The ring said which folder a reading was asked of by taking the row's own
name apart and comparing the pieces, which is the same path spelled twice and
only nearly the same. When the two spellings drifted the asked row never
matched, and the fallback that used to carry the mark on the roll's row had
gone, so a reading ran with nothing on the column at all.
The mark is now built with the key the walk gives the row — `folder/sub`,
through `normPath`, the same way a frame id is spelled — and a reading whose
own row is not on the column (a branch folded away, a folder gone from the
disk) falls back to the roll's own row, so a reading is never invisible.
The column's ring was drawn from the open node's roll: a row of another roll
had no path under it, so the empty prefix matched every row of the roll being
read and the whole column lit up. The roll's own row was marked too, at every
moment of a reading of it, and a reading kept to one folder counted its frames
onto the roll's row as well — a roll counted down to one branch of itself.
A queued request was drawn from the reading's roll instead of its own, so a
request on a second roll showed nothing at all.
A reading this window holds hands each frame over the side as it stores it,
and the screen puts those rows into the strip on a half-second debounce. The
reading ends before that debounce fires, the screen reads the catalogue back
— and that read already carries the frames that were handed over, so the
rows still waiting are appended to a strip that has them: five files of a
plain JPEG folder read "10 photos", the album row read 10, and the strip drew
two tiles for every frame, one of them keyed the same as the other.
Measured on five JPEGs: header 10, album row 10, ten tiles of five ids. The
store held five rows and the reading reported 5/5 new frames the whole time,
so the count was the screen's alone. A second pass over the same folder read
five, because its read-back landed last.
The id is the frame, so the append now skips what the strip already has.
Same folder after: 5 photos, album row 5, five tiles of five ids, and no
duplicate-key warning from React. Six RAW bodies and the studio are untouched:
the fix is inside the catalogue screen's own row append.
Skia's Image.MakeImageFromEncoded applies the embedded JPEG's EXIF
orientation itself. A Panasonic RW2 preview stored 1920x1280 with
orientation 8 therefore decodes as 1280x1920 already — the frame the
camera meant.
previewGrid turned it a second time by its own per-orientation canvas
rotation, so a portrait frame's reference grid met the develop a quarter
turn out, previewMatch rejected the fit as folded and the RW2 opened with
no tone curve at all (~9-13 levels off across the shadows).
Drop the rotation and read the crop rectangle and aspect straight from
bmp.width()/bmp.height(), the display dimensions Skia hands back.
Panasonic RW2 now fits a real curve (dRGB 2.3,-0.0,0.4, was -9.1,-10.3,
-13.2). The five bodies that were already stable — ORF, NEF, DNG, both
RAF — measure exactly as before.
getJpegOrientation had no other caller and goes with it; raw-orf-check
drops its own byte-scanning preview finder, which crashed on DNG and RAF,
and reads the reference through the shipped extractEmbeddedJpeg.
A HEIC is the one camera file no engine on this platform will paint:
Chromium answers createImageBitmap with InvalidStateError and its
WebCodecs take no hvc1 still, and unlike a RAW there is no JPEG preview
inside to lift. It is decoded in software instead, by libheif built to
wasm, in a worker of its own — so a folder of them reads without the tab
stopping for a second, and what leaves the worker is the same JPEG
developRaw hands the studio. Nothing downstream knows the difference.
Into the studio it goes on the same terms as every other frame: dropped,
picked, or opened from the catalogue, no tier asked and the engine's own
colour untouched. The frame's date, ISO and position come off the HEIC
itself, which is passed along as the bytes the stamps read.
The catalogue's tile does not pay the decode: a phone writes a small
HEVC copy of its frame as an item of its own (thmb, 320x240 on an
iPhone), reachable only by walking the container by hand, and it decodes
in milliseconds where the frame takes a second — from the same 256KB the
catalogue already reads for a header.
The shelves themselves now want an account: a guest gets the note and
the way in, and the scan never starts.
VT323, Alex Brush, Tilt Warp, Hahmlet, Pinyon Script, Allura, Dancing
Script and Amatic SC join the two the bundle already carried, each
subset to the same latin / latin-ext / vietnamese ranges and pinned to
its upright 400 instance where it is variable.
The bar under the picture is the grid it needs to be: equal free tracks either
side of the two buttons land them on the picture's own centre whatever OPEN and
the stars measure, and the pair keeps the ends it does not own. Under 700px the
stage is too narrow for one line, so the bar wraps as it did and the lines it
wraps to are centred.
The frontend image carries the library's quarter turn (catalogue `rot`, the
two chips under the preview, the wall and strip tiles, and the studio's
write-back), stamped 2e06e5a at the foot of the rail.
The library stage carried no way to correct a frame shot on its side, and
nothing kept the correction. A quarter turn now rides on the catalogue row
(`rot`, beside `star`, carried over by a rescan), the two chips under the
preview step it, and the tile, the strip thumbnail and the stage all read it
through one bake so a frame is never stood on its side in one place and
upright in another. The studio opens a frame at that angle and a turn made
there is filed straight back onto the row, so either end of the turn is
what the frame comes up at next time.
libraw-wasm moves the buffer it is given into its worker, so raw.open() detaches
the caller's array. developRaw read its embedded JPEG preview as a view of that
same array, so the open emptied the preview, Skia rejected the detached buffer
and the catch returned the emptied preview as the develop - every RAW opened from
the LIBRARY reached the studio as 0 bytes and the app said "Could not develop
this RAW file. Try again, or use its JPG."
Hand the worker a copy instead, in the develop and in the thumbnail path. The
EXIF stamps read off the caller's bytes afterwards are intact again.
The ORF check now hands the bytes over in the transfer list the way the package
does, so it fails on any develop that forgets this.
