WaterrrForever 7d21cc9b8a fix(skills,cli): close four reproduced contract gaps from the CLI feedback digest (#2476)
* fix(cli): invalidate the skills nudge cache after a successful install/update/check

The passive "N skills out of date or missing" nudge reads a 24h config
cache that only the background check (on non-skills commands) ever wrote.
The skills commands themselves are excluded from the nudge pipeline, so a
successful `skills update`/install/check never refreshed or dropped the
cached verdict — the pre-install count kept printing on every other
command for up to 24h.

Reconcile commands now drop the cached verdict (counts + timestamp) so
the next command's background check re-runs for real. The offline
presence-only path deliberately keeps the cache: that run learned nothing
about freshness.

* fix(skills): win32-safe npx spawns in media-use + accurate whisper wording

The Whisper transcribe fallback and the Kokoro local-TTS delegation both
spawned a bare "npx" via execFileSync — on Windows npx is npx.cmd, which
spawn cannot exec, so both paths died with `spawnSync npx ENOENT`. Route
them through the skill's existing resolveSpawnCommand (node + npx-cli.js
on win32, no shell:true), same as the audio engine's TTS spawns.

Also corrects the "bundled with the hyperframes CLI" claim about
whisper.cpp: it is resolved from PATH / installed via Homebrew / built
from source with git+cmake on first use, and models download from
HuggingFace — nothing whisper is shipped in the package.

* feat(skills): canonical fully-silent marker + auth status exit-code docs

product-launch's Step 3.1 gate said "or the project is marked silent"
but nothing defined how to mark one, and audio.mjs unconditionally
retrieved BGM. Define the canonical marker — `music: none` in the
storyboard's top YAML block, plus no SCRIPT.md — and honor it:
audio generate produces nothing (removing stale audio_meta.json, since
absence is what assemble treats as silent), and `music: none` with
narration keeps TTS while turning BGM off.

Also documents the `auth status` exit-code contract (exit 1 while
signed out is the normal offline state, not a failure) in the
product-launch Step 0 note and the CLI skill's cloud reference.

* fix(skills): transient-init retry for standalone animation-map and contrast-report

The standalone helpers called initializeSession exactly once, so a valid
modular project — whose sub-composition timelines register asynchronously
— could hit the readiness deadline and die with the transient
"zero duration / Runtime ready: false" diagnostic the render pipeline
retries (probeStage). Add initializeSessionWithRetry to the shared
package-loader (both byte-identical copies): close the crashed session
and retry once with a fresh browser, gated by the engine's canonical
isTransientBrowserError — now re-exported from @hyperframes/producer,
with a frozen fallback pattern list for older published packages. The
"Runtime ready: true" fast-fail (a genuine authoring bug) still fails
without a retry.

* feat(skills): extend the fully-silent marker to faceless-explainer and pr-to-video

Both workflows reuse product-launch's audio model — their Step 3.1 gates
carried the same undefined "marked silent" phrase, and their (intentionally
identical) audio.mjs copies had the same unconditional BGM retrieve. Port
the `music: none` marker handling into both copies, define the marker in
their SKILL.md Step 3.1 and story-design references, and turn the
copies' "intentionally identical" header claim into a byte-identity pin
test so the next fix can't silently miss one of them.

* test(cli): reset the prune mock explicitly instead of relying on restoreAllMocks

The converge test's toHaveBeenCalledTimes(1) held only because vitest 3's
vi.restoreAllMocks() clears vi.fn() call state; vitest 4 restores spies
only, so the count would accumulate across tests and fail. Reset
pruneOrphanedLockEntries in beforeEach like the other manifest mocks —
passes under both vitest 3.2.4 (pinned) and vitest 4.

