D12 had been OPEN since the 2026-08-08 calibration, and D3 said it
depended on D12. In the meantime the milestone D3 named was delivered
and closed on 2026-08-30 and the application reached 0.12.2 with every
cluster the calibration selected at least begun. The decision the
register was waiting for had been made by building, so the register
now says so: full scope stands, v1 has no date, and "post-v1" in §7 is
the one way a clause leaves the count.
The status line also stops calling this a draft from August; it has
carried eleven dated amendments since.
The sweep fetches the whole original before it can learn anything
about it, and the one file in the reference library the decoder
refuses on sight is a 521 MB stitched panorama — so every pass on the
tablet spent half a gigabyte of Wi-Fi to find that out again. The
catalog already knows the byte count, and that is enough to decide
before the fetch: originals over 256 MB are marked examined with
nothing found and a zero edge, counted as failed, and named in the
log. Below the line is every camera RAW the library holds; above it,
four files, all panoramas.
A budget and not a verdict on panoramas. The right treatment for one
is a tiled pass — read it in strips, detect in each, stitch the boxes
back — and the zero edge is what that pass would select on. Until it
exists, this is what keeps a background sweep on a phone from paying
for the decision the decoder cannot make.
Rating and flagging were reachable from the grid alone, so a photograph
opened in develop could not be judged without leaving it; FR-UI-5 said
"rating" without qualifying the view and was built as though it had.
And FR-UI-1's expanded row has said "filmstrip" since it was written
while the roll stayed on demand in both classes. Both are amended to
say what they meant: judgement follows the photograph, without
auto-advance outside the culling mode, and the roll is open by default
where there is room for it.
The larger change is a rule. Per-face signals — eye state from a
classifier, head pose from the five landmarks the detector already
yields — are worth having for culling, and §3.9.1 excluded detecting a
blink outright. The exclusion was always of judgement, not of knowing:
a blink is a fact about a frame of the same kind as a clipped
highlight. FR-CULL-8a specifies the two signals; FR-CULL-13 says what
any signal may do (be shown, filtered, sorted, propose a burst
representative) and what none may (write a rating or flag without a
user action between). R7 states the same thing as a user need.
Licensing was read before either was written. OCEC's eye-state weights
are MIT with a clean data chain; every open gaze model is trained on
Gaze360 or its peers, whose licences restrict derived models by name,
so gaze is deferred in §7 and head pose stands in for it. D13 records
both so they are not re-searched.
Replacing a closed-eyed face from a neighbouring frame was raised and
is written down as D17 rather than built: it is the multi-source schema
question §7 already defers for panorama and HDR, with its non-goals —
never automatic, provenance declared — fixed now.
Traceability regenerated: three new IDs, none yet tagged.
Choosing "Thorough" made the library look empty. The detector setting
writes under its own faces.model_id, and every reader of "the faces"
keyed on that exact id: the clustering pass, the coverage figure, the
sweep's work list, the shard export and import, and the sync merge's
face matching. On the reference library that restarted coverage at
1,834 of 19,140, drew a People rail of 36 faces for a person with 520,
queued a ~400 GB re-fetch on each device, and stranded the desktop's
3,583 confirmations under the old id: the tablet held the same faces
under the new one and the merge refused to match them. Same photograph,
same box, same embedder, two ids — that is one face, not two libraries.
The embedder half of the id is now the key. embedder_of and embedder_sql
give it to every query; writes keep the full id, so which detector drew
a box stays on record. record_detections is unchanged and is where the
generations meet: an image holds one pipeline's faces at a time, and a
re-detection carries confirmations across by box overlap. The merge's
match_faces applies the same rule within an embedder. The calibration
is keyed on the embedder too, since the similarity space did not change.
Shards travel every generation, each under its own id, and a peer adopts
whichever it is sent — including a stronger detector's pass over an
image it indexed itself with a weaker one, which is the re-detection its
own sweep would otherwise queue, already done. Never downwards: a tablet
on Fast keeps the desktop's Thorough faces. The sweep gains the same
tail — images a weaker detector indexed, after the ones nothing has —
driven by FaceDetector::supersedes, so choosing a stronger detector still
improves the library over time without first making it disappear.
A decode failure in the face sweep was counted, logged at debug where
nobody saw it, and left unmarked — so the next pass fetched the same
file and failed the same way. For the 521 MB panorama behind rawler's
panic that was half a gigabyte per sweep, on a tablet. It is now marked
examined with nothing found and a zero edge, which is what a later "try
again with a better decoder" pass would select on, and the warning
names the file. The failure count is unchanged: it did fail.
rawler panics on some input rather than returning Err — a DNG whose IFD
claims a >50000 px image, which the reference library has: a 521 MB
stitched panorama, IMG_4181-Pano.dng. On a worker thread a panic is the
end of the thread, so the face sweep that met it stopped thirteen
seconds in, three sweeps running on the tablet and three on the
desktop, with "17301 image(s) to index" as the last word. FR-RAW-4
says a malformed file must not abort a batch, and that is this crate's
promise whatever the library beneath it does: every entry point that
calls into rawler now runs under catch_unwind, and a file that panics
the decoder is one failed file with the panic's message in the error.
