fix(producer): degrade gracefully when font cache directory is unwritable (#3572)
* fix(producer): degrade gracefully when font cache directory is unwritable When the font cache root (~/.cache/hyperframes/fonts/) cannot be created (EPERM on read-only filesystems, restricted home directories, etc.), the render aborts with a raw mkdir error. The cache is an optimization, not a requirement — a missing cache should mean slower first renders, not broken renders. Fall back to a temporary directory under os.tmpdir() when the configured cache root fails, so Google Fonts downloads still proceed. The fallback cache is per-process and not persistent across renders, but the render completes. Fixes #3412. * fix: use mkdtempSync for font cache fallback, restore warning Rames Jusso's review caught a regression in the force-push: the predictable tmpdir path is unsafe (symlink attacks in world-writable dirs), and the warning log was dropped. Restore the mkdtempSync pattern matching lambdaFontCacheRoot, add a CLI hint per Miguel's request, and reuse the ephemeral root across calls. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: emit font cache fallback warning once per run, not per font Gate the warning on whether this is the first fallback activation. The ??= already suppresses repeat mkdtempSync, but the warn fired for every font family in the composition.

fix(cli): pick the highest-quality favicon and keep its transparent background (#3606)
* fix(cli): capture the best declared favicon, not the first one
Pages routinely declare a legacy 16px .ico first and the good asset (an SVG,
or a 180x180 apple-touch PNG) after it. The capture's page evaluate kept only
{rel, href} and the download loop took whichever candidate fetched first, so
the .ico won on every such page. The dropped sizes/type attributes are the only
evidence of quality: page.html on disk does not keep the <link> tags and only
the winner's bytes are fetched, so the choice was unrecoverable downstream.
Keep sizes and type, and rank candidates before downloading: SVG first, then
the largest declared size (an unsized apple-touch-icon counts as 180), then
.ico. The loop still falls through to the next candidate when one fails to
download, so the ranking changes which icon wins, never whether one lands.
Ranking is a pure function over the declared attributes, unit-tested against
the link shapes three sites actually publish.
* fix(cli): rank a pinned-tab mask-icon below real favicons
`link[rel*="icon"]` also matches `rel="mask-icon"`, Safari's pinned-tab
asset: a single-colour silhouette drawn in a browser-chosen tint, not the
site mark. It is served as an SVG, so ranking by format alone promoted the
outline above the page's actual colour favicon.
Give mask-icon its own lowest tier rather than dropping it, so a page that
declares nothing else still lands an icon instead of none.

feat(cli): capture reports why a referenced asset is not in the folder (#3598)
Capture drops assets for four reasons and reported none of them, so a folder
with thirty images and a folder truncated to thirty images were the same
object. Every drop site was a bare `continue`, `break`, `return null` or an
empty `catch`, and the only signals downstream were two hand-written warning
strings that fired when the budget was already gone before a download pass
started, which is the one case where the pass could not say how much it lost.
`downloadAssets` and `downloadAndRewriteFonts` now return an `AssetDropCounts`
tally beside their result, incremented at the single line that performs each
drop. `capture --json` carries it as `dropped`; the human summary prints a
`Dropped:` line when it is non-zero.
Four reasons, three decisions and one failure:
size-floor fetched, then judged too small to be a real asset
budget-exhausted the post-navigation clock ran out before this one
cap-reached 30 inline SVGs, 30 fonts, or 6 faces per family
unavailable the request or the write failed
A break now counts everything it did not reach rather than the one it stopped
on, because "how many did we lose" is the question and one is never the answer.
The two budget warnings are gone. Both existed only to cover the case where
the budget ran out before a pass was called, so both passes are now called
unconditionally: a zero budget makes each loop break on its first item and
record `budget-exhausted` for the rest, which costs no network and produces a
real number instead of the word "some". The single remaining warning is derived
from the tally, so the prose and the count cannot disagree.
Measured on a live capture of a large marketing site:
default budget 232 kept, 91 dropped (39 size-floor, 20 cap-reached,
32 unavailable)
15s budget 30 kept, 299 dropped (279 budget-exhausted, 20 cap-reached)
Same page, same command, and until now both runs described themselves the same
way.

test(engine): give the 150-track audio mix test a Windows-sized budget (#3587)
The ENAMETOOLONG regression writes 150 real clip files and the mixer existence-checks each one: ~58ms on Linux, but past vitest's 5s default on the Windows lane. packages/engine sets no global testTimeout, so heavy tests here carry an explicit one. On timeout its abandoned async work kept calling the shared runFfmpegMock after afterEach cleared it, so the next test saw 5 calls instead of 3 and lost its queued once-implementations to the leak. mockReset stops an aborted test from handing leftovers to the next one. |

