3dtours 31435aac77 web: the offer to install is made once, and the answer is kept 2026-10-01 07:46:10 +07:00
3dtours 166a677590 light: the tone ramp is four bumps on the identity, not straight segments between five knots — a knot is an angle, an angle in a tone curve is a Mach band, and the wedge reads the seams: BLACK +100 broke at 0.030 with 105 of second difference, HIGHLIGHT -100 at 0.747 with 72
The ramp was a0..a4 with the pixel's base interpolated straight between them.
A segment meets its neighbour at an ANGLE, and the second derivative of a tone
curve is what a gradient reads as a band — so a knob left a line across the
mid-tones, worst exactly where it was reported: BLACK +100 put its whole lift
inside 0.25 and the stretch from 0.25 up came back identical to the untouched
frame (the "transition stays grey" it was reported for), and HIGHLIGHT -100
folded a seam into 0.747, between the highlights it pulled and the shadow it
left under them.

Measured on a 1024-step luma wedge through the exported pass, second
difference through a ±1% box: BLACK +100 read 105 at 0.030 against 0.000 from
0.25 up, HIGHLIGHT -100 read 72 at 0.747. Step of the first derivative across
the knots: 0.955 at 0.25 and 1.146 at 0.75 — the curve arrived folded, and
1.146 is a sign flip, not a bend.

So each knob is now a BUMP on the identity, peaking on its own knot — BLACK on
0.00, SHADOW on 0.25, HIGHLIGHT on 0.75, WHITE on 1.00 — with the kernel
(1-u^2)^2 over a half-width (a half of the ramp for the two ends, whose knots
ARE the ends, a quarter for the two heads). Level at u = 0, so a knot moves
without a fold at its own top; level at u = 1, so a move lands on the identity
and on its neighbour without an angle; C1 everywhere between. The two bumps of
a half meet on 0.50 both on zero, which is the same fixed midpoint as before,
and DR still moves the same knots (0.12 on the toe, 0.18 on the head, half of
each on the heads beside them).

A sum of bumps can overshoot where two steep sides land on one stretch — past a
slope of 1 the curve runs BACKWARDS, a worse band than the seams this replaces,
and it is reachable: DR alone was under it, BLACK and SHADOW +100 together were
not (unguarded min slope -0.0141). The guard reads each pair at its own
steepest points, 8/(3*sqrt(3))/w per unit amplitude (TONE_BUMP_SLOPE_HALF 3.0792,
TONE_BUMP_SLOPE_QUARTER 6.1584), holds the two under one and gives them up
together past it. A single knob never reaches it (a full BLACK is 0.77, a full
SHADOW 0.77), so every slider keeps its whole travel; the worst case is DR at
full, which gives up a tenth of its head roll (0.18 -> 0.8376 on the head), and
BLACK with SHADOW both at +100, which arrive at 0.65 of their own lift instead
of folding. Guarded, the sweep over five levels of all four knobs and DR reads
a min slope of +0.0183 and a max of 1.9937, with the largest slope jump 0.00005.

After: the same wedge, the same pass. The knot steps are 0.096 at 0.25 and
0.478 at 0.75, with no sign flip — C1 across the knot instead of a fold. BLACK
+100 now carries the rework out of its own quarter: +0.139 at 0.25, +0.101 at
0.30, +0.033 at 0.40, 0.000 at 0.50, where it used to read 0.000 from 0.25 all
the way up. HIGHLIGHT -100 keeps its lift (-0.126 peak against -0.121 before) and
spends it over the quarter instead of into a line. Every knob on zero is the
identity to the last bit — the pass also runs for the stock split tones and for
DR alone — and 0.50 is still the one value no knob moves.

Checks: tone-base-check.mjs now runs the bump and the guard as arithmetic
beside the shader (with the negative control: the unguarded pair still folds,
the guard is what stops it). highlight-knee-check.mjs reads the kernel and the
two slope constants off the source, pins the four amplitudes and the guard, and
sweeps the travel of every knob as before. All ten checks that run without a
browser pass, build clean.

Skipped: the guard's ceiling is a constant, not a search for the widest travel
that still clears a band we cannot see. Add when a frame shows a band the
deflections in hand cannot explain.

3dtours 097e383b86 light: the tone base is a real blur, not nine point samples of one — the ring aliased the luma and the ramp painted the alias back as mottle
The base layer shipped last commit was nine POINT SAMPLES of the child, one
ring out at TONE_BASE_RADIUS. A ring is not an average, and on a frame with
texture at the ring's own scale it is worse than one: the nine lumas differ,
the sample pattern beats against the texture, and the base field comes out
aliased. The gain the pixel then rides, o(base)/base, is a function of the
base with a kink at every knot — so each alias of the base becomes an alias
of the gain, and the reconstruction paints it straight back over the detail
it was supposed to leave standing. Reported on a waterfall: grey patches
loose on a mountainside, a smear across the face of the falls, and plateaus
in cloud and sky (the pass runs whole-frame, so its base is read in the
bright end too).

Measured, 1160x774 at SHADOW +100, the high-frequency part of the gain field
(9px high-pass, where a real base can hold none): 0.0627 for the ring,
0.0048 for a blur of the same radius. Thirteen times. The fix is not more
taps — a 7x7 at a third of the step is still point samples, only smaller —
it is to stop sampling: the caller blurs.

So the base is now a second CHILD of the tone pass, the frame blurred by
Skia's own MakeBlur (blurredBase in exportEngine.ts, the draw drawBlurred
already made for the sharpening pass) at TONE_BASE_RADIUS of the frame width
and sigma TONE_BASE_SIGMA of that radius — a box's equivalent at the radius,
so the neighbourhood is the one the radius always named and the cuts are
smooth instead of hard. The shader reads it ONCE per pixel and baseLuma
loses its loop and its `bx`. That is also the cheaper pass: nine child evals
walked the exposure/matrix chain nine times, one eval does not.

A caller with no frame to blur hands in the image it is already shading as
the base. The tap then lands exactly on t and the ramp is the global move
again — a mask's degenerate bx of zero, spelled as a child that IS the
source, which is what gradientMask.ts's own call (base == t) already meant.

Checks: tone-base-check.mjs is new — SkSL is only compiled at runtime and
nothing here compiled TONE_SKSL whole, so the pass is compiled and rendered
for real, with the frame and the base held at two flat values a little
apart: the pixel has to land on the value the ramp over THAT base predicts
(171 for a 128 pixel over a 76 base), and a base equal to the pixel has to
be the identity. highlight-knee-check now pins the one tap, the absence of
`bx`, the blur, and the two-child wiring. 9/9 pass, build clean.

Skipped: no guided filter proper — the base is a plain blur, so a strong
edge is no longer held out of it the way the range weight held it (a dark
rock a blur's width from the water reads a lifted base and keeps its own
darkness). Add when a frame shows the halo; the doc asks for a plain blur
and this is one.

3dtours e61dccc784 light: the tone ramp is drawn through a base layer, not the pixel, so a SHADOW lift moves the region and leaves the texture in it standing — the quarter above the knot came back at 0.57x of its own spread, 0.78x now
The four knots were read at the pixel's own luma, which makes the ramp a
global curve: every pixel at luma t lands on the same o whatever surrounds
it. SHADOW's a1 is the head of the quarter above it, so lifting it squashed
that whole quarter to the half slope left over — measured on a real frame,
0.50 of its spread (shadow-band.py), 0.57 on the deployed bundle — the grey
sheet the knob was reported for. A curve drawn through the pixel cannot see
local contrast; that is what the eye was reading.

So the ramp is read at TONE_BASE_RADIUS (2.5% of the frame) of the luma
around the pixel — a 3x3 range-weighted blur, the fix_shadow.md Base x
Detail split — and the pixel then rides the neighbourhood's gain o/base,
keeping its own difference from it. Base moves, detail stays: the same lift
on the same pixels, with the texture inside the region left standing. Full
deflection keeps 0.78 of the band's spread now.

The base is the same maths in every caller: bx = 0 (a mask, which has no
neighbourhood) reads the pixel nine times and gets the old global move back,
and with every knob on zero the ramp at base IS base, so the ratio is 1 and
the pass is the identity however coarse the base is.

Skipped: no chroma compensation (Hunt). Measured, the ratio held saturation
(0.3184 -> 0.3169), so it is not earned yet. No linear-light ramp either:
the multiply is a uniform gain on encoded values, which is the same stop
exposureMove already argues for.

3dtours 25b1312e0a light: AUTO and the shipped recipes ride the halved knobs too — AUTO's ceiling doubles with them so a blown frame still comes back the way it did, and each recipe's HIGHLIGHT/SHADOW doubles so its look stays on the knot it was tuned to 2026-09-30 18:10:51 +07:00
3dtours a56581c757 light: the HIGHLIGHT knob rides half its anchor too, so a lift stops drawing a cloud to paper and a pull stops flattening the quarter under it — the top quarter came back at 0.26x of its own contrast, 0.62x now 2026-09-30 17:59:57 +07:00
3dtours 36fb93658b light: the SHADOW knob rides half its anchor, so a lift stops drawing the band above it flat — a waterfall's spray came back at 0.10 of its own contrast, 0.55 now 2026-09-30 17:36:29 +07:00
3dtours 3e3045d912 library: the reading is copied into a folder of the reader's own, so a cleared profile gets it back without a frame being read twice 2026-09-30 16:41:11 +07:00
3dtours 325d5c0470 library: the walk position belongs to the origin, so the app beside the browser carries a reading on instead of listing the roll again 2026-09-30 16:26:42 +07:00
3dtours 851563ed73 light: the pixel rides o/t, not a held chroma — SHADOW and BLACK drained a dark red to 0.505 of its saturation, it is 0.742 now 2026-09-30 16:26:42 +07:00
3dtours 2f34c36131 The room opens folded: the studio's panels and the catalogue's tree both start shut and come back the way they were left
Four asks, one shape: the LIGHT column had a chip that opened the same two
knobs DETAIL & EFFECTS already shows, the WB table was reading as one long
line per preset, the disclosure carets were too small to be the affordance
they are, and both folds — the studio's panels and the catalogue's folder tree
— opened fully every time. What the fold is for is the same in both places: a
column of a dozen controls is a wall to scroll past, and the control being
looked for is named by the head it sits under. So both open folded, and both
remember what was opened.

