dtourolleandClaude Opus 5	474dcf0bf6	Let Compose lead the attributes, as their own doc always said ... `Attribute::ALL` claims to be "roughly the order a photographer works in" and then listed framing fifth, behind tone, colour and detail. Framing is the first decision made about a photograph and the one every later judgement is made inside — there is no sense balancing tones across a frame about to lose a third of its width. The contradiction was harmless while the list only fed a row of chips nobody reads in order. It stops being harmless now that the same list drives a column read top to bottom. `declared::Attr::ALL` moves with it. The two are separate spellings of one vocabulary and a test asserts they agree, which is what caught this rather than the order silently disagreeing between the YAML front end and the crate.

dtourolleandClaude Opus 5	1ad35e2b87	Read the library's sidecars, so a cull done elsewhere arrives ... Judgements only ever travelled outward. A rating went to the catalog and to the photograph's sidecar, the sidecar reached the server, and there it stopped: the scan indexes files, `derived_sync` exchanges thumbnails, face shards and collections, `dr_catalog::merge` reconciles everything in a catalog except `versions.rating` and `versions.flag`, and the one sidecar reader that existed ran when a single photograph was opened in develop and handed its answer to the develop graph. `JobKind::ReadSidecar` was declared for exactly this when the job queue was written and was never enqueued or handled anywhere. The grid draws `versions.rating`. So a day of culling on the tablet could not reach the laptop by any path the application had, and the laptop's catalog says so plainly: 23,568 images, one of them judged. `pull_sidecars` closes it, off the back of work the scan already does. `dr_sync::scan` reports the `.drsc` files it meets in listings it was making anyway — no extra request, and a directory whose ETag is unchanged is still pruned before it is listed at all. A new `sidecars` table records the ETag of each one this device has taken in, so the fetch is one GET per sidecar that genuinely changed rather than one per photograph. A library nobody has edited costs nothing. The judgement is taken rather than maximised. The sidecar is the authoritative store and the fuse has already settled any contest between devices on `revision`, so lowering a rating from four to one on the tablet lowers it here — taking the larger would have refused every demotion the photographer ever made, which is most of what a second pass over a shoot is. A zero is the exception: it means *never judged*, not "judged zero", so a sidecar carrying none cannot erase a star this device holds. That is `merge_judgement`'s asymmetry and it carries the same known cost — clearing a rating does not propagate. A sidecar names a stem, so both halves of a RAW-and-JPEG pair are judged: they are one photograph (FR-CAT-11) sharing one document, and judging only one of them would leave the grid disagreeing with itself over which it drew. The `LIKE` that finds them is a filter, not the decision — `sidecar_path` is applied to every candidate, because a folder is entitled to contain a `%` and a rating landing on the wrong frame would be silent and permanent. Failing to read one is not a failure to scan: the ETag goes unrecorded, the ratings already here stay where they are, and the next scan tries again. The count is reported to the status line as well as the log, because a grid that silently gains three hundred stars is indistinguishable from one that has gone wrong — and because while this number was structurally zero there was nothing to tell the photographer their cull had not arrived.

dtourolleandClaude Opus 5	ca2a135e28	Let two devices name the same photograph's version the same way ... A version's uuid is the identity a cross-device merge keys on, and it was minted at random, per catalog, per image. Two devices indexing one Nextcloud library therefore held two different uuids for the same photograph — so the sidecar they shared collected a `default = 1` block each, `Version::merge` was never handed a matching pair to reconcile, and an afternoon's culling on the tablet did not exist as far as the laptop was concerned. `crate::merge` has said so in a comment since it was written: version uuids do not reconcile across devices, a uuid-keyed join unions nothing, so keywords are landed on the local default version instead. It named the problem and worked around it. `rating`'s own comment asserted the opposite — that generating the uuid here was what made it a cross-device identity — and `library::amend` repeated the claim. Uniqueness was never the difficulty; agreement was. `derived_version_uuid` computes it from `oc:fileid` instead. The server assigns that integer, every client pointed at the library sees the same one, and it survives a server-side rename and move — the three properties that already made `ASSIGN_BY_FILE_ID` prefer it to a content hash. The layout is a UUIDv8 (RFC 9562, an application-defined form) carrying all sixty-four bits verbatim across the variable fields with a fixed tag in the node field, so the mapping is injective by construction rather than by a hash's good behaviour, and a uuid in a sidecar can be read back to the file it belongs to by eye. A library with no server behind it has no shared identity to derive and keeps a generated one. The split is still reachable there if the folder is synced by something else; `Sidecar::fuse_default_versions` repairs that case rather than preventing it. Deriving it for new rows alone would have fixed nothing — every image in an existing library already has a version, so every one of them would have carried on writing to its own rival identity. `align_default_version_uuids` moves them, and runs from `schema::backfill` on every catalog open. It selects on the tag in SQL, so a catalog already realigned matches no rows and writes nothing, and it declines rather than fails where a virtual copy already holds the target.

dtourolleandClaude Opus 5	601c984894	Fold a photograph's rival default versions back into one ... Picking the newer of two default versions stopped the wrong edit being shown, but it did not close the split: the losing version stayed in the file, and a device holding disjoint work — a crop made here, an exposure change made there — still contributed only one of the two. Worse, the next write made it larger. `amend` looks its version up by uuid, neither of the two was ours, so the miss minted a *third* `default = 1` block and the file grew one rival per device per photograph. `Sidecar::fuse_default_versions` folds them down. The version with the highest `(revision, modified)` is the accumulator and every other default is merged into it as the remote, which is what makes the fold order-independent — `Version::merge` raises its own revision to `max + 1` as it goes, so merging a chain in ascending order stops being ascending after the first step and a third device would be dropped. Contested values resolve to the winner, disjoint keys survive from both sides because the merge is key-wise, and ratings come across under `merge_judgement`, so a device that never judged the frame cannot erase one that did. The result is a function of the file's bytes alone, so two devices that fuse independently reach the same document and converge instead of overwriting each other. Called wherever a sidecar is parsed: - `amend`, with the write's own uuid, so the fold lands on the identity this device is about to use and the lookup below it hits instead of missing. - `spawn_sidecar_fetch`, so opening a photograph shows everything done to it rather than whichever half won. - `drain_one`, because `merge_into` reconciles by uuid and would otherwise publish the split rather than resolve it. - `presets::load_local` and `save_local` — a local sidecar's folder may be synced by something else entirely, and gets the same split. A file with one default under the expected uuid comes back byte-identical, so this costs nothing on the ordinary write and no sidecar is uploaded merely for having been read.

dtourolleandClaude Opus 5	98fcf8e98e	Ask which edit is newer, not which uuid sorts first ... A photograph edited on two devices ends up with two `[version]` blocks in one sidecar, both marked `default = 1`. Five of the thirty-eight sidecars in the local cache are in that state right now. `default_version` answered with the first `is_default` it met in map order, and the map is keyed on uuid — so which device's work the photographer saw was decided by which randomly minted uuid happened to sort lower. On `IMG_20130625_0033` that is `0545c20a` over `679fe872`: a four-star rating from the twenty-first of August standing in front of the one-star made on the thirtieth, with nothing anywhere saying the newer judgement existed. Resolved by `(revision, modified)` instead, which is the discriminator `Version::merge` already uses — revision first so that a device with a skewed clock cannot win by claiming a later timestamp (FR-NC-8), and the timestamp only to break an exact tie. This makes the reader pick the right one. It does not make the two converge: the edit that lost is still in the file, and a device that holds disjoint work — a crop here, an exposure change there — still only contributes one of them. That is the next commit. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-09-05 16:13:49 +02:00
dtourolleandClaude Opus 5	a56baa9042	Let rustfmt have the assertion it reflowed ... The closure taken down to `&dyn Operation` needed its call site re-wrapped, and I wrapped it by hand rather than letting rustfmt decide: it fits on one line at the workspace width. `cargo clippy` was run on the change and `cargo fmt --check` was not, which is the whole of how it got through — the two catch different things and CI runs both.

dtourolle	f0ee53ec09	Merge: the optical corrections, connected at last ... Four files' worth of lens correction existed, was tested, and had never touched a photograph. `compose_warps` had no callers, `dr-lens` had no dependents, and `ops/vignetting.rs` had no declaration in `ops/` — so `Attribute::Optics` was a category the tab strip could only ever filter out for having no rows in it. Distortion, chromatic aberration and lens vignetting now render, carry their parameters through the sidecar and the undo stack, and take their coefficients from the Lensfun database when the file names a lens it knows. The panel says which of "no lens recorded" and "no profile for this lens" it is, because an automatic correction that silently did nothing is worse than one visibly unavailable. One real bug on the way: `lens.rs` and `framing.rs` both documented the shader's `p` as corner-normalised, and it is not — its length at the corner is `0.5 * length(aspect)`, about 0.901 on a 3:2 frame. Every Lensfun polynomial would have been evaluated short of where it was fitted, by a factor varying with the aspect ratio, which reads as a correction that is merely too weak. The category vocabulary moved with it. `Attribute::Geometry` is `Compose` — named for the photographer's decision rather than for the maths it shares with the lens corrections — and a film stock stopped claiming to be both tone and colour, which had put "Kodachrome" in two groups it belongs to neither of.	2026-09-05 15:35:44 +02:00
dtourolleandClaude Opus 5	2841eaf9a1	Take the layer-chain test's closure down to &dyn Operation ... `clippy::borrowed_box` is denied by the workspace lint set, and the closure added with the optics exclusion took `&Box<dyn Operation>` — a borrow of the box rather than of the thing in it, which says nothing the plain trait object does not. Caught by `cargo clippy --workspace --all-targets -- -D warnings`, which is what CI runs and what the workspace tests do not: a lint on test code only appears when the tests are compiled as a clippy target.

