With no shard results, ratchet.mjs threw, wrote no report, and the workflow
printed "Edit accuracy fell against the base branch" for what was a build or
shard failure. A shard that did not report was also counted as a drop. The
gate now exits 2 with "Edit accuracy did not run: N of M shards reported
results" when nothing that ran fell, writes its comment and report in that
case too, and the workflow prints the gate's own verdict.
* perf(studio): settle the edit accuracy bench on frames and network, not a fixed window
settled() waited for the box and the preview frames to hold still for 500 ms,
7 to 15 times a case. It now resolves once they read the same on 3 animation
frames in a row while the Studio page has no request in flight (the event
stream and server-rendered timeline thumbnails excepted) and the server has
announced every project file written since its last file-change event, so a
save, a preview reload or a reload the event starts still holds it open.
EDIT_ACCURACY_STILL_MS restores the fixed window with no network signal.
Also polls studio_seek every 50 ms instead of 250 ms while Studio opens.

* perf(studio): keep one producer Chrome open across edit accuracy renders
Every render launched and closed its own producer Chrome. The run now holds a
lease on the engine's pooled browser (a capture session with the renders'
launch settings and its page closed), so each render opens a page in that
browser instead. Each render still gets its own page and file server, and
clears the browser cache first. A held browser that failed to launch or whose
Chrome died is dropped and held again, never reused.
Studio's server stays per case: it serves one project folder, stamps it on
start and keeps that folder's undo history open, so switching folders under it
would leak history between cases. Its start is polled every 50 ms instead of
200 ms.

* fix(studio): seek the edit bench only after Studio binds the timeline
openStudio now polls every 50 ms, so after a reload its first studio_seek
often lands before the runtime binds the timeline (Studio still reports
duration 0, but the playhead moves). The bind then replays the playhead from
near 0 (core init.ts progress(0.0001) then totalTime). A tween that starts on
the playhead was already initialised by the early seek, so GSAP skips its
first keyframe. The preview then holds a box no fresh seek or render shows.
In resize-fromto-px-r0-nested-z100-on that box is 90 px off, and it persists
until the next seek.
Wait for studio_look to report a duration before seeking.

* perf(studio): cut fixed waits from the edit accuracy bench
- Settle window 1000 ms -> 500 ms (EDIT_ACCURACY_STILL_MS overrides it).
- Drop the fixed 1 s sleep in openStudio; the settle that follows is the
real readiness wait.
- Mark composition hosts data-no-timeline in the producer's page when the
saved project has no GSAP timeline, so the render skips the 10 s
playerReadyTimeout wait.
- Run the blank-page smoothness control once per gesture per browser.

* ci(studio): trim the edit accuracy grid to 741 cases
Drops zoom 200, the pct and center placements, and nested keyframed cases
from the grid (2061 -> 741 cases; the pr slice 435 -> 265). Drag paths and
sequences are unchanged.
baseline.json loses the 1320 removed cases. The ratchet no longer counts a
base case that the head's baseline.json does not hold, and lists such cases
as retired, so removing cases from the grid and baseline.json together does
not fail the gate.

* fix(studio): measure the blank-page control again after it fails
The control is cached per browser and gesture, so a rejected measurement stayed
cached and failed every later case with that gesture before Studio was tested.
Drop a rejected entry so the next case measures again.

* ci(studio): keep the nested keyframed resize cases in the edit accuracy PR slice
Two historical gate runs failed only on resize-scale-px-r0-nested-z100-on,
which the trim removed, so the PR slice would have passed that build. Keep
the nested keyframed resize on a keyframe at zoom 100 without rotation, one
case per GSAP mode, with their baseline entries. PR slice 265 -> 271 cases,
full grid 741 -> 747.

* ci(studio): run the edit accuracy slice on PRs and the full grid in the merge queue
The edit accuracy gate used about 83% of CI job-minutes, ran on changes that
cannot reach the bench (encoder, render and CLI command code), and never ran
in the merge queue, so main could drift and fail every later PR.
