 # Internal: Command Restore
 
 ## Purpose
-Define the implemented `narratio restore` contract: committed remote-state discovery, deterministic plan classification, safe file install semantics, and restore reporting.
+Define the implemented `narratio session restore` contract: committed remote-state discovery, deterministic plan classification, safe file install semantics, and restore reporting.
 
 ## Inputs and outputs
 Inputs:
-- CLI flags: `--config`, `--session`, `--session-id`, `--previous-session-id`, `--dry-run`, `--force`, `--include-audio`.
+- CLI syntax: `narratio session restore <session_id>`.
+- CLI flags: `--config`, `--campaign`, `--session`, `--previous-session-id`, `--dry-run`, `--force`, `--include-audio`.
 - Resolved/validated `pipeline.yml` and `session.yml`.
 - Configured remote object store.
 - Remote committed current-state markers (`current/run_id.txt`, `current/manifest.json`).
