Nothing read EXIF orientation, so every frame from a body held sideways
lay on its side — in the grid, in develop, and in the read-only preview.
The tag is honoured as part of *reading the file*, at the same standing
as a RAW's masked-photosite crop, never as an edit. It lives as a
baseline on Framing rather than as a starting value for quarter_turns,
which is what keeps four things true: a sideways file opens unmodified,
reset returns it to upright rather than to the sensor's scan order, its
sidecar stays empty, and the rotate button still moves the image 90°
whatever the file underneath it says.
Framing::effective composes the baseline with the user's own turns
through the group law rather than by adding turns and OR-ing flags. The
naive version gets one case wrong — an odd baseline turn plus a user
mirror — and gets it wrong quietly, because the result is still a
plausible orientation. The composition collapses to a single
permutation, so obeying the tag costs nothing per pixel.
dr_decode::orientation is a header-only IFD walk, separate from
metadata() for the reason the entry points are separate at all: the grid
asks once per cell and must not build a rawler decoder to get one tag.
CR3 and RAF fall back to the full read, being neither TIFF nor JPEG.
Written down as FR-DEV-3h.
Known gap: thumbnails cached before this stay sideways. The store is
keyed by file and size, and its shards sync — invalidating them would
have every client re-download 25 MB a shard, which is not this commit's
call to make.

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

Remote browsing must not transfer whole RAW files. The obvious shortcut —
fetch a fixed prefix and hope the preview is inside — does not work: an
embedded JPEG typically starts a few hundred KB in and runs for one to three
MB, so a truncated fetch yields a JPEG whose scanlines stop partway down.
Decoders render what they have rather than erroring, so the failure looks
like a corrupt image rather than a short read.
This reads the TIFF-structured containers — CR2, NEF, ARW, DNG, ORF — and
returns an exact byte range for a Range: request. CR3 is ISO-BMFF and
declines to the caller's whole-file path, which is correct if slower; a
locator returning a wrong range would be far worse than one that declines.
Every offset read from the file is bounds-checked against the real file
length rather than trusted (NFR-SEC-1).
