Compositions are now self-contained: the compiler captures font files
and embeds them as woff2 data URIs, eliminating silent render-time
fallback when the render environment lacks the author's fonts.
Resolution order (each tier falls through to the next):
1. Existing @font-face → use as-is
2. Bundled alias (38 cross-platform mappings) → embed data URI
3. Google Fonts → fetch, cache, embed
4. Local system font → locate on OS, compress to woff2, embed
5. Local @font-face paths → read file, compress, inline as data URI
6. External CDN stylesheets → fetch CSS, extract @font-face, inline
7. Alias map fallback → closest bundled equivalent
8. Actionable error with guidance
Key changes:
- System font locator (macOS/Windows/Linux) with path-bounding and
symlink defense (realpathSync + O_NOFOLLOW)
- woff2 compression via wawoff2 (WASM, cross-platform)
- Multi-weight/style variant capture with length-sorted token matching
- External stylesheet inlining with SSRF defense (assertPublicHttpsUrl,
HTTPS-only, private-host blocking, 2MB cap, 4-concurrent limit)
- Studio auto-import via GET /fonts/file API + renderAliasFor() derived
from shared FONT_ALIAS_MAP (no more hand-curated drift)
- failClosedFontFetch throws on unresolved fonts in distributed renders
- Single source of truth: @hyperframes/core/fonts/aliases
- system_font_will_alias lint rule (escalates to warning for distributed)
- Default to Inter + JetBrains Mono in templates and CSS reset
* feat(gcp-cloud-run): add Google Cloud Run + Workflows distributed render adapter
Adds @hyperframes/gcp-cloud-run, the GCP counterpart to @hyperframes/aws-lambda
(issue #932). The OSS distributed primitives (plan, renderChunk x N, assemble)
are unchanged; this package is the storage/compute/orchestration glue.
Package: Cloud Run handler (one image, three actions), runs under bun; GCS
transport; in-image chrome-headless-shell resolver; client SDK
(renderToCloudRun, getRenderProgress, deploySite, computeRenderCost); Dockerfile;
Cloud Workflows definition; Terraform module; CLI cloudrun
deploy|sites|render|render-batch|progress|destroy with --output-resolution and
--strict-variables; 62 unit tests + docs + live smoke script.
Shared extraction (removes ~640 lines of adapter duplication): move the
cloud-agnostic config validator + content-hash into producer/distributed; both
adapters import them. Validated end-to-end on GCP at 37.4 dB PSNR vs baseline.

* fix(cli): resolve @hyperframes/gcp-cloud-run in the CLI build + root build
The CLI bundle (esbuild) couldn't resolve `@hyperframes/gcp-cloud-run/sdk`,
failing Build/Typecheck/CLI-smoke (and the perf/windows/regression jobs that
build first). Mirror the aws-lambda handling: mark the gcp adapter + its /sdk
subpath external in tsup.config.ts with a source alias, and add gcp-cloud-run
to the root `build` filter so its dist exists for publish + runtime.

* fix(ci): copy gcp-cloud-run manifest in Dockerfile.test for frozen install
The regression test image runs `bun install --frozen-lockfile` after copying
each workspace package.json individually. The CLI now depends on
@hyperframes/gcp-cloud-run (workspace:*), so the frozen install fails to
resolve it unless its manifest is present. Add the COPY line.

* feat(cli): add machine-sizing flags to `cloudrun deploy`
Closes the parity gap with `lambda deploy` (which exposes --memory etc.).
`cloudrun deploy` now threads --cpu, --memory, --max-instances, and --timeout
into the Terraform apply; omitted flags keep the module defaults
(4 vCPU / 16Gi / 100 instances / 3600s). For finer control, apply the module
directly.

* fix(gcp-cloud-run): address PR review (security, waste, limits, alerts)
- server.ts: bucket-allowlist guard no longer fails open silently. Unset env
logs a one-time WARNING; "*" is an explicit opt-out; otherwise it enforces.
- server.ts: stop double-shipping audio.aac. It already rides in the plan
tarball every consumer downloads, so drop the redundant standalone upload
(plan) + re-download/overwrite (assemble); assemble reads it from the untar,
falling back to a supplied AudioGcsUri for compat.
- server.ts: chunk extension via path.extname() instead of slice(lastIndexOf).
- workflow.yaml: clamp parallel concurrency_limit to math.min(chunkCount, 20)
— Cloud Workflows hard-caps concurrent iterations at 20.
- Dockerfile: pin bun (bun-v1.3.9) so an interop change can't silently break
the image rebuild.
- terraform: add min_instances var (default 0); add a workflow-failure alert
(finished_execution_count status=FAILED) alongside the request-count one.
- costAccounting: document that displayCost excludes GCS storage/egress.
Verified against the actual APIs: @google-cloud/workflows@4.4.0
ICreateExecutionRequest has no executionId (so the idempotency-token suggestion
isn't available in this client); Workflows concurrency cap is 20; failure
metric is workflows.googleapis.com/finished_execution_count (status label).
174 adapter tests pass, fallow/oxlint/oxfmt/terraform clean.