GRAIN's chip is gone from the LIGHT row. Its strip held a knob `grain` and the
"size" behind it, and both are rows of DETAIL & EFFECTS now — MONOCHROME GRAIN
and GRAIN SIZE — so the chip was a second way to one pair. The strip machinery
stays (`GroupKey 'grain'`, `groupDefs.grain`, `grainInch()`): it is reachable
from nothing today, and taking it out is a diff of its own. What went with the
chip is the `/INCH` readout, which only the strip drew.

The WB presets read as a name on one line and its kelvin under it: the label is
the chip's own label and the kelvin moved from the label into the value slot,
which the grid's rule stacks (`flex-direction: column`, `font-size: 11px`,
`white-space: nowrap`). Seven buttons, 147x39 each, name
box 14px — one line at 11px/1.25 — kelvin at 10px, `scrollWidth` equal to
`clientWidth` on every one of them. The kelvin rides a swatch, so it wears the
fill's own ink rather than the panel's dim grey (`.chip.tinted .val { color:
inherit }`): readableInk already picks #0b0e12 or #ffffff off that fill for
4.5:1, and dimming it a step costs contrast on a mid grey fill. Measured off
the running page: 4.88:1 (CLOUDY) to 5.00:1 (TUNGSTEN), name and kelvin alike.

The panels: `recipescam.develop.open` holds the slugs that are open, comma-
joined, and a slug no panel answers to is dropped on the way in, so a renamed
or removed panel leaves no hole. A visit that touches nothing writes nothing —
the column opens folded from an empty store — and a click on a head writes the
list as it stands. The caret is drawn a size up from the label it sits beside
(17px against an 11px head) and takes full opacity under the pointer, because
a line of uppercase does not read as a control on its own.

The tree: a row's click still opens it and folds it again, but the set it moves
in is inverted — what is *drawn open* rather than what is folded away — which
is what makes the state storable at all (a folded set is the whole tree minus
what is open, and the whole tree is not in that state to be stored). The
column opens with every folder shut, and the remembered set comes back over
it. A first visit under the new rule has no stored set and can still have a
folder remembered from before, so that one case seeds its ancestors: a screen
that opens on a node shrunk away behind a shut row is worse than a
remembered fold. COLLAPSE ALL folds the top-level row too now, which is what
makes it the way back to the column's rest — it was written when a top-level
row could not be folded, and the item is disabled when there is nothing open.
The caret is a leaf on a row with nothing under it, as it was.

`remember.ts` is the two functions both screens now share; Library had its own
copy of them.

The two checks that read these screens were wrong about the new fold and are
right about it now, not the other way round. `library-check` gains the rest
state (`the tree opens with the folders folded away — 1 rows`), walks the
tree a level per click, and reads the visit it left behind off a reload:
`lib-node-CheckRoll:true lib-node-CheckRoll/2026:true .../04:- .../Empty:-`,
with the screen marked on the subfolder. Two of its steps were stale
expectations rather than a fault: the fold-the-tree claim is one click over
four rows once the rows are opened for it, and the folder the screen reopens
on is the last row clicked, not the one clicked before it. `scan-nav-check`
asks the same tree for its deepest folder, so it opens the two rows above it
and folds them back — the reading it is watching does not move with rows.

Verified: `npx tsc --noEmit` clean, `npm run build` clean
(`dist/assets/index-T721P-Nv.js` 711.33 kB, `dist/assets/index-Co_dQD6t.css`
65.69 kB). `scripts/library-check.mjs` — "all checks passed", 55 steps, none
failing — including `the tree opens with the folders folded away — 1 rows,
aria-expanded=false`, `a row draws its own children, not the whole branch — 3
rows`, `and one click folds every row, leaving the frames where they were — 4
rows → 1, lib-node-CheckRoll:false, 2 tiles kept`, `the tree reopens with the
rows that were left open`, `the screen reopens on the folder it was left on —
lib-node-CheckRoll/2026`, `the screen reopens on the frame that was raised`,
and the column `198px, then 198px`. `scripts/scan-nav-check.mjs` — all steps
passed, its tree walk reading
`["lib-node-SlowRoll","lib-node-SlowRoll/2026","lib-node-SlowRoll/2026/04"]`.
In the running page: 5 panel heads and 0 panel bodies at rest with
`recipescam.develop.open` unset, caret `17px` `▸`; the WB table's seven rows
at 147x39 with name 14px one line, kelvin below at 10px, `nowrap`, no
overflow, ink 4.88–5.00:1; the LIGHT chip row `["auto","curve","fix",
"gradient-mask","mono","wb-temp:*","reset-all"]` — no `grp-grain` — with
MONOCHROME GRAIN and GRAIN SIZE still the two rows of DETAIL & EFFECTS; two
heads opened, `wb,effects` stored, and the same two open after a reload with
the other three shut. The deployed bundle was read too: `docker compose build
frontend && docker compose up -d frontend`, and `index-DpYWAhJ3.js` off
`127.0.0.1:8090` carries `recipescam.develop.open` and
`recipescam.library.open` and no `grp-grain`, with the same probe readings
taken against it.

3dtours cc186c4d09 The trial gets a date and WB's presets get a table
Two asks, one row of the studio each.

The first is copy: a band under the header, the same shape the verify bar below
it takes, saying which features are on trial, on whom, and until when. It is a
notice and not a task, so it wears the plain surface rather than the accent, and
it carries no dismiss: the date is the message. The string is in the dictionary
like every other, Vietnamese as written and English beside it — the band is one
line at both lengths in a 1440-wide window, and it sets no nowrap, so a narrow
window wraps it rather than cutting it.

The second is the WB panel's presets. They were a wrapping strip of seven
identical pills, which is the wrong shape for one kind of value read against the
others: nothing about "SHADE" said 7500K, and nothing about the row said which
end of the scale anything was on. They are a TABLE now — two columns of buttons,
laid out as a grid — and each button is painted with the cast it puts on the
frame: the same swatch the TEMPERATURE ruler already prints under its track
(temperatureSwatch, the engine's own gains on a mid grey, halved), so the button
and the ruler cannot disagree, and the kelvin is printed on the button beside the
name.

A button that is a swatch cannot use the theme's text colour for its label: the
fill is a mid grey by construction, and mid grey is exactly where white and the
light theme's near-black both sit near the 4.5:1 line. So the label is given the
ink that fill can carry, chosen by WCAG's relative luminance against black and
against white — whichever of the two ratios is larger, which is the one that
cannot fall under 4.5:1. The border is that same ink, which is what makes a
button stand out from the page it sits on and from the six beside it; the accent
takes the border over while the preset is the one in force, since the fill can no
longer say so. Both the fill and the ink ride in as inline styles — they are the
value, not the theme — so the chip needed two fields and a tinted class, and the
row needed a grid mode. The TEMP strip reads the same two fields through
choiceChips, because the same seven presets are painted in both places and two
opinions about 3200K is the bug this would have been.

The chip's own value slot is deliberately unused here: `.chip .val` sets its own
dim colour, and a dim grey on a mid grey button is the failure this commit is
about.

Verified: scripts/wb-table-check.mjs — readableInk picks the better of its two
inks for black, white and four mid greys, all 151 swatches across the ruler
(2500..10000K, every 50) and all seven presets clear 4.5:1 under the ink they are
given, the swatch runs the way the ruler does (red up, blue down, #517eff at
2500K to #947d61 at 10000K), and the seven presets collapse to the five fills
their kelvins do. In the running app through a probe: the notice prints in both
languages (Vietnamese one line, unclipped), 7 buttons in a 147px + 147px grid,
TUNGSTEN filled rgb(98,130,187) with ink rgb(11,14,18) and a 2px border of the
same, AUTO the accent border rgb(206,117,9) while it is the preset in force, and
the panel holds at 420px wide without overflowing. The panel was viewed in both
themes. npx tsc --noEmit clean, npm run build clean.

3dtours 6d60d452e0 One move of the light for the whole app: a mask's EXPOSURE and its four tone knobs stop being a second opinion
A gradient mask had its own tone formula and its own exposure, and both
disagreed with the frame's. Before any of this was tidied, the mask ran a
smoothstep luma lift with an arbitrary 0.55..1.35 chroma clamp while the frame
moved the knots of a four-zone ramp, and the mask's exposure was a stop on
sRGB-encoded values while the frame's was a stop on light. Two names, four
moves, and the same slider meant different things depending on whether the
pixels were inside the shape you drew — the divergence §3.3 of the Android
port's compat doc warns about.

