backed by N
queue items now had to clean up N rows, and what users saw instead was
N "cancelled" rows lingering in the queue history.
Backend:
- Replaced _cancel_pending_queue_items with _delete_related_queue_items
(db, archive_id) -> int. DELETEs every queue row where
archive_id = X regardless of status. Matches what the hard-delete
path already did via the ON DELETE CASCADE FK on
print_queue.archive_id — both paths now produce the same end state.
- Print history lives in PrintLogEntry (FK ON DELETE SET NULL) and is
untouched; Quick Stats / accuracy bands are preserved across both
delete paths.
- 409 guard on archives.py::delete_archive when any related queue
item is currently status='printing'. Both soft and hard delete are
gated; deleting the archive while a print is live would strip the
dispatcher's metadata trail (filament / plate / ams_mapping) out
from under the running print.
- New GET /archives/{id}/delete-impact endpoint returns
{related_queue_items: N, currently_printing: M}. Cheap, single
endpoint, deliberately NOT folded into the archive list response
so the much larger list endpoint isn't forced to run the same
query per row.
Frontend:
- ArchivesPage delete-confirm modal queries the new endpoint when the
modal opens (useQuery with enabled: showDeleteConfirm) and renders
an amber "N queue items linked to this archive will also be removed"
line when total > 0 AND printing = 0, OR a red "Cannot delete —
M queue items are currently printing" line when printing > 0
(confirm button disabled in that case so the user can't bonk the
409 on submit).
- ConfirmModal gained an optional confirmDisabled?: boolean prop —
isLoading was the only disable knob before; this adds the external-
precondition path.
- 2 new i18n keys (deleteQueueItemsWarning, deleteBlockedByPrinting)
translated across all 11 locales per feedback_translate_dont_fallback —
no English fallbacks.
No DB migration — the CASCADE FK was already in place; only the helper's
semantics changed.
Two warnings polluting every A1 support bundle on healthy prints, both
unrelated to the timelapse-default behaviour the issue actually reports.
1. mqtt_bridge.py's post-bind nudge calls request_status_update on the
real printer's MQTT client to populate the bridge cache without
waiting for the next periodic pushall. The bind frequently races the
TLS handshake, especially on A1 firmware. Skip the nudge when
state.connected is False — the periodic pushall fills the cache
anyway. The WARNING in bambu_mqtt.py stays for the genuinely-
actionable callers (refresh-status API, bug reporter).
2. Post-finish SD-card cleanup (and the symmetric forced-timelapse dir
walk) used delete_file_async's bool return to drive a WARNING when
all candidates failed. A1 firmware self-cleans the SD card before
our cleanup runs — every candidate FTP-DELE returns 550, we burn
the retry budget, then WARN on a successful print. Introduce
DeleteResult.{DELETED,NOT_FOUND,FAILED} so the helpers only WARN
on real network/auth/transient failures. NOT_FOUND advances to the
next candidate without consuming the 2s backoff. User-facing delete
endpoint returns 404 on NOT_FOUND.
The support bundle shipped support-info.json + bambuddy.log, but the raw
shape of the printer's MQTT push_status — the field that blocks per-model
work like AMS Backup detection (deferred in 85fbd7fc) and every vt_tray /
vir_slot / mapping shape regression — was never captured.
Each connected printer now contributes push-status/printer-{i}.json with
{model, firmware_version, captured_at, raw_data}, indexed against
support-info.json["printers"]. Two-pass redaction: a structural walk
drops user-private keys (subtask_name, gcode_file, subtask_id, task_id,
project_id, design_id, profile_id, model_id, gcode_state,
gcode_file_prepare_percent) and rewrites net.info[*].ip to 0.0.0.0
(matches the #1429 VP bridge fix); then the JSON runs through the same
DB-derived sensitive_strings sanitizer the log path uses, catching any
printer name / serial / access code / cloud email that leaked into a
nested string field.
print.cfg, print.option, ams, vt_tray, vir_slot, mapping,
ams_extruder_map, and hardware fields are all preserved — those are the
fields per-model work needs.
Always-on inside the existing debug-logging-required gate; no opt-in
toggle (the bundle is already user-initiated and downloads locally
before the user chooses to send).
slice_and_persist writes a .gcode.3mf ZIP container but persisted the row
with file_type="gcode". The G-code preview endpoint short-circuits on
file_type == "gcode" and returns the bytes as text/plain, so the embedded
viewer received the raw ZIP body instead of the embedded toolpath.
- Persist file_type="gcode.3mf" on sliced rows (matches _classify_file_type
and external-scan rows).
