Adds Leader validation and annotation/dimension-style reference checks to ocs_plugin_api, maps 15 writable and 5 read-only fields in the adapter, and adds staged_python_leader_lifecycle_over_real_ipc covering C/R/E/D/U/I/V/P. The W gate stays open: acadrust's DXF writer omits the annotation handle and DXF reads drop annotation_offset; DWG R2010+ does not store text size or the hookline flag. Each gap is pinned by a canary assertion. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