The maths is one string now (TONE_MATH_SKSL, interpolated by both passes): the
ramp the four knots build, the hue-preserving rebuild behind it, the transfer
pair, and exposureMove. A mask calls the same functions the frame calls.

The rebuild carries the chroma instead of re-scaling it. Lightness takes the
curve and the colour rides the difference — the channel differences move by ONE
shared scale k, pulled back only where the cube has no room left. The doc's
ratio (R_new = R_old * Luma_new / Luma_old) was the old reading and it is exact
only while nothing clips: a channel past 1.0 stops being scaled with its
neighbours and the hue goes with it. Measured on a flat patch frame, a skin
tone at 24.0° came back at 48.0° at HIGHLIGHT +100, a warm white at 37° at
57.4°, and under L = 0.5 the same ratio multiplied a near-black pixel's cast by
x30 — colour noise amplified, which is why the 0.55..1.35 clamp was there. The
scale is the chroma's own now: over 135 knob combinations on seven colours and
five greys, the ramp moves the luma and the hue does not move at all (Δ < 1e-9°).

EXPOSURE gets the same treatment, which is what the second half of the request
was: the linear domain decides where the luma is going, and the pixel is
rebuilt onto it through the same lightMove. The old pass multiplied the three
channels in linear light, so +1 EV clipped them by three different amounts:
measured on the scratchpad probe, 29.2° of hue drift on a skin tone at +1 EV
and 33.3° at +2, against 0.00° here. The stop is applied as a ratio on the
pixel's own encoded luma rather than pointed straight at the encoded linear
target, which is what makes the knob exactly the identity at 0 EV — the
transfer does not commute with the luma weights, so pointing at it brightened a
colour by a couple of code values even at zero. A grey is the knob it always
was: 128 through +1 EV is 176, the same number the linear per-channel multiply
put there, so nothing a user has dialled in moves.

Verified: `npx tsc --noEmit` clean, `npm run build` clean. highlight-knee-check
now runs EXPOSURE_SKSL for real — compiled with CanvasKit and four pixels
pushed through it, agreeing with the twin to a code value on a grey at +1 EV
(176), a skin tone at +1 EV and +2 EV, and a shadow at -2 EV; it also pins the
hue, the cube, the identity at 0 EV and the black pixel that has no light to
move. mask-wb-check compiles the mask pass and pushes the same stops through
it: 128 through +1 EV is 176, through -1 EV is 92, +2 EV lands the channel on
the ceiling at 255 and holds the hue within 3°. auto-tone-check,
preview-match-check, white-level-check, raw-develop-check, half-check and
roll-walk-check all pass. Live on the built bundle in a 1440x950 browser: the
LIGHT panel's EXPOSURE +1 EV takes the mid grey of a flat patch frame from
0.502 to 0.690 (a stop on light gives 0.686) and moves no patch's hue at -1 EV
(Δ 0.00°), and a linear gradient mask's EXPOSURE +1 EV and HIGHLIGHT +100 move
the pixels inside the mask (luma 185.9 -> 211.1 and 185.9 -> 197.5) while the
corner outside it does not move at all (220.2 -> 220.2), with no console error.

3dtours 3b92e4e2d2 A gradient mask can carry the LIGHT column's white balance now: COLOR TEMP and
TINT, the same two rulers, read on the mask's own pixels.

The pair was asked for as the two rows the develop column already has, so it is
the same pair and not a second opinion about what a kelvin means: the gain comes
from one function, colorUtils.whiteBalanceGain(temperature, tint), which the
frame-wide colour matrix now calls too — the RGB kelvin fit of kelvinToRGB, the
symmetric ±0.08 magenta/green tint, and the division by the product's own Rec.709
luma that keeps a cast from being a brightness move. A mask that never touched
the pair reads 5500K / 0 (readMasks' own defaults, clamped to the ruler's ends),
whose gain is exactly (1,1,1), so nothing moves and every recipe stored before
this reads the same. The measured rule holds inside a mask exactly as it does on
the whole frame: at 10000K the mask's pixels came out R/B 1.25 -> 1.72 against
0.994 -> 0.994 outside it.

The Kelvin fit is a curve, so it is resolved on the JS side and handed over as a
gain: maskUniforms grows one more float4 array (wb[i], three gains and a zero
pad) between the spatial pair and the frame size, in declaration order like every
other array in that buffer, and the shader multiplies the mask's colour by it
right after EXPOSURE — one clamp, three multiplies by one for a mask that leaves
the pair alone, and no second copy of the fit in SkSL. The spatial build is a
second shader text with a second signature and reads the same array.

App.tsx draws the rows where the panel's other rows already are, and TINT rides
the existing maskKnobRow helper: same store unit (±10), same ±100 slider the
frame-wide row wears since the develop knobs were deepened. COLOR TEMP keeps its
own scale (2500..10000, step 100, "10000K"), because a temperature is not a
percentage, and it carries the same swatch the frame-wide row paints.

Verified: npx tsc --noEmit; npm run build; the repo's check set (highlight-knee,
auto-tone, half, white-level, preview-match, library, scan-nav, roll-walk) all
pass; and scripts/mask-wb-check.mjs, which is new here — it transpiles the
gradientMask graph into a temp dir and checks the gain (neutral at 5500K/0, warm
at 10000K, cool at 2500K, luma-preserving, ±TINT symmetric), the clamps, the
uniform offsets (the gain lands where the shader reads wb[i], the frame size one
array further on), and then compiles the real shader through CanvasKit and pushes
a mid-grey through it: neutral leaves 128, 10000K warms it, +TINT magenta-ises it,
and both the plain and the spatial builds and a two-mask list read it. The UI was
driven on the built bundle too (a linear mask dragged on the preview, then the
two rulers moved through their own range inputs): the mask column reports 11 rows,
opens at 5500K / 0, takes 10000K and +40 ±100-scale TINT, the swatch follows, and
the preview's own pixels warm inside the mask and nowhere else.

ponytail: the mask's WB is not skipped for monochrome stocks the way the
frame-wide matrix skips it — a local kelvin on a B&W frame is a tint someone
asked for by hand, not the colour leak that rule exists to stop. Add the same
isMonochromeBase guard (and pass the base filter into maskUniforms) only if that
turn out to read wrong on a live B&W recipe.

3dtours c0aaa67361 Studio: fold WB and FX into LIGHT, and put every develop slider on -100..+100
WB and FX were separate tabs whose only content was the same Lightroom-style
develop column LIGHT already renders, so the rail carried three doors into one
room. LIGHT now owns the whole column: white balance, tone, presence, the
effects group (grain, dehaze, vignette) and the filters, in that order. The
`wb` and `fx` TabIds, their rail entries, their `wbLabel()` helper and the now
dead `tab.wb` / `tab.fx` i18n keys are gone; `ToolRail` documents eight tabs.

Every continuous develop value that the UI exposes as a symmetric knob now
runs -100..+100 instead of -10..+10. `paramDefs` gains the `HUNDRED` key set
and the `deepen` helper, which widens a def's range and scales its accessors by
ten, so the store keeps its -10..+10 internal scale and every stored look,
DEFAULT_RECIPES entry and URL round-trip is byte-identical. Params with a
meaningful physical scale (temperature in kelvin, exposure in EV-ish units,
grain, grain size, hdf, vignette, rotate, crop) keep their own units.

Highlight recovery no longer bends hue. The old knee clamped the per-channel
gain into 0.55..1.35, which is a per-channel operation and therefore a hue
rotation: on the flat skin patch it walked hue from 24 deg to 48 deg at
HIGHLIGHT +100, and on a saturated 30:1 chroma ramp it desaturated toward black
instead of toward white. The shader now caps the pixel's distance from its
undersaturated knee point while preserving the direction of that offset, i.e.
it scales chroma and keeps hue, then clamps into gamut.

Verified:
- `npx tsc --noEmit` clean; `npm run build` clean.
- `node scripts/highlight-knee-check.mjs` (pins the new shader source and
  twin-tests 135 knob combinations) ok.
- Existing checks re-run green: `auto-tone-check`, `half-check`,
  `white-level-check`, `preview-match-check`, `library-check`,
  `scan-nav-check`, `roll-walk-check`.
- Live browser pass: rail shows exactly the seven expected tabs with no WB or
  FX; LIGHT renders 5 panels / 23 `data-key` knobs; 12 knobs report
  `min=-100 max=100`; everything else keeps its own range.
- Highlight hue measured on ten flat colour patches: HIGHLIGHT -100 gives a
  hue delta of 0.00 deg on every chromatic patch; HIGHLIGHT +100 stays within
  0.22 deg (sky) and 0.28 deg (magenta) wherever chroma survives, and the
  patches the ramp intentionally drives to white arrive fully neutral. Greys
  stay neutral (channel spread <= 2/255) at every knob setting. Skin patch
  before/after: 23.94 deg -> 0.00 deg.

ponytail: temperature (2500-10000 K), exposure (+-10 units at 0.25 EV each),
grain, grain size, hdf, vignette, rotate and crop deliberately keep their own
scales rather than the blanket -100..+100; widen them the day a user asks for
more range, not before. Hue assertions live in the flat-patch check because
real-photo measurements pick up 2-4 deg of resample drift from the snapshot
pipeline that has nothing to do with the shader.