- get_gcode also routes to the unzip branch when the filename ends with
.gcode.3mf, so rows already written under the bug self-heal on first
preview without a DB migration.
- Extend FileManagerPage badge + viewer-eye gate and ProjectDetailPage badge
to accept "gcode.3mf"; isSlicedFilename / isSliceableFilename already do.
- Add test_library_get_gcode_recovers_legacy_gcode_type_for_3mf: legacy
row preview must be text/plain, contain G28, and NOT start with PK.
Bundle import never delivered what it implied: BambuStudio's .bbscfg export
strips system processes/filaments, so importing a bundle left users without
process presets and slicing fell back to embedded settings on STL. Bundle
mode also hid the standard tier behind a constrained dropdown, the actual
trap reported here.
Removed end-to-end:
- backend: POST/GET/DELETE /slicer/bundles*, SliceRequest.bundle,
SliceBundleSpec, dispatch fork in library.py, bundle-context params on
the filament-requirements endpoints, bundle-fingerprint cache key in
slice_preview.py, SlicerApiService.{import,list,get,delete}_bundle and
slice_with_bundle, BundleSummary / BundleNotFoundError.
- frontend: BundlePicker + BundleStringDropdown, isBundleMode + every
branch, bundle state/queries/dispatch in SliceModal.tsx, SlicerBundle /
SliceBundleSpec types, three bundle API methods. buildCompatibilityIndex
loses its bundle path; presetCompatibility keeps compatible_printers
plus the @BBL fallback.
- SlicerBundlesPanel turns into a permanent static notice explaining the
removal, alternative import paths, and the new slice-time lookup order
(Imported > Orca Cloud > Bambu Cloud > Standard sidecar fallback).
- i18n: slicerBundlesRemoved.{title,description,alternatives,lookupOrder}
translated across all 11 locales; slice.bundle*, slicerBundles.* keys
removed.
Fixed (surfaced by removing bundle mode):
- _resolve_cloud and _resolve_orca_cloud now force type per slot and pin
from: "system" on the payload before json.dumps. Bambu Cloud ships
type as "printer"/"print" and routinely empty `from`; the BS CLI's
--load-settings parser rejects both with return -5 / "input preset
file invalid". Standard tier already did this; cloud paths now match.
Round 2 fixed the model-mode FilamentOverride: tray_info_idx →
sub-brand, plus a material-disambiguated colour name from a new
/inventory/colors/by-material endpoint. The printer-mode panel that
renders the same 3MF (FilamentMapping) was reading the same raw
fields — item.type for the required label, getColorName(item.color)
for the swatch tooltip — and was not touched, so picking "Specific
Printer" still showed "Required: PLA - Black" for a slice the
"Any H2D" branch already labelled "Bambu PLA Matte - Charcoal".
Extract the three-query resolution machinery from FilamentOverride
into a shared hook useFilamentLabels (returns positional
{resolvedName, colorLabel} per slot). Both panels call it; both
read the same labels. The hook also owns extractMaterialHint so the
"strip leading brand token" rule has one source of truth.
FilamentMapping required-side now reads {resolvedName} instead of
{item.type}; swatch tooltip reads `Required: {resolvedName} -
{colorLabel}` instead of `Required: {item.type} -
getColorName(item.color)`.
Native installs that follow the systemd template
WorkingDirectory=/opt/bambuddy
Environment="DATA_DIR=/srv/bambuddy/data"
(or any layout where DATA_DIR is not a subdirectory of the install)
could not apply in-app updates. Every git subprocess in _perform_update
used cwd=settings.base_dir and safe.directory={base_dir}. On standard
installs (DATA_DIR=INSTALL_PATH/data) this happened to work by accident
because git walks up from a subdirectory of the repo to find .git; on
separate-mount layouts the walk has nowhere to go and every call
returns "fatal: not a git repository." safe.directory was also wrong
even on the standard install -- it must equal the repo root git
discovers, not the data dir.
Resolve app_dir = settings.app_dir at the top of _perform_update and
route all four git subprocesses (remote get-url, remote set-url, fetch,
reset --hard) and the embedded safe.directory through it. Rename the
base_dir parameter on _origin_points_at_repo to app_dir so the
signature documents the contract.
Four #1712 issues from the 2026-06-04 Orca Cloud integration:
(1) Tier order put Orca Cloud above everything across SliceModal,
auto-pick scoring, dropdown groups, the AMS slot picker, and the
backend precedence. Bambu-Cloud-only users saw their profiles
deprioritised behind an empty Orca tier.
