+#### Invalid Session ID

+```bash
+$ agents session show 01INVALIDSESSIONID000000000000
+[red]Session not found:[/red] 01INVALIDSESSIONID000000000000
+```
+
+The CLI raises `SessionNotFoundError` when the ULID does not exist. Double
+check the ID or list sessions again.
+
+#### Database Offline
+
+```bash
+$ agents session list
+[red]Error:[/red] Database unavailable: connection refused
+Hint: run 'agents init'
+```
+
+If the database service is unavailable, restart it or run `agents init` to
+recreate the local database.
+
+#### Import Validation Failure
+
+```bash
+$ agents session import --input ./corrupted-session.json
+[red]Import error:[/red] Checksum mismatch (expected sha256:..., got sha256:...)
+```
+
+Corrupted or tampered exports fail validation. Re-export the session or verify
+the file integrity before retrying.
