WaterrrForever b9be0b2625 feat(skills,studio,media-use): the intent layer, review loop, and user memory — BRIEF.md, companion mode, recipes; /website-to-video folds into /product-launch-video (#2133)
* feat(studio,cli): per-frame board comments, self-refreshing storyboard, status-aware preview landing

Per-frame comment boxes on the storyboard board batch into
.hyperframes/frame-comments.json (a resubmit wins per frame; unconsumed
comments on other frames are kept). Submitted-but-unconsumed comments
stay visible — a toolbar banner plus a per-tile echo — until the agent
consumes the file; the banner also says what to do next (reply anything
in the agent chat).

The board keeps itself current: GET /projects/:id/signature exposes the
watcher-cached project signature, the storyboard payload carries the
signature it was derived from, and the view polls at 2s (hidden tabs
skipped, re-checked on visibility), refetching in place with no loading
flash. Posters bake the signature into their URL so tiles fill in as
sketches land and a poster that failed mid-write retries on the next
version; the empty state upgrades itself when STORYBOARD.md appears,
and its handoff prompt now points the agent at the review loop and uses
the parser's real status vocabulary (outline, not planned).

preview lands the browser on the storyboard view while the board is the
review surface — any frame built, or pure planning (srcs declared, none
on disk yet) — and on the timeline once the video is assembled.

* feat(skills): the review loop — plan, sketch, build as one shared process

hyperframes-core/references/review-loop.md is the single source for the
three-pass collaborative review: the plan proposed on a live board
(§ 1), wireframe sketches marked built with one layout question (§ 2 —
real words on plain blocks, run no CLI; a confirmed board is itself a
valid deliverable when the user asked for a storyboard, not a video),
the build dressing confirmed layouts (§ 3, worker or inline), and the
final look (§ 4). Autonomous runs skip every gate and keep one question
before render.

The three narrative workflows' Steps 3/4/6 collapse to references plus
their sketch stand-ins (captured-asset blocks for product-launch-video,
plain code panels for pr-to-video); the confirmed-sketch handoff stays
in each frame-worker prompt. general-video plans on a board for
multi-scene narrative pieces in collaborative mode — its sketch pass is
layout-before-animation with the user watching. The router treats
"I want a storyboard" as a process request rather than a route, and
closes exploratory intake by recommending a route plus how the run will
review.

The supporting contracts land next door: the comments channel (silent
submit, one reply picks it up, check the file before the words) in
brief-contract § 1; the sidecar schema and the built status rung in
storyboard-format; the mode question asked first and alone in the three
workflows' Step 0.

* feat(media-use): user memory — remembered preferences and frozen recipes

Two tiers of memory on media-use's existing two-tier storage split.

Preferences (lightweight): confirmed brief answers — destination, aspect,
language, mode, voice, style preset — recorded to the project's
.media/preferences.json (committed, the team inherits it) and promoted
to the personal ~/.media/preferences.json once the same value is
confirmed in two different projects (a sightings ledger accumulates the
cross-project evidence user-side, since project files can't see each
other). prefs.mjs get/record; merge reads project-over-user; a changed
value restarts its provenance.

Recipes (heavyweight): one approved run frozen as a named, versioned
bundle — frame.md, the storyboard skeleton (structure kept: durations,
transitions, srcs, Video direction; statuses reset to outline; content
blanked to per-frame fill-ins naming the beat's role), and the confirmed
brief values. Named folders, not content hashes: re-freezing bumps
version and archives <name>@v<N>; a freeze is already confirmed, so it
promotes to the user tier immediately. recipe.mjs freeze/list/use, plus
resolve --type recipe --entity <name> delegating like grade/lut.

16 new node --test cases; the media-use lib suite is 168/168.

* feat(skills): wire user memory into the brief and the review loop

brief-contract § 2 gains Remembered defaults: read the merged
preferences before Round 2 and let a remembered value become the
recommended option with a receipt naming its source project. Memory
changes the default, never the question — every ask-marked field still
gets asked, and what the request says this time beats what was picked
last time. Record only what the user actually confirmed (a defaulted
voice nobody chose is not an answer; a "go" that accepts the
recommended defaults is). The first record announces itself once;
after that the receipts carry the reminder. In autonomous mode a
remembered value becomes the decided value, receipt included.

