Extend the durable workload through split, dependent right-text editing and join. Model complete character partitions and paragraph graphs, retired identities, original uncertain receipts and every reader timing interval. Verify real cache trace output independently and retain compatibility with older captures.

The 12-client outage run passes 1,536 document publications, 256 Rust appends, 256 native edits and 29,922 reader snapshots. Fresh OneNote reopening matches 261 paragraphs and preserves 655 active identities. Receipt ledgers, server-visible lock overlap and owned VM teardown pass. Add native split/join overlap regressions; 136 Python tests, affected Rust tests and Clippy pass.
