The website pages arrived from the full RFC 004 branch and documented the
memory op-log, `mempalace oplog`, and automatic bidirectional memory
convergence. None of that is in this slice: the CLI has logstream, artifact,
and replica, and memory moves by one-way `replica pull`.
- cli.md: drop the `mempalace oplog` section (the command does not exist);
note that full convergence is staged.
- replicated-palace.md: split the sync table into shipping (coordination,
multi-master) vs next (memory ops, bidirectional); say plainly that two
machines capturing independently do not merge yet.
- shared-brain.md: mark step 3 a pull you re-run, not a converging loop.
- RFC 004: record which steps landed.
