The codex image provider's fail-fast gate required an `imagegenext` row in
`codex features list`. Codex CLI 0.145 renamed that flag to `image_generation`
and dropped the old row, so the gate rejected every up-to-date CLI:
media-use: codex image upsell unavailable: codex imagegenext unavailable
(upgrade Codex CLI)
`resolve --type image --provider codex` returned that without ever attempting
a render, on hosts where image generation works fine. Codex itself now warns
`[features].imagegenext is deprecated. Use [features].image_generation`.
Resolve the flag name from the feature list instead of hardcoding it, and pass
whichever name the installed CLI exposes to `--enable`. The old name is
preferred when present, since CLIs that still list it reject the new one.
`codexUnavailableReason()` now returns `{ flag }` / `{ reason }` so the
resolved name reaches the exec.
Verified against codex-cli 0.145.0: `resolve --type image --provider codex`
generates and freezes an image. New unit tests pin both flag layouts so a
future rename fails loudly instead of silently disabling the provider.
The narrowing this branch adds missed the motion-path overlay, and every
caller that could not narrow fell back to the exact bare class the narrowing
exists to replace.
- motionPathSelection.selectorFor now goes through writeTargetSelector. It
feeds both the geometry read and the "set destination" write, so a class
sibling measured its home off the FIRST sibling and then authored
add-motion-path onto all of them. The toolbar toggle hides when no
one-element form exists rather than arming a press that is dropped.
- The five new-tween writers that fell back to the selection's own selector
now drop the commit instead. A gesture that does not persist reverts on the
next reload; a tween silently aimed at five elements does not.
- tweenTargetsElement only follows the DOM to a target that matches exactly
one element. A target the element merely shares with its siblings is a group
tween, and these callers mutate what they find, so an individual nudge was
rewriting the group's own tween and moving all five.
U3 fixed "add keyframe at playhead" widening a write to every sibling
sharing a class, but wired writeTargetSelector into only two paths. The
same bug was still reachable from the add-animation button, drag, resize,
rotate, gesture recording, and the property panel: each derived its target
from selectorFromSelection, which hands back a bare class for an id-less
element, so one edit authored a tween over all five siblings and the
timeline collapsed their rows into one.
Route every path that authors a NEW tween through the existing ladder:
- ensureElementAddressable now accepts selection.selector only when it
addresses exactly one element, so the id-minting fallback right below it
(previously unreachable whenever any selector was present) does the work.
- gsapDragCommit's five new-tween branches go through one newTweenTarget
helper; instant patches reuse the written target so the runtime moves the
element the source write names.
- useGestureCommit and useAnimatedPropertyCommit keep the existing selector
for matching/retargeting and author new tweens with a separate write
selector.
Retargets of an EXISTING tween are deliberately untouched: they keep
anim.targetSelector, so a tween aimed at a whole group stays aimed at it.
Narrowing the write alone regressed idempotency, verified by test: the
"is there already a write for this element" lookups matched targetSelector
by string, so the next nudge missed the write it had just made and appended
a second, conflicting one. The read half now falls back to the live DOM
(tweenTargetsElement, same contract as getAnimationsForElement), which also
still matches a deliberate group tween.
Tests reproduce each site through a real writer, re-parse with the real
parser, and resolve through resolveSelectorElementIds (what feeds the
keyframe cache and the lanes), plus pins for the new-tween vs
retarget-existing distinction so a future change cannot collapse the two.
Two latent defects in the announcement path this branch adds.
- lanesId was keyed by render row alone, so a second TimelineLanes on the
page (a mini-timeline beside the main one) would mint the same
timeline-lanes-track-0 and every caret's aria-controls would resolve to
whichever instance mounted first. The prefix now comes from useId, with the
colons stripped so the id stays a legal CSS selector.
- trackDisplayNumber returned trackOrder.length + 1 for a key it could not
find, which is indistinguishable from a real row: the label announced a row
the user can see is wrong and nothing upstream could tell it had guessed. It
returns null now, and trackDisplaySuffix drops the number from the label
rather than inventing one.
writeTargetSelector returned the selection's bare selector whenever the
structural walk failed, including when a live DOM was there to check
against. An element detached between selecting and committing takes that
path, so the add re-authored the exact `.group` string the function exists
to replace. Return null instead: a failed walk against a live DOM is
evidence, not absence of it. Callers that cannot drop a user edit opt back
in with `?? selectorFromSelection` where the trade is visible.