feat(registry): say what a promoted template's slots mean, not where they sit (#3562)
* feat(registry): say what a promoted template's slots mean, not where they sit
Every declaration described its slot by position — appName was "small credit in the corner
of every banner" — and every editing contract described the supplied brand only by what it
may not touch, chatgpt-exchange going as far as "only the subject discussed inside the
conversation". An agent filling those slots has nothing telling it that the video is an
advertisement for that brand, and remixes shipped with an invented brand instead of the
real one.
Adds `portrays` to the 35 identity-bearing variables across seven templates: what the slot
stands for, as a list, kept orthogonal to `role` (which says which aspect of the
composition a knob affects, not what a value means to a viewer). Rewrites those variables'
descriptions to state meaning, and gives every TEMPLATE.md the affirmative sentence it was
missing. notes-reveal now records honestly that it declares no identity slot at all, which
is why a remix of it cannot carry a brand.
`portrays` is optional metadata: rendering ignores it, the promoted contract still projects
{id, type, role}, and packages that predate it keep working. Variable ids, types, roles,
labels, and defaults are untouched, so installs and renders see the same contract.
* feat(notes-reveal): give the template somewhere to say whose ad it is
This was the one promoted template that declared no identity slot at all, and the
previous commit could only record that honestly. A remix of it could not name the
advertiser, could not carry its domain, and had nowhere to place its mark — so the
ad it produced was unattributable no matter how good the copy was.
The closing card ends at y=1708, leaving 212px of dotted scene. A sign-off strip
lives there: `brandLogo` (portrays subject_logo) above `brandDomain` (portrays
subject_domain), in the card's own plum and Courier Prime. Putting it outside the
card means the hand-lettered headline and the checklist keep the geometry they were
designed with — verified by `hyperframes check`, which reports the same 0 errors and
the same warning counts as origin/main, with one more contrast check (367/367 AA).
No name slot: this template has no text slot that can hold a bare brand name.
`cardTop`'s marker line continues into the fixed words "OF ONE FILE", and a name set
beside a wordmark reads twice — rendering it proved that before this was committed.
The mark plus the domain carry the attribution, which is what the other end-card
templates do.
Rendered to check rather than assumed: the packaged default reads as the HyperFrames
wordmark over hyperframes.heygen.com, and a resolved symbol mark (Notion's cube over
notion.com) sits correctly in the same strip.
* fix(notes-reveal): make the note the ad, and stop the headline leaving the card
Three defects, all visible in the reported gamma remix.
The seven body lines carried their characters as pre-split `<span class="ch">`
elements so the reveal animation could address them by id. That made the note
permanently unwritable: 46% of the 24.9s runtime, and the only place the note
says anything, was fixed copy about making videos with HyperFrames -- shipped
inside an advertisement for a Dutch DIY chain. The spans are now built at
runtime from seven declared variables, keeping the same ids, so the animation
is untouched and the copy is the brand's.
`cardMid` and `cardBottom` ("OF", "ONE FILE") were literals with no variable at
all, so a remix could only ever change the first of the card's three lines.
Every text slot sat at a fixed left edge on one line, guarded only by a
character cap -- the wrong unit. `cardTop` allowed 12 characters; "THE POWER"
(9) fits and "CREATE DECKS" (12) does not, which is why both reported gamma
remixes shipped with the closing headline over the edge of the card. Slots are
now fitted to their box at render time, shrinking type only as far as needed and
never past the designed size. The card headlines also carried
`data-layout-allow-overflow`, switching off the one check that would have caught
it; those waivers are gone. The note's title and body keep theirs, because
`#note-body` is translated across the whole scene and leaves the canvas by
design.
Timing is preserved rather than regenerated: each body line is revealed inside
the frame window the packaged rhythm already used, so `JUMPS` and the hand-tuned
`SCROLLS` curves stay valid and the composition is still 24.867s for any length
of copy. A line whose length matches the packaged copy keeps its rhythm frame
for frame.
Verified: rendered with the packaged defaults, SSIM 1.000000 across all 746
frames against the previous template -- the design is bit-identical. Rendered
with the gamma values that overflowed, and with a stress set of long and
one-word values: both stay inside the card and the note, both still 24.867s.
`hyperframes check` passes, with layout warnings down from 28 to 8 and no new
issue class. Note that `check` takes no variable values, so it guards the
template's defaults and the fit is what guards a remix.
* fix(notes-reveal): make the fit floor and the character caps agree
A cap that admits a string still too wide at the floor font size puts the text
back outside its box -- the exact bug the fit was added for. With the floor at
0.6 and the title cap at 40, a 40-character title still overflowed `#note-body`
by 30px, because "Things nobody told me" is 21 characters and 900px at 88px, so
42.9px per character, and 40 characters need to reach about 0.45 of the design
size to fit.
Floor to 0.45 and the caps in: titles 34, body lines 52, cardTop and cardBottom
16. Every cap is now satisfiable with room to spare, and the common case stays
far from the floor.
Found by probing all eight promoted templates with values about 1.8x the length
of their packaged defaults, which is the length a real remix produces; short
sentinel values only ever prove a slot is wired.
Defaults are unaffected: SSIM 1.000000 across all 746 frames, still 24.867s,
`hyperframes check` still passes.
* fix(exchange): scroll the composer to follow the caret
`prompt` is an editable slot in both templates, but `.comp-text` is a
fixed-width single line with `white-space: pre` inside a composer that clips,
and the packaged prompt already reaches the mic -- it has no headroom at all.
A longer prompt therefore slid under the mic and the send button and lost its
tail, with the caret hidden behind them: the remix read as having typed into
nowhere, cut mid-word.
Both now scroll the typed text left to keep the caret in view, the way a real
single-line input does, on the very per-character times the reveal already uses.
The limit is measured to the opaque round button rather than the mic, because the
packaged prompt's caret already sits 2px past the mic's left edge in
chatgpt-exchange -- measuring to the mic would scroll the packaged composition.
Shrink-to-fit was the other option and it is worse: with no headroom it shrinks
the packaged prompt too, and it still cannot absorb a prompt twice as long
without unreadable type. It was tried, measured, and dropped.
A prompt that fits emits no keyframes and the element is never handed to GSAP at
all -- even a zero translate stamps a transform, which changes how the text
rasterizes.
claude-exchange puts this inside its existing `build()`, which already re-runs on
`document.fonts.ready`, so it measures the final font. chatgpt-exchange builds
once, so its scroll keyframes are kept in a list and rebuilt on the same event.
Verified on the packaged defaults: claude-exchange SSIM 1.000000 across 1284
frames. chatgpt-exchange is not frame-deterministic -- rendering it twice
unchanged gives 0.999959 with 249 frames under 0.9999, and before-vs-after gives
0.999967 with the same 249 -- so the change sits inside its own noise. Durations
unchanged at 14.9s and 21.4s. `hyperframes check` reports byte-identical results
to the unchanged templates.
* fix(notes-reveal): fit the checklist cells instead of counting their characters
The three checklist rows were the only text slots with no width fit, so
their character cap was doing the job a measurement should: it was set to 8
because that was the widest the packaged strings needed, and a gamma.com
remix delivered "DIRECT MEE" and rendered "DIRECT M".
Fit the labels and values like every other text slot -- dividing the
label's scaleX(0.86) back out of its column, since fitWidth measures the
untransformed width -- and return the cap to a backstop at 18.
"DIRECT MEE" needs no shrink at all: it ends at x=694 against a tick at
x=715, so the truncation was never about room. Measured: the packaged
defaults still render at their authored 44px and 50px, and all three values
clear the tick.
* fix(chatgpt-exchange): nest the caret scroll so its rebuild can be undone
`tl.to()` returns the TIMELINE, not the tween it created, so `caretScrollTweens`
held 49 references to the master timeline. The fonts-ready rebuild then called
`.kill()` on the master timeline 49 times and re-added its keyframes on top of
the ones it meant to replace. Measured with an overflowing prompt:
master timeline detached from the global timeline (tl.parent -> null)
scroll tweens on #cge-typed: 49 before the rebuild, 98 after
49 timestamps left with two competing tweens on the same property
GSAP's `Animation.kill()` interrupts and detaches rather than killing children,
so the composition kept rendering under an explicit seek -- which is why the
packaged-defaults SSIM check passed and never saw this. It is still wrong: the
timeline is off the ticker, and the stale keyframes were measured against the
fallback font.
Only an overflowing prompt reaches it, i.e. exactly the remix the scroll exists
for. The packaged prompt emits no steps, so nothing is created and nothing is
killed.
Now one nested child timeline holds the steps: a real object that can be killed
and replaced, and killing it cannot reach `tl`. Children sit at the same absolute
times and the nest is added at 0, so the motion is unchanged.
Verified: overflowing prompt holds at 49 scroll tweens across the rebuild with no
duplicated timestamps and the timeline stays attached. Packaged defaults against
the pre-feature baseline -- SSIM 0.999998 over 894 frames, 13 frames below
0.9999 against a 249-frame noise floor for this template, duration 14.9s
unchanged.
Found by Magi in review of #3562.

