+# 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.