Verified on the panorama itself: metadata reads, decode returns the
error, the thread survives. The crash hook still records the panic,
which is right — it is a defect in a dependency and the record is how
it gets reported.
Walking the photo roll was one download per frame: every step showed
"Downloading…" over an empty canvas while tens of megabytes came down,
and moving between a pair of near-identical frames paid that a dozen
times. Now, once the opened photograph has landed, the ones around it
are fetched into the originals cache while it is being looked at, so
the next step is a disk read.
A single worker serves the latest wish only, closest first and working
outwards — next, previous, next-but-one, previous-but-one… — one file
at a time. Each open replaces the wish, so a fast walk never leaves a
trail of stale downloads competing with the one being waited on. A
process-wide in-flight registry makes a click on a photograph that is
still being fetched ahead wait for that transfer and read it from disk,
rather than start a second download of the same file.
How far each side is a setting under STORAGE — Off, 2, 5, 10 or 20,
defaulting to 5 — and it is moot while "keep originals after opening"
is off, since a fetch the cache would discard on arrival is transfer
for nothing. Nothing is fetched ahead while offline. The transfers show
in the activity list while they run and are removed when they end.
The launcher and the task bar have shown a generic tile for a working
window since the call was written. set_xdg_app_id sat at the top of
run(), on the reasoning that the app id is read when the surface is
created — true, and beside the point: the call goes through Slint's
global context, and there is no global context until something installs
a platform. That is BackendSelector inside shared_gpu, or AppWindow::new
falling back to the default, and both happen further down. Called before
either, it returned NoPlatform and did nothing at all.
It moves to just after the window is constructed, which is not the same
as shown — run() is far below — so there is a platform to talk to and
the surface does not exist yet.
The failure was logged at debug, which is why a year of grey squares went
unremarked: the whole symptom is invisible from inside the application.
It is a warning now, naming the consequence.
SQLite's busy timeout defaults to zero, and nothing ever set one: the
loser of a write race got SQLITE_BUSY at the moment it asked. WAL does
not cover this — it makes one writer and many readers free, and this
application constantly has two writers, the face sweep committing a
batch while the derived sync imports shards or reclustering reads.
The cost was not a retry but lost work. A sweep that had already paid
for the detection and the embedding — seconds per image, the expensive
part — discarded the result on "storing faces for 214: database is
locked" and moved on to the next image. Both the desktop and the tablet
logged runs of those on consecutive images, which is a face sweep
quietly failing to store the faces it had just computed.
Ten seconds, on every connection, set in configure() so that nothing
can open the catalog without it — the figure the job runner's own tests
have used for this reason since they were written. It is far longer
than any transaction here, so it bounds pathology rather than making
anyone wait.
The first CI run of the Windows leg passed every step up to packaging
and died in makensis with LicenseData: open failed
"target-windows/installer/stage\LICENSE". CI sets CARGO_TARGET_DIR to
the relative target-windows, and NSIS on a POSIX host translates the
backslash in a File path only when a leading / tells it the path is a
POSIX one; a relative name reaches it with the backslash intact.
Locally the target was always /work/…, which is why it never showed.
package.sh now resolves its directories with realpath first.
It also removes any installer already in the output directory before
writing the new one. That directory is cached between runs, so after a
version bump a glob over it finds two, and the smoke test hands Wine
both names joined by a newline as one path — which is what happened
locally the moment the version moved to 0.12.1.
fix/corrupt-remote-catalog-deadlock. The catalog on the server had been
malformed since 7 September and every device declined to overwrite it,
so collections and people stopped syncing everywhere at once; the
damage came from two devices assembling chunks in one upload directory.
Each chunked upload now has its own directory, the server keeps three
generations of the catalog behind the current one, every push is
verified before and after, a damaged copy that arrived whole is merged
from the generation before it rather than pinned in place, and the
catalog is backed up daily as NFR-R2 always asked.
NFR-R2 asks for the catalog to be backed up on a schedule and before
schema migrations. Only the second half existed: every backup on disk
was a pre-migration copy, and a library that never migrated was never
backed up at all.
A backup is now also taken at the end of a library sweep when the newest
one is more than a day old — the moment the catalog is quiet and a day's
collection and people edits have just been folded in — on its own
thread and its own connection, so the copy of a 130 MB file is not spent
on the UI. Whether one is due is read from the backup directory, not
the catalog, so the ordinary case costs nothing. An empty catalog is
skipped: there is nothing in it a rescan would not rebuild. Pruning to
KEEP_BACKUPS applies as before.
Two checks around the upload, both cheap next to what they prevent.