(2) Cross-tier dedup hid a same-named preset in all but the highest-
priority tier. A user with both a local-imported and an Orca-synced
"Bambu PLA Basic" couldn't see the Orca copy as a picker option.
(3) CloudStatusBanner nagged signed-out users with a permanent
"Sign in to Orca Cloud" line at the top of every slice -- even after
explicit logout. Bambu Cloud had the symmetric problem.
(4) ConfigureAmsSlotModal source badges were inconsistent: Orca rows
showed only "Custom" (no source identity), Bambu Cloud built-in rows
had no badge at all, and the orthogonal isUser-driven "Custom" badge
collided with the source badge for cloud user presets.
Order is local > orca_cloud > cloud > standard everywhere it lives
(SliceModal SLICE_MODAL_TIER_ORDER + TIER_BONUS + dropdown tier list,
ConfigureAmsSlotModal sourceOrder, and backend precedence). The order
drives auto-pick + visual group rendering; it does NOT hide profiles.
_dedupe_by_name replaced with _enrich_cloud_metadata: every tier
returns its full list across all three slots (printer / process /
filament). The function still backfills Bambu Cloud filament metadata
from same-named local / orca_cloud / standard entries so cloud
filaments score in pickFilamentForSlot.
CloudStatusBanner silently no-ops on not_authenticated for both clouds;
expired / unreachable still surface. The not_authenticated i18n keys
stay in the locale files dormant.
ConfigureAmsSlotModal: one source badge per row, one colour per source
(green Local / purple Orca Cloud / bambu-blue Bambu Cloud / amber
Built-in). The legacy isUser-driven "Custom" badge is gone; every row
identifies its tier consistently.
The slot card on PrintersPage shows slot_preset_mappings.preset_name
first in its display fallback chain. Three write paths swap which
spool occupies a given slot:
- internal manual assign (inventory.apply_spool_to_slot_via_mqtt)
- internal RFID auto-assign (spool_tag_matcher.auto_assign_spool)
- Spoolman RFID sync (main.auto_sync_spoolman_ams_trays)
Only the first one was reconciling the row. After an RFID-driven
spool change, the card kept surfacing the previous spool's preset
name until the user opened Configure Slot manually.
Reporter saw H2D-1 / AMS-B3 displaying "Bambu PLA Silk+" for a
freshly-inserted Bambu PLA-CF spool. The matching row in
slot_preset_mappings was last written in March when a PLA Silk+
spool had been in that slot - confirmed live in the database.
New backend/app/services/slot_preset_writer.py exposes a primitive
upsert_slot_preset plus two derivation wrappers: one for the
internal Spool ORM object, one for the Spoolman API dict shape.
All three call sites now go through the helper, so the row stays
in lockstep with the assigned spool regardless of inventory mode.
Bug shape exists in both inventory modes and the patch fixes both
per feedback_inventory_modes_parity. The Spoolman path was latent
for users who'd never manually picked a slot preset; the same
"stale row overrides correct catalog name" symptom appeared for
those who had.
Existing stale rows self-heal on the next RFID-driven swap.
datetime.fromtimestamp(ts) and datetime.now() return naive local
datetimes; .isoformat() then emits no tz marker. The frontend's
parseUTCDate helper appends 'Z' to bare strings, treats the value
as UTC, then converts to local for display — applying the local
offset twice. Reporter on UTC+3 saw boot_time +3h ahead while
uptime was correct (uptime is a backend-side delta of two
naive-local values, so the missing tz info cancels out).
Fix: pass tz=timezone.utc to datetime.fromtimestamp and
datetime.now in system.py's boot_time / uptime path, plus the two
adjacent generated_at sites in system.py and support.py.
close_all_connections() only disposes the engine's connection pool —
asyncio tasks like print_scheduler.run() and the smart-plug snapshot
loop wake on their 30 s cadence and lazily reopen pool connections
holding RowExclusiveLock on print_queue / smart_plug_energy_snapshots.
The restore's DROP TABLE ... CASCADE pass needs AccessExclusiveLock on
every public table, producing an AB/BA deadlock that rolls back the
entire restore transaction.
Reproduced 2026-06-09 restoring a native install's backup into a fresh

Process Y waits for RowExclusiveLock on relation 110182
Fix:
- Layer 1: pause print_scheduler / smart_plug_manager /
notification_service / background_dispatch via their existing stop
affordances before close_all_connections(), with a 1.0 s sleep for
in-flight loop iterations to release sessions. Restore handler
already requires a container restart on success, so the paused
services come back via the next lifespan startup.
