dtourolleandClaude Opus 5	f00b3ae924	Take the tone from the hole and the texture from beside it ... A clone gets the texture right and the level wrong. Dust on a gradient sky is copied from a patch a little lighter than the hole it fills, and the repair reads as a disc even though every grain in it is correct — which is why FR-DEV-8 asks for heal and not only for clone. Heal adds the membrane: the difference between the two neighbourhoods, sampled at twenty-four points around the rim and interpolated across the disc by inverse square distance. Solving the Poisson problem properly is tens of Jacobi iterations, and an iteration here is a dispatch — sixty dispatches to remove a dust spot is not a frame budget. The closed form costs one loop over the rim, no state, and no second pass. The spec called for mean-value weights; inverse squares are two transcendentals per sample cheaper and agree wherever the boundary difference varies smoothly, which is every repair anyone makes. What decides whether that trade holds is the measurement, so the measurement is the test: on a ramp steep enough to leave a clone wrong by 38 levels out of 255, the heal is wrong by 0. docs/spot-removal.md §6.1 records what shipped and what it would take to go back.

dtourolleandClaude Opus 5	5323608051	Draw the repairs, before anything sharpens what they removed ... A spot set now composes detail passes of its own, one per round, and they go ahead of every operation's kernel. That placement is the decision worth recording: a sharpening pass reads a neighbourhood, so sharpening a dust mark before removing it smears its edge into pixels the repair's disc does not cover, and what survives is a faint over-sharpened ring around an otherwise perfect patch. It also disagrees with ARCH §5.2, which draws spot removal after clarity — docs/spot-removal.md §5.1 is where that is argued out. Every length reaching the shader is in render pixels, converted here where the framing is in scope. Both the centre and the source go through `Framing::output_at` — the same map the fused pass applies to every pixel — so a rotated photograph rotates the offset with no trigonometry, and the radius is found by mapping a point one radius above the centre and measuring, rather than by multiplying by a ratio this function has no business knowing about. The tests turn and crop the frame and expect the mark to stay gone, which is the property that arrangement buys. compose_full now takes the spot set, because a photograph with a repair and no sharpening still has a detail stage: a fused pass that encoded its own output there would quantise twice and bind to a texture of the wrong format. compose_detail_for takes the source size for the same kind of reason — a RenderScale describes the region on screen, and a spot is stored against the photograph.

dtourolleandClaude Opus 5	00e78dc2ac	Cluster faces into people, and calibrate what a similarity means ... FR-CULL-9 forbids thresholding a bare cosine anywhere in the subsystem, so calibrate fits P(same person) per library and reports whether the fit is trustworthy. Two details carry most of the weight. The fit runs against a 200-bin histogram rather than a pair list: a 25,000-face library has ~3e8 pairs and no gradient descent is running over that. And a fresh library has no valid calibration, because the positives have to come from user confirmations or burst siblings -- bootstrapping them from high cosine would fit the calibration to the belief it was supposed to test. Clustering defends against the over-merging FR-CULL-10 warns about with constraints rather than a better threshold: two faces in one photograph never merge, and two groups confirmed as different people never merge. Average link rather than single link, so one strong edge cannot weld two families together. Calibration is defined once, in dr-face, and dr-catalog re-exports it. Two implementations of one probability model is exactly how a number comes to mean the wrong thing. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-26 20:10:33 +02:00
dtourolleandClaude Opus 5	aac3136407	Store faces and the people they belong to ... Schema v8: people, faces, face_person, face_person_rejected, and the per-library calibration. Follows catalog.md 10.1 with two additions the spec work turned up. crop_px, because at the 1024px proxy tier a group shot reaches the embedder at ~50 source pixels upsampled to 112 and a portrait at 340. FR-CULL-9 names face size as an axis along which an uncalibrated similarity misbehaves, so it is a stored feature rather than a UI hint. face_person_rejected, because rejection is not the absence of an assignment. Without it the next clustering pass re-suggests exactly the face the user just pushed away, and the tool feels broken. record_detections replaces rather than appends, since DetectFaces is coalesced per image -- and carries confirmations across the replacement by box overlap, so re-indexing with a better model cannot discard the user's own labelling.

dtourolleandClaude Opus 5	6997c0f7ac	Let a detail pass carry a list, not only a kernel ... Every neighbourhood pass so far has been a convolution, whose whole description fits in the uniform block because its structure fixes how many numbers it needs. Spot removal is not that shape: sixty-four repairs and one repair are the same shader with a different buffer behind it. So a pass may declare `storage`, which arrives at binding 3 as `array<vec4<f32>>` with `arrayLength` in scope. The alternative — packing the list into uniforms — needs a fixed maximum paid for on every frame, a composer that can emit vec4 fields because a uniform array's stride is 16 whatever it holds, and it gives the next operation that wants a table nothing to build on. The property worth having is what stays out of the generated source: the count is in the buffer, so placing the tenth spot uploads 512 bytes and reuses the compiled pipeline, exactly as moving a slider does for the fused pass. `changing_the_list_does_not_recompile` is that, asserted. One bind group entry rather than two more layouts, and one placeholder buffer allocated in `new` rather than sixteen bytes per pass per frame — a zero-length storage buffer cannot be bound, and per-frame allocation is what this module's documentation exists to refuse.

dtourolleandClaude Opus 5	19981c1033	Detect, align and embed faces with SCRFD and MobileFaceNet ... Ports the pipeline from the C++ reference in ../scene-actor-extraction (MIT, same author). End to end on real portraits it separates identities the way the reference's fitted calibration says it should: 0.596 between distinct photographs of one person, 0.05 between different people, either side of MBF's 0.267 boundary. Three things are structural rather than incidental: Aligned112 can only be built by align::warp, so Embedder::embed cannot be handed an unaligned bounding-box crop. That mistake yields 512 plausible unit-norm numbers and no error, so the type system refuses it instead. Embedding carries its ModelId and cosine() returns None across models, because a cross-model similarity is the one mistake that produces plausible garbage rather than a failure. The model-free half -- alignment, embedding arithmetic, f16 storage -- sits outside the inference feature and is covered by 11 tests that need no weights on the machine.

dtourolleandClaude Opus 5	44444f7768	Write the repairs down, one line each, and merge them by id ... A spot is eight numbers, so it goes in the version block as a line rather than in a block of its own the way a mask does — sixty-four blocks would bury the rest of the file. A line per spot rather than one line for the set, because the line is what a diff shows and what a merge resolves. The parse arm sits ahead of the op.param arm deliberately: without it, `spot.abc123 = 0.4 0.6 …` reads as an operation called `spot` whose value will not parse, and the repair is dropped with a warning about a corrupt number. The prefix is safe precisely because a spot is not an operation, so no ops/ declaration can claim the name. Merging is merge_masks by id, one level down, and it is where the derived ids earn their keep: two devices that removed different marks hold different ids and both survive, while two that removed the same piece of dust hold the same id and the merge sees the one repair it is. A spot both sides dragged resolves whole to the higher revision — eight numbers describe one disc, and half of each is a repair neither photographer made.

