miga-heygenandMiguel Ángel 3704863d96 feat(telemetry): per-tag, provenance, and failure-taxonomy properties on render events (#4004)
* feat(telemetry): add per-tag element and a-roll counts to render_complete

countElementTags's single regex scan (the ~83% of renders that get no
live probe session) is extended into scanElementTags, which returns a
per-tag breakdown and an a-roll video count alongside the same total,
all from one pass over the same script/style-stripped markup — the
total is the sum of the per-tag map by construction, so the two
properties can't drift apart. countElementTags itself is removed; it
had zero production callers after this change.

New render_complete properties: composition_element_tags ({tag: count},
raw lowercase tag names, capped at the top 50 by count with the rest
folded into an "other" key) and aroll_video_count (<video
data-aroll="true"> elements from the same scan). Both are static-scan-
only, mirroring the existing composition_element_count_source split —
the live probe-DOM path never runs this scan.

* feat(telemetry): count HeyGen-provenance video from the same tag scan

heygenVideoCount joins arollVideoCount/byTag as a third property
derived from scanElementTags's single pass: <video
data-media-source="heygen"> elements. media-use's resolve.md now
documents that the skill stamps this attribute on a mounted video only
when the ledger record's provider is "heygen.video" (the mount itself
is always the agent's own composition edit, never written by resolve
scripts) — the ledger stays the single source of truth for provenance,
the HTML attribute is a projection of it, and no other provider value
is invented beyond this one signal.

* feat(telemetry): add a bucketable failure taxonomy to render_error

error_name (error.name, e.g. one of the ~20 typed producer error
classes) and failed_stage_code (job.currentStage/failedStage
normalized to a stable snake_case code via normalizeStageCode)
join the existing free-text error_message/failed_stage, so a fleet
query can bucket failures without parsing prose. Error-conditional by
nature — render_complete has no equivalent, since a successful render
has no error to name or stage to blame.

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: http://localhost:3002/#project/my-video
# Server: http://localhost:3002

npx hyperframes preview --port 4567

In an interactive terminal, the preview stays attached until you press Ctrl+C. In a non-interactive shell such as a coding-agent session, the same command starts a managed preview that survives after the command returns. Use --background or --foreground to choose explicitly, and manage persistent previews with --status, --stop, --list, and --kill-all. Add --json to managed lifecycle commands for machine-readable output. --foreground --json prints the ready-session envelope once, then remains attached until stopped.

normalize-audio

Measure two local authored audio clips with integrated LUFS and match the target to the unchanged reference. The command is a dry run unless --write is passed:

npx hyperframes normalize-audio --reference target-audio --target user-audio
npx hyperframes normalize-audio --reference target-audio --target user-audio --write

It updates only the target element's data-volume and refuses unsafe boosts that exceed Studio's +12 dB ceiling or would clip.

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

Set HYPERFRAMES_RENDER_DETACHED=1 when starting a render with nohup or disown so it keeps running after the invoking shell exits.

publish

Upload a project directory and get a hosted URL that keeps working after the CLI exits. Published projects are private by default:

npx hyperframes publish
npx hyperframes publish ./my-video
npx hyperframes publish --public
npx hyperframes publish --yes

Signed-out publishing returns an authentication-required claim URL; opening it lets someone sign in and claim the project. Sign in first with npx hyperframes auth login to publish an owned project you can update. Use --public to make the claimed project visible to anyone. --yes only skips the confirmation prompt and does not change visibility.

Signed-in publishers can use --update <url-or-id> to target an existing project or --space <space-id> to publish into a shared team space. If the requested project is missing or inaccessible, publishing can create a new project instead; check the printed URL and status.

See the publish reference for all options, including video proxy settings.

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