- Path filter: its own paths-filter step with some-with-excludes, limited to
what the bench runs: Studio, studio-server, core, parsers, player, sdk, lint,
the CLI preview server path, and the engine and producer modules in the
import closure of browserManager, frameCapture and both fileServers. Test
files, fixtures and docs no longer trigger it. The bench's webmcp-host.mjs,
which it imports but the old filter missed, now does.
- merge_group: the filter's base is the event's base_sha there. In the queue
the full grid always runs (20 shards) whenever the filter matches. The queue
is the last point before main, and nothing else measures the full grid
now that PRs run a slice. Skipping it would let zoom 50/200 and rotated
regressions land on main, where they fail every later PR against the
banked baseline. That drift caused about a fifth of past gate failures.
- PRs: the existing `pr` grid becomes zoom 100 with no rotation in both
nestings (435 of 2061 cases), in 5 shards. Of the 11 PRs whose real
regressions the full gate caught, this slice held a regressed case for 10.
- Gate: newly passing cases missing from baseline.json are listed in the
comment and as a notice, not failed (45% of past gate failures). A partial
grid compares only the cases it ran. `--shards` fails the gate when a shard
reported no results, and only a full grid writes a bankable baseline.json.
- The required check "Studio: edit accuracy gate" keeps its name. It is
skipped when the filter does not match, as before.
- check-test-reachability models negated globs as exclusions under
some-with-excludes and still fails closed elsewhere.

* ci(studio): run the edit accuracy gate when its install inputs change
The path filter missed the root package.json, the dependency install script
and the ffmpeg setup action, which Build and every shard run. A change to any
of them could alter the bench while the gate skipped. Add them, and a test that
every local input of the jobs that build and run the bench is in the filter.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
* ci(edit-accuracy): cover transitive bench inputs in the path filter
The filter test now walks the files the bench actually runs: the bench
entry files, their relative and @hyperframes/* imports, the CLI commands
the bench invokes, and the build scripts, configs and files those builds
read for every package the bench reaches. Globs are matched with
picomatch, the matcher dorny/paths-filter uses.
The walk found 183 inputs the filter missed, including the producer's
frameCapture.ts, build-hf-early-stub.ts and stubs/hf-early-stub.ts, the
engine services behind engine/src/index.ts, and the CLI browser command.
The filter now covers them.
picomatch is not in the no-install Test reachability job, so the filter
test moves to test:scripts.

* fix(studio): a resized corner stays on the pointer when the size rounds to whole pixels
Resized sizes stay on whole CSS pixels (GSAP centres a -50% translate from the
integer offset size), so the centre-anchored resize left the grabbed corner up to
a third of a pixel times the element's scale off the pointer: 0.53 px on a 1.5x
scaled layer. The centre pin now takes half the rounding remainder along the
element's rendered edges, so the grabbed corner lands where the wanted size puts
it while the written size stays whole.
* fix(studio): a scale resize saves the box exactly where it was dropped
finalizeScaleResizeCommit skipped its position correction whenever the box sat
within 0.5 px of the drop point on each axis, so a sub-pixel drop (now the
norm, with the grabbed corner on the pointer) saved up to half a pixel off.
It now skips only when the correction rounds to nothing at the precision the
file is written in.
* fix(studio): a scale resize lands centred on the box that was dropped
finalizeScaleResizeCommit lined the committed box up with the drop by its
top-left corner. When one scale cannot reproduce the dragged width and height
(the draft rounds each to whole pixels), that put the whole gap on the far
edges, up to half a pixel. The resize is centre-anchored, so it now lines up
centres and the gap splits evenly.