The three narrative workflows read the remembered defaults before
Round 2, record the confirmed answers at the Step 0 gate, record the
chosen preset at the Step 2 gate (pr-to-video excepted — its preset is
fixed), and fall back to the remembered voice when the request names
none. general-video's discovery reads the same defaults.

Recipes wire in at both ends: Step 0 checks for a matching recipe
before the mode question — one question, plural-aware, and adopting
one fills the brief, skips the design step, and drafts the storyboard
from the frozen skeleton while every review gate still runs. The
review loop's final look (§ 4) offers the freeze once after approval,
and the confirmation teaches the recall phrase — the name is something
the system reminds the user of, never something they must remember.
The router recognizes a named recipe or "like last time" as a route.

* docs(skills): the sketch pass names check, not the deprecated validate

* feat(skills): intent-layer references — process, route briefs, capability menu, BRIEF.md format

* feat(media-use): brief skeleton as the recipe's fourth artifact; flow/storyboard preference keys

* feat(skills): the intent layer conducts every brief — workflows execute BRIEF.md

* feat(skills): retire the mode preference key; sync catalog surfaces for intent layer

* refactor(skills): dedupe router vs intent-layer guidance — one owner per rule

* feat(skills): the design ask — own spec, pick by eye from showcases, or defer

* docs(skills): the design ask says the honest line on capture routes

* feat(skills): product-launch-video absorbs website-to-video as the tour angle

* refactor(skills): keep product-launch-video pristine — a tour is brief intent, not a pipeline branch

* feat(skills): production loop + genre lenses; general-video goes freeform (route yours, laws hold)

* refactor(skills): /hyperframes is the front door - route tables and scope lists leave the workflows

* docs(skills): review-loop pass across skill catalog

* fix(cli): pass project dir to openStudioBrowser in background-server path

* feat(skills): add pitch-round reference - verbalized sampling concept gate

* feat(skills): wire pitch round into intent layer - completeness triage + route eligibility

* feat(skills): editorial capability recommendations, handoff disciplines, menu-probe split

* feat(skills): pitches carry their machinery; source-only-formed requests pitch the telling

* feat(skills): companion goes director - ceiling treatment plus blueprint/rule citation discipline

* fix(scripts): sandbox npx-leak guard - private npm global prefix keeps npx on the branch CLI

* chore(skills): resync manifest hash after formatter pass reflowed general-video tables

* fix(skills): recipe freeze reads workflow from BRIEF.md; style_preset records require workflow scope

Two holes found by a live companion-run freeze: the agent-supplied --workflow
contradicted the run's actual workflow (recipe.json said faceless-explainer,
brief-skeleton said general-video), and the style_preset lookup missed because
the preference had been recorded under the bare key.

- freezeRecipe resolves the workflow from BRIEF.md frontmatter; the flag is a
  fallback for briefless projects and a contradicting flag is ignored (noted).
- recordPreference refuses a bare style_preset — the scoped key is the only
  writable shape; freeze tolerates legacy bare records via read fallback.
- review-loop § 4 / media-use SKILL / brief-format wording follow the machinery.

Data Attributes Reference

Every HyperFrames composition uses data-* attributes to declare timing and structure to the framework. This is the full attribute table — pair with tracks-and-clips.md for the rules behind data-track-index.

Composition Root

Every renderable composition needs one root element:

Attribute Required Meaning
data-composition-id Yes Unique ID. Must match the animation registry key on window.__timelines.
data-width / data-height Yes Pixel frame size. Common values: 1920x1080, 1080x1920, 1080x1080.
data-duration Conditional* Render duration in seconds (total length / frame count), not the GSAP timeline length. Read once at compile time, like data-width / data-height: a static root data-duration is locked before scripts run, so a script (root.setAttribute("data-duration", ...)) or a --variables-driven value cannot change the render length. To vary length per render, author the root data-duration directly. (A clip's data-duration is different: re-read from the live DOM, so scripts/variables can drive it.) Only when the root omits data-duration does the renderer derive total length from the live DOM / timeline after scripts run.
data-fps No Optional frame rate hint. CLI render flags can override output fps.
data-composition-variables No JSON array of variable declarations (on <html>). See variables-and-media.md.

*data-duration is optional whenever the runtime can auto-infer duration: a registered GSAP timeline, a finite CSS animation, a finite WAAPI element.animate(), or a registered Lottie animation. It is required for Three.js (no auto-inference), for infinite/unbounded CSS or WAAPI animations, and for any composition with no GSAP timeline and no animation signal at all. npx hyperframes lint enforces this (root_composition_missing_duration_source). See determinism-rules.md → "Duration Contract For Non-GSAP Runtimes" for the per-runtime breakdown.

