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.

Progress docs per craftrules standards/progress-docs.md: target-app parity, gaps, roadmap with alpha gate, readiness by audience (full / mainstream / essentials) with Opus 5.5 hours, model-by-model RAW coverage against Adobe's camera list (docs/raw/), and format, hardware, UI and localization parity docs.

Merge origin/main into #480 and apply the review:
- the Samsung-with-a-Pentax-maker-note -> PEF rule now also needs raw evidence; its test fixture
gets a CFA photometric, and the same RGB file without it is not a raw;
- for the Pentax family the Exif CFAPattern (0xa302) counts as raw evidence, as main's PEF reader
takes its layout from it (uncompressed / PackBits PEFs);
- Samsung's private raw compressions 32769..=32773 count for SRW (NX1 / NX500 use 32773);
- the engine fallback in files.rs is dropped (main's version kept): a corrupt raw without a
preview stays an import error; the engine regression test for camera-authored TIFFs is kept.

Merge origin/main into #555. The decode_hasselblad doc comment records how the coding rule was
established (first hypothesis recalled by the AI author from training data that includes other
converters, corrected for byte order and confirmed by a black-box search over 17,280 layout
hypotheses on the CC0 files; the code is original). The LR-IMP-FORMATS row on main's text now
lists the decoded FFF and lossless-JPEG 3FR files instead of preview-only. RENDER_CACHE_VERSION
37 -> 38.

Main's reconstruction (#607) replaces this branch's rewrite of highlight::reconstruct. Kept from the
branch: develop_binned_masked (clipping decided per sample before averaging) and the denoised twin
using the same mask. New: highlight::reconstruct_masked, #607's reconstruction with the clipped
channels told by the mask (block means as lower bounds), shared with reconstruct_with through a
generic clip test (no slowdown on full-size images), and CameraColourModel::rebuild_highlights_masked
so binned previews keep the colour model's clipped white. RENDER_CACHE_VERSION 38.

CLAUDE.md gains the rule (a TaskGuard for every job that runs off the UI
thread and can take more than a moment; no progress window, panel or
toast of its own), and docs/background-tasks.md says how: kind, label,
progress, units, detail, the three ways to cancel, examples and tests.
Photo Merge's and the face scan's docs no longer describe the old
progress toast.

Merge origin/main into #560 (fit_preview / camera-look refactors of #528, #583, #568, #616).
`starting_colour` now tries the per-file camera-JPEG fit (with the camera profile when there is
one) first and uses the spectral-sensitivity matrices only when that fit fails, before the neutral
fallback, so no photo with an accepted JPEG fit changes. Tests pin the order through an injectable
fit; docs, parity, ROADMAP and what's new describe it. RENDER_CACHE_VERSION 37 -> 38.

Synchronize Folder (#604) shows its scan ("Looking for changes", while
its dialog is open) and its run ("Synchronizing folder") as rows: the
scan's cross stops it and closes the dialog, the run's stops it like
Cancel did (what was done stays, as one undo step; the end says Stopped).
Its progress window is gone. The contact-sheet PDF export (#563), which
went through the export task already, gets a test for its row.

Only proxies of raws that take the per-file camera look (Photo::relative_wb) go stale: JPEG/PNG/DNG proxies are never rebuilt for the look. The opening scan runs once per LOOK_VERSION (a look-version marker in the smart previews folder), not at every library open; Build Smart Previews still refreshes stale proxies. Each proxy is checked and written under one lock, so the background refresh and library.smartPreviews never write the same file at once. LOOK_VERSION 2: main's DRO / ILCE-7CR camera-look changes (#528, #583, #568, #616).

Main (#575, #580) rewrote default_crop. The image crop now keeps main's
order for every Sony body (Sony's crop tags, then DefaultCrop, then the
recorded-size crop), so framing does not change. Only the ILCE-7RM4A
distortion warp takes its centre and normalization from DefaultCrop when
the file has one, which keeps the geometry validated against Sony's
exports (centre x 4783.5 on the A7R IVA sample). The DNG round-trip test
now checks both: Sony's crop on the image, the warp centred on the
default crop. RENDER_CACHE_VERSION 38.

Main's SR2SubIFD white balance (#575) already reads the A900's applied
levels (2688 / 1024 / 1024 / 1516, the same 2.625 / 1.480 gains), so the
hard-coded maker-note 0x0020 block at offset 188 is dropped. The centred
crop now goes through #580's recorded_size_crop (a `centred` flag, only
for the packed 12-bit layout); every other body keeps main's framing.
Adds the CC0 A900 sample to the corpus with checks for its white balance,
black level, bit depth and crop. RENDER_CACHE_VERSION 38.

A cross clicked in the frame its task ended no longer puts "no task N"
in the status bar: the row's cancel goes to the engine directly instead
of through the app's command runner, which reports every error there.
The face-scan row test scans demo photos no other scan test uses, so it
no longer joins the scan deadlock of #630 (with one of the existing pump
tests it hung 13 of 20 runs; now 0 of 20).

LR-BEHAV-BG-TASKS now cites activity.list / activity.cancel and lists
every job on the stack; the import and Build Previews rows no longer
describe progress windows and toasts; a what's-new entry.
Fixes the stack not growing when tasks arrive while it already shows a
row (an egui area lays out in last frame's size, and the scroll area took
that as all the room, so later rows were cut off), and adds the Russian
"Quit Anyway".

Find Missing Photos shows a row (a sweep: the amount of work isn't known,
no cross) while it searches; the auto-import folder listing, which runs
every few seconds, stays quiet.

While a photo's AI Denoise picture is being made or waits its turn, the
stack shows "AI Denoise" with the running photo's tiles as a percentage
and its file name (no cross: what is made follows the Denoise amounts and
Settings). The row goes when the queue is idle.
