Rows stopped sharing one pixel height when lanes gained expansion, so the only
production caller was passing cumulative row coordinates with trackHeight 1 and
both scrollTops zeroed. The parameter names described units the values no longer
carried. The vertical axis is now a row index and the caller keeps ownership of
folding scroll and per-row heights into it.
The local extractIdFromSelector duplicated the `#id`-only regex that
idFromSelector replaced, so both DOM-less paths in
resolveSelectorElementIds (no-iframe fallback and querySelectorAll-throw
recovery) read no id at all for the bracketed `[id="..."]` form writers
emit for CSS-unsafe ids. Deleted the duplicate and imported the shared
reader; both forms now resolve.
Dragging the playhead to the start of the composition needed a very slow
drag. The scrub surface begins GUTTER + TRACKS_LEFT_PAD px right of the
viewport edge, and both scrub paths bailed out when the pointer sat left of
that origin rather than clamping. So the last 80px of the drag toward zero
silently did nothing: the playhead stuck at whatever the last in-range sample
reported, and only a drag slow enough to sample inside the thin sliver before
the origin ever reached 0.
Both paths now share getTimelineScrubTime, which clamps to [0, duration]. One
owner, so the live-feedback path and the committed-seek path cannot disagree
about the edge again.
The R1/R3 residuals on this PR were fixed at the top of the stack, so they
only cleared once every branch above landed. They belong here, next to the
code they correct:
- `idFromSelector` inverts `idSelector` for both regex readers, so the
post-commit cache refresh stops skipping the CSS-unsafe ids `idSelector`
exists to support.
- `deduplicateKeyframes` drops `ease` when it is ambiguous; the flag was the
only honest answer and the last-writer-wins curve belonged to an arbitrary
colliding tween.
- `isStaticPositionHold` is now the single owner of the hold skip. The
`sourceAnimations` filter and the `allKeyframes` filter had diverged on
whether `immediateRender` counts as a property.
- The keyframe-cache setters no-op when the write changes nothing, instead of
handing every subscriber a fresh Map.
- `reset()` clears `focusedEaseSegment`.
- The test hook `delete`s its window key rather than setting it to undefined,
so feature detection still works.
- The `toClipKeyframes` fixture uses `as unknown as T` with the justification
CONTRIBUTING.md asks for.
CLI and Studio feedback were emitted as `survey sent` with `$survey_*`
properties, so every rating was ingested as a PostHog survey response even
though no survey definition, targeting, or popover backs them.
Emit `cli_render_feedback` and `studio_feedback` with plain `rating` /
`comment` properties instead. Same fields, same call sites, same opt-out.

## What
- publishes Plan v2 content-addressed artifacts directly from the Cloud Run planner's private staging directory to GCS
- commits the Plan v2 manifest only after every referenced artifact is durable
- removes the second local Plan v2 CAS directory and preserves the existing Cloud Workflows wire contract
- exports a reusable GCS publisher adapter
## Why
Cloud Run planner, chunk, and assembler requests are independent containers and do not share a filesystem. The distributed contract must contain only durable GCS locators.
This layer makes the Plan v2 publication path object-store-native. Like the AWS parent PR, it still relies on one planner-local frozen v1 tree inside the producer; eliminating that remaining staging tree requires direct Plan v2 emission in a later layer.
## Design invariants
- local paths never cross a request or worker boundary
- manifest and artifact locators derive from one validated GCS output prefix
- immutable objects use generation-zero conditional creation and exact digest/size verification
- retries may reuse exact objects but never overwrite conflicts
- the manifest is the final publication commit point
- chunk and assembler requests independently download and verify only their target artifacts
## Test plan
- [x] all 95 GCP Cloud Run package tests pass
- [x] package typecheck passes
- [x] package build passes
- [x] changed-file lint, format, fallow, and repository commit gates pass
- [x] end-to-end adapter test covers plan, target-scoped chunk, and assemble through Fake GCS with no shared local directory
