# Stale-location incident

> Run a deterministic memory failure from capture through diagnosis, replay, and regression.

The repository includes a credential-free reference incident that stores an old city, records a correction, and deliberately retrieves the stale record.

## Run the complete example

```bash theme={"dark"}
git clone https://github.com/Meyk0/engram-viz.git
cd engram-viz
npm install
npm run engram -- demo stale-location
```

That one command initializes local capture, starts Studio, records the three
turns, and opens the Incidents workspace. It uses no live model or provider.

To exercise the instrumented Mem0-shaped fixture manually, start Studio and run
the fixture in another terminal:

```bash theme={"dark"}
npm run engram -- dev
npm run engram -- run -- node examples/mem0-stale-correction/demo.mjs
```

## Diagnose the answer

1. Open `http://localhost:3100/?mode=incidents`.
2. Select the recorded `What city do I live in now?` turn.
3. Enter `Oakland` as expected answer evidence.
4. Review why the stale San Francisco memory was selected.
5. Apply the proposed branch repair.
6. Replay the frozen turn.
7. Export the passing regression artifact.

## Run the checked-in regression

```bash theme={"dark"}
npm run engram -- test \
  regressions/current-city.engram-test.json \
  --executor examples/mem0-stale-correction/regression-executor.mjs \
  --format github \
  --output engram-regression-report.json
```

The example is intentionally deterministic. It tests Engram's incident workflow without claiming equivalence to a live memory provider or model.
