* chore: prepare v0.8.46
Draft only, not tagged: bun run release:prepare 0.8.46 --no-tag.
Changelog rewritten in plain words for the one change since v0.8.45
(#4031, adaptive per-frame motion-blur sample count). Cutting the
release is a separate step on Miguel's word.
* docs(release): fix false render-time savings claim in v0.8.46 notes
Adaptive sampling never drops below the old fixed-16 default; it only
adds cost on frames that measure real spatial motion. Per Miga's review
on #4033.
- Lint no longer reports root_dimensions_mismatch for sub-compositions, the
false positive v0.8.43 shipped with; a top-level mismatch is still reported
and a viewport-meta-only mismatch gets its own wording (#4012)
- The streaming encoder accepts lockGopForChunkConcat and gopSize, emitting the
same arguments as the disk encoder. Off by default, so an existing render
produces an unchanged FFmpeg arg list (#3973)

- Portrait compositions render the full frame when the project was
scaffolded at a different size: html/body are sized to the composition
root at runtime; new lint warning root_dimensions_mismatch (#4005,
fixes#4001)
- render_complete telemetry adds composition_element_tags,
aroll_video_count, heygen_video_count; render_error adds error_name and
failed_stage_code (#4004)
- Catalog docs "Source" accordion titles are plain strings, so docs
search no longer shows [object Object] (#4006)

* chore: release v0.8.42
- Studio preview works for projects whose path has non-Latin-1 characters (#3982)
- Studio render downloads use RFC 6266 headers for non-Latin-1 filenames (#3984)
- check --json reports HDR auto-promotion; render prints one warning (#3985)
- Forced --sdr renders tone-map HDR sources before extraction (#3981)
- Render/preview workers no longer survive as orphans after Ctrl-C or parent exit;
cancellation reaches final artifact promotion; HYPERFRAMES_RENDER_DETACHED=1 for
intentionally detached renders (#3974)
- HDR preflight test coverage for held tails (#3963)

* chore: release v0.8.42 notes — name the #3982 symptom and scope
- #3982 entry: a Studio preview server crash for compositions whose file path
has non-Latin-1 characters (the project directory is not involved)

* chore: release v0.8.42 notes — name the #3982 symptom
- #3982 entry: the uncaught ETag TypeError took the preview server down, so
call it a Studio preview server crash rather than a preview failure

* test(sdk): render-faithfulness test for serialize() bake contract (WS-F)
Adds session.render-faithful.test.ts with 8 assertions covering the full
op batch (setStyle + setText + setTiming + addGsapTween + moveElement).
Confirms serialize() emits fully override-baked, render-ready HTML — this
is the SDK-side guarantee that the backend render input needs no separate
override-set field. Also asserts GSAP <script> edits and data-composition-
variables survive serialization unchanged.
Decision recorded: no SDK bake helper. session.serialize() IS the bake.
Content-address → zip → S3 upload → pointer-swap is host/backend (WS-P/WS-R).

* test(sdk): close the two false-positive slots in the bake-contract assertions
`toContain('data-end="5"')` in the setTiming case and `toContain('data-y="50"')`
in the full-batch case both match a DIFFERENT element in the fixture —
hf-title already ends at 5, hf-box already sits at y=50 — so either assertion
would still pass if its write regressed to a no-op. Paired each with the
disappearance of the target element's own pre-mutation value, which is the
pattern the setText case already uses.
* test(sdk): assert the canonical data-duration timing shape, not legacy data-end
The false-positive slot was hiding a real behaviour change. `setTiming` now
routes through the parsers' `writeClipTiming`, which canonicalizes timing onto
`data-start` + `data-duration` and REMOVES the legacy `data-end`. The
full-batch case asserted `data-end="4.5"` and failed once rebased onto main;
the standalone case asserted `data-end="5"` and passed only because hf-title
carries that exact value in the fixture — the very collision this pass set out
to close.
Both now assert the start/duration pair and the disappearance of the target's
own legacy end.