3dtours 34f8601c91 studio: the develop column becomes five panels, and the four tone knobs move knots instead of channels
Two specs, one commit: the develop state becomes the panel column the Lightroom
spec draws, and HIGHLIGHT, SHADOW, WHITE and BLACK stop being edits and become
shapes of the tone curve, the way the mapping spec measures them.

The column. The left rail used to hand LIGHT a row of chips and nothing else;
the four tone knobs were chips that opened a curve, and the rest of the develop
state lived in the chip row's own vocabulary. `DevelopPanels` renders the five
sections of the spec instead — PROFILE, WB, TONE, PRESENCE, DETAIL & EFFECTS —
as an accordion, all open, and every parameter the recipe holds has a row in it
with a `data-key` off the parameter name: slider, value readout, double-click to
default. Sliders are always visible, so a knob is one drag away instead of two
taps, and TEMPERATURE and TINT draw their gradient underneath (blue through amber,
green through pink) so the direction is on the control. The PRO looks the spec
marks stay in the list but locked, tagged PRO, and tapping one asks for PRO —
they are shown, not hidden, and not silently dropped.

WHITE and BLACK move out of the WB group. They were the temperature group's
extremes, which is what a white balance control does — the toe and the shoulder
of the same ramp — but the spec puts them with the tone knobs and gives them the
two ends of the tone curve, and that is what they now are. `wb` is TEMPERATURE
and TINT and nothing else; `whites` and `blacks` sit in `iq` beside `highlights`
and `shadows`, labelled WHITE and BLACK, in the tone panel where the slider lives.
A recipe written before this commit still reads: the keys are unchanged.

The four knobs. The first pass of the mapping spec added a mask per zone onto the
channel: `luma += knob * mask * intensity`, and the shader followed it. It is the
wrong shape, and the twin harness in `highlight-knee-check.mjs` shows why — the
four masks are not a partition of the ramp. They sum to one at the ends and to
zero at the midpoint, so an adjustment in the middle of a zone is applied where
the mask is half and not at all where the mask has fallen to nothing, and the
ramp inverts: with every knob at its stop the curve folds over itself, slope −5
at t=0.87, and the twin catches it as a non-monotone ramp.

So each knob moves a knot on the curve instead, which is the reading the spec's
own mask geometry points at — BLACK peak at 0.00, SHADOW 0.00→0.25→0.50,
HIGHLIGHT 0.50→0.75→1.00, WHITE peak at 1.00 — and the shader builds the curve
through those four anchors. `TONE_ANCHOR` is 0.25: one full knob at its stop is a
quarter of the range at that knot, so the range is 0.75..1.00 at the top and
0.00..0.25 at the bottom, and the anchors stay ordered (`a0 ≤ a1 ≤ 0.5 ≤ a3 ≤ a4`)
by clamping each against its neighbour. Between knots the curve is a straight
line, and 0.5 is untouched by every knob, so a knob at zero is the identity
exactly rather than nearly, and any combination of the four is monotone. The mask
sum survives where the spec is right about it: it hints the split between the two
dark zones and the two light ones, nothing else.

The hue is kept the way the spec keeps it: work in luma, then scale the chroma
offset — `rgb = luma_new + (rgb - luma_old) * luma_new / luma_old` — so a
saturated red stays the same red and only its brightness moves. The ratio is
clamped to 0.55..1.35 because at luma near zero the division is the whole
highlight of the picture on one code value.

Verified:

- `node scripts/highlight-knee-check.mjs` passes. It pins the settled shader —
  four masks, four anchors, the four `mix` lines — and asserts the constructions
  it replaced are gone, then drives a twin of the ramp in JS: the masks do not
  overlap, every knob at zero is the identity, the midpoint is 0.5 for all 162
  combinations of the four knobs, every combination is monotone, the amplitude at
  each stop is a quarter, and the DR offsets land on 0.12 and 0.82. The folded
  case from the additive build is in the harness as a regression.
- `npx tsc --noEmit` clean; `npm run build` emits `index-DXIIw2F1.js` and
  `index-A4pA1U5f.css`; `library-check.mjs`, `scan-nav-check.mjs`,
  `roll-walk-check.mjs`, `auto-tone-check`, `half-check`, `preview-match-check`
  and `white-level-check` all pass against the bundle — the catalogue, the RAW
  path, auto tone and the white level are untouched by the panel move.
- Driven in a real browser (`tone-live-check.mjs`, Chromium against
  `vite preview`, a P1010256.JPG in the source control, mean luma of the preview
  canvas read before and after each knob): neutral 184.25, WHITE +1 187.35,
  BLACK +1 186.35, SHADOW +1 194.53, EXPOSURE +1 206.99, HIGHLIGHT −1 173.80.
  Every knob moves the picture the way the spec says it should and none of them
  moves it much — a stop of a knob is a quarter of a zone, not a level.
- The same run asserts the built DOM: five panels, the 23 `data-key` rows,
  `dev-temperature` in WB, `dev-whites`, `dev-blacks`, `dev-highlight` and
  `dev-shadow` together in TONE, the gradient classes on the two white balance
  sliders, and the chip slots the panel is handed. The only failed request is
  `/api/events`, which is the backend this preview does not run.

ponytail: the recovery of blown highlights that used to sit under HIGHLIGHT — a
per-channel rolloff in linear light — is gone, deleted rather than ported. The
additive mask is why it was there: HIGHLIGHT had to do two jobs because a mask
could not shape a curve. Now that WHITE owns the top end, HIGHLIGHT only bends,
and the per-channel rolloff is a second knob for the same picture. Bring it back
as its own parameter if a frame ever clips badly enough to need it.

Also dropped: DR used to ride along as two additive terms. That is where the fold
at t=0.238 came from, BLACK −1 and SHADOW −1 together — the two terms pushed the
ramp past its own end. It shifts the knots now, which is what the film sims
always meant by it, and the numbers in the sims were kept and their meaning
recommented (classic-chrome toe 0.22, head 0.7375, etc.).

3dtours 426488a788 studio: say the roll is still being read while the catalogue is off screen
The reading of a folder belongs to the tab, not to the catalogue screen: it was
made to survive the hand-over to the studio in 753eea0, and it does. What was
missing was any sign of it up there — a visitor who hands a half-read roll to the
studio saw a page that said nothing about the frames still landing, and had no
way to tell a reading in flight from one that had quietly died. The one thing
that did say so, the toolbar line, lived on the screen they had just left.

The header now carries it, immediately left of the way back into the catalogue,
where the two belong together: the ring the catalogue already uses for a roll in
hand, and the count the toolbar states, "4/12", whose title is the same
"Scanning 4/12 — 0 new…" line in the visitor's language. It reads the session
through scanSession() and watches it with watchScan() exactly as the catalogue
does, so a pass that moves the progress moves the header too — the session object
outlives them both, only its progress is replaced each pass. No new state is
introduced, no new copy: the markup borrows .lib-spin and the lib.scanning key
the catalogue already had.

Verified: tsc --noEmit and vite build clean; scripts/scan-nav-check.mjs grew one
step at the first hand-over, "the studio header shows the reading the tab is
doing", which waits for [data-key="studio-scan-count"] mid-scan and matches it
against \d+/\d+ — it passes with 4/12, the same reading the toolbar shows at that
moment; the other 18 steps of that check, the 52 steps of library-check.mjs and
roll-walk-check.mjs all still pass.

ponytail: the header states progress, it does not offer to stop the scan; the
catalogue's own STOP stays the one place that ends a reading. Add a control here
when someone asks to stop a roll from the studio.

3dtours 53cb1c97e9 web: a frame is scored under the picture, and the wall is read through the score
The catalogue could say what a frame was and when it was shot, and nothing about
whether it was any good. A reader who had been through a roll of two thousand
had no way to say "these four", and the thumbnail wall drew every frame the open
folder held in the one order it had: newest shutter first, always.

The frame that is up now carries its own score — five stars under the picture,
and the star the click lands on is the score it gets. The star it already has
takes the score back, so a score that was given by mistake is taken off without
a sixth control. It is the catalogue's own row and nothing on the disk is
touched: the file is not written and not read, the browser only stores one more
number against a frame it already holds, and the number is the reader's.

The wall is read through three of them. The score is the first — four stars and
up is the floor, any rating is the wall as it was — because that is what a
reader who has just been through a roll wants next. The year the shutter fired
in is the second, offered as the years the open folder actually holds and not a
century of empty ones. The hours it fired in are the third, as a from and a to:
16:00 to 18:00 is the afternoon the reader was out, and either end alone is
"from 16:00" or "up to 18:00". All three read the shutter time, on this
machine's own clock — the same reading the frame's date line prints, so the
afternoon is the afternoon and not an offset of it. Beside them, the order: the
newest shutter first, the oldest first, or the most stars first.

What the filters hold is the wall and only the wall. The strip under the picture
is the shelf the open folder is, and a shelf that quietly loses three quarters
of its frames is not a shelf any more; the frame that is up has to stay reachable
while the wall is narrowed around it. That is also why the filters are drawn in
the thumbnail view: they are a way of looking through the shelf, not a property
of the roll, and nothing about them outlives the visit.

