子步骤状态及推进关系

策略的具体实现如下。

reportedStepStatusCatalog = {
  /** No status reported yet; only `fix` uses this as an intermediate state. */
  unknown: {
    terminal: false,
    next: ['unknown', 'planned', 'running', 'success', 'error', 'cancelled', 'skipped'],
  },
  /** Declared by the node but not started. */
  planned: {
    terminal: false,
    next: ['planned', 'running', 'success', 'error', 'cancelled', 'skipped'],
  },
  /** Started and still active; may only stay running or finish. */
  running: { terminal: false, next: ['running', 'success', 'error', 'cancelled'] },
  success: { terminal: true, next: [] },
  error: { terminal: true, next: [] },
  cancelled: { terminal: true, next: [] },
  skipped: { terminal: true, next: [] },
} as const
