This file reserves session ID 0015 for vscode-cowriting-plugin. The driver replaces this body with the full transcript and renames the file to its final SESSION-0015.0-TRANSCRIPT-2026-06-10T22-37--.md form at session end.

Launch prompt

Implement Feature #14 (F5 cross-rung format + round-trip) per the graduated spec vscode-cowriting-plugin-content/specs/coauthoring-cross-rung-format.md — plan just-in-time from its §7.2 slices, then execute; done = contract + schema published, unit + host E2E green (round-trip, merge, fail-safe, unknown-field preservation all exercised).

Deferred decisions

Autonomous-mode low-confidence calls the driver made and would have liked operator input on. Appended as the session runs; surfaced at finalize. Empty if none.