* chore(studio): keep the complexity note on the resize intercept, not the new helper
* test(studio): bank the two scaled resize cases that now pass the edit accuracy bench
* fix(studio): a scale resize leaves animated positions alone and mirrored corners track
* test(studio): bank only the two newly passing scaled resize cases
* fix(studio): a mirrored or parent-rotated layer's resize corner tracks the pointer
* fix(studio): a resize corner on a skewed layer picks its side from the box's own edges
* fix(studio): resizing a layer that renders with no area moves nothing
* test(studio): bench moves pressed right after Add keyframe
* fix(studio): an undo that reloads the preview keeps the selection, so a drag after it moves
* fix(studio): a drag started while a resize saves keeps its animations paused
* fix(parsers): an edit pins no position on a keyframed tween it did not touch
* fix(studio): a move pressed while the preview changes lands on the new preview, at the time pressed
* test(studio): bench waiting presses, a held box resized twice, and reloads at the last playhead
* refactor(studio): tidy the waiting press, bound its wait, and freeze edit stamps after early exits
* test(studio): load the property panel once so its first test stops timing out
* fix(studio): presses queued on a held box keep their release, hover and newest outline
* test(studio): judge bench undo by the history groups Studio claims, not by file writes
* refactor(studio): one waiting-box lookup in the bench and one raf-pause write per release
Behaviour-identical tidy of the waiting-press work: the bench reads the waiting
box through one helper, releaseActiveGesture sets the raf pause once, clearPointerState
writes the false it always computed, and previewGestureStarts calls the opts setters
directly instead of through aliases named like the gesture hook's gated setters.
* fix(studio): a queued press lands on the element it pressed and survives a window switch
* fix(studio): undo cancels a waiting press, a stuck save stops holding presses, scene swaps hold them
* refactor(studio): keep the complexity waiver on clearPointerState itself
* fix(studio): undo of a queued press leaves nothing waiting, and hosts keep their own undo
* fix(studio): a waiting press keeps the box still after a blur, and undo reports what it took back
* style(studio): bring the PR's comments within the comment limits

* test(studio): keep the plain-to-keyframes moves inside the nested frame
* fix(studio): a resize moves its anchor from the drag stamp it read at release
* fix(studio): an undo shown in place is no longer replaced by an older reload
* refactor: split the trailing keyframe trim and drop an unused GSAP reader
* test(studio): settle the resize-then-drag bench steps so a two-save resize is one undo
* fix(studio): a preview reload waits for an undo shown before its write lands
* fix(studio): Add keyframe reads a subtracted calc() translate with its sign
* refactor: tidy the keyframe hold, trim and resize code after review
* fix(parsers): the keyframe trim leaves looping, chained and relatively placed tweens alone
* fix(parsers): a size hold pins only a lone key, so an edit never changes frames left alone
* fix(studio): every undo applied in place counts as a preview change, script-only ones too
* fix(studio): a resize keys size only when a move or size is keyframed, not a fade
* test(studio): a bench step whose save never lands fails the case
* fix(parsers): holds and trims change only the tweens an edit touches
* test(studio): bank the plain-to-keyframes and resize-then-drag bench cases
* test(studio): the edit bench checks the keyframe rule outside a range and for new property groups
Adds playheads before a range that starts late and after every range to the
keyframed grid, and fails the keyframe rule when an edit makes the timeline
animate a property group (position, size, scale, rotation) on the target that
nothing animated before.
* test(studio): trim the keyframe-rule bench comments to the comment ratchet

* test(studio): skip the same non-animated keys as the parser when grouping
* test(studio): bank the keyframe guard cases from this head's gate run
* fix(core): a cropped element's edge stays exact while GSAP tweens it
* fix(core): configure GSAP while the runtime script runs, before compositions set elements
* test(studio): bank the six crop-scale cases that now pass
* test(producer): regenerate the png-sequence and mov-prores goldens for 2D GSAP transforms
* test(core): a non-configurable window.gsap is configured without a crash
* test(studio): re-bank the edit accuracy baseline from this branch's current head
* test(studio): the edit bench render serves GSAP from the repo, never the CDN
* test(studio): the edit bench render opens no second page that fetches GSAP
* test(studio): the render test checks the CDN pattern matches the fixture's GSAP URL
* test(studio): match the CDN pattern the way Chrome does
* test(studio): the render test checks the whole interception pattern
* fix(parsers): a keyframe edit no longer overrides an earlier tween at the start
Writing a keyframe into a tween that starts later added a t=0 hold for every position prop of
its first keyframe, so a from() that already moves x before it lost its start value. The hold
now skips props an earlier tween on the same target writes; both writers share one helper.
