dtourolle	78cb00634e	Fetch the photographs around the open one ahead of the step to them ... 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.	2026-09-19 10:36:50 +02:00
dtourolle	896188a489	Read the sidecars other editors write, and write them back on request ... 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.	2026-09-12 01:08:11 +02:00
dtourolle	4f31123b0c	Let the user choose which SCRFD finds their faces ... 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.	2026-09-11 22:12:53 +02:00
dtourolle	0a5eab0487	Wire the develop panels through globals, so a second copy is one line ... Every panel in the develop column declared its inputs and its callbacks and had `app.slint` bind each one to a property or a callback on the window root. That is fine while a panel is drawn once. N9 draws them a second time, in the portrait dock, and the wiring is what would have to be copied: `MaskPanel` alone ran to forty lines of forwarding, and a callback added to one copy and not the other compiles, renders, and simply does nothing on the layout nobody was looking at. So the wiring moved to Slint globals. A panel reads the global and calls the global; Rust hooks the global instead of the window; and the instantiation in the column is now the panel's name and a pair of braces — every one of the ten children of the column, with no property that differs by placement left to supply. There is a global per panel family rather than one for all of them, and the reason is an import cycle. Each panel's model struct — `ParamRow`, `MaskRow`, `HistogramView` — is declared in the panel's own file, so a single global holding `[MaskRow]` and `[ParamRow]` would have to live in a file importing `masks.slint` and `adjust.slint` while both imported the global back, which Slint rejects. Breaking that needs six model declarations relocated, which is a change to the data model and not to the plumbing this is about. A global beside the panel it serves also lets each name drop the prefix it was carrying only because the window root is one flat namespace: `root.spot-radius` is `Repair.radius`, and `root.peaking-on` is `Peaking.showing`. `session.slint` is new and holds the two facts every family needs and none of them owns: whether there is an open photograph to edit, and which mode the view is in, with the three readings of the mode derived once instead of at each of the dozen places that tested one. `ViewMode` moves there from `adjust.slint`, where it was only ever a lodger. Nothing on screen changes. What is not here: the tool rail and the status strip still take their properties at the instantiation, because they are drawn once and N9 does not copy them; the preset sheet's own state stays on the window, because the library grid opens the same sheet and a global cannot bind the window's state — which is why `Transfer.open-presets` is handled in `presets.rs`, beside the summary it already had to compute.	2026-09-07 20:01:01 +02:00
dtourolleandClaude Opus 5	6a97fdf6f9	Put the adjustment groups in the rail where a finger is driving ... Reported from the tablet: the tool rail is very useful there, and the same interface under a mouse and keyboard is not. That is `ui-navigation.md` D-N2's central assumption failing in use, and the interesting part is which half of it failed. D-N2 was right that platform is the wrong axis and width is the wrong axis: a tablet in landscape wants what a desktop wants, and a desktop window dragged narrow wants what a small screen wants. `apply_layout_class` still decides the layout class from the window and nothing here changes that. What D-N2 got wrong is the sentence "touch changes hit regions, not layout" — it identified input as the real difference between the targets and then assumed that difference could never reach the layout. Two controls answer one question — which group of adjustments am I looking at — and neither is better in general. A horizontal strip above the column is one gesture to a target the eye has already found, and it pans when the operation set is rich, so a group can sit off the end with nothing saying so: a pointer user tolerates that, a finger user never discovers it. The same list down the rail is every entry visible at once, each finger-sized, on the edge of the screen the hand is already holding, and it costs no width because the rail is already there. So `ToolRail` grows a second section, and `GroupStrip` stands down when it does. The two are never both on screen, which is why they can share `adjust-tab-picked`: Rust is not told which was pressed and has no reason to want to. Mode and group stay independent axes as N1 requires — one entry lit in each section, and choosing a group while a tool is held still filters without putting the tool down. They stay drawn differently, which N1 also required. The tools fill with `active-dim` and invert their ink; the groups take a bar down the leading edge — the strip's underline turned ninety degrees — so a lit entry says which kind of state it is without the reader having to remember which section it was in. The rule between the sections is the second signal. The rail scrolls now. Its own note argued against a Flickable because "this list is four entries written in this file"; with the groups in it the list comes from the operation set, which is exactly the "something the user's data decides" that note excluded this control from. The axis is input, and it is a preference because the automatic answer is a guess that cannot be made reliable. Neither platform can be asked what the user is holding: an Android tablet in a keyboard case is being driven like a desktop, and a touchscreen laptop is whichever its owner says. `dr_plat::is_touch_first` reports the usual case per platform, and `GroupNavigation` lets it be overridden. Settings names what Automatic resolves to on this device rather than leaving it to be found by pressing. D-N6 records the reversal beside the decision it reverses, including the half that still stands and the question it opens: whether Local is a mode at all, or a scope that would collapse the two sections into one list.

