Measured with RawNIND on a 20.8 MP raw: an Apple M3 does a tile in 116 ms, an
RTX 3060 Ti over Tailscale 345 ms there and back; sharing blindly made the
export take 34 s instead of 6.4 s while the photo waited for the server's last
tiles. The greeting now times a check tile there and back, and tiles are
shared only when that beats this computer's own time per tile (the card's, or
the CPU's with its threads counted as `card_is_faster` does). Otherwise
`denoise.status` → `device.remote` says `slower` with both times. With the
server configured but slower the export takes 7.2 s (greeting + check tile).

Zoomed in, each view's photo reaches past its pane. The whole-frame renders
were drawn unclipped (only the window renders were clipped to their pane),
so the After's magnified whole-frame render covered the Before pane's margins
and the gap between the panes with a blurred picture, and the Before side
looked like it didn't fill its pane. Both whole-frame renders are now clipped
to their pane, like the windows over them; the Before / After labels stay
under the pane instead of moving off screen with the photo's bottom edge.

Generated with Codex.
- `lightcraft_denoise::remote`: protocol v1 over TCP (JSON lines + byte-shuffled,
deflated half-float tiles), a `Remote` client (connection pool, four slots,
greeting checks the model's SHA-256 and tile size, gives up after three failed
tiles) and `serve` (shared token compared in constant time, size caps including
payloads that inflate past their tile, connection limit, timeouts).
- Engine: with LIGHTCRAFT_DENOISE_URL / LIGHTCRAFT_DENOISE_TOKEN set, the loaded
model greets the server on first use and adds its slots to this computer's
tiles at once; a tile goes to a free server slot, else runs here, and a tile
the server fails runs here too. `denoise.status` → `device.remote` says where.
- `lightcraft-cli denoise-serve` serves the installed, selected model on this
computer's card (checked against the CPU, as in the app) or CPU.
- docs/denoise.md: setup, safety (unencrypted: VPN/LAN only) and the protocol.
Tested: protocol round trips, refusals (token, model, tile size, hostile
payloads), fallback and give-up; the engine model with a live, a mismatched
and a dead server; the CLI binary serving a synthetic model end to end.

- New crate lightcraft-slideshow (L1, no UI): SlideSettings (margins linked or
independent, guides, aspect preview, zoom to fill, stroke border, cast shadow,
backdrop colour, colour wash, background image; lengths relative to the slide's
shorter side; validated and clamped) and a CPU compose() used by playback, the
Settings preview and slideshow.preview.
- Engine: slideshow.layout (partial merge, saved in prefs.json) and
slideshow.preview {id?, width?, height?, path?} (PNG to path or base64);
RenderJob::with_slide composes on the render worker; the background photo is
rendered once and shared.
- Playback: with a non-default layout each slide is the composed screen-sized
slide, prepared ahead like before; the default layout plays as before.
- Settings > Slideshow: Layout, Options and Backdrop sections and a debounced
live preview of the active photo's slide (with margin guides).
- Tests: composer geometry/pixels/hostile input, command get/set/persist/preview,
headless playback of a composed slide and of the default layout.
The 2668-entry table read off the black-box oracle's output is gone.
arw6_curve.rs now builds the 4096-entry table at first use from our own
measurement: piecewise linear through knots u_k = 128 k, c_k = u_k for
k <= 11 and 356.89 + 655.646 ln(k - 6) above, rounded half up, fitted to
the 7 same-exposure lossless (LJ92) / ARW6 pairs of the CC0 ILCE-7RM6 set.
A unit test pins the whole table (sum 27776336, weighted 92792980288),
its anchors, the identity through 1408 and strict monotonicity.
The corpus sums become regression values of the new output; the 12-bit
codes before the curve stay verified against the oracle (Phase 0).
docs/arw6-compression.md describes the curve, how it was measured, its
uncertainty, the structure and x2-scale evidence, why it is not in the
file, and the after-the-fact comparison with the oracle's curve; the
tracker and docs no longer call the output bit-exact against LibRaw.

docs/superpowers/ held the working spec and plan, which pointed at the
local plan/ folder. The ARW6 module docs now cite the sections of
docs/arw6-compression.md, which gains the facts they relied on from the
spec: the NP field of word 0, the stream header word layout and how the
first half's residual lines are counted.

`cargo xtask corpus --download` now fetches one full-frame Compressed and
one APS-C Compressed HQ file (about 94 MB) instead of all 12 (about
630 MB); the corpus test checks those two and the lossless-sibling
regression test is gone, since nothing would download those files.
docs/arw6-compression.md keeps the full table with source paths and
SHA-256, says which two xtask fetches and how to fetch the rest with
`curl -L`, and records the CC0 1.0 statement of RawDB's set record
(accessed 2026-10-10).

The RawDB entries in xtask carry their SHA-256 as the third field, which
`cargo xtask corpus --download` checks; the corpus test keeps only the
sensor sum checks.