dtourolleandClaude Opus 5	72410f39c6	Answer M1: tract loads both face graphs once their dims are pinned ... Neither InsightFace export parses as shipped -- SCRFD fails at its input node, ArcFace at the first Conv -- which is the same wall dr-segment hit on YOLO's dynamic export. Both load cleanly with the input dims frozen, so the pure-Rust runtime holds for the face pipeline too. tools/fix-face-model-shapes.sh does the freezing, and exists so the artefact is reproducible rather than a binary someone once produced. It takes two forms because the two graphs need different ones: ArcFace's batch is a named dim_param, SCRFD's H and W are dynamic but unnamed. Also notes YuNet loading with no intervention, which matters for the licence question in faces.md 2.3. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-26 19:51:02 +02:00
dtourolleandClaude Opus 5	97479a0512	Hold the repairs a photographer makes, and say which may share a pass ... A spot is a disc, a source offset and four numbers, and it lives beside `ops` for the reason `masks` and `film` do: the operation trait is ParamId -> f32, and a list of repairs is neither scalar nor fixed. Two decisions here are not obvious. The id is derived from the position rather than counted, because two devices editing offline would each mint `spot3` for different marks and the sidecar merge would then treat two repairs as one — from the position, two devices that removed the same piece of dust agree, and two that removed different ones do not. And every length is in the frame's isotropic units, not a mixture of those and shorter-edge fractions: one unit for the radius, the feather and the offset agrees on a landscape frame and on a portrait one, where a mixture only agrees on the first. `rounds` is the arithmetic that keeps a source from reading a destination. Every spot in one pass reads the photograph as it stood before that pass, so a spot sourcing from an earlier spot's destination would copy the mark that spot was removing. Grouping is not a pass per spot — that is sixty-four dispatches for a case that almost never arises — it is a new round only when the sources actually collide.

dtourolleandClaude Opus 5	ec740115b6	Spec the face pipeline on SCRFD and MobileFaceNet ... FR-CULL-8..12 specify the subsystem in terms of "a 512-dimension embedding from a stated model" and stop there, because D13 was open. This names the models, and grounds them in the measurements and the working C++ pipeline in ../scene-actor-extraction rather than in a literature reading. The licensing half of D13 stays open, but with a route through it: the InsightFace weights are non-commercial and cannot be committed, so the app ships the code and the user fetches the model. faces.model_id already makes that a survivable choice.

dtourolleandClaude Opus 5	8d8d6491ad	Say how spot removal is going to work before writing it ... FR-DEV-8 is the last develop requirement with nothing behind it. The pipeline it lands on already has most of the parts — the neighbourhood stage, the mask crate's normalised coordinates, the gradient handles' canvas drags, the merge-by-id rule — so the spec is mostly about the four things that are genuinely new, and about the two places where the obvious implementation is the wrong one: a Poisson solve is sixty dispatches per spot, and a per-frame readback to find out what colour a sky is would undo ARCH §6.1.

dtourolleandClaude Opus 5	f82c69bc6b	Say which version this is: 0.7.0 ... Film simulation is a feature, not a fix: five Ilford stocks, a grain model that counts silver rather than adding noise, and the pipeline and UI to drive them. 0.6.0 was tagged thirty-one commits ago and does not describe any of that. The Android versionCode follows from this without being restated -- package.sh packs MAJOR*10000 + MINOR*100 + PATCH, so 0.7.0 is 700, above the 600 already installed on devices and therefore an upgrade rather than a refusal.

dtourolleandClaude Opus 5	f14176de29	Give the projector lamp a name instead of a warning ... Every bake of a Vision3 stock logged: unknown illuminant "K75P", falling back to D55 K75P is a cinema xenon short-arc lamp, and Kodak 2383 and 2393 -- the projection print films those stocks print onto -- name it as the light their result is looked at under. It was never implemented, so it fell through to the unknown branch. The fallback was the right family: a xenon arc sits near 6000 K, close to daylight and nothing like the tungsten enlarger above it. So the pixels do not move. What changes is that D55 is now a documented choice rather than the consolation prize for an unrecognised string, with the approximation stated -- an arc has line structure a Planckian curve cannot express, and the residue of that is small here because the viewing step adapts the white point out either way. The test is the point of the commit. A profile naming a light nobody implemented should fail the suite, not whisper into a log that only gets read when somebody happens to be looking for something else -- which is how this was found.

dtourolleandClaude Opus 5	4b50648870	Rebuild the film tables when the film's own sliders move ... Push and print exposure did nothing at all. The parameter was set and the tables were never rebuilt, so the shader went on running the stock as it had been baked. The check asked the wrong list: self.rows() // one entry per *parameter*, tab-filtered .get(op_index as usize) // indexed by an *operation* index .map(|_| ()) .and( ...the real check... ) `op_index` counts over the scoped capabilities -- it is what `lookup` resolves a slider through -- so capabilities is the only list to ask. Indexing `rows()` served no purpose, and past its end the `and` short-circuited to None and the rebake silently never happened. Both halves of that are worth saying. It was wrong, and it was convoluted, and the convolution is what hid the wrongness: a one-line check would have been obviously right or obviously broken. This is a class of bug the suite cannot reach. The tables are rebuilt in the interface layer, in response to a control, and every test either side of it passed throughout -- dr-film computed the pushed curves correctly and the shader rendered whatever it was handed. Only moving the slider showed it. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>	2026-08-26 17:35:25 +02:00
dtourolleandClaude Opus 5	ff1a3e0e80	Print the black-and-white negatives instead of showing the scan ... Choosing Ilford HP5 Plus showed an inverted grey frame. So did Double-X. They are negatives, and upstream leaves `target_print` null on every monochrome stock, so nothing was ever printed and the scan was all there was. A colour negative at least announces itself -- the orange mask says plainly that you are looking at a negative. A monochrome one just looks broken. They print on Kodak 2302 now, which is a monochrome print film and is what such a negative is actually printed onto; Double-X onto 2302 is the standard cine chain. For the Ilford stocks it stands in for an Ilford paper, which nobody has measured, and is at least the right kind of material. The scan is still reachable through the Scanned/Printed toggle. It is a thing to choose now rather than the only thing on offer. `every_shipped_stock_bakes` did not catch this, and could not: it derives "should this be inverted?" from the stock's kind *and whether it names a paper*, so it looked at an inverted HP5, concluded that was right for an unprinted negative, and passed. The assertion was self-consistent and the situation was still wrong. The new test asserts the thing that actually matters -- a camera negative must name a paper, that paper must be a printing stock, and it must be the same kind of material, so a monochrome negative cannot end up on colour paper.