dtourolleandClaude Opus 5	d0b671d4db	Put the grouping dials where the regrouping is ... The merge probability was `dr_face`'s constant and the smallest group was a bare `< 2` in the clustering pass. Both were tuned on one library — 1,813 faces of one photographer's family — and the quantity they optimise is a property of the population, not of the model. A household at close family resemblance and two thousand strangers at a wedding want different answers, and neither of them is the reference library. The doc comment already conceded the point and pointed at `face_index --tune`; a photographer does not have a terminal. So they are `FaceSettings` now, saved per device beside the cache budgets and edited from the People screen — beside the Regroup button that applies them and the rail that shows what they did, because a value changed three screens away from its effect is one nobody can tune. Moving them is safe by construction, which is why nothing asks for confirmation: a regroup writes only the suggested half, and confirmations, names and ignores enter as anchors and come back unchanged. The smallest-group rule is applied only to groups the system invented — a group the user named or set aside survives it whatever its size, because a display preference does not overrule a judgement. **Withdrawal, without which the setting does nothing visible.** Raising the smallest group stops the pass creating small groups; it does not remove the ones a previous pass made, because those still hold their suggestions, so they are not empty, so the prune leaves them. The pass now releases every unanchored face it did not place before pruning. And a dial you cannot see the effect of is not a dial. "What would this do?" runs the same population through the clusterer without opening a transaction and reports groups, faces grouped and largest group — one row of `--tune`'s table, on the user's own library, on a worker thread. The line leads with the group count because that is the number that says which side of the right setting you are on: it climbs as fragments are gathered into people and falls as separate people start being welded, while the grouped-face count rises straight through both. The preview parks its poll timer in a slot of its own. A preview and a regroup are allowed to be in flight together, and sharing the sweep's single slot would have the second to start drop the first's timer — visible as a Regroup that finished on its worker and never said so.

dtourolleandClaude Opus 5	bb35665bd2	Let a paste carry some kinds of edit and not others ... FR-DEV-6 asks for presets "covering a subset of the edit graph". What landed with the named presets covered two subsets: everything, and everything but the crop. "Match the colour but not the sharpening" had no way to be said. `Scope` is now a set of `Attribute` — the same six kinds every operation already declares and the develop panel already builds its tabs from. The photographer ticking "tone and colour" is naming the groups they navigate by, and neither this module nor the interface has to name an operation to do it (FR-DEV-3c). The pleasing part is what left. Framing used to be excluded by an explicit test against one operation's id; it is now excluded because Geometry is not in the default set. The special case dissolved into the general rule, and the argument for it — a crop is a decision about *this* photograph, and carrying it across forty destroys forty compositions — is now a statement about a kind of edit rather than about a node. All thirty-three existing preset tests pass unchanged, which is the evidence that the generalisation kept its promises. One decision that is a field rather than a rule, because the two cases genuinely differ. An operation this build cannot classify — from a newer version, arriving over sync — travels under "everything" and "everything but the crop", because those are claims about the whole edit and an unrecognised operation is part of it (FR-NC-8). It does not travel under a hand-picked set, because that is a claim about kinds, and an unknown kind is not one of the kinds that were ticked. The settings page's "Copy crop and rotation" checkbox is gone, replaced by the same chips the preset sheet draws. It asked the right first question — geometry is the kind whose accidental travel destroys work — but it was the only question a boolean could ask. The field stays in `Settings`, read exactly once to seed the new set, so anyone who had ticked it keeps their behaviour. The chips are deliberately not in the develop column. Six of them there would set the width of the whole sidebar, which is the bug `ChipGrid`'s comment records at length. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>	2026-08-29 20:38:19 +02:00
dtourolleandClaude Opus 5	bd33487054	Say which axis each export dimension is, in the one place that renders ... The box modes put two numeric fields one above the other, and on screen they are two anonymous numbers: `TextRow` draws its label behind the field rather than above it, so "Width" and "Height" never appear. That fault is older than this feature — the storage panel's cache sizes have the same missing labels, and the single "Size value" row always did — and it belongs in its own change rather than being fixed under cover of this one. But one unlabelled number is survivable and two are not, so the axis goes where the page does render it: the unit. It reads "3840 px wide" above "2160 px high", which is the sentence the user is trying to write anyway. The `label` bindings stay correct and stay where they are, so this becomes redundant rather than wrong the day `TextRow` is fixed.

