/** * 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. */ import type { RuntimeSnapshot } from 'footprintjs'; import type { AgentfootprintEvent } from '../events/registry.js'; import type { Unsubscribe } from '../events/dispatcher.js'; /** What the library reads live from a runner. */ export interface RunnerLive { /** Subscribe to every event as its producer made it — never served. */ onRealEvent(listener: (event: AgentfootprintEvent) => void): Unsubscribe; /** The current (or last) run's committed root state, live and unserved; O(1). */ liveState(): Readonly<Record<string, unknown>> | undefined; /** The current (or last) run's snapshot, live and unserved. */ liveSnapshot(): RuntimeSnapshot | undefined; } /** Register `runner`'s live taps — `RunnerBase` does, once per runner.
