Extends the studio-preview fix to the render path and the asset-discovery
utilities, which share the same resolver and had the same defect.
`rewriteAssetPath` takes an optional `assetExists` probe. A plain relative ref
authored in a sub-composition (`_shared.css`, `clip.mp4`) is re-pointed at the
composition's own directory when that sibling exists on disk; project-root refs
with no sibling (the registry's `assets/logo.png` convention) stay as authored.
Callers that can see the filesystem supply the probe, so the module stays free
of node:fs.
Also fixes a second defect in the inliner: `<head>` <link> hrefs and external
script srcs are hoisted into the root document but never went through the
rewrite at all, so even the documented `../` form escaped the project and 404'd
at render time.
Wired into the preview bundler, the producer compiler, the studio preview
builder, the HEVC preview lint, the project lint's asset scans, publish proxy
baking, and media-treatment source resolution.
Chrome 112+ / Firefox 117+ / Safari 16.5+ support native CSS Nesting.
A nested rule like '.title { … }' inside '[data-composition-id="intro"]
{ … }' resolves at match time to '<parent> .title' via the implicit
'&' prefix.
'scopeCssToComposition' walks every rule via 'root.walkRules' and re-
scopes selectors, but it did so for nested rules too — producing
'[…scope…] .title' inside '[…scope…] { … }', which nesting then
prepends AGAIN to '[…scope…] […scope…] .title'. Since the composition
root only appears once in the DOM, the doubly-scoped selector never
matches — the nested rule appears 'just ignored' as the reporter
described (#2721).
Reproduced on 0.7.66 with the reporter's exact composition. Fix: add
'isNestedInsideAnotherRule' predicate — mirrors the existing
'isInsideGlobalAtRule' — and skip nested rules in the walkRules
callback. Top-level rules still get scoped; their nested descendants
inherit scope naturally via CSS Nesting at match time.
Added two focused tests:
- 'preserves nested-rule selectors so CSS Nesting inheritance works
(#2721)' — asserts nested '.title' and 'h2' selectors stay verbatim
while top-level rules keep scoping.
- 'preserves deeply-nested CSS Nesting rules (#2721)' — same rule at
depth 3.
All 37 existing scopeCssToComposition tests still pass.
Fixes#2721.

## Problem
For a `fit_to_scene` B-roll where the composition's intrinsic timeline (e.g. `data-duration=1.0s` → 30 frames) is shorter than the scene it fills (e.g. 4.8s narration), the producer renders only the intrinsic 30 frames and the downstream compositor frame-holds/PTS-stretches that fixed clip to the scene length. Spreading 30 unique frames over 4.8s starves motion to ~6 effective fps → a visibly choppy result. Root cause: the producer welds one `composition.duration` to both the frame count and the 1:1 seek mapping, with no notion of a target output length.
## Fix
Add optional `renderStretch: number` (default `1.0` = no-op), `renderStretch = intrinsic / target`:
- **Frame count** comes from the target: `outputDuration = intrinsic / renderStretch`, `totalFrames = outputDuration × fps` (`probeStage.ts`). `composition.duration` stays intrinsic (drives video/audio windows).
- **Per-frame seek** is scaled: `time = (frameIndex / fps) × renderStretch`, so the N output frames map across `[0, intrinsic]` — a fresh frame per output frame.
All seek sites go through a single shared `outputFrameToTimelineSeconds(frameIndex, fps, renderStretch)` helper (`core.types.ts`), consumed by every capture path so none can silently diverge:
- parallel (`parallelCoordinator.ts`), `sdr_streaming` (`captureStreamingStage.ts` ×3), `sdr_disk` (`captureStage.ts`), HDR loops.
- DrawElement + static self-verify (`frameCapture.ts`) — ground-truth seek uses the same mapping, so PSNR compares like-for-like (no spurious verification failure on stretched comps).
- Distributed path: `renderStretch` threaded through `DistributedRenderConfig` → chunk workers, and **folded into the plan hash only when `!= 1`** so a pre-stretch cached plan is never reused.
With `renderStretch = 1` (or omitted → `?? 1`): every seek is `×1.0` (IEEE-754 identity), frame counts unchanged, and the plan hash is byte-identical — a provable no-op. `player.ts` absolute-seek is untouched.
## Verify
- typecheck (core + engine + producer): pass. lint/format/fallow/commitlint: pass. `planHash` + `renderRequest` unit suites: pass.
- Adversarial self-review found + fixed three capture-path gaps (streaming, self-verify, distributed) before this revision.
- **Not yet runtime-verified** on a real render — needs a fit_to_scene render at `renderStretch < 1` confirming N distinct frames over the target length (draft until then).
Paired with experiment-framework#42766, which computes and forwards `renderStretch = hf intrinsic / scene duration`.
🤖 Generated with [Claude Code](https://claude.com/claude-code)
`bundleToSingleHtml` compiles `data-duration` into `data-end` (in
`compileTimingAttrs`), then calls `validateHyperframeHtmlContract` against
the compiled HTML. The linter's `deprecated_data_end` rule fired on the
compiler's own consistent output — `<audio data-start="0" data-duration="18"
data-end="18">` — because `diagnoseDerivedEnd` unconditionally emitted a
`deprecated-end` diagnostic whenever both attributes were present, ignoring
whether the derived value matched.
Reporters routed this as "raw-source lint passes with 0 errors and 0
warnings, but `check --strict` still logs StaticGuard noise about
data-end without data-duration." Field cluster: cli-feedback crons 61-68,
n=25+ across darwin/arm64, darwin/x64, linux/x64, win32/x64, and versions
0.7.56 through 0.7.64. L3 reporter cite (ts=1784519869): "bundleToSingleHtml
compiles data-duration into data-end, then validates the compiled HTML and
reports its own generated data-end as deprecated."
Fix: `diagnoseDerivedEnd` now stays silent when the paired `data-end`
matches `data-start + data-duration` (within a 1ns epsilon to absorb
IEEE-754 residuals like `0.1 + 0.2 = 0.30000000000000004`). Truly-legacy
authoring shapes — `data-end` alone with no `data-duration`, or a
`data-end` that disagrees with `data-duration` — still fire
`deprecated_data_end`, with a refined message that names the drift on the
conflicting variant.
Facets covered: (a) validator treats compiler-derived `data-end` as legal
when paired with `data-duration`, and (e) recognizes the compile-time
rewrite site (`bundleToSingleHtml` → `compileHtml` → `compileTimingAttrs`).
Facets (b) stderr gating, (c) terminal JSON verdict, and (d) audio-not-
dropped are unblocked transitively — StaticGuard's `console.warn` is
already gated on `!isValid` and never drops audio; the check command
already emits JSON on every terminal path; so once the false-positive
diagnostic stops firing on compiler output, the noisy stderr line and the
misleading "check appears to fail" reporter framing both go away without
further wiring.
