fix(cli): contrast gate judges only readable content; examples pass check
Three filters keep the escalated contrast gate honest, each surfaced by running check across the registry examples: - data-layout-ignore (the layout audit's existing decorative opt-out) now also excludes set-dressing text from the contrast audit — one vocabulary for 'not copy a viewer must read'. - Text that has (nearly) left the canvas is skipped: sampling a clamped off-canvas box reads border pixels and produced the classic false white-on-white (a cursor exiting the frame). - Contrast failures follow the same persistence rule as layout findings: observed at a single sample of a multi-sample sweep demotes to warning; held failures gate. Example fixes the sweep exposed: motion-blur's 21 deliberately-dim rail labels are marked decorative (its vivid labels pass on their own); nyt-graph's subtitle and source-note adopt the gate's suggested compliant gray; decision-tree's declared duration drops 15s to 10s — its content ends at ~9.5s and every render shipped a blank white tail. |

fix(cli): sample real pixels behind hidden text for contrast-audit
## What Fixes five reported false-positive/false-negative patterns in the WCAG contrast audit (`hyperframes validate --contrast`): 1. **SVG fill vs. text color** — foreground read from CSS `color` instead of SVG `fill`. 2. **Cross-component color bleed** — background estimate bleeds into a neighboring panel/layer. 3. **Backdrop-filter glass text** — background estimate misses the blur/tint and reads the raw backdrop. 4. **Partially-overlapping translucent decoration** — a decorative shape inside or partly touching the text's bbox goes undetected. 5. **Solid-fill pill/button** — investigated, did **not** reproduce; already handled correctly by the existing own-background ancestor walk. Not touched. ## Why The audit estimated an element's background two ways: - foreground: always `getComputedStyle(el).color` — wrong for SVG `<text>`/`<tspan>`, which is painted via `fill`, an independent CSS property. - background: a 4px pixel ring sampled just **outside** the text's bounding box, with a fallback to an ancestor's opaque `background-color` for solid pills/buttons. The ring is a proximity heuristic. It's wrong whenever what's immediately outside the text differs from what's actually behind it: - text near the edge of its own panel, with a differently-colored sibling panel/layer just past the bbox — the ring samples the neighbor. - a `backdrop-filter: blur()` glass panel sized only a couple pixels larger than the text — the ring exits the panel into the raw, unblurred, untinted backdrop. - a translucent decoration that only partially overlaps the ring, or sits entirely **inside** the bbox — invisible to the ring regardless of size. ## How **SVG fill (#1):** elements inside an `<svg>` (`el.ownerSVGElement`) now prefer the computed `fill` when it resolves to a solid `rgb()`/`rgba()` color, falling back to `color` for paint values that aren't a plain color (`none`, `context-fill`, gradient/pattern refs). **Cross-comp bleed / glass blur / partial decoration (#2–#4):** replaced the ring-sampling + own-background-ancestor-walk heuristic with a two-phase capture: 1. `__contrastAuditPrepare()` walks the DOM, computes each candidate's foreground (unchanged logic from #1), and **hides that element's own text paint** (`color`/`fill` → `transparent`, layout-neutral — no reflow). 2. The caller takes **one** screenshot with the glyphs invisible (same number of screenshots as before — just moved after the hide instead of before it). 3. `__contrastAuditFinish(imgBase64, time, candidates)` restores the original paint immediately, then samples the **real composited pixels directly inside each element's own bbox** — no proximity heuristic needed, since these are the exact pixels that were behind the glyphs. This is a real architectural change to `contrast-audit.browser.js`'s calling contract (single `__contrastAudit` → `__contrastAuditPrepare`/`__contrastAuditFinish`), with `validate.ts`'s `runContrastAudit` updated to match, including a try/finally restore-safety-net so a mid-loop screenshot/decode failure can't leave a later sample auditing a page with stale hidden text. Mirrored the identical change