* feat(lint): catch a timeline's return value being treated as a tween
Magi asked for a regression that makes the caret-scroll failure unable to return.
A render fixture cannot be that guard, and neither can a unit test. Both were
measured before choosing this:
- The unit-test DOM has no layout. In happy-dom `getBoundingClientRect()` is
{left: 0, width: 0} and offsetWidth/offsetLeft are 0, so the template's own
guard computes limit = -8 and returns before collecting a single keyframe,
whatever the prompt length. `document.fonts` does not exist there either, so
the rebuild never runs. Both preconditions are unreachable -- the test would
pass on the broken code and the fixed code alike. Rames flagged this; verified.
- A render fixture would not fail either. Rendering the long prompt through the
real pipeline on the broken vs fixed template gives SSIM 0.999994 over 894
frames with ZERO frames below 0.999. The renderer drives the composition by
explicit seek, and the duplicated keyframes are added last so they win, which
is exactly why `.kill()` on the master timeline stayed invisible. A golden mp4
would have cost a fixture and a shard and guarded nothing.
What is testable is the root cause, and it is a static property: `tl.to()` returns
the TIMELINE, `gsap.to()` returns a Tween, and the two read identically. So the
guard is a lint rule, which needs no DOM, fires on the source, and covers every
composition in the registry rather than this one template.
The rule keys on the timeline handles `collectTimelineVarNames` already finds,
which is what keeps `gsap.to()` and `Array.from()` out of it. Pushing a timeline
return into an array is flagged outright -- that is the collect-to-discard shape.
A bound return is flagged only once something tween-scoped is aimed at it, so a
pointless-but-harmless capture stays quiet.
Verified against the real files, not just synthetic ones: the pre-fix
chatgpt-exchange raises exactly one error and names the offending line; the fixed
file is clean. Across all 642 HTML files under registry/ and examples/ the rule
finds nothing, and lint output on the eight promoted blocks is identical to
origin/main error-for-error and warning-for-warning, so error severity costs no
existing template. 540 lint tests pass, 6 of them new.
Requested by Magi in review of #3562; unit-test DOM measurement by Rames Jusso.