* fix(parsers): keep the hold for label-placed tweens and re-sync one-line scripts stably
The recast parser leaves a label start unresolved; an unknown start no longer counts as earlier,
so the hold stays. The acorn insert now ends the hold on its own line when the next statement
shares the timeline line, matching what removal takes, so a second sync changes no bytes.
* fix(parsers): the recast hold sync reads tween starts from the acorn parse
The recast parser cannot resolve label positions, so an earlier label-placed tween looked
unordered and kept a hold it should not. Both writers now decide holds on the same parse.
* revert(parsers): keep the recast hold sync on its own parse
Deciding recast holds on the acorn parse lost selectors only recast resolves (an element bound
through a helper). Recast is the migration fallback and keeps its old hold for a start it cannot
resolve; the earlier-label case is decided by the default acorn writer, which resolves labels.
* style(parsers): name the hold insert's line ending instead of commenting it
* style(parsers): fit the hold helper's doc in four lines
* test(studio): bank the from/to edits this fix makes accurate and the resizes #4920 fixed
* test(studio): serve the edit bench GSAP from the repo, never the network
* test(studio): serve the installed gsap dist and never crash the bench on a closed request
* test(studio): serve only regular files from the bench gsap dist
* fix(studio): an undo or drop on an animated layer keeps it where it was
* test(studio): bank the edit accuracy cases the soft reload fix makes pass
Spliced from gate run 37151157876 (merged with main 7dea1e58): the 207 newly passing lines only, byte for byte; every other line is main's.
* fix(studio): an edit on a GSAP-animated layer writes its value at the playhead into the file's tween
* fix(studio): undo pressed while an edit saves undoes that edit, not one started after the key
* fix(studio): an edit stays saved when the history reply after it cannot be read
* feat(studio): export ColorField and GradientField; a session style commit takes a map
* refactor(studio): name the map form instead of commenting it
* feat(studio): a host can move layers by exact film px, one undo per call
handleDomGroupMoveBy(moves) on useDomEditSession and DomEditValue moves each
selection by its delta in composition px, for Desktop's align and distribute.
It reuses the group drag's own path: a drag member per element (press-time
route, measured offset map), the delta carried to screen px through the
preview frames, then handleGsapAwareGroupPathOffsetCommit, so one shared
coalesce key gives one undo entry and GSAP members take the GSAP write.
A member that can't move refuses the call before anything is written; the
refusal rejects with its reason and shows no Studio toast (the group commit
takes refusalToast: false; telemetry stays). Zero deltas are skipped.
Tests: a pre-offset element and one under a half-scale parent move by exactly
{10,0} and {0,-5} under one group key; a half-scale parent with a 30 deg
rotated ancestor lands within the 0.001 px a translate is written with; a
GSAP member goes through the GSAP write; three refusal kinds write nothing,
leave the boxes where they were, show no toast and leave no gesture mark,
while a canvas group drag still toasts; the session hands the call to the
group commit with refusalToast: false. Each mutation (no frame mapping, no
zero skip, no restore, no teardown, no capability check, toast on refusal)
fails at least one of them.
* fix(studio): an outside change during a drag waits for the drop to show
While a gesture mark is live in the preview, refreshPlayer takes the shadow load instead of
swapping scenes in place. A swap replaced the node under the pointer mid-drag; the shadow load
is then held by the existing gesture hold and, if the drop saved, reloaded fresh by the stale
rule, so this adds no second "released" signal.
Test: an outside change during a live drag on a preview that can swap scenes leaves the dragged
node in place, shows nothing under the pointer, and after the drop loads fresh with the dropped
position. It fails on the parent without the condition ("swapped under the pointer").
Cost case, measured in a real headless preview on the edit-accuracy bench's per-frame teleport
check. Every GSAP instant patch was forced to miss and fall back to reloadPreview during its own
commit; move and rotate of a held element (gsap.set and tl.set holds), px and xPercent
placement, r0 and r30, root and nested, at 100%:
- The gesture mark was live when the fallback asked for the reload, but had always ended by the
time refreshPlayer ran (refreshKey is consumed in an effect after the commit settles). So the
new condition never fired there: root previews offer no scene swap and load shadow on both
builds, and nested previews swap on both builds.