Verified:
  library-check.mjs — 52 steps, all passed, five of them new. The frame that is
    up is scored from the row under it and the catalogue holds star 4 against it
    (aria-pressed on the fourth star true); the wall narrows to one tile at 4★,
    to none at 5★, and back to three with the rating cleared; the year 2016 holds
    the two JPEGs of three and 16:00–18:00 the same two, out of a roll whose
    frames are written years apart in different parts of the day (the JPEG in the
    afternoon of 15 Feb 2016, the RAW at seven in the morning of 1 Jan 2026);
    read by score, the scored frame comes first. Every earlier step still holds,
    including the two that count what a reading costs and the stand-in folder's
    two frames — the JPEG carrying the GPS tag and the RAW printing
    "26.4mm · f/2.8 · 1/320s".
  scan-nav-check.mjs, roll-walk-check.mjs — all passed. frontend tsc --noEmit
    clean, vite build clean.

ponytail: the score is one number on the frame's own row — no rating table, no
votes, no accounts; the catalogue is a per-browser shelf and so is the score. The
filters live in the thumbnail view's own state, so a reload starts with the whole
shelf again, which is what a filter is for. No text search: a roll of date folders
is three levels deep at most, and the three that a reader actually digs with are
the ones here — add the box when a folder of mixed names makes one worth typing
into.

3dtours 477c71d1f4 web: the frame under the preview says where it was shot and what it was shot with
A negative is opened to be looked at, and the two things a photographer reads
off it first are the numbers the camera wrote and where it stood when it wrote
them. The stage gave the name, the folder, the date and the weight of the file,
which is what the catalogue knows; the rest was a trip into the studio.

Both are now under the picture. The numbers are the camera's own — ISO, focal
length, aperture, shutter, frame size — printed in the order a photographer
says them, and every one the file does not carry is left out rather than stood
in for: a Fuji RAF gets no line at all, a Panasonic RW2 gets the glass and the
shutter and no ISO, and a JPEG gets the lot. Where the frame was shot is the
GPS it carries, named by the geocoder when one answers and left as the
coordinates it holds when none does — a naming is a network round trip on a PRO
account, and the numbers do not wait for it, so a refusal or a miss costs the
reader nothing.

What this costs is one read of the frame's first few hundred kilobytes, the
same head a scan hands the parser, and only the frame that is up pays it: the
strip walks past a hundred negatives without reading one of them. The read is
held by the read itself and not by the frame object under it, because the
catalogue is read back on a timer while a scan runs, which hands the screen a
fresh object every few hundred milliseconds — a screen that went by the object
would read the same file again and again for as long as the scan lasts.

The check's stand-in folder had no frame of its own with a GPS tag on it, and
none of the samples carries one, so the check writes one: an APP1 segment
holding a GPS IFD and nothing else, spliced in right after the frame's SOI. It
is deliberately the first APP1 — a JPEG carries one EXIF segment and the
catalogue reads the first, so a file that has a place is a file that spent its
EXIF on the coordinates. That is also what makes the RAW the frame that shows a
spec line, and the two frames now check the two halves of the same feature.

The run counts what a reading costs, and a head is not what it counted before:
it counts the whole file a lane develops apart from the head a parser is handed,
because "the RAW was read" is a claim about the scan and the preview legitimately
reads the same file's head.

Verified:
  library-check.mjs — 47 steps, all passed, two of them new. The JPEG off the
    check's server carries a GPS tag and the page keeps 16.0544, 108.2022 under
    the frame, with no geocoder behind it to name them; the RAW prints
    "26.4mm · f/2.8 · 1/320s" — the glass and the shutter it has, no ISO and no
    frame size it does not. Every earlier step still holds, including the one
    that says a scan does not read a RAW whose size and write time have not
    moved: whole reads {}, heads {"P1010256.RW2":1,"P1010256.JPG":2}, the one
    RAW head being the frame that is up.
  scan-nav-check.mjs, roll-walk-check.mjs — all passed. frontend tsc --noEmit
    clean, vite build clean.

ponytail: the place is named by the API's geocoder and nothing else — no map, no
picker, no place a reader can type. The coordinates are what the file carries,
and a file that carries none shows no line, which is the honest answer and the
common case for a phone frame with location off. The line is read for the raised
frame only; a grid of hundreds is a list of names, and a row of ISO numbers
under each tile is not what it is for.

3dtours 753eea0d7b web: a reload in the middle of a reading goes on, it does not start over
The reader opens a roll of a few thousand frames and holds Ctrl+Shift+R while
it is being read — over a reading that takes minutes, that is the one thing
they do. What came back was a reading that started again at the top: every
folder listed a second time, the toolbar counter back at zero, the frames that
were already in the catalogue walked over so that their size and their write
time could say they had not moved.

None of that was in the catalogue, because the catalogue only holds the frames
that were read. What was lost with the page was the reading's position: the
folders the walk had been through, the folders still in its queue, and the
frames it had found and not yet read. The catalogue alone can never answer
where a reading was.

The position is now written to session storage as the reading goes — walked,
pending and the frames in hand — and read back on the way in. Session storage
and not local storage, because a position belongs to the tab: the tab that
reloads carries on from the frame it stopped at, and a tab opened beside it
starts a reading of its own. The key goes when the reading finishes, and goes
with the folder when the folder is removed.

The frames in hand are the part worth spelling out. A frame a lane is in the
middle of, and a frame whose row is in the batch and not yet in the catalogue,
are on neither side of the line the position is written on: the catalogue does
not hold them and the walk will not find them again, so both are written into
the queue and read again. They also were counted when they left the queue, and
the count is written with them — else the reloaded reading would count them a
second time. The counter now carries on from where it was instead of restarting
from zero.

One thing was hidden behind the other: the stand-in folder the check hands the
page had no `getFileHandle` and no `getDirectoryHandle`, so the path that asks
the root for the frames a position names threw and answered nothing — and the
reading then walked the roll from the top, exactly the behaviour the check was
meant to catch. The check's folder answers both now, the way the browser's does.

Verified:
  library-check.mjs — 45 steps, all passed, two of them new. The reading is
    stopped on the frame it is reading (`check.hold`), the tab is reloaded, and
    it comes back at "Scanning 3/3 — 0 new…" — the same line it was stopped at,
    not a reading starting over — with the position still holding 4 folders
    walked, an empty queue and 3 frames in hand. Listing 3 tiles and letting the
    key go, the reading finishes the roll: 3 tiles in the strip, the catalogue
    written, the position cleared, and every folder listed once
    ({"2026":1,"CheckRoll":1,"Empty":1,"04":1}) where a reading that started
    over lists each of them twice.
  scan-nav-check.mjs, roll-walk-check.mjs — all passed. frontend tsc --noEmit
    clean, vite build clean.

ponytail: the position is the tab's, so a reload keeps it and a new tab does
not — the tab that reloaded is the one the reader is looking at, and a second
tab reading the same roll from the top costs a walk and no bytes, because a
frame that has not moved is dropped on its size and its time. The position is
written at the batch beat, so a reload reads at most one batch again, and the
frames in hand are read again on purpose: their rows were never stored.

3dtours d7241531f9 web: a reading walks past the recycle bin, not into it
The walk already turned its back on the folders a camera and an editor leave
behind: a name beginning with `.` or `@` is skipped, which is `.thumbnails`,
`.git`, `.Trash`, and the `@eaDir` a Synology writes beside every frame.

An external volume drags along a second set of names, and none of them begins
with a dot, so every one of them was walked. `$RECYCLE.BIN` and `RECYCLER` are
where Windows parks what the reader deleted — frames among them, at full size,
and every one of them decoded into a thumbnail on the way in. `System Volume
Information` is Windows' own bookkeeping. `#recycle` is the Synology share, and
`lost+found` is the directory a Linux volume keeps for repairs. A frame that
comes back out of a bin is a frame the reader threw away, and the pictures in a
share's recycle folder are pictures someone else deleted; neither belongs in
the catalogue, and both cost the reading the same seconds a real frame does.
The folder also stood in the column as a row of its own.

The rule is now one `SYSTEM_DIR` expression over both sets, matched
case-insensitively — the same volume spells the bin `$RECYCLE.BIN` on one drive
and `$Recycle.Bin` on the next — and the walk asks it before it looks at what
the entry is, so a refused folder is neither read nor named.

Verified:
  roll-walk-check.mjs — all passed, with two new assertions: the stand-in roll
    now carries `$RECYCLE.BIN`, `$Recycle.Bin`, `RECYCLER`, `System Volume
    Information`, `#recycle` and `lost+found`, and every one of them holds a
    file named like a frame, so nothing about the files can be what keeps them
    out. No frame is read from them, and none of them reaches the column.
  library-check.mjs — 43 steps, all passed. scan-nav-check.mjs — all passed.
    frontend tsc --noEmit clean.

ponytail: the list is the names the volumes being read actually use, not a
guess at every spelling there is — a box that files its junk under something
else gets a line in that expression, which is the whole of the change. A folder
of the reader's own that happens to be called `#recycle` is skipped too; that
name is worth the trade.

3dtours fbe9a1bb5b web: a roll is read where it was left, and only for the frames that moved
A reader with a large roll ran into three things at once, and they were one
thing: a reading is dropped the moment the tab goes, and the second one over
the same folder took as long as the first.

The catalogue was never emptied — `scanFolder` has no delete anywhere in it —
but it read every frame again. The test that was meant to skip a frame that has
not moved compared the frame's *shutter* time with the file's write time
(`seen.taken === file.lastModified`), two numbers that are equal only by
accident: a still's EXIF date is when the picture was taken, not when the file
was written. So a rescan of any indexed roll went back to the disk for every
file, decoded every frame and wrote it back — which is what reads as "it threw
the index away and started over", and it cost the same minutes the first read
did. A frame that cannot say when it was taken was worse off: it falls back to
the file's own time, so it matched, was skipped forever, and never picked up an
edit.

