@parmana/replay

[PARTIAL]. Real semantic re-evaluation, for one execution at a time, not reachable from POST /replay or any other route. See Replay for the full disambiguation from the unrelated POST /replay route.

Purpose

Re-runs PolicyEngine.evaluate() against a trust record’s recorded signals and compares the outcome to what was originally decided, this is genuine semantic verification, not a signature or hash recheck.

Install

Not published to npm. This is an internal package of this repository, used from a clone of it: npm ci at the repository root links every workspace package. The packages published to npm are @parmana/sdk, @parmana/connector-sdk and @parmana/sign.

Key exports

Export	Stability
`ReplayEngine`	[PARTIAL]. `.replay(input: ReplayInput): ReplayResult`. Real `PolicyEngine` re-evaluation, scoped to `trustRecord.executions[0]`, one execution, not the whole record.
`ReplayBuilder`	[AVAILABLE]. `.build(): ReplayEngine`
`ReplayVerifier`	[AVAILABLE]. `.verify(original, replayed): boolean`, deep-equality via `JSON.stringify` comparison
`ReplayPipeline`, `ReplayExecutor`, `ReplayPlan`	[AVAILABLE]. Build and run a multi-step replay plan from recorded execution IDs
`ReplayError`	Thrown on an invalid or incomplete trust record

`ReplayResult` shape

interface ReplayResult {
  recordedDecision: Decision;
  replayedDecision: Decision;
  matches: boolean; // recordedDecision.outcome === replayedDecision.outcome
  replayedAt: string;
}

Minimal example

import { ReplayEngine } from "@parmana/replay";

const engine = new ReplayEngine();
const result = engine.replay({ trustRecord, transaction, policy });
// result.matches === true if the recorded and re-evaluated outcomes agree

Full runnable version: examples/tutorials/06-replay/run.ts.

Not reachable from the server. Confirmed by grep: nothing in packages/api or packages/runtime imports @parmana/replay. POST /replay is an unrelated route, a signature recheck via ExecutionTrustApplication.replay(), see REST API Introduction. Don’t assume calling the HTTP route exercises this package.
