Add the typed document facade and plugin IPC adapter. Prepare bulk edits before mutation, preserve undo and dirty state, keep profile elevations, validate numeric inputs and session bindings, and generate Python constructors with typed results. Reuse existing entity transforms and profile conversion. Compute mass properties and closed-surface bounds in cadkernel; pin its main revision 6a5e6fc2822f6af6b2611cd605b44437b35158f0. Keep plugin API metadata at version 6. Validation: 646 native application tests, 597 kernel tests, 12 document API tests, 91 plugin API tests, 3 Python tests, default/IPC feature builds and wasm32 check passed.

//! The transport boundary — the ONLY plugin↔host boundary.

//! Portability contract (SPSC / flume / shared-memory safe): a transport impl
|
|
//! must (a) accept `&self` calls from many threads and serialize sends internally,
|
|
//! (b) demultiplex responses to the right caller by a correlation id, (c)
|
|
//! block-with-timeout, (d) expose liveness. This matches the existing V4 channel
|
|
//! shape, so swapping socket → shm changes only the impl, never the facade.