dtourolleandClaude Opus 5	c4ddcbe0f7	Look the lens up and say plainly whether one was found ... `dr-lens` has held a complete Lensfun lookup — distortion, TCA and vignetting coefficients from a lens name, a focal length and an aperture — with no dependents anywhere in the workspace. The three corrections it feeds now exist in the graph, so this connects the two and finishes the chain. The coefficient structs stay duplicated. `dr-pipeline` is organised around having no dependencies so its codegen is testable without a device or a database (ARCH §6.5a), and `dr-lens` carries an XML parser and 5.5 MB of profile data. Neither crate can convert to the other, so the conversion goes above both, in `develop.rs`, which is the only place that sees them together. Both traits grow the same defaulted door. The optical corrections do not sit on the same side of the fetch — distortion and CA rewrite coordinates and are `Warp`s, vignetting applies a gain to the pixel already there and is an ordinary node — and fanning a profile out by which trait each happens to implement would make the caller reason about that distinction. Each correction takes its own share of the whole profile instead, and `set_lens_profile` walks both lists identically. The lookup happens in `set_source_metadata` rather than in its caller, because that is the one place a session is told which file it came from. Doing it there makes it unforgettable, in the shape `FilmRebake` already uses for the other derived thing — and, more to the point, makes *clearing* unforgettable: a session that opened a second photograph while still holding the first one's profile would correct it for the wrong optics, invisibly, in a way that looks exactly like the lens. It needs the whole shot and not just a name. Distortion is interpolated across a zoom's focal range and vignetting depends strongly on aperture — a fast prime can be two stops down in the corners wide open and clean by f/8 — so a lookup missing either returns coefficients measured for a shot nobody took. Missing any of the three refuses rather than guesses. A profile is derived, not persisted: it comes from the file's EXIF and a database, so it is not a parameter, not in the sidecar and not undoable. What is an edit is the manual trim beside it, which each correction composes with the measurement — so a photographer can lean on it, override it, or work without one. `InfoPanel` gains a lens line, and it distinguishes three cases rather than two. `dr-lens` states the rule it exists for: an automatic correction that silently did nothing is worse than one the user can see is unavailable. A session with no header draws nothing, a header naming no lens reads "Lens not recorded", and a lens the database has never heard of reads "· no profile". Collapsing the last two would send somebody hunting for a profile that was never missing — which, for third-party and adapted glass, is the ordinary case.

dtourolleandClaude Opus 5	a1165ef182	Put the coordinate-domain lens corrections into the graph ... `lens.rs` has held a `Warp` trait, a composer and two implementations — distortion and lateral chromatic aberration — since they were written, and `compose_warps` was called by nothing outside its own tests. The corrections existed, were correct, and never touched a photograph. `EditGraph` now holds them, and `compose_full` emits them between the framing prologue and the fetch. Distortion first, then CA: each warp receives the position the previous one produced, and lateral CA is a magnification about the optical axis of the *undistorted* frame, so measured on a barrel-distorted one it would be fitted to a radius no profile describes. They reach the panel the way framing already does — through `capabilities`. That was the one open question and existing practice answered it: framing is also not an `Operation`, also has parameters a photographer sets, and also arrives through that list. Because `Preset::capture` walks the same list, the sidecar, the clipboard and the undo stack carry a warp's parameters with nothing registered anywhere, and no file under `ui/` names one (FR-DEV-3a). `state()` destructures `EditGraph` field by field precisely so that a new field cannot be forgotten, and it was not. Chromatic aberration is the only thing that samples per channel, and `splits_channels` is what keeps everything else from paying for it. Red and blue are fetched from positions green is not — green is the reference and never moves, so a wrong correction still leaves one channel sharp rather than softening all three. With no CA in the chain the single-fetch path is emitted instead. The interpolating sampler is now chosen by framing *or* an active warp. Asking framing alone would have nearest-neighboured a distortion correction on an unstraightened frame, and that aliasing reads as a bad profile rather than as a missing filter. The warps go in the geometry invalidation key rather than the colour one: they decide which source pixel a colour is read from, so a tile cached across a distortion change would keep drawing the previous correction. The pipeline cache needs nothing new — `hash_source` already covers the generated body, and uniform values never enter it, so arming a warp recompiles and dragging it does not. Both are asserted.

dtourolleandClaude Opus 5	e17b909d41	Connect the lens vignetting correction to the pipeline ... `ops/vignetting.rs` has carried a complete descriptor, polynomial, helper and test suite without an entry in `ops/`, so it was never in `chain()`. It reached no photograph and no panel, and `Attribute::Optics` was an empty category in consequence — filtered out of the tab strip for having no rows, by a chain that had never been given its only member. Declaring it needs the one thing the operation was written against and which did not exist. `wgsl_body` reads `radius`, and the module claimed "the composer publishes `radius` in the shader prologue for exactly this reason". It did not. `sample_source` now does, in both sampling branches, beside the `source_px` it already published for the same class of caller. It is corner-normalised there, which is the part that is easy to leave out. `p` spans ±0.5·aspect, so its length at the corner is 0.5·length(aspect) — about 0.901 on a 3:2 frame, not 1. Lensfun's polynomials are fitted against a corner radius of 1, so passing `length(p)` straight in evaluates every one of them short of where it was measured, by a factor that changes with the aspect ratio. It would have read as a correction that is simply too weak, which is indistinguishable from a bad profile. Both `lens.rs` and `framing.rs` asserted the normalisation `p` does not have; corrected. `order: 5` puts the correction ahead of the tonal stages, and the ordering is load-bearing rather than tidy. Recovering a corner means dividing by an attenuation below one — about two stops for a fast prime wide open — so run after the highlights have been rolled off and clipped, the lift has nowhere to go and the corners posterise instead of brightening. `layer_chain` now drops `Optics` as well as the neighbourhood operations. A local vignetting slider would have worked, which is what makes it worth excluding: `radius` measures from the centre of the whole photograph and a mask cannot move the optical axis, so it would lay a frame-centred radial ramp across the picture and multiply it by the mask. The existing exclusion covers operations that move and do nothing; this one covers an operation that moves and does something its name does not promise. The rule both share is now written down.

dtourolleandClaude Opus 5	8e7b1350bf	Name the frame's category for the decision, not the maths ... `Attribute::Geometry` becomes `Attribute::Compose`, and `film_sim` moves from `[tone, colour]` to `[effect]`. Two categories were doing the wrong job. "Geometry" describes what crop, straighten and the quarter turns do to coordinates — but it describes lens distortion correction exactly as well, and that is not a compositional choice at all. Naming the attribute for the photographer's decision is what separates it from `Optics`: one is what the lens did, the other is what they chose. The maths the two have in common is not the thing worth filing them under. A film stock declared both `tone` and `colour`, so "Kodachrome" appeared in the Light group beside exposure and again in Colour beside white balance — two places, neither of which is where anyone looks for it. It is neither: `Effect` is defined in this same file as "applied rather than corrected — a look, not a fix", which is what a stock is. That it moves tone and colour is true of every look, and is not what the attribute is for. `from_name` still accepts "geometry" on the way in. That string is persisted in `develop.copy_attributes`, and an entry it fails to parse is not an error — `presets::scope_for` logs it and drops it — so without the alias an existing settings file would have quietly narrowed what a paste carries. `name` writes the current spelling, so the file migrates itself the first time it is saved.

dtourolleandClaude Opus 5	95e854b5a2	Regenerate the gesture vocabulary over the library work ... `Traceability` stayed red after the matrix was regenerated, on its other gate: `gestures-check`. Same cause, second artefact. `docs/gestures.md` cites each gesture by `file:LINE`, and the library UI work moved the two selection-mode gestures down a hundred lines — 3923 -> 4032 and 3940 -> 4049 in `ui/dr-ui/ui/library.slint`. Nothing about the gestures themselves changed. `ui/dr-ui/src/gesture_book.rs` was already current, so this is the doc alone: 70 files scanned, 16 gestures, 2 places, gate PASS. Worth knowing for next time: `tools/ci-local.sh traceability` runs the self-test, the coverage gate and the matrix, but not `gestures-check`, so a clean local run does not prove this workflow green.

dtourolleandClaude Opus 5	c1069ce07e	Release 0.10.1 ... A bug fix release. Nothing here changes what DarkRoom is for since 0.10.0; it changes how often it does the thing it already claimed to do. The edits that went missing. A subject or category layer was stored as identity alone, on the reasoning that the pixels were reproducible by re-running the model — true, but nothing re-runs one except a photographer pressing "find subjects". So a reopened photograph rendered without its local adjustments and then saved that state back, and a batch export wrote three hundred files without the edits their photographer had made, over a log warning. The coverage now travels in the sidecar. Export also learned to write the photograph rather than the canvas, and to carry the photograph's header when the export is made from develop. Face indexing was reading previews. It ran against a proxy and then recorded the result as though it had seen the photograph, so faces smaller than the proxy could resolve were not missed, they were *concluded absent*. Indexing now runs on the native render, runs made against proxies too small to find a face are forgotten rather than trusted, and a sweep that fails everything says so instead of reporting a clean pass. Where you were. The photo roll opens on the frame it opened with, develop returns you to the photograph you were editing, the grid keeps its place when another screen covers it, and the photographer's position now travels between devices rather than being rediscovered on each. Startup. The catalog opens on a worker and the bundled models unpack on one, so a launch is no longer a page-by-page read on the way to the first frame; the app says it is starting before there is anything to say it with. The People rail builds the rows you can see, keeps portraits off the blocking path, and withholds the empty groups that used to fill it. Segmentation gained the half it was missing: the colour gate decided what belonged to a category and had no way to decide where its edge fell, so a refined sky kept the model's blocky outline no matter how the control was set. A marker-based watershed now puts each contour onto a real edge, and the refinement is a per-layer slider. Coverage 70.4% -> 70.6% (127/180).