- Layer 2: prepend SET LOCAL lock_timeout = '10s' to the begin-block
in _import_sqlite_to_postgres so any reactive writer (per-printer
MQTT, hourly AMS history recorder) that slips through the pause
window fails fast and visibly instead of producing a new deadlock.
Two complementary surfaces for the most-missed install step ("Store sent
files on external storage"):
1. Connection diagnostic check (printer-side variant)
- Reads state.store_to_sdcard, parsed from MQTT home_flag bit 11.
- Pass / fail / skip; instant, no I/O.
- Catches the newer-firmware variant where the toggle moved onto the
printer itself (P2S 01.02 / Studio 2.6+).
An FTP upload-and-verify probe was tried first and rejected. /cache
is always writable from Bambuddy regardless of the slicer setting;
only BambuStudio's own behaviour changes when the toggle flips.
Empirically confirmed against X1C + H2D with the slicer option
toggled off: probe still succeeded, home_flag bit 11 stayed True.
2. Archives-page banner (slicer-side variant)
- The slicer-side toggle is invisible to the printer — older
BambuStudio doesn't push the change to the printer. The diagnostic
can't see it.
- Symptom is deterministic: archiver creates rows with
extra_data.no_3mf_available=True (main.py:2770) when it can't pull
the 3MF from /cache after a slicer-initiated print.
- New endpoint GET /archives/no-3mf-warning returns whether any
archive in the last 30 days has the flag (excluding soft-deleted).
- Amber dismissible banner at the top of /archives; one-shot
localStorage dismissal (matches Layout.tsx update-banner pattern,
but persistent across sessions).
- React-Query disabled after dismissal so the endpoint isn't polled
once the user has been told.
(#1687 part 4, reported by @IndividualGhost1905)
Reporter clarified after part 1 shipped that point 2 wasn't about
archive `tags` (which describe the model — home decor, toys), but
about failure-cause classification on the *log* row itself:
spaghetti, jam, bed-adhesion, etc. Different surface, different
lifetime.
The data field he wanted already existed. PrintLogEntry.failure_reason
is a String(100); the Failure Analysis widget already groups by it;
the Archive Edit modal already mirrors archive.failure_reason into
the most recent log entry (archives.py:1421, shipped with #1444).
The only gaps were:
1. The GET endpoint silently dropped failure_reason (and archive_id
and created_by_id) from PrintLogEntrySchema construction even
when set in the DB — so the Print Log table couldn't render what
the Failure Analysis widget grouped by. Fixed independently of
the editor; regression test added.
2. Orphan log entries (no archive — dispatch errors, aborts before
archive creation, manual entries) had no edit path at all because
the Archive Edit modal cannot reach them. The new endpoint is
the only way to classify those rows.
Changes:
- Backend: new PATCH /print-log/{entry_id} taking
{failure_reason, status}, gated on require_ownership_permission(
ARCHIVES_UPDATE_ALL, ARCHIVES_UPDATE_OWN) — same ownership shape
as the per-row DELETE. Validates against the same 11-key failure
vocabulary and 5-key status set the Archive Edit modal uses;
unknown values return 400 rather than getting stored as raw text
(the i18n layer maps the value back through the vocabulary,
unrecognised values would render as literal strings).
Empty-string failure_reason stores back as NULL so the column's
nullable=True intent is preserved end-to-end. GET endpoint now
surfaces failure_reason, archive_id, created_by_id.
- Frontend: FAILURE_REASON_KEYS moved to an export from
EditArchiveModal.tsx so the new editor reuses the exact same
vocabulary — backend and frontend stay in lockstep. Pencil icon
beside the existing trash icon on every Print Log row, opens a
compact two-field modal (status + failure reason). Save
invalidates print-log and archives-stats query keys so the
Failure Analysis widget reflects the re-classification on the
same response cycle. Failure reason rendered as a sub-label under
the status badge, matching PrintLogTable.tsx's convention.
- i18n: 10 new keys (editEntryTitle, editEntryDescription,
entryUpdated, entryUpdateFailed, archives.permission.noEdit, plus
a 5-key statuses block) translated across all 11 locales. No
English fallbacks.
- Wiki: features/print-log.md gains per-row actions section,
updated permissions table, PATCH/single-DELETE endpoint docs.
When the user clicked Print Anyway on a filament-deficit warning, the
acknowledgement was one-shot. The route cleared manual_start and
filament_short, then the next scheduler tick re-ran
compute_deficit_for_queue_item against identical spool state, found
the same deficit, and re-set both flags. The item bounced between
"user said anyway" and "scheduler re-blocked" — every Play click
returned 409, every confirm got rolled back on the next tick.
