# IB-WP-0011 — Pruned Legacy Reference Pilot

## Goal

Migrate a small representative slice of
`markitect-main/examples/infospace-with-history` into `infospace-bench` to prove
successor behavior against real legacy content.

## Tasks

### T01 — Select representative slice

```task
id: IB-WP-0011-T01
status: done
priority: high
state_hub_task_id: "49d4865b-38b0-4994-a0f9-1cbdf718689c"
```

- Choose one or two source chapters or a compact equivalent fixture
- Include at least one entity, one relation, one evaluation, and one metrics
  snapshot
- Avoid committing generated bulk

### T02 — Migrate schemas/contracts and methodology

```task
id: IB-WP-0011-T02
status: done
priority: high
state_hub_task_id: "3bea0589-cd48-4a12-b2c5-e8996d383195"
```

- Convert relevant legacy schemas into `markitect-tool` contracts or supported
  validation artifacts
- Preserve metrics methodology where still applicable
- Document changes from the old experiment

### T03 — Run successor pipeline

```task
id: IB-WP-0011-T03
status: done
priority: high
state_hub_task_id: "fe012682-7af3-42a0-8d14-07685a663242"
```

- Load, validate, inspect, evaluate, and report on the migrated pilot
- Compare outputs against expected legacy behavior
- Capture gaps as follow-up tasks

### T04 — Publish migration report

```task
id: IB-WP-0011-T04
status: done
priority: medium
state_hub_task_id: "5a6c885f-6acb-4d18-9aff-f710423e0198"
```

- Add a report under the pilot's `reports/`
- Include what was replaced, what was delegated, and what remains missing
- Use the report as evidence for replacement readiness

## Acceptance

- A legacy-derived pilot exists under `infospaces/`
- It exercises parser, validation, entity/relation, evaluation, metrics, and
  graph features
- Its migration report is explicit about parity and gaps