dtourolleandClaude Opus 5	dabf63ed6d	Regenerate the matrix over the watershed and sidecar work ... `Traceability` has been red on master. The matrix records every tag as `file.rs:LINE`, so it goes stale two ways at once, and both happened here: - the `cargo fmt --all` sweep (710fcbc) moved lines under tags that did not otherwise change, which is drift with no change of meaning; - the segmentation and mask-storage work added tags and a requirement, which is drift that means something. Regenerated: 332 -> 334 files, 1058 -> 1086 tags, 179 -> 180 requirements defined, coverage 70.4% -> 70.6% (127/180). No code changes. The pre-commit hook regenerates this file whenever a taggable source file is touched, so the way it gets stale is a commit made with `--no-verify`.

dtourolleandClaude Opus 5	f6c9343bcc	Ask the pixels where the edge is, not just what belongs ... The colour gate decided *what* was in a category and had no way to decide *where* its edge fell. A colour test has no notion of an edge. So a refined sky lost its flag and kept the model's twenty-pixel-blocky outline, and no setting of the control could move that outline onto the horizon. This adds the second half: a **marker-based watershed**. The mask is eroded to give two markers, and the flood runs in the ribbon left between them, meeting along the most expensive line it can find. The cost is a sum of terms exactly as docs/segmentation.md §2 specifies — the photograph's own edges, and the colour model's disagreement. ## Why this is not the watershed §15 threw away That path failed because the merge *ladder* collapsed: 45,808 basins reduced to one region plus specks. There is no ladder here. Markers prevent over-segmentation by seeding rather than by merging afterwards, so the one component that broke is the one component this does not have. The markers are also better than the textbook's. scikit-image derives them by thresholding the gradient — guessing where objects are — where these come from a model that knows what sky is. Marker selection is what normally goes wrong with this method, and it was already solved. ## The gate still runs, and it runs first A flood cannot replace the colour gate. It only refines contours that already exist, and there is no contour around a flag precisely because the model never noticed one — the flag in the tests sits forty-five pixels from the boundary against a ribbon of six. The tests caught this; the first version of this commit had the flood standing in for the gate and the flag stayed. So the gate goes first and *creates* the contour, and the flood then puts every contour — the horizon and the new hole alike — onto a real edge. ## Erosion that does not delete flagpoles Eroding by a cell and a half destroys anything thinner than three cells: a mast, a bare branch, and equally a strip of sky between two of them. Those would be left unseeded and the flood would fill them from whichever side surrounds them, so a flagpole would come back — and come back *confident*. Erosion therefore stops at the ridge of the distance transform. Whatever would otherwise vanish keeps a one-pixel seed down its centre, floored at `min_thickness` so a hot pixel does not qualify. That floor also moves the signal-versus-noise decision out of colour space, where it was a share of a fitted distribution nobody can picture, and into image space, where it is a width in pixels a photographer can see. ## Two modelling errors the outward test found Both were invisible while the refinement could only subtract, because the gate was multiplied by weights that were already zero outside the mask. The moment the boundary could move outward they decided the answer. **A diagonal covariance is wrong along a gradient.** Sky moves along all three opponent features together — luminance up, red-green drifting, blue-yellow down — so treating them as independent charges a colour two deviations along that gradient three times over. Measured: sky fifteen rows past the sample scored 11.6 against a threshold of 11.34, so the model refused the very thing it was refining. The fit now carries a full 3x3 covariance, inverted by cofactors rather than by a dependency (D13, the NDK). **Eroded seeds understate the spread, always, in a known direction.** The sample is drawn from the middle of a category and never from its edge, so for anything with a gradient the colours nearest the boundary are exactly the ones left out. The broad mode is therefore fitted wider than its sample by `SHOULDER`. Same pixel: Mahalanobis 5.9 uncorrected, 1.5 corrected — the difference between refusing the horizon and reaching it. Only the broad mode is widened; the tight ones are what discriminate. ## What was given up Strict subtractivity. It bounded the damage and kept `scene.rs`'s partition true for free, and it had to go: a mask that may only shrink can sharpen a horizon inward but never outward, so wherever the coarse contour sat inside the true edge, the error survived every setting of the control. The travel bound replaces it. Everything beyond the ribbon is already a marker, so the flood never reaches it — not "can only remove" but "can only move this far", and the distance is the model's own uncertainty. That single bound also retires the connectivity test, the reachability radius and the separate additive path that an outward-growing rule would have needed. A blue car below the horizon cannot be gained, not because a rule forbids it, but because the flood is never there. `the_colour_gate_only_removes` keeps the older property where it still holds; `the_flood_cannot_travel_further_than_the_ribbon` holds the new one across the whole travel of the control. ## Cost The flood visits only unlabelled pixels, so confining it to the ribbon is not an optimisation added on top — it is what a seeded flood does. A ribbon of a few tens of pixels around one contour is a small part of a proxy. The distance transform is no longer cached, because it has to be measured from the mask as the gate leaves it and the gate moves with the control. That is one transform plus one flood per change of the control, against a precompute that runs the model once. Verified: fmt clean, clippy --workspace -D warnings clean, 63 dr-segment tests.

dtourolleandClaude Opus 5	710fcbc1bd	Format the face work with the workspace's own rustfmt ... Not authored in this session. `cargo fmt --all` reformats every crate, so running it while working on `dr-segment` picked up five files from the recent face and library work that had been committed unformatted. Committed on its own rather than swept into the change that happened to produce it: the diff is pure whitespace, and mixed into a commit that alters an algorithm it would be noise in exactly the place someone is trying to read carefully. `cargo fmt --all -- --check` is a CI gate (tools/ci-local.sh), so this had to land somewhere regardless.

dtourolle	89c4ff1820	Store what the model found, so a reopened photograph keeps its masks ... A subject or category layer was written to the sidecar as identity alone — which run, which instance, which category — on the reasoning that the pixels are reproducible by running the same model over the same image. They are, but only by *running the model*, and nothing runs one except a photographer pressing "find subjects". So on every path that did not already have a run in memory the layer resolved to no coverage, `MaskPass::render` logged "has no distance field; skipping", and the adjustment was silently absent: - reopening an edited photograph rendered it without its local adjustments, and then saved that state back on the way out; - a batch export from the grid could not have them at any point, because `render_from_library` opens a session, applies a version and renders, and there is no model anywhere on that path. Three hundred files written without the edits their photographer made, over a log warning. Neither failure announced itself. The generated shader still emits the layer's block and the empty placeholder multiplies it by zero, so the result is a well-formed frame that is simply missing an edit — `mask_is_stale` already named the state and called it "not stale, just unrenderable". The coverage now travels in the file, as one `coverage = w h levels payload` line at the end of the layer's block. Two levels, and that is not a compromise. The model hands out a byte per pixel but `Shaped::build` measures its distance field from `coverage >= 128` and throws the shoulder away on the first line; everything soft about the rendered edge comes afterwards from the layer's feather and falloff, which are read off the distance. So one bit per pixel is not an approximation of what the model said — it is exactly the part of it that reaches a pixel, and the stored mask renders the identical frame. Storing all 256 levels would have stored 1.7 MB of bilinear interpolation to reconstruct a predicate, and would not even have compressed: a model mask is a bilinear upsample of a coarse grid, so almost no two adjacent bytes are alike. Measured on a simulated sky and a simulated figure at 1600x1067, against 1.71 MB raw: 4.0 kB and 6.5 kB at two levels, 46 kB and 76 kB at sixteen, 835 kB and 1.43 MB at all 256. The level count is still written into the line, so a later build that finds a use for the shoulder can write sixteen and this one will read them rather than misreading a stream of lengths as pairs. The coder is hand-rolled — run-length pairs in a base-64 varint — because `dr-pipeline` links nothing, which is the property that lets the descriptor and codegen logic be tested without a device. `flate2` would have been fewer lines and a dependency in the one crate that has none. Where it lives matters more than how it is coded. The raster sits on `MaskLayer` beside the source, not inside `MaskSource::Subject`: the source is *identity*, which is what makes it diff as a handful of numbers and merge per field under FR-NC-9, and a raster in there would have given the merge a binary blob to arbitrate. It takes no part in `MaskLayer`'s equality for the same reason — a device that has run the model and one that has not hold the same edit, and counting the difference would raise a conflict over a cache and let `remote_wins` answer it by discarding the only copy of the pixels. Encoding happens in `masks_for_storage`, on the save path, rather than in `ensure_subject_fields` where every coverage already funnels through. `ensure_subject_fields` runs on a drag — dilating a mask with a compound morphology rebuilds the field every frame — and encoding a megapixel raster per frame is the kind of work NFR-P5 exists to keep off a gesture. Saving happens once, when the photograph stops being the open one, and already costs a network round trip. Version skew holds both ways. A file with no `coverage` line reads exactly as it did before, which is a layer that needs the model run; an unreadable one costs the pixels and not the layer, because the layer is the edit and the raster is a cache of it. An old build reading a new file drops the key it does not understand, which costs a model run and no work. And a payload that will not compress is refused rather than truncated: a checkerboard would encode to twice the raster it came from, so past 64 kB nothing is stored and the behaviour falls back to what it was — half a mask would render as a mask that is confidently wrong, which is the failure that tells nobody.	2026-08-30 21:28:54 +02:00
dtourolle	6acc98baad	Carry the photograph's header into an export made from develop ... The same file exported from the library grid kept its camera, its lens, its capture date and its rights statement. Exported from the develop button it kept none of them, and `{date}` in a filename template resolved to nothing at all. Two buttons, one photograph, two different files -- and the develop one was the version the photographer had just finished working on. A session now remembers the header it was opened from, and `open_session` takes that header rather than the orientation read out of it, so a photograph cannot be opened for editing without saying which file it came from. `render_open_frame` clones it onto `Source::Rendered`; both arms of `export_one` -- the worker's own decode and the frame handed over already rendered -- turn a header into a `{date}` and a `SourceMetadata` through the same function, so the two paths cannot come to different readings of one file. What of it actually reaches the exported bytes is still decided inside `dr-export` from the settings, which is what keeps the location-stripping option working here rather than giving it a second implementation to disagree with. The alternative was to hang the metadata on `Source::Rendered` alone and keep it beside the session in the interface. That touches less, but it makes the header and the pixels two cells to hold in step across the six places an image is opened, replaced or fails to open, and the failure mode of getting that pairing wrong is not a missing tag: it is one photograph exported under another's byline and coordinates, silently. Kept on the session, the two travel together or not at all. The header is stored decoded rather than transcribed at open time, deliberately. `dr-export` argues that source metadata is a parameter and not a field on `Frame`, because two exports of one frame may legitimately disclose different amounts; by the same reasoning a session may remember where its pixels came from without that being a decision about what to publish, and the allowlist that decides remains the single function in `export.rs`. A file with no header is left with none -- an empty `{date}` and nothing for the encoder to copy -- rather than today's date standing in for a capture time nobody recorded.	2026-08-30 21:28:31 +02:00
dtourolleandClaude Opus 5	353382c07f	Hand the photographer's place between devices ... A place recorded on the tablet should be where the desktop opens. Exchanged through `.darkroom-derived/place.json`, beside the thumbnail shards and the catalog snapshot. Newest timestamp wins outright: unlike the catalog this is replaced rather than merged, because two devices cannot both be where the photographer is and so there is nothing of theirs inside ours to preserve. It still refuses to upload over a copy it could not read, for a smaller version of the reason `sync_catalog` does: a record we have not compared against may be the newer one, and overwriting it would move the other device's photographer without ever having seen where they were. Last in the pass, and its failures are logged rather than reported. Everything else in that folder is *derived* -- a faster way to learn what the device could work out for itself -- so losing it costs time. A place is a fact only the other device knew, and losing it costs a scroll. A sync that ran out of connectivity should spend what it had on the shards. The full pass runs after a thumbnail sweep or when Sync is pressed, neither of which happens on an ordinary launch -- so a handover would arrive one launch late, which is one too many for a feature whose whole claim is picking up where you stopped. `spawn_place_fetch` is the small half: one GET of a few hundred bytes, started beside the scan. And it can still be refused. A handover is welcome on the way in and unwelcome once the photographer has started: a grid that jumped elsewhere mid-scroll because a round trip finally landed would have lost their place to the feature meant to keep it. Any scroll, scrub, scope change, filter or opened photograph closes the latch, and a record arriving after that is written to disk and takes effect next launch.

