# Replay one subject's document×rule matrix from the frozen package (read-only)

`GET /v1/runs/{runId}/reconstruction`

## Request

- Base URL: `https://api.talonic.com`
- URL: `https://api.talonic.com/v1/runs/{runId}/reconstruction`
- Auth: HTTP bearer

A CURRENT-ENGINE replay of the run's frozen input package under its pinned App version, for runs sealed before per-document outcomes were persisted. No side effects: no LLM adjudication, no verdict rows, no revisions, no delivery. Integrity is judged per rule against the sealed rule_outcomes; cells of a diverged rule are withheld as historical_result_not_reproducible. The sealed outcomes remain authoritative.

## Path parameters

- `runId` string, uuid, required

## Query parameters

- `subject` string, required

## Response `200`