* fix(gcp-cloud-run): address round-2 review — error code + CFR forwarding
- workflow.yaml: rename the zero-chunk failure code PLAN_TOO_LARGE →
PLAN_PRODUCED_ZERO_CHUNKS. The old code implied a size-ceiling breach (the
opposite cause), misleading anyone triaging the alert.
- workflow.yaml: forward Config.cfr to the assemble step
(`Cfr: ${("cfr" in config) and config.cfr}`). It was read by the handler
but never sent, so exact-CFR was silently off for every Cloud Run render.
Uses the same `in`-operator guard already proven in the retryable predicate.

* fix(release): include gcp-cloud-run in set-version PACKAGES list
set-version.ts (driven by release:prepare) bumps an explicit package list to
the shared version on each release. gcp-cloud-run was wired into the build +
publish.yml but missing here, so a release would leave it at a stale version
and publish.yml would push the wrong version. Add it so the new package
version-bumps + publishes in lockstep with the others.

* feat(gsap): add innerText support to GSAP inspector for counter animations (#1244)
Adds 'innerText' as a supported GSAP property so number roll-up animations
(count-up from 0 to some value) are visible and editable in the GSAP inspector
panel.
- Add 'innerText' to SUPPORTED_PROPS in gsapConstants.ts
- Add label 'Counter Value', tooltip, and step constraint (1) in
gsapAnimationConstants.ts
The snap modifier that controls integer rounding is already preserved
verbatim via the EXTRAS_KEYS round-trip, so rounding behavior survives
edits without any additional UI changes.
Closes#1179
* feat(registry): add text-effects catalog section and morph-text component
Introduces a new "Text Effects" catalog section (below Effects) for text-focused visual components.
- Add `text-effects` BlockCategory to core registry types with violet color
- Add `text-effect` tag resolver in resolveBlockCategory (checked before generic `effect` tag)
- Tag caption-blend-difference, texture-mask-text, and morph-text with `text-effect`
- Update studio catalog order and color map to include text-effects
- Add morph-text component: gooey SVG threshold morph cycling through editable statements
using GSAP seekable proxy pattern for deterministic/seekable rendering

* fix(registry): address PR review feedback on morph-text and text-effects
- Restore `effect` tag on caption-blend-difference and texture-mask-text
alongside `text-effect` so existing tag-equality searches/analytics still match
- Fix morphPause script fallback from "0.25" to "1.5" to match data attribute default
- Add Math.max(0, ...) guard to blur values (intent clarity)
- Add prefers-reduced-motion: skip morph and show first word statically
- Remove CATEGORY_ORDER record from useBlockCatalog; derive order from
BLOCK_CATEGORIES array (single source of truth, no drift)

