/**
 * The single legitimate gateway for replicated state mutations.
 *
 * On `execute(action, sender_id)`:
 *   1. Iterate `action.affected_components((entity_id, component_class) => ...)`.
 *      For each, look up the live component on `world`, look up its replication
 *      adapter via the binary registry, and write
 *      `(entity_id, component_type_id, payload_len, payload)` into the current
 *      frame's `ActionLog` buffer.
 *   2. Call `action.apply(world)`.
 *   3. Append `(action_type_id, sender_id, action_payload_len, action_payload)`
 *      to the same frame's buffer. `sender_id` is the peer that originated
 *      the action — used by rollback orchestrators for stable-sort tie-
 *      breaking when reconstructing per-tick action order. Defaults to
 *      {@link SENDER_LOCAL} for actions generated by this peer.
 *
 * Code outside the executor that wants to mutate replicated state is doing it
 * wrong: such mutations will not be replicated, will not be reversible, and
 * will desync clients on rollback. Use a `SimAction`.
