+## Challenge
+
+| Row | |
+|---|---|
+| **Challenge** | Build a Rust exact-diagonalization / full-configuration-interaction workbench for electronic-structure method development, with determinant-based arbitrary-order coupled cluster as the mandatory showcase. |
+| **Catalog issue** | Addresses #129 — "Exact diagonalization workbench in Rust for electronic structure method development", released by Guo CHEN. |
+| **Track** | `ed`, from the issue's `Method` field: Exact Diagonalization. |
+
+## Working Repository
+
+Development starts in the private AGPL-3.0 repository
+`JunkaiWang-TheoPhy/quantum-harness-129-workbench-rust`.
+
+## Companion Rust Registrations
+
+This is the main Rewrite It In Rust! workbench registration. The related Rust
+infrastructure and writing tracks are registered separately:
+
+- #214 — `tenferro-rs` verification from ED/FCI workloads.
+- #215 — Rust port of the #71 Occam's Circuit verifier workflow.
+- #216 — Rust-inspired certified tensor DSL design.