fix(capture): let vision captioning authenticate the way a server can (#3561)
* fix(capture): let vision captioning authenticate the way a server can Three defects in one phase, all of which end with a capture that reports "Captioned N/N images" and then "0 images captioned with Gemini" — a successful-looking run that hands the agent nothing to see by. 1. Credential. The captioner only accepted an API key. A server deployment holds a service account, not a key, and a rejected key is indistinguishable from an unset one here: every request returns empty text and no error. Vertex is now a first-class provider, ranked above the bare key and below an explicit OPENROUTER_API_KEY opt-in, configured by HYPERFRAMES_VERTEX_SERVICE_ACCOUNT + HYPERFRAMES_VERTEX_PROJECT_ID (region via HYPERFRAMES_VERTEX_LOCATION). It carries its own model default because the Gemini API's flash-lite preview id is not resolvable on Vertex. 2. Empty captions. Thinking tokens are drawn from maxOutputTokens, so a model left free to think can spend the whole budget and return no text — a successful request with no caption. thinkingBudget is pinned to 0; a one-line factual caption needs no reasoning. 3. Native abort. Rasterizing a batch of SVGs concurrently drove up to SVG_BATCH simultaneous librsvg renders through libvips and corrupted the heap: `free(): unaligned chunk detected in tcache 2` (SIGABRT) during this phase, twice in fourteen days, losing the whole capture each time. A native abort cannot be caught, so the concurrency is removed rather than handled — rasterization is serialized and libvips' worker pool is bounded, while the vision requests, which are the slow leg, stay parallel. Throughput barely moves: 225 captions across three real captures, 0 failures, 13-25s each. * test(capture): pin the rasterization loop to one render at a time The serialization fix shipped without a regression test on the grounds that native heap corruption is not unit-testable. The corruption is not, but the property that prevents it is: `sharp` is mocked to record how many renders are in flight, and a six-SVG batch must never reach two. A deliberately slow caption stub makes overlapping renders the faster path, so a future refactor that "optimises" the loop back to `Promise.all` fails here instead of aborting in production. Also covered: `sharp.concurrency(1)` is applied — serializing the loop while leaving libvips' pool at the host core count still fans one render across every core — and an unrasterizable SVG is skipped without breaking serialization for its siblings. Verified as a real guard: reverting only contentExtractor.ts to origin/main fails 7 of the 22 cases in this file. * fix(capture): tell the truth in the asset-descriptions header when Vertex captioned The provider gate in `contentExtractor` accepts Vertex when a project and a service account are both set -- which is the configuration a server deployment actually has. The header written next to the captions still tested only for an API key, so a capture whose captions Vertex had just generated was labelled "GEMINI_API_KEY not set -- descriptions below are catalog-derived". That header is not cosmetic: it travels into the context the template editor reads, telling it to distrust captions that are real. Mirror the same two variables here, and name every provider in the fallback text instead of only the API key. * fix(capture): hand libvips' worker pool back after the renders `sharp.concurrency(1)` is process-global and was set once, for the whole life of the process. The bound is right for the rasterize loop -- a native abort in libvips cannot be caught, so the renders must not overlap -- but its scope was every later sharp caller in the process, none of which asked for captioning, all of them pinned to one thread from then on. Now the host's value is read first and restored in a `finally` around the rasterize loop, so a skipped SVG cannot cost the process its threads either. The vision requests below are network work and gain nothing from a pinned pool. The mock had to grow the getter half of sharp's API -- `concurrency()` with no argument reports the current value -- since save-and-restore is untestable without it. Verified as a real guard: dropping only the restore fails both new cases. Raised by Rames Jusso in review of #3561 and concurred by Magi. |

fix(cli): guard PowerShell process queries against exited PIDs (#3571)
## Summary
`processIdentity` and `processParentPid` call `Get-CimInstance Win32_Process` to look up process metadata on Windows. When the target process has already exited, `Get-CimInstance` returns null and calling `.CreationDate.ToFileTimeUtc()` or `.ParentProcessId` on it throws `InvokeMethodOnNull`. The try/catch handles it, but PowerShell writes the error to stderr, which pollutes the test runner's output and causes spurious exit code 1 on Windows CI.
Two fixes per call site:
- Null-check the CimInstance before accessing properties (`$p = ...; if ($p) { $p.Property }`)
- `-ErrorAction SilentlyContinue` + `stdio: ["pipe", "pipe", "ignore"]` to suppress any residual stderr
Fixes the recurring `Tests on windows-latest` flake on main.
## Test plan
- [x] All 196 CLI test files pass locally
- [ ] Windows CI should no longer exit 1 from PowerShell stderr noise

