The missing_three_script rule only treated a bare import from 'three' as
loading Three.js, so ESM imports whose specifier is a URL or path (e.g.
.../+esm CDN builds, esm.sh/three, unpkg three.module.js, or a local
three.module.js) were not recognized. Compositions using THREE. with such
an import got a false blocking error, pushing authors onto the deprecated
UMD global build.
Generalize the module-import detection to count any import/from whose
specifier contains "three" (case-insensitive), matching the existing
loose /three/i treatment of <script src>. Bare 'three', importmap, and
<script src> paths are unchanged; the specifier must still contain
"three", so unrelated imports do not satisfy it.
The font_family_without_font_face rule raised a blocking error on two
legitimate, very common cases:
1. The `-apple-system, BlinkMacSystemFont` system-ui stack. These two
tokens are the cross-browser incantation for the platform UI font
(synonyms of `system-ui`); they name no font file, so demanding an
@font-face for them is wrong. They appear in almost every CSS reset.
2. `font-family: var(--x)` indirection. The shared family extractor took
the literal `var(--heading)` as a font name. The linter cannot
statically resolve a custom property, so it must not flag it.
Fix at the root: add the two system-ui synonyms to GENERIC_FAMILIES, and
skip any parenthesised (function) token in the shared family extractor so
both this rule and system_font_will_alias stop misreading var(). A real
undeclared font sitting in the same stack is still flagged.
* fix(lint): stop overlapping_gsap_tweens flagging distinct unresolved targets
The GSAP parser assigns the sentinel `__unresolved__` to any tween whose
target it cannot statically resolve to a concrete element (a computed
variable, a helper call, etc.). The overlap check compared tweens by that
target string, so two tweens aimed at completely different elements via
unresolvable selectors (e.g. `#s0 .hl .w` and `#s1 .hl .w` produced by a
helper) both collapsed to `__unresolved__` and were reported as
overlapping, a false positive.
An unresolved target is an unknown element: two of them are not provably
the same element, so an overlap between them cannot be asserted. Skip
overlap analysis when the target is the sentinel. Genuine overlaps on a
resolved element are still flagged.
* fix(lint): guard gsap_exit_missing_hard_kill against the unresolved-target sentinel
The overlap rule already skips tweens whose target collapses to the
__unresolved__ sentinel, but the sibling exit rule in the same file did not.
A scene-boundary exit on an unresolved target could emit a finding like
GSAP exit on "__unresolved__" ... with a meaningless tl.set("__unresolved__", ...)
fix hint. An unresolved target is an unknown element: you cannot assert a
missing hard kill on it, so skip the window early in the loop, mirroring the
overlap rule. Exits on resolved selectors are still flagged.
* fix(skills): storyboard review — bg-on-clip rule, slideshow output, parser parity guard
Addresses the storyboard-angle review (jrusso1020):
- M1 (invisible text): frame-worker.md (x3) + SKILL.md Step 5 (x3) now require a
frame's full-bleed background on a class=clip layer, never the #root /
data-composition-id element (the root is clip-gated to its scene window, so a
background on it is not a dependable ground and dark text can land on the black
host body). The assembler already paints frame.md's canvas onto index #root as
the base ground; the per-frame clip rides on top.
- B3 (slideshow truncates to slide 1): slideshow/SKILL.md gains an Output section
(decks render via 'present'; 'render index.html' captures only the first
composition; linear main-line MP4 export is deferred).
- Parser drift: vendoredParity.test.ts guards the three vendored storyboard.mjs
copies (byte-identical + parse-parity with @hyperframes/core).
- skills-manifest.json regenerated for the edited SKILL.md files.

* fix(cli): storyboard review — lint, validate help, snapshot, inspect, capture, render
Addresses the CLI findings from the storyboard-angle review (jrusso1020):
- lint (@hyperframes/lint): accept vendor-prefixed system-font keywords
-apple-system / BlinkMacSystemFont so a system stack with a generic fallback no
longer trips font_family_without_font_face (+ test).
- help: list 'validate' under Project in 'hyperframes --help' (was runnable but
undocumented).
- snapshot: honor -o/--output (the flag did not exist; output was hardcoded to
snapshots/). The dir is resolved once and threaded through capture + contact
sheet + Gemini.
- snapshot: split font status into loaded / error / unused with a one-line
summary; only a real 'error' is reported as FAILED (an unrequested @font-face
is 'unused', not a contradiction with 'loaded').
- inspect: suppress text_occluded across a scene-to-scene crossfade (occluder in
a different data-composition-id mount while a scene is mid-fade); a same-scene
or two-settled-scenes overlap still flags.
- inspect: suppress content_overlap between in-flow siblings governed by the same
flex/grid container (tight stacks / number lockups are layout slop).
- capture: record source resolution (videoWidth/Height) in video-manifest.json
alongside the DOM display box; consumers size off the source dims.
- render: warn when the target carries a slideshow island (render captures only
the first scene, so the MP4 is truncated to slide 1; use 'present').

