Add entry bridges (each naming a specific Level 1-3 artifact the
capability slots into) and literal exit bridges across the 7 Level 4
Substance pages, per the novice-to-advanced restructure plan.

Level 2 (anatomy, specification-dial, vocabulary, visual-specs, examples)
gets entry/exit bridges tying it into the Level 1 -> Level 3 arc, plus a
short note on the composition-structure mandate (0aaac7aa3 / PR #2599)
showing the framework enforces its own version of the prompt skeleton.
All existing prompts, renders, and tables are untouched.

The Claude Design Send-to guide rendered at its URL but was an orphan — absent from the
docs nav and llms.txt, so it never surfaced as a fetchable search RESULT (only as body
text in another page's excerpt, which Claude Design's web_fetch rejects). Add it to the
Guides nav (→ llms.txt index) next to claude-design, and give it frontmatter title +
description for a clean entry. This makes the full guide discoverable + fetchable via
search, the reliable path since a URL named only in a tool description is not fetchable.
* docs(guides): resolve the fidelity contradiction (preserve substance, adapt form)
The guide called the rebuild 'lossy by nature' while the checklist demanded 'content
match the brief exactly', with no rule for what to preserve vs adapt. On a live import
CD kept fonts/palette/hero but genericized the source's real figures (2.4M signals/sec,
+240% spike) into vague phrases. Resolve around one principle: substance (real copy,
exact palette/fonts, distinctive figures/data, product names, signature visuals) is
preserved verbatim; only the form (static page to timed multi-scene motion) adapts.
* test(guides): pin the Send-to fidelity contract against silent regression
Address review on #2620: the resolved 'preserve substance, adapt form' instruction is
load-bearing LLM-facing prompt text, but validate-docs only proves syntax. Add a semantic
pin (mirroring packages/cli figma skillContent.test.ts) asserting the three positive
concepts are present and the two retired contradictory phrases ('lossy by nature',
'content match the brief exactly') cannot silently return.
* style(guides): oxfmt the Send-to fidelity-contract test
Wrap the readFileSync call to oxfmt form (printWidth 100); unblocks required Format + its
preflight/preview-regression cascade on #2620.
* docs(guides): redirect Send-to imports to the Send-to guide
Claude Design's only doc-discovery tool is web search, which ranks this Template-First
(Download-ZIP) guide first; the Send-to guide is not indexed, so Send-to imports get
authored against the wrong flow. A body link here lets CD's fetch of this page unlock a
fetch of the correct guide (its URL now appears in a prior fetch result).
* docs(guides): add Send-to redirect note to the Claude Design landing page
The /guides/claude-design landing page (claude-design.mdx) is the indexed nav page and
points only at the Download-ZIP instruction file; a Send-to author landing here got no
pointer to the Send-to guide. Mirror the redirect from claude-design-hyperframes.md.
* docs(media): document automatic proxying for hostile codecs
Describes the shipped behavior: which input codecs render, that live preview
auto-proxies what the browser cannot decode, where the cache lives, and how to
turn it off. Carries the skills notes and the hardening design documents.
* docs(media): align proxy guidance with runtime
## What
Part 2 of the GSAP seek-safety rules (stacks on #2611): the two rules that touch existing catalog content and required reconciliation with an existing rule.
- `gsap_relative_value_second_writer` (error) — a relative var value (`y: "-=15"`) on a property whose target has another writer **active at the relative tween's start**. The relative base is captured at tween init, which reads a different partial state per seek path: sequential seek inits it mid-entrance, a cold render worker inits it at the entrance's end state, and the element teleports at chunk boundaries (production case: all scene nodes jumping ~20px mid-scene). Writers that complete strictly before the start are safe (children render in start-time order within a seek pass — verified against gsap 3.15.0) and are not flagged; neither are single-writer relatives, `from()`/`fromTo()`, build-time `gsap.set`, or relative position parameters (`"+=0.5"`). Selector resolution bails on combinators and cross-composition scoping rather than guessing. Findings aggregate per tween pair and report the overlap window.
- `gsap_timeline_set_initial_hide` (warning) — initial-state hiding via `tl.set(target, vars, 0)` on a paused timeline is not rendered while the playhead sits at exactly 0, so frame 0 shows the unhidden state (verified against gsap 3.15.0: opacity stays 1 after `tl.time(0)`, applies only past 0). Exempt when the target is already hidden by authored CSS/inline styles or a standalone `gsap.set()`, and only sets preceding every tween in source order qualify (mutated position variables resolve to their initial binding in the parser — outro hard-kills don't masquerade as position-0 sets).
- Reconciliation: `gsap_fullscreen_overlay_starts_visible`'s fixHint previously recommended exactly the flagged `tl.set(sel, {opacity:0}, 0)` pattern; it now recommends authored CSS hiding or immediate `gsap.set()`.
- Docs for the full rule family in `docs/packages/lint.mdx`.
## Corpus impact (the reason this is its own PR)
These two rules are the ones that fire on repo-shipped content:
- `gsap_relative_value_second_writer`: 4 errors in `gooey-metaball`, all genuine overlaps. Measured with gsap 3.15.0: ballD diverges **3.31 xPercent / 1.99 yPercent (~8px/5px at 240px ball size)** between sequential and cold seek — a permanent base offset that appears as a teleport at a chunk boundary. Real but modest; happy to fix the block in a follow-up (start the drift at the entrance's end, or use absolute `fromTo`).
- `gsap_timeline_set_initial_hide`: 10 warnings across the catalog after the CSS-hidden exemption (down from 54 pre-narrowing); spot-checked as genuine frame-0 pops with no authored hide (e.g. `vfx-text-cursor` `#phrase-b`).
Adversarially reviewed the same way as #2611 (393-composition corpus + gsap semantics experiments); FP classes fixed and locked as negative tests: precede-only second writers, descendant/cross-composition selector mis-joins, CSS-hidden re-assertions, mutated position variables.
## Tests
Full `packages/lint` suite green at 440 tests including multi-composition roots; `tsc`, oxlint, fallow audit clean.
* feat(studio-server): serve H.264 proxies from the preview route
Wires the codec manifest and the transcoder into the preview surface: the route
negotiates a proxy via a query param and serves it through the existing range
and ETag machinery, composition HTML carries a codec map for the runtime, and
hostile assets pre-warm so a first play does not wait on a cold transcode.
Exposes the three subpath exports the CLI surfaces consume upstack.
Drops the TEMP fallow entry added with the transcoder: it has real importers now.
* fix(studio-server): publish media proxy exports
* fix(parsers): scan HTML comments linearly
* feat(cli): let projects opt out of automatic proxying
Adds media.autoProxy to hyperframes.json plus --proxy/--no-proxy flags, and
forwards the resolved value into the studio and preview servers and the vite
adapter. Lands before the runtime slice that turns auto-proxying on, so the
switch exists before there is any behavior to switch off.
* fix(cli): align media config schema

