Place prepared Takes on an independent Timeline with gaps and overlaps. Present picture, sound and captions through explicit Use rules while preserving source timing and project-authored styles.
Unify Companion bands, parameter ownership and source writeback in Studio. Migrate components, examples and authoring guidance, remove retired Speech/Semantic Track interfaces, and retain protocol identifiers at @1.
Validation: repository suite (786 tests; six sandbox-blocked tests passed on permitted rerun), 43 Studio tests after audit fixes, TypeScript, public declarations, four example-package builds, chat Source check and npm file inventory.
Speech publishes semantic timing and original audio. Media Performance and project components consume the prepared material, preserving source offsets across Takes while controlling their own framing and motion.
Add explicit renderer programs for coordinated HTML/CSS/JavaScript scenes, with typed media children, backdrop filtering and blending. Remove stand-in and estimated-take preview paths, migrate Sources and documentation, and demonstrate a Moment-driven video-to-diagram handoff.
Delete packages/reference-video-tools: the route/revision/variant state
machines, pending_observations, the check gates, layout_accept,
render_element (a Build outside Build), render_previews (posters are
designed, not rendered) and the per-video global cache tree. What an
agent needs outside a Build survives as dumb local commands in video-cli:
hypit media probe/cut/frames/tile/shots/fetch and hypit vocabulary.
Drop the four-word cue rule from @hypit/script; cue breaks are craft,
fit is the caption component's own knowledge. @hypit/yt-dlp writes to
the file the caller names. Prompts and measured parameters are kept
verbatim in .agents/development/observation-knowledge.md for the Skill.

The umbrella video-contracts package collapsed eight unrelated
vocabularies into one release unit. Public video communication now
lives in small, independently versioned contract packages: narrative,
media, program-space, speech, speech-evidence, semantic-map, visual-ir
and composition. Speech implementation packages are renamed for what
they do (speech-spine, speech-basis, speech-alignment), realization
folds into run, and hyperframes-render becomes render-hyperframes with
a renderer-neutral Visual IR spec. Every model package gains a direct
activation entry, and shared video test fixtures move to test-support.
Example package locks are regenerated for the decomposed closure; the
graph-check, live, echo-pro-aroll and bootstrap sources all compile
against the new package set.
Narratage (narration + montage) is the project, framework, npm scope
(@narratage/*) and CLI command. SVML remains the name of its markup
language, so file suffixes (.svml/.svs/.svrun), source Headers and
svml.* wire format ids are intentionally unchanged. Example locks are
regenerated because package manifests participate in artifact digests.
The @0/@2/@4 numbers were rewrite-internal draft counters, not released
format versions. No external consumer or persisted data depends on them,
so the first public format of every id is @1. Negative-format tests use
@9 as the deliberately unknown version. Example package and runtime
locks are regenerated because format ids participate in digests.