The replace-with-keyframes paths had the mirror defect. The server deletes
and re-adds the tween, so their target string is a full rewrite, and they
derived it from the selection: promoting a set on a tween already narrowed
to `#scene > div:nth-child(3)` widened it back onto every class sibling,
undoing the narrowing an earlier add had made. They now keep the tween's
own authored target, matching what eight sibling commit modules already do.
The timeline track key is a fractional z-order sort key: an expanded
sub-composition child gets `host.track + n / (siblings + 2)`. The undo
history entry for the eye toggle interpolated that key directly, so
hiding an expanded child recorded "Hide track 0.16666666666666666".
Give the key-to-display-row conversion a single owner
(timelineTrackDisplay.ts) and route both the track header labels and the
history label through it, so the two cannot drift apart again. The raw
key still routes the callbacks and lookups that need it.
Adds a regression test that toggles a track keyed 1 / 6; a test on track
0 formats cleanly and proves nothing.
"Add keyframe at playhead" on an element with no id authored the bare class
buildStableSelector hands back, so one add on a `.group` wrote
`tl.to(".group", ...)`: a tween that animates all five siblings and that
resolveSelectorElementIds reads back as all five, collapsing their timeline
rows into one. It survived a reload, so the written file stayed un-editable.
writeTargetSelector is the write-side counterpart to selectorFromSelection
(which must keep returning the exact string findTweenAtTime compares against).
It resolves the element's own identity to a selector that addresses exactly
one element: `#id`, else `[data-hf-id="..."]`, else the selection's selector
when it is already unique, else a `:nth-child` path anchored on the nearest
identifiable ancestor (the selector + selectorIndex pair, resolved through the
DOM the index was counted in).
Applied to the two paths that author a NEW tween: the no-animation branch of
useEnableKeyframes and commitKeyframeAtTimeImpl. replace-with-keyframes still
writes the selection's own selector, since retargeting a tween the author
aimed at a whole group is a different decision from adding a keyframe.
The timeline's track key is a fractional z-order sort value, and the header
built its visibility label straight from it, so screen readers announced
"Hide track 0.16666666666666666". A track's 1-based display row is now passed
alongside the key: the row number goes in every label, the key keeps routing
every callback (visibility toggle, lane context menu). The same fix covers the
`Track N` fallback used when a track holds no labelled element.
The layer disclosure caret's aria-controls named a div in the sticky label
column. That subtree is not empty, it holds the per-lane keyframe controls, but
its children are all absolutely positioned so the div computes to 0x0, and the
diamonds the caret visibly reveals live on the canvas instead. The caret expands
two disjoint subtrees and was naming the less useful one. TimelinePropertyLanes
now renders one static wrapper (static, not relative, so it establishes no
containing block and the absolutely-positioned lanes keep resolving against the
track-content div with identical geometry) and takes the id. TimelineLanes mints
that id, since it is the only place that sees both ends of the disclosure, and
mounts the wrapper for the track's keyframe clip in both disclosure states so
the reference still resolves while collapsed.
TimelineLaneBaseProps moves to its own module: it is the contract shared by
TimelineCanvas and TimelineLanes, and lifting it out keeps TimelineLanes.tsx
well under the 600-line cap instead of pushing past it.
animIdForProp matched on the parser's whole-tween propertyGroup, which is
undefined for a legacy mixed tween such as {x, opacity}. Such a tween never
matched, so an edit to either property fell through to the selection's
default animation, a different tween than the lane the user is editing.
Resolve through animationLaneGroups, the same per-keyframe helper the
rendered lanes and the reserved row heights already count groups with.
Two halves of one inversion in the expanded timeline lanes: the tweens
that should show were filtered out, and a tween that should not be there
was the only survivor.
Lane classification read the parser's whole-tween verdict, which is
undefined for anything spanning more than one property group. `{x,
opacity}` is the canonical HyperFrames entrance tween, so five of the
seven tweens in the swiss-grid graphics example had no caret, no
reserved row and no diamonds. Classify per property instead, through one
helper both the rendered lanes and the reserved row heights count
through so they cannot drift again.