`crossorigin` on <video>/<audio> forces a CORS-checked fetch. The
server-side renderer downloads media directly (no CORS) so renders
always work, but Studio preview runs in the browser — a media host that
omits Access-Control-Allow-Origin silently fails the load, so the media
shows blank/black in preview while the render looks fine, hiding the bug.
Plain displayed media never needs crossorigin; it's only required to read
pixels/samples back (canvas/WebGL texture, WebAudio createMediaElementSource)
and only when the host is known CORS-enabled. New rule
media_crossorigin_breaks_preview flags it as an error with that guidance.

* fix(producer,lint): id-less media renders blank wash instead of footage
A timed <video>/<audio> identified only by a Studio-stamped `data-hf-id`
(no real `id`) rendered as a flat white/grey wash with dropped audio, and
lint stayed silent so it surfaced only at render.
Root cause, two layers:
- lint `readAttr(tag, "id")` used a `\b` boundary, which treats the hyphen
in `data-hf-id="…"` as a word break — so reading "id" matched the trailing
`id="…"` inside `data-hf-id` and returned a phantom id. `media_missing_id`
therefore never fired for media carrying only a data-hf-id. Switched to a
`(?<![\w-])` lookbehind so a short name can't match the tail of a longer
hyphenated attribute (also fixes "width" matching `data-width`, etc.).
- the render pipeline identifies media by the real `el.id`: frame extraction
keys injected stills as `__render_frame_<id>__`, the runtime frame-swap
matches on `el.id`, and the audio mixer selects `audio[id][src]`. An empty
`el.id` meant injected frames/audio never matched. compileForRender now
assigns a stable positional id to every id-less timed media element before
any stage parses or serves the HTML.
Adds a producer regression fixture (video with data-hf-id, no id) and a lint
test covering the data-hf-id/id collision. Baseline mp4 generated separately.
* test(producer): baseline for video-hfid-no-id regression fixture
Golden compiled.html + output.mp4 (generated on linux/amd64 in the
Dockerfile.test image). Compare-mode passes: compilation, visual (0 failed
frames), and audio (correlation 1.000). A regression to the blank-wash
behaviour fails the visual check.
* refactor: make @hyperframes/lint depend only on parsers, not core
Relocates the leaf utilities lint pulled from core — URL/asset-path helpers,
font aliases, and the slideshow manifest parser — into the standalone
@hyperframes/parsers base, and drops @hyperframes/core from lint's
dependencies. Core keeps back-compat re-export stubs at the old paths, so
producer/studio/cli are unchanged.
Why: lint was the lightweight validator from #1749, but depending on core
transitively pulled studio-server (hono) and bpm-detective — irrelevant to
linting. Now installing @hyperframes/lint pulls only parsers + postcss, and
the core<->lint dependency cycle is gone.
- parsers main entry stays browser-safe (pure utils only); the node:path
asset helpers live behind the new @hyperframes/parsers/asset-paths subpath
- slideshow parser exposed via @hyperframes/parsers/slideshow
* feat(lint): add browser entry; harden CSS url() regex (ReDoS)
@hyperframes/lint/browser — a fully client-side rule engine (lintHyperframeHtml,
lintMediaUrls, shouldBlockRender) with zero node: builtins, so browser-only
editors can validate compositions with no Node.js and no server round-trip.
Closes the browser-validation ask on #1749.
- shouldBlockRender extracted from the fs-bound project.ts into its own pure
module so the browser entry stays node-free
- pure composition primitives (data types, font aliases, URL helper) exposed via
a new recast-free @hyperframes/parsers/composition subpath, so the browser
bundle tree-shakes out the GSAP/recast machinery (verified: esbuild
platform=browser bundles with 0 node builtins)
- lint built with a platform:browser tsup pass — compile-time guarantee the
browser entry never pulls a node builtin
- harden CSS_URL_RE against polynomial ReDoS (CodeQL js/polynomial-redos);
behavior-preserving, verified against existing tests + an old/new parity check
- parsers/lint marked sideEffects:false
* refactor: extract @hyperframes/lint package from core
Moves all lint rules, hyperframeLinter, lintProject, and related types
from packages/core/src/lint/ into a new standalone packages/lint package.
Core keeps a thin re-export stub at @hyperframes/core/lint for backward
compatibility. Consumer imports (cli lint command, producer hyperframeLint)
are updated to import from @hyperframes/lint directly.
Depends on @hyperframes/parsers (PR #1755).
* fix: restore postcss-selector-parser in core (sourceMutation.ts still uses it)
* fix(ci): add parsers+lint to Dockerfile and build before preview tests
* chore: update bun.lock after restoring postcss-selector-parser dep
* test(cli): update lintProject test for string-dir signature from @hyperframes/lint
* refactor(core): single-source the lint engine in @hyperframes/lint
Delete core's byte-identical copy of the lint rule engine and re-point
staticGuard at @hyperframes/lint, so the render-time render-gate and the
studio preview share one rule engine instead of two copies that could
silently diverge. Back-compat preserved via the @hyperframes/core/lint stub.
Addresses review feedback on the dual-copy footgun.