dtourolleandClaude Opus 5	ce6458547a	Develop longer, from the measurements rather than from a contrast slider ... Pushing was not a thing to simulate. It was measured data being thrown away: Double-X and 2302 each ship five characteristic curves, one per development time, and this shipped the 6.5-minute column and discarded four. All five now ship and interpolate. The axis is real. Double-X runs 4 to 12 minutes, and across it the average gradient goes 0.472 to 1.034 while Dmax goes 1.19 to 2.56. The control is in stops, because that is what a photographer means, and one stop is a factor of about 1.41 in time. That mapping is checked rather than assumed: against Double-X's own axis it lands within 2% of the 9-minute column for +1, and near 12 minutes for +2, which are the times the datasheet gives for exactly that. There is a test. **Pushing must not recover shadow detail, and this does not.** Across the whole measured range the speed point moves about a third of a stop while the gradient doubles; three stops under mid-grey, density goes from 0.008 to 0.035, which is still nothing. Developing longer multiplies what was already recorded and cannot record what never hit the film. A push built as added exposure or global contrast brightens those shadows instead and looks convincing until someone who shoots film sees it, so that property has a test of its own. Interpolated in *log* time, because development is multiplicative: 4 to 5 minutes is the same amount of push as 9 to 12, and interpolating linearly would bunch the control at one end. Clamped at both ends, because past the published range there is no data and extrapolating a contrast curve invents an emulsion nobody tested. A stock measured at one process ignores the control entirely rather than inventing a curve for it -- Portra 800's pushes are separate *measured* profiles, which is the honest way to offer those. Costs nothing per pixel and changes no shader. The curves are a per-stock table, so the interpolation happens on the CPU at bake time, where choosing a stock and moving its sliders already rebakes. The Vulkan shader is untouched. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>	2026-08-26 17:35:25 +02:00
dtourolleandClaude Opus 5	8f863ec56f	Put file(1) in the Android image too ... The android job now fetches the model and cross-compiles the whole app -- 28 minutes of it -- and then dies on file: not found (exit 127) `Verify minimum API level` reads the linked API out of the .so's ELF notes with file(1), and the image has never had it. Like git-lfs, the absence could not show until something got that far: every previous run panicked in dr-segment's build script long before this line, so the step that was going to fail never ran. Audited the rest of what the remaining steps invoke against the image rather than find the next one the same expensive way -- zip, keytool, base64, mktemp, shred, find, sed, awk, and aapt2/zipalign/apksigner/d8 from build-tools are all present. file was the only gap left.

dtourolleandClaude Opus 5	b9ee29f3c7	Regenerate the traceability matrix for the Ilford stocks ... Same drift as before and for the same reason: the matrix links to line numbers, and the grain work moved lines in files that carry tags. The stocks bring six new files and ten new tags -- 227 scanned against 221, 614 found against 604 -- all on requirements that were already covered, so coverage is 51.4% (91/177) either side. Twelve rows move and nothing else changes. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>	2026-08-26 10:14:29 +02:00
dtourolleandClaude Opus 5	40e6334bb1	Sign the APK with a real key when one is configured ... The APK has been debug-signed with a key generated on the spot, which is right for putting a build on a test device and useless for anything else: a different signature every run, so nothing can ever update in place. Four secrets now select a real signature -- ANDROID_KEYSTORE_BASE64 and its password, alias and key password. The names are JellyTau's, because that repo already signs its Android build this way against this same runner and one convention across both is one thing to remember. Absence of the secrets is not an error. A fork or a branch build has no access to them and should still produce an installable APK, so the debug path stays exactly as it was. The reverse is an error: if a keystore is supplied and cannot be read, the build fails rather than quietly falling back to a debug key, because a release that is silently debug-signed is worse than no release. Passwords reach apksigner and keytool as `env:`, never `pass:`. `pass:` puts the password in the process table for anything on the box to read. The keystore is written to a 0700 mktemp directory and never into the workspace, which is both what actions/cache saves and what the upload step globs. Also: upload-artifact drops from v4 to v3. v4 was a guess about what this Gitea supports. v3 is what JellyTau uploads its APK with on this runner today, which makes it the version known to work rather than the one that ought to.

dtourolleandClaude Opus 5	e9b3598841	Add five Ilford stocks, and say plainly that they are constructed ... They were asked for and they are here, but not on the same footing as the Kodak profiles, and the files say so in their first line. What I had claimed, and had to withdraw: that Delta 100 is "quoted around 9" and HP5 "around 12". Ilford publish no such figures. The word granularity does not occur anywhere in their technical information -- grain is described as "fine" and "finest" and nothing more. That claim was in this crate's documentation as though it came from a datasheet; it is corrected there too. Two further traps found while looking: - Kodak colour negatives publish Print Grain Index, not RMS granularity. PGI is a perceptual scale from viewer surveys -- 25 is roughly the threshold of visibility, four units a just-noticeable difference -- and Kodak state it cannot be compared to RMS. So a Portra number cannot be dropped into the granularity field, and none has been. - RMS proper is published mostly for black-and-white, reversal and motion picture stocks. Every shipped stock therefore still carries the same default, which means grain does not yet tell one film from another. That is per-stock data, not code, and is now written down where somebody will find it. So the Ilford profiles are built rather than extracted, and each part rests on something different: speed published and exact -- ISO 400/27 for HP5 is a fact contrast ISO 6:1993's normal development, average gradient 0.62 spectral borrowed from Kodak Double-X, a *measured* panchromatic negative, shifted by the speed difference. Conventional panchromatic sensitisation is much alike across black-and-white films, and this is far better founded than reading pixels off a printed curve silver neutral, which is not an approximation: developed silver absorbs flat, and Double-X's measurement is flat granularity estimated, ordered by each film's known relative grain They render as a film of that speed and contrast. They are not a measurement of that emulsion, and the two stocks that share a speed differ only in the estimated part. `every_shipped_stock_bakes` is tightened to match, because a constructed profile fails in a way a measured one does not: the curve parses, bakes, and sits entirely off one end of its own exposure range, rendering every frame black or blown while passing a finiteness check. It now asserts mid-grey lands somewhere photographic and that the tone response runs the way the stock's kind says it should.