Before: the snapshot is quick_checked before it leaves. It is the copy
every other device merges from, and a damaged one costs each of them a
download, a failed merge and a refusal to push.
After: the staged upload's size on the server is compared to the bytes
sent before it is rotated into place. A chunked upload is assembled
server-side, and an assembly that goes wrong is a file of plausible
size no device can open — caught here, on the device that caused it,
for one listing; otherwise on every other device, after the fact. A
mismatch, or a size the server will not confirm, discards the upload
and leaves the current copy and its generations untouched.
The server held one copy of the catalog, overwritten in place on every
push. When that copy was damaged there were two answers, both bad:
refuse to touch it for ever, which is what every device did for a week,
or overwrite it with ours, which loses whatever another device had
added since — the escape hatch of the previous commit.
A push now uploads to catalog.upload.sqlite, rotates catalog.sqlite to
.1 (and .1 to .2, .2 to .3, dropping the oldest), and moves the upload
into place. Rotation is server-side renames, oldest first so that every
destination is empty when it is written to — move_to refuses to
overwrite, by design — and a failure at any step leaves a gap in the
generations and never a missing current copy. The only transfer is the
upload itself.
A damaged current copy that arrived whole now merges from the newest
readable generation before ours goes over it, which loses nothing, and
is kept as .1 by the ordinary rotation rather than by a separate 40 MB
upload. NFR-R2 asks for the catalog to be backed up; this is the half
of it that lives with the copy other devices read.
The upload directory was named from the destination path alone, on the
reasoning that two files could then not collide. Two devices uploading
the same file could, and did: both wrote 00001…00009 into one directory,
and whichever MOVEd first assembled a mix of the two — a catalog of
exactly the right size whose pages came from two different databases.
SQLite called it malformed, every client declined to overwrite it, and
collections stopped syncing on all of them for a week. A transfer that
died on a phone's link left its chunks there for the next device to
assemble in, by the same mechanism.
The name now carries a nonce as well, so no two uploads share a
directory, and a failed transfer deletes its own directory on the way
out rather than leaving 5 MB chunks for the server to sweep eventually.
"The chosen detector is not installed" was the whole of what a user
saw, on a machine where the files were three directories away from
where the lookup went. The search order was in a doc comment and
nowhere a user could read it. Now a missing pair logs the detector
file it wanted and every directory it tried, which is what the first
Windows install needed and what the next misplaced download will.
SettingsStore::open read XDG_CONFIG_HOME and HOME itself. Neither
exists on Android, so it resolved to .config/darkroom relative to a
working directory of /, and every settings edit on the tablet failed
with "read-only file system" — the page reported the error and nothing
said why. The doc comment claimed "the same resolution SessionStore
does"; now it is, by calling the same function, which honours the
directory android_main declares and takes the platform's config
directory everywhere else. settings.json sits beside sessions.json on
every platform, as the comment always said it did.
The catalog sync refuses to upload when it cannot read the server's copy,
because the upload is a read-modify-write and writing blind would discard
another device's collections. That is the right rule for a timeout, a
dropped connection or a newer schema — the remote is fine, only our view
of it failed.
A file SQLite calls malformed is not that. No device will ever read it
again, so refusing to write over it preserves nothing — and every client
declines in turn, pinning the damaged file in place for good. Collections
and people then stop crossing between devices on all of them at once,
each logging "catalog not pushed" on every pass. This library did exactly
that from 2026-09-07, on the desktop and on a freshly installed phone
alike, while 32 collections sat undelivered.
Now a copy that arrived whole and still will not open is set aside under
a dated name and replaced by ours. Whole is checked against the size the
server advertises: a truncated download will not open either, and on a
phone that is the far likelier story, so anything short — or any size the
listing cannot confirm — is treated as the transport failure it is and
the server's copy is left alone. A placeholder's size is not trusted for
the comparison, since it means nothing.
The report says when this happened, and the log line calls it "pushed
over a damaged copy" rather than folding it into an ordinary push: it is
the one push that discarded something.
The fourth leg of build-and-test.yml, in the shape of the Android one:
an image workflow that builds docker/windows and pushes it tagged by
the directory's tree id, and a job inside that image that lints the
Windows target — the only place the cfg(windows) branches are ever
compiled by CI — builds, runs the smoke tests docs/windows.md §6
specifies, packages, installs and uninstalls under Wine, and uploads
the installer. Every step was run by hand in the same container first.
The spec's open list closes with this: the four §3.2 items, the
licence page, and the leg. What remains is what Wine cannot show, and
§10 now lists it as the first real Windows run's checklist.
The repository declared GPL-3.0-or-later and carried no copy of it;
the Arch package pointed at the system's shared text and nothing else
needed one. The installer does: a licence page needs a file to show,
and the moment before installation is where the terms can still change
a decision. The standard text, at the root where every convention
looks for it, converted to CRLF at packaging time because a Windows
edit control draws a bare LF as nothing.