The root should be position: relative, have explicit pixel dimensions, and hide overflow unless intentionally composing outside the frame.

Clip Attributes

Timed child elements are clips. class="clip" is required on visible timed elements (<div>, <img>, etc.) — without it the runtime keeps the element visible for the whole composition, ignoring data-start / data-duration. Omit on <video> (framework manages visibility directly) and <audio> (no visual).

Clips must be DIRECT children of the composition root. A clip nested inside a wrapper <div> is not registered — most visibly, a <video> in a wrapper is never seeked/decoded and renders black. To wrap/transform a clip, put the wrapper inside the clip, or animate the clip element itself; do not wrap the clip. (<video>/<audio> additionally must be at the host root, never in a sub-comp <template> — see variables-and-media.md.)

Attribute Required Meaning
id Yes Stable DOM ID for linting, timeline targets, and debugging.
data-start Yes Start time in seconds, or a supported clip-time reference.
data-duration Required for div, img, and sub-compositions Duration in seconds. Video/audio can default to media duration when known.
data-track-index Yes Timeline track. Clips on the same track must not overlap.
data-media-start No Offset into the media source, in seconds.
data-volume No Static audio volume, 0 to 1, default 1. For fades, animate volume on the timeline instead (see variables-and-media.md).
data-has-audio No (<video> only) "true" to declare the video carries an audio track when auto-detection would miss it.

Visibility window is inclusive of both ends. A clip shows while start ≤ t ≤ start + duration — it still renders at exactly t = start + duration, so the final frame holds the animation's resolved end state (the runtime does not hide it one frame early). A reveal/entrance that lands on data-duration is therefore visible on the last frame; you do not need to finish it before data-duration just to guarantee the end state renders. (Climax-dwell guidance in /hyperframes-animation is about pacing, not this boundary.)

Sub-Composition Host Attributes

When a clip is a sub-composition host (loads another composition file):

Attribute Required Meaning
data-composition-id Yes The internal composition ID of the loaded file.
data-composition-src Yes Path to the sub-composition HTML file.
data-width / data-height Yes Render dimensions for the sub-composition instance.
data-variable-values No Per-instance variable overrides as JSON. See variables-and-media.md.
data-var-src No Binds the element's src to a declared variable id (media/image substitution, authored src = fallback).
data-var-text No Binds the element's own text to a scalar variable id; children are preserved.

See sub-compositions.md for the full wiring pattern.

Authoring Hints

  • id="root" — template convention used by scaffolds and the transition catalog so CSS can target the composition root with #root instead of [data-composition-id="main"]. Not required by the runtime, but consistent with the rest of the ecosystem.
  • class="clip" — required runtime visibility marker on visible timed elements (<div>, <img>, …). See Clip Attributes above.
  • data-layout-allow-overflow — tells hyperframes check that overflow on this element (or its descendants) is intentional. Notes:
    • The check layout audit measures getBoundingClientRect at sampled timestamps, not rendered pixels. overflow: hidden clips the visual but does not suppress a layout finding. This attribute is the escape hatch; CSS overflow is not.
    • Can be set on the composition root as well as on any child. When the cited offender is div.<comp>-root inside div.<comp>-root (the root reports its own children's union as overflowing), the fix goes on the root, not on individual text descendants — shrinking font sizes will not converge.
    • In a multi-scene group_wN.html (continue runs), every scene-local element stays in the DOM during the other scenes' time windows; the layout-box union almost always overflows the canvas during morph seams. Mark the root and every scene-local primary/supporting element with this attribute at construction, not after check flags it.
    • Blast radius — it silences more than the overflow audit. The attribute is inherited down the subtree (the perception probe walks ancestors), so it also suppresses the rendered-perception checks text-clipping, content-cramped-container, and foreground-over-panel for every descendant. Putting it on a persistent panel that also hosts real foreground content disables collision checks on that content for the panel's whole lifetime. Prefer the narrowest opt-out: scope it to the smallest decorative wrapper, or use per-element data-layout-bleed="true" for one intentional primary-text crop. The two canvas/edge checks primary-offscreen and foreground-over-panel deliberately run even under allow-overflow, so it cannot hide a wordmark sliced by the frame or text bleeding onto a panel edge.
  • data-layout-ignore — exclude this element from layout audits entirely.
