+- `get outpath`
+- `set outpath <hop1_hex,hop2_hex,...>`
+- `set outpath direct`
+- `set outpath clear`
+- `set outpath flood`
+
+**Parameters:**
+- `hopN_hex`: Hop hash, `2`, `4`, or `6` hex characters. All hops must use the same width.
+
+**Notes:**
+- These commands require remote client context (they target the caller's ACL entry).
+- The path hash size is inferred from the hop hash width.
+- `outpath` overrides the primary direct route used for replies to the caller.
+- `direct` sets a zero-hop direct route for a caller reachable without repeaters.
+- `clear` forgets the current direct path and allows normal path discovery to repopulate it.
+- `flood` forces replies to use flood packets until the client logs in again.
