+| Plan | `docs/plans/NEO-60-implementation-plan.md` |

+
+## Preconditions
+
+- Server built and configured with default `Content:ResourceNodesDirectory` pointing at repo `content/resource-nodes` (local dev / `InMemoryWebApplicationFactory` tests use the same layout).
+
+## Checklist
+
+1. Start **`NeonSprawl.Server`** (e.g. `dotnet run` from `server/NeonSprawl.Server`).
+2. **`GET /game/world/resource-node-definitions`** — expect **200** and **`Content-Type`** containing **`application/json`**. Example (default dev URL from `Properties/launchSettings.json` and Bruno `environments/Local.bru`; change the host/port if yours differs):
+
+   ```bash
+   curl -sS -i "http://localhost:5253/game/world/resource-node-definitions"
+   ```
+
+3. Parse JSON — expect **`schemaVersion`** === **1**, **`nodes`** array length **4**.
+4. Confirm **`id`** values match the frozen prototype four in ordinal order: **`prototype_bio_mat_gamma`**, **`prototype_resource_node_alpha`**, **`prototype_subsurface_vein_beta`**, **`prototype_urban_bulk_delta`**.
+5. Spot-check **`prototype_resource_node_alpha`**: **`displayName`** “Prototype Salvage Heap”, **`gatherLens`** **`consumer_salvage`**, **`maxGathers`** **10**, **`yield.itemId`** **`scrap_metal_bulk`**, **`yield.quantity`** **1**.
+6. Spot-check **`prototype_urban_bulk_delta`**: **`gatherLens`** **`urban_bulