maziggy aef4f3a3e9 fix(oidc): strip the required BAMBUDDY_OIDC_* values and register the local-login bypass
A Kubernetes Secret written as a block scalar carries a trailing newline, and
the schema bounds the four required variables by max_length only, so an
unstripped issuer_url was stored and enabled and then raised httpx.InvalidURL
on the first click of the SSO button -- the authorize-time failure the
all-or-nothing rule exists to prevent. Whitespace-only values got through the
same way, contradicting the reader's own "an empty required var counts as
unset". The optional variables have always treated blank as unset; the
required ones now do too.

Also registers BAMBUDDY_LOCAL_LOGIN (#1589) in the typo guard, which logged
"possible typo" for it on every boot while listing every BAMBUDDY_OIDC_*
variable as legitimate.

MarianandClaude Opus 4.8 9e783fbad6 fix(oidc): keep the local-login bypass lenient under strict env_bool
Promoting env_bool to strict rejection made BAMBUDDY_LOCAL_LOGIN=on raise
EnvOIDCConfigError uncaught on the login/forgot-password path -- a 500 on
the exact recovery endpoint the bypass exists to keep open. env_bool gains
a strict flag (default True for the startup OIDC reader); the local-login
caller opts out so an unrecognized value falls back to "off" instead.

Marian 77c9bdd694 fix(oidc): reject an unrecognized boolean instead of guessing
_env_bool returned the default for anything outside {true,1,yes}, so
BAMBUDDY_OIDC_REQUIRE_EMAIL_VERIFIED=on silently read as OFF and
BAMBUDDY_OIDC_ENABLED=on silently disabled the provider -- the exact
opposite of what .env.example claimed. Unrecognized values now raise
EnvOIDCConfigError, caught in _apply_env_oidc_provider the same way a
bad DEFAULT_GROUP or a ValidationError already is: logged and left
running, never released on a typo.

Also promotes _env_bool to env_bool now that it has a call site in
auth.py, and corrects the boolean-parsing sentence in .env.example.

Marian c547505c64 fix(oidc): treat a blank optional env var as unset, not a refusal
BAMBUDDY_OIDC_SCOPES, _EMAIL_CLAIM and _ICON_URL fell back to their
default only when the key was absent, so `BAMBUDDY_OIDC_ICON_URL=` in
a compose file (as .env.example ships it, commented) reached the
schema validator as an empty string and got the whole provider
refused. default_group already treated blank as unset; these three
now follow the same rule.

maziggy 4f2c073a34 fix(vp): gate the slicer's AMS pick behind the toggle and scope its badges (#2700)
Round-3 review of the "Save AMS mapping" PR.

The queue item's ams_mapping was set unconditionally, on the reasoning that
honouring the slicer's own pick is a correctness fix rather than a feature.
It is both. Storing a resolved mapping makes _ensure_ams_mapping return
early, so _compute_ams_mapping_for_printer never runs — and that function is
where prefer_lowest_filament lives, along with the AMS-filament-backup gate
that qualifies it (#1766), the inventory-remain overrides, and the per-slot
force-colour overrides. Every existing queue-mode VP pointed at a printer
would have quietly lost all of it on upgrade, without a setting to turn it
back on.

So save_ams_mapping now gates the queue item too, not just the archive
persistence. Off is exactly the old behaviour. The correctness case the PR
was written for — two spools of the same red PLA, and the slot the user
picked in the slicer thrown away — is still fixed, for anyone who asks for
it.

Force color match wins over it when both are on. Its only effect on a
fixed-printer item is the filament_overrides written onto the queue item,
and those are read inside the function a stored mapping skips, so the two
toggles sitting next to each other on the same card silently cancelled. The
dispatch now matches strictly, as asked, while the slicer's pick is still
saved onto the archive — that is what the toggle's name promises, and a
later reprint is a separate decision from this print. The queue-add fallback
applies the same rule to a request that carries force-colour overrides.

A mapping shorter than a plate's highest slot id cannot address that plate's
own slots, and _ensure_ams_mapping would have kept it anyway, since it only
rejects an all-unresolved one. Each plate now checks the length it needs and
falls back to a computed mapping if the array does not reach. Bambu Studio
sends a file-global array, so this normally never fires; it also means a
multi-plate Send All degrades safely if that ever stops being true.

The badges claimed more than they delivered. Both rendered whenever a saved
mapping existed, ignoring which printer it belonged to, while the tooltips
promised the reprint would reuse those exact spools — true only on the
printer the trays were resolved against. The queue row's flag is now
computed against that row's own printer, which is precisely when dispatch
reuses the mapping, and the archive card names the printer instead of
implying any of them will do. It hides itself when that printer no longer
exists. Retranslated in all 13 locales.

Frontend tests, which the PR had none of. The printer-scoping rule is now a
pure function rather than an inline expression, covered for the mismatched
printer, the no-printer-selected case that would otherwise compare undefined
against undefined, and malformed extra_data. The toggle's undo bookkeeping
is covered for unresolved slots, short mappings, and hand-made picks —
preserved when the toggle never wrote that slot, replaced when it did, which
is behaviour worth pinning either way.

Also reverts all three queue-mode switches when a save fails, not just the
new one; without it the card shows a setting the server rejected.

MarianandClaude Opus 4.8 6eea61dc78 fix(oidc): survive a failing rollback in the never-raise handler too
The recovery rollback after a failed commit was itself unguarded, so a
rollback that raises on a wedged connection would still take the boot
down -- the exact failure the never-raise contract exists to prevent.
Suppressed; the caller's `async with` discards the session regardless.

maziggy ce3e59884a fix(slicer): bound slices by silence, not by total slicing time (#2730)
A heavy MakerWorld model — one Bambu Studio also takes a long time over —
failed after five minutes with "Slicer sidecar unreachable". The sidecar
was reachable the whole time and still slicing when we hung up on it.

SlicerApiService carried a hardcoded 300s timeout, passed to httpx as a
bare float so it covered connect, read, write and pool alike. On a single
long request that is not a health check, it is a cap on how long a model is
allowed to take. And because httpx.ReadTimeout subclasses RequestError,
expiry landed in the same handler as a refused connection and was reported
as an unreachable sidecar — so the reporter went and updated their sidecar
container, which was never the problem.

The information to do better was already being collected. _poll_progress
polls /slice/progress/{id} once a second alongside the blocking POST to
drive the live progress toast, so at minute five Bambuddy had fresh
evidence the slicer was working. It killed the request anyway.

So the read timeout comes off the HTTP call and the poller supervises
instead: the deadline moves forward on every progress update, and only
genuine silence ends the wait. A model that keeps reporting runs to
completion however long it takes. Connect and pool keep short timeouts —
a sidecar that will not accept a connection is unreachable and should
still say so quickly.

Only a *changed* progress payload counts as alive. The sidecar re-serves
its last snapshot on every poll, so counting repeats would leave the
watchdog unable to detect a stall at all.

The window is floored at three poll intervals: liveness can only be
observed as fast as the poller ticks, so anything shorter would expire in
the gap between two polls and fail every slice instantly.

New setting slicer_stall_timeout_minutes (Settings > Workflow > Slicer),
default 15, range 1-240, alongside the sidecar URL and gated on
use_slicer_api like its neighbours. Sidecars too old to report progress
have no liveness signal, so for those the same number bounds total elapsed
time — the old behaviour, configurable and no longer 300s flat. The
message says which case applies and where to change it.

SlicerTimeoutError is its own type and maps to 504, not 502: the sidecar
answered throughout, we stopped waiting. Connection failures keep
SlicerApiUnavailableError. The preview slice path gets the same treatment.

Marian c4b5d42f48 fix(oidc): log distinctly when env config adopts a UI-created provider
A name collision with a provider that was NOT already env-managed
overwrites its issuer, client id and secret in place and locks it
behind the env-managed 409 -- but it logged the same routine "applied"
line as an ordinary re-apply, giving no signal a UI provider was just
taken over. Adoption is now a WARNING with its own wording; a routine
re-apply of an already env-managed provider keeps the INFO line.

Marian 6dff1e9644 fix(oidc): make apply_env_oidc_provider never raise on DB errors
The db.execute/db.commit calls in the upsert and release paths sat
outside the try/except that only wrapped OIDCProviderCreate, so a
commit failure at startup (connection blip, WAL lock) propagated out
of the lifespan and took the instance down -- the exact outcome this
module exists to avoid. The body now runs inside a private
_apply_env_oidc_provider(), with the public entry point catching,
logging and rolling back on any exception.

maziggy 284709f850 fix(projects): drop deleted prints from their project, and refresh the view (#2731)
Deleting a print that belonged to a project left it on the project page as
a card with a missing thumbnail, and there was no way to remove it.

Deleting a print is a soft delete by default (#1343): the files go from
disk, the row stays so global Quick Stats keeps counting its filament,
time and cost. Every other consumer filters those rows out. The projects
module filtered none of them — the only deleted_at check in the whole file
was for LibraryFile — so a deleted print kept its project_id and kept
being listed, pointing at a thumbnail that no longer existed. The same
broken previews appeared on the overview cards, and in the timeline, where
the entry links to an archive that no longer opens. Unassigning was
impossible because the only UI that can change a print's project lives on
the Archives page, which correctly hides deleted prints: visible on the
project, unreachable from anywhere.

All eight project-scoped archive queries now filter, counts included. That
last part is a deliberate divergence from #1343, where the whole point of
the soft delete is that the contribution survives: a project is a piece of
work with a definite membership, not a lifetime total, so a project that
lists eleven prints must not claim twelve. The reasoning is recorded at
the constant so nobody later "fixes" it back.

remove_archives_from_project keeps working on hidden rows on purpose — it
is the repair path for links written before this. The BOM print_name
lookups are left alone; naming a since-deleted print is still correct.

Two more consumers had the same gap. The CSV/Excel export handed back rows
the interface says are gone — filtered at the base query, since the export
is the list you are looking at saved to a file. Per-project failure
analysis measured a failure rate against prints deleted from the project,
and disagreed with the project's own numbers; only the project-scoped
branch filters, global analysis still counts every run including orphans
as #1390 established.

Finally, the project page needed a manual reload to catch up. staleTime is
60s and the delete mutations invalidated only ['archives'], so a project
visited within the minute served its cached copy, print still there. The
project-assign mutations had the mirror-image bug: ['projects'] refreshed
the overview cards but never ['project', id]. Both now go through one
shared helper covering every project-derived key, as bare prefixes so all
cached project ids are matched.

Sergey Dontsov 13c37ffe51 fix(vp): scope saved AMS mapping to the printer it was resolved against
Round-2 review fixes for #2700.

Blocking: the toggle didn't actually gate the archive write. archive.py's
promotion fired for any print_data carrying ams_mapping, but bambu_mqtt's
request-topic interception captures ams_mapping unconditionally for every
print source (slicer-direct LAN prints included). Since main.py's
real-printer auto-archive path forwards the full MQTT payload as
print_data, every archive on any install — VP or not — grew
extra_data.slicer_ams_mapping. Fixed by replacing the print_data-sniffing
with an explicit `slicer_ams_mapping` param on archive_print() that only
the VP-queue path (already gated on save_ams_mapping) ever passes.

Blocking: a saved mapping could get reused on a printer it was never
resolved against — tray IDs only mean something relative to one printer's
AMS layout. extra_data.slicer_ams_mapping is now stored as
{mapping, printer_id} instead of a bare array:
- add_to_queue's fallback only fires when the reprint's target printer_id
  matches the mapping's origin printer.
- The frontend's archiveAmsMapping only surfaces (and the Mapping button
  only appears) when the print modal's selected printer matches too.
- A model-based VP (target_printer_id=None, no MQTT bridge to any real
  printer) never stamps a mapping in the first place — there's no live AMS
  layout for the slicer to have resolved tray IDs against.

Also from review:
- Multi-plate archives now get the Mapping button too (the per-plate
  FilamentMapping loop was missing archiveAmsMapping entirely).
- Added coverage for the previously-untested late-MQTT archive patch path
  (_restamp_recent_queue_item), including the model-based-VP skip case.
- usingArchiveMapping now also resets on printer change, not just
  plate/archive (it already worked via the printer-scoping above, but is
  now an explicit dependency too).
- The Mapping button's revert (OFF) now undoes only the slots it itself
  set, not every manual pick in scope — matches the comment above it.
- Added a comment on why negative-value slots (external spool) are
  skipped rather than cleared when applying a saved mapping.

Sergey Dontsov bab1cfb906 feat(vp): per-VP "Save AMS mapping" toggle + reprint auto-apply
Lets a reprint reuse the AMS slot the slicer itself picked, instead of
re-deriving one from the file's static type/color.

When a Print Queue VP has "Save AMS mapping" on, the slicer's own
live-resolved ams_mapping (from the project_file MQTT command) is
persisted onto the archive as extra_data.slicer_ams_mapping. A later
reprint can reuse it via a new "Mapping" button in the filament-mapping
panel — one click snaps every slot to the saved pick, click again
reverts to auto-match. Archive cards and queue rows get an "AMS mapping
saved" badge so it's visible beforehand. add_to_queue also falls back
to the saved mapping automatically when the caller sends no explicit
ams_mapping (e.g. a plain reprint with no per-slot edits).

The queue item's own ams_mapping (used for that dispatch) is still
captured unconditionally whenever the slicer provides it — that part is
a correctness fix, not gated behind the toggle. Only the archive
persistence for future reprints is opt-in.

Split out from the original combined PR per review: this half is
genuinely opt-in and low-risk (#2684). The dispatch-time validation
gate that keeps a stored mapping honest (#1308) changes behaviour for
every existing user and will land as its own PR.

Review fixes applied:
- _extract_slicer_ams_mapping_json: dropped the unreachable `v is None`
  arm and rejected bool explicitly (isinstance(v, int) accepts bool).
- Translated the Russian docstring text to English.
- save_ams_mapping's model comment moved to a trailing comment on the
  column line, matching the file's convention.
- usingArchiveMapping now resets when the plate or archive changes, so
  the Mapping button can't read ON against a mapping it never applied.
- Translated "Click to change slot assignment" and "Re-read".
- add_to_queue's fallback is now called out explicitly in code comments
  and covered by three new integration tests (fallback fires, explicit
  mapping wins, unrelated extra_data doesn't false-trigger).

Closes #2684

maziggy db538e43f1 fix(slice): give the slice modal one filament row per project slot (#2712)
The filament list is positional from the modal down to the CLI's
filament_N.json parts, but for a source that already carries slice_info the
requirements endpoint returns only the slots the plate consumes. A
MakerWorld model declaring four filaments and painting with slot 4 alone
therefore showed one dropdown, whose PETG pick the CLI bound to slot 1 —
slot 4 sliced with the profile baked into the source, and the print came out
PLA.

The endpoint now takes full_slots, which widens that answer to every
project slot with used_in_plate flags, and only the slice modal passes it.
Print-time AMS matching shares the endpoint and keeps the used-only list, so
it still asks for exactly the spools the job needs.

maziggy 83142c726c fix(slice): report a finished slice once, not once per queued poll
setInterval does not await an async callback. Slicing a large project
blocks the backend for seconds, so poll ticks piled up behind one stalled
request, each holding a snapshot taken while the job was still active.
They resolved together, and every one of them ran the completion path —
one toast and two query invalidations each. A 20s stall against the 1.5s
interval produced 13 "Sliced X" toasts from a single slice.

Only one poll round is now in flight at a time, which also stops queueing
requests against a backend that is already saturated. Completion is
recorded once per job id, and a round still awaiting a response when the
effect tears down now returns instead of acting.

Marian ed29319cf9 docs(oidc): drop the upgrade-path claim from the release-path rationale
The two-flagged-row state was never released, so no installation can carry it
in -- the reason to release every flagged row is not repair, it is that the
sweep's invariant is not enforced anywhere and scalar_one_or_none() turns a
broken one into a failed boot. Comment, test docstring and test name say that
instead.

Marian 3c679459e1 feat(oidc): set the default group from the environment, by name
Without it every account auto-created through the env provider fell back to
Viewers (routes/mfa.py), and because the provider is locked the UI could not
correct it either -- a real limitation for a declarative deployment running
BAMBUDDY_OIDC_AUTO_CREATE_USERS=true.

BAMBUDDY_OIDC_DEFAULT_GROUP names a group rather than an id: ids are handed out
per installation, so the same compose file would point at a different group on
the next deployment. The name is matched exactly, resolved against the database
before anything is written, and default_group_id joins _APPLIED_FIELDS so
dropping the variable clears the group again -- the environment is the whole
truth for this row.

A name that matches no group is refused rather than defaulted: silently landing
users in Viewers is the failure this variable exists to remove, and the API
already answers 422 for a default_group_id that does not exist. The refusal is
logged and survivable, and it says which of the two cases happened, because
they differ sharply -- an existing provider keeps running on its last good
config, while on a first boot nothing is created and no SSO button appears.

Raised by maziggy in review of #2625 as a scope decision; documented in
.env.example and in the companion wiki PR.
2026-07-30 14:43:23 +00:00
Marian d64f5d9651 fix(oidc): release the row the env config managed before a rename
apply_env_oidc_provider matches the provider by BAMBUDDY_OIDC_NAME but never
cleared is_env_managed from the row it managed previously. Renaming the
variable therefore left two flagged rows, and both consequences are reachable
by ordinary config edits: the old row stayed enabled with a stale issuer and
secret on the login page while _refuse_if_env_managed answered 409 to every
attempt to edit, disable or delete it -- the dead end reachable only through
the database that the release path exists to prevent -- and unsetting the
variables later hit scalar_one_or_none() on two rows, so MultipleResultsFound
propagated out of the lifespan and the app stopped booting.

The upsert now sweeps the flag off every other row, the same shape the
autologin sweep one block down already uses: disable and release rather than
delete, for the same cascade reason as everywhere else in this branch. The
release path releases every flagged row it finds instead of exactly one -- the
sweep should keep that at one, but a release path that dies with
MultipleResultsFound the moment that invariant breaks is a second way to lose
the boot, and the query costs the same either way.

Releasing now clears is_autologin as well. Without it a released row keeps a
latent autologin claim: update_oidc_provider only re-runs the exclusivity sweep
when a request sets is_autologin=True, so merely re-enabling the row in the UI
would silently make it the autologin target again.

Reported by maziggy in review of #2625, with the rename reproduction.

gzimbric b938b83136 fix(tests): add the new fan fields to the plate-clear status fixture
mqtt_relay reads state.left_aux_fan_speed, but the SimpleNamespace fixture in
test_plate_clear_mqtt_notification enumerates its fields explicitly, so the two
status-payload tests raised AttributeError. I updated the equivalent fixture in
test_printer_manager_status_broadcast and missed this one — running only the
touched suites is what hid it.

Also addresses the round-2 review notes:

- exhaust_fan_present: documented that the H2 series reports part 3 too, so the
  flag is not model-specific despite the name.
- Mask the part id after shifting, matching get_flag_bits(id, 4, 8), for
  consistency with the state decode. No behaviour change for any observed id.
- Noted the unmapped H2 id 6 beside the id branches.
- Reject fan=aux2 when the printer reports no left_aux_fan_speed, so a POST
  against an A1 no longer sends M106 P10 for absent hardware. The UI already
  hid the badge; this closes the same hole on the API.
- Added a test asserting EXHAUST_FAN_LABEL_MODELS and the frontend's
  MODELS_WITH_EXHAUST_LABEL cannot drift apart.

maziggy 5a67dffe4f fix(timelapse): poll longer, diff without a clock, delete once archived (#2704)
Timelapse was on, the video never reached the archive, and Scan for Timelapse
found nothing afterwards. Across 247 support bundles this was the norm, not an
edge case: 457 automatic scans scheduled, 262 attached.

The scan looked four times over ~65s. The attempt that found the video was #1
272 times, then 17 / 13 / 13 — flat against the cutoff, not decaying, i.e.
files were still arriving when we stopped. What ran afterwards searched for the
print name inside the filename; Bambu only writes "video_<timestamp>", so it
fired 159 times and matched zero.

The manual Scan had no baseline at all and matched on filename timestamp, FTP
mtime, or "there is only one video" — all reading a clock a LAN-only printer
cannot sync. The reporter's P1S was six and a half days out.

- Poll for minutes instead of ~65s; drop the name-match fallback.
- Persist the print-start baseline on the archive, so the diff survives a
  restart mid-print and the manual Scan runs the same comparison. With a
  baseline present the clock-based strategies are skipped entirely — they can
  only turn an honest "pick one" into a confident wrong answer.
- When several files are new (a previous print's video landing late), exclude
  the ones already attached to another archive instead of ordering the
  candidates. Ordering could only be done on the printer's clock.
- Delete the video from the printer once archived. Keeps /timelapse to
  unclaimed files, which is what makes the diff unambiguous, and stops P1S
  cards filling with AVIs.
- Gate that delete on a verified transfer: download_file now compares against
  the size from the listing. An FTPS connection closing early does not always
  raise, so a partial buffer was being attached as a complete video — which
  would also have been the one case where deleting the source lost data.

Bounded twice on purpose: wall-clock deadline plus a derived round cap, since
the deadline stops bounding the loop as soon as the sleeps are shortened.
Per-round logging only speaks when the listing changed — 31 rounds of full
listings would bury the interesting line in the support bundle.

Migration adds print_archives.timelapse_baseline as JSON, spelled the same on
both dialects so a migrated database matches a fresh one.

fix(finish-photo): add the timelapse frame to the archive after the notification (#2704)

When a print records a timelapse, its last frame is the better finish photo:
the firmware stops recording with the toolhead parked and before the end
G-code drops the bed, where a live grab at that moment catches a lowered
plate. Bambuddy waited 60s for the video and then gave up, because the
print-complete notification blocks on that photo and holding a notification
for minutes is worse than sending it with the live grab.

P1-series printers write MJPEG AVI rather than H.264 MP4 and serve it slowly.
Measured over 261 attaches in the support bundles: P1S median 33s, p90 167s,
worst 546s, while every other model finished inside 26s. So the printers that
most needed the better framing were the ones that never got it.

Keep the notification on the same bound, and keep waiting off to the side.
_capture_finish_photo_from_timelapse now reports whether it ran out of time or
concluded — a video that landed and failed extraction is not worth retrying,
one that never arrived is. On the first, schedule a background task that waits
up to 15 minutes and inserts the extracted frame at the front of the archive's
photo list, where the gallery opens.

The live grab stays on disk: the notification already links to that exact
file, so removing it would leave a broken image in Discord or Telegram.

The length check proves we received what the listing said, not that the file
was finished. The first look happens ~5s after the print ends, while the
printer may still be writing, so a growing file can be listed short, served
short, and pass. Re-list after the download and only accept the video once its
size has stopped changing — a failed re-list counts as not settled, since
"could not check" must not mean "safe to delete".

and str(exc) embeds input_value=..., leaking BAMBUDDY_OIDC_CLIENT_SECRET into
the logs (maziggy review, PR #2625).

Split the catch: ValidationError logs errors(include_input=False), which
strips submitted values; any other exception logs only its class name, never
str(exc). Rejection stays survivable — a bad config is still skipped and the
app still boots.

Adds two regression tests: an over-long secret is rejected without the value
reaching the log, and a non-ValidationError is survived without leaking its
message.

Marian c163b3524a fix(oidc): identify the env provider by name, and release it when unconfigured
Two problems, both from using is_env_managed as the provider's identity.

An operator who names the env provider after one that already exists hit the
unique constraint on `name` during the insert. That happens inside the
lifespan, so the app did not boot -- from a function whose docstring promises
it never raises. The lookup now matches on the name, which is unique, so an
existing provider is adopted and updated instead of duplicated.

And removing the config left the row disabled but still flagged, so the API
went on refusing every edit and delete while nothing managed it any more: a
dead end reachable only through the database. The flag is now cleared as well,
handing the provider back to the UI. Re-adding the config finds the same row
by name, so the account links it carries survive the round trip.

Falls out of the same change: the issuer URL and client id can be rotated
under an unchanged name without orphaning those links.

Found by Marian asking what happens when you want to change the provider --
the answer was "you cannot, ever again".

Marian c9ee259807 feat(oidc): refuse API writes to the env-managed provider
Startup rewrites this row from BAMBUDDY_OIDC_* on every boot, so an edit
through the UI would be accepted and then silently reverted at the next
restart -- the operator would watch their change vanish with nothing
explaining why. A 409 says so instead.

Covers all four mutating routes, including the two icon ones: the icon comes
from BAMBUDDY_OIDC_ICON_URL and would be restored the same way. Extracted as
one helper rather than four copies of the same check, so a fifth route cannot
be added with the guard silently missing.

Locking it is safe because BAMBUDDY_LOCAL_LOGIN (#1589) remains the documented
recovery path if the provider itself becomes unusable. A test pins that
UI-created providers stay editable -- the lock must not leak onto them.

Marian e7a413e745 feat(oidc): apply the env provider during startup
Placed after init_db(): is_env_managed only exists once run_migrations has
added it, so an upsert before that would fail on every existing installation.

The wiring gets its own tests because the apply tests cannot cover it -- they
call apply_env_oidc_provider() directly, so deleting this call would leave the
feature dead with a fully green suite. Verified: removing the call fails the
three startup tests while all seven apply tests still pass.

They assert against the lifespan's source rather than running it. The function
is ~460 lines and starts printer connections, MQTT and schedulers; executing
it would exercise everything except the line in question. The docstring says
plainly that this proves the call exists and runs after migrations, and
proves nothing about its behaviour.

Marian 58602a3f1b feat(oidc): upsert the env-managed provider
The row is updated in place, never delete-recreated: user_oidc_links
references it with ON DELETE CASCADE, so recreating the provider would
silently unlink every account bound to it. For the same reason, removing the
variables disables the provider rather than deleting it -- the links would not
come back when the config does.

Config goes through OIDCProviderCreate, the schema the API already uses, so
the environment cannot reach a state the UI would have refused. That covers
the SEC-1 auto-link check: auto-link plus unverified email is an account
takeover, and it is rejected here exactly as it is in the UI.

Nothing raises. This runs during startup, so a typo in one variable must not
stop the app from booting -- a rejected config is logged and skipped, leaving
the previous provider untouched.

Gabe 15ec0bf1c5 fix(printers): use the model-appropriate name in the fan-speed response
The fan-speed endpoint always reported 'Chamber fan set to N%', so on
P2S/X2D — where the printer card labels that fan 'Exhaust' — clicking
Exhaust produced a toast saying Chamber fan.

Adds uses_exhaust_fan_label() to printer_models so the badge label and the
API response share one source of truth, and uses it to pick 'Exhaust fan'
vs 'Chamber fan' in the response message.

Tests: helper coverage for P2S/X2D (incl. internal codes N7/N6), other
enclosed models, and unknown/missing model; API test asserting the message
matches the badge label per model.

Gabe 9ee162d51a feat(printers): expose P2S/X2D accessory fans (left aux + exhaust)
The P2S/X2D have two fans bambuddy didn't fully handle. On the P2S both are
add-on kits; on the X2D they ship from the factory.

1. Left auxiliary part cooling fan — not shown or controllable. It is reported
   ONLY as device.airduct part id 10 (raw id 160 >> 4; FAN_REMOTE_COOLING_1 in
   Bambu Studio's DevFan::ParseV3_0) and is never mirrored into a flat
   big_fanX_speed field, which is why it was invisible. This is the gap
   identified in #2576, where the single 'Auxiliary' fan (big_fan1 / M106 P2)
   only reaches the right-hand aux fan.

2. Chamber exhaust fan — shown on every P2S labelled 'Chamber Fan'. On P2S/X2D
   Bambu's firmware/UI (and Bambu Studio's FAN_CHAMBER_0_IDX) call it 'Exhaust',
   and it is a kit on the P2S rather than built in.

Both are now detected from device.airduct.parts, which lists only the fans that
physically exist, so each tile appears only when the hardware is present.

- bambu_mqtt: parse airduct part 10 -> left_aux_fan_speed (None when absent) and
  part 3 presence -> exhaust_fan_present; set_fan_speed() accepts index 10 plus a
  set_left_aux_fan() helper
- schema / status route / printer_manager broadcast / mqtt_relay expose both fields
- POST /printers/{id}/fan-speed accepts fan=aux2 -> M106 P10, the command Bambu's
  official P2S machine profiles use
- frontend: 'Left Auxiliary Fan' tile shown when reported; big_fan2 tile labelled
  'Exhaust' and presence-gated on P2S/X2D, unchanged 'Chamber Fan' elsewhere
- i18n: leftAuxiliary + exhaust for all 12 locales

Verified fan -> field map on a live P2S (fw 01.02.00.00), stable across cooling
and heating airduct modes:
  Part cooling -> cooling_fan_speed / airduct id 1  (built in)
  Aux          -> big_fan1_speed    / airduct id 2  (built in)
  Exhaust      -> big_fan2_speed    / airduct id 3  (kit)
  Left aux     -> airduct id 10 only (kit; forced off in heating by mode config)

Tests: airduct id-10 parsing (raw 160 -> id 10, not literal 160), id-3 presence,
base-P2S absence, diff-push survival, clamping, malformed entries, M106 P10
emission, invalid-index rejection; fan-speed API aux2->10 mapping; frontend tile
presence and labelling per model/kit.

maziggy 9d549050f7 fix(cloud): complete the CSRF handshake on Bambu Cloud TOTP sign-in (#2696)
Signing in to Bambu Cloud with an authenticator-app account failed every
time with "Invalid code", whatever the code was. Bambu Lab added double-
submit CSRF protection to the bambulab.com web origin - which is where,
and only where, this service posts the two-factor code. The endpoint
refused the request with 403 "CSRF error: missing_cookie" before it ever
evaluated the code, and Bambuddy reported that refusal as a bad code.

Verified against the live endpoint with a deliberately invalid key: a
bare POST returns missing_cookie; GET /api/csrf mints a bbl_csrf_token
cookie; a POST carrying only the cookie returns missing_header; a POST
carrying the cookie plus an x-bbl-csrf-token header reaches application
logic. Landing on the sign-in page first - the intuitive fix - does not
help, as that page sets only Cloudflare's __cf_bm. Of five header
spellings tried, only x-bbl-csrf-token is accepted, so the tests pin it.

verify_totp now performs that handshake against the same origin it will
post to (bambulab.cn for the China region - a token minted by the global
site is a cookie the .cn endpoint never issued), and declines to submit
the code at all when no token can be obtained rather than burning the
user's 30-second TOTP window on a request that is certain to be refused.
A CSRF refusal now also says the code was never checked instead of
masquerading as a wrong code, which is what sent the reporter chasing
clock drift and leading-zero parsing.

Only TOTP sign-ins were affected. Every other cloud call, the email-code
two-factor path included, goes to api.bambulab.com, which is not gated,
and existing stored tokens were unaffected throughout.

The region-routing test's MockTransport needed teaching about the
handshake: it returns one canned response for every request and set no
cookie, so the fix correctly refused to POST and the test lost the URL it
asserts on. It now mints a token for /api/csrf and additionally checks
the handshake stays on the .cn origin.

maziggy 8551e32f14 feat(slicer): keep the designer's print settings when re-slicing for another printer (#2622)
Published models often deviate from the stock Bambu profile on purpose -
five walls, 100% infill, a 0.1mm first layer. Re-slicing one for a
different printer discarded all of it: the picked process preset
overrides the file's embedded settings, and that override is precisely
what makes cross-printer re-slicing work, so it cannot just be dropped.
"Slice as designed" (#2611) does not help - it is all-or-nothing and
only offered when the picked printer already matches the design's
target.

The deviation list does not have to be computed. Bambu Studio writes it
into the 3MF as different_settings_to_system, laid out as
[process, *filaments, printer] - verified against real files at 2, 3 and
4 filament slots. The parser refuses any file whose array length
contradicts its own filament count rather than guessing an index, since
reading the printer slot as the process slot would carry the designer's
machine_start_gcode onto a foreign printer.

The slice dialog now lists exactly which print settings the author
changed and what each was set to, with a checkbox per setting. Design
intent - wall count, infill, layer and first-layer height, supports,
seam, brim, ironing - is ticked by default. Printer-specific values -
speeds, accelerations, jerk, fans, temperatures, prime-tower geometry -
are listed with a badge but start unticked: tuned for the author's
machine, they can be merely wrong on the target or outside the range its
profile accepts, which fails the slice outright.

Only ticked keys are sent, and only keys the source actually flags as
changed are applied. Values are written into the outgoing process JSON,
the same mechanism the support carry-over has used since #1881: for a
Standard preset pick that JSON is an inherits stub, so the patch is the
child in the chain and wins over the flattened parent. Process slot
only - filament picks are honoured as chosen.

The wiki's "this is not a settings merge" note under Slice as designed
described the gap this closes; rewritten to point at the new panel.

maziggy 8fd1f884dc feat(mqtt): publish the plate-clear gate and add a notification for it (#2525)
When a print reaches a terminal state Bambuddy holds the queue until
someone confirms the build plate is clear. That gate was visible only in
the Web UI: the printer's own MQTT push reports nothing beyond RUNNING,
PAUSE, FAILED, FINISH and IDLE, so an external automation could not tell
"finished" from "finished and still waiting for a human".

The per-printer status topic now carries an awaiting_plate_clear field,
and every transition is additionally published on a new retained topic,
bambuddy/printers/{serial}/plate_clear. Retained, and published from the
flag itself rather than from printer telemetry: a subscriber learns the
state of every printer the moment it connects, and the state stays
correct after Auto Off powers a printer down - telemetry stops there,
which would otherwise leave the status topic frozen at false.

Publishing is edge-triggered. The queue clears the gate on every
dispatch whether or not it was up, and no subscriber should see a
"plate cleared" for a plate that was never dirty. Persistence and the
WebSocket broadcast stay unconditional; they are idempotent and predate
this.

A matching Plate Clear Required notification event was added, off by
default on every provider because it fires after every print at the
same moment as the print-complete alert. Only the rising edge notifies.
Acknowledging still goes through POST /printers/{id}/clear-plate.

Two tests in test_printer_manager_status_broadcast.py asserted
_schedule_async.call_count == 2 for the setter. The new emission makes
it three on a transition, so they now assert that the persist and
broadcast coroutines are actually scheduled - which is the contract

maziggy af7874546a feat(projects): per-file print progress and complete-sets tracking (#1897)
Projects made of many distinct files that each need N prints (e.g. 13
plates x 10 sets = 130 prints) only had aggregate progress. Finding out
"how many times have I printed plate_7?" meant reading the Activity
Timeline line by line, unusable at 130 events.

Projects now take an optional Copies per File target. Every printable
file in the project's linked folders shows an X / N badge with a mini
progress bar (gray not started, amber in progress, green done), and the
progress card gains a Complete Sets bar - the minimum per-file count,
i.e. how many finished assemblies can be shipped right now. Without the
target, printable files show a plain printed-count badge.

Counting matches the aggregate project stats: completed runs only,
served by a new /projects/{id}/file-progress endpoint. Runs attribute
to a file via a new library_file_id stamp on queue-dispatched archives,
falling back to content hash and then filename for historical rows.

Also fixed: files queued from a project-linked File Manager folder now
inherit that project, so their prints count toward project statistics -
previously only prints started from the project page were attributed.

Test-harness fix along the way: the test suite's get_db override never
committed, unlike production get_db, so endpoints relying on the
request-scoped commit silently lost their writes in tests. The override
now mirrors production commit/rollback semantics.

maziggy 1fb6978ee1 feat(library): let users delete empty folders (#1781)
Library folders have no ownership tracking, so folder deletion was
gated entirely behind library:delete_all - a user with
library:delete_own could create folders and delete their own files,
but the emptied folder sat there until an admin removed it.

Users with library:delete_own can now delete folders that are truly
empty: no subfolders and no files, including trashed ones - folder
deletion cascades, so removing a folder that holds another user's
trashed file would silently break trash restore. External folders
(operator-configured mounts) and folders linked to a project or
archive still require library:delete_all even when empty, since
deleting them affects more than the folder itself. The bulk-delete
endpoint applies the same rule instead of skipping all folders for
non-admin users.

The folder tree's Delete entry enables accordingly and shows a
"You can only delete empty folders" hint on non-empty folders. The
backend stays authoritative - a folder that only contains trashed
files is invisible in the tree but still refuses deletion.

maziggy eae5359fbc feat(printers): show AI failure detection state on printer cards (#1546)
The live Obico classification was only visible under Settings ->
Failure Detection, so tracking how detection matched an ongoing print
meant flipping between the Printers screen and Settings.

Each printer card's badge row now shows an AI badge whenever detection
is enabled for that printer, like the other health badges: gray Idle
while no print is being watched, then green Safe, amber Warning, or
red Failure while a print is actively monitored. The tooltip carries
the current smoothed score; clicking jumps to the full detection
status and history in Settings. Printers excluded from the monitored
subset show no badge.

Served by a new lightweight /obico/printer-status endpoint readable
with printer permissions alone - it exposes only the enabled flag, the
monitored-printer set, and per-printer classification, keeping ML URL
and other configuration behind the existing settings-gated endpoint.

maziggy d68724c689 feat(stats): energy usage in cost records and trends (#1432)
The Most Expensive record on the Statistics page ranked prints by
filament cost alone, ignoring the per-print energy cost Bambuddy
already measures via an attached smart plug. It now ranks by
filament + measured energy cost; prints without smart-plug data
compete on filament cost alone, as before.

Filament Trends gains an Energy Over Time chart: kWh per day (per
hour for ranges of a week or less, per week for long ranges), with
the range's total kWh and energy cost in the header. The chart only
renders when the selected range contains measured energy data, so
setups without smart plugs see no change.

The /archives/slim stats feed now carries each run's energy_kwh /
energy_cost from print_log_entries. Translated in all locales.

maziggy 8646c40957 fix(slicer): reject invalid sidecar output instead of storing a corrupt slice (#2671)
The slice client only checked the sidecar's HTTP status, not its body. When the
sidecar -- or a reverse proxy in front of it -- returned 200 OK with a body that
wasn't a real 3MF (a stock/misconfigured sidecar, a proxy error page, a truncated
response, or an OrcaSlicer/Bambu Studio CLI crash emitting no output), Bambuddy
wrote that tiny blob to a .gcode.3mf, stored it as a valid sliced file (the
3MF-parse failure was swallowed as "no thumbnail"), and let it be queued and FTP'd
to the printer -- producing the ~28-byte files that "did nothing" and then failed
at print time. Separately, a genuine 413 comes from the proxy in front of the
sidecar rejecting the multi-MB upload (model + profiles), so raising the body
limit on the wrong proxy layer had no effect.

- Factor the duplicated status handling in slice_with_profiles /
  slice_without_profiles into one _handle_slice_response.
- When a 3MF export was requested, validate the body is a real ZIP; otherwise
  raise SlicerApiServerError with an actionable message instead of persisting
  a corrupt file.
- Special-case 413 with a message naming client_max_body_size on the proxy
  directly in front of the sidecar (Cloudflare cap noted).

maziggy 1bdd7d224a fix(library): sort File Manager by real filesystem mtime, recursively (#2680)
The folder tree's "sort by recent activity" and the file pane's date sort
put external (mapped/NAS) files in a near-random order instead of ls -t's
newest-first. Nothing captured the files' on-disk mtime: the sort keyed off
the DB updated_at/created_at, which for a bulk external scan is the same
scan instant for every row, so a whole block tied and sorted arbitrarily;
only rows Bambuddy had later touched individually looked "partially right."
The tree also bubbled up only immediate child-file activity, so a file added
deep in a subtree never lifted its parent folders.

- Add nullable fs_modified_at to LibraryFile and LibraryFolder (dialect-
  branched migration, mirroring the #2615 dispatching_at pattern).
- External scan records each file's and directory's real os.stat().st_mtime
  and refreshes it on every re-scan, so a file edited over the mount
  re-sorts and existing installs backfill on the next scan.
- list_folders computes each folder's activity as a recursive newest-
  descendant roll-up (post-order), so a fresh deep file lifts every ancestor.
- Folder tree sort and the file pane's date sort now use the real mtime,
  falling back to created_at for managed uploads with none.
- New toolbar toggle shows/hides each item's last-modified date in the right
  pane (grid + list), with strings in all locales.