in `skills/hyperframes-creative/scripts/contrast-report.mjs`, which duplicates the same DOM-walk/sampling logic (not just the WCAG math). There, the **visible** frame for the human-facing overlay image still comes from the producer's normal `captureFrameToBuffer` path (unchanged); only the **background-sampling** capture is a plain `session.page.screenshot()` taken after hiding text — deliberately bypassing `captureFrameToBuffer`, whose static-frame dedup cache knows nothing about the DOM mutation and would hand back a stale pre-mutation buffer. **Solid-fill pill (#5):** reproduced a rounded pill/button with a busy page background outside it. The existing own-background ancestor walk already resolves the pill's declared `background-color` correctly regardless of the rounded corners — confirmed via repro, both before and after this change report the identical (correct) result. No fix needed; left untouched, and this case is covered by the new architecture too (would give the same right answer even without the ancestor-walk fallback). Added `packages/cli/src/commands/contrast-sample.ts` (mirroring the existing `contrast-bg.ts`/`contrast-fg.ts` pattern) hosting the pure sample-rect/grid-point computation, unit tested — the browser-injected scripts can't import it directly, so it's kept in sync by hand, same convention as the rest of this file. ## Test plan - [x] Unit tests: `contrast-fg.test.ts` (SVG fill resolution), `contrast-sample.test.ts` (sample-rect clamping/degenerate cases), plus the full `packages/cli` suite (1424 tests) passes, including an updated `layout-audit.browser.test.ts` case that called the old single-function `__contrastAudit` API directly. - [x] Manual verification — standalone `puppeteer-core` harness against real `chrome-headless-shell`, one minimal HTML fixture per pattern, comparing the audit's reported ratio/verdict against a hand-constructed ground truth: - **SVG fill**: `fill:white` / no `color` on black bg → before: `fg=rgb(0,0,0)` ratio `1:1` (false FAIL); after: `fg=rgb(255,255,255)` ratio `21:1` (correct PASS). - **Cross-comp bleed**: text on a black sibling highlight box 2px larger than the text, white page bg outside it → before: `bg=rgb(255,255,255)` ratio `1.23:1` (false FAIL); after: `bg=rgb(0,0,0)` ratio `17.14:1` (correct PASS). - **Glass blur**: black text on an 18%-white-tinted `backdrop-filter: blur(14px)` panel over a yellow/blue gradient, panel only ~2px larger than the text → before: `bg=rgb(0,64,255)` (raw gradient color, blur/tint completely missed) ratio `3.18:1` (false FAIL); after: `bg=rgb(159,160,165)` (correct blurred/tinted blend) ratio `8.05:1` (correct PASS). - **Partial decoration**: text 92%-covered by a translucent white badge on a dark bg → before: `bg=rgb(16,16,16)` (ring never touches the badge, which sits entirely inside the bbox) ratio `17.45:1` (false PASS); after: `bg=rgb(171,171,171)` (correctly detects the badge) ratio `2.11:1` (correct FAIL). - **Solid pill sanity**: unaffected — `bg=rgb(10,10,10)` ratio `19.8:1` before and after. - [x] End-to-end: ran the actual `hyperframes validate --contrast` CLI command (via `tsx src/cli.ts`) against a real scaffolded project containing all 4 patterns simultaneously — only the genuinely-failing case (the 92%-covered decoration) is reported (`1.09:1`, need `3:1`); the cross-comp-bleed, glass-blur, and solid-pill cases are correctly silent. A second vanilla scaffold with plain white-on-dark text produces zero false positives. - [x] `oxlint`, `oxfmt --check`, and `tsc --noEmit` all pass on the changed files. |

fix(cli): contrast audit reads an element's own opaque background (#1975)
The WCAG contrast audit estimated each text element's background by sampling a 4px pixel ring just OUTSIDE its bounding box. For an element that paints its OWN opaque background (a caption pill, a CTA button, a solid card), the text is composited over that solid color, not over whatever surrounds the box. Sampling the ring there measured the text against the scene behind the element (often a dark photo), producing false ~1:1 ratios and flagging perfectly readable CTAs and captions. Users reported the warning persisting no matter how they changed the background color, because the audit was never reading it. Resolve the nearest fully-opaque background-color by walking the element up its ancestor chain, and use it when present; keep sampling the ring only when the text sits over image pixels (a background-image is hit first) or no opaque background exists. The pure decision lives in a new commands/contrast-bg.ts with unit tests; contrast-audit.browser.js (injected as a raw string, so it cannot import) inlines the same logic, mirroring the existing duplicated-WCAG-math note. |

