# Retire Haskell/IHP infrastructure after Core Hub cutover

Remove the Haskell dependency from the production interaction framework after the replacement is proven.

## Retire Probe Repo

```task
id: CORE-WP-0007-T01
status: todo
priority: medium
state_hub_task_id: "d3a494a3-dc23-491f-af32-1d19120b3aae"
```

Rename or archive the low-risk IHP probe repo first, preserving any useful notes about the failed build/deploy path.

## Rename Production Inter-Hub Repo

```task
id: CORE-WP-0007-T02
status: wait
priority: high
state_hub_task_id: "16eb7ce3-b574-4667-a189-c14ff5d0502b"
```

Rename `inter-hub` to `inter-hub-haskell` only after Core Hub compatibility, migration, and production cutover gates pass.

## Decommission Haskell Build Lane

```task
id: CORE-WP-0007-T03
status: wait
priority: medium
state_hub_task_id: "bea9943c-916f-402f-a6d9-7907bb48137c"
```

Retire or park haskelseed runner labels, Haskell build-agent capability, IHP/GHC/Nix/devenv docs, and build-machine workplans after no active repo needs them.

## Update Cross-Repo References

```task
id: CORE-WP-0007-T04
status: wait
priority: medium
state_hub_task_id: "ed7f8e01-5305-465c-8bfc-04bc47bfdf40"
```

Update docs and workplans in consuming repos so Inter-Hub references point to Core Hub or explicitly to `inter-hub-haskell` for historical context.