feat(studio): let an agent author motion (#3520)
* feat(studio): let an agent drive Studio's selection and playhead
Adds `studio_select` and `studio_seek`, so an agent and the human are looking
at the same element and the same instant. Selecting reveals the inspector,
exactly as a click does, which is what makes the agent's move visible.
Selection is shared state, not a per-call argument, and that is forced rather
than chosen. Most of Studio's edit handlers read the ambient React selection,
and `applyDomSelection` only schedules a state update, so selecting and
committing inside ONE call would write to whatever was selected before. Two
tool calls are separated by a render, so the contract is select first, then
act. That is also how a human works: click, then type.
`studio_seek` uses `requestSeek`, not `setCurrentTime`. The latter only moves
the timeline's displayed number and leaves the composition where it was.
Two things the tools refuse to fake:
Seek does not clamp. `seek()` already clamps against the adapter's duration,
which can differ from the store's, and clamping again would give that
invariant two owners that can disagree. The tool reports where the playhead
actually landed instead, read back afterwards.
`requestSeek` is fire-and-forget, so it cannot report that no adapter was
mounted to receive it. The tool compares the playhead before and after and
fails rather than claiming a seek that never happened.
Select separates three failures that a single message would have merged: the
preview is not mounted yet (wait), no element matches the handle (re-read),
and the element cannot be selected (try a neighbour). The agent's next move
differs for each, so collapsing them would cost it a round trip or a retry
loop.
* feat(studio): give an agent eyes with studio_frame
Renders the composition to a PNG at a given time and returns the URL. This is
what turns the tool set from a remote control into a loop: author a change,
capture the instant it affects, look, adjust. No agent can judge motion from
source, because "what does this look like at 2.4 seconds" is not a question a
file answers.
Reuses Studio's existing capture endpoint via `buildFrameCaptureUrl` rather
than inventing a second one.
Two things this does not fake:
It reports the time the playhead LANDED on, not the time requested. The player
clamps, so those differ at the ends, and attaching the wrong time to a frame is
how an agent draws a confident wrong conclusion about motion.
It waits before capturing, by default 150ms. The frame is rendered from the
file on disk, and the render cache is cleared by a file watcher with a 40ms
write-stability threshold, so a capture that beats the watcher renders the
PRE-edit composition. That exact staleness was a real bug here once. An agent
reading a stale frame as "my edit failed" would thrash, so the wait is on by
default, `settleMs` makes it tunable, and the tool description names the
failure rather than leaving it to be rediscovered.
It probes with HEAD before returning, so a URL that 404s comes back as a
failure with a hint instead of as a link the agent cannot render.
* feat(studio): add studio_inspect, so an agent reads before it writes
Everything about one element in one call: resolved styles, text fields, box,
data attributes, GSAP animations, and what the element will and will not
accept.
The point is to prevent a failed write rather than to satisfy curiosity.
`can.reasonIfDisabled` is passed through verbatim from Studio's own
capabilities, so an agent that reads first should never attempt an edit the
element would refuse.
Three things it refuses to get wrong:
Animations are reported ONLY for the current selection, because that is the
only element Studio parses them for. Attributing them to any other element
would be reporting the wrong element's motion, which is worse than reporting
none. When a handle names something else the field is empty and
`animationEditingBlocked` says why.
`animationEditingBlocked` also carries the two states where animation editing
is off entirely, multiple timelines and an unsupported timeline pattern. Both
live on the selection context. Learning them from a read costs one call;
learning them from a failed write costs a retry loop.
Inspecting a handle does NOT change what is selected. It is a read, and
stealing the human's selection would be a side effect they did not ask for.
There is a test asserting `applySelection` is never called.
Nothing selected and no handle given is a failure, not an empty result. An
empty result would assert "this element has nothing", which is a different and
false claim.
* feat(studio): let an agent edit text and styles, guarded
The first tools that change the composition. Both act on the current
selection and take no handle, which is forced rather than chosen: the
handlers read the ambient React selection, and `applyDomSelection` only
schedules a state update, so selecting and committing inside one call would
write to whatever was selected before. Select first, then edit.
Also plumbs the write-blocked state, which was the blocker for shipping any
write at all. `domEditSaveQueuePaused` and the external-file conflict both
lived on App and were unreachable from the tool surface, so `canWrite` was
optimistic and a comment said so. They now derive into a single
`writeBlockedReason` on the shell context: one field, one owner, conflict
taking precedence because resolving it is what unblocks the queue.
That guard matters more than it looks. Both states are BANNERS in Studio with
no lock behind them, so nothing else was stopping a programmatic write from
landing on top of a conflict the user had been asked to adjudicate.
Three things the tools refuse to fake:
They check the outcome, not the absence of a throw. Studio has several paths
where a failed commit resolves anyway, so awaiting the handler proves nothing.
The tagged outcome added earlier is what proves the write landed.
A partial style result is reported as partial. `handleDomStyleCommit` is one
property per call, so N properties are N commits; the result carries `applied`
and `rejected` maps rather than a single boolean that would have to pick a
side.
Style commits run sequentially, never concurrently. Two commits racing through
Studio's client-side read-modify-write can record undo entries that both claim
the same starting content. There is a test that measures concurrency rather
than trusting the loop.
Every decline reason maps to a hint naming what to do instead, so a refusal
routes the agent rather than just stopping it.
* feat(studio): move, resize and rotate, verified by reading back
`studio_transform` does what a drag does, and then checks. The box in the
result is READ BACK after the write, never echoed from the request, and
`applied` lists what actually took effect.
That is not belt-and-braces. The plan for this unit said to re-derive the
geometry handlers' behaviour rather than trust any description of them, and
doing that turned up three different behaviours behind one interface.
The handlers on `DomEditActionsValue` are the GSAP-AWARE wrappers, aliased in
`useDomEditSession.ts:534-538`, not the CSS ones in `useDomGeometryCommits.ts`
that an earlier note in this workstream described.
`handleGsapAwarePathOffsetCommit` and `handleGsapAwareRotationCommit` are
`if (gsapCommitMutation) { ...intercept... }` with no else branch. Their own
comments say the absence is deliberate: position and rotation are written as
GSAP code and there is no CSS fallback to write to. So they can return having
done nothing.
`handleGsapAwareBoxSizeCommit` is not like the other two. It runs through
`runGestureTransaction` with separate scale and width/height routes, so resize
works more generally.
Reading back is what turns that middle case from a silent lie into a reported
one. A move that did nothing comes back in `unchanged` with a reason.
Three smaller decisions:
Operations re-read between each other, so a move is judged against the box
AFTER a resize in the same call. Comparing against the original would credit
the resize's change to the move.
Rotation is reported as dispatched, not verified. `rotate` is an individual
transform property and does not appear in the computed transform, so there is
no honest box-derived signal, and claiming one would be worse than saying so.
x pairs with y and width pairs with height. Accepting one alone would mean
inventing the other from the current value, which moves the element somewhere
the caller did not ask for. The pairing rule and its minimum live in one
`parsePair` helper rather than as four separate branches.
* feat(studio): let an agent author motion
Four tools: add an animation, change its duration/ease/position, add a
keyframe, delete it. This is the capability that makes the tool set worth
having, because motion is the one thing an agent cannot judge or author from
source.
These are deliberately less confident than the rest of the set, and the
reason is the handlers underneath them:
`handleGsapAddAnimation(method)` takes only a method. Its insert position
comes from the live playhead, not the caller, and the call is `void ...catch()`
so it returns nothing.
`handleGsapAddKeyframeBatch` returns a promise but catches its own failure, so
awaiting proves the call finished, not that it landed.
`handleGsapDeleteAnimation` discards its promise entirely.
`handleGsapUpdateMeta` is the one honest signal. It returns a boolean.
U8 handled the same problem by reading the result back. That does not work
here: the animation list comes from React state that only refreshes on a
render, and no render happens inside one tool call. Rather than fake a
verification with a frame-timer, these report what was DISPATCHED and the
descriptions tell the agent to call studio_inspect to see the result. Saying
"I asked for this" is honest; saying "this happened" would not be.
Three consequences worth stating:
`studio_add_animation` takes no position. The handler reads the playhead, so
accepting one would report a number that had no effect. It reports where the
playhead actually was and tells the agent to seek first.
`studio_update_animation` rules out the no-selection case BEFORE dispatch. The
handler answers `false` for both "nothing selected" and "the write failed", so
eliminating one is what makes the other legible.
Keyframe percent and properties are validated in the tool, because nothing in
the platform checks input against the declared schema.