fix(cli): exclude clip-path-hidden text from inspect layout and contrast audits (#1821)
* fix(cli): exclude clip-path-hidden text from inspect layout and contrast audits A clip-path can shrink an element's painted region to nothing (a typewriter span pre-reveal at clip-path: inset(0 100% 0 0), or circle(0px)) while its layout box, opacity, visibility and display all still read as present. Such an element paints zero pixels, so the layout audit flagged the visible block beneath it as a content_overlap, and the contrast auditor measured it as a meaningless background-on-background ratio (~1:1) and reported a WCAG failure. Both auditors already filtered opacity:0, visibility:hidden and display:none, but neither accounted for clip-path. Add a shared check: when a non-none clip-path is in effect on the element or an ancestor, probe a grid of points across the element's box with elementFromPoint; if none resolve to the element or a descendant, it is clipped to nothing and is skipped. The probe runs only when a clip-path is present, so a genuinely occluded (but unclipped) element is still measured and still flagged. Wired at the in-page collection chokepoint so it covers content_overlap, text_occluded and the contrast auditor consistently. Genuine overlaps between visible elements remain flagged; data-layout-allow-overlap and data-layout-ignore are honored unchanged. The two audit scripts and the layout-audit test are added to the fallow ignore lists: their pre-existing IIFE-level complexity and per-rule test scaffold re-flag under the line-shift fingerprint when the small probe helpers are inserted. * test(cli): cover clip-path audit edge cases * fix(cli): satisfy clip audit test types |

feat(skills): product-launch-video skill + consolidate motion knowledge into hyperframes-animation (#1745)
* feat(skills): product-launch-video + consolidate motion knowledge into hyperframes-animation
- Add the product-launch-video skill: shot-sequence architecture where each
visual frame is a time-coded shot sequence picked from a blueprint menu and
paced to the voiceover (anti-PowerPoint). Includes the frame-worker sub-agent,
story/visual/motion-design references, and audio/captions/transitions/
stage-assets/assemble-index scripts.
- Consolidate motion knowledge in hyperframes-animation as the single source of
truth: promote the updated atomic rules (31 -> 36) and rename product-launch-
video's archetypes into hyperframes-animation blueprints (13 -> 15, replacing
the old set). product-launch-video, faceless-explainer, and pr-to-video now
reference them via ../hyperframes-animation/{rules-index,blueprints-index}.md
and the rules/blueprints dirs. Fixes the discrete-text-sequence broken links;
blueprints no longer ship per-id runnable examples, so example references in
the consumers were dropped.
- Default HeyGen TTS voice to Marcia (deterministic; was the API's first English
voice, which drifts on catalog re-sort). Override with --voice.
- assemble-index pre-assembly frame guards: auto-repair a sub-comp root missing
canvas dims; hard-fail on <video>/<audio> inside a sub-comp; hard-fail on a
timed non-root element missing class="clip" or overlapping same-track clips.
- Lint/CLI: lint media inside sub-compositions as an error; stop false-positive
caption layout/lint findings; contrast/layout-audit skip elements hidden by an
invisible ancestor.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* fix(skills): clear CodeQL alerts in assemble-index.mjs
- script/style blanking regex now matches closing tags with trailing
whitespace (</script >, </style >) — js/bad-tag-filter (high).
- drop the existsSync precheck before reading/repairing a frame file; read
directly and handle ENOENT, removing the check->write TOCTOU window —
js/file-system-race (high).

