/**
 * Stone specialist registry — the auditability contract.
 *
 * Each Stone declares the **complete inventory** of specialists it
 * could fire on a query, along with the FSM step name (used to join
 * against the run trace) and a one-line skip reason for when a
 * specialist is absent from a particular run.
 *
 * v0.4.5 §3: every Stone's expander shows the full intended roster,
 * never a filtered subset. A reader who expands a Stone sees what
 * could have happened *and* what did. Specialists missing from the
 * run output render as `not_invoked` with their registered skip
 * reason.
 *
 * The display name and FSM step name often differ (the trace emits
 * `mta_entrance_exposure`, the FSM action is `step_mta_entrances`,
 * the Findings adapter writes state key `mta_entrances`). The
 * `stepNames` list maps the registry entry to all variants the
 * trace might emit so we don't double-count or miss matches.
