The full pure-C facade used by the app: node/project/timeline/viewer/
undo/task/events/serializer/playback/preview/renderer/gizmo/color/
audio/footage/proxy/encoding/exporter/config/disk/ipc/plugin/worker
families, plus undo-group semantics, display renderer handles,
NodeFactory accessors, and per-family pure-C engine tests.
- new primitives: clip_toggle_enabled (per-block flip), clip_set_linked,
sequence_add_default_transition (config-driven, sequence timebase),
node_set_label_many, node_set_color_label, plus observation getters
- toggle-links, default transitions, enable toggles, color labels, and
block renaming now go through the facade; the stray empty undo entry
from block renaming is gone along the way
- nest/multicam/waveform-sync stay as documented composites: they mix
redo_now intermediate state, graph surgery, and app-side computation
that a single primitive cannot express faithfully
- the timeline panel's command execution paths are now fully migrated
- new primitives: ripple_delete_in_to_out (ripple or gap fill plus
work-area state, one undo command), trim_clips_to (batch edge trim
returning a count), delete_empty_tracks (type-filtered batch), and
marker_remove_many (sparse marker deletion by timestamp array)
- delete-in-to-out, edit-to, delete-all-empty-tracks, and sequence
viewer marker deletion now go through the facade; empty operations
no longer push empty undo entries
- footage viewer marker deletion keeps its app path deliberately
(facade marker handles are Sequences, not generic viewers); the
tentative subtitle track and pointer drag chain stay as documented
leftovers
- new batch primitives: split_clips (link-preserving, single undo
command), delete_clips (gap replace + optional ripple with explicit
region support), ripple_delete_range, marker_add_ex with color
- razor/split-at-playhead, clip delete, ripple-to-point, track delete,
and the non-dialog marker path now issue facade commands instead of
the app's own undo command classes
- batch operations deliberately produce one undo command per user
action (deleting twenty clips is one entry, not twenty); selection
and transition removal stay UI-side as documented leftovers
- new facade API: video params ex (dimensions/rate/par/interlacing/
preview format/divider), audio params, preview divider, and
undoable-flagged setters mirroring the dialog's dual undo/no-undo
modes; label setting gains node_set_label_ex
- the dialog's own SequenceParamCommand is gone; accept now issues
facade calls (per-field commands, unchanged fields skipped)
- preset system stays UI-side by design: its flat XML schema never
touches engine objects
- the auto-cache checkbox maps to the engine's existing stub (no undo
noise)
- undoable track removal (content restored on undo) and true-move
track reordering assembled from the edge commands (the engine has
no move-track API)
- track height/mute/lock getters and setters, documented as
non-undoable to match the engine's current semantics
- undoable marker add/remove/rename; duplicate timestamps are
rejected with E_STATE instead of hitting the engine's debug assert
All four are undoable and reuse the timeline/ command classes verbatim
(BlockSplitCommand, TrackRippleRemoveAreaCommand, BlockTrimCommand,
ReplaceBlockWithGap+PlaceBlock), with undo/redo assertions covering
split halves, media-in alignment on trim, ripple shift amounts, and
full restoration on undo
- oakengine_sequence_add_track and add_footage_clip are the facade's
first editing primitives: undoable track creation and clip placement
with full range validation, clip enumeration, and gap filtering
- oak-cli transcode closes the loop: media file -> import -> clip ->
render, producing scaled PPM frames and a WAV from just the C ABI
- engine fix uncovered by transcode: the render worker used an invalid
empty AudioParams for IPC render frames, crashing any sequence that
contains audio; it now derives them from the rendered node itself
- sequence_new hardens its defaults against missing audio config keys