fix: harden CLI edge-case repros (#591)
## Problem I reproduced the selected open issue batch one by one and confirmed the reports were valid. The fixes all touch the CLI/runtime capture boundary, then the follow-up regression run exposed one over-broad runtime change in sub-composition host visibility and one CI-only baseline trap. Closes #590, #589, #588, #587, #586, and #584. ## What this fixes ### CLI/runtime edge cases - Makes the GSAP infinite-repeat lint rule ignore JavaScript comments, so literal `repeat:-1` text in comments is not flagged. - Lets the compositions CLI inspect `<template>` content, count visual-only template descendants, estimate simple GSAP durations, and suppress root `data-start` warnings in sub-composition lint mode. - Preserves runtime bootstrap scripts when body scripts are coalesced, and injects the runtime into a real `<head>` when source HTML has no head. - Keeps #589 fixed by loading and rendering template-wrapped sub-composition content, while restoring host visibility to the shorter of the authored parent clip window and the child composition live timeline. - Resolves snapshot/validate viewport size from root `data-width` / `data-height` instead of falling back to 1920x1080. - Skips fully off-frame text boxes during contrast sampling and bounds-checks ring samples so contrast output no longer emits `null:1` / `NaN:1`. - Marks muted videos as `data-has-audio="false"` in the core timing compiler, which fixes the same-src muted `<video>` + separate `<audio>` StaticGuard case. - Keeps user-authored `hf-seek` listeners reachable during capture by preventing author scripts from being merged into the runtime bootstrap path. ### Shared helper cleanup - Removes the stale producer-local timing compiler duplicate; producer compilation now consumes the core timing compiler. - Centralizes HTML document helpers in core: fragment parsing, embedded runtime stripping, head/body script injection, and early-head injection. - Centralizes the CLI layout/snapshot static HTML server. - Adds browser-safe core subpath helpers for Lottie readiness and CLI screenshot clip calculation; Studio's Vite config keeps the screenshot clip helper self-contained so clean-checkout test startup does not value-import core `.ts` source. - Replaces the engine parity-contract copy with a core re-export. - De-duplicates render-job cleanup and Studio static file-serving callbacks. ### Regression hardening - Replaces the embedded-runtime script stripping regex with a script-tag scanner that handles closing tags like `</script >`. - Escapes inline script bodies before wrapping them in `<script>` tags, so authored `</script` and `<!--` text cannot break out of the injected wrapper script. - Shares media-duration clamping between core and producer, with a 50 ms tolerance for ffprobe precision drift between local and CI media stacks. - Pins the affected style fixture SFX durations in source so style-1 and style-9 compile deterministically. - Restores the `vfr-screen-recording` video golden to the CI-stable baseline; the current CI failure showed the Linux render matches the old golden, while the locally refreshed macOS golden was the mismatch. ## Root cause The CLI paths had accumulated assumptions that held for simple direct-root landscape compositions but not for current composition patterns: DOM queries did not enter template content, snapshot/validate used a fixed viewport, runtime and author scripts shared a coalescing bucket, and timing compilation treated every video as audio-bearing unless authors manually overrode it. The style shard failures were not product regressions. Local and CI media probing disagreed on the short SFX clip duration by about 45 ms, and the compiler was clamping authored durations to the locally probed value. The shared clamp tolerance preserves explicit author/source durations for small probe precision differences while still clamping real overflows. The vfr fast-shard failure was a bad baseline refresh: CI actual frames matched the old `vfr-screen-recording` baseline at 40+ dB PSNR, but mismatched the macOS-refreshed golden at ~18-22 dB. The fix is to keep the Docker/Linux-stable video golden and only retain the deterministic compiled snapshot change. The sub-composition regression came from treating a host's authored parent window as the only visibility boundary. That made settled child overlays stay visible after their own live GSAP timeline ended. The corrected runtime behavior respects both contracts: parent clips still bound where the host can appear, and the child live timeline