/**
 * PrepareTask's QUESTION-FACE phase, verbatim from the driver: the leg's ONE checkpoint-store
 * read, the durable mandate as it binds at the question seat, the content-ask binding table (with the leak
 * bound the routing lane checks against — the constant below), the stranded-answer disclosure and the leg-end
 * settle, the three-way mount decision (live face / durable face / override), and the AskUserQuestion mount
 * with its redeemed-approval, posture, fallback and synthetic-continuation arms. The interface is the
 * dependency list the segment had implicitly.
 *
 * SYNCHRONOUS FUNCTION, SYNCHRONOUS CALL: the stretch has no await, so the phase adds no yield between the
 * offload-reader mount before it and the scheduler mount after it (a stretch with no await
 * is extracted as a sync function — an `async` wrapper would open a microtask window). Read-stability of the
 * host handles for the call: {@link RunInternals} (`@contract prepare.deps-read-stable`).
 *
 * One seat is a LIVE GETTER: the inherited-unavailable marker set is declared by the driver's
 * gate-fold section AFTER this phase and read per call at RUN time, so it enters as `() => ReadonlySet` — a
 * read before the driver declares it throws (temporal dead zone), which is the fail-loud an uninitialized
 * live read owes.