* test(skills): close review findings — package-loader pin, whisper win32 parity, quoted-none

Review follow-ups on #2476:

- package-loader.mjs byte-identity pin (the elevated concern): the two
  copies now carry initializeSessionWithRetry + FALLBACK_TRANSIENT_PATTERNS,
  exactly the shared-logic shape a future fix could land in one copy and
  miss in the other — same enforcement as the audio.mjs pin.
- whisper win32 call-site parity: runWhisper's npx resolution lifted into
  lib/npx-sync.mjs (resolveNpxInvocation, injectable params matching the
  localTtsGenerate idiom) with the same three-branch coverage as the
  Kokoro site — plus the hard-fail contract (throws actionably, since the
  whisper fallback has no next provider to fall through to).
- quoted music: "none" pin: the vendored storyboard parser strips matching
  quotes at parse time (stripQuotes), so the silent marker already accepts
  the quoted spelling — pinned so that stays true.

# Requirements & Caches
## Credential & key priority
Run `npx hyperframes auth status` to see what's configured and which engines a workflow will use (see the skill's **Preflight** section). Keys resolve in this order — **first match wins**:
| Provider | Resolution order (first non-empty wins) | Local deps when used |
| ------------------------------------ | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------ |
| **HeyGen** (TTS + BGM/SFX retrieval) | `$HEYGEN_API_KEY``$HYPERFRAMES_API_KEY``~/.heygen/credentials` (shared with heygen-cli; `$HEYGEN_CONFIG_DIR` overrides the dir; written by `hyperframes auth login`) | none (REST) |
| **ElevenLabs** (TTS fallback) | `$ELEVENLABS_API_KEY` | `pip install elevenlabs` |
| **Lyria** (BGM fallback) | `$GEMINI_API_KEY``$GOOGLE_API_KEY` | `pip install google-genai` |
| **Kokoro** (TTS, no key) | always — final voice fallback | `pip install kokoro-onnx soundfile` |
| **MusicGen** (BGM, no key) | always — final music fallback | `pip install transformers torch soundfile numpy` |
`hyperframes auth login` (browser OAuth) is the recommended setup: one sign-in, every project, no per-repo `.env`. An OAuth login is sent as `Authorization: Bearer`; an API key as `X-Api-Key`; both are tagged with `X-HeyGen-Source: cli`. OAuth CLI users can consume the web-plan free allowance for HeyGen TTS (10 min/month); API keys follow the normal API billing path. With no HeyGen credential, voice/BGM run fully locally (Kokoro / MusicGen) — `hyperframes auth status` and `hyperframes doctor` both report whether those local deps are installed.
## Model caches & system dependencies
Each command downloads its own model on first run and caches it under `~/.cache/hyperframes/`:
- **TTS (HeyGen)** — no local deps; needs a HeyGen credential + `ffmpeg` on PATH (to transcode the mp3 response to `.wav`). Credential resolves like the CLI: `$HEYGEN_API_KEY``$HYPERFRAMES_API_KEY``~/.heygen/credentials` (shared with heygen-cli; run `npx hyperframes auth login`). An OAuth login is sent as `Authorization: Bearer`; an API key as `X-Api-Key`; both include `X-HeyGen-Source: cli` so the backend can apply CLI OAuth free usage.
- **TTS (ElevenLabs)** — same as HeyGen: API key + `ffmpeg`.
- **TTS (Kokoro)** — Kokoro-82M (~311 MB) + voices (~27 MB) in `tts/`. Requires Python 3.8+ with `kokoro-onnx` and `soundfile` (`pip install kokoro-onnx soundfile`). Non-English text also needs `espeak-ng` system-wide.
- **BGM (Lyria)** — needs `$GEMINI_API_KEY` or `$GOOGLE_API_KEY` + `pip install google-genai`. No local model cache.
- **BGM (MusicGen)** — `pip install transformers torch soundfile`. `facebook/musicgen-small` (~300 MB) cached under `~/.cache/huggingface/` on first run.
- **Transcribe** — Whisper model size depending on choice (75 MB 3.1 GB) in `whisper/`, downloaded from HuggingFace on first use. `whisper.cpp` itself is NOT bundled: the CLI resolves it from PATH, installs via Homebrew (macOS), or builds it from source with git+cmake on first use (`$HYPERFRAMES_WHISPER_PATH` overrides).
- **Remove-background** — `u2net_human_seg` (~168 MB ONNX) in `background-removal/models/`. Peak inference RAM ~1.5 GB.
Run `npx hyperframes doctor` if a command fails because of a missing dependency.
