Preserve surviving style references and terminal typing style while replacing scalar-aligned UTF-16 ranges. Reject affected fields and preserved run data before publication; reuse existing offline text intents after rebasing onto remote styles.

Validate exhaustive ranges, history preservation, interrupted commits and lost replies. Retain six independent native fixtures and extend the twelve-client native/Rust workload to insertion, formatting and cross-run replacement.

Checks: 180 Rust tests, eight doctests, 126 Python tests, Clippy and formatting; 7,987 ASan executions; 1,280 mixed editing intents through an outage with independent cold OneNote verification.