* fix: batch GSAP timeline construction to prevent main-thread hang (#1231)
Compositions with thousands of tl.to() calls (e.g. 8,562 in the
reported case) block Chrome's main thread synchronously during HTML
parsing, preventing DOMContentLoaded from firing before Puppeteer's
navigation timeout. This caused render jobs to hang indefinitely at
'Initializing calibration session...' with no error message.
Root cause: GSAP's timeline API is synchronous — each tl.to() call
registers a tween immediately on the main thread. A script with 8k+
calls holds the thread for seconds, starving the browser event loop and
delaying DCL past the navigation timeout window.
Fix: install a property trap on window.gsap in HF_EARLY_STUB (injected
at the top of <head>, before GSAP or user scripts load). When GSAP
assigns itself to window.gsap, the setter intercepts the real gsap
object and wraps gsap.timeline() to return a proxy that queues tween
descriptors (to/from/fromTo/set) instead of calling them synchronously.
A requestAnimationFrame-based flush loop drains 100 tweens per frame,
yielding the main thread between batches so DCL can fire.
When the queue is drained, the stub sets window.__hfTimelinesBuilding =
false and dispatches a 'hf-timelines-built' CustomEvent. init.ts checks
this flag at DOMContentLoaded time; if building is still in progress it
defers bindRootTimelineIfAvailable() until the event fires, then sets
window.__renderReady = true as normal. pollHfReady continues to gate
on both __renderReady and window.__hf.duration > 0, so the render
pipeline does not start until the full timeline is bound.
- Batch size: 100 tweens/rAF tick (empirical; ~4ms/batch at 8k scale)
- Yield mechanism: requestAnimationFrame (cooperative, no setTimeout(0))
- Determinism: 'hf-timelines-built' event guarantees sequencing
- Proxy forwards: pause/seek/totalTime/time/duration/add/paused/
timeScale/play delegate to the real timeline immediately
- No GSAP package changes; no navigation timeout increase
Fixes#1231
* style: apply oxfmt formatting to producer stub files
* fix(producer): unwrap proxy children in add(), gate setter return on args.length
Addresses two latent correctness concerns from code review:
1. proxy.add() now unwraps __hfReal from any proxy child before passing it
to the real timeline. GSAP's internal tween graph (_first/_next/_prev
linkage) requires real timeline instances — proxy objects lack internal
fields like _dp that GSAP's iteration paths expect.
2. totalTime/time/paused/timeScale now return proxy when called in setter form
(args.length > 0). Previously these returned the real timeline, causing
callers who chain .to(...) after a setter call to bypass batching.
Also: build-hf-early-stub.ts now runs oxfmt on the generated output file
so the format check passes in CI on every build.
* fix(producer): gate __hf.duration=0 while GSAP timelines are batching
The HF_BRIDGE_SCRIPT duration getter now returns 0 whenever
window.__hfTimelinesBuilding is true (set by HF_EARLY_STUB while the rAF
batch loop is draining queued tl.to() calls).
pollHfReady in the engine polls until window.__hf.duration > 0, so
returning 0 keeps the engine waiting until the hf-timelines-built event
fires and all tweens are committed to the real GSAP timelines.
Without this gate, normal compositions (style-6, style-13, vignelli)
were being captured mid-batch — the real timelines were empty so GSAP
could not seek them, producing frozen/blank frames in the output video.
* fix(producer): flush GSAP batching under virtual time
* fix(producer): gate render bridge on runtime readiness
* fix(producer): preserve timeline child binding under batching
## What
Extends `editHistory.test.ts` with T11 from the SDK migration test plan: history coalescing gaps and origin guard stubs.
## Tests
**New passing test (1):**
- **cross-prop coalescing separation** — two edits within the coalesce window but with *different* `coalesceKey` values produce two separate undo entries, not one coalesced entry. Fills the gap left by the existing same-file coalescing tests (lines 176–243).
**`.todo` stubs (2):**
- `gesture-start/commit collapses intermediate drag steps into one undo entry` — requires gesture lifecycle API not yet built
- `origin:applyPatches edits excluded from undo stack` — requires SDK session object (`session.on("patch", ...)`, `session.dispatch(...)`) which doesn't exist yet; needed to prevent undo loops when SDK patches are applied
## Stack
Stacked on T8 (#1241). Prerequisite for T4 (#1243).
## What
Extends `getVariables.test.ts` with T8 from the SDK migration test plan: override-set merge semantics.
## Tests (4 new)
- **last-write-wins** — calling `setOverrides` twice; second value wins
- **sparse override** — override one key, unmentioned declared defaults survive intact
- **batch override (brand kit)** — setting all keys at once via a single override object
- **manual override after batch** — replacing one key from a kit batch; others untouched
## Scope note
Tests are labeled **"flat-merge, current behaviour"** — `getVariables` does `{...defaults, ...overrides}`. Dotted-key path resolution (`"headline.color"` as `id.prop`) is a future SDK concern; these tests validate the flat-merge contract that exists today, not the future path-resolution semantics.
## Stack
Stacked on T1 (#1240). Prerequisite for T11 (#1242), T4 (#1243).
## What
Adds `htmlParser.roundtrip.test.ts` — T1 from the SDK migration test plan.
Tests that `parseHtml → generateHyperframesHtml → parseHtml` is lossless for element structure and timing. Scope is DOM/timing only; GSAP script round-trip is T6 territory.
## Tests
**Inline fixtures (5):**
- element count + ids preserved
- `startTime` / `duration` preserved
- element types preserved (`text`, `video`, `img`, `audio`)
- double-serialize stability (`serialize(parse(serialize(parse(html)))) === serialize(parse(html))`)
- empty stage doesn't throw
**Registry block sampling (10):** first 10 blocks in `registry/blocks/` — each asserts element count survives a round-trip.
## Finding
Stability test surfaced a real bug: `generateHyperframesHtml` defaults `compositionId` to `` `comp-${Date.now()}` ``. Since `ParsedHtml` doesn't capture this, every re-serialize emits a different id. The test works around it by passing a fixed `compositionId: "test-comp"` so structural instability is still detectable. The root cause is tracked as **R1 (stable hf- ids)**.
## Stack
Prerequisite for: T8 (#1241), T11 (#1242), T4 (#1243)
Adds 'innerText' as a supported GSAP property so number roll-up animations
(count-up from 0 to some value) are visible and editable in the GSAP inspector

