Xuanru LiandClaude Fable 5 3e3b37d37f fix(cli): occlusion-probe false positives — pointer-events blindness, low-alpha gradients, not-yet-entered text (#2357)
* fix(cli): three occlusion-probe false-positive sources in text_occluded

- pointer-events:none text is invisible to elementFromPoint, so the probe
  always hit whatever paints beneath and misread visible text as buried;
  restore hit-testing on the element for the duration of the probe
- a backgroundImage counted as opaque regardless of alpha, so a 4%-alpha
  grid/scrim gradient qualified as an occluder; gradients now occlude only
  when their colours reach alpha > 0.6 (url() images unchanged)
- a visible container whose every text-bearing descendant is still at
  opacity 0 (entrance not started) was probed anyway; skip when no text
  ink is on screen

* fix(cli): address review — document-wide hit-testing restore, gradient compositing, whitespace ink

- restore hit-testing for ALL pointer-events:none elements during the text
  audit pass (not just the probed text): an occluder that itself carries
  pointer-events:none is invisible to elementFromPoint, which made truly
  buried text read as clean once the text alone became hittable
- hasVisibleTextInk ignores whitespace-only text nodes (indented markup
  defeated the gate) and uses a 0.05 floor so mid-fade text keeps its
  persistence occurrences
- hasOpaqueBackground composites gradient alpha with background-color
  (two 0.5-alpha layers paint at ~0.75); gradientMaxAlpha returns opaque
  for any colour function it cannot score (oklch/lab/...); percentage
  alpha values now parse as fractions

* fix(cli): walk the elementsFromPoint stack in occluderAt

A transparent layer that becomes hittable (pointer-events restored) must
not mask an opaque occluder painting beneath it — single-point
elementFromPoint returned the transparent top and dropped two genuinely
buried cases in the census acceptance run; the stack walk keeps 10/10.

* fix(cli): composite stacked background-image layers when judging occluder opacity

Two 0.5-alpha gradient layers paint at 0.75 combined; taking the max
color-stop alpha across the whole declaration under-counted them and
suppressed real text_occluded findings. Split layers at top-level commas
(paren-aware), score each, composite as 1-prod(1-a_i). Also pins the
0.05 text-ink floor with a boundary test (review feedback on #2357).

* fix(cli): keep walking the occlusion stack past pair-specific exemptions

sharedPreserve3d and isCrossSceneTransitionOverlap excuse one hit, not
the whole probe; returning null let a transparent decorative layer in
the text's 3D context mask a real occluder below it (review feedback).

hyperframes

CLI for creating, previewing, and rendering HTML video compositions.

Install

npm install -g hyperframes

Or use directly with npx:

npx hyperframes <command>

Requirements: Node.js >= 22, FFmpeg

Commands

init

Scaffold a new Hyperframes project from a template:

npx hyperframes init my-video
cd my-video

preview

Start the live preview studio in your browser:

npx hyperframes preview
# Studio running at http://localhost:3002

npx hyperframes preview --port 4567

render

Render a composition to MP4. Run from the project directory; the positional argument is the project directory (not a file), so render the project's index.html directly, or point at a specific composition file with -c:

npx hyperframes render -o output.mp4
npx hyperframes render -c ./my-composition.html -o output.mp4

lint

Validate your Hyperframes HTML:

npx hyperframes lint ./my-composition
npx hyperframes lint ./my-composition --json      # JSON output for CI/tooling
npx hyperframes lint ./my-composition --verbose   # Include info-level findings

By default only errors and warnings are shown. Use --verbose to also display informational findings (e.g., external script dependency notices). Use --json for machine-readable output with errorCount, warningCount, infoCount, and a findings array.

compositions

List compositions found in the current project:

npx hyperframes compositions

benchmark

Run rendering benchmarks:

npx hyperframes benchmark ./my-composition.html

doctor

Check your environment for required dependencies (Chrome, FFmpeg, Node.js):

npx hyperframes doctor

browser

Manage the bundled Chrome/Chromium installation:

npx hyperframes browser

info

Print version and environment info:

npx hyperframes info

docs

Open the documentation in your browser:

npx hyperframes docs

upgrade

Check for updates and show upgrade instructions:

npx hyperframes upgrade
npx hyperframes upgrade --check --json  # machine-readable for agents