dtourolleandClaude Opus 5	4b2ee0ac50	Count the silver instead of adding noise ... An emulsion is a suspension of crystals. Light sensitises some; development turns a sensitised one opaque, all or nothing. So a patch of film's density is a *count* of developed grains, and a count of independent yes/no events has a variance whether or not anyone wanted texture: mean = D variance = D * (Dmax - u * D) / N That expression is the whole feature. It peaks in the middle of the density range and vanishes at both ends -- clear film has nothing developed to vary, black film has nothing left to develop -- so grain lives in the midtones as a consequence rather than as a "midtone bias" slider. I was wrong earlier that this needs the detail stage. Nothing in it reads a neighbouring pixel; the only reason to move it was that grain must be fixed in film space rather than screen space, and that solves itself: N is grains *per pixel*, so it scales with the film a pixel covers. Zoom out, each pixel averages more grains, less variance -- correct, with nothing super-sampled and nothing filtered. It stays in the fused pass. Grain goes on the density and *before* the dye, which is the physical order and not cosmetic. Perturbing the finished colour -- what an effect does -- tints highlights wrong, because that noise never passes through the dye. Crystal habit lives in `rms_granularity`, the number every datasheet publishes, now a profile field. It measures exactly what differs between a cubic emulsion and a tabular one: at equal speed, tabular crystals present more area per unit silver, so the film reads finer. Delta 100 is quoted near 9 where HP5 is near 12, and that gap *is* the habit. Adding a stock whose grain is its whole reputation is therefore editing one line, not writing a model. Three things this cost, all of them worth writing down: - The default granularity is a colour negative's, blue coarsest. Applied to Tri-X it put *colour* speckle on a black and white photograph. Monochrome stocks collapse it at parse, where every other per-layer table is already replicated from the one measured channel. - Helpers cannot read uniforms. The composer prefixes a uniform with its operation's id and rewrites references inside a fragment body only; helpers are shared and deduplicated, so a bare `gn0` names nothing. `film_lut` already took its size as an argument for this reason, and now says so. - The end-to-end test compares the shader against the CPU model, and grain is stochastic, so that comparison now runs with grain off. Which means a grain that never left the CPU would look exactly like a passing suite -- hence a second test that grain off is bit-identical, one grain per pixel moves it, and ten thousand move it less. Not here, deliberately: no grain slider. The parameters are physical and `rms_granularity` is the honest place to scale one from, but its range wants choosing rather than guessing. Nor a film format -- 35 mm is assumed, and medium format at the same stock is far less grainy per unit of picture. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>	2026-08-26 10:08:51 +02:00
dtourolleandClaude Opus 5	1d38015a7b	Put git-lfs in the Android image, which never had it ... The Android job has never fetched the model. Not because of the header collision the desktop job hit -- that one is fixed and the desktop job now pulls all 11 MB -- but because the image has no git-lfs at all: git: 'lfs' is not a git command. See 'git --help'. The fetch step dies on its first line, `git lfs install --local`, before any of the auth handling runs. The build then panics in dr-segment's build script with a message telling you to run `git lfs install && git lfs pull` -- advice that could not have worked, because the client it names was never in the image to run. Both jobs failing their fetch step at the same time made this look like one bug with one cause. It was two, in two different images, and the desktop one was noisier: it had a client, so it got as far as an HTTP error worth reading. The android one had nothing to say beyond the name of a missing command. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>	2026-08-26 06:52:50 +02:00
dtourolleandClaude Opus 5	56bdd457dd	Stop the test build filling the runner's disk ... The desktop job died mid-link with LLVM reporting "IO failure on output stream", which reads like a compiler crash and is not one: underneath it is `No space left on device`. The runner ran out of disk while linking. Worth knowing what it was spending it on. `target/debug` was 24 GB against `target/release`'s 2.6 GB -- the test build is roughly ninety percent of the footprint -- and of that, 15 GB was debug info in `debug/deps` and 3.6 GB was incremental state. Neither buys anything here. Nothing attaches a debugger to a CI run, and incremental compilation exists to make the second build in a working tree fast, which is not a thing a fresh checkout ever has. With both off the same tree is 3.3 GB, `debug/deps` 2.8 GB, and the test binaries build unchanged. Backtraces keep function names and lose file and line numbers; if a failure ever needs those, DEBUG=1 gives line tables back for a fraction of the 15 GB. A `df -h` either side of the expensive steps, so the next time this happens it says so in one line rather than as an error from LLVM. This is a mitigation and it should not be mistaken for the fix. It bounds what this job asks for; it cannot help if the runner is full of anything else, and 24 GB of build output is not obviously the largest thing on a host that also keeps every cached target directory this workflow has ever saved. If it fails here again, the disk needs looking at on draco-x86. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>	2026-08-26 01:13:32 +02:00
dtourolleandClaude Opus 5	834b219c3f	Publish the Android APK as a build artefact ... The android job proved the app links for aarch64 and then threw the result away. There was no APK anywhere in CI and no upload step in the repo at all, so a green run left nothing anybody could install -- the artefact list was empty by construction, not by failure. It now assembles the APK with the script package.sh uses and uploads it. The .so comes from the build the API-level check already ran; -o only adds a copy of it where the packaging step looks, so this costs one copy rather than a second twenty-minute cross-compile. The signing key is the part worth being careful about. KEYSTORE points at a mktemp directory rather than its default under target-android, because that directory is precisely what actions/cache saves and restores -- the default would have written a private key into the build cache and kept it there. Nothing but the .apk is uploaded. A fresh debug key each run is the right trade for an artefact meant to reach a test device: the only thing a stable key buys is installing over a previous build without uninstalling first, and a key that survives in cache storage to buy it is a bad exchange. if-no-files-found: error because the failure being guarded against is a green run with an empty artefact list, which reads as success right up until somebody goes looking for the file. Debug-signed, arm64-v8a only -- the ABI the job already builds. Neither is a release story; this is a build you can install.

dtourolleandClaude Opus 5	5741ec5e00	Lift the APK assembly out of package.sh so CI can run it too ... package.sh does two things: it decides how the host reaches the image, and it assembles an APK once inside it. Only the first half is host-specific. CI already runs in that image, so the second half was about to be copied into a workflow step -- two copies of aapt2/zipalign/apksigner ordering, drifting apart at whatever rate the toolchain moves. So it moves to docker/android/assemble-apk.sh, which assumes it is inside the image and takes its paths from the environment, because the callers disagree about them: the container mounts the repo at /work, the runner checks it out wherever it likes. Every default reproduces what package.sh did, so the host path is unchanged. Two things stop being hard-coded on the way. The build-tools version and the compile SDK are resolved from what is installed rather than written out as 36.0.0 and android-36 -- the versions are Dockerfile ARGs, and a second copy is a second thing to miss when they move. --min-sdk-version now comes from that same ARG instead of a literal 28, which is the number the API-level check in CI already reads. The intermediates are removed at the end. They were harmless in a cache directory nobody looks at; beside a published artefact they are four more files for a glob to pick up by mistake.

