4//! Virtual machine that executes the instruction stream emitted by the planner. The VM owns the per-request
5//! lifecycle (admin, command, query, subscription), threads parameters through, walks the plan, dispatches each
6//! instruction to its handler, and returns the resulting columns or change deltas to the caller.
7//!
8//! Instruction handlers live alongside the VM so the dispatch table is the single place that decides what an
9//! opcode does. Adding a new instruction means writing a handler and wiring it in - planner output never reaches
10//! storage without first being interpreted here.
