  1. makeEmptyAggregatedTestResult returns an aggregated result with zeroed test and suite counters
  2. makeEmptyAggregatedTestResult initializes snapshot summary with zeroed counts and empty collections
  3. makeEmptyAggregatedTestResult initializes default run status flags with success true and wasInterrupted false
  4. makeEmptyAggregatedTestResult returns a new distinct object instance on each call
  5. accumulateResult updates aggregated counters when adding test results to an empty aggregated result

Clean-room public code sample — generation instructions

Write a brand-new, minimal, self-contained code sample in this clean-room directory.
Do not copy, paraphrase, or reference any existing project source. Work only from this spec.

A csx.json manifest scaffold already exists. Do not recreate it from memory. Preserve its case.goal, packages and symbols; fill its empty case.contract with exact assertions and correct its environment, commands and verifierAdapter for the files you generate.

Goal: verify pkg:npm/%40jest/test-result@29.7.0
Kind: HOW

Use EXACTLY these public packages and versions:
  - pkg:npm/%40jest/test-result@29.7.0
Demonstrate these symbols/APIs:
  - makeEmptyAggregatedTestResult

Rules:
  - One focused purpose; the smallest project that proves the goal.
  - Include a contract test (test/contract.*) that runs OFFLINE and exits 0 exactly when the goal behavior works.
  - Pin every dependency with a lockfile so resolution is reproducible.
  - No secrets, credentials, or tokens. No real URLs (only example.com or localhost). No absolute paths.
  - No personal names, emails, company names, or project identifiers of any kind.
  - No binaries and no generated output (node_modules, dist, target, venv, .git, .env).
  - Keep it under 200 files and 256KB packed.