* docs: document Studio's WebMCP agent tools, proven end-to-end in a browser (#3521)
* docs: document Studio's WebMCP agent tools
Adds `guides/webmcp`, under Developers > Agent setup.
Its first job is to defuse a name collision. `guides/mcp` already exists and
covers HeyGen's HOSTED MCP connector, which builds a video from a chat. This
page is about an agent working inside Studio on a composition already open in
front of you. Different feature, confusingly similar name, so the page says
what it is not before it says what it is.
Written to DOCS_GUIDELINES: one-sentence intro, outcome before implementation,
real values rather than placeholders, and three callouts.
The three things a reader most needs are the ones easiest to get wrong:
The API is `document.modelContext`, not `navigator.modelContext`. Most
published examples use the second, which is a polyfill compatibility shim
rather than a spec member, so feature-detecting it misleads.
Select first, then edit. Most editing tools act on the current selection, and
an agent that skips it gets an error rather than a wrong-element write.
Leave Studio visible. Some of Studio's write paths report failure through a
toast rather than a return value, so the human is the one who sees it. That is
a real property of the co-pilot design, not a nicety, so the page says it
plainly.
Verified with `npx mint validate` and `npx mint broken-links --check-redirects`,
both passing.
* fix(studio): target the text field that exists, not one named self
Found by running the tools end to end in a browser, which is the only way it
could have been found: the unit tests mock `setText`, so they never crossed the
boundary where this breaks.
An element's text usually lives in a CHILD field, keyed like `self:0:h1` or
`child:0:h1`. `studio_set_text` passed no field key, so
`buildNextDomTextFields` planned zero operations, the request went out with an
empty patch, and the server answered:
POST /api/projects/<id>/file-mutations/patch-element
-> 400 {"error":"target and operations required"}
Which surfaced as `persist-failed`. The tool was telling the truth, so the
reporting work in the earlier PRs did its job, but the failure looked like a
server problem and was not.
The tool now resolves the field: the one the caller named, or the element's
single field when it has exactly one. An element with several fields is asked
to name one; an element with none is reported blocked. Naming a field the
element does not have is rejected with the list of the ones it does have,
rather than silently writing nowhere.
Four regression tests, including the exact `child:0:h1` shape that failed. One
existing assertion changed: it expected the field to be `undefined`, which is
precisely the bug, so it now expects the resolved key.
Also documents two things the browser run surfaced, both real and neither a
defect: registration is asynchronous, so a caller reading `getTools()` too
early sees a partial list; and the tools that act on the current selection need
a render between the select and the edit, which a real agent gets for free
because its calls arrive as separate messages.
* docs: give the agent-tools kill switch instructions that work
The page told readers to set agentToolsEnabled in Studio's preferences.
Nothing writes that flag: it is read in useStudioAgentTools and parsed in
studioUiPreferences, but there is no settings UI and no toggle, so the
instruction could not be followed. Replace it with the localStorage write
that actually flips it, and spell out the merge, since overwriting the key
drops every other stored preference.
* docs: do not promise a per-call permission prompt we have not verified
The page said the browser asks before any agent calls a tool. Prompt
granularity is browser-specific and unsettled during the origin trial, and
we have not observed it on the native path. Say what holds, that access is
gated, and name the part that is still moving.
* fix(studio): re-apply WebMCP test polyfill fix (#3532 regression)
The squash merge of #3518 re-introduced the old assertion that
document.modelContext is absent. The polyfill from #3514 installs it
as a fallback — that is expected behavior.
Same fix as #3532: remove the assertion, keep the boot-cleanly contract.