Login Flow v2 cannot complete without a browser, and the launcher had
a branch for xdg-open, one for Android's Intent, and an honest
Unsupported error for everything else — which on Windows stranded the
flow on "approve the sign-in in your browser". rundll32
url.dll,FileProtocolHandler is ShellExecute on the URL and needs no
crate; chosen over cmd /C start, whose quoting of & in a query string
is a known trap. Not verified: Wine has no browser to open.
The Secret Service store was keyring::Entry all the way down, and
keyring 4's v1 feature set — the one the workspace already asks for —
includes the Windows Credential Manager backend. So the Windows store
is the same implementation with its cfg widened, and the crate as a
target dependency. The one behavioural difference is that the
availability probe always succeeds there, which is correct: Credential
Manager is always present, so FR-NC-2's degraded mode does not arise.
Until now a Windows build compiled, started, and failed at sign-in
with the placeholder store's "no secret store is implemented".
Five sites each read XDG_*_HOME and fell back to $HOME/.local/… on
their own, which is fine on Linux and wrong everywhere else: Windows
sets neither variable, so every one of them degraded to a path
relative to the working directory — for a Start Menu launch,
C:\Windows\System32. The models lookup walked XDG_DATA_DIRS the same
way.
dr_plat::dirs now holds the rule per platform: XDG on Unix, the known
folders on Windows — %APPDATA% for config, which roams, and
%LOCALAPPDATA% for data and state, which do not — and the executable's
own directory as the system data dir, which is where the installer
puts the models. The Android overrides stay where they were; only the
fallback behind them moved. Both rule sets are unit-tested on either
host, and the Windows one was confirmed by running the application
under Wine: its log landed in AppData\Local\darkroom\state and nothing
was written anywhere else.
FR-CAT-13 asked for standard XMP and `core/dr-xmp` answered the file: it
has read and written `dc:subject`, `xmp:Rating`, `xmp:Label` and the IPTC
core since 5fa4c07, under an ownership rule that leaves everything else in
the document untouched. What nothing did was call it. No scan found an
`.xmp` beside a raw, no catalog row was filled from one, no judgement
wrote one back, and the "external modification detected, reload offered"
clause had no mechanism. A library imported from Lightroom came in and
could not go back out.
The scan collects `.xmp` beside `.drsc` from the listings it was already
paying for, and the pull reads each one whose ETag has moved. Both
namings resolve: darktable's `IMG_0001.CR3.xmp` names its file exactly,
Lightroom's `IMG_0001.xmp` names the stem, and under the stem the JPEG
beside a RAW is the same photograph and takes the same document, as
DarkRoom's own sidecar already does. Each is reconciled with the catalog
winning — keywords union, a rating or label taken only where the catalog
has none — because a standard XMP carries nothing that could say whether
its value is newer. A genuine disagreement is not resolved; it is written
to a table, and the settings page offers the sidecars' values against it.
That button is the reload the requirement asks to be offered, and the
ETag that moved is the detection it asks for: an `.xmp` edited elsewhere
is exactly a file the pull's ordinary incrementality re-reads.
Writing goes the other way behind a setting that starts off, since NFR-R4
makes writes beside somebody's originals theirs to switch on. With it on,
a judgement or a keyword rewrites the sidecar of whichever spelling
exists, or creates Lightroom's. The record is read from the catalog
whole at that moment rather than carried from the gesture, so a rating
and a keyword a second apart are two writes of one file that agree. And
the file's own title, caption, copyright and hierarchy come through the
rewrite: the catalog has no columns for them, `rewrite` replaces the
owned set wholesale, and a record that said nothing about them would have
deleted them from a Lightroom sidecar on every star.
The rating's two axes cross the format's one field both ways: a
rejection is Adobe's `-1` and stars are stars, and stars arriving on a
rejected frame lift the rejection, since the file said it was worth a
number. An unrated file says nothing and clears nothing, on the rule the
`.drsc` merge keeps. `versions.label` finally has a reader and a writer,
with the code table moved out of the query so the two cannot drift.
FR-DEV-5 asked for named snapshots of an edit state and FR-DEV-7 for a
comparison against a chosen one, and neither existed. The history stack
is per sitting and forgotten with it, on purpose — the gap that mattered
was an automatically saved mis-drag with no way back, and that was closed
first. What was left was the other half: a state the photographer wants
to keep *because* it is worth keeping, which is a different thing from a
step and is not served by making the steps last longer.
A snapshot is an edit state, and an edit state is exactly what a sidecar
version stores, so it is stored as one: a `[version]` block carrying
`snapshot-of = <uuid>`. The parameters, the masks and their parts, the
repairs and the film all arrive through the blocks that already carry
them, a merge keys on the uuid as it does for any version, and a build
that predates the key reads the block as a named version and keeps it —
the right failure. Only the pointer is new. The one reader that has to
know is `default_version`, which must never answer with a snapshot: a
file whose edit is missing is not a file whose edit is one of its saved
moments. The snapshots of an edit are listed by that pointer, oldest
first, the same on every device.