- Worst post-release frame offset, 32 cases on this build and 32 on the parent: 0.00 px over
76-106 frames each (release to settle). No frame was off by more than 0.5 px.
- Sensitivity: a 3 px nudge injected 50 ms after the fallback reads back as 3.00 px.
* fix(studio): an edit no longer reopens the live-updates stream, and thumbnails ask one at a time
* fix(studio): an undo no longer waits behind paused preview videos for a connection
* feat(studio): a host whose API needs same-origin cookies can have Studio send them
* docs(studio-server): a host on same-origin cookies sets the Studio credentials opt-out
* test(studio): an undo is not held up by the preview's paused videos
* fix(studio): a resize inside one gesture writes a mixed tween once, in place, never beside it
* chore(studio): keep the carried fixes inside the comment ratchet; telemetry posts through studioApiFetch
* test(studio): a drag on a mixed tween is one write under the gesture key
* fix(studio): freeze-frame, loudness and peak-map requests go through studioApiFetch too
* fix(studio): an undo with no project open reloads in full instead of skipping nested files
* refactor(studio): drop the soft reload's reparse seeding, the held-element sweep covers it
* test(studio): keep the undo-restore browser test off the network and inside its timeout
* test(studio): nested composition reads expect the cookie-free request studioApiFetch sends
* fix(studio): an edit at the playhead rewrites its tween in place, so later tweens keep their times
* fix(studio): a rotate on a tween that turns another axis holds its angle and never turns early
* fix(studio): plan every group member before the first write so one refusal moves none
A group drag or nudge preflighted each member against the move refusal rule only. The value-at-playhead planner ran later, in the commit loop, after earlier members were already flushed to disk, so a tween with extras, eased keyframes or an unknown ease left the group half moved.
The group preflight now runs the commit's own route and keyframe plan for every member with its real offset, so any refusal refuses the whole group with nothing written and one toast attributed to the refusing member. The plan is not reused in the commit: earlier members' writes change the file under it, so each member re-plans against the fresh tween, from the same planValueEdit.

* test(studio): quarantine the nudge sequence whose redo waits behind preview videos (#4889)
* test(studio): bank the 255 keyframed edit cases that pass
* fix(studio): a hand drag moves only with its own pointer pressed
Chromium re-sends the last known pointer point with no button held after a
layout change. The overlay's move handler took those as drag travel, so the
element flipped between the pointer and that stale point, and the release
committed whichever came last.
* test(studio): the edit accuracy grid drops a drag after a buttonless move at the press point
Nine pathstray cases: a 180,90 drag whose last move before the release is a buttonless pointermove back at the press
point, as Chromium resends after a layout change. Main saves the element where it started; this head saves it where
the pointer let go. The frame sampler ignores that untrusted move as pointer position.
* fix(studio): keep the drag rule's comment to one line
* fix(studio): crop handles and the marquee band also ignore a buttonless move mid-gesture
* test(studio): bank the nine stray-move cases in the edit accuracy baseline
* test(studio): one crop drag helper, the band's candidate refresh in its own step, and formatting
* style(studio): wrap the pointer gesture comment under 120 characters
* fix(studio): undo paints a move or nudge back at once while its save is still running
* test(studio): the edit accuracy gate judges the two part C sequences again
* fix(studio): a save lasts until undo can paint it from the history
* test(studio): the bench reads the box after a key's frame, as a user sees it
The nudge step already waits a frame per key (sequences.mjs:162); undo and the text step's Enter now do too.
