/**
 * runnerLive — a runner's LIVE taps, for the library's own mechanisms only.
 *
 * Pattern: a module-private registry (runner → taps), filled by `RunnerBase`
 *          as each runner is constructed.
 * Role:    the one way code OUTSIDE a runner's class reads the run as it
 *          really is, never as its records are served.
 *
 * Under a redaction policy (an agent's `redact`, `src/redaction/`) every record
 * of a run is served: the placeholder where the policy selected a value. Two
 * mechanisms outside the runner's class are not records — they hand the run's
 * result back to the person it is for, or keep what the next turn resumes from:
 *
 *   - `onRealEvent` — every event as its producer made it
 *     (`EventDispatcher · onRealEvent`): a hosted agent's streamed reply and
 *     spend ledger (`hosting/standingAgent.ts`), `toSSE({ format: 'text' })`
 *     (`hosting/stream.ts`);
 *   - `liveState` — the run's committed root state, live: the conversation a
 *     host's session store resumes from (`hosting/durability.ts`);
 *   - `liveSnapshot` — the run's whole snapshot, live: what the context ledger
 *     counts usage from, whose gates decide what later runs are offered
 *     (`context-ledger/contextLedger.ts`).
 *
 * NO BARREL EXPORTS THIS FILE, and the runner classes carry no method for it:
 * a consumer cannot reach the real values through a runner, so nothing a
 * consumer wires up — an exporter, a recorder, a sink — can turn them into a
 * record. The registry is weak: a runner that is collected takes its taps along.