Writing them back removes what this sitting deleted and puts in what it
holds, and leaves standing whatever it never saw — a snapshot the other
device took since the photograph was opened here is not this device's to
remove by not knowing about it. That is the rule the version merge
already keeps, applied one level down, and it is why the save carries
the deleted ids rather than replacing the list wholesale as the masks
are. Each is re-pointed at the uuid the save settled on, because the
default may have been fused onto its canonical identity since the
snapshot was taken.
Restoring is one history step, so undo takes it back whole, as a paste
is. Taking and deleting are not steps: they change nothing about the
photograph, and an undo that removed a snapshot would be undoing a
decision to remember. Holding the eye beside one renders the snapshot
and hands the edit straight back — the same suspension "Before" uses,
against a point the photographer chose rather than the file. Two
sessions on the same photograph get ids that cannot collide, stamped
with the second and a random word, because the merge folds equal ids
into one.
NFR-OPS-1 asks for a diagnostics bundle — the log, the schema version, the
GPU and driver, the app version — "with an explicit preview-and-consent
step before anything leaves the device". The log and the crash records
have existed since August; what did not exist was any way to hand them
over that was not `adb pull` and a knowledge of where the state directory
is, which on the tablet the requirement was written for is nobody.
Nothing here sends anything, and that is the design rather than a gap:
crash.rs already says why a transport built ahead of the consent is the
shape of thing that gets switched on by default. The bundle writes one
text file to a place the user can find, so that they can attach it. That
is the moment it leaves, and it is theirs. So the consent guards the
write, not a send. Preparing gathers everything into memory and shows
what would be written — each section, its size, what was taken out, and
where the file would go — and only the second press puts bytes on disk.
A user who reads the preview and presses the other button has changed
nothing anywhere. The gathered bundle is held between the presses so what
is saved is exactly what was shown, not a second gathering that differs
by whatever was logged while they were reading.
One text file rather than an archive, because a `.txt` opens wherever
the user is sitting and pastes into an issue, and because the preview
can then be the file rather than a summary of it. Every line goes
through the blunter of the two redactions on the way in, whatever the
sink already did to it: the log's own rule keeps paths, since a path
read over `adb` is context, but a file meant to be attached to a public
report by someone who may not read it first is held to the crash
record's rule instead.
The About page's graphics line gains the driver, which the requirement
names and the adapter has always reported. And docs/outstanding.md is
corrected on both OPS requirements: it said crash reporting was a
log::error! hook and NFR-OPS-1 had nothing behind it, and neither had
been true since 2026-08-30.
A layer built from parts was missing the one control a correction most
often wants: seeing what it did. The question a subtracted gradient
raises is whether it took only the sky, and the question a stroke raises
is whether it filled the shoulder — and the only way to ask either was
to remove the part and look, which answered the question and lost the
part. The layer's own ring answers a different question, about the
adjustment, and hiding eight layers to check one correction is not an
A/B anybody performs.
So a part carries `hidden`. It is an edit and a history step, as the
layer's switch is, and it is folded into the render fingerprint because
hiding a part changes the mask as surely as removing it does. Where the
mask is built the shown parts are walked rather than the parts, which
is what makes a hidden base hand the fold to the first part that is
shown — and a revealed layer whose every part is hidden clears its slice
rather than leaving whatever the last rasterisation put there to be
read back. `covers` asks the same shown parts, so a layer whose only
adding part is hidden costs no slice at all.
In the sidecar the key is `hidden`, in the part's block or, for the
base, in the mask block — under a word that cannot be confused with the
layer's `enabled`, which has always meant the layer. Absent means shown,
so no file written before the switch existed reads any differently.
The row wears the same ring the layer does, one row down, because it is
the same question about a smaller thing.
FR-DEV-16's book said resetting a control and hiding a mask layer were
reachable by pointer and by finger, and stopped there. The reason was
honest: the generated rows have no focus, so "reset the focused control"
named a thing the panel could not point at. But a photographer at the
keyboard means something narrower than focus. They mean the slider they
just dragged too far, and that is a thing the panel can remember.
So the Adjustments global keeps the last control moved — two indices,
written where the panel forwards the change and cleared when the next
photograph opens, so a reset cannot reach back into the previous edit
through an index that happens to be shared. R puts it back, through the
same callback the track's double-click takes, and is silent until
something has moved.
The mask layer needs no such notion, because the panel already has a
selection: the rows the edge controls point at. H hides or shows those,
through the path the ring at the head of the row takes, so it is an edit
and a history step exactly as the ring is. A mixed selection goes to
shown, since the layer nobody can see is the one being asked about.