can end the host earlier. ## Verification ### Local checks - `bunx oxfmt --check packages/core/src/runtime/init.ts packages/core/src/runtime/init.test.ts` - `bunx oxlint packages/core/src/runtime/init.ts packages/core/src/runtime/init.test.ts` - `bun run --cwd packages/core test src/runtime/init.test.ts` - `bun run --cwd packages/cli test src/commands/compositions.test.ts src/utils/compositionViewport.test.ts` - `bun run build:hyperframes-runtime` - `bun run --cwd packages/producer test --keep-temp --sequential style-12-prod style-5-prod` - `bun run --cwd packages/producer test --sequential vfr-screen-recording hdr-hlg-regression style-7-prod` - `bun run --cwd packages/core test src/compiler/htmlCompiler.test.ts src/compiler/timingCompiler.test.ts src/index.test.ts` - `bunx oxfmt --check packages/core/src/compiler/timingCompiler.ts packages/core/src/compiler/htmlCompiler.ts packages/core/src/compiler/htmlCompiler.test.ts packages/core/src/compiler/index.ts packages/core/src/index.ts packages/core/src/index.test.ts packages/producer/src/services/htmlCompiler.ts` - `bunx oxlint packages/core/src/compiler/timingCompiler.ts packages/core/src/compiler/htmlCompiler.ts packages/core/src/compiler/htmlCompiler.test.ts packages/core/src/compiler/index.ts packages/core/src/index.ts packages/core/src/index.test.ts packages/producer/src/services/htmlCompiler.ts` - `bun run --cwd packages/core typecheck` - `bun run --cwd packages/producer typecheck` - `bun run --cwd packages/producer test --sequential style-1-prod style-9-prod` - `bun run --filter @hyperframes/studio test` with `packages/core/dist` temporarily hidden to simulate clean-checkout config loading - `git diff --check` ### CI artifact checks - Inspected failed run `25225854394` job `73969147096`: style-1 failed only on `click-sfx` `1.044898` vs `1` duration/end. - Inspected failed run `25225854394` job `73969147061`: style-9 failed only on SFX `1.044898`-based duration/end mismatches. - Inspected failed run `25225854394` job `73969147048`: `vfr-screen-recording` compilation/audio passed, visual failed after comparing against the macOS-refreshed golden. - Compared the first 10 uploaded CI vfr failure frames against the restored old baseline; minimum PSNR was `40.444705`, above the fixture threshold of `28`. ### Repro checks - `bun packages/cli/src/cli.ts lint /tmp/hf-590-repro` now passes without `gsap_infinite_repeat`. - `bun packages/cli/src/cli.ts snapshot /tmp/hf-587-repro --at 0.5 --timeout 1000` now writes a 1080x1920 PNG. - `bun packages/cli/src/cli.ts validate /tmp/hf-588-repro --timeout 500` no longer emits `null:1` / `NaN:1` contrast output. - `bun packages/cli/src/cli.ts validate /tmp/hf-586-repro --timeout 500 --contrast false` no longer emits the muted-video StaticGuard contract error. - `bun packages/cli/src/cli.ts compositions /tmp/hf-589-gsap-repro` now reports `foo 0.5s 1920x1080 1 element`. - `bun packages/cli/src/cli.ts snapshot /tmp/hf-589-gsap-repro --at 0.25 --timeout 2000` captures the expected template-backed red frame. - `bun packages/cli/src/cli.ts snapshot /tmp/hf-584-repro --at 0.5,1.5 --timeout 500` captures the expected post-seek green frame. ### Browser verification - Refreshed the local side-by-side comparison page at `qa-artifacts/pr-591-video-compare/index.html`. - Served the comparison page locally and used `agent-browser` to load `style-12-prod`, play both videos quickly to the failed window, pause, and inspect the side-by-side frame. - Browser proof screenshot: `qa-artifacts/pr-591-video-compare/browser-proof/fixed-style12-labeled.png`. - Browser proof recording: `qa-artifacts/pr-591-video-compare/browser-proof/fixed-style12.webm`. - Earlier Studio proof artifacts remain local-only: `qa-artifacts/dedupe-refactor-preview.png`, `qa-artifacts/dedupe-refactor-preview-after-play.png`, `qa-artifacts/dedupe-refactor-preview.webm`. ## Notes - Browser proof and CI diagnostic artifacts are intentionally local-only and not committed. - Studio's Vite config intentionally keeps the thumbnail clip helper inline because Vite/Vitest config startup runs through Node's loader before package source `.ts` imports are transformed. - The committed PR diff changes `vfr-screen-recording/output/compiled.html` but no longer changes `vfr-screen-recording/output/output.mp4` relative to `main`. - I attempted a local `linux/amd64` Docker validation to mirror CI, but the local Docker build was blocked by Debian package download failures. The arm64 Docker image also cannot launch the x64 Puppeteer headless shell under OrbStack. The vfr baseline decision is therefore based on the uploaded CI artifact comparison above. - I kept this validated issue batch in one PR because the fixes overlap the same CLI/runtime capture surfaces. |

fix(skills): correct README skills table and move orphaned scripts into hyperframes skill (#282)