dtourolleandClaude Opus 5	8b07a90e71	Regenerate the traceability matrix the clippy pass moved ... `traceability-check` fails on master: the committed matrix does not match what the generator produces, so the gate that exists to keep the two in step is the thing reporting they are not. Nothing was traced or untraced. Coverage is 51.4% (91/177) before and after, the same 604 tags against the same 177 requirements; every one of the 32 changed rows is a line number that moved when the clippy warnings were cleared -- `adjust.rs:2150` is now 2164, 632 is 651, 751 is 770. The matrix links to lines, so touching a file above a tag rewrites its row without changing what it says. Regenerated with `cargo run -p traceability -- report`, which is what the failing step tells you to run. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>	2026-08-25 23:21:13 +02:00
dtourolleandClaude Opus 5	606f85df34	Send the LFS object endpoint one Authorization header, not two ... The model fetch has been failing on every run with LFS: Client error: .../info/lfs/objects/0672d7a7... which reads like a rejected credential and is not one. The object is on the server and downloads fine; what fails is the shape of the request. `git lfs pull` makes two calls. The first, to `/info/lfs/objects/batch`, succeeds -- and Gitea answers it with a short-lived `Bearer` JWT scoped to that one object, for git-lfs to use on the second. git-lfs sends that JWT *and* the `Authorization` header this step had installed in git config, and two `Authorization` headers is a 400 from Gitea. Hence a client error on the object one step after the batch call it just made successfully, which is what made this look like an auth problem rather than a duplication. Confirmed directly against the server: the JWT alone on that URL is a 200, the JWT plus any second `Authorization` is a 400, and a lone token header that is merely wrong is a 401 -- so the scheme was never the issue. `lfs: true` on the checkout fails the same way and for the same reason, because actions/checkout persists a header of its own; the comment here blaming a credential the endpoint would not accept was wrong on both counts. So the headers are stripped -- checkout's included, since nothing later in either job talks to the remote -- and the token is handed to git-lfs as an ordinary credential instead. It authenticates the batch call and leaves the per-object JWT alone. This is what fails the Android job today: the build script sees a 133-byte pointer and panics by design, which is the message it is supposed to give and the one nobody could act on.

dtourolleandClaude Opus 5	56978fdf35	Clear the clippy warnings that were failing CI before this branch ... Nothing here is film simulation. These are lints that fail master today, under the -D warnings CI runs with, mostly from a toolchain that learned new ones rather than from anybody's code -- `is_multiple_of` and the derivable `Default` did not exist as lints when this was written. They are fixed rather than allowed, and by hand rather than by trusting `cargo clippy --fix` wholesale: its automatic pass split a derive in two and left a stray blank line, which is the sort of thing that is correct and still wrong to commit. The four that needed a decision rather than a rewrite: - The distance transform's inner loop writes through its iterator now. `q` stays, because it is the position the parabola is evaluated at as well as the index it is written to -- the lint is about the write. - `to_source` and `to_proto` take `self` by value. Their receiver is `Copy`, so this is the same machine code and the honest signature. - The export path's return type is five levels deep and now has a name, plus a line saying why the `Option` wraps the `Result`: `None` is cancellation, which is not a failure and has no error to report. - A test fills a range instead of looping over one.

dtourolleandClaude Opus 5	3b5952769b	Emit floats an f32 can hold, and drop the format! that formats nothing ... CI runs cargo fmt --check and clippy -D warnings, and this branch had never been through either. Both would have failed it. The bulk was the generated colour tables: eight significant figures where an f32 carries about 7.2, so the eighth is noise that rounds away at compile time and clippy's excessive_precision says so 109 times over. Fixed in the generator rather than only in the file, so it stays fixed -- and the file is trimmed in place rather than re-derived, because regenerating it needs a colour-science stack that has nothing to do with the defect. The format! in the composer is mine too, from extracting the rendering tail: the braces in it were escaped because the text used to live inside a larger template, and once extracted the escapes are noise and the call formats nothing. Also here, and clearly not mine: an unused import and a shadowed binding in dr-gpu, and an unused import in a test. They are pre-existing -- clippy has been failing on master before this branch existed, on lints like is_multiple_of that arrived with a toolchain rather than with anyone's code. Fixed because CI cannot go green around them, and called out because a merge commit is a bad place to quietly edit someone else's crate.

dtourolle	6925aa2a86	Merge master into film-simulation ... Master gained the library's index paging while this branch was building the film simulation, and the two met in library_ui.rs.

dtourolleandClaude Opus 5	6d18517d28	Ship every stock that exists, black and white included ... Three profiles was what the first cut needed to prove the model. This is the rest of the open data: 23 camera stocks and 9 papers, which is all of spektrafilm. Black and white was the gap, and it turned out not to be a gap in the data -- it was a gap in where I looked. Upstream's `main` has 28 colour profiles and nothing monochrome; `dev` has three more, and they are Tri-X, Double-X and the 2302 print film they go onto. So the answer to "do we have B&W" was yes all along, and it needed the dev branch rather than a fortnight digitising Ilford's datasheet graphs by eye. Those three are pinned to `dev` per stock; the colour stocks stay on the released branch. A monochrome profile is single-channel -- one emulsion, not three -- and spreading that one layer across all three is exact rather than an approximation: three layers with identical sensitivity and identical curves respond identically, which is what one layer does. The dye is the trap. The renderer *sums* the three layers' contributions, so replicating it unchanged renders every frame three times too dense -- neutrally, and therefore plausibly. A third each reconstructs the single emulsion, and two tests hold both halves: that the densities stay equal, and that they sum to one emulsion and not three. Double-X and 2302 ship five curves apiece, measured at five development times -- 4 to 12 minutes for Double-X. That is push and pull processing as measured data. The standard 6.5 minutes is what ships; the rest is in the upstream file waiting for a control to ask for it. Two stocks are `support: film` and are nevertheless what a negative is printed *onto*: the cine projection films 2383 and 2393, which the Vision3 stocks print to. Filtering the picker on support alone offered a projection stock as something to load in a camera, so it filters on stage, with a test saying so. The picker had to change shape twice over. Chips were right for three stocks and off the edge of a 280px column at twenty-four, and the column that replaced them was a thousand pixels standing between the photographer and every slider below. It is a disclosure now: one row carrying the answer, opened to change it, closed again on choosing. That is the opposite of the argument this panel used to take the lids off its sliders, and deliberately so -- an instrument you compare wants to be visible, and a list you consult once wants to be out of the way.

dtourolleandClaude Opus 5	3330f350a4	Move the timeline marker from the window the grid already read ... The last of the per-scroll queries, and the strangest of them: this one got slower the further down the library you had scrolled. The marker has to follow every scroll event or it advances in jerks while the photographs beside it move smoothly — that part is right and stays. What was wrong is that each event asked the catalog `LIMIT 1 OFFSET n`, and that is not a seek: SQLite reaches row `n` by producing and discarding the `n` rows before it. 0.02 ms near the top of the library, 0.7 ms at twenty thousand, per row crossed, on the thread drawing the frame. A flick therefore got choppier the longer it went on. The window the grid has already read holds the answer, and since the loaded window now covers the whole view, the row is nearly always in it. So this is a vector index at the position the ordinal has in the window, and the query survives only as the fallback for a row outside it — briefly, after a scrub or a keyboard jump, before the load lands. The fallback is also the less correct of the two, which is worth recording rather than quietly keeping: it counts in a dated-only ordering while the argument is a grid row, so the two disagree wherever undated frames sit in between. It is kept because a marker about to be corrected is not worth a second index, and because being wrong there is what it always did. The window path has no such disagreement — it reads the very cell the row belongs to. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-25 20:01:51 +02:00
dtourolleandClaude Opus 5	0f231afe85	Stop re-answering questions about the library every time the window moves ... The timeline's bars, the filter chips' counts, the "on this device" count and whether the scoped collection is pinned all describe the *library*. None of them can change because the view scrolled. `load_window` recomputed all four every time the window moved, which is several times per screenful. Together that is a `MIN`/`MAX`, a `GROUP BY`, two counts, and under a collection three more queries — about 8 ms of SQLite on the thread that is trying to draw the frame, for four answers that were already on screen and already right. They are now keyed on what they actually depend on: the scope, the filter, whether this is the trash, and the total. The total earns its place as the change detector as much as for the scrollbar — a scan landing, a delete or a restore all move it, and it was already read on every load. What a total cannot see is a rating edited under an unchanged count. That is covered, and deliberately not by widening the key: `apply_judgement` already refreshes the chips itself, because it has to report what actually landed rather than what was asked for. Same for the axis — a zoom, a pan, a scrub and dates arriving from the thumbnail worker each call `refresh_timeline` directly. Skipping the recompute here cannot leave anything stale on screen.