Both tags now carry the key, and the book says so.
docs/windows.md specified it; this is §9 steps 1, 2 and 4 run, and the
report in §10. A Debian trixie image with rustup, the MinGW cross
compiler, NSIS and Wine; a build.sh in the shape of the Android one;
a package.sh that stages the executable and the seven models behind
the same LFS-pointer guard every other packager carries, then runs
makensis; and the .nsi itself — per-user, no elevation, an uninstaller
that leaves the library alone.
Measured: the executable links first time once the link flags were
right, imports only Windows system DLLs, prints its version under
Wine, and the installer installs and uninstalls silently under Wine
with the registry key and the models where §5.2 says. What Wine
cannot show is the Start Menu shortcut: CreateShortcut is IShellLink
and does nothing headless.
Four claims in the spec's first draft were wrong and are corrected in
place with the reasoning kept: the whole-archive winpthread flag
breaks the link and was never needed; build scripts need a host gcc;
bookworm's Wine lacks the bcryptprimitives.dll rustc's std imports,
so the image is trixie; and NSIS's default stub is 32-bit, so the
installer says amd64-unicode and needs no i386 Wine.
Three things the Windows build showed the entry point was missing, and
that a Linux build never asks for.
`--version`, answered before the logger and the crash hook install: a
binary built on a machine that cannot run the application — the Linux
CI producing the Windows executable, checked under Wine — needs an
exit that proves it starts without opening a window or touching the
user's directories. It is the smoke test in docs/windows.md §6.
A GUI-subsystem executable in release, or Windows keeps a console
window open behind the application for the life of the process. Debug
builds keep the console, which is where their log goes.
A resource block, or Explorer, the Start Menu and the taskbar show the
generic executable icon and the Details tab is empty. build.rs wraps
the PNG every other platform uses into an .ico at build time — an ICO
entry may be a PNG, so the wrapper is a 22-byte header — and hands it
to winresource with the version cargo already knows. The crate is an
unconditional build-dependency because a cfg(windows) on one is
evaluated against the host, which here is Linux; the script itself
returns before touching it on any other target.
secrets.rs names the keyring service and desktop_client.rs the socket
timeout, and every use of both sits under a cfg that a Windows build
does not satisfy — the placeholder secret store has nothing to file
under, and the Nextcloud client's named pipe is not opened yet. The
first cross-compile reported both as dead code, which is a failed
clippy job the moment the Windows leg runs with -D warnings. Guarded
by the same cfgs as their users, with the reason beside each.
The tree is closer to Windows than a Linux-only project usually is:
every image library, the TLS stack and the inference engine are pure
Rust, and dr-plat already keeps the Linux-only code behind cfgs with a
loud fallback where none exists for another platform. What remains is
a short list above dr-plat — five XDG path lookups, an xdg-open, the
secret store's third implementation, the models' lookup beside the
executable — and none of it touches core, which is the NFR-PORT-3 test
this would be the first real run of.
docs/windows.md decides the GNU target over MSVC-via-xwin, Vulkan only
as on every other platform, a per-user NSIS installer that leaves the
library alone on uninstall, and a CI leg in the shape of the Android
one. It is explicit about what a runner with no Windows can verify —
that it links, is PE32+, starts under Wine and installs under Wine —
and what it cannot, which is everything involving a real GPU driver.
Three FR-PLAT-WIN requirements and a channel row record the decisions;
the ordering puts a first cross-compile on the developer machine before
any container exists, because the list of cfg gaps is a reading of the
source and the compiler's list will be longer.
The release keystore now exists and its four secrets are loaded into
Gitea, so CI produces an APK a device can update in place. Until now
every build, CI and local alike, was signed with a throwaway debug key
-- CI's fresh per run, the local one exactly as durable as the cache
directory it lived in -- and the night that cache was cleared, no build
anywhere could install over the tablet's copy.
package.sh forwards KEYSTORE_PASS, KEY_PASS and KEY_ALIAS into the
container and copies the keystore under the mounted target directory
for the build, so a local release-signed build is one environment line.
The doc records where the local copy of the key lives.
`a_failed_overwrite_puts_the_original_back` makes the presets directory
read-only and expects the overwrite to fail. CI's Desktop job runs in a
container as root, and root is not refused by a mode: the write succeeds,
the assertion fails, and build-and-test has been red on every push to
master since the test arrived.
The test now probes the refusal it depends on -- one write into the
directory it just locked -- and skips where that write goes through.
Probed rather than keyed on the uid, because what the test needs is the
refusal itself, and a filesystem mounted without permission checks would
pass a uid test and fail this one all the same.
faces.md §12.3 measured what the cheapest detector costs: the small
faces in every group shot, and a dog embedded a dozen times. Which
trade is right depends on the machine doing the sweep — a desktop left
overnight and a tablet on a battery want different answers — so the
detector is now a per-device setting, Fast / Balanced / Thorough on
the settings page beside the indexing button, persisted with the rest
of the settings file.
