- capi: oakengine_node_output_connection_at/_at_ex returned the source
node as the connection destination; the actual destination is
conn.second.node(). Out-edge enumeration was useless, so the node
view could only draw in-edges and randomly lost whichever edges
needed the out-edge path (random per context build order).
Regression test in oakengine_node_test
- project teardown: Project::clear() pre-notifies node removal while
nodes are fully constructed (observers used to crash on
half-destroyed nodes); childEvent suppresses the removal dance while
clearing; Node::disconnect_all/disconnect_edge get a silent mode for
teardown so no invalidation/events touch dying members
(is_being_cleared); ClipBlock marker disconnect guarded against
dead viewer/markers; ProjectCopier and PreviewAutoCacher drop
project references on Project::destroyed instead of disconnecting
dead objects at shutdown
- preview: add oakengine_preview_request_get_audio_sample_count; the
viewer queried sample count by passing nullptr to get_audio_samples
which rejects it, so all playback audio was silently dropped
- app: fix unterminated input-id memcpy in ResolveGroupInput
(nodeparamviewitem, widgetbridge) that corrupted every parameter id
- app: unsubscribe raw C-API event subscriptions in destructors of
NodeParamViewKeyframeControl, NodeParamViewConnectedLabel and
ExportDialog; playhead events used to fire into dead widgets
(crash when dragging the playhead)
- tests: preview request roundtrip (video frame + audio range) and
free-while-active teardown coverage; env-gated OAK_DEBUG_EDGES /
OAK_DEBUG_INVALID_INPUT diagnostics
- docs: investigation notes in docs/zh/
- Track: new InputDisconnectedEvent trims blocks_/block_array_indexes_
when a block edge is removed outside the Track's own operations
(block deletion, undo commands detaching a whole track). Previously
blocks_ kept dangling pointers and Project teardown crashed in
track_length() (ASan heap-use-after-free in oakengine_timeline_edit /
oakengine_sync). The persistent array map is intentionally not
rewritten so undo of remove_track can re-attach the clips; replace_block
guards the handler with ignore_block_disconnect_
- filefunctions: honor OAK_CONFIG_DIR to redirect the configuration
root; QStandardPaths ignores XDG_* on macOS, so the engine tests read
the real user config (a stale 0.1.x file) and failed frame-rate
assertions. All engine tests now set OAK_CONFIG_DIR to their tmpdir
- init test: chdir to the fixture directory before loading
project_with_footage.ove so the engine's moved-project footage
relocation does not rewrite the stored relative filename
- renderworkerpool: do not let the render worker inherit
QT_QPA_PLATFORM=offscreen from a headless host process; the worker
needs a real platform GL context and exited immediately otherwise,

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.
- clip-level loop mode (off/loop/clamp), undoable
- per-channel audio levels as one-frame RMS at a timestamp
- waveform min/max buckets over a footage range, rendered on demand
- two real fixes uncovered by this family: conform completion signals
were starved by msleep-only waits (audio renders always came back
empty), and incomplete tickets from conform-pending renders are now
retried until the conform is ready