dtourolleandClaude Opus 5	3bb68cff69	Export at an exact resolution, and offer the panels worth naming ... Export sizing could bound an image but not fix it. Long edge, short edge and percentage all preserve the aspect ratio by letting one dimension fall where it may, which is right for most work and useless against a display that accepts one resolution and rejects everything else — a television's art mode, a digital frame, a wallpaper slot. FR-EXP-3 has always listed both halves of the answer, and this adds them. **Fit box** scales to fit inside a width and height, so nothing is thrown away and the result is smaller than the box on one axis unless the crop already matches it. **Fill box** scales to cover the box and cuts the overhang off the middle, so the file is exactly the pixels asked for. Fill is the only mode in the file that discards image data, so two things about it are worth stating. The overhang comes off symmetrically: the crop tool is where a photographer decides which part of a frame survives, and this stage having an opinion of its own would fight it. And locking the crop to the same ratio leaves nothing here to cut, which is the workflow the two features are meant to be used in. With upscaling off and a source too small to cover, a fill box keeps its *shape* rather than falling back to the source's: exporting a 3:2 file where 16:9 was asked for is silently wrong in exactly the way the mode exists to prevent, so the box shrinks instead. The existing rule — clamp, never fail — is otherwise unchanged. Four panel sizes are offered as buttons beside the fields. Getting 3840 x 2160 by typing four digits twice is a step at which the mistake is discovered after the upload rather than before it. They fill in the numbers and nothing else, in particular not the fit/fill choice: both are legitimate against a screen, and guessing would discard the edges of a photograph for a user who wanted them. The list is panels rather than platforms, because a screen has one exact pixel count for ever where "what a photo site wants" would rot in the file.

dtourolle	f12aece07e	Make storage pluggable, and prove it with a folder backend ... `RemoteBackend` existed from the first release and bought nothing it was designed for. Seven files in `dr-ui` constructed a `NextcloudBackend` directly, an account *was* a server URL beside a DAV user id, the local cache directory was named after a hostname, and the launch screen knew that signing in meant a browser handshake. The trait was real; the seam was documentation. A trait over operations is only a quarter of it. Pluggable storage needs four things, and this adds the other three: - **Capabilities** — already there, and the reason the engine can drive two backends at the speed each actually runs at. - **Configuration** — `dr_sync::Account`: where a library lives, in whatever form its connector addresses, with no server in it. Loads every existing config unchanged (`backend` defaults to `nextcloud`, `endpoint` is stored under its historical `server` key), and `Account::namespace()` reproduces the old catalog directory byte for byte, because changing it would abandon a catalog, its thumbnail shards, and the sidecars holding unsynced offline work. - **Registration** — `BackendProvider` and `BackendRegistry`. `ui/dr-ui/src/remote.rs` is now the only file above `dr-sync` that names a connector. `Connection` (an account plus an optional `Secret`) replaces the credentials-and-user-id pair that was threaded through fifteen signatures in an order that could be swapped. `Secret`'s inner string is reachable only through `expose()` and its `Debug` prints `Secret(***)`, so the indirect leak — a `{:?}` on anything holding one — no longer compiles into a leak. Nextcloud is unchanged and keeps every peculiarity: propagating ETags, chunked upload v2, `oc:fileid`, the `oc:permissions` probe on a refused PUT, the 423 retry classification, Login Flow v2. Those are what the capability model exists to serve, not something to hide. `dr-sync-folder` is the second connector: a local disk, a network mount, an external drive, or a folder a Nextcloud client already syncs. No account, no credential — the route that works where no secrets daemon does. It declares `LocalEtags` rather than claiming propagation a POSIX directory cannot provide, which costs nothing because 50k `stat` calls are not 50k PROPFINDs. Identity is a path hash, not an inode: an inode survives a rename but differs between devices and is reused after a delete, so two machines would disagree about which photograph a thumbnail belonged to. Re-deriving a thumbnail is a cost; showing the wrong one is a bug. docs/storage.md is the contract — the traits, the four steps to add a backend, and what each connector declares. ARCH §8.0 and §8.4a, and FR-NC-13, say why.	2026-08-29 09:57:52 +02:00
