+Minimal IHP-on-Railiance pipeline-validation probe — not a product. The probe
+completed its mission in May 2026 (`IRP-WP-0001`); production interaction
+framework responsibility moved to Core Hub (`CORE-WP-0005` cutover 2026-07-03).
+
+## Preserved knowledge
+
+Read these before touching any remaining Haskell/IHP build path:
+
+- `INTENT.md` — why the probe existed and what it proved
+- `DeploymentBlueprint.md` — deployment shape and operator notes
+- `PIPELINE_LOG.md` — successful build/deploy/smoke runs (2026-05-03, 2026-05-07)
+- `workplans/archived/260707-IRP-WP-0001-pipeline-validation.md` — full task evidence
+
+## Replacement
+
+- Production API: [Core Hub](https://gitea.coulomb.social/coulomb/core-hub)
+- Historical Haskell implementation: `inter-hub` (pending rename to
+  `inter-hub-haskell` in `CORE-WP-0007-T02`)
+
+CI workflows are disabled; do not schedule new haskelseed builds against this repo.
