 - `drop` is measured from consecutive predicted origins (not a hard-coded tick
   interval). At high fall speeds the 2-unit band can be skipped between
   commands; a higher frame rate improves reliability. Best-effort by design.
+- **Assist timing** (off by default): when the natural next command would jump
+  over the 2-unit window, force the post-command distance to 37 by writing the
+  vertical velocity. It needs both the authoritative server velocity and the
+  client prediction velocity:
+  - server `CBaseEntity::m_vecAbsVelocity` (datamap offset 0x228), read by
+    `SetupMove` via `GetAbsVelocity`;
+  - client `C_BaseEntity::m_vecAbsVelocity` (datamap offset 0x11C) and the
+    networked `m_vecVelocity` (0xE0 + 8).
+  The velocity is `dz / 0.015 + 0.5 * 600 * 0.015` where `dz` is the required
+  displacement for this command. This turns the ~20% timing success at 625 ups
+  into a repeatable setup, at the cost of one command with a nudged vertical
+  speed. Pure jumpbug remains available with Assist off.
+- The server datamap has two `m_vecVelocity` entries (0x1C and 0x29C), so the
+  assist deliberately writes only `m_vecAbsVelocity`; `SetAbsVelocity` syncs
+  `m_vecVelocity` after the command.