dtourolleandClaude Opus 5	242374fd0f	Let the interface hold a backend without knowing whose it is ... `dr-sync` defines `RemoteBackend` and a capability model the engine adapts to, so a second backend can be added without touching the code that uses one. That boundary was documentation. Seven files in `dr-ui` constructed a `NextcloudBackend` directly, ten functions took one by concrete type, and exactly two call sites in the tree — both inside `dr-sync` itself — ever held the trait object. A WebDAV or local-folder backend would have had a well-written trait to implement and nowhere to go afterwards. The change is smaller than the finding suggests, because the trait was already right. Every method the UI has ever called on a backend — `get`, `put`, `list`, `delete`, `create_dir`, `move_to` — was already on it, so nothing had to be added and no behaviour moved. Ten signatures widened to `&dyn RemoteBackend`, sixteen constructions became `remote::connect`, and `remote.rs` is now the only file in the interface that names a connector. `connect` returns `Result<Box<dyn RemoteBackend>, RemoteError>`. The error type is `dr-sync`'s rather than the connector's, which is why every call site kept its shape — the `match`, the `let Ok(..) else`, and `.map_err(ScanFailure::local)?` all still read as they did. One wrinkle worth recording: `&Box<dyn Trait>` does not reach `&dyn Trait` on its own. The compiler reaches for unsizing, which wants `Box<dyn RemoteBackend>: RemoteBackend`, and reports a confusing missing impl rather than suggesting a deref. Twelve call sites therefore say `&*backend`, and two say `let backend: &dyn RemoteBackend = &*backend` where a borrow is shared across lanes. What this does *not* do is abstract credentials. `AppCredentials` is an app password from Login Flow v2 — a Nextcloud protocol, not a general notion of authenticating to a remote — and seven files still name it. An OAuth token, a bucket key pair and an app password have no useful common shape, so deciding what an account is across backends before a second one exists would be a confident guess. code-health.md CH-2 now records that as the remaining half, and it should wait for the backend that forces it. Verified: fmt clean, clippy clean at -D warnings, 2041 tests pass. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-27 19:51:23 +02:00
dtourolleandClaude Opus 5	25c88d9dbd	Start face indexing from Settings ... Beside the thumbnail sweep, because it is the same kind of thing: a job that runs for an hour, is asked for once, and reports into the activity list above it. It is also downstream of that sweep -- detection reads the proxies it builds -- so the two belong in that order, and the coverage line says how many images are waiting on a proxy rather than only how many are left to index. The button drives the Identity Manager's own state rather than a second copy, so it cannot disagree with that screen about whether a pass is running, and either place can start or stop it. The pass now opens an activity row. The caption promises progress will appear in the list above, and without a row it would not: the button would be the only sign anything was happening, invisible from every other screen. Coverage is read when the Settings page opens. The figures live in the catalog and this page deliberately holds no session, so they arrive through a closure rather than being kept current -- they are only ever looked at while the page is on screen, and the check is two counts and an indexed scan. Also adds DARKROOM_NO_SYNC. Redirecting XDG_DATA_HOME isolates a test launch's catalog and thumbnails but not its server, and I found that out by pushing a test catalog over the live one. The guard sits in start_derived_sync rather than at its three call sites, because the sweep firing a sync is correct and a flag checked in three places is one that gets missed in a fourth.