A detector is half of a model id. Every face, marker, shard and
calibration is keyed on faces.model_id precisely so that a model change
is a new id and a re-index rather than a silent change under existing
data, and a detector change is a model change: it decides which faces
exist and where the landmarks that align them land. So each choice
names its own pipeline. 500M keeps the bare "w600k_mbf" every existing
library was written under, so an upgrade disturbs nothing; the others
are qualified. Choosing one restarts coverage from zero under the new
id, the sweep re-detects, confirmed names carry across by box overlap,
and the sync shards are keyed by the same id so a peer on another
setting neither adopts nor pollutes them. The library controller
carries the id into the sync the same way it carries the cache budget,
because the sync starts from places that have no settings in reach.
All three shape-fixed exports ship — APK, Arch, Flatpak — since a
tablet has no other way to obtain the one it was not installed with;
the APK grows by twenty megabytes for the choice.
record_detections replaces every face on an image whatever model found
them, but left the other models' face_index rows standing. With one
model that was unobservable. With a second pipeline it leaves an image
marked "done" under the first with none of its faces behind the marker
— the state the V12 repair existed to undo — and a user who switched
back would find those photographs permanently empty.
An image now holds the faces of whichever pipeline looked at it last,
and only that pipeline's marker. Confirmed names still carry across by
box overlap, since they were read before the replacement.
§1 chose scrfd_500m on FLOPs and never measured the recall it gave up.
A dr-ui example now runs several detectors over the same sample of
stored proxies, matches boxes by IoU against the first, buckets the
result by face size, times each, and writes contact sheets of the
disagreements in both directions — because a count of extra faces says
nothing until someone has looked at whether they are faces.
Over 400 proxies from the reference library: 2.5G finds 14% more faces
for 12% more time, 10G a further 12% for 3.1× the time. The extras are
small real faces. The 86 faces only 500M found are a dog a dozen times,
a stop sign, a wheel and the backs of heads. Recorded in faces.md §12.3.
CI's Desktop job failed at the Format step on 16f3fb4: rustfmt puts the
`match faces_without_proxy(...)` on its own line under the `let` and
re-indents its arms, and the commit was written without running it. No
code changes; only the layout of that one match in library.rs.
Every face stored before its quality was kept holds a unit vector, and
V14 forgot the run marker of each image holding one so that the next
sweep would look again. Looking again meant detecting again: a whole
re-detection per image, with every suggestion on it thrown away and the
confirmations carried across by box overlap, to recover one number.
The sweep now has a measuring pass between the proxy repair and the
un-indexed images. It lists every image holding an unmeasured face,
fetches the original once, warps each stored face from the landmarks it
already has, embeds it, and writes the raw vector and its length over
the old row. Ids, boxes and identities are untouched; the marker is
re-written fresh so the sync exports the measured vectors. A face whose
landmarks no longer make a warp is dropped, as detection would have
refused to store it. `faces_unindexed` leaves those images to the
measuring pass, so the V14 deletion no longer costs a second detection.
The embedder's raw output has a length, and the length is a reading of
how recognisable the crop was: a blur, an occlusion or a hard profile
comes out short. Normalising threw it away. A short vector sits near
the middle of the sphere and matches a little of everyone, which is how
one bad crop bridges two people in a grouping pass.
So the length is kept — the store now holds the raw vector, re-normalised
on load, with the length beside it as `faces.quality` — and a face under
MIN_GALLERY_QUALITY (14) is a probe: measured against the gallery and
placed where it fits, but never what another face is measured against.
Two probes are never paired, and a probe is nobody's evidence for a
confidence. The People screen shows the number as "Quality 17.3", dimmed
below the floor.
Faces indexed before this stored unit vectors and have no reading; they
are admitted to the gallery, and schema V14 forgets the run marker of
every image holding one so the next indexing pass measures them. A
peer's unmeasured shard faces are not adopted, or a sync would write
that marker back.
The first build of seeing a mask showed the selected layer's, in one global
style, from a strip at the top of the panel. It answered the wrong question and
answered it somewhere nobody looked. What a photographer asks of two masks is
how they meet — where the sky's edge sits against the building's — and that
needs both on screen at once, in colours that can be told apart.
So each row of the stack has an eye, drawn in the colour its mask is shown in,
and each mask has six swatches to choose that colour from. Several can be open
at once; a new one comes up open, in the first colour nothing else is using.
The style — tint, alpha, outline — is the one setting that stays global, above
the stack, because three styles at once are three pictures that cannot be read
against each other. Alpha now draws every shown mask, each in its colour, on
black. In the pipeline a `Reveal` is a list of `(layer, colour)` rather than
one layer, and every reveal block carries its own colour.
The brush moves too. Select, Paint and Erase and the three sliders under them
sat at the top of the panel, appeared only once a row was selected, and said
nothing about which mask they acted on — so "how do I paint" and "how do I
correct the model's outline" both had the same answer and nobody found it.
They sit under the selected mask's parts now, beside the swatches, and on a
subject or a category the hint says what a stroke there does: it becomes a
part of this mask, joined to the model's, and can be taken out again.