Store the mtime as naive UTC to match the other timestamp columns so activity
comparisons never mix naive and aware values on either dialect. Covered by
integration tests (mtime capture, re-scan refresh, deep-file recursive bubble,
folder mtime) and a frontend test proving fs_modified_at is preferred over
created_at.

maziggy 41ad1d65c7 feat(skip-objects): select items directly on the build plate
Pairs the top-down plate preview with the slicer's per-object pick mask
(Metadata/pick_N.png), whose pixel colours encode the same identify_id the
firmware's skip command takes, so a click resolves to a real object rather
than an inferred bounding box. Several objects can be selected before one
confirmation; selected and already-skipped items are highlighted on the
plate; the checklist stays available when no mask exists.

view=pick serves only the active plate's mask and 404s otherwise, unlike
every other view. A render returned in a mask's place would be decoded as
object IDs — dark pixels yield small integers that collide with real ones —
and a click would then skip an arbitrary object, mid-print, irreversibly.
The 404 is what tells the UI to fall back to the checklist.

Click mapping goes through the contained rect, since the canvas paints at
mask resolution under object-contain; clicks on a letterbox bar are rejected
rather than clamped onto whichever object touches the border. Confirming
names the object when one is selected and counts them when several are,
which is what plates of identically-named clones need.

No printer-control command path was added or changed; the layer, permission
and existing skip-command guards are untouched.

maziggy 2e45893dd5 feat(print-options): add "Auto" state to bed levelling, flow & nozzle-offset calibration
Bed levelling, flow calibration, and nozzle-offset calibration were on/off
only, so the sole way to run bed levelling was to force a full level before
every print. Bambu Studio has always offered a third "Auto" state that lets
the printer skip the calibration when it was done recently -- the state most
users actually want. Make these three options tri-state (off/on/auto),
defaulting to auto, and leave vibration/layer-inspect/timelapse as on/off
(Bambu Studio exposes no auto for those).

Wire encoding follows Bambu Studio's source exactly: each option sends a JSON
bool (true only for "on") plus a companion int -- off=0, on=1, auto=2. The
bool fields stay booleans (the #1478 H2S regression); only the companion int
widened from {0,1} to {0,1,2}. #1721's observation that stage 8/39 stays
queued when sending 2 is the auto contract (queued, skipped at runtime if
recent), not a broken "off".

- schemas: TriState = Literal[off/on/auto] with a BeforeValidator coercing
  legacy bool / 0-1 / true-false so old clients and un-migrated rows validate
- model + migration: boolean columns -> String; SQLite via column affinity +
  data backfill, PostgreSQL via ALTER COLUMN TYPE guarded on information_schema
  (verified on both dialects); settings rows normalised true/false -> on/off
- MQTT: start_print takes the tri-state strings and emits the paired bool+int
- Virtual Printer: reconstructs the slicer's auto/on/off from the int companion
  (auto_bed_leveling / extrude_cali_flag) in both capture paths
- frontend: CalibrationMode type; off/auto/on segmented controls in the print
  dialog, queue bulk-edit, and Settings -> Workflow; calibrationMode_* strings
  in all 11 locales

maziggy 258db95483 fix(overlay): authenticate the OBS overlay with a token when login is enabled (#2613)
The /overlay/{id} route renders without a login, but everything it draws is
auth-gated: printer status and name (PRINTERS_READ), one setting (SETTINGS_READ),
and the camera stream (a camera-stream token). A signed-in browser rides its JWT
from local storage; OBS is a fresh browser with no session, so the overlay stayed
blank whenever authentication was enabled. Cloudflare/remote access was never the
cause -- an incognito window fails identically.

Give the overlay a self-contained kiosk-token mode, mirroring the Cam Wall:

- New `overlay` long-lived-token scope, kept separate from `camwall`: the overlay
  names the printed file on screen, which a Cam Wall token is trusted never to
  expose, so folding it in would silently widen every existing wall token.
- New token-authed GET /printers/{id}/overlay-status returning exactly the fields
  the overlay draws and nothing else; added to the auth-middleware allowlist so it
  reaches its own RequireOverlayTokenIfAuthEnabled gate.
- StreamOverlayPage reads ?token= and, in that mode, authenticates its status and
  camera calls with the token and skips the WebSocket (the 2s poll is the feed).
  The logged-in path is unchanged.
- Token-mint UI (Settings > API Keys) offers the scope with a ready-made
  /overlay/{id}?token= URL copied once on creation.

maziggy 64f9d04c80 fix(queue): claim a queue item before dispatch so it can't be reassigned mid-upload (#2615)
A queue row stays status='pending' for the whole FTP upload; status only flips
to 'printing' at the end. The edit routes only blocked non-pending rows, so a
PATCH during the upload window was accepted while the in-flight dispatch kept
using its snapshotted printer -- splitting the queue row from the archive /
expected-print / physical command across two printers, and enabling a duplicate
dispatch on restart. The #1853 CAS guards cancellation, not reassignment.

Add a dispatching_at claim, stamped atomically (WHERE status='pending' AND
dispatching_at IS NULL) before any slow I/O and cleared on every exit. While
held, the single-item PATCH returns 409 (re-checked just before the write),
bulk edits skip the row, and the scheduler won't re-select it. Startup
reconciliation clears claims orphaned by a crash mid-dispatch. The row stays
pending throughout, so no status/UI/completion/reconciliation path changes.

New column print_queue.dispatching_at (nullable, dialect-safe DDL). Covered by
scheduler tests (claim exclusivity, non-pending rejection, release-on-exit,
skip-already-claimed, startup stale-clear) and API tests (reassign 409,
printer_id unchanged, bulk skip, unclaimed row still edits).