A row now carries `mtime`, the write time the browser reports for the file, and
a frame is skipped on the same size and the same write time — which is what the
comment over that line always claimed. A row filed before the field existed has
no `mtime` and is read one last time. On the 36-frame roll the bench serves (24
JPEG 8.2MB + 12 RAW 22.6MB, two levels deep):

  first reading        5209ms
  the same roll again  2887ms   24/36 frames read again
  first reading        5320ms
  the same roll again   603ms    0/36 frames read again

And the screen starts that reading itself. Opening LIBRARY on a roll whose
reading ended when the app did now walks it again on the way in — and again
when the tab is raised — so the frames it never got to are read with no one
asking, and frames that landed in the folder since are picked up by the same
walk. The scan belongs to the tab and the walk skips what the catalogue already
holds, so a frame that has not moved is a name, a size and a time and nothing
else; the run that does it says nothing in the toolbar, the ring on the row and
the progress line are the report.

The folder menu's commands lead with a mark of their own — fold ▴, rename ✎,
scan ↻, forget ✕, reconnect ⚿, add + — the way the tool rail and the view
switch already do: a column of marks reads at a glance where a block of
uppercase does not.

Verified:
  library-check.mjs — 43 steps, all passed, six of them new: the folder menu's
    three marks, the row menu's four, the add-only menu's one, the refused
    folder's lone reconnect carrying its ⚿, a reading cut short that goes on by
    itself (three rows back, and the bytes read are the two frames the
    catalogue had lost, not the one it still held), and the folder read again
    from its own menu. The stand-in folder now carries `__fake` on both handle
    kinds — a folder handle that does not is one the screen cannot ask about
    after a reload, which is a folder it offers to reconnect — and the frames
    it hands out report one write time instead of `Date.now()` per call, which
    is what a real handle does and what a frame is skipped on.
  scan-nav-check.mjs — all passed, the row still counting the reading as it
    comes rather than the catalogue standing still. roll-walk-check.mjs — all
    passed. frontend tsc --noEmit clean.

ponytail: nothing watches the folder, so a roll that changes under a screen
left open is picked up on the next visit or the next raise, not on the change —
a FileSystemObserver when the browsers ship one. A frame is skipped on size and
time alone, so an edit that keeps both is invisible until that frame is read
again; the row's own rescan is the way to ask for exactly that.

3dtours 36cd711302 web: the header wears the theme, and the rail says which build it is
Two things the studio could not say about itself.

The preset the header has open was painted in the dim text colour, the same grey
as the page name beside it — so the one label up there that changes with the look
read as chrome. It now takes the theme's own accent, the colour the brand mark
and the open tab already carry, which means it follows both the light/dark mode
and the accent group the reader picked, out of the CSS token and with no colour
written into the component.

And an image has no other mark on it: once the frontend tarball is loaded on the
NAS as `:latest`, nothing on the box says which revision came off. The rail now
names the build at its foot — quiet, mono, wrapping rather than widening the
column, and gone under 860px where the rail is the phone's scrolling tab bar
instead of a column.

The name is stamped into the bundle at build time: vite.config reads VERSION
from the environment (`docker compose build frontend --build-arg
VERSION=$(git rev-parse --short HEAD)`) and falls back to the package version
plus the minute it was built, so two builds of the same tree are never the same
name. `ARG VERSION=` in the Dockerfile is the knob; the bare `npm run build` —
dev server, check scripts — still stamps its own time, and the dev server passes
nothing at all, so the line only draws when there is something to say.

Verified:
  library-check.mjs — 37 steps, all passed, the two new ones reading the header
    off the running studio: the rail foot names the build (0.1.0+202609281504)
    and the preset chip's computed colour is the brand's accent, not a grey —
    rgb(206, 117, 9) amber, rgb(93, 24, 191) after switching to violet.
  scan-nav-check.mjs and roll-walk-check.mjs — all passed. frontend tsc --noEmit
    clean. Live 8090 on index-… matching dist/: /, /library and /app 200 with 0
    console errors.

ponytail: the name is the package version plus a caller-supplied tag, and nothing
bumps the package version, so the tag is the whole identity — have the release
job write it into package.json if the numbers ever need to mean something.

3dtours 134489a5ec web: come back to the frame that was raised, and zoom it by the wheel
Two things the preview owed a reader.

The frame raised in the strip outlived nothing: leaving for the studio and
coming back dropped the choice and the node opened on its first negative
instead. It is now remembered beside the folder and the column width — the
same one-line store, read on the way in, written on the way out — and a
frame that is gone from the catalogue falls through to the first, the way
a node that is gone falls back to its folder.

A wheel over the frame now magnifies it. The listener goes on the element
rather than through onWheel, because React's own wheel is passive and this
one has to hold the page still while it zooms; the origin is the point
under the pointer, which is what keeps a reader's aim on the thing being
looked at, and the step comes from how far the wheel turned so a notched
mouse and a trackpad travel the same. Six times is where it stops — the
thumbnail behind the preview has no more pixels to give — and a frame that
has just come up is fitted again.

library-check: 35 steps, the two new ones raising a nested frame, reloading
on it, and ticking the wheel up and back down.

3dtours 067b32131e web: drop the heading over the folder column
The column carried the name of the folder its tree belongs to, painted
above the rows. The rows already say it — the head of the tree is a row
like any other — so the heading only said it twice, and because it was
not a row it stayed on screen when the tree was folded away: the one
label left with nothing under it. The right click that raised it now
finds the row itself, which is where a reader aims anyway.

The label, its menu hook, its translation and its rule go; the tree, the
row menus and fold-all keep working as before.

3dtours 5e28b42067 web: fold all keeps the top-level row open
COLLAPSE ALL folded the top-level row as well, and that row is already its own
fold: one click on its name shuts it and takes the whole subtree with it. Folding
it from the menu hid every row of the tree — the item repeated a click the reader
already had, while the one thing a click there cannot reach, the folders nested
below, was the part that got lost with it.

So the item folds the folders nested below the top level: every row with a
subfolder under it that is not itself a folder picked at the top level. The
top-level row stays drawn and stays open, its own subfolders are drawn folded,
and no top-level row ever leaves the column. `nested` is computed off `parents`
once, and the item is disabled on a folder with nothing nested under it.

Verified:
  library-check.mjs — 35 steps, all passed. The fold step now reads the rows the
    click leaves behind instead of a row count: the fully open roll (4 rows)
    becomes exactly CheckRoll aria-expanded=true, CheckRoll/2026
    aria-expanded=false, CheckRoll/Empty (a leaf, so no aria-expanded) —
    CheckRoll/2026/04 is away, the top-level row is not — with the strip's 2
    tiles unmoved and the row menu still leading with lib-menu-collapse.

ponytail: with several folders picked, one COLLAPSE ALL folds the nested rows of
all of them, not only the row that was clicked — no top-level row is hidden
either way; scope it to the clicked folder's prefix when a column routinely
holds many picked folders.
2026-09-28 21:23:56 +07:00
3dtours 4a740b1e28 web: fold the tree from the row a reader right-clicks
COLLAPSE ALL lived only on the column's own name — the label above the tree —
and that label scrolls with the list it heads: on a roll read deep the column is
scrolled past it, so the item looked like it only appeared once the top-level row
had been folded to bring the list back to the top. The row is where the pointer
already is, and it already carries the folder's menu.

The top-level folder row now leads its own menu with COLLAPSE ALL — rename,
rescan and remove follow it, and a subfolder row is unchanged, since folding a
whole tree is what a row that a tree hangs from can do and a row inside one
cannot. Both entry points run the same one: `root` on the menu state now means
"the head of a tree", the column's own name or the row of a folder picked at the
top level, and the menu draws the item first and then whatever the subject
itself has — the folder's items, or, on the empty part of the column, ADD
FOLDER. The empty part keeps ADD FOLDER alone: it is not the head of a tree.

Verified:
  library-check.mjs — 35 steps, all passed. The new step right-clicks
    lib-node-CheckRoll with the tree fully open (4 rows) and gets back exactly
    [lib-menu-collapse, lib-rename-CheckRoll, lib-rescan-CheckRoll,
    lib-drop-CheckRoll]; a right click on the column's name still answers with
    lib-menu-collapse alone; the subfolder menu above is still the three folder
    items with no fold in it; the empty column still offers lib-menu-add alone.
    The fold itself is unchanged and still measured by opening the root back up:
    4 rows → 1, and 3 back, with CheckRoll/2026/04 still away.

3dtours c1ee2cf30a web: fold the whole roll from the head of the tree
A roll read to the bottom of its dates is a long column of indented rows, and
the only way to shut it was one row at a time — the click that folds a row also
opens it, which is the right trade for reading and a poor one for putting away.
The column's own name is now the whole tree's control: a right click there opens
a menu whose one item is COLLAPSE ALL / THU GỌN TẤT CẢ, and it folds every row
that has something under it at once — the root's own row included, so the tree
comes back to one line per picked folder and the subfolder two deep is away with
the rest. The menu is the folder menu's shape at a third subject rather than a
second menu: one `root` flag on the state that already knows where a right click
landed, and the same Escape, same click-away, same clamp to the window edge.