* refactor(studio): say which registrations a pending edit adopts
* fix(studio): resizing an element GSAP only positions saves its CSS width and height
* fix(studio): a resize never saves GSAP's scale mask as the element's CSS
* fix(studio): keep the resize size writer inside the file and comment budgets
* fix(studio): a GSAP-positioned resize saves its CSS size before the GSAP write renders
* fix(studio): undoing a crop leaves a GSAP-animated layer where its file puts it
* test(studio): an undo on a GSAP-parsed layer in a two-script file reloads the preview
* fix(studio): a move keeps an authored xPercent centring set in the saved file
* fix(studio): a drag on a centred element no longer flashes off-centre on release
* fix(studio): a font pick saves the edit and its @font-face in one write
* fix(studio): a focused combobox, switch or plain-text editor counts as an unsaved edit
* test(scripts): pin that a slash after i-- before a quoted slash is division
* fix(studio): an inspector edit saved while a preview reload loads stays on screen
* fix(studio-server): a font save accepts exactly one @font-face rule and nothing after it
* fix(studio-server): a font name or path with braces in quotes still saves its @font-face
* fix(studio-server): a CR or form feed in a quoted font name cannot end the @font-face rule
* test(studio): bank the 99 edit accuracy cases the GSAP fixes now pass
* fix(studio): undo right after an edit undoes that edit, even before its save lands
* fix(studio): undo right after a nudge undoes the nudge
* fix(studio): undo during a nudge's wait for more keys never paints the edit before it
* fix(studio): a failed save never blocks undo, and a nudge burst always ends its pending edit
* fix(studio): undo waits out every failed or conflicting edit, and Delete counts as pending
* fix(studio): every GSAP script commit counts as a pending edit, so undo waits for it
* fix(studio): keep App under the file size limit
* test(studio): bank the nudge-then-undo sequences the gate now passes
* fix(studio): an undo that lands mid-drag keeps the box under the pointer
* fix(studio): an undo that lands on a pressed layer keeps what its gesture draws
* fix(studio): every gesture mark names what it draws, and a text edit draws nothing
* test(studio): gate the drag, undo, drag cases again now that their race is fixed
* fix(studio): a text edit's gesture mark draws nothing, so an undo under it reverts
* test(studio): keep the one drag, undo, drag case whose press can still jump in quarantine
* test(studio): bank the drag, undo, drag cases that now pass
* fix(core): a composition made only of a set shows it at a seek in the preview
* chore(core): keep the comment share of the runtime init file level
* test(studio): bank the four resize-hold rows the preview now gets right
* fix: a save's temp file no longer reaches Studio as an outside change
* refactor: the project file walk and its tests carry no new duplication or complexity
* test(studio): the edit accuracy gate judges the two nudge sequences again
* test(studio): catch teleports and multi-step edit bugs in the edit accuracy bench
* test(studio): share the edit accuracy case harness between single gestures and sequences
* test(studio): keep edit accuracy helpers private unless shared
* test(studio): score plain-CSS edits on pages that load GSAP for other elements
* test(studio): add an idle GSAP axis value so plain-CSS edits are scored on GSAP pages
* test(studio): report a slow undo save as late with its latency, apart from a lost one
* test(studio): sample the gap between back-to-back drags and allow one frame of lag
* test(studio): read the edge from the element's fractional size, so a crop edge is exact
* test(studio): keep waiting for a late save until an undone file stays put for 3 s
* ci(studio): run the edit accuracy grid in 12 shards to stay near 25 minutes each
* test(studio): read edit bench frames just before paint, so unpainted states never count
* test(studio): scope the edit bench frame sampler so page globals cannot clash
* test(studio): let a lagging box catch up the pointer travel it owes, so a held frame is no jump
* test(studio): record every save a sequence makes, even two that land 10 ms apart
* test(studio): end a drag's teleport scoring at its pointer-up, not at the next element's press
* test(studio): bank for each edit accuracy case a run that agrees with the gate's verdict
* test(studio): fail the edit accuracy gate on a teleport or an unmeasured drag
* test(studio): fail the edit accuracy gate when a text edit is not saved or shown
* test(studio): measure but do not gate the edit accuracy cases a known Studio race flips
* test(studio): bank the edit accuracy cases that newly pass with the teleport metric
* test(studio): quarantine the two nudge sequences whose redo write sits at the 2 s limit
* style(studio): cut three bench comments to one line each
* fix(studio): undo and redo are no longer held behind thumbnail renders
* test(studio): composition card tests share one mount, and the bench's 2 s undo rule is tested
* fix(studio): a composition card and its timeline clip share one thumbnail render
* test(studio): bank opening a film at 15 thumbnail requests, one per composition
* fix(studio): composition cards load near the viewport and keep their last frame until the next
* fix(studio): a composition card keeps its last frame under cache pressure, and loads 200 px early
* fix(studio): a rotate GSAP does not own saves where you let go, as the element's own CSS rotate
* fix(studio): a rotate keeps a transform-centred element in place
* fix(studio): a plain rotate shows its angle in the panel and turns inline elements too
* fix(studio): a rotate turns a mirrored or stretched centred element with the cursor
* fix(studio): keep the rotate's panel readout within the comment budget after the move landed
* fix(studio): an inline element's turn saves the inline-block it was drawn with
The overlay passes the rotate target it read at press into the commit, so the
save draws and patches exactly what the draft did instead of re-reading an
element the draft already made inline-block. The GSAP-aware commit also routes
on that press-time decision.