Add a persistent acknowledgement flag on the queue item:
- New column `skip_filament_check` on print_queue. SQLite + Postgres
migration branched on is_sqlite() so Postgres doesn't reject
DEFAULT 0 on BOOLEAN.
- PrintQueueItemCreate + PrintQueueItemResponse schemas + the
TypeScript types carry the field.
- POST /print-queue/{id}/start with skip_filament_check=true now
ALSO sets item.skip_filament_check = True (not just clearing
manual_start / filament_short).
- PrintScheduler._block_on_filament_deficit short-circuits to
False — no compute, no flag-setting, no notification — when
item.skip_filament_check is True. We trust the operator's
decision and stop fighting them.
- PrintModal at queue-creation time threads
skip_filament_check=true into the create payload when the user
clicks Print Anyway on the frontend deficit warning, so a print
that was warned-then-acknowledged at add-to-queue time goes in
pre-acknowledged — scheduler never blocks it on first tick.
Flag is not auto-cleared on spool swap by design: if remaining is
now sufficient, the check returns no deficit anyway, so the flag
is moot. Auto-clearing would add lifecycle complexity without
changing behaviour.
AMS Backup awareness (the other half of the discussion) intentionally
NOT included — verified the H2D's bit-26 of print.cfg toggles with
the printer-side AMS Backup setting, but the X1C's cfg has a
different shape entirely and verifying every model family isn't
realistic. Silently under-warning would be worse than always
per-slot. The check stays single-slot for now.
System -> Uptime / Boot Time read psutil.boot_time(), which on shared-kernel
containers (Docker, LXC, Proxmox containers) is /proc/stat:btime - the host
kernel's boot time, not the container's. Reporter on Proxmox LXC saw the
Proxmox node's uptime instead of the Bambuddy container's.
PID 1 is the container's entrypoint (or the host init on bare metal), and
its create_time is the POSIX wall-clock timestamp of when it started.
Switching to psutil.Process(1).create_time() reports the right value on
containers and matches host boot within a sub-second on bare metal.
Defensive fallback to psutil.boot_time() on psutil.Error / OSError so the
endpoint still returns 200 with the best-available answer if /proc/1/stat
is unreadable (locked-down container, custom seccomp policy).
Reporter noted the existing "Also remove this print from Quick Stats"
toggle at archive delete is one-shot: if you kept stats then, there was
no later way to drop the row; and rows without a backing archive
(errors, aborts, manual entries) had no delete affordance at all.
Backend: DELETE /print-log/{entry_id} mirrors delete_archive's
ownership flow via require_ownership_permission(ARCHIVES_DELETE_ALL,
ARCHIVES_DELETE_OWN). Owners drop their own rows; admins drop any row;
missing IDs return 404 rather than 200-silently. /archives/stats
aggregates over PrintLogEntry, so the filament / time / cost / count
contribution drops out of Quick Stats in the same response cycle. The
linked archive (if any) is untouched - the log row is a sibling, not a
child.
Frontend: trash icon next to the filament cell on every row, gated on
the same permission shape as the archive trash. Confirm modal -> row
gone. Mutation invalidates both print-log and archives-stats query
keys so the totals re-render without a manual refresh.
#1687 also asks for per-row tagging (already covered by
EditArchiveModal's tags field) and per-row filament-usage-history
edits (deferred - "restore deducted grams" is only consistent for the
most recent usage row per spool; needs a separate design call).
Reporter wanted to slice via the Bambu Studio sidecar but open files
locally in OrcaSlicer. preferred_slicer drove both the in-app
SliceModal sidecar selection AND the desktop "Open in Slicer" URI
handoff, so picking one forced the other.
New open_in_slicer setting (str | None) drives only the desktop URI;
null inherits from preferred_slicer so existing installs behave
identically. Storage in the existing app_settings key/value table;
GET normalises the "None" string back to null mirroring the
default_printer_id convention.
Frontend: Settings -> Slicer card adds a second dropdown ("Open in
Slicer" with "Same as API slicer" / Bambu Studio / OrcaSlicer);
ArchivesPage, MakerworldPage, ModelViewerModal switch desktop-URI
call sites to open_in_slicer ?? preferred_slicer. MakerworldPage's
"Slice in {{slicer}}" label additionally branches on useSlicerApi
so the label matches what the button actually dispatches.
Reporter on a multi-printer farm with 40+-plate runs needed to walk to
the printer with the right physical plate, but the queue and the
scheduling modal didn't surface curr_bed_type the way the archive card
already did.