The frames do not move with the rows: folding is a way of looking at the tree,
and the strip already reads the open folder, which the fold leaves alone. The
name keeps reading as the folder it belongs to — the folder's label, with the
hint appended to its title — and the item is disabled rather than hidden when
nothing in the column has children, so a fresh folder does not open a menu with
a dead line in it.

Verified:
  library-check.mjs — 34 steps, all passed, 2 new: a right click on the root
    name offers exactly [lib-menu-collapse] while the name still reads "Roll A",
    and one click takes the fully open roll (4 rows: the picked folder, its
    subfolder, the subfolder under that, and one holding no frame) to a single
    row. The fold is measured against the ruler of opening the root back up:
    the 3 rows that return are CheckRoll, CheckRoll/2026 and CheckRoll/Empty —
    CheckRoll/2026/04 is still shut, which is what says the deep row went with
    the fold and not just the root. The strip held its 2 tiles throughout, and
    the folder the visit was on (lib-node-CheckRoll/2026) is what the reload
    below still reopens on.

ponytail: only folding, no unfold-all to match — the click on a row already
opens it and the root's own row is one click away; add the pair when the column
routinely holds many picked folders and opening them one by one stops being
cheap.

3dtours 1cb2618fd7 web: count a roll as it is read, and open a frame without losing the count
Two holes left by the last change. A frame is opened with `window.location.href`
rather than a link, so the studio was still handed a fresh page and the scan with
it — every route out of the catalogue now goes through `go()`, which pushes the
address instead of reloading while a scan is in flight. And a row counted what was
filed away rather than what had been read, so it sat at zero for the whole of a
first scan: the catalogue's frames only reach IndexedDB in one batch at the end.

`ScanProgress.counts` carries the frames the scan has reached, per row, off the
scan's own bookkeeping, and the column reads it while the scan runs — the row
under the reader's eye moves as the roll is read, and the toolbar's line stays the
whole picture. A re-read counts from the start, which is what it is doing.

The regression check grows the two: a frame opened mid-scan from the catalogue
(of a roll it already holds) has to stay in the page, and the row has to count.
2026-09-28 20:39:51 +07:00
3dtours 79b0d0db86 web: keep reading a roll while the studio is up
The catalogue hands the visitor to the studio with a plain `<a href>`, and the
app has no router: following it threw the page away, so a scan that was halfway
through a roll died with it. A scan belongs to the tab, not to the screen that
started it.

The scan now lives outside the component (`scanSession`/`startScan`/`stopScan`,
watched by whoever is up), so the catalogue can unmount and come back to a
reading that never stopped; a screen that returns joins it and sees the toolbar
line, the stop button and the rows filling in. The internal links are taken over
for a history push *only while a scan is in flight* — everywhere else the
browser navigates exactly as before, so the landing-to-studio flow is untouched.

`scripts/scan-nav-check.mjs` is the regression: a roll read one frame at a time
off a slow server, handed to the studio mid-scan, back to the catalogue, and the
whole roll read to the end with the studio up, counting documents along the way.

the bottom. A folder being read turns a ring on its own row, the column is

3dtours 4c65923eff web: rename a folder, and add one from the empty column
A folder's own menu gains a rename, which paints a label over the folder
without moving it — the frame ids and the recipes hang off the directory's
name, not the label. The empty part of the column answers a right click
with ADD FOLDER, the FOLDERS heading goes (the count already rides on
each row), and the column narrows to 118px so the stage takes the room.

3dtours d1abda141a web: browse the catalogue as a tree of folders
The library page was a flat wall of thumbnails. It now reads like the admin
pictures tab: a folder tree on the left, the picked node's frame on the stage,
that node's frames in the strip below, and a chip pair to swap the stage for a
wall of every thumbnail in the node.

Folders are walked recursively (dot/@-prefixed names skipped, an unreadable
subfolder is dropped rather than failing the scan), so a roll with a dated
subfolder keeps both levels. Node counts include the subfolders underneath.

3dtours 81637b8502 web: a catalogue of the folders on the visitor's own disk
A RAW studio that cannot see a folder is one photo at a time. /library
now takes a folder through Chromium's directory picker, keeps the handle
in IndexedDB so the folder is there on the next visit, and walks it into
a grid: one thumbnail per frame, the frame's own date, and the recipe it
was last graded with. Nothing is uploaded and nothing is read twice —
the RAW itself is opened only when a tile is clicked, at which point the
studio develops it and the recipe comes back on top. The studio files
every change back against the frame, debounced, so reopening a RAW is
not doing the grade again.

Thumbnails come off LibRaw's unpack_thumb for a RAW, which is a seek and
a copy where a develop is a full decode of every pixel, and off
createImageBitmap for anything else. A RAW with no preview inside it
gets a placeholder tile rather than a minute of decoding per file.

3dtours 0f2e109aa2 web: make the studio installable, and give it a shell that opens offline
The three things a browser asks for, without a plugin: a manifest in
public/ (name, /app as the start, three icons cut from the one piece of
art this repo has), a service worker, and the two metas iOS reads
instead of the manifest.

The worker caches the shell — /, /app, /library, all one document under
the SPA fallback — and the hashed assets the build emits. A navigation
is network-first, so a deploy is never pinned behind the cache; a
hashed asset or the wasm is cache-first, because under a given build
those never change. /api and any non-GET go straight out: a worker is a
cache, not a proxy. nginx serves sw.js and manifest.json `no-cache`
(both names outlive their contents) with the isolation headers the
worker script needs under COEP.

The offer is the app's own dialog, not Chromium's mini-infobar: the
event is held, and it is spent either after the visitor has been in the
studio two minutes or the moment an export lands — the point at which
the app has done their work. Safari never fires the event, so it gets
the Share > Add to Home Screen line instead. A refusal is remembered and
never asked again.

3dtours d1e9425b9c web: read a frame's white off its pile, not off its largest sample
sensorWhite hung its nine counts of window off the plane's largest sample. A
hot pixel sits hundreds of counts above the level the sensor stops at, so on a
frame that carries one the window held the stray alone, found no pile in it, and
handed the develop the factor two instead of the frame's own level.

Measured on a Panasonic DMC-LX10 RW2: one sample at 15993 and one at 14665 over
a pile of 9,594,544 at 13855. The frame's level is 1.75x the fall-back, so the
develop opened 0.81 of a stop bright, clipped the sky the sensor had held to
flat, and the fit to the camera's preview could only pull the exposure back
after the highlight detail was gone. Against the camera's own JPEG of the shot,
mean |dL| 23.48 and dRGB +8.57,+0.90,+4.90 became 19.14 and +5.32,+1.89,+2.04,
and the level itself 7908 (gain 8.2872) became 13874 (gain 4.7236) against the
13855 the plane piled at — 0.14%, 0.002 of a stop.

The level is now the highest count the plane piled at, off a whole-plane
histogram: `floor` counts is a pile, and the same cliff rule as before still has
to hold over the count below it, so a smooth bright sky is left alone and a
frame that has not clipped still falls back on the factor two.

The same stray was in four of the ten bodies to hand. A Nikon _GDN0447.NEF read
the fall-back 8190 where its plane piles at 13806 (gain 8.0018 -> 4.6022, 0.79
of a stop), a Fujifilm RAF 29696 where the documented level is 30993, and a Sony
ARW 31742 against the 2.002x the body's ratio was measured at. Six were
untouched, and a Canon CR2 develops byte-identical through the change — the
window moves only on a frame whose largest sample is not its highest pile.

scripts/white-level-check.mjs keeps the LX10 shape: a plane piled at 30995 with
a stray above it has to answer 30995.

3dtours e6c050581f web: make AUTO write the tone and the colour it reads off the frame
The AUTO chip measured the photo and wrote one knob, EV. It now writes the four
the measurement actually names, off the same binned ramp (ui/Histogram.tsx),
which is why it is one chip and not four: the means it needs are all in the
histogram the exposure answer already reads.

  EV          the mean luma, unchanged
  HIGHLIGHT   the top 1% (p99 > 0.9 pulls back), to -5 of the ruler at most
  SHADOW      the bottom 1% (p01 < 0.02 opens up), to +5
  TEMPERATURE/TINT  the gain that puts the three channel means on each other,
              green as the anchor: gray-world on linearised means, then the
              closest of 76 temperatures x 21 tints under the renderer's own
              kelvinToRGB, so the pair cannot drift from what the ruler applies.

The ends rather than the average is what keeps a small blown window from
dragging the whole frame: a specular in the corner wants HIGHLIGHT, not a
flatter picture everywhere. Both ends stop at half the ruler, so the frame is
corrected and a hand can still finish the move; the knobs then report the
numbers AUTO chose, the way the EV knob does.

Each reading is a pure function of the ramp, so pressing AUTO twice lands on the
same recipe by construction, and a frame with a dead channel leaves the WB ruler
where it is rather than inventing a cast. ponytail: one linear ramp per end and
no scene analysis; add a curve, or weight by how much of the frame is clipped,
when AUTO starts overshooting a scene with a genuine specular in it.

scripts/auto-tone-check.mjs holds the three readings: the percentile walk, the
thresholds that leave a knob alone, and the scan landing back on the gain it was
asked for.