* test(studio): bank the 27 rotate cases a GSAP-free rotate now passes
baseline.json is the edit-accuracy-gate artifact of the CI run at cb75cc37,
copied byte for byte: 530 to 557 passing, all rotate-none cases, none
regressed.
* fix(studio): a word an older Studio turned keeps its inline-block and whole angle on a new rotate
Clearing the legacy rotation marks puts the element back to inline and drops
their turn, so the save reads the target again instead of using the one the
press read before the clear. A test also pins that a turn the press drew as CSS
stays on the CSS writer.
* test(studio): bank the edit accuracy baseline from the rebased rotate run
* fix(studio): resize an element without GSAP by its own width, height and translate
A corner resize of an element GSAP does not size or position now saves plain CSS:
its inline width and height, the scaled crop, and the translate that keeps its
centre where it was, in one save and one undo step, with no animation read and
no preview reload. It used to write a GSAP script into a file that had none, and
the box snapped back to its old size on release.
The anchor that keeps the centre planted is the same plain px translate a move
writes, kept to a thousandth of a pixel, and a percent translate is held as px
from the press so a growing box cannot drag it along on the first frame.
* fix(studio): a resize leaves a box to GSAP when GSAP tweens anything the CSS box writer sets
gsapWritesBox now reads its channels from BOX_SIZE_STYLE_PROPS, the writer's own
property set, instead of width and height alone. A host-level test pins the
GSAP-free resize route through useDomGeometryCommit.
* fix(studio): a GSAP scaleX or scaleY tween also keeps a resize on the GSAP route
They are GSAP's names for parts of the one CSS scale the box writer sets.
* test(studio): bank the edit accuracy cases a plain-CSS resize now passes
baseline.json is the edit-accuracy-gate artifact of the CI run at 5ae51f1d,
copied byte for byte: 494 to 530 passing, the 36 resize cases without GSAP,
none regressed.
* fix(studio): move and nudge an element without GSAP by its own CSS translate
* fix(studio): route a GSAP-free move through the on-element writer and meet the file checks
* fix(studio): a drag press on a GSAP page leaves an element GSAP does not position alone
* fix(studio): a press reads a percent or calc translate without touching the element
* refactor(studio): import POSITION_CHANNELS from its owner instead of a re-export
* test(studio): share the drag press helper in the start gesture tests
* refactor(studio): split the translate length reader into term and sum
* test(studio): cover each translate form the reader resolves or hands to Chrome
* test(studio): bank the edit accuracy cases plain-CSS moves now pass
baseline.json is the edit-accuracy-gate artifact of the CI run at 2a84c103, copied byte for byte: 60 newly passing cases, none regressed. The commits since change no behaviour (a reader split and tests).
* test(studio): gate edit accuracy against the base branch baseline
Work in progress: the ratchet and its tests; the CI job follows.
* test(studio): run the edit accuracy gate in CI across eight shards
Shares the built CLI from the Build job, re-runs twice each case that passes on the base branch and failed, and posts one sticky comment from the gate job.
* test(studio): mark the ratchet accuracy check as intentionally branchy for fallow
* test(studio): confirm newly passing edit accuracy cases 2 of 3 before banking them
The shards re-ran only regressions, so one lucky pass of a base-failing case failed the gate as unbanked and was never listed as unstable. Every case whose verdict differs from the base branch, either way, is now re-run twice and judged 2 of 3. A render error fails the gate like an unsettled snapshot, a malformed baseline.json fails the job instead of reading as empty, and the header is 3 lines.