New utils/threemf_tools.extract_bed_type_from_3mf helper (per-plate) so
both the queue API and the /plates endpoint can return per-plate values.
PrintQueueItemResponse.bed_type populated from archive.bed_type /
library_file.file_metadata['bed_type'] as the default, then overridden
per-plate via the helper when item.plate_id is set. /archives/{id}/plates
(and library equivalent) include bed_type in each plate object.
Per-plate accuracy matters because archive.bed_type is captured at
ingest as only the first plate's value (services/archive.py:235) -
a 40-plate 3MF mixing PEI + Engineering returns PEI at the archive
level for every plate. The helper re-reads the 3MF and returns the
truth.
Frontend: queue card meta row + PlateSelector per-plate row + PrintModal
header all render bed icon + canonical label via the existing
getBedTypeInfo() helper, same as the archive card.
The runtime services (SSDP, MQTT bind identity, cert subject) already
advertise the target printer's serial via target_printer_serial or
self.serial in proxy mode, but the API response that drives the VP
settings card always returned the self-generated suffix-based serial.
The card therefore displayed a serial that didn't match what slicers
see, breaking the "one identity per VP" mental model.
_vp_to_dict now resolves vp.target_printer_id -> Printer.serial_number
when mode == VP_MODE_PROXY and substitutes the result into the response
serial field. Archive / queue / review keep the self-generated serial
(those modes never speak the target's identity). Orphaned target falls
back to self-generated so the card still renders.
Bambuddy's project_file MQTT payload hardcoded "nozzle_offset_cali": 2 (skip),
giving users on H2D / H2D Pro / H2C / X2D no way to control the same toggle
BambuStudio exposes. Critical for diamond-nozzle setups that must keep the
calibration off.
start_print() now takes a nozzle_offset_cali kwarg; the value is encoded as
1 (run) or 2 (skip) and gated on is_dual_nozzle so single-nozzle machines
always send 2 even if a stale flag arrives. The kwarg threads through
printer_manager, both background_dispatch sites, and print_scheduler so
every dispatch path respects the per-item setting.
print_queue gains a nozzle_offset_cali column (DEFAULT TRUE, is_sqlite()
branch for Postgres BOOLEAN). Settings default key default_nozzle_offset_cali
defaults to TRUE to match BambuStudio. Schemas updated across print_queue,
library FilePrintRequest, archive ReprintRequest, settings.
PrintModal renders the new toggle only when the selected printer is dual-
nozzle (printer-mode: nozzle_count===2; model-mode: DUAL_NOZZLE_MODELS).
SettingsPage default-print-options row + QueuePage bulk-edit tri-state both
hide unless any registered printer is dual-nozzle. Labels reuse the existing
settings.default* keys so the only new i18n strings are
settings.defaultNozzleOffsetCali / Desc and queue.bulkEdit.nozzleOffsetCali
- real translations in all 11 locales.
The print log's User column came from printer_manager.get_current_print_user,
but only background_dispatch (Archive Print, Library Print) ever populated
that dict. The Queue manual-start path went straight from
POST /queue/{id}/start into PrintScheduler._start_print, neither end
recording the clicker — so any print started from the queue landed in
PrintLogEntry with created_by_username NULL even with auth enabled.
Two-sided fix: /start now writes user.id to item.created_by_id when no
prior owner is set (preserves UI-added items' original uploader), and
PrintScheduler gains _propagate_owner_to_printer_manager called from
_start_print to hand the owner into set_current_print_user before the
print command goes out.
asyncio holds only a weak reference to tasks returned by
``create_task``. Fire-and-forget callers that discard the return value
let the event loop GC the task before it finishes, logging
``Task was destroyed but it is pending!`` with no traceback. The #1648
support-bundle review surfaced 94 such warnings in 8 days of v0.2.4.5
-- the silently-vanished exceptions reach support bundles as opaque
GC notices instead of actionable errors.
New backend/app/core/tasks.py::spawn_background_task(coro, *, name=None)
is the one place in the codebase that calls asyncio.create_task. It
stores the task in a module-level set, attaches a done-callback that
auto-removes on completion AND surfaces any uncaught exception via the
logger with the originating traceback, and accepts name= so a leak
source is traceable through /tracebacks and the log line. Cancelled
tasks don't log (a shutting-down service is not an error).