Windows users with the OS temp dir on a small system drive have hit
C: exhaustion mid-render (Slack ts=1784219488 · CLI v0.7.58 · win32
15 GB / 8-core, ~5500 frames). The engine already honors
HYPERFRAMES_EXTRACT_CACHE_DIR for relocation, but the knob was
undocumented and invisible in diagnostics — the reporter had to piece
together a 4-flag compound workaround including EXTRACT_CACHE_DIR=off.
Changes:
- Extract the env-var resolver into a public engine API
(resolveExtractCacheDir, defaultExtractCacheDir,
EXTRACT_CACHE_DIR_DISABLED_ALIASES) with a typed resolution shape
distinguishing "disabled by user" vs "default" vs "env override".
- Add a Frames-cache check to `hyperframes doctor` that reports the
effective directory, its free space, source (env or default), and
fails with a relocation hint when <2 GB free at that mount.
- Add `hyperframes render --frames-cache-dir <path>` as discoverable
CLI sugar for the env var, including the opt-out aliases
(off/none/false/0) and CWD-safe absolute-path resolution.
- Document the flag in docs/packages/cli.mdx with the field-signal
citation, and add a render example row for the Windows workflow.
- Cover both surfaces with unit tests (6 doctor cases + 4 engine
cases including all disabled-alias variants).