fix(studio-server): revalidate preview assets on every request (#3565)
Project preview assets (images, videos) were served with Cache-Control: private, max-age=3600, must-revalidate. The 1-hour max-age let browsers serve stale images from their disk cache without revalidating, even after the file changed on disk. Hard refresh didn't recover because it doesn't bypass iframe sub-resource caches. Switch to `no-cache` so browsers always revalidate against the existing mtime+size ETag. Unchanged assets still get efficient 304 responses. Fixes #3564 |

fix(studio): let a hidden sub-composition child be shown again (#3559)
The eye on an expanded sub-composition child always rendered as "Hide", whatever the source said. One click hid the element and every click after that rewrote the same attribute, so the row could never be shown again, not even after a reload, since data-hidden is in the file. buildChildElements synthesizes a child row from a manifest clip with no element to read, and compensated by inheriting hidden/timelineLocked/ timelineRole/fxChain/automation from the child's flat store twin. That twin does not exist for a real sub-composition: processTimelineMessage drops any clip whose parent composition is itself in the manifest before building the flat store, so the lookup always missed and the inheritance was dead code for the one case it was written for. It worked only for a phantom-wrapper parent, where the child does keep a store entry. Read the state off the live element instead. collectSubCompositionHostState walks each sub-composition host in the preview document and records the data-* state of every id'd descendant, keyed by dom id. The existing sibling walk cannot serve this: it defines which rows exist and writes parentMap, and it stops at the first id'd descendant, so scene footage sitting one level below an id'd region wrapper is never reached. The new walk descends the whole subtree and touches neither rows nor parentage. Reproduced on a 9-scene storyboard project where every scene is a sub-composition. Before: a scene video and title carrying data-hidden both announced "Hide track N", and clicking left the file byte-identical. After: both announce "Show track N", and hide/show round-trips the attribute. A top-level clip with the same attribute always announced "Show", which is what made the gap specific to expanded child rows. The existing regression test passed throughout because its fixture hands the child a flat twin with hidden: true and gives the host no compositionSrc, so the child key falls back to the index.html scope and a twin can exist. The added test models a real sub-composition instead. |

feat(studio): let an agent edit text and styles, guarded (#3518)
* feat(studio): let an agent drive Studio's selection and playhead Adds `studio_select` and `studio_seek`, so an agent and the human are looking at the same element and the same instant. Selecting reveals the inspector, exactly as a click does, which is what makes the agent's move visible. Selection is shared state, not a per-call argument, and that is forced rather than chosen. Most of Studio's edit handlers read the ambient React selection, and `applyDomSelection` only schedules a state update, so selecting and committing inside ONE call would write to whatever was selected before. Two tool calls are separated by a render, so the contract is select first, then act. That is also how a human works: click, then type. `studio_seek` uses `requestSeek`, not `setCurrentTime`. The latter only moves the timeline's displayed number and leaves the composition where it was. Two things the tools refuse to fake: Seek does not clamp. `seek()` already clamps against the adapter's duration, which can differ from the store's, and clamping again would give that invariant two owners that can disagree. The tool reports where the playhead actually landed instead, read back afterwards. `requestSeek` is fire-and-forget, so it cannot report that no adapter was mounted to receive it. The tool compares the playhead before and after and fails rather than claiming a seek that never happened. Select separates three failures that a single message would have merged: the preview is not mounted yet (wait), no element matches the handle (re-read), and the element cannot be selected (try a neighbour). The agent's next move differs for each, so collapsing them would cost it a round trip or a retry loop. * feat(studio): give an agent eyes with studio_frame Renders the composition to a PNG at a given time and returns the URL. This is what turns the tool set from a remote control into a loop: author a change, capture the instant it affects, look, adjust.

