-### Atomic Transactions (Experimental)
-
-[Detailed design and usage docs](internal/atomic/README.md)
-
-Add and delete operations are executed via a lightweight transactional journal to prevent partial state (half-written manifests or orphaned chunks).
-
-Workflow:
-
-1. Start a transaction: new/replacement files written under `.txn/<id>/new/`.
-2. Deletions move originals to `.txn/<id>/trash/`.
-3. Commit promotes all staged files (atomic renames) and removes trash.
-4. Rollback removes staged files and restores trash originals.
-
-Manual recovery:
-
-```
-sietch recover --retention 24h
-```
-
-Scans `.txn/` for incomplete transactions and resumes or rolls them back. Completed journals older than the retention window are purged.
-
-Limitations / Next Steps:
-
-- Current scope covers `add` and `delete` commands.
-- Further commands (sync, sneakernet transfer) can adopt the same API later.
-- Fault injection hooks for deterministic testing are planned.