Eyes and colours are viewing state, on the session and not on the layer, so a
photograph reopened has every eye closed — the stored-mask round-trip test
asserts it.
Every release commit in the history reads `Release X.Y.Z` and none of them
carries the message this script would have written, so nobody has ever
passed it `--commit` — and the reason is in the message it wrote: a
Co-Authored-By trailer naming an assistant, which no commit in this repository
carries and none should.
The trailer goes, and so does the paragraph above it: the script's own header
already says why it exists, and a release commit is the one place a one-line
subject is the whole convention.
Choosing a category is asking what it selected, and for a subject or a
category that question had no other answer on screen: the model's outline is
not derivable from anything visible, a fresh layer carries no adjustment to
judge it by, and the list it was chosen from says "architecture 23%" without
saying which 23%. The control that draws the mask existed but had to be found
and pressed, a panel's height away from the list the choice was made in.
So a new layer arrives with its mask showing, from the resting position only.
Somebody who has chosen the alpha or the outline keeps it, and nothing re-arms
in the background — every caller is a press that asked for a new mask.
That makes the canvas depend on how a layer arrived, which is correct and
worth stating: a session that has just made a mask draws a frame that a
session which read the same mask out of a sidecar does not. Viewing state is
not edit state and does not travel in a file, and
`a_stored_mask_renders_exactly_what_the_model_rendered` now says so at both
ends.
The brush did nothing, and neither did three other things nobody had tried
lately: clicking a subject on the photograph to select it, placing a repair,
and sampling a neutral. All four are TouchAreas over the canvas, and all four
sat behind the pan/zoom area, which is full-canvas and enabled for everything
but a crop. It took every press in the viewport and they were never offered
one.
Slint hit-tests siblings front-to-back (`send_mouse_event_to_item` visits
children `TraversalOrder::FrontToBack`), a TouchArea answers `GrabMouse` on any
press it is enabled for, and the first grab aborts the traversal. Front means
*last declared*. Each of the four carried a comment saying it sat "above the
pan/zoom area so a click reaches it first" — true of the order they were
written in, and backwards.
Nothing about the geometry decides this, so nothing about the geometry could
have fixed it. The pan area is declared first now, as the backstop it always
meant to be, and the rule it leaves behind is that the general case goes above
the specific ones. `GradientHandles` is the other end of that rule and is why
dragging a handle has worked all along while everything between it and the pan
area did not.
The order is asserted in a test, because this is a fault that compiles, passes
every other test, and silently removes four tools at once.
Every route to a layer began with a selection — a gradient, a band, a subject,
a category — and painting was reachable only by making one of those and
joining a painted part to it. So the answer to "brush a correction onto this
corner of the sky" was "add a radial gradient you do not want, then paint into
that", which is not an answer.
Paint sits beside Linear and Radial and makes a layer whose base is a brush.
It covers nothing until a stroke lands in it, so pressing it arms the brush
and shows the mask as well: a row that appeared and changed no pixel, with the
pointer still in "select", is indistinguishable from a button that did nothing.
Nobody can refine an edge they are not being shown. The only thing drawn on
the canvas was the region overlay — a false-coloured picture of what the model
*detected* — which knows nothing of a layer's feather, its falloff, its
morphology, its invert or its opacity, and nothing at all about a gradient, a
range or a stroke. Every control added for mask editing therefore acted on
something invisible, which is why the whole feature reads as absent rather
than as unfinished.
A layer's finished mask now draws over the photograph in one of three styles:
a tint for whether the right thing is selected, an alpha for where the edge
is, an outline for whether that edge is registered against the detail the
other two hide.
The hard part is not the shader. A selection with no adjustment on it changes
no pixel, so it is not active, so it holds no slice of the mask array and is
never rasterised — and that is exactly the layer somebody wants to look at,
for the whole of the time between choosing a subject and deciding what to do
to it. So `MaskStack::rendered` is `active()` plus the layer being looked at,
and the rasteriser, the composer and the distance-field builder all index by
position in it. Which is also why the design's "two uniforms, no recompile" is
not available: a uniform can select a slot, it cannot conjure one.
The reveal is never on the graph. It reaches the pipeline as an argument to
`compose_revealing`, and `compose_for` — which the exporter, the thumbnail and
the neutral probe all call — has no way to ask for one. A flag on the graph
would have been shorter, would have type-checked, and would have been one
forgotten reset away from a red tint baked into an exported file.
And the tools that shape a mask now arm. `Masking.tool` is an `in` property
only Rust may write, and the handler wrote nothing back, so the strip reported
"Select" however many times Paint was pressed and the paint area was never
enabled — the brush, the parts and the whole of FR-DEV-19b reachable from no
control in the application.
The region overlay stands down while a mask is being shown, and its button now
says what it hides: two overlays that look alike and mean different things is
worse than either.