Closes#1179
Page.goto with waitUntil:'load' blocks until all video sources finish
preloading metadata. With 6+ video sources (8–21s each), this reliably
exceeds the 60s navigation timeout, causing renders to hang at
'Initializing calibration session...' on M4 and other Apple Silicon macs.
Switch to waitUntil:'domcontentloaded' so navigation resolves as soon as
the DOM is ready, without gating on video media loading.
Fixes#1231
* fix(producer): thread forceScreenshot to probe stage for low-memory mode
The render orchestrator sets captureForceScreenshot=true when low-memory
mode is active and passes it to all three capture stages, but never
passed it to the probe stage. The probe stage received the original cfg
with forceScreenshot=false, so on Linux it launched the browser in
beginframe mode — which hangs on memory-constrained hardware.
Add a forceScreenshot parameter to ProbeStageInput (matching the pattern
used by captureStage, captureStreamingStage, and captureHdrStage) and
wire it through from both the render orchestrator and the distributed
planner.
Fixes heygen-com/hyperframes#1236
* fix(producer): add lowMemoryMode→forceScreenshot bump in distributed plan + regression test
- plan.ts: mirror the renderOrchestrator's lowMemoryMode bump so that
distributed runs on low-RAM hosts also force screenshot capture mode.
Previously the bump was only applied in the in-process path (renderOrchestrator.ts:1598);
plan.ts derived forceScreenshot from compileResult without the bump, leaving the
distributed probe stage in beginframe mode on low-memory hosts (same shape of bug as #1236).
Added TODO to unify the bump into compileStage so all paths share one source of truth.
- probeStage.test.ts: add regression test pinning that createCaptureSession
receives forceScreenshot:true when the stage input carries it but cfg.forceScreenshot
is false (low-memory mode override). Mirrors worker-count test shape from
captureStreamingStage.test.ts. Two cases: override active, override inactive.
Addresses review feedback from #1237.
* fix(producer): restore 30s calibration timeout ceiling to prevent render hang
The v0.6.74 change (Math.min → Math.max in createCaptureCalibrationConfig)
raised the calibration protocol timeout from 30s to the default 300s. When
a CDP call stalls during session init — page.goto, pollHfReady, or any
page.evaluate — the 300s timeout makes the render appear to hang
indefinitely at "Initializing calibration session...".
Restore Math.min so calibration stays capped at 30s: if Chrome is stuck,
fail fast and let the fallback path recover. Also add phase-level timing
logs to initializeSession so the next report pinpoints which step stalls.
Closes#1231
* fix(producer): add render pipeline observability for faster triage
Log the resolved environment at pipeline start (platform, arch, node
version, all timeout values, GPU mode), the calibration config showing
the actual timeout being used vs the parent, Chrome version and capture
mode at browser launch, and a structured failure summary on error with
stage timings and console errors. These four log categories give agents
and users enough context to file actionable issues without needing to
reproduce the problem.
* fix(engine): add missing pollVideosReady phase log in screenshot path
The BeginFrame path logged this phase but the screenshot path didn't,
creating an instrumentation gap when diagnosing hangs on macOS where
screenshot mode is always used.
## Summary
- Adds `validateEventS3Uris()`, called immediately after `unwrapEvent()` in the Lambda handler before any S3 I/O.
- If `HYPERFRAMES_RENDER_BUCKET` env var is set, every S3 URI in the event (`ProjectS3Uri`, `PlanOutputS3Prefix`, `PlanS3Uri`, `ChunkOutputS3Prefix`, `ChunkS3Uris`, `AudioS3Uri`, `OutputS3Uri`) must resolve to that bucket. Mismatches throw `S3_URI_NOT_ALLOWED`.
- Env var unset → validation skips (backwards-compatible; existing deployments without the var continue to work).
- CDK stack (`HyperframesRenderStack`) auto-wires `HYPERFRAMES_RENDER_BUCKET: this.bucket.bucketName` so new deployments are protected without manual config.
- `S3_URI_NOT_ALLOWED` added to all three `NON_RETRYABLE_*` lists in the Step Functions state machine so the state machine does not retry on this error.
## Security
**F-004 MED** — The Lambda handler accepted S3 URIs from the event payload without verifying they targeted the function's own render bucket. An attacker who could inject a crafted Step Functions execution input could route `GetObject` / `PutObject` calls to arbitrary buckets in the same AWS account, potentially exfiltrating plan data or overwriting objects in unrelated buckets.
## Test plan
- [x] `handler` rejects a `plan` event whose `ProjectS3Uri` targets a different bucket — `S3_URI_NOT_ALLOWED` thrown, zero S3 ops recorded
- [x] `handler` rejects an `assemble` event with one cross-bucket chunk URI
- [x] Validation is skipped when `HYPERFRAMES_RENDER_BUCKET` is unset (no regression for existing callers)
- [x] All 12 handler unit tests pass
* feat(studio): add drag-to-reorder in layers panel with z-index persistence
Layers panel now sorts siblings by computed z-index (descending) to
reflect visual stacking order. Users can drag layer rows to reorder
them within a sibling group — on drop, sequential z-index values are
assigned and persisted via the existing inline-style patch pipeline
with a single preview reload.
- sortLayersByZIndex: recursive sibling-group sort by computed z-index
- useLayerDrag: pointer-capture drag gesture with 4px threshold,
insertion indicator line, and depth-constrained sibling reorder
- handleDomZIndexReorderCommit: batch z-index commit with coalesced
undo entry and single skipRefresh=false on the final patch
* fix(studio): harden layer drag-to-reorder edge cases
- Guard drag initiation against locked compositions by checking
data-timeline-locked ancestors in isLayerDraggable
- Show not-allowed cursor and reduced opacity on non-draggable layer rows
- Fire toast when attempting to drag a layer with no same-depth siblings
- Preserve z-index spacing on reorder by redistributing existing values