dtourolleandClaude Opus 5	d44bffa4a8	Remember where the photographer was ... Opening the application was always a fresh arrival at the beginning of the library, whatever you had been doing when you closed it. What is written down is the view, the scope, the rating filter and the photograph on screen -- the open one in develop, the first visible one in the grid. Not just a scroll position: a position without the filter that produced it names a row of a list that no longer exists. Restoring them has an order for the same reason -- scope, then filter, then position, then the view -- because each step changes what an ordinal *means*. Addressed by remote path and collection UUID, never by an ordinal or a row id. `images.id` and `collections.id` are local to one catalog, and a grid ordinal is local to one ordering; a record naming either would land somewhere arbitrary on a second device and after any filter change on this one. Where the ordinal is needed, `library::ordinal_of_path` computes it through the grid's own `ORDER BY`, taken verbatim by a window function rather than spelled a second time as an inequality -- which is the mistake `grid_order_for` already warns about, and which a manually ordered collection would make unreadable. Every failure degrades rather than reports. A collection this device has not merged leaves the scope at the whole library; a photograph that has since been deleted falls back to when it was taken, which puts the grid in the right week; a torn file yields no place and the library opens at the top. Reopening develop is the one thing that requires an exact match, because a canvas on a path that no longer resolves is a filename over an empty frame. The record lives in `dr-types` beside `Settings` and the store lives here beside `SettingsStore`, for the reason `dr-types`' manifest gives: a JSON serialiser in `core/` would be paid for by every crate there. Two files and two lifetimes, though -- resetting preferences must not forget where you were. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-30 20:39:50 +02:00
dtourolleandClaude Opus 5	8bf5e13faf	Centre the photo roll on the frame it opens with ... The roll brought the open photograph into view by the shortest move, which is right for stepping along it and wrong for the first look: a frame near either end of the loaded window arrived hard against an edge, with nothing on that side to give it any context. It now centres on the first settle of a develop session and steps minimally after that. A one-shot request that the strip itself clears -- the only thing that knows the request has been honoured is the code honouring it -- rather than something recomputed on creation, because the strip is created far more often than a session begins: leaving develop for Settings and coming back rebuilds it, and re-centring then would undo a roll the user had scrolled by hand. Raised on the two ways into develop from the grid, and not on a pick along the roll, which is a step within a session rather than the start of one. Centring is clamped to the ends: the third photograph of a window cannot be centred without scrolling empty space in beside it, and a strip that begins with a gap reads as broken rather than as centred.

dtourolleandClaude Opus 5	0ff1e01ec3	Come back from develop on the photograph you were editing ... Leaving develop returned to where the *grid* was, which after a walk along the photo roll can be a thousand rows from the frame you had just finished. So the one photograph you were certainly interested in was the one the grid came back without. Two positions, and the rule is not to pick one of them. The grid seeks to the remembered position, then reveals the keyboard cursor -- which is now put on the open photograph, and which moves the viewport as little as will bring its row into view. A frame inside the remembered screenful moves nothing at all; one outside it scrolls exactly far enough. One rule, both behaviours. The cursor rather than the selection, deliberately: `place_cursor` also rewrites the selection, and a set of forty photographs assembled in the grid must survive having one of them opened. `reveal()` now also runs on the grid's `init`, since `cursor-row` is initialised rather than changed when the subtree is rebuilt and no handler would otherwise fire. Both it and the roll's centring defer while the element has no height yet -- `init` runs before layout, where a height of zero makes every row look off screen -- and a latch brings the first real height back to the cursor without letting every later resize haul the viewport around. The capture-time marker follows the same move, for the same reason: `load_window` rebuilds the axis only when the scope, the filter or the total has changed, and none of them has. It is the same library seen from a different row. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-30 20:35:23 +02:00
dtourolleandClaude Opus 5	53dc2d171e	Say where the grid is on the capture-time axis from the first frame ... The sidebar's marker rested greyed at mid-track until the first scroll or scrub. The reasoning was that anchoring it would imply a choice the user had not made -- but that reads the marker as reporting an intention, and it does not. The sidebar's whole claim is to say *when* you are, and that is known from the first frame: the grid is at the top of the library, or wherever it was last left. So a launch opened with the marker halfway down an axis whose visible photographs were all from the wrong end of it. Dimmed rather than absent, which made it look like a reading rather than the absence of one. Seeded in `refresh_timeline` -- the one place that decides what the marker says, and the one that runs on every route which builds the axis -- and only when nothing has claimed it, so a scroll or a scrub still speaks for itself.

dtourolleandClaude Opus 5	eed27eb36d	Keep the grid's place when another screen covers it ... Opening Settings, Import or People and coming back landed at the top of the library however deep in it you had been. The grid is gated on an `if` in the markup, so every route away from it destroys the subtree and rebuilds it. A Flickable being destroyed passes its viewport through zero on the way out, and that reaches `on_library_scrolled` looking exactly like the user having flung the grid to the top. The handler already guarded against it -- but on `show-library`, which means "the library rather than develop" and stays true while any of those four screens replaces the window. So the guard covered the develop route and none of the other three: `resume_at` was overwritten with 0 on the way out, and the position was gone before anything could restore it. The condition the `if` is actually spelled with is now computed once, in `app.slint`, and Rust reads that. The two cannot drift apart again because there is only one of them. That fixes the overwrite. The second half is that nothing replayed the position on the way back in: `on_back_to_library` does it by hand, and Settings, Import, People and the launch screen do not go through it. Rather than teaching three more modules to call it, `scroll-to` is now kept current on every scroll. It is read by `seek()`, which runs on a token change and on `init`, so writing it without bumping the token cannot move the grid on screen -- and is exactly what the next grid reads when it is built.

dtourolleandClaude Opus 5	4dc954f01a	Take the photo roll's grab band off the buttons that end a mode ... "Done Cropping", "Done Repairing", "Done Masking" and "Fit" float over the foot of the canvas. So does the photo roll's swipe handler, and a gesture handler is not a layout box — it is an input surface. A press inside one is delayed, then offered to that handler's own children and to nothing else: `input_event_filter_before_children` returns `DelayForwarding`, which aborts the hit-test traversal outright, and the replay afterwards visits only the handler's subtree. Everything behind it is never asked, hover included. The band was `strip-height + reach` — 136px along the bottom — whether the roll was out or away. So the button that ends a mode was drawn, was lit, and did nothing for as long as a library was open, which is the whole time anybody is developing from one. The tool rail kept working because it is a sibling of the canvas rather than behind the roll, which is exactly why this looked like two dead buttons rather than a dead region. The band now goes where the roll goes. The handler carries the strip instead of standing still while the strip animates inside it: closed, only `reach` is on screen and the rest hangs below the window where nothing can press it; open, it still covers the thumbnails, which is what lets a swipe down anywhere across them put the roll away. The 180ms travel moved from the strip onto the handler, so the drawn positions in both states are what they were. The controls are then positioned against that band rather than against the bottom of the canvas, and ride up with the strip when it comes out. Reordering them in front of the roll would have been the other fix, and it is the wrong one — the band would become the thing that cannot be reached, and a gesture nobody can start is worse than a button with a second way out. `roll-strip` and `roll-reach` are tokens now, because two files have to agree on where that band is for either of them to keep out of it. The bottom of the photograph comes back with it: the crop's lower handles and a repair placed near the bottom edge were inside the same 136px and had the same fault.