dtourolleandClaude Opus 5	fa4ad6e2d6	Drag the date range on the axis it is chosen from ... The range could be turned on with a finger and not aimed with one. Its two ends were typed as `YYYY-MM-DD` into 108px fields behind a soft keyboard, to name days already drawn on the axis a thumb away; and the chip that seeds them takes its span from the timeline's zoom and pan, which are a wheel and a middle button. A touch screen has neither, so on Android the filter was a switch with no aim. The band is now on the timeline. Two ends with grips, dragged along the bars, released to filter — the histogram was already how a period is found, and this makes it how a period is stated. Both ends snap to whole days, which is what the typed fields mean, what `show_range` reads back out, and a floor under a range dragged shut. The fields stay for what dragging cannot do: name an exact day, and say in words what the range is. For that to work the axis had to stop following the range. Redrawn to the band, it moved the ground under the very handles doing the narrowing, and there was nothing outside the range left to widen back into. While there: a fixed number of equal bins instead of calendar buckets. Between one calendar unit and the next the bar count is free to wander by a factor of twelve, so zooming in halved it two steps out of three — the same picture drawn wider until it jumped back to fine. Equal bins also include the empty ones, so a bar's position on the track and the date under it are finally the same quantity; before, a library with gaps drew a February six months wide and the marker, the band and a click all pointed somewhere else. The count is a setting, 32 or 64, because the right answer is a question about the screen. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-23 18:42:42 +02:00
dtourolleandClaude Opus 5	44f0a4971b	Show the folder picker on the platform that needs it most, and upload at once ... Two faults, both of my own making, reported from the tablet as "I cannot select a location" and "it does not upload". **The picker button was gated on `target-selected == 1`.** That index was Remote's position while both targets were offered. Making the target list platform-aware narrowed Android's to Remote alone, so Remote became index 0 and the button disappeared — on the one platform where the picker is the *only* way to set a destination, since a device folder is not reachable there at all. It is gated on a boolean derived from the target now. An index into a list whose length varies is not a fact about the target, and writing it as one is what made a correct change break the thing it was meant to fix. **A queued export waited for a sync pass.** Staging first is deliberate — an export is finished on disk the moment it is written, and offline is then just a longer queue — but nothing drained the outbox until the next sync, so "Queued for Exports" sat unchanged and read, fairly, as an upload that never happened. A finished batch that wrote anything now drains immediately. The sync-pass drain stays: the first makes an upload feel immediate, the second is what eventually delivers the exports made in a tunnel. Committed without the parallel session's in-flight collection work, which is mid-save and does not compile; verified by stashing it and building this tree alone. 281 dr-ui tests pass, clippy clean.

dtourolleandClaude Opus 5	8ea92545df	Stop the export folder forgetting itself, and let Android reach one ... Three faults, compounding into an export that could not be made to work on a tablet at all and a destination that appeared to reset on its own. **Switching target destroyed the destination.** One field held both a filesystem path and a remote folder, so changing the target had to clear it — `/home/x/Exports` carried to the server would have offered to create a folder called `home` at the library root. The consequence was that merely looking at the other option threw away the destination already chosen, which reads, correctly, as a setting that will not stick. There are two fields now. Each target remembers where it was pointed and switching is free; `active_destination` picks between them so no caller can reach for the wrong one. **The library root read as "unset".** The picker opens at the root, so confirming it where it opens stored an empty string — indistinguishable from "ask each time" and looking exactly like the picker had done nothing. Empty now means the library root for a server destination, which is a real folder and the one the photographs are already in; it means "ask" only for a device folder, where no path is worth assuming. The page labels it so. **Android defaulted to a target it cannot use.** A device folder there means the Storage Access Framework, which provides no filesystem path (ARCH §6.9) and is not implemented — so the default target could never succeed however the destination was filled in. The export button said "no export folder is set", the settings page offered no way to choose one, and the only way out was to guess that the other target was the working one. The device target is now absent from `ExportTarget::available()` on Android and the default there is the server, which needs no platform work at all. A settings file carrying an unreachable target — copied from a desktop, say — is corrected on read rather than left to fail at the last step. Seven tests, each named for the fault it prevents returning. The compatibility one matters most: a file written before `remote_destination` existed keeps its device path and gains an empty remote one.

