/**
 * The zero-value constructor of {@link RunState}, the run loop's ONE shared mutable record (seven groups,
 * sixty fields; its writers are the run loop's three top-level machines, see the interface's own doc in
 * contracts.ts). The driver mints one per run leg and hands it to every machine as a `borrowed-mutable`
 * seat; nothing here reads or writes host state, so the skeleton is machinery, not a phase.
 *
 * Named without the `run-` family prefix on purpose: that prefix marks a DRIVEN run lane (one the driver
 * calls with an Input and reads a Result from — the phase-api gate judges every such file), and the
 * layering registry's run-lanes stratum is a glob over the same prefix. A machinery module the lanes stand
 * on sits one layer below them under a name of its own, exactly as the prepare-path machinery does.