dtourolleandClaude Opus 5	3d248cfb79	Export the photograph, not the canvas ... Zooming the develop view changed the exported file. `Framing::view` is kept out of the sidecar, out of `is_active` and out of `output_size` precisely so that it cannot — but those exclusions keep it out of the *edit*, and an export is a *render*. `visible_rect` deliberately folds the view into the single rect the fused shader's prologue samples, so `render_for_export` inherited it: at 4:1 it wrote the middle of the frame, magnified to fill the file at the full output size, with the detail kernels scaled four times over because `render_scale` folds the view in as well. `render_thumbnail` did the same to the grid. `render_uncropped` already suspends the view for this exact reason, so the fix is its pattern: one `render_the_file` that both file-producing paths go through, composing inside the suspension since the view reaches the shader as a uniform baked at composition time. Restored whatever happens — leaving the graph un-zoomed after a failed export would throw away where the photographer was looking. Nothing caught it because the guard checked the wrong things. `zooming_does_not_change_the_exported_image` asserted the output size and the crop; both held perfectly throughout. Renamed to `zooming_does_not_change_the_size_or_the_crop`, which is what it tests, and the pixels are now guarded where pixels exist. The new test uses a ramp rather than quadrants deliberately: a four-quadrant frame is self-similar under a centred zoom, and the first version of this test passed against the bug because of it. Traces FR-EXP-9, which asks for the full-quality pipeline "regardless of what the display was showing". Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-30 19:41:30 +02:00
dtourolleandClaude Opus 5	a1e361e35a	Measure the native path against the one it replaces ... Everything argued for this change so far was read out of a catalog after the fact: crop_px across 18,671 faces the old code had already stored. That is evidence about what the previous implementation did. It is not evidence that the new one does better, and the difference matters because a landmark left in the detector's coordinates, or a box filter with an off-by-one in its source span, would both produce faces that look entirely plausible until somebody counted the pixels behind them. So examples/face_native.rs renders one file and indexes it twice, native and from a 1024 proxy, changing nothing else. Fourteen originals from the reference library, 5472x3648 CR2 and DNG: native 9 faces, mean crop 287px 1024 proxy 5 faces, mean crop 75px Crops 3.8x larger, and across the line that decides whether the crop is photographed or interpolated: 75px is below ALIGNED_EDGE, so the proxy path was upsampling into the embedder on average where this one downsamples into it. Fourteen images and nine faces is enough to show a direction and to catch a wrong scaling; §7b says so rather than quoting the ratio as a library-wide figure. It also corrects something §7b asserted two commits ago. I wrote that detector input resolution cannot affect recall, because §4.1 letterboxes everything to 640. Native found nine faces to the proxy's five, including four on files where the proxy found none, so it plainly can. The two paths differ in their resampling as well as their size, and this experiment does not separate those, so §7b now records the result as evidence for the double-resampling hypothesis rather than as its proof. M4 still owns settling it. The audit-summary test went stale when the ready/to-fetch split was collapsed and is updated to assert the single number, including that the old wording is gone.

dtourolleandClaude Opus 5	4af3b93dfa	Index faces from the native render, not from a preview of it ... Implements the FR-CULL-8 written two commits ago. The sweep fetched the JPEG preview embedded in each RAW and used that one buffer for both detection and the crop; it now fetches the original, renders it through the same path export uses, reduces that for the detector, and warps the crop back out of the native frame. Three pieces, and each exists for a reason worth stating. dr_face::Pixels lets the warp sample 8-bit RGBA directly. A 24 MP native frame is 96 MB as RGBA and 288 MB converted to the f32 RGB align.rs was written against, and the warp reads about forty thousand pixels out of it. Converting the whole frame to sample 0.2% of it is NFR-RES-2's budget spent on a copy, per image, for a whole library. The variant costs one branch per sample and a test asserts both layouts produce identical crops. The detector gets a box-filtered reduction to 1600px, not the native frame and not a point-sampled one. Averaging rather than sampling because the detector's job is finding small faces and decimation is precisely the operation that removes them: at 4x, fifteen of every sixteen pixels are discarded and a 40px face survives or not depending on where it falls relative to the sample grid. 1600 rather than 640 leaves the letterbox a mild 2.5x rather than a 9x, and bounds the f32 buffer at 20 MB. Landmarks come back in the reduction's coordinates and are scaled to native in one place before any crop pixel is read. This is the failure mode that would not announce itself -- unscaled landmarks put every crop near the top-left corner, which yields faces of something else, cleanly embedded and confidently clustered. The sweep fetches SWEEP_LANES-wide and renders sequentially. Not a placeholder for a parallel version: there is one GPU, so concurrent renders queue on it regardless, and each materialises a native frame. Overlapping them would multiply the one allocation that threatens the memory budget while buying parallelism that does not exist. The chunk drops from 96 to 6 for the same reason -- 96 held 8 MB previews, this holds whole RAWs. The stored edit is deliberately not applied, which is where this departs from export::render_from_library. Face geometry is normalised to the frame, so indexing a cropped render would record boxes against a frame that changes whenever the user changes their mind, and every stored box would quietly become wrong. Orientation is applied: that is a fact about the file rather than an edit. examples/face_native.rs renders one file and indexes it both ways, so the claim behind all of this can be checked against photographs rather than re-read out of the catalog it came from.

dtourolleandClaude Opus 5	9ddc1273c0	Make a sweep that fails everything say so ... A run over 169 images failed all 169, in fourteen seconds, and reported "0 face(s) in 0 image(s)" -- the same sentence a run that indexed nothing because there was nothing to index produces. Three separate places dropped the information on its way to the screen. The progress count only moved on success. FaceSweepMessage had no failure variant at all, so a pass where every image failed sat at 0/169 from the first tick to the last: the receiver was told the total, told nothing, and told the pass had ended. That is indistinguishable from a hung job, and it is what it was taken for. Finished already carried a failed count and identity_ui matched it with `Finished { .. }`, throwing the number away and printing the tidy success line regardless. And the reason each image failed was logged at debug, which is off, so 169 consecutive failures left no trace of why anywhere. Failed { images } now carries the count back per lane batch, the progress counter advances on it, and both the running status line and the finishing activity row say how many could not be read. A batch rather than one message per image because failures come back lane-sized and the useful number is how many. Also renames the store sweep's guard to MIN_CROP_EDGE with the rest of that constant's move, since the two touch the same lines.

dtourolleandClaude Opus 5	e7b526c550	Specify face indexing at native resolution, and say what the proxy cost ... FR-CULL-8 said detection runs against the thumbnail or proxy tier and never a full decode, and faces.md §5 said the aligned crop is sampled from that same proxy. Both are wrong in the same place: they treat detection and cropping as one resolution problem when they are two, with opposite answers. Detection does not care. §4.1 fixes the graph's input at 640x640 and letterboxes whatever arrives, so a face filling 2% of the frame reaches the model at 12px whether the buffer handed over is 1024px or 6000px. Every pixel above the detector's own input is discarded before inference. The crop cares about nothing else. §5's warp produces the fixed 112x112 ArcFace sees, so source resolution converts directly into whether those 112 pixels were photographed or interpolated. Reading crop_px across the 18,671 faces the proxy-tier implementation stored: 47.3% were upsampled to reach the embedder, 314 of them by more than 2x, the smallest from 34 source pixels. An upsampled crop does not fail loudly -- it yields a confident embedding of detail that was never there, and the damage appears three stages later as clusters that will not separate. So FR-CULL-8 now specifies four stages with the resolutions named separately: render native through FR-EXP-9's pipeline, downscale for the detector, map boxes and landmarks back to native, crop and align from the native render. The affordability the old rule bought is met instead by when the pass runs -- background, preempted, resumable -- and the requirement says plainly what it now costs on a remote library: the original rather than FR-NC-3's byte range, 412 GB across the reference library's 19,107 images, so a whole-library pass is a transfer under FR-NC-6 rather than something that may start on its own. MIN_CROP_EDGE replaces the MIN_DETECT_EDGE this branch briefly had. Same number, guarding the quantity that turned out to matter. faces.md §7b records both measurements, and marks the second as unexplained rather than dressing it as a finding. Grouped by the buffer detection ran against, faces per image was 0.078 at 1024 or below and 1.82 at 2048 or better, controlled for file type and size. That gap is real and reproducible and I cannot account for it, because the letterbox above says detector input should not matter. M4 is where it gets settled. The crop measurement does not depend on it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-30 19:41:20 +02:00
dtourolleandClaude Opus 5	144d2e4e84	Revert the detection floor: it guards the wrong resolution ... Reverts 53f7cdf and e92d22d. The floor those added sat on Detector::detect, refusing any buffer under 1025px on the reasoning that a small buffer finds no faces. That reasoning does not survive §4.1: the detector letterboxes every input to 640x640, so a face occupying 2% of the frame presents at 12px to the model whether it is handed a 1024px buffer or a 6000px one. Detector input is precisely the quantity that does not matter. Worse than merely useless, it blocks the design FR-CULL-8 now specifies, where the detector is deliberately fed a downscale and the crop is taken from the native render. A guard on detect() rejects exactly that call. What the measurement actually supports is a floor on the *crop* source, which is where resolution converts into embedding quality, and which faces.crop_px already records: 47% of the reference library's faces were upsampled to reach 112x112. That floor is a separate change against the native-resolution path and does not belong on the detector. The 23x faces-per-image gap by source_edge that motivated the original commit is kept in faces.md §7b, restated as the unexplained observation it is rather than the causal claim it was written as. V12 stands: those runs cropped at 1024 whatever detection did, and that is reason enough to look at them again.