instead of flattening to sequential integers
- Auto-set position:relative on unpositioned elements when z-index is
applied so the stacking order actually takes visual effect
- Add tests for isLayerDraggable (anonymous, id, selector, locked, free)
* fix(studio): handle z-index ties in layer reorder + trim file sizes
- Fall back to sequential z-index when any duplicates exist in the
sibling set, not just when all values are identical — fixes silent
no-op reorder when tied values preserve DOM-order stacking
- Trim useDomEditSession.ts from 602 to 600 lines (CI file-size gate)
* test(studio): add duplicate z-index tiebreak test for layer sorting
Cover the [2, 1, 2] case where tied z-index values fall back to
reverse DOM order — locks the hasDupes fix against regressions.
* style(studio): fix oxfmt formatting in LayersPanel
## Summary
- Adds `safeFetch`, a redirect-aware wrapper around `fetch` that re-runs the SSRF denylist on every hop before following a redirect.
- Routes `fetchBuffer` and the Lottie media fetch through `safeFetch` so redirect chains can't bounce through a public URL to reach an internal or cloud-metadata host.
- Hardens `isPrivateUrl` to also block `0.0.0.0` / `0.0.0.0/8`, IPv6 loopback (`::1`), IPv4-mapped (`::ffff:…`), unique-local (`fc00::/7`), and link-local (`fe80::/10`) ranges.
## Security
**F-002 MED** — `fetchBuffer` followed redirects without re-checking the denylist on the destination. A `30x` redirect from an allowlisted public URL to `169.254.169.254` or an internal host would succeed, leaking the response to the caller (e.g. captured page assets written to local disk).
**F-003 MED** — `isPrivateUrl` did not cover `0.0.0.0` (maps to localhost on most OSes), IPv6 loopback, or IPv6 private ranges. An asset URL using those addresses would bypass the denylist. Alternate IPv4 encodings (decimal/octal/hex) are already normalized to dotted-quad by WHATWG URL parsing and remain blocked.
## Test plan
- [x] Unit tests cover redirect-chain blocking (redirect to metadata IP rejected)
- [x] Unit tests cover new `isPrivateUrl` address forms (`0.0.0.0`, `::1`, `fc00::1`, `fe80::1`, `::ffff:192.168.1.1`)
- [x] Existing fetch and asset-download tests pass
## What
Adds an auto-detected **low-memory safe render profile**. On hosts at or below 8 GB total RAM, the render pipeline collapses to its cheapest shape instead of running multiple concurrent Chrome instances.
When `lowMemoryMode` is active and the user hasn't passed `--workers`, the orchestrator:
- **skips auto-worker calibration** — no throwaway second Chrome just to time 5 frames;
- **pins to a single worker** — so the probe Chrome is reused for capture, never N concurrent;
- **prefers screenshot capture over BeginFrame** — avoids the BeginFrame protocol-timeout → relaunch churn on slow hardware;
- logs a one-line explanation of what it did and how to override.
Builds on #1221 (merged), which fixed the calibration timeout cap, the `<= 8192` boundary, and added the CLI timeout flags.
## Why
Reported in #1218 / #1219: renders on 8 GB laptops sit at low progress for minutes or stall. Root cause (per the triage thread) is architectural — the default pipeline launches up to 4 Chrome instances sequentially/overlapping (probe, calibration, capture, screenshot-fallback), each ~256 MB+, on machines with ~3 GB free. The concurrent browsers drive memory pressure that makes every CDP call slow and spikes V8 GC pauses.
#1221 made the timeouts and memory flags *apply correctly*; this PR removes the expensive shape entirely on the machines that can't afford it, rather than tuning it. "Smarter by default."
## How
- **`packages/engine/src/services/systemMemory.ts`** (new): one shared `isLowMemorySystem()` / `getSystemTotalMb()`, de-duplicating the `totalmem()` reads previously copied in `config.ts` and `browserManager.ts`. Threshold is inclusive (`<= 8192 MB`) — real "8 GB" hardware reports ~7600–8192 MB after firmware/iGPU reservations, so a strict `<` would skip the optimisation on the very hardware that needs it.
- **`config.ts`**: new `lowMemoryMode` field on `EngineConfig`, resolved tri-state — explicit override → `PRODUCER_LOW_MEMORY_MODE` (on/off) → auto-detect from total RAM.
- **`renderOrchestrator.ts`**: gate calibration off, pin workers to 1, force screenshot capture, and emit a safe-mode log line when `lowMemoryMode` is set and `--workers` is absent.
- **`render.ts`**: `--low-memory-mode` / `--no-low-memory-mode` override (sets the env var the producer's `resolveConfig` reads) + docs table entry.
Fully overridable: an explicit `--workers N` restores calibration-free parallelism; `--no-low-memory-mode` / `PRODUCER_LOW_MEMORY_MODE=false` restores the full default shape.
### Deliberately deferred (separate PRs)
- **Reuse the probe session for calibration**: only executes on the tier *above* 8 GB (safe-mode skips calibration on the target boxes). A correct BeginFrame-mode reuse would lose calibration's fast-fail-to-screenshot timeout — real risk on a path the reported scenario never hits. Better scoped on its own.
- **Retuning `calculateOptimalWorkers`'s `totalmem*0.5/256` memory model**: hot path for *all* renders incl. servers/Lambda, outside this PR's local-laptop scope.
## Test plan
- [x] Unit tests added/updated — `systemMemory.test.ts` (8192 boundary cases), `config.test.ts` (tri-state env resolution + explicit-override precedence). Engine suite passes (25 relevant tests).
- [x] `tsc` clean across engine/producer/cli; `oxlint` + `oxfmt` clean; removed an unused export so the `fallow --fail-on-issues` dead-code gate stays green.
- [x] Documentation updated — `docs/packages/cli.mdx` render-flags table.
- [ ] Manual testing on a real ≤ 8 GB host — not yet run; behaviour is unit-covered and the safe path (1 worker + screenshot) is already a supported render shape.
Note: one pre-existing producer test (`rejects a maliciously crafted key…`) fails identically on `main` — environment-specific path test, unrelated to this change.
The fit-to-children merge re-inlined TimingSection that was already
extracted to propertyPanelTimingSection.ts, pushing the file to 687