3dtours 224ff0b935 web: open a RAW at the resolution of its sensor, not at the quarter of it
LibRaw's half-size demosaic was on. The Ricoh GR's own DNG (D0004128.DNG)
developed to 3010x2012 while the JPEG written beside it in the same second is
6000x4000, and the Fuji's RAF to 3008x2007 against its own 6000x4000 -- the
quarter was the flag, not the file. With `halfSize: false` the same develop
returns 6020x4024 and it is the sensor's frame on every body tried:

  D0004128.DNG  6020x4024   IMGP6916.DNG        6028x4024
  DSCF1701.RAF  6016x4014   _DSC0009.ARW        6024x4024
  AFXT2721.RAF  6246x4170   Nikon-D850 NEF      6216x4136
  _GDN0447.NEF  4284x2844   P1010607.RW2        3472x3472
  5G4A9396.CR2  2880x1920

Nine files, 27s to 155s a develop on one core. Checked through the app
itself, not only through LibRaw: photo-dims 6020x4024 on the DNG against
6000x4000 on the JPEG, both err none.

The colour it opens with is now fitted per file to the preview the camera wrote
into it (previewMatch.ts): a 3x3 over a block grid of the develop against the
same grid of that preview, then one cubic a channel for what the 3x3 leaves.
The offline per-body table this replaces (cameraMatch.ts) stopped matching the
moment the path under it changed -- its rows no longer summed to 1 once the
highlight knee landed ahead of it -- and a body with a row opened with a cast
one without did not. The file's own preview does not age.

The white level the gain carries is the frame's own plateau rather than
`maximum` (sensorWhite.ts), a factor of 1.89 to 2.00 out; without it every
frame opened a stop bright and a body that sat lower (X-Trans, 1.892) never
reached the highlight desaturation at all.

The desaturation gate reads the gain-lifted levels as well as the sensor's,
which is the whole of the magenta: on a body whose cam_mul lifts red and blue
(the GR's [2.64, 1, 1.73]) a blown sky crosses the white level at 0.38 of the
raw range in red while green crosses at 1.0, so a gate read on the sensor's
levels alone stayed shut across it. Measured in the app against the camera's
own JPEG, mean dRGB over a 16x16 block grid: +1.20, -5.95, -6.11 with the
sensor's clip alone, +0.21, +0.24, +0.47 with both, mean |dL| 21.5 against
10.3. The same grid on the Fuji comes back balanced (+4.7, +5.0, +3.6) and best
aligned at offset 0,0.

-HL is recovery and +HL is a lift, so they are different moves now: recovery is
the doc's soft knee in linear light over the top half, which is the only term
in the tone shader that is not a shift and the only one that can put detail
back into a blown sky rather than merely darken it.

The four checks pin the develop down where it can only run in a browser:
raw-develop-check, preview-match-check, white-level-check, highlight-knee-check.

3dtours b824308182 web: hand the RAW develop's plane to Skia as half, so the GPU keeps its shadows
An RGBA_F32 image with an sRGB tag comes back off the GPU backend sampled on a
1/255 grid; the same shader on a raster surface returns the floats untouched.
The plane is raw/65535, so the shadows the black level is there to keep sit at
1e-3 and quantise to zero -- a 3010x2012 develop landed 41189 pixels under luma
2 with the dark end speckled blue/yellow, against none on the raster surface.
A half is uploaded as float, so the plane stays exact either way.

Rejects the earlier guess that the render target's colour space was to blame:
gpu+rt-srgb and gpu+img-untagged came back byte-identical to gpu.

scripts/half-check.mjs checks the conversion: the named encodings, and no plane
value in a 14-bit sensor's range moving more than 4.8e-4 relative.

3dtours a9030fc0c0 web: give the GPU path a half-precision upscaler
The GPU export now runs the same upscaler in half precision. The chip is handed
2.34MB of weights instead of 4.88MB, and where its shaders can multiply in fp16
it does twice the work per pass.

`realesr-fp16.py` is the conversion, run on what `realesr-gpu.py` already
wrote (the PReLU-rewritten model), never instead of it. onnxconverter-common's
`keep_io_types` needed two of its own mistakes put right:

- It rewrites the consumers of the graph input but misses the one that never
  goes through the network. This model adds a Resize of the ORIGINAL photo to
  the upsampler's output, that Resize reads the graph input directly, and the
  runtime refuses a graph whose final Add mixes fp32 and fp16. The consumer is
  rewired onto the cast that `keep_io_types` should have sent it through.
- It also half-precisions Resize's `scales` — ONNX defines that input as
  float32 whatever the rest of the graph does, and a runtime that opens the
  file at all rejects the whole graph: "Type 'tensor(float16)' of input
  parameter (/Constant_output_0) of operator (Resize) is invalid", on the GPU
  as much as on the processor. The script widens it back and asserts it did.

The tensor the app builds stays float32 and the model's two Cast nodes are its
own edge, so nothing in superRes.ts or App.tsx has to know which copy it got:
205 nodes, 101 fp16 weights, io still float.

`openSession` asks for the model only where the adapter advertises
`shader-f16` — a provider without it emulates the type on the same file at the
same speed, so the smaller download would be the only thing gained. The order
is fp16 on the GPU, fp32 on the GPU, fp32 on the processor, each attempt
falling through on its own failure.

Measured on the rebuilt container (BASE=http://localhost:8090):
- fp16 vs fp32 on a 128x128 tile, same graph: max abs diff 0.0025 (0.65/255),
  mean 0.00028, psnr 71.0dB.
- sr-f16-chooser.cjs 4 PASS / 0 FAIL: on a forged adapter advertising
  `shader-f16`, the fp16 file is the FIRST model asked for; on one whose device
  refuses, the fp32 file is fetched for the processor and the 4K export still
  lands (7,555,377 bytes, 19.6s), no console errors.
- superres-test.cjs 32 PASS / 0 FAIL, sr-crop-export.cjs 0 FAIL,
  web-smoke.cjs 0 FAIL, sr-model-probe.cjs 0 FAIL.
- npx tsc --noEmit clean.

ponytail: the speed of the fp16 path is NOT measured — this container has no
WebGPU adapter (not even lavapipe/swiftshader, headed through xvfb), so every
export here runs the wasm fallback. sr-model-probe.cjs on a machine with a GPU
is what would show it.

Also worth noting for the next person: in a browser with no working adapter,
the runtime builds the device BEFORE it fetches the model, so no probe in a
GPU-less container can observe which model was chosen — a stub whose device
throws leaves the network silent. The chooser probe forges a device good enough
to be accepted for exactly that reason.

3dtours a0965101e1 web: hand the upscaler's activations to the chip that is running them
The WebGPU execution provider has no PReLU kernel. The model is 34 convolutions
with a PReLU after every one of them, so an export that took the GPU path was
split 33 times: each activation came off the chip to be activated on the
processor and went straight back, a 64-channel map in both directions, per tile.
A machine with a good graphics chip was not exporting any faster for having it.

PReLU(x) is exactly Relu(x) - slope * Relu(-x), and Relu, Neg, Mul and Sub the
provider does implement, so scripts/realesr-gpu.py writes the 33 activations out
as those four and drops the slopes nobody reads any more. The model file is the
output of that script, not the file as published.

One 256x256 tile through the model before and after, on a WebGPU session: the
runtime no longer reports nodes left off the preferred provider (it did, once,
before) and the processor path answers bit for bit what it answered before. The
warning itself cannot be switched off from here - env.logLevel is read when the
runtime module initialises, before any of this runs - so the graph was fixed
rather than the lines hidden.

3dtours c0c99a9672 web: EXPORT offers a size, and a bigger one is upscaled in the browser
The server still never sees a photo, so the model has to run in the page.
Real-ESRGAN x4v3 ships as a 4.9MB ONNX in public/models and is loaded
lazily on the first export that actually needs it; the wasm runtime is
copied next to CanvasKit at build time and stays lazily fetched, cached
for 30 days. Vite is told onnxruntime-web is external-wasm so no 28MB
asset lands in the bundle.

UNCHANGED keeps the old path and the tier cap; 2K/4K/custom upscale only
when the request is larger than the photo being edited, otherwise they
resize down. Guests keep UNCHANGED and 2K. Tiling is 256px with an 8px
overlap, so memory follows the target size rather than four times it.

3dtours 8c6e7930db Add self-contained docker/ stack for the web UI
`docker/` now holds the whole web build — frontend (Vite + React + CanvasKit),
backend (Fastify + SQLite) and the compose file — so the folder can be moved to
another machine and run without the React Native project:

    cd docker && cp .env.example .env && docker compose up -d --build

Only `${WEB_PORT:-8090}` is published; nginx serves the SPA and proxies /api to
the `api` container over Docker's DNS. Photos never reach the server.

The shared render code is vendored into `docker/frontend/shared/` and aliased to
a CanvasKit shim, so the app's own frameUtils/toneShader/jpegDpi run unchanged.

Fix the all-black render on GPU surfaces: `MakeWebGLCanvasSurface` creates a
separate WebGL context per call, and a texture from one context cannot be
sampled by a surface on another — so any pass that drew a snapshot onto a second
surface (output sharpen, screen sharpen, polaroid/wallframe cards) came out
solid black, while the raster fallback was correct. Use one shared
GrDirectContext + MakeRenderTarget instead.

Verified in headless Chromium against the running stack: 12MP JPEG in, preview
mean=120.5 sd=60.5, export 2048x1536 mean=107.2 sd=62.1, JFIF density 300/300,
EXIF present, no console errors; health/signup/login/me/recipes all 2xx through
the nginx proxy.