dtourolleandClaude Opus 5	6d6ef8d34b	Page the grid along an index instead of sorting the library each time ... Scrolling jittered, and this was the largest single reason. Every window the grid loads is `ORDER BY ... LIMIT n OFFSET k`, and neither half of that was being answered the cheap way. **The sort.** `GRID_ORDER` leads with `captured_at IS NULL`, so undated frames fall to the end. No ordinary index answers that — the leading term is an expression, not a column — so SQLite sorted the whole library into a temp b-tree on every window read, then threw away the first `k` rows of it. Schema V7 indexes the expression exactly as the query writes it, partial on the same `shadowed_by IS NULL AND trashed_at IS NULL` the grid filters by, so the read becomes a walk along the index. **The join.** `LEFT JOIN remote` was paged *after* it was joined, so reading 280 cells at offset 20,000 first seeked into `remote` for all 24,000 rows and then discarded 23,720 of them. The file ids are now fetched for the 280 rows that survived — the shape the badge and rating reads already use, one query for the window rather than one per cell. Measured together on 24,000 images at offset 20,000: **15.2 ms → 0.36 ms**, inside a scroll handler that has 16.7 ms to draw a frame. The test asserts on the query plan rather than on a duration, because there is no other symptom. A `GRID_ORDER` edited out of step with the index, or a column added back that drags `remote` in again, both still return exactly the right cells — just after sorting the library — and the jitter would come back with nothing to point at.

dtourolleandClaude Opus 5	baa8957e80	Let a photographer choose the film, and remember which one ... The stock model rendered correctly and nothing could ask for it. This is the picker, and the sidecar key that makes the choice outlive the session. How the choice persists was the open question, and the answer was already written down twice in sidecar.rs: `rating` is a top-level key "because a rating is not an edit", and `masks` are one "because a layer is not a scalar". A stock is that kind of thing -- a choice of material, not a number a slider moves -- so it is a top-level key too. It stores the **id**, not an index. Stocks are files that users add, so an index would mean installing a profile silently changed which film every existing photograph had been developed on. A name this build has no profile for still round-trips untouched, because the alternative is that syncing to an older phone quietly un-develops the picture. Only the names travel. Turning one back into tables needs the profile database, which dr-pipeline deliberately does not link, so `Version::apply` clears the film and the session re-bakes -- after the parameters, because the bake reads the film's own exposure sliders and the print balance is solved against them. That is also why moving those sliders rebuilds the lookup where no other control in the panel does: an enlarger's filtration depends on how the negative was exposed. The panel keeps its rule. It still names no operation and still generates every control from a declared parameter kind; the stock gets a bespoke control beside those, exactly as the mask stack does, and for the same reason. The film's exposure and print exposure arrive as ordinary generated sliders. Two defaults worth stating. Picking a colour negative prints it, because an unprinted one is an orange strip and offering that as the first thing somebody sees after choosing Portra reads as a bug rather than as a choice -- the toggle is there for anyone who wants the scan. And a paste carries no film: a preset is a parameter map, and a stock is not a parameter, so pasting one would paste a choice the clipboard never took.

dtourolleandClaude Opus 5	4a2fcb6d22	Render a film stock on the GPU, and let it take over the rendering ... The stock model landed in dr-film with no way to see it. This is the pipeline node, the two texture bindings it reads, and the end-to-end test that proves the shader agrees with the model. The design point is that a film simulation is not an adjustment. Every other node changes a picture; this one makes it. A stock's characteristic curve does the camera profile's base curve's job -- from measurements rather than from a curve somebody drew -- so running both renders the scene twice: the camera's rendering, and then a film's rendering of that. It looks like neither, and it reads as a colour-management bug with no colour-management bug to find. So `Operation::renders` is new. A node declaring it takes camera RGB and hands back linear sRGB, and the composer emits neither the base curve nor the conversion out of camera space. Both halves move together, and the composer keeps them as one string precisely so that getting half of it right is impossible. The tables are not parameters, for the reason vignetting's coefficients are not: they are measurements. dr-pipeline declares the layout as a plain struct and keeps its no-dependency property; the two crates share no types on purpose. `EditGraph::set_film_tables` offers them to every node rather than to the one that wants them, because knowing which concrete type is which is what the graph is organised not to know. Bindings 4 and 5 follow the masks precedent: declared unconditionally so one bind group layout serves every generated shader, bound to 1x1 placeholders when no stock is loaded. Both are interpolated by hand with textureLoad -- this pipeline binds no sampler, and adding one for two lookups would cost a binding in every shader. Uploads are keyed on content so an unchanged stock does not push half a megabyte across the bus per frame. The end-to-end test earned its place immediately: it found the density lookup being filled z-fastest while a 3D texture upload wants x-fastest, so the red and blue axes were transposed. Green matched exactly, which is what that bug looks like -- a plausible photograph of the wrong colour, and one that every unit test on either side of the seam passes. dr-film now pins the layout in a test that needs no device, and states it where the field is declared.