- Extracted computeFitToChildrenSize to propertyPanelHelpers
- Formatted PropertyPanel.tsx (608 lines, down from 687)
Adds an icon button next to W/H fields that computes the bounding

- resolveSnapAdjustment called per pointermove during drag
- resolveResizeSnapAdjustment for resize gestures
- lastSnappedDx/Dy stored on GestureState for consistent drop
- Alt/Option key temporarily disables snap
- SnapToolbar rendered in preview area with snap prefs state
React components and DOM utilities for the snap system:
- SnapGuideOverlay: pre-allocated div pool (6 guides + 4 spacing)
for ref-driven guide line rendering during drag
- SnapToolbar: magnet/grid toggle with S/G keyboard shortcuts,
right-click grid popover for spacing config
- GridOverlay: CSS repeating-linear-gradient grid, GPU composited
- snapTargetCollection: walks iframe DOM tree to collect visible
elements as snap targets, cross-iframe safe (nodeType check)
## Summary
- Binds the Studio preview server (`packages/cli`) to `127.0.0.1` instead of `0.0.0.0` so it is only reachable from localhost.
- Adds a `--host` flag for callers that genuinely need to expose the server on a wider interface (e.g. Docker, remote dev boxes).
## Security
**F-001 HIGH** — Studio preview server was binding on all interfaces, making it reachable from any network the developer's machine was on (including shared Wi-Fi, corp LAN). Because the server serves the project filesystem under no auth, any peer on the same network could read arbitrary project files. Restricting to loopback closes this exposure for the default case.
## Test plan
- [x] `hyperframes preview` starts — server reachable on `localhost:<port>`, not on LAN IP
- [x] `hyperframes preview --host 0.0.0.0` still binds on all interfaces for Docker / remote-dev use cases
- [x] Existing unit tests pass
`init.ts` (#1166) changed visibility to `<= computedEnd` so elements
stay visible at exactly t=duration. Audio clock (`init.ts:1908`) and
`syncRuntimeMedia` (`media.ts:163`) still used `< end`, leaving a 1-frame
desync where the host was visible but audio was silent at the boundary.
Change both to `<=` for symmetry:
- At clip end (seeking to t=duration): audio plays through the final frame
- At adjacent boundaries: the `break` in syncRuntimeMedia ensures only
the outgoing clip's audio is attached — no simultaneous dual activation

