/**
 * Admission bookkeeping for HUMAN INPUTS accepted mid-run: the per-leg ordinal an accepted input is stamped
 * with, and the acceptance frame's once-only seat. Two accepting arms share the ordinal — the stream's `steer`
 * verb and the run body — which is why it is keyed on the leg's harness in a module-level WeakMap rather than
 * held by either arm: one counter per leg, one ascending sequence across both. Also the stream verbs' typed
 * refusal. (Whether a repeat under a used `inputId` is the same instruction is steer-replay.ts's one judgement,
 * shared with the parked queue.)
 *
 * Run-loop machinery (layer 1), not a driven lane: nothing here takes an Input or hands back a Result, and
 * nothing here reads host state. Named without the `run-` family prefix for that reason.