Migrated the 16 truly-orphan create_task call sites to the helper:
main.py (8):
reconcile-stale, cooldown-poweroff, energy calc, smart-plug,
maintenance-check, photo-then-notify, layer-timelapse,
scan-timelapse, print-scheduler, notify-no-archive (the last one
was hand-rolling the same pattern with task + no-op done_callback)

Sites that already kept strong refs are unchanged:

Reporter on an H2D + Polymaker PLA Matte spool noticed that assigning
the spool from the Dashboard left the slicer's filament dropdown
showing "unknown", but clicking Configure right after made the
slicer recognize it correctly. "Configure" felt like a mandatory
follow-up step rather than a refinement.
Bambu cloud uses three preset-ID shapes:
GFS… — Bambu official cloud preset
PFUS… — cloud user-created preset
PFCN… — cloud shared / partner preset (Polymaker's "(Custom)"
Bambu Lab H2D variants ship this prefix)
apply_spool_to_slot_via_mqtt only routed GFS and PFUS through the
cloud-detail lookup that extracts the underlying filament_id. PFCN
slipped past the cloud-lookup branch, fell into the local-preset
int() parse path, raised ValueError, dropped into
normalize_slicer_filament which returns any P-prefix unchanged, and
the raw PFCN landed in tray_info_idx. The printer's calibration
table can't index that, so the slicer rendered "unknown". The
Configure modal rescued every assign because it does its own
getCloudSettingDetail and writes the resolved filament_id.
Extend the cloud-detail-lookup branch (inventory.py:129) and the
discard safety net (inventory.py:223) to include PFCN alongside
GFS/PFUS. Three behaviours fall out:
* Cloud-authenticated: the real filament_id from
detail["filament_id"] ships as tray_info_idx (Polymaker PLA
Matte resolves to GFL05).
* Cloud unavailable: raw PFCN discarded, the slot reuses an
existing valid P-prefix preset if material matches.
Source comment now lists all three cloud-ID shapes so the next time
Bambu invents a new prefix the maintainer doesn't have to re-derive
the structure from a bug report.
Non-proxy VPs (Archive / Review / Queue) with a target printer set up
a live-mirror bridge that forwards the slicer's MQTT and RTSPS auth
bytes through to the real printer. The slicer holds one code in its
profile (the one it bound the VP with), and that code has to satisfy
both the VP listener and the real printer at the far end of the
bridge. If the codes diverge the bridge silently fails at the second
hop — slicer reaches .49:8883, FINs before sending a ClientHello,
retries identically. The wiki framed the code-match requirement as a
camera-only concern; it isn't, all bridged protocols inherit.
Fix removes the foot-gun instead of re-documenting it. When a target
is selected on a non-proxy VP the access-code field switches to a
read-only display showing the target's code with an Eye-toggle
reveal; the backend auto-inherits on every create / update (any
explicit access_code submitted alongside a target is silently
overridden as belt-and-braces for non-UI clients). The required-when-
enabling check now treats target-set as satisfying the access-code
requirement. Standalone (no-target) non-proxy VPs still get the
editable input + Save button.
One-shot startup migration corrects any pre-existing mismatched
rows: SELECTs diverged VPs and logs one INFO line per row for the
audit trail, then UPDATEs via correlated subquery. Idempotent and
portable between SQLite and Postgres.
Reporter linked a NAS and the auto-imported files drowned their own
Bambuddy uploads in the "All Files" sidebar listing. There was no filter
to escape it — only per-folder clicks. Restore the pre-external semantics:
"All Files" now lists managed-storage files only. The combined
across-every-external view moves to a new sibling sidebar entry,
"External", that only appears when at least one external folder is linked.
Backend: GET /api/v1/library/files gains internal_only and external_only
query flags. Filter is on LibraryFile.is_external. Both flags set is a
400, not a silent pick-one.
Frontend: new topLevelView state on FileManagerPage (default internal);
the query passes the scope only when selectedFolderId is null. Mobile
selector dropdown uses __top:internal / __top:external sentinels so the
same state round-trips through option values. Empty-state copy
distinguishes internal-empty from external-empty.
Reported and root-caused by @needo37. Importing a model via the MakerWorld
URL-download feature into a writable external folder (e.g. SMB/NFS-mounted
NAS) saved the 3MF into Bambuddy's internal managed library dir, not the
external mount. The file card showed in the File Manager under the
external folder, but the bytes never landed on the NAS, and the on-disk
copy was UUID-renamed so a find by the original basename matched nothing.
Root cause was save_3mf_bytes_to_library at backend/app/api/routes/library.py:422:
it accepted folder_id but never loaded the folder, never inspected
is_external / external_path, hardcoded the destination to
get_library_files_dir() with a UUID name, and left the LibraryFile row
with is_external=False. So the row's folder_id pointed at the external
folder while its bytes and is_external flag both said "managed/internal".
