- Add HostNotification::SelectionChangedV4 { tab_id, handles } with discriminant 7
- Broadcast active-tab selection changes at update() and automation_op boundaries
- Use stable order-independent signature to avoid spurious hover notifications
- Clear Scene selection in automation new/open to avoid stale handles
- Add crates/ocs_plugin_api/ARCHITECTURE.md and module-level rustdoc
- Cross-link README.md and docs/plugin-architecture.md
- Fix test env race with shared ENV_LOCK and EnvVarGuard helpers
#249 — plugin XDATA written via write_record survived only in memory: the
acadrust DWG writer dropped ExtendedData::records on save. Bump acadrust to
e88a9a6 (records now encode to EED and decode back on read) and fix the host
side that fed it:
- ensure_app_id allocates a real APPID handle; a null handle serializes as
0 and the EED reference can't resolve, so the XDATA vanished on reopen.
- write_record / remove_record drop stale raw_dwg_eed for the target app so
an edit made after a save/reopen wins over the pre-edit bytes.
#250 — out-of-process plugins got a throwaway document_mut() snapshot, so
edits to existing entities were silently discarded and deletion wasn't
expressible at all. Add the missing mutation surface:
- UpdateEntity / RemoveEntity IPC requests + HostApi::update_entity /
remove_entity (default in-process impls, RPC overrides on the client that
invalidate the stale document cache).
- Scene::update_entity replaces the entity in place, preserving its handle
and owning block, and reseeds only its derived caches; remove reuses the
cache-coherent erase_entities (which also honours layer locks).
- document_mut() is documented as a local-only snapshot out-of-process.