## What Fixes the README skills table to match actual skill names, and moves two orphaned script directories into the `hyperframes` skill where they belong. ## Why **README**: Listed `hyperframes-compose` and `hyperframes-captions` as separate skills — these don't exist. Captions/compose are part of the `hyperframes` skill. Also listed `gsap-core, gsap-timeline, gsap-plugins, ...` but the actual skill is just `gsap`. Missing `hyperframes-cli` entirely. **Orphaned scripts**: `skills/hyperframes-animation-map/` and `skills/hyperframes-contrast/` had scripts but no `SKILL.md` — they looked like broken skills and wouldn't be installed by `npx skills add`. They're helper scripts invoked by the main `hyperframes` skill (SKILL.md already references them in the "Quality Checks" section). Moving them under `skills/hyperframes/scripts/` makes them part of the skill they belong to. ## How **README skills table** — corrected to match the 4 actual skills: - `hyperframes` (was `hyperframes-compose` + `hyperframes-captions`) - `hyperframes-cli` (was missing) - `hyperframes-registry` (unchanged) - `gsap` (was `gsap-core, gsap-timeline, gsap-plugins, ...`) **Script moves:** - `skills/hyperframes-animation-map/scripts/animation-map.mjs` → `skills/hyperframes/scripts/` - `skills/hyperframes-contrast/scripts/contrast-report.mjs` → `skills/hyperframes/scripts/` - Removed empty `skills/hyperframes-animation-map/` and `skills/hyperframes-contrast/` - Updated path references in SKILL.md, both script headers, and `contrast-audit.browser.js` ## Test plan - [ ] `grep -r "hyperframes-animation-map\|hyperframes-contrast" --include="*.md" --include="*.mjs" --include="*.js" --include="*.ts" .` returns no results - [ ] `ls skills/` shows only `gsap`, `hyperframes`, `hyperframes-cli`, `hyperframes-registry` - [ ] README skills table matches `skills/*/SKILL.md` names - [x] Documentation updated (if applicable) |

feat(skills): add contrast audit + animation map quality skills (#267)
## Summary
Two new quality skills + CLI integration that give agents feedback loops they currently lack — pixel-level contrast auditing and structured animation analysis.
### What this unlocks for agents
**Agents can now catch accessibility failures that humans and LLMs consistently miss.** The contrast audit runs automatically on every `hyperframes validate` and reports WCAG AA violations as warnings. In the eval, 4 out of 5 palettes had failing contrast — every baseline composition shipped broken, every treatment composition caught and fixed it.
**Agents can now reason about animation choreography.** The animation map produces a structured JSON report with:
- Per-tween natural language summaries ("card1 slides 23px up over 0.5s, fades in, ends at (120, 200)")
- ASCII timeline showing the full choreography as a Gantt chart
- Stagger detection with actual intervals ("3 elements stagger at 120ms" — validates against brief specs)
- Dead zone detection (periods >1s with no animation — missing entrance or intentional hold?)
- Element lifecycles (first/last animation, final visibility — catches elements that enter but never exit)
- Scene snapshots at 5 timestamps (what's on screen at any moment)
### Changes
**Skills (new)**
- \`skills/hyperframes-contrast/\` — WCAG contrast audit skill + script
- \`skills/hyperframes-animation-map/\` — animation analysis skill + script
**CLI**
- \`hyperframes validate\` now runs contrast audit by default (warnings, not errors)
- \`hyperframes validate --no-contrast\` to skip
- \`hyperframes render --html-only\` compiles HTML without video encoding
- Browser-side WCAG code in \`contrast-audit.browser.js\`, inlined at build time via esbuild text loader
**Producer**
- Exported \`compileForRender\` for the \`--html-only\` flag
### Eval results
5 prompts x 2 arms = 10 compositions. Arm A = baseline skills. Arm B = +contrast +animation-map.
| Prompt | Failing color | Before | After |
|--------|--------------|--------|-------|
| Halflife | Cement on Ink | 2.98:1 | 5.33:1 |
| Meridian | Ash on Midnight | 2.08:1 | 5.44:1 |
| Typesmith | Pencil on Paper | 3.19:1 | 5.50:1 |
| Lattice | Gray-600 on Terminal | 2.59:1 | 7.50:1 |
Animation map correctly enumerated 142 tweens across 5 compositions, detected stagger groups, flagged pacing issues, and produced scene snapshots.