dtourolleandClaude Opus 5	b6a95e1965	Simulate a film stock from its measurements, not from someone's grade ... FR-DEV-3f asks for look emulation and proposes HaldCLUT import to inherit the free film-simulation ecosystem. This takes the other road for the stocks where the measurements exist: run the physics. A stock here is its manufacturer's own datasheet -- spectral sensitivity, characteristic curves, dye densities. Light exposes three emulsion layers, the layers develop to densities, the densities are dyes that absorb, and what is left is what reaches the eye. A colour negative comes out orange and upside down because that is what a colour negative is; it becomes a photograph when a paper profile prints it, with the enlarger's filtration solved rather than dialled. What that buys over a LUT is that the parameters stay physical. Opening up a stop moves the picture along the film's real characteristic curve, shoulder and all, instead of scaling a number baked at one exposure. The data cost runs the other way too: a stock is 17 kB of published measurements where one HaldCLUT is 800 kB of one person's grade. It looks like it needs a spectral integration per pixel. It does not, and that is the whole design: - Exposure is a 3x3 matrix. The reconstructed scene spectrum is linear in the sRGB triple, so the integral collapses into nine numbers, exactly -- no approximation. - The characteristic curve is three 1D functions, sampled exactly. - Everything after that -- dye absorption, the print through the negative, the paper, the viewing illuminant, the adaptation -- takes exactly three numbers in, so it bakes into one 32^3 lookup. Per pixel: a matrix multiply, three curve taps, one fetch. Splitting the curve out of the 3D lookup rather than baking one LUT over exposure is measured, not assumed: the curve carries the sharp shape and the dye mixing is smooth, so folding them together would need three times the resolution for the same error. At 32^3 the worst error is 0.003 in linear sRGB, under one 8-bit code value, and a test says so. No wgpu dependency, deliberately, and the same isolation argument dr-lens makes: the model is plain f32 with a documented layout, so every property worth asserting is asserted on the CPU. Binding it to a texture is dr-gpu's job and is not done here yet. The expected values in tests/ came from a Python prototype running against a different colour-science stack. Agreement to three decimals is evidence about the model rather than about one implementation of it -- a transposed matrix or a mispasted observer row would pass every unit test and fail that one. Profiles are converted from spektrafilm by Andrea Volpato, CC BY-SA 4.0. The converter is in the tree and runnable, so what was changed from upstream is auditable rather than taken on trust; profiles/CHANGELOG.txt records it, including the one deliberate deviation -- Mallett & Yuksel's 1 kB basis instead of Hanatos's 4 MB table, which costs accuracy at the gamut edge and saves four megabytes.

dtourolleandClaude Opus 5	940058c78a	Keep git-lfs's own hooks, now that the hook path is ours ... `core.hooksPath` points at `.githooks` for the traceability hook, and that redirects *every* hook — including the four git-lfs installs for itself. They were written there by `git lfs install` and left untracked, which is the worst of both: present for whoever ran it, absent for everyone else. `pre-push` is the one that matters. It is what uploads LFS objects, so without it a push can land a pointer on the server with nothing behind it — which is exactly the failure CI has been hitting from the other side, and not a state to risk creating by accident. Committed rather than regenerated per clone, because `git lfs install` writes to `.git/hooks` by default and would miss the redirect entirely.

dtourolleandClaude Opus 5	dce1e66746	Show which cell a shift-click is measuring from ... The gesture had a hidden operand. A range runs from the anchor — the last cell plainly clicked — to the cell shift-clicked, and nothing on screen said which one the anchor was. A user who could not tell where the range was being measured from had no way to predict what it would take and no clue why a wrong one came out wrong; often the anchor is not on screen at all, which is itself the answer to "why did that select so much". The anchor is marked with an inner ring, drawn inside the selection ring rather than in a colour of its own: it has to stay legible against a thumbnail of any brightness, and a hue would read as a second kind of selection. It is an ordinal, so it marks a row only while the photograph it names is in the loaded window — off screen it marks nothing, which is the honest answer, and `anchor` rides in the cell model beside `selected` so both are pushed by the one pass that already keeps the grid in step with the selection.

dtourolleandClaude Opus 5	54f9cb54fb	Take the whole run a shift-click names, not the part that happens to be loaded ... Shift-clicking two photographs selected only the cells between them that were in the loaded window. The grid is a window of a hundred or so over a library of twenty thousand, and `apply_press` resolved the range against that window — `ids[lo_row..=hi_row]`, clamped to what was there. Everything else in the run had no id anywhere in the UI, so it was silently dropped. The user cannot see that: the selection count is off screen along with the photographs, and the gesture only announces itself when the drop files a dozen images instead of two hundred. The two ends are *ordinals*, and only the catalog knows what lies between them. `read_ids_span` asks it, through the same predicates, the same rating filter and the same ordering the window itself is read with — an ordinal names a photograph only relative to an ordering, so a run taken through any other one is a run through a different library. That ordering is now a constant, `GRID_ORDER`, shared by the window, the trash's own order beside it, and the run: capture time first, with the file name breaking ties and nothing more. A card written by two cameras interleaves names that have nothing to do with each other, and what "everything between these two" means to a photographer is a stretch of an afternoon. The query is reached through a closure handed to `CollectionsController` at wiring time rather than a catalog handle, because the scope and the filter that bound the run belong to the grid's controller. `apply_press` stays a pure function of what it is given, which is what keeps the selection rules testable with no library open — and the tests pass a run that reads a plain slice. Where there is nothing to ask, the loaded window is still used: a poorer answer than the catalog's and a far better one than a gesture that appears to do nothing.

dtourolleandClaude Opus 5	22325415b1	Fetch what is on screen before what is not ... The other half of the blank bottom row, on a library still filling its thumbnail store: the cells were in the model, and nobody had asked the server for them yet. A batch is fetched one image at a time, two round trips each, and it is abandoned wholesale the moment the window moves. Issued in model order, the front of that queue was the quarter-window of cells sitting *above* the view — which nobody is looking at — and the back of it was the bottom of the screen and the screenfuls below. So the last rows of the grid waited behind three quarters of a window's worth of fetches for photographs off screen, and every scroll threw the queue away and started over from above the view again. For as long as the scrolling continued, the bottom of the grid could be starved. The rows still address the model they were built against; only the order they are asked for in changes. On screen first, in reading order, then the rows below the view, then the rows above it. Below before above because that is where the view is going — scrolling back over cells already fetched is served from the store, and from `requested` without a fetch at all.

dtourolleandClaude Opus 5	7c8e433911	Load the window around the whole view, not around its first cell ... The bottom row of the grid was often blank, at a scroll position the user could sit at indefinitely. Two numbers decided when the loaded window follows the view, they lived in different languages, and they disagreed. The grid loaded three screenfuls and Rust held the window still until the first visible cell was three quarters of the way through them. Three quarters of three screenfuls is 2.25, and the view itself is one screenful tall — so the bottom of the screen had already travelled a quarter of a screenful past the last loaded cell before anything moved. Those rows are not in the model, so nothing is drawn for them. The same margin was wrong upward, and exactly so. The window is placed a quarter of itself behind the view, and the margin then declared the view too close to the top at precisely that distance: every single row scrolled upward re-read the catalog, rebuilt all 360 cells and re-queried their badges and ratings, and so did the row after it. So the grid now reports what it shows — a screenful, counting the row the scroll position has cut in half, which `visible-rows` alone undercounts and which is exactly the row reported missing — and Rust owns the rest: four screenfuls loaded, placed a quarter back, and moved once the view comes within half a screenful of an edge of them. One decision in one place, and the test now walks the view the length of the library and asserts the window covers it at every step.

