Crate ashlar_store 

Documents: Arc snapshots, revisions, undo history, versioned formats with migrations, autosave.

• Store: the document as an Arc<D>, edited copy-on-write, with a Revision per state, undo/redo, merged gestures, compound edits (Transaction) and dirty tracking.
• History: the undo stacks on their own (labels, extra state, merge keys, step and byte limits, optional branches).
• Tracked and Memo: per-part revisions and small revision-keyed caches for views.
• SnapshotCell: the latest snapshot for real-time and worker threads, lock-free.
• Format: the file envelope, migrations, refusal of newer and foreign files, durable saves.
• Autosave: an autosave ring with crash detection and RecoveryCandidates.

Headless and wasm32-clean (the background autosave writer is native only).