Attribution matched an unanchored leading id, so `#stat3 .block` was
filed under `#stat3`. The child's diamonds landed on its ancestor and
collided with the ancestor's own tween at the shared percentage, which
the same-percentage merge then resolved by dropping the ease. Route
attribution through resolveSelectorElementIds, which anchors a
whole-selector id and otherwise resolves through the live preview DOM,
and anchor its no-DOM fallback so a descendant selector resolves to
nothing rather than to its ancestor. The merge rule is unchanged.
Also brings the last property-lane call site onto the shared clip timing
basis: an expanded sub-composition child's start is host-absolute while
its tweens are local to its own file.
Drilling two levels deep spared only the top-level row, so the middle host
lost its row and its keyframe lane with it. Spare every host between the
drilled one and the top, and anchor the children under the deepest host that
actually has a row.
Also stops resolveClipTimingBasis handing back a main-timeline start when a
clip names a parent composition that is absent from the element list. The
mount is unknowable there, so the child's own window is the only safe frame.
The sub-composition drill-in replaced the host row with its children. Since
expansion is also driven by the playhead alone (paused auto-expand), an
ordinary seek into a sub-composition made the host row disappear, taking its
keyframe lane with it: diamonds render per row from keyframeCache.get(
elementKey), so no row means no diamonds. Reproduced live with no drag at
all, seek 0 gave 3 diamonds, seek 7.68 gave 0, seek 0.2 gave 3.
Make the expansion additive instead. The host row stays and its children are
appended directly below it. The synthetic fractional lanes already used for
children sit strictly between the host's lane and the next integer, so the
host keeps its own row without colliding with anything.
The time-keyed auto-expand itself is unchanged.
buildExpandedElements synthesized DOM-only sub-composition children against
the top-level element rather than the parentHost it resolves immediately
after. Under two-level nesting every child row therefore inherited the
top-level window instead of its own host's, so the rows drew at the wrong
offset and duration.
A sub-composition tween's resolvedStart is composition-local, while the timeline
element resolved for it is the sub-comp HOST, whose start is main-timeline
absolute. toClipPercentage subtracted the two frames from each other, so a host
mounted at 1.5s cached its 0s tween at -12% and its last tween's end keyframe at
88% instead of 100%. A clip-relative percentage can never be negative.
resolveClipTimingBasis now returns the clip start in the frame the tween's own
times are measured in: the composition mount (expandedParentStart for an
expanded child, the parent composition clip's start otherwise, 0 for a
root-composition element) is subtracted, and a sub-comp inner element that falls
back to its host's window starts at 0 in that window. It moves to gsapShared so
the post-commit cache writer can share it instead of resolving its own basis,
which also gives that writer the sub-comp host fallback it was missing.
The gesture resolver gated on six digits while parseCssColor accepts both
lengths, so #F00 previewed as nothing and committed nothing. The old onBlur
path parsed it, making this a behavioural loss rather than a pre-existing gap.
Also asserts that an incomplete hex is restored on outside-click, not merely
left uncommitted.
The panel does not trap focus and leaves the rest of the editor operable,
so aria-modal would tell assistive tech the whole app is inert while it is
open. role=dialog plus aria-controls and Escape is the correct non-modal
disclosure shape.
Swap the panel's hand-rolled bubble-phase mousedown listener for the
shared useContextMenuDismiss hook, which adds Escape support and fixes
outside-click dismissal when a canvas gesture (e.g. marquee start)
calls preventDefault on pointerdown, which otherwise suppresses the
mousedown compat event entirely. Also wires up dialog ARIA (role,
aria-modal, id/aria-controls) between the trigger and panel.
Split hex-draft ownership so the hex input is the sole author of its
own text while editing (updateColorDraft no longer stamps a canonical
hex back over every keystroke), fixing snap-back on backspace and the
silent wrong-colour clobber on non-repeating hex values. Route hex
typing through the shared gesture transaction so outside-click and
Escape settle/cancel it like the other inspector fields, instead of
relying on a private onBlur commit that never fires once the panel
unmounts on outside-click.