Selecting reveals the inspector, exactly as a click does, which is what makes the agent's move visible. Selection is shared state, not a per-call argument, and that is forced rather than chosen. Most of Studio's edit handlers read the ambient React selection, and `applyDomSelection` only schedules a state update, so selecting and committing inside ONE call would write to whatever was selected before. Two tool calls are separated by a render, so the contract is select first, then act. That is also how a human works: click, then type. `studio_seek` uses `requestSeek`, not `setCurrentTime`. The latter only moves the timeline's displayed number and leaves the composition where it was. Two things the tools refuse to fake: Seek does not clamp. `seek()` already clamps against the adapter's duration, which can differ from the store's, and clamping again would give that invariant two owners that can disagree. The tool reports where the playhead actually landed instead, read back afterwards. `requestSeek` is fire-and-forget, so it cannot report that no adapter was mounted to receive it. The tool compares the playhead before and after and fails rather than claiming a seek that never happened. Select separates three failures that a single message would have merged: the preview is not mounted yet (wait), no element matches the handle (re-read), and the element cannot be selected (try a neighbour). The agent's next move differs for each, so collapsing them would cost it a round trip or a retry loop. * feat(studio): give an agent eyes with studio_frame Renders the composition to a PNG at a given time and returns the URL. This is what turns the tool set from a remote control into a loop: author a change, capture the instant it affects, look, adjust. No agent can judge motion from source, because "what does this look like at 2.4 seconds" is not a question a file answers. Reuses Studio's existing capture endpoint via `buildFrameCaptureUrl` rather than inventing a second one. Two things this does not fake: It reports the time the playhead LANDED on, not the time requested. The player clamps, so those differ at the ends, and attaching the wrong time to a frame is how an agent draws a confident wrong conclusion about motion. It waits before capturing, by default 150ms. The frame is rendered from the file on disk, and the render cache is cleared by a file watcher with a 40ms write-stability threshold, so a capture that beats the watcher renders the PRE-edit composition. That exact staleness was a real bug here once. An agent reading a stale frame as "my edit failed" would thrash, so the wait is on by default, `settleMs` makes it tunable, and the tool description names the failure rather than leaving it to be rediscovered. It probes with HEAD before returning, so a URL that 404s comes back as a failure with a hint instead of as a link the agent cannot render. * feat(studio): add studio_inspect, so an agent reads before it writes (#3517) Everything about one element in one call: resolved styles, text fields, box, data attributes, GSAP animations, and what the element will and will not accept. The point is to prevent a failed write rather than to satisfy curiosity. `can.reasonIfDisabled` is passed through verbatim from Studio's own capabilities, so an agent that reads first should never attempt an edit the element would refuse. Three things it refuses to get wrong: Animations are reported ONLY for the current selection, because that is the only element Studio parses them for. Attributing them to any other element would be reporting the wrong element's motion, which is worse than reporting none. When a handle names something else the field is empty and `animationEditingBlocked` says why. `animationEditingBlocked` also carries the two states where animation editing is off entirely, multiple timelines and an unsupported timeline pattern. Both live on the selection context. Learning them from a read costs one call; learning them from a failed write costs a retry loop. Inspecting a handle does NOT change what is selected. It is a read, and stealing the human's selection would be a side effect they did not ask for. There is a test asserting `applySelection` is never called. Nothing selected and no handle given is a failure, not an empty result. An empty result would assert "this element has nothing", which is a different and false claim. --------- Co-authored-by: miga-heygen <miguel.sierra_miga@heygen.com> Co-authored-by: Claude Opus 4.6 (1M context) <noreply@anthropic.com> |

fix(studio): export the composition the user has selected (#3550)
The header's Export button started renders with no options at all, so the request carried no `composition` and the server fell back to index.html. Selecting a sub-composition in the Comps panel showed its canvas and timeline but exported the root file instead. Studio starts renders from three controls, and the render target was owned by each of them separately: the Renders panel resolved it, the header omitted it, the sidebar's per-composition button named one explicitly. Give it one owner in `startRender`, which all three route through, defaulting to the active composition and leaving an explicit argument to win. Fixes #3549 |

fix(studio): activate a composition at any path, not just compositions/
The Comps panel sets activeCompositionPath to the selected file, but useCompositionStack's effect only pushed a stack level when that path started with compositions/. A project laying its comps out anywhere else, for example a generated multi-part build with parts/part-1.html next to the root index.html, matched no branch at all: the row highlighted and the URL hash updated while the stack silently kept the master mounted, so the canvas and timeline stayed on index.html and any edit landed in the root file instead of the part. Replaced the prefix test with a plain truthiness check, so the root stays on the master level and every other path pushes its own level. Label derivation is unchanged, matching CompositionsTab's own convention. |

fix(studio): update WebMCP test for polyfill fallback (#3532)
## Summary - The `useStudioAgentTools` test "registers nothing when the browser has no WebMCP" asserted `document.modelContext` was absent after mount - Since #3514 added the `@mcp-b/global` polyfill, the hook installs `document.modelContext` even without native browser support — that's the polyfill's purpose - Updated the test to verify that mounting doesn't throw (the real contract), without asserting polyfill absence This fixes the `CI / Test` failure on `main`. ## Other main CI failures (not ours) - **Docs / Validate docs** — `npm error notarget No matching version found for mint@4.2.837` (docs tool dependency) - **Windows / Tests on windows-latest** — `ECONNREFUSED ::1:3000` (Windows network test infra) - **regression** — cancelled, not failing ## Test plan - [x] All 9 `useStudioAgentTools` tests pass with `NODE_ENV=development` - [x] Pre-commit hooks: lint, format, fallow, typecheck all green — Miga 🤖 Generated with [Claude Code](https://claude.com/claude-code) |

fix(studio): update WebMCP test for polyfill fallback
The "registers nothing when the browser has no WebMCP" test asserted that document.modelContext was absent after mount. Since #3514 added the @mcp-b/global polyfill fallback, the hook now installs document.modelContext even when the browser has no native support — that is the polyfill's job. The real assertion is that mounting does not throw, which still holds. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> |

fix(producer): enforce video extraction failures by default (#3372) (#3526)
The extraction failure policy defaulted to "off", silently swallowing per-source errors. The plumbing to surface them (typed error, retryable classification, caller throw) was fully built but gated behind an env-var opt-in. Flip the default to "enforce" so extraction failures fail the render instead of producing misleading coverage aborts. Set HF_VIDEO_EXTRACTION_FAILURE_MODE=off to restore the old behavior.