dtourolleandClaude Opus 5	cb1d2be240	Choose the export folder by walking the server, not by typing it ... The destination for a Nextcloud export was a text field. Nobody recalls the exact spelling of a path three levels down, and getting it wrong does not fail — `create_dir` makes whatever was typed, so a misremembered folder becomes a new one at the root and the exports are somewhere nobody looks. So it is picked the way the library root is picked, using the same `FolderBrowser` model the launch screen drives: up, into, and "use this folder", confirming the folder currently *shown* rather than one selected in the list. Same rule in both places, so the phrase means one thing. The model is shared; the worker is not. `settings_ui::spawn_folder_list` is a near-twin of the launch screen's, because that one reaches into the `LaunchController` for its session and reports onto the launch screen's error line, while this one is handed credentials and writes to the settings page. Factoring them together needs a function taking both controllers or a trait implemented twice to abstract two call sites — more machinery than the twenty lines it saves. What matters is shared already: navigation behaves identically because both drive the same model. The callbacks are wired in `lib.rs` rather than in `settings_ui::wire`, because listing a remote folder needs credentials and the settings page holds no session on purpose — it is reachable before a library is opened and must not depend on one existing. With no account the picker says to sign in first, rather than showing an empty list that reads as a server with no folders. Details that are decisions rather than accidents: the picker opens at the library root rather than at whatever half-typed path is in the field, which would list nothing and look broken. The listing area is a fixed 180px, since a folder with sixty children would otherwise push the rest of the settings page off the bottom. "Up" is disabled at the root rather than hidden, so the row does not jump as the user navigates. A failed listing leaves the picker open on the folder it was showing — where the user had got to is not something to discard over a dropped request. And the chosen folder saves immediately like every other setting on a page that has no Save button. The poll timer lives on the controller for the reason `LaunchController` keeps its own there: a `slint::Timer` stops when dropped, so one local to the function that starts it would be collected before the listing arrived. Carries in-flight work from a parallel session — a segmentation pass in dr-gpu, a sidecar cache, and the develop panel's continuing changes. 1020 tests pass, fmt clean. One clippy warning remains and is not mine: `sidecar_cache::dir` is unused while that work is in progress. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>	2026-08-17 07:12:01 +02:00
dtourolleandClaude Opus 5	e00c99b864	Let a photograph leave: an export button, and a cache to leave from ... dr-export could turn a frame into bytes and nothing could ask it to. This is the button, and the place the bytes go. **Everything is staged first.** An export bound for the server is written to a local outbox and uploaded afterwards; offline is not a special case, it is the same path with a drain that finds the server absent. Doing it the other way — upload directly, stage only on failure — makes the failure path the one that is rarely exercised and always broken, and a network drop mid-batch leaves some exports existing and some not with nothing recording which. Staged first, an export is finished the moment it is written and the upload is a promise kept later. The outbox sits beside the catalog rather than under the cache. dr_catalog's cache already draws that line: passive entries are a convenience and go under LRU, pinned ones are a promise and never do. An export awaiting upload is a promise — the user was told it succeeded — and sweeping it for disk would destroy the only copy. Bytes are written before the destination record, so a kill between the two leaves an orphan the drain ignores rather than a record pointing at nothing. The status line says "Queued for Exports/2026", never "Exported to Nextcloud", until it has actually landed. There is a test asserting that wording, because the tempting shorter sentence is a claim the app cannot keep. The drain runs on the sync pass, before the shards: a thumbnail shard can be rebuilt from the originals and the catalog is an index, but a queued export exists nowhere else. `DevelopSession::render_for_export` renders the framed size rather than reusing the frame on screen, which is deliberately viewport-sized (FR-DSP-1) — encoding that would hand the user a soft, screen-sized file with nothing to say anything had been lost (FR-EXP-9). One compromise, recorded rather than hidden: the export runs synchronously on the UI thread, so the window is unresponsive for the few hundred milliseconds a full-resolution render and encode takes. Moving a DevelopSession and its GPU pass to a worker is a larger change than one button earns, and it is batch export that makes the wait