# Reproduce the recorded Tic-Tac-Toe rule test

This is a synthetic example, not customer or productivity evidence. Source snapshot: 6fd224e5843e4e29ca2b87cc4329bb8084a7a624. Bundle: tic-tac-toe-6c61ff3dd6d5d15b.

## Run the check

Extract the archive into an empty directory. With Node.js 24 available, run:

```sh
node --test game.test.js
```

The existing single test asserts an X win, completed-board locking, and a reset's next player. It does not explicitly assert draws, occupied-cell rejection, every win line, or invalid indices. A passing test does not prove those behaviors.

## Inspect the work agreement

Read workflow-evidence.json for the recorded request, task and summary excerpts, historical command transcript, and reconciliation excerpt. These are historical demonstration records, not a complete fresh workspace or a currently replayed Day Shift lifecycle. They name paths from the original synthetic repository; game.js and game.test.js here are the runnable published files.

## Continue the work

A possible next task is adding explicit draw and input-boundary tests. Review the existing scope and implementation before that change. This is a suggested handoff, not an observed second-agent session. Current Day Shift procedures live at https://docs.tnsds.tech/workflows/.