* fix: add progress logging during silent render pipeline stages
The render pipeline only updates progress at stage boundaries (5%, 10%,
25%), leaving multi-minute gaps with zero log output on low-memory
hardware. This adds log.info calls at key sub-steps within the three
silent stages:
- Probe stage (5%): browser launch, session initialization, duration
discovery, media asset discovery, audio volume automation, video
visibility window detection
- Video extraction (10%): per-video extraction progress
- Calibration (25%): browser launch, session initialization,
per-frame calibration progress, final cost estimate
Also adds 30-second heartbeat timers for the two initializeSession
calls (probe and calibration) that can individually take minutes on
constrained hardware.
Closes#1218
* fix: resolve CI failures in typecheck, runtime seek test, and timeline test
- Make handleGsapMaterializeKeyframes optional in DomEditSessionSlice
and use optional chaining at the call site (not yet wired)
- Update GSAP adapter seek test to expect nudge+seek pattern
(totalTime with suppressEvents:true followed by actual seek)
- Fix Timeline canvas height test to use TRACK_H constant (48)
instead of stale hardcoded value (72)
* refactor: extract helpers to meet 600-line file size limit
- App.tsx (603→594): extract StudioToast component
- useDomEditSession.ts (688→600): extract useGsapSelectionHandlers hook
- Timeline.tsx (614→557): extract useTimelineAssetDrop hook
- PropertyPanel.tsx (647→584): extract TimingSection to propertyPanelTimingSection
* style: fix formatting in TimelineToolbar
Closes#1219
## Problem
On 8GB RAM machines, renders time out at 5% with `Runtime.callFunctionOn timed out` during the duration probe. User-set timeout env vars (`PRODUCER_PUPPETEER_PROTOCOL_TIMEOUT_MS`) are silently ignored by the calibration path, and there are no CLI flags to control timeouts directly.
## Root causes
1. **Calibration timeout cap overrides user settings** — `createCaptureCalibrationConfig` used `Math.min(cfg.protocolTimeout, 30_000)`, meaning even if the user set 300s, calibration still capped at 30s. On slow hardware this causes unnecessary timeouts.
2. **8GB systems get no low-memory treatment** — `getLowMemoryFlags()`, `getGpuMemBudgetMb()`, `memoryAdaptiveCacheLimit()`, and `memoryAdaptiveCacheBytesMb()` all used `< 8192` as the threshold. Systems reporting exactly 8192 MB (common for 8GB machines) fell through to the "plenty of memory" path, getting no Chrome heap reduction or cache limits.
3. **No CLI flags for key timeouts** — Users had to discover the correct env var names (`PRODUCER_PUPPETEER_PROTOCOL_TIMEOUT_MS`, `PRODUCER_PLAYER_READY_TIMEOUT_MS`) by reading source. The non-existent `PUPPETEER_PROTOCOL_TIMEOUT` and `--browser-timeout` were common guesses that did nothing.
## Changes
- `captureCost.ts`: `Math.min` → `Math.max` so the 30s calibration default is a floor, not a ceiling. User-set higher timeouts are now respected.
- `browserManager.ts`: `>= 8192` → `> 8192` in `getLowMemoryFlags()` and `<= 8192` in `getGpuMemBudgetMb()` so 8GB systems get reduced Chrome heap and GPU memory budget.
- `config.ts`: `< 8192` → `<= 8192` in `memoryAdaptiveCacheLimit()` and `memoryAdaptiveCacheBytesMb()` so 8GB systems get reduced frame cache limits.
- `render.ts`: Added `--protocol-timeout <ms>` and `--player-ready-timeout <ms>` CLI flags, wired through `resolveConfig` overrides.
- Updated calibration tests to match the new floor-not-ceiling behavior.
- Added fallow suppressions for pre-existing unused exports in `captureCost.ts`.
## Test plan
- [x] Engine config tests pass (`vitest run src/config.test.ts`)
- [x] Browser manager tests pass (`vitest run src/services/browserManager.test.ts`)
- [x] Calibration safeguard tests pass (4/4 in `renderOrchestrator.test.ts`)
- [x] TypeScript compiles cleanly for engine and cli packages

by the element's CSS --hf-studio-rotation angle before adding.