dtourolleandClaude Opus 5	41c655c176	Stop the local-store pass pretending it can still index ... spawn_store_face_sweep detects on what the thumbnail store holds, and the store's largest tier is FACE_TIER -- 1024, which the floor now refuses. Left alone it would list every outstanding image, decode every proxy it had, and report every single one as failed: twenty thousand refusals all saying the same thing, with the real explanation buried at debug level. There is no repair available inside this pass. It has no larger tier to read; the pixels the detector needs have to come off the server, which is spawn_face_sweep's job and always was. So the honest behaviour is to check the tier against the floor once, say plainly which pass to use instead, and stop. It is only reached from examples/face_index.rs, so this costs the tool its --run mode and no shipped behaviour. FACE_TIER keeps its value and loses its meaning. It is now the tier a stored crop is *cut from*, which 1024 is entirely adequate for -- the face has already been located and the crop only has to be looked at -- and no longer the tier faces are *found* on, which is the thing that was returning 0.078 faces per image. IndexAudit's ready/awaiting_proxy split goes the same way. It existed because one of the two passes could only do images that already had a proxy; now that detection refuses that proxy's size, both halves cost the same fetch, and a status line reading "169 ready to index" implies a distinction that no longer decides anything. One number. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-30 19:41:04 +02:00
dtourolleandClaude Opus 5	d0ebc9f571	Count the same images in the progress figure that the sweeps index ... The Identity screen said 4,593 images were left to index and stayed there for hours across repeated runs, which is what a stuck job looks like. It was not stuck. 4,424 of those 4,593 are shadowed -- the JPEG half of a RAW+JPEG pair -- and no sweep will ever index one, because every work list is built on VISIBLE, which excludes them. They are not separate photographs and the grid does not show them either. But faces::coverage counted them: its denominator was "images WHERE trashed_at IS NULL", with no shadowed_by clause. So the outstanding figure had a floor of 4,424 that no amount of work could bring down, and Coverage::is_complete could never once return true no matter how completely the library had been indexed. A progress number that cannot reach its own target is worse than no progress number. The fix is to count the population the sweeps actually draw from, in all three places that were describing it differently: coverage's denominator and its indexed join, and audit's split of the outstanding set, which had the same gap and fed the same status line. On the reference library the denominator goes from 23,531 to 19,107 and outstanding from 4,593 to 169 -- the second of which is a number the user can watch go down, and which turns out to be a real and separate fetch failure worth chasing.

dtourolleandClaude Opus 5	6783d0c723	Settle the images whose best preview is under the floor ... The floor introduces a state the sweep had no arm for. An image whose largest embedded preview is genuinely smaller than 1025px now comes back from index_preview as an error, lands in the generic Err arm, and is counted as failed -- which means no face_index row, which means it is still outstanding, which means the next sweep fetches exactly the same bytes and refuses them again. For ever, on every run, at one range request each. The previous behaviour was wrong but at least terminated; this would not. So ProxyTooSmall gets its own arm, and it records a marker at the true edge rather than nothing. That is the difference between "we looked and found nothing" -- which would be a lie, since nothing was looked at -- and "this was examined at 900px, which is the best this file has". The first is unrecoverable; the second is a fact source_edge was added to carry, and a later floor or a bigger proxy can select on it deliberately the way V12 just did. Counted separately from failures all the way up, because they are not failures and reading them as such would misdescribe a library of small scans as a broken network. The summary line says how many and why. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-30 19:41:04 +02:00
dtourolleandClaude Opus 5	0a6509de93	Forget the face runs made on proxies too small to see a face ... The floor added in the previous commit stops this happening again; it does nothing about the 1,824 images in the reference library that already carry a face_index row written against a proxy of 1024 or less. Those rows are why the damage is permanent rather than merely past. The work list is "images with no row for this model", so an image examined against a 1024px proxy -- 0.078 faces per image, nine in ten finding nothing -- is indistinguishable from one examined properly, and no later pass will ever offer it to the detector again. V12 deletes exactly those markers, and nothing else. The faces those runs did find stay in place and keep drawing the People screen until a better pass replaces them, and record_detections re-attaches the user's confirmed names across that replacement by box overlap, so a library somebody has spent an evening naming does not lose that evening. The cost is a re-fetch of the affected images. Deleting the marker rather than teaching the work-list query to select on source_edge, which was the other option and is worse. A standing `source_edge < floor` predicate never lets go: an image whose largest embedded preview is genuinely smaller than the floor would be re-fetched on every sweep for ever, because the next pass cannot do any better than the last one did. A one-off deletion gives each affected image exactly one more attempt through the good path and then lets the ordinary "has a row" rule settle it. The threshold is written out in the SQL instead of referring to dr_face::MIN_DETECT_EDGE. A migration has to keep meaning what it meant when it ran; binding it to a constant someone may raise later would quietly change what an old catalog gets migrated to.

dtourolleandClaude Opus 5	1d800d56b0	Refuse to detect faces on a proxy too small to find one ... Detection was run on whatever proxy the caller happened to have. A small one does not fail -- the image is letterboxed into the detector's 640px input at any size -- so it comes back with almost nothing, and the caller then writes a face_index row saying the photograph was examined. That row is the damage. Nothing distinguishes it from "examined properly, no faces in this one", so the image is never looked at again. The measurement, on the reference library of 23,531 images. Runs against a 1024-edge proxy: 0.078 faces per image, 90% of them finding nothing at all. Runs against 2048 or better: 1.82. To rule out the obvious objection that small proxies just come from small photographs, the same comparison restricted to DNGs -- 1,592 of them averaging 21 MB against 7,724 averaging 23 MB, so the same kind of file in the same library -- gives 0.078 against 1.82 again. Twenty-three fold, on identical source material, identical weights, identical options. So the floor goes in the detector rather than in either sweep, because both of them, the example tool and any future job handler are equally entitled to get this wrong, and there is one place that sees every attempt. It is 1025, not 1024, and the odd-looking number is the point: 1024 is exactly ThumbSize::Large, the tier proxies are stored at and the tier one of the two sweeps was detecting on. A floor that admitted 1024 would admit precisely the population this exists to exclude. Written as a minimum rather than a maximum so the test at each call site is `edge < MIN_DETECT_EDGE` with no boundary left to get wrong. ProxyTooSmall is its own error variant rather than an empty result because the caller has to tell it apart from a failure: nothing is wrong with the image or the model, and the answer is to go and find better pixels, not to retry these ones.

dtourolleandClaude Opus 5	7981718d83	Time the phases of a launch, because the tablet has no profiler ... Two things are now off the launch path and the rest of it is unmeasured. There is no way to attach a profiler to an Android launch, and the window that matters — from `android_main` to the first `poll_events` — is over before anything on the device can be asked a question about it. So a line in the log file is the only measurement anybody gets. Three of them: the GPU open, the window build, and the total to the event loop. The last is the one that matters, because it is the figure the input dispatcher is counting against — anything approaching five seconds there is the next ANR whatever the phases above it say. The GPU open is timed rather than moved. It is a Vulkan instance, an adapter enumeration and a device request, and on the desktop it cannot be deferred at all: it selects the Slint backend, and creating a window selects one for us. On Android it could be, because nothing shares that device with the compositor (TD-1) — but "could be deferred" is not "costs enough to be worth deferring", and there is no number yet that says which. This is the line that will produce one. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-30 18:41:34 +02:00
dtourolleandClaude Opus 5	d48e9f6033	Open the catalog on a worker, so a launch is not a page-by-page read ... The second thing standing between `android_main` and the first `poll_events`, and the one that grows with the library rather than with the APK. `library_ui::open` called `show_catalog_now`, which called `Catalog::open_verified`. That runs `PRAGMA quick_check`, which reads every page of the database, and then `Catalog::open`, which takes a full SQLite backup of the file before a migration and rewrites its structure afterwards. On a 50,000-image library that is tens of megabytes of I/O on a tablet's flash, and it happened before the window had painted anything — so on Android it was counted against the five seconds the input dispatcher allows, and on the desktop it was a launch that sat on a blank window. `dr_catalog::recovery`'s own module documentation says the check is affordable "at startup, where a failure has a user in front of it who can answer a question". That was the intent and it was not true: there was no interface yet in which to ask. Now there is, because the open happens on a worker and the answer arrives on a channel drained by a timer — the same shape the scan, the thumbnails and the login already use. The gate the synchronous call provided is kept, and is the reason the scan moved with it. `Catalog::open` succeeds on a damaged file whose header survived, so a scan running beside an unanswered recovery question writes ETags and image rows into damaged pages and turns a catalog that had a backup into one where the backup is the only copy left. So the scan now starts from the drain, on the two answers that permit it, and not at all on `Corrupt`. `library-scanning` stays true throughout, which hides the Rescan button and stops the gate being merely advisory. What the user sees while it runs is a third empty state. The grid already refused to conflate "still scanning" with "scanned, found nothing"; "opening the library" is a third answer and it gets its own sentence, because a grid saying "Scanning…" while nothing is on the network is the same kind of lie the other two were separated to avoid. `show_catalog_now` stays, unchanged and blocking, for `recovery_ui`. That call site has the event loop running, has just replaced the file under a `forget_catalog`, and has `recovery-busy` on screen — the same reasoning `recovery_ui::answer` already gives for doing its file copy in place. The part both paths share is now `adopt_catalog`. One consequence worth naming: the cache-usage figure on the settings page was read at startup from a catalog that is no longer open by then. It moves to the page's `on_open` closure, beside the face coverage, which is read there for exactly the same reason — it is only ever looked at while that page is on screen.