The 24x24 WCAG 2.5.8 overlay sits on a wrapper that outranks the diamonds,
so on a segment narrower than 24px it overhung them and won their hit test at
fit zoom. Gate the overlay on the clear span between the two diamonds and let
the button keep its 16x16 box below that.
Also renames the pointer target suite to say it asserts the classes that
produce the size, not the measured geometry, which happy-dom cannot see.
A ruler press with no pointer movement settled the playhead at t=0 instead
of the clicked time. handlePointerUp replays pendingClientXRef, which only
the pointermove path wrote, so a plain click fell back to the ref's initial
0 and overwrote the correct pointerdown seek. Seed the ref on pointerdown.
The keyframe retime move branch also returned the raw quotient while the
resize branch rounded to 3dp, so values like 74.81203007518799% landed in
the user's source and churned the diff on every drag. Round at the point of
computation so the no-op test and the written value agree.
* fix(cli): persist authoring skill in hyperframes.json for durable render attribution
authoring_skill was stamped only on the first render through a workflow
passing --skill, so re-renders, `npm run render`, --batch, existing-project
renders, and general-video lost it — leaving 77-96% of real-human render
volume un-attributed and the skills-penetration metric misleadingly low.
Persist the owning skill in hyperframes.json: `init --skill` stamps it at
creation, `render` resolves the flag then falls back to the stored value, and
an explicit --skill seeds it (seed-once, never overwriting the creating
workflow's identity). Activate all render-producing creation workflows to
declare their skill at init.
Forward-only: does not rewrite historical telemetry.
* fix(cli): patch hyperframes.json in place when seeding the authoring skill
seedProjectAuthoringSkill is the only writer that touches an already existing
hyperframes.json — every other writeProjectConfig call site is guarded to write
only when the file is absent, which made the whole-file overwrite safe by
construction. Round-tripping the seed through normalizeConfig broke that: it
rebuilds the object from a field whitelist with no rest-spread, so any key
outside the schema was silently dropped, a media block was materialized in
projects that never had one, and key order was rewritten. hyperframes.json is
normally committed, so a render introduced a diff the user never asked for, and
any field added to the schema later would be deleted by a render on an older
CLI.
Parse the raw JSON, set authoringSkill, write it back, reusing the file's own
indentation. Unknown keys and formatting survive; the only delta is the key
being added. A corrupt config is now left untouched instead of clobbered.
Seed-once semantics are unchanged, still normalized so a hand-edited garbage
slug neither reaches telemetry nor wedges the seed.
Reported independently by both reviewers on #2762.
* fix(cli): create the docker build context with mkdtempSync
The `--docker` build context was created at a guessable path derived from
`Date.now()` in the world-writable OS temp dir. Another local user can
pre-create or symlink that path and have the build read a Dockerfile they
control. mkdtempSync gets a random suffix and 0o700 from the kernel, and it
creates the directory itself, so the separate mkdirSync goes away.
Pre-existing on main (alert #432, 2026-06-04, packages/cli/src/commands/render.ts),
surfaced against this branch only because the seed commit shifted line numbers in
the same file. Fixed here to unblock the CodeQL gate on #2762 rather than left for
a follow-up; the remaining 10 js/insecure-temporary-file alerts elsewhere in the
repo are untouched and still want their own pass.
* fix(cli): drop the check-then-use race when seeding the authoring skill
The seed tested for the config with existsSync and then wrote, which is a
check-then-use race: the file can be created or swapped between the check and
the write (CodeQL js/file-system-race).
Read once and branch on the failure reason instead. Only ENOENT creates a
config from scratch; any other read failure (permissions, I/O) now leaves an
existing file alone rather than overwriting it with a default, so this is also
strictly safer than the version it replaces.
Also replaces the `as Record<string, unknown>` assertion with an isJsonObject
type guard, per the repo's no-assertion convention.
Behaviour unchanged: all 4 seed regression tests still pass, and the
create/preserve/seed-once/corrupt-untouched paths were re-verified end to end.
trackRenderComplete requires `gpu: boolean`; the two new opt-out test
calls omitted it, failing Typecheck in CI. The fix already existed on the
stacked branch, so only this base branch was broken.