intolerable rather than merely noticeable. Still missing: the Nextcloud folder *picker*. The destination is typed into Settings for now. `FolderBrowser` in launch.rs is already the reusable model for it — it browses a remote tree and nothing about it is specific to choosing a library root — but wiring it into the settings page needs a listing worker and browser UI there, which is its own piece of work. Carries in-flight work from a parallel session — presets, the develop copy and paste, and the node schema's `presentation` and `enum` support. One misplaced callback in settings_ui.rs is moved from `render` to `wire`: registered in `render` it borrowed a `&SettingsController` into a 'static closure and would not compile, and that file's own docs say render pushes properties while wire connects callbacks. 992 tests pass, clippy and fmt clean. Traceability 48.3% -> 51.0%. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>	2026-08-16 23:58:17 +02:00
dtourolleandClaude Opus 5	151dcc3c02	Make a file out of a photograph ... Export existed as a settings page and nothing else: format, quality, colour space, five sizing modes, a filename template and a metadata switch, all configurable in detail, and no way to produce a single file. dr-export is the other half. **It returns bytes and a name, and writes nothing.** An export has three destinations with nothing in common — a path on Linux, a SAF document on Android where there is no path at all (ARCH §6.9), and a PUT to a Nextcloud folder — so a crate that opened the file itself would serve one of them and be rewritten for the other two. The caller places the bytes. Resize, then sharpen, then encode, in that order and for a reason: output sharpening compensates for the softening the resample introduced, so its strength scales with how much scaling actually happened, and sharpening before shrinking would throw the result away. Lanczos-3, separable, with weights computed once per output row — FR-EXP-4 asks for Lanczos or better because a box filter turns a distant fence into moiré. Collision handling takes the "is this name taken" test as a closure rather than looking at a directory, because there is no directory it could look at that works everywhere. That shape is not politeness toward Linux: Android's createDocument renames on collision by itself and cannot overwrite at all, so all three CollisionPolicy settings need the answer *before* anything is created. Overwrite, Skip and Increment are each tested, and Increment gives up after ten thousand rather than spinning against a destination that reports everything as taken. Three things are honest rather than done: - **Colour space.** sRGB only. The shader encodes and clips to sRGB before this crate sees a pixel, so tagging a file Display P3 would claim a gamut it does not contain. Refused with a typed error instead of mislabelled; honouring it is a pipeline change (FR-EXP-2). - **AVIF and JPEG XL.** No encoder. libaom and libjxl are C, ravif is slow enough to change what a batch feels like, and the settings page offers both because FR-EXP-1 lists them — so asking for one says so rather than writing a JPEG under a .avif name. - **16-bit TIFF** is a real 16-bit file carrying eight bits of information, because AdjustPass renders to Rgba8Unorm. Widened by *257, not <<8, so white lands on 65535 rather than a quarter-percent grey. Making it mean what it says needs the composer told what format to write. Metadata is not written at all, which satisfies the half of FR-EXP-8 that matters most: strip_location defaults to on, and a file with no EXIF block has no GPS tag. Retaining camera and copyright when asked is not implemented and cannot be faked by omission. Also here: - `AdjustPass::export_pixels`, ungated where `read_output` is behind a feature. The two are the same transfer and opposites in intent: reading pixels back to *display* them is what ARCH §6.1 forbids and AC-8 asserts against, while reading them back to encode a JPEG is the only way a file has ever been made. Separate methods so the instrumentation can count one without counting the other. - `ExportTarget`, so a destination can be a folder on the server. On Android that is the only destination needing no platform work whatsoever — a PUT against create_dir, already on the RemoteBackend trait, behaving identically on both platforms. Switching target clears the destination, since a path is not a remote folder and carrying one across would offer to create a folder called `home` at the library root. Verified end to end rather than by unit test alone: `cargo run -p dr-export --example export` decodes a frame, runs the develop chain on the GPU at full resolution, reads it back, and writes all five formats — 27 ms for a full-size JPEG, 165 ms with a Lanczos reduction to 1200px. ImageMagick agrees the 16-bit TIFF is 16-bit. dr-export cross-compiles clean for aarch64-linux-android; all three encoders are pure Rust, which is why they were chosen. 944 tests pass, clippy and fmt clean. Not yet wired to a button. The develop view has no export action, so nothing in the running app can reach any of this yet.