dtourolleandClaude Opus 5	1c5849ebe8	Unpack the bundled models on a worker, not on the way to the first frame ... Launching v0.10.0 on the tablet produces an ANR: "Waited 5000ms for MotionEvent", 5,827 ms on one input sequence, over a window that has never painted. The app recovers and sits at 0% afterwards, so it is a startup cost rather than a hang. The structural fact behind it is that `android_main` runs with the activity's input channel unserviced. Nothing drains it until Slint reaches `poll_events`, and Slint does not reach `poll_events` until `dr_ui::run` calls `window.run()` on its last line. Every millisecond before that is a millisecond the input dispatcher waits on, so five thousand of them is an ANR whatever the work happens to be. The largest single piece of that work was here. `install_bundled_models` copies 41 MB on the first launch after an install — 24.9 MB of scene model, 13.6 MB of embedder, 2.5 MB of detector — each read whole out of the APK into a `Vec` and written to `/data`, in a loop, on that thread. v0.10.0 is the release that added the scene model, which is 60% of that total, and it is the release the ANR appeared in. The 8,010 minor faults in the report are about what 41 MB of freshly touched pages costs. So it moves to a detached thread and the function returns as soon as the thread is running. Nothing on the launch path wanted the result: the only two things that read these files are the People screen and the scene tab, both of which are reached by hand, minutes later, from workers of their own. What that costs is a window in which a model looks absent. `library::face_models` and `library::scene_model` decide availability on `is_file()`, so during the copy both report their feature unavailable — which is the same answer they give a build shipping no weights at all, the ordinary case both were written around. Briefly pessimistic rather than wrong, and the temporary-name-then-rename that was already there is what keeps it from being worse than that: a lookup never sees a half-written file, only an absent one. Both call sites now say so. A completion line reports the bytes copied and the milliseconds taken, including when it is zero, so the second launch after an install can be told from the first in a log rather than by inference.

dtourolleandClaude Opus 5	4efab496c2	Put the refinement on a slider, per layer ... The evidence was being gathered and spent immediately at one strictness nobody could see or change. This makes it a control. `MaskLayer::refine` is shaping, like the feather, and it lives on the layer for the layer's reason: two layers may sit on the same category and want different amounts of it, and the model ran once for both. ## What the segmentation now stores `CategorySummary` keeps the **coarse** mask and the `Refinement` beside it, rather than a refined mask. That is what gives the control an off position that is bit-for-bit the model's own weighting, and what stops a strictness change from needing the model again. `category_mask_at` borrows at zero and wherever no refinement could be fitted, so a layer nobody has touched costs nothing over the old path. The fit moved to the far side of the orientation permutation. The verdict is a per-pixel field over the same grid as the mask it gates, so fitting it upright would mean permuting a proxy-sized buffer afterwards to match — a second rotation, and a second chance to get one wrong. One logit cell is the same number of pixels either way: the letterbox scales by the longer edge and a permutation does not change which edge that is. The two frames became a `Frames` struct rather than six parameters. This function reads the picture twice for opposite purposes — the model needs it upright or it recognises far less, the refinement needs the sensor's grid — and a transposed pair produces a plausible mask over slightly the wrong pixels, which is the failure this module is most prone to. ## It rebuilds the field, and the signature says so `refine` is mixed into `subject_signature`. Unlike a feather, which is read off a field that is already correct, this changes which pixels are in the mask at all — so it changes the coverage the field is measured from. Omitting it is the bug where the slider moves and nothing happens until some unrelated control invalidates the cache. That puts it in the same cost class as a close or an open, which is why the row takes `SliderRow::changed` — already once-per-gesture, since that row takes `SliderTrack`'s `committed` internally — rather than a live stream. The slider is offered only where there is something to move: a category source, *and* a refinement the frame actually gave enough to fit. A control that moves and does nothing is worse than an absent one. ## Two defaults that are deliberately different A layer added from the panel starts at 4.0, because a category's edges are twenty proxy pixels wide before anything is done to them and a photographer adding a sky mask wants the sky rather than the sky plus every chimney in it. A layer read from a sidecar with no `refine` key starts at **zero**. A file written before this control existed has to render as it did then, and a default of 4 on absence would quietly re-grade every stored category mask in the catalogue. `a_categorys_refine_strictness_survives_and_defaults_off` holds both halves, and `an_out_of_range_refine_is_clamped` holds the file to the scale — past the top of it every colour fails and the mask deletes itself, which reads as lost work rather than as a bad file. `MAX_REFINE` is dr-pipeline's own constant mirroring `dr_segment::STRICTNESS_MAX`, following `Falloff` and `Morphology`: this crate holds the description of an edit and must not depend on the crate that runs a model. dr-ui is where the two meet, and the only place that converts.

dtourolleandClaude Opus 5	f87bf6ebc0	Charge a colour mode for its rarity, and keep the verdict ... The refinement worked and could not be controlled. Pruning modes below a share threshold made the flag's removal a *discrete* event: below the line its Mahalanobis distance was enormous and nothing rescued it, above the line it sat at zero and nothing removed it. A control over that would appear dead through most of its travel and then start eating sky. So the prune is gone. A mode is charged `−ln(share × k)` nats, floored at zero, and that cost enters both tests — doubled in the chi-square, which is a squared distance, and directly in the log density. Rarity becomes a distance rather than a threshold, and the things a photographer wants to remove separate along it. Measured on the synthetic frame the tests build: a flag holding 1.6% of the sky is more than half gone by **2.95 nats** and a cloud bank holding a third of it survives to **5.75**. The whole interval between them is somewhere a control can sit. `the_flag_goes_before_the_cloud_does` pins the ordering, which is the property that makes one slider worth offering at all. Measured against an even split rather than against one, so raising `clusters` describes a category more finely without making every colour in it look rarer. Floored at zero so a dominant mode earns no *discount* — a bonus there would let the commonest colour outvote a bad chi-square, which is the one direction this must not bend. `Refinement` holds the per-pixel verdict, quantised to a byte over ±16 nats — an eighth of a nat per step, far finer than the narrowest transition the gate can be asked for, and the same size as the coverage buffer it sits beside. `apply` is then a smoothstep, and the model is never consulted again. That is `distance.rs`'s arrangement deliberately: there a signed distance field is computed once and feather, grow and shrink become arithmetic on it, "which is what makes those live controls rather than ones that stall on every drag". Same shape, different field. The blur moved with it, from the gate to the verdict. Smoothing the evidence rather than the decision means it is paid for once in `compute` instead of on every frame of a drag, and it is the better thing to smooth in any case. `apply` at `STRICTNESS_OFF` returns the weights untouched without reading the verdict at all. A control whose off position is *very nearly* the unrefined mask cannot answer "is this helping"; one whose off position is the unrefined mask can. `strictness_zero_changes_nothing` holds it to that, and `strictness_is_monotonic` holds the rest of the travel to only ever removing more — a slider that gave weight back partway up would be one whose direction nobody could predict. The synthetic sky is smooth enough to sit on `VARIANCE_FLOOR`, where a real one has noise and therefore a real spread, which moves every crossing down together. The ordering survives that; the placement is a calibration. Which is the honest argument for a control rather than a constant, and why the default sits at half scale instead of at the flag's measured crossing. The example sweeps the whole range and writes a frame per nat, because the question a photographer asks of a slider is where to put it, and that needs the travel rather than a point on it.

dtourolleandClaude Opus 5	4f4abd335f	Cut a scene category back to the pixels that agree with it ... A flag in the sky came out weighted as sky, and no feather setting fixed it. The scene model's logits are `[1, 150, 80, 80]`, so one cell is eight input pixels; at the 1600px proxy the letterbox scale is 0.4 and **one cell is 20 proxy pixels**, which `rasterise`'s bilinear then spreads across one more either side. A flag is a handful of cells whose softmax is dominated by the sky around it. The information was never in the grid, so nothing downstream of the grid can recover it. Tiling is the answer for an instance and is not available here: a category has no bounding box to tile over — sky is wherever the sky is. But the photograph is at full proxy resolution even though the weights are not, and it knows exactly where the flag is. So the model says *what*, and the pixels say *which of them*, which is the division of labour arm C already draws between the instance model and the watershed. ## Seeds, and why the erosion radius is not a guess Threshold the weights high, take `signed_distance`, and keep what is more than 1.5 cells inside. One cell *is* the model's resolution and the bilinear spreads it across one more, so the band either side of the boundary is smear rather than evidence. Deriving the radius from `Scene::cell_pixels` rather than picking a pixel count means it stays right if the proxy edge or the export changes. The mirror of that set is a confident *exterior*, free from the same field. ## Dropping small modes is the step that makes it work Four k-means modes per side, not one Gaussian: sky is blue at the zenith, white where the cloud is and pale at the horizon, and one blob over all three rejects two of them. Then modes holding under 3% of a side are discarded, and without that step the whole thing fails on the case it was built for. A small flag deep in the sky has both a high weight and a large distance from the boundary, so it lands in the interior sample and teaches the model its own colour. It cannot be excluded geometrically. It can be excluded by share. Luminance is weighted at a quarter against chrominance for the same reason the watershed's gradient is. Sky's variance is dominated by luminance, so at equal weight the distribution is a long bright streak that a mid-grey flag sits comfortably inside. A flag is separated by chrominance; a cloud is separated by luminance alone. Not zero, or a dark bird against a bright sky survives. ## Two tests, because either alone is wrong Absolute — is this colour plausible under the category, as a chi-square on the Mahalanobis distance. Comparative — is it likelier inside than outside. A pixel must pass both. The absolute test is what catches the flag, whose colour is far from *both* sides and which the comparative test alone would leave at even odds. The comparative test is what stops the absolute one needing a constant tuned per category. ## What this cannot do, written down rather than left to be discovered An intruder large enough to hold its own mode is kept. By share, a flag over a fifth of the sky and a cloud bank over a fifth of the sky are the same object, and colour does not separate them either — a white cloud is as far from blue sky in chrominance as many intruders are. So `min_cluster` is not a threshold with a correct value waiting to be found; it is the trade-off itself, set where a photographic intruder falls. Both ends are pinned by tests — `a_flag_in_the_sky_is_removed` and `an_intruder_larger_than_min_cluster_survives` — so that moving the number reads as moving the trade-off rather than as fixing a bug. The case left open is a large unrecognised object in a clean category, which wants the boundary snapped to watershed basins and is a different mechanism. ## Safe to apply without a control It is subtractive: the output is the input times a factor in `0..=1`. The worst failure available to it is losing part of a real sky, never gaining a region, so a blue car below the horizon that was never in the mask cannot be pulled into it. And a factor in `0..=1` cannot raise a sum, so `scene.rs`'s partition still holds when every category is refined independently — the weight taken off the flag lands in the unlisted remainder, which is where a flag belongs, ADE20K having no class for one. Every path without the evidence to judge returns the weights untouched and says which path it took. A refinement that silently did nothing is indistinguishable from the feature being off, and an empty seed set fitted to a distribution would reject every pixel. The signature is deliberately unchanged: categories are addressed by name, not by index, so a sharper mask cannot create the stale-index hazard the signature exists to guard against. The example writes `<prefix>-<category>-refined.ppm` beside the coarse one, never instead of it — whether this is an improvement is a comparative judgement and one image cannot answer it.

