Method write_recorded

atomic-repository/src/repository/insert.rs:2124–2307

Write a recorded change to the repository. This method inserts a change that was just recorded, updating both the graph and the tree tables. It's the integration point between recording and inserting. Unlike `insert_change`, this method: - Takes the change directly (doesn't load from store) - Updates tree tables for FileAdd hunks - Assigns new inodes to added files # Arguments `outcome` - The