* docs(skills): make the core set the default install on every surface
A field test showed an agent with a real 'make videos' intent installing
all 19 skills: at install time, every surface it could read pointed at the
full set, while the core-eager / workflow-on-demand design only exists
inside hyperframes/SKILL.md - unreadable until after the install decision.
Two traps made full-install the documented default:
- The README Quick Start used 'skills add --yes': skills.sh force-detects
agent environments into non-interactive mode, and a non-interactive run
without --skill installs all 19. Dropping --yes fixes the human path
(the picker opens with nothing pre-selected), but not the agent path.
- marketplace.json listed the full 'hyperframes' bundle first, under the
name an agent installing 'hyperframes' matches; core-skills sat second.
Changes, each behavior verified by an isolated run:
- README Quick Start drops --yes (humans get the picker; verified via a
pty capture that nothing is pre-selected) and points agents and
non-interactive runs at 'npx hyperframes skills update', which from a
clean HOME installs exactly the 8 core skills, refreshes stale ones and
prunes unpublished ones on an existing machine, and is idempotent.
- CLAUDE.md and the docs install guide lead with the same one-liner;
--all is reworded to explicit-request-only at every surface.
- marketplace.json puts core-skills first and both descriptions steer the
default choice; the full entry keeps auto-discovery (no allowlist),
per the skillsManifest core-pin test (56/56 pass).
* docs(skills): close the same install trap in AGENTS.md
Review follow-up on the core-default change: AGENTS.md still carried a
bare 'npx skills add heygen-com/hyperframes' - no --full-depth, and the
same non-interactive-installs-everything trap the README fix closed.
AGENTS.md is the first file Codex/Cursor-family agents read for repo
intent, so it leaked the full-set default to exactly the readers the
core-default policy targets. It now leads with the same core-set
one-liner and policy line as CLAUDE.md.
* docs(guides): add Claude Design → Send to HyperFrames single-file import guide
Self-contained authoring guide for the 'Send to HyperFrames' MCP import path
(distinct from the download-ZIP flow): single self-contained HTML wire format,
the composition contract the importer validates, inline-brand-assets fidelity
rules (base64 data: URIs), no bundled/splash artifacts, keep-the-original-as-
reference, a complete worked skeleton, the animation-pattern catalog, and
determinism rules. Reviewed for technical accuracy against a known-good
imported+rendered composition.

* docs(send-to guide): assets must be resolvable (inline OR fetchable URL), not inline-only
Large media can exceed the import size cap, so "inline everything" is wrong for it,
and the import tool description now states "resolvable refs." Align the guide: inline
data: URIs preferred (fonts/images/logos — the only fully self-contained form), a
publicly-fetchable absolute URL allowed for large media, and explicitly forbid relative
paths / local-file variables / expiring-or-private hosts (the media-expiry trap).

Adds a `--timeout <ms>` CLI flag (and `HYPERFRAMES_TRANSCRIBE_TIMEOUT_MS`
env var) plus a model-slowdown factor in the auto-scaled default so
`hyperframes transcribe` doesn't hard-fail with `spawnSync ETIMEDOUT`
on slow CPUs running heavier whisper models.
Field-signal ts=1784165471 (win32/arm64 emulating x64 on Snapdragon,
CLI 0.7.59) reported the failure on a 63s wav with `-m medium` at ~13x
realtime — the historical 10x-realtime scale (PR #2463) gave 10.5 min
while the machine needed ~13.7 min. Splitting audio and merging offsets
was the manual workaround.
- Add `--timeout <ms>` and `HYPERFRAMES_TRANSCRIBE_TIMEOUT_MS` (min 5000).
Explicit override bypasses auto-scaling; still capped at 12h.
- Add per-model slowdown factor (tiny 0.5, base 0.7, small 1, medium 2,
large 4, large-v3-turbo 2). Multiplied into the 10s/audio-second
baseline so medium/large get proportional headroom while `small.en`
(the default) preserves the historical safety window.
- Wrap whisper's spawn error with a discoverability hint naming
`--timeout`, the env var, and the effective timeout when the child
was killed by SIGTERM/ETIMEDOUT (mirrors PR #2504 protocol-timeout).
- Docs: new `--timeout` row in `docs/packages/cli.mdx` Flags table.
Regression coverage in `packages/cli/src/whisper/transcribe.test.ts`
(56 tests) and `packages/cli/src/commands/transcribe.test.ts` (5 tests):
- Model factor per known name + case-insensitive + safe unknown fallback.
- 63s field-signal case on medium.en → 1_260_000ms (was 630_000ms).
- Explicit override honored below the auto floor + capped at 12h.
- Model factor ignored when overrideMs is set.
- SIGTERM/ETIMEDOUT detection + augmented message contract.
- CLI rejects below-minimum `--timeout` with error naming both the flag
and the 5000ms floor.

Field signal ts=1784047847 (darwin/arm64, 8GB M1, 9 videos + 22 images):
reporter hit Runtime.callFunctionOn timeout and switched to FFmpeg
because the error didn't surface HyperFrames' existing knobs
(PRODUCER_PUPPETEER_PROTOCOL_TIMEOUT_MS env, --protocol-timeout CLI).
Wraps main-render Puppeteer errors matching /Runtime\.callFunctionOn
timed out|Target closed|protocolTimeout/i with an augmented message that
names the effective timeout, the env var, the CLI flag, and the
field-signal shape. Non-matching errors pass through unchanged
(returned as the same instance). Original error preserved via err.cause.
Also adds a dedicated --protocol-timeout row to the CLI docs Flags table
so PRODUCER_PUPPETEER_PROTOCOL_TIMEOUT_MS is discoverable via search.