dtourolleandClaude Opus 5	8131706394	Regenerate the matrix over the merged rail work ...

dtourolleandClaude Opus 5	bfdb6d5e4b	Cut the People rail's portraits off the blocking path ... Opening Identity cut a portrait for every person before the screen was allowed to appear. Measured against the reference library: 3.6 seconds, of which 3.2 is 931 full 1024px proxy decodes — the fallback for faces indexed before crops were stored beside them. The rest of the wait was the rail building 14,268 rows, fixed in the commit before this. `refresh` now draws with the portraits already cached and hands the rest to `fill_covers`, which cuts them 8ms at a time — under half a frame — behind a screen that is already up. Blocking work on that path goes from 4,965ms to 16ms on this library. A timer rather than a thread. The work is a catalog query and a decode against a `ThumbStore`, and both handles live on the UI thread; a worker would need its own connection to the same file, which is what the sweep and the regrouping pass do because they run for minutes and would otherwise be unbounded. This is seconds of small, independent pieces, so slicing answers the same question more cheaply. `pending` is in rail order, and the rail is sorted by confirmed faces, so the portraits the user is looking at are cut first. It patches single rows rather than reloading: a reload would rebuild the model on every tick, and a model replaced underneath the `ListView` is what the slicing exists to avoid. Each patch checks the row still holds the person it was started for — a stale index would draw a face beside somebody else's name — and stops the fill when it does not.

dtourolleandClaude Opus 5	d7b851f622	Build the People rail rows you can see, not the ones you cannot ... `Flickable { VerticalLayout { for ... } }` instantiates every row. On the reference library that is 14,268 row subtrees, which measures at 4.2 seconds before a pixel is drawn — and it was paid again on every action, because every action reloads the model. Roughly half the wait between clicking "Identity" and the screen appearing was this. Slint's compiler has a virtualising path for a `for`; it is what makes `std-widgets`' `ListView` cheap. It keys on the parent element's base being *named* `ListView` and exposing the five lengths its layouting code writes back, and a custom base is explicitly allowed. So `widgets.slint` grows one, and `std-widgets` stays out of the file that establishes our style. Measured on the real screen: 200,000 rail rows now render in 62ms. Three things had to be true together, and each was silent on its own. **The row height must be constant.** The rail hid a set-aside person with `height: cond ? 52px : 0px`, a height that reads the model — so the layout cannot place row N without building rows 0..N, and Slint builds them all. The filtering moves to Rust, where the toggle was already reloading anyway. **The list must not be wrapped.** It carries its own stretch and preferred size, having no natural height to offer; a Rectangle in between hands the layout that Rectangle's constraints, which are taken from the list and are therefore nothing. **The panel must let it fill.** `Panel` lays its children out with `alignment: start`, which gives each its preferred height — right for a column of sliders, wrong for anything that scrolls. Hence `Panel.fill`. Get any of them wrong and the rail renders empty, with no error and a model full of people. All three were, in turn, before a headless render of the real screen showed a blank rail. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-30 18:30:16 +02:00
dtourolleandClaude Opus 5	f26f1ab694	Withhold the empty groups that fill the People rail ... `load_people` returned every live person, and on the reference library that was 14,268 rows of which 11,739 held no faces at all — 85 per cent of the rail naming nobody and able to do nothing. They are not a mystery. A regrouping pass creates a person per cluster; the next pass moves those faces elsewhere and leaves the person it emptied behind. `faces::prune_empty_unnamed` exists for exactly this and runs only at the end of a pass, so nothing clears what accumulates between them, and the Identity screen never prunes at all. Each one cost a `for_person` query and a built row on every reload. This withholds precisely the set the prune already treats as disposable — empty, unnamed, not set aside — and no more. Filtered rather than deleted: a screen is being drawn, not a catalog repaired. Nothing is lost, a sync cannot resurrect what was never removed, and the prune stays the one place that decides these can go. An empty group with a *name* still shows. That one is not debris but the symptom of a real failure — a named person whose faces were regrouped out from under them — and hiding it would take away the only way to merge them back.

dtourolleandClaude Opus 5	e8b072c815	Say the app is starting before there is anything to say it with ... Nothing from our own code reached logcat on the tablet: 284 lines from the app's PID during a launch, every one of them from Hwaps, BlockMonitor, InputEventReceiver or nativeloader, and not even the version banner android_main emits three statements in. I could not find the fault in our wiring, and this commit does not claim to fix it. What it does is make the next launch say which side is at fault, and close a hole that is real whatever the answer turns out to be. What reading rules out, so nobody repeats it: install does call log::set_max_level. The Config carries an explicit tag and an explicit max level, and its env_filter is None, so android_logger's enabled() and filter_matches() both pass an Info record. Tee::enabled delegates to the console and gates nothing else. set_boxed_logger cannot have failed — its Err path drops the Tee, taking the LogFile with it, and the file on the device has content. And Tee::log calls console.log() unconditionally *before* the file write, which is itself gated on console.enabled(), so every line that reached the file proves the AndroidLogger was handed the same record. Nothing else in the graph installs a logger; android-activity and Slint's backend do not. The diff that introduced this changed the level, the tag and the Config not at all — init_once and set_boxed_logger leave the same logger installed at the same level. That leaves below __android_log_write, which no amount of reading this file can reach. So: the console logger is now built first, and one line goes through it directly, before the state directory and before the log file. Two things follow. Everything between android_main's first statement and install returning — external_data_path, create_dir_all and an open on a FUSE volume the system may still be mounting — currently has no surface at all to fail on; that window is what logcat is for, and it now has a line in it. And when the log is silent, that line separates the two cases: present with the log::info! lines below it missing is the facade, absent along with them is liblog not delivering this process's records. It goes through Log::log rather than log::info!, which is not a style choice: the facade's maximum level is Off until install sets it, so a log::info! there compiles and emits nothing.

dtourolleandClaude Opus 5	c62edd3317	Give the log a mode that the way off the device can open ... The log file has been on external storage since it existed, and the reason is stated at length in two places: /data/data/<pkg>/files needs run-as against a debuggable build, /sdcard/Android/data/<pkg>/files is a plain adb pull from any build, and a log nobody can retrieve is not a diagnostic. The file was then opened 0600, which cancels that decision out. On the tablet: adb pull -> remote open failed: Permission denied adb shell cat -> Permission denied run-as -> package not debuggable Every route off the device closed at once, on a file whose whole purpose is to leave the device. The mode is now per platform, because "who may read this" has two different answers and the directory above the file is what makes them differ. On the desktop, 0600 as before: $XDG_STATE_HOME/darkroom is in a home directory on a machine that may have other accounts, and nothing about that directory stops another local user reading a world-readable file. On Android, 0644: /sdcard/Android/data is drwxrws--x media_rw:ext_data_rw, so no other app can enter this app's subdirectory and anyone who can traverse it is holding the unlocked tablet, which already gets them the photographs the log merely names. What the read bits buy is adb pull, which runs as shell — able to traverse a --x directory, but then obliged to open the file as other. The mode is also applied twice, and the second one is the fix rather than belt and braces. OpenOptions::mode is a request: the kernel ANDs it with the process umask, and an Android application process inherits 0o077 from the zygote, so asking for 0644 there creates 0600 and reports nothing. It is ignored outright on a file that already exists, which every launch after the first has. fchmod is subject to neither, and is what the second call makes. The comment claiming the mode was "ignored by the FAT-derived filesystem Android presents as external storage" is gone with it. The device says otherwise: the file it produced was 0600 exactly. Two tests. One pins the literal mode per platform — only the desktop arm can run under cargo test, and the comment says so rather than implying the Android number is covered. The other reopens a log left behind with the wrong mode, which is the one assertion on the host that fails if the fchmod is deleted, since OpenOptions::mode cannot touch a file that is already there.

dtourolleandClaude Opus 5	23c3155128	Release 0.10.0 ... Three waves of work since 0.9.0. Culling gained the two instruments FR-CULL-3 asked for and never had: focus peaking, and a histogram that reads the sensor rather than the frame about to be displayed. Bursts group themselves. Masks can cover a whole category rather than one instance. The catalog now notices when it has been damaged and offers a way back -- restore a backup, or rebuild from the photographs, which were never at risk. A crash leaves a record. A log survives the process, on a path a tablet will hand back to adb, which is what makes the Android work debuggable at all. The APK compiles its own Java for the first time, so the app can receive a photograph from another application and hand one back. Memory pressure is answered in a stated order. A lost library root is reported rather than reported as an empty library. There is a benchmark suite now, so §8's promise that a regression fails the build is a mechanism rather than a sentence. Its first run says the catalog opens in 70ms against a 2s budget, and that thumbnail throughput does not obviously reach its target. Coverage 59.8% -> 69.8%, and it means more than it did: five requirements that were tagged on code that did not implement them are no longer, and the tool no longer counts its own test fixtures.