Position, resize, and rotation intercepts now read ALL animated

* fix(studio): overlay jump, delete-all-keyframes, split wiring, reapplyBoxSizes guard
- Fix overlay bounding box jump: reapplyBoxSizes now skips elements whose
width/height are animated by GSAP (gsapAnimatesProperty check prevents
studio CSS from overwriting GSAP interpolated values)
- Delete All Keyframes removes entire animation (handleGsapDeleteAnimation)
with fallback to first animation when no keyframed anim exists
- Wire split clip through App → StudioPreviewArea → NLELayout → Timeline
(onSplitElement prop, toolbar button, S hotkey, clip context menu)
- Add onContextMenu to TimelineClip for right-click clip context menu
* fix(studio): block split on sub-compositions
Sub-compositions (data-composition-src) cannot be meaningfully split —
the clone would load the same source and fight for the same timeline.
Block with a specific toast message and disable in the context menu.
* fix(studio): no toast when split is unavailable for compositions

* feat(studio): runtime-synced design panel values + 3D transform properties
The Layout section (X, Y, W, H, R) now reads GSAP-interpolated values
from the runtime via gsap.getProperty() at the current seek time. When
an element has GSAP animations, the fields reflect the actual interpolated
position/size/rotation instead of the CSS defaults.
Also adds 3D transform properties to SUPPORTED_PROPS: z, rotationX,
rotationY, rotationZ, perspective, transformOrigin.
* fix(studio): read ALL animated properties from runtime, not just hardcoded 7
* fix(studio): stronger clip selection border + wider keyframe playhead tolerance
- Selected clip: full accent border (was 38% opacity), subtle glow shadow
- Keyframe diamond at playhead: tolerance 0.5% (was 0.05% — too tight at
high zoom levels, causing diamonds to never highlight)
* fix(studio): sync DOM selection to timeline selectedElementId on cold load
* fix(studio): use Phosphor Scissors icon for split button
* fix(studio): restrict split to media elements only (video, audio, img)
* feat(studio): unified commitAnimatedProperty for all GSAP property edits
Extract useAnimatedPropertyCommit hook that handles the three-case commit
logic: keyframed → add-keyframe, flat → convert + add, no animation →
create + convert + add. Wire Z, Scale, RotX, RotY design panel fields
and 2D Layout fields through this unified pipeline.
Export readAllAnimatedProperties and readGsapProperty from the runtime
bridge so the commit helper can read all animated props for backfill.

These design plans were accidentally committed and should not be in
the PR.

Read GSAP keyframe data from the live runtime instead of only the AST parser.
Dynamic keyframes (loops, variables, computed selectors) now show diamonds

On first edit, dynamic code is automatically materialized:
- Unresolved keyframes (keyframes: kf) replaced with static object
- Unresolved selectors (tl.to(sel, ...)) entire loop unrolled into
individual static tl.to() calls per element
Key changes:
- Parser: hasUnresolvedKeyframes/hasUnresolvedSelector flags
- Runtime bridge: scanAllRuntimeKeyframes reads tween.vars from iframe
- Tween cache: interval-based runtime scan for dynamic animations
- materializeKeyframesInScript + unrollDynamicAnimations parser functions
- Keyframe cache dual-writes both sourceFile#id and index.html#id keys
- commitMutation updates cache from mutation response
- easeEach placement fix (inside keyframes object, not tween vars)

* fix(runtime): don't restart non-loop media that has naturally ended
When a media element's authored data-duration exceeds the actual file
length, el.ended becomes true at the file's natural end while the clip
is still considered 'active' (timeSeconds < clip.end). The runtime was
calling el.play() on the ended element every rAF tick, resetting
currentTime to 0 and causing audible stutter for the overshoot duration.
Fix: treat el.ended as inactive for non-loop clips. The element sits
silently until the composition ends. el.ended resets to false on any
seek, so scrubbing backward correctly resumes playback.
Reproducer: bg-music WAV is 60s but data-duration='68.6' (composition
duration). Last 8.6s: rapid play->clamp->end->play cycle at 60fps.
* test(runtime): add seek-recovery contract test for el.ended guard
Adds a third test case pinning the seek-recovery property called out in
the PR body: a clip that went silent at t=62 (el.ended=true) should
resume playing after a backward seek resets el.ended to false.