dtourolleandClaude Opus 5	33847a0bbc	Open one GPU device for the tests, and stop the checkout dying over LFS ... Two CI failures, unrelated except that both were mine. **The test binary faulted under parallel threads.** Every GPU test opened its own `GpuContext`, and `cargo test` runs on as many threads as there are cores — so a full run asked the driver to bring up a dozen Vulkan devices at once and died with SIGSEGV. Serially it passed, which made it look like flakiness rather than a fault in the harness. One device now, behind a `OnceLock`: a `GpuContext` is an `Arc<Device>` and an `Arc<Queue>`, so sharing it is a refcount, and the losers of the race block until the winner is done. 416 tests now pass in parallel, in half the time twenty-six devices took. **`lfs: true` on the checkout made the checkout fail.** The intent was right — the model is in LFS, a plain checkout writes a 133-byte pointer, and the build script panics on it — but on this server `git lfs fetch` is rejected at `/info/lfs/objects/<oid>` with a client error: the credential `actions/checkout` installs for git is not one the LFS endpoint accepts. So a fetch problem presented as a checkout problem and took the whole job with it. The object is on the server; a clean clone over SSH with `git lfs install --local` pulls all 11 MB of it. It is now its own step with an explicit token, and `continue-on-error` so a credential problem cannot masquerade as a broken checkout — if it fails, the build still runs and fails with the build script's own message, which names the real problem.

dtourolleandClaude Opus 5	a3785ba55d	Say which version this is: 0.6.0 ... Set by tools/set-version.sh, which is the only thing that should. The workspace, the pacman package and — through Cargo.toml at link time — the APK all state 0.6.0, so a bug report naming a version names one commit.

dtourolleandClaude Opus 5	6b5ffc6a93	Anchor the delete on what the view was showing, not on the window's start ... The grid still jumped. Anchoring on `offset` was wrong for a reason this file already states, a few hundred lines away: "the first *visible* ordinal, not the window's start: the loaded window deliberately begins a quarter of a screen above the view, so its first cell is one the user cannot see." Two things made `offset` the wrong number. It is a screen-quarter above what is being looked at, and by the point this runs it has already been re-clamped against the new, smaller total — so seeking to it moved the view somewhere the photographer had not been. A smaller jump than the original, and the same fault. `resume_at` is what the grid last reported as its first visible image, which is the photograph the person is actually looking at.

dtourolleandClaude Opus 5	cd64166b15	Keep the view on the photographs after some of them are deleted ... Deleting made the grid go blank and jump somewhere arbitrary. Two causes, both of them the viewport being left behind by everything else that moved. The Flickable is sized to the *whole* library so its scrollbar is a real address into twenty thousand images. Delete some and that content gets shorter, which leaves a view near the end scrolled past what now exists — cells sitting above a viewport looking at empty space. Slint does not pull a Flickable back on its own. (The clamp for that went in with the previous commit.) The jump is the other half. Cells are drawn at their absolute place in the library, `(i + offset) / columns`, and a delete re-clamps `offset` downward so the loaded window still fills. Nothing touches `viewport-y`, so the same scroll position now addresses different photographs and the grid appears to leap somewhere unrelated. `restore_position` re-anchors on the ordinal the view was showing, clamped into what is left. Not on the deleted image's own position, which no longer exists, and not on the top of the library, which would throw the scroll position away on every delete — after removing one frame from a wall of twenty thousand, the one you want next is the one that just moved into its place. Only on a shrink, and the shrink is detected by reading `library-total` before overwriting it. Re-anchoring on every load would fight a scrub, which sets exactly this property to go where the user asked.

dtourolleandClaude Opus 5	fa4ad6e2d6	Drag the date range on the axis it is chosen from ... The range could be turned on with a finger and not aimed with one. Its two ends were typed as `YYYY-MM-DD` into 108px fields behind a soft keyboard, to name days already drawn on the axis a thumb away; and the chip that seeds them takes its span from the timeline's zoom and pan, which are a wheel and a middle button. A touch screen has neither, so on Android the filter was a switch with no aim. The band is now on the timeline. Two ends with grips, dragged along the bars, released to filter — the histogram was already how a period is found, and this makes it how a period is stated. Both ends snap to whole days, which is what the typed fields mean, what `show_range` reads back out, and a floor under a range dragged shut. The fields stay for what dragging cannot do: name an exact day, and say in words what the range is. For that to work the axis had to stop following the range. Redrawn to the band, it moved the ground under the very handles doing the narrowing, and there was nothing outside the range left to widen back into. While there: a fixed number of equal bins instead of calendar buckets. Between one calendar unit and the next the bar count is free to wander by a factor of twelve, so zooming in halved it two steps out of three — the same picture drawn wider until it jumped back to fine. Equal bins also include the empty ones, so a bar's position on the track and the date under it are finally the same quantity; before, a library with gaps drew a February six months wide and the marker, the band and a click all pointed somewhere else. The count is a setting, 32 or 64, because the right answer is a question about the screen. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-23 18:42:42 +02:00
dtourolleandClaude Opus 5	b0b6dd559a	Show what is selected, and let a collection be made of it ... Three things a selection needed and did not have. **Seeing it.** The count existed — "12 selected" — in the header row, which scrolls sideways. On a tablet it sat past the right-hand edge along with every button beside it, so a selection was something you could make and then not see. A selection you cannot see is one you act on by accident. **Putting it down.** The only way to clear one was "Done", which also leaves select mode — so after filing forty photographs the next forty began by re-entering a mode the user had not meant to leave. Clearing is now its own action and keeps the mode. **Filing it somewhere new.** Making a collection of a selection took four steps: create one, find it in the tree, select the photographs again because creating it changed the scope, then add them. It is one press, which is how a selection is usually meant — it is gathered *because* it is going somewhere. The new collection is created at the top level rather than inside the current scope, unlike the tree's "+". A selection can be gathered from anywhere, including across collections, so filing it under whichever one happens to be open would put it somewhere its contents did not come from. It opens straight into its name field, for the reason `collection_new` already does: the placeholder name is nobody's choice, and making the user find the rename afterwards is asking them to finish a job we started. All of it on its own strip beside the date range's, appearing only while there is a selection — the third control this session that was invisible for being put in a row that scrolls.

dtourolleandClaude Opus 5	ffc40c42d2	Regenerate the matrix where the tags are changed, not after the push ... The traceability gate has failed on six commits in a row, every time for the same reason: someone added a `TRACES:` tag and did not regenerate docs/traceability.md. The gate is right to fail — a matrix that disagrees with the tree is worse than none, because it is read as current — but it says so after a push, on a commit that is otherwise fine, and by then the tag and the matrix are two separate things to remember instead of one. A pre-commit hook regenerates it and stages it, so the two travel together. Enabled with `core.hooksPath`, which is a local setting: run git config core.hooksPath .githooks in a fresh clone, or the hook sits there doing nothing. Only runs when something that can carry a tag is staged, and says nothing unless it changed the matrix — a hook that prints on every commit is one people start passing `--no-verify` to. If the report cannot run at all it leaves the matrix alone and lets the commit through: refusing to commit because a build is broken would be a worse failure than the one it prevents.

dtourolleandClaude Opus 5	f9c7aba8b6	Regenerate the traceability matrix ... Six commits added nineteen TRACES tags between them and none regenerated the matrix, so the gate failed on every one of them — including the commit the release tag points at. The gate is doing its job: a matrix that disagrees with the tree is worse than none, because it is read as current. Coverage is unchanged at 50.3%; what moved is where each requirement is tagged, which is the half of the file that is actually consulted.