* ci(studio): run the edit accuracy gate for every package the bench builds or imports
* ci(studio): also run the edit accuracy gate for lint, sdk and the Studio and CLI build inputs
* ci(studio): run the edit accuracy gate when a bench package's manifest or exports change
* test(studio): bank the 120 edit accuracy cases that sub-pixel dragging now passes
* test(studio): measure render drift against a producer frame in the edit accuracy bench
Finds the target's box in a producer-captured frame by its flat colour, with sub-pixel edges from area moments, and compares it with the reloaded preview. The baseline gains the render column from the same full run on main.
* test(studio): mark the pixel box scan as intentionally complex for fallow
* test(studio): regenerate the edit accuracy baseline with render drift on main
Same full run on main 14e87005d as #4760's baseline, with the render column: render passes 618/660, 70/660 pass, 314/660 pass everything but smoothness.
* test(studio): fail only render drift when the producer cannot render a case
A producer capture failure used to turn the case into a harness error that wiped every accuracy metric. It now sets render to null with renderError, fails render alone, and is counted in the table.
* test(studio): shorten the render drift box comment to two lines
* test(studio): start an edit accuracy benchmark for manual editing (work in progress)
* test(studio): an edit accuracy benchmark for manual editing
Drives real pointer and keyboard gestures in the built CLI Studio on generated one-element projects and scores tracking, drop jump, reload drift, undo fidelity and smoothness in composition px.
* test(studio): move render drift out of the first benchmark PR
Render drift against a producer frame ships in the stacked follow-up so this PR stays near the size budget.
* test(studio): keep the edit accuracy bench clean under fallow
Builds the grid as a product of its axes, drops unused exports and marks the harness functions that fallow scores as complex.
* test(studio): report edit accuracy with the Studio and bench commits it measured
Moves scoring and the report files into report.mjs, stamps both commits at start, counts undo byte failures apart from the worst box, and survives Studio swapping the preview iframe mid-read.
* test(studio): bank the edit accuracy baseline measured on main
660 cases on main ae914334f: 0 pass all six checks, 304 pass everything but smoothness. Five cases that hit a harness error in the full run were rerun and spliced in.
* test(studio): state the edit accuracy build prerequisite in the runner header
* test(studio): keep the edit accuracy baseline one line per case under the formatter
* test(studio): store edit accuracy baseline values rounded up
Rounding to the nearest 0.01 stored seven 0.502 px tracking results as 0.5, which reads as a pass at the 0.5 px limit.
* test(studio): score edit smoothness on dropped frames and main-thread work per frame
* test(studio): measure edit accuracy on a still preview and score press jump
Snapshots wait for the preview frames and the box to hold still for 1 s, so Studio's asynchronous reload after a save is measured, not raced. A preview that never settles fails the metrics it feeds instead of erroring.
Adds press jump (box at press against the box before it, 0.5 px). Smoothness counts only dropped frames beyond a blank-page control driven the same way in the same Chrome; unknown trace data fails smoothness alone.
The runner takes the suite lock per chunk of 8 cases (--lock), reads the port Studio announces, keeps undo history and tmp projects inside the case dir and removes them on a signal, and stamps the CLI tree's commit and bundle hash.
* test(studio): stamp the edit accuracy build with the Studio bundle as well as the CLI
The CLI bundle hashed the same for two different Studio builds; Studio's index.html names its hashed assets, so the stamp now covers it.
* test(studio): regenerate the edit accuracy baseline on main after the settle fix
Full grid on main 14e87005d with the settle fix, press jump and the smoothness control: 70/660 pass, 314/660 pass everything but smoothness, 0 harness errors, 0 unsettled. Scored without render, which #4764 adds.
* test(studio): wait for each edit accuracy undo write before sending redo
Undo and redo each wait up to 15 s for their own write, like the settle; redo is sent only once undo landed, and a write that never lands fails undo with undoTimeout instead of scoring an untested redo. The reload waits for the files to hold still. The headline is now the accuracy count, with smoothness on its own line against the control. The settle compares each read with the window's first read, and a CLI outside a git tree no longer stops the run.