dtourolleandClaude Opus 5	03326242a1	Make the CI checks say what they mean, and format the workspace ... The Android job's "Verify minimum API level" step has never verified the minimum API level. It took the first `*.so` anywhere under the target directory, which is a host proc-macro from debug/deps — an x86-64 object built by the runner's gcc, whose .comment section cannot mention Android and so can never contradict the expected value. It now reads the artifact under the target triple, compares against MIN_API parsed from the Dockerfile rather than a second copy of the number, and fails on a mismatch. Both sides are checked non-empty first: two failed parses would otherwise compare equal and pass, which is the same silent success in a new costume. The Android image installs one SDK package per layer and keeps the output. sdkmanager is a JVM program that aborts when it cannot get memory, and the single `> /dev/null` step reported that as a bare "exit code 134" while a retry re-downloaded everything that had already succeeded. tools/ci-local.sh runs all four jobs — desktop, android, layering, traceability — against the host toolchain, which is pinned to the same 1.92.0 CI installs. Its matrix check compares regeneration against the working tree rather than against HEAD: CI starts from a clean checkout, so git's answer is the right one there and reports every local run stale here. The rest is rustfmt across the workspace, and the clippy findings that surfaced once it did: manual_contains in dr-thumbs and collections_ui, a map iterated as pairs for its keys, an index loop over a slice, and two runtime assertions on a constant now made at compile time.

dtourolleandClaude Opus 5	fa12afed18	Keep originals on this device, by pin and by use ... Fills in `image_cache`, which the previous commit's "On this device" filter read but nothing wrote. Also carries in-flight work that shared these files: the Android TLS root store, the settings page, and a regenerated traceability report. # Two populations, deliberately separate An original is kept here for one of two reasons, and conflating them produces the exact failure the feature exists to prevent. **Pinned** originals were asked for. Pinning a collection before a trip is a promise, so pinned rows are never evicted and never counted against the budget — a cap that could silently delete a pinned trip would make pinning worthless, because it could not be relied on without checking. **Passively cached** originals are a side effect of working: develop already downloads the whole file, so keeping it costs no bandwidth and saves the entire transfer next time. This population is what the budget bounds, evicted least-recently-used, because it otherwise grows until a day of culling fills a disk. Sharing one budget would let a large pin starve the passive cache, or let browsing evict a pin. They are separate. # What was built `dr_catalog::cache` owns the bookkeeping — held tier, size, last use, pinned — and writes the bytes; deciding to download stays with the caller, which is what keeps a crate with no network out of the network's business. Files are written to a temporary and renamed, so a dropped connection cannot leave a truncated file recorded as a complete original. They are named by image id, not filename: `Photos/IMG_0001.CR2` and `Trips/IMG_0001.CR2` are different photographs, and a flat cache keyed on the name would serve one for the other. `spawn_full_fetch` became read-through. A hit is a disk read; a miss stores what it downloads and enforces the budget. A cache that cannot be opened is a miss, not a failure to open the photograph. Pinning writes intent — `tier_desired` — without downloading, so the button responds immediately, and `spawn_pin_fetch` fills it in sequentially afterwards. Sequential because these are tens of megabytes each: the lanes that make the thumbnail sweep fast buy little against one connection's bandwidth and cost a great deal of memory. A pin interrupted by a lost connection resumes from where it stopped. Schema v5 adds `pinned` and `path`. `pinned` is a column rather than something inferred from `pinned_by_rule`, which is ON DELETE SET NULL and so cannot answer for an image whose rule was deleted. A v4 catalog migrates in place; existing rows default to unpinned, the safe direction. The budget and "keep opened originals" come from the settings page rather than a constant, and are applied at startup rather than only on change — a cache capped at 2 GB last session would otherwise spend this one filling to the default. Turning off keeping leaves what is already cached readable: those bytes are paid for, and refusing them would re-download images sitting right there, including pinned ones. Also removes a doubled `#[test]` introduced in the previous commit. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>	2026-08-11 21:12:01 +02:00