Previews looked more saturated than the exported files on Mac screens. The
pixels are the same: preview and export match to within one level on the CPU
and GPU paths, and exports embed a correct sRGB profile. But wgpu leaves the
window's Metal layer without a colour space for sRGB surfaces, and Core
Animation shows such a layer without colour matching ("If nil, no
colormatching occurs", CAMetalLayer.h). On a P3 screen the sRGB previews
were therefore shown too saturated, while Preview and Photos convert the
exports properly.
While no monitor profile is chosen in Settings > Display, the desktop app now
shows previews through the profile of the screen the window is on
(NSWindow.screen.colorSpace.ICCProfileData, safe objc2 calls), through the
existing display-profile path. It is read again about once a second, so
moving the window to another screen is followed. A chosen profile still wins;
"Use Screen Profile" goes back to it. app.displayProfile reports it as
path: null, screen: true. Other platforms and headless sessions are
unchanged.

The highlights/shadows base (fast guided filter of log luminance, eps 0.35)
followed thin high-contrast detail, so the per-pixel shift flattened twigs,
lines and texture in bright areas (and dark ones under Shadows); Exposure
kept them.
This changes how every existing edit with Highlights or Shadows renders, so
it ships as a new rendering process (docs/process-versions.md):
- Process::V2 (version 2) is added and made LATEST. New photos and Reset get
it; existing edits stay on V1 until Update to Current Process. Settings
saved without the field still load as V1.
- From V2 the base is the same guided filter of a separable median of log
luminance (radius 0.15 % of the long edge, <= 24 px): fine detail takes its
surroundings' shift and keeps its contrast, region steps stay put (no new
halos). V1's base is untouched: local::tone_base_detail is 0 under V1 and
tone_base then is exactly guided_fast(l, sigma, BASE_EPS), as before.
- CPU (local::prepare) and GPU prepare (median_h / median_v kernels, bit for
bit with the CPU median) both branch on it via PlaneSigmas::base_detail.
- The base plane's cache key is now (sigma, process, median radius)
(local::BaseKey), so a warm cache never serves one process the other's
base. plane_at is shared with the GPU crate.
- finish::base_tone: V2 uses V1's tone map.
Tests: V2 keeps twig/local contrast (>= 0.9 of Exposure's) with no halo; V1
plane sigmas have no median and its base equals guided_fast bit for bit; V1
and V2 render alike without Highlights/Shadows; warm-cache renders across
V1/V2 switches equal fresh ones (fails if the key drops the process); GPU
matches CPU on both processes at 720 and 2400 px, cached and not.
Pentax 645D 2401 at 4000 px: main and V1 renders bit-identical (plain,
Highlights -100, Shadows +100). Highlights -100 bright rel. detail
0.095 (V1) -> 0.147 (V2), Exposure -1: 0.124; Shadows +100 dark rel. detail
0.126 -> 0.148.
RENDER_CACHE_VERSION 54 (adjust at merge).
A keyword made from Keywords' + is shown (the section and its parents open); a
press on a header button never starts a section drag; a section dragged to the
top edge scrolls past a pinned header again (only a drag picked up by the
pinned header waits until it has left it). Tests that could not fail are
replaced, and the parity rows say what the code does.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Albums' + is no longer a special case of the header: header_button says which
section has a button and whether it acts or opens a menu, and the frame draws
it in the header and its pinned copy.

Every dialog but Import draws its options in a vertical scroll area capped at the
window height minus the title bar, frame and button row (measured on the previous
frame), so on a 1366x768 screen the Export dialog's title and Cancel / OK stay on
screen. Dialogs that fit keep their size. Lists that scroll on their own (What's
New, All Metadata, shortcuts, smart-album rules, credits) get shorter first rather
than scrolling inside a scrolling dialog. Import keeps its resizable window.
An album or photos released on the pinned Albums header went to the row
scrolled under it. Folding from the pinned header keeps the sideways scroll,
its hand-off to the next frame can't go stale, and a section picked up by the
pinned header doesn't start scrolling at once.

Their confirm does nothing, so they join About, Shortcuts and Settings in the
footer's informational list: one Close, no Cancel / OK. System Info keeps Copy
to Clipboard; Esc still closes them.
Pinned header at the top of the sidebar, hairlines between sections, the fold
chevron in the rows' triangle column, a count on folded sections, fainter zero
counts. From review: a move nobody could see is no move, ui.set refuses
`sidebar` together with `collapsedSidebar` and unknown names in the latter.
Translations and What's New for the sidebar work.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
view.sidebarMoveSection; a section with nothing to list stays with a note
instead of disappearing (so every move is one you can see). ui.set reads
`sidebar` strictly and still takes the older collapsedSidebar list; an album
folder's triangle and row can no longer toggle twice in one click.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
view.sidebarSection / view.sidebarReset; the same list opens from a section
header's and the My Photos title's context menu. A new album brings a hidden
Albums section back.