Same class of bug as #1112, which had been fixed for the multipart-upload
and move paths but never applied to this byte-import path.
Fix mirrors the multipart-upload path directly:
- Load target_folder from folder_id when non-None.
- Feed it to _resolve_upload_destination(target_folder, filename), which
already returns (dest, is_external) and enforces the 403-read-only /
400-unwritable-or-missing / 409-collision rejections.
- Write bytes to dest (real filename for external, UUID for managed).
- Persist the row with file_path=_stored_file_path(dest, is_external)
and is_external=is_external.
The route-layer read-only guard at makerworld.py:256-260 is preserved -
it returns the friendlier error before the upstream download burns
bandwidth - and _resolve_upload_destination's identical check stays as
defence-in-depth for any future caller that skips the route gate.
Thumbnails continue to live under the managed get_library_thumbnails_dir()
regardless of the 3MF's location, matching the upload path.
The old endpoint name implied that calling it would drop weight_used to
0. In practice it only stamps weight_used_baseline = weight_used so the
Inventory page's "Total Consumed" widget (weight_used - baseline) reads
0 going forward, while remaining (label_weight - weight_used) is
preserved. Calling the endpoint via curl and seeing weight_used
unchanged in the JSON response is confusing.
New paths:
- internal: /api/v1/inventory/spools/{id}/reset-consumed-counter
/api/v1/inventory/spools/reset-consumed-counter-bulk
- spoolman: /api/v1/spoolman/inventory/spools/{id}/reset-consumed-counter
/api/v1/spoolman/inventory/spools/reset-consumed-counter-bulk
Behaviour is unchanged in both modes; internal stamps the baseline
directly, Spoolman-mode PATCHes upstream used_weight=0 and the
_map_spoolman_spool read mapping reconstructs the same "displayed
consumed = 0, remaining unchanged" Bambuddy-visible shape. Parity
between modes was already in place and is preserved.
The Spoolman-client method reset_spool_usage keeps its name because it
describes what is sent upstream to Spoolman, not what Bambuddy's
endpoint promises to callers.
Frontend:
- api.resetSpoolUsage / bulkResetSpoolUsage (and Spoolman variants)
renamed to resetSpoolConsumedCounter / bulkResetSpoolConsumedCounter.
- Button labels: "Reset usage to 0" -> "Reset counter" / "Reset all
counters" (short, unambiguous); tooltips and confirm-modal bodies
still spell out the full semantics.
The existing connection diagnostic proved TCP + TLS + auth + SUBSCRIBE but
not that the printer was actually publishing reports. A wrong-cased serial
passes mqtt_auth because the broker accepts the subscription regardless;
the user-visible symptom is empty AMS / no K-profiles / no custom filaments
in the slicer Device tab because the VP cached state is empty. Bambuddy
already logged the actionable hint at bambu_mqtt.py:498 but only to
container logs.
New printer_publishing check turns that warning into a structured
diagnostic result. Pass = bridge has seen at least one report since the
last (re)connect; fail = zero reports across the wait window with fix-text
pointing at the case-sensitive serial. Bounded 10s poll on the on-demand
UI route, no wait on the support-package gathering path so bundling stays
fast. Exits the moment a message arrives — typical wall-clock is 1-2s.
Frontend renders an elapsed-seconds counter plus a "Listening for status
report — up to 10s" hint during the pending state so the wait doesn't look
hung. PUBLISH_WAIT_DEFAULT_SECONDS pinned on both sides.
report_messages_since_connect exposed as a public property on
BambuMQTTClient so the diagnostic doesn't reach into private state.
The Scheduled Local Backups time-of-day picker was interpreted as UTC by
_calculate_next_run, so a UTC+3 user had to enter 18:00 to get a 21:00
local backup. The UI labeled the field "UTC" but it was still surprising.
Picker is now interpreted in the container's local timezone, resolved
from the TZ env var via zoneinfo.ZoneInfo (same source the Support page's
environment.timezone shows). UTC fallback when TZ is unset or
unrecognised. The /local-backup/status endpoint exposes the resolved
zone, and the UI renders it next to the field via a new
backup.localTimeHint i18n key with real translations in all 10
non-English locales.
One-time behaviour change for users who entered a UTC time as a
workaround: the first scheduled cycle after upgrade will run at their
local TZ offset earlier than expected. Re-enter the time as local once
and it is correct from then on. No migration is shipped; migrating
around a DST boundary would be ambiguous.
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.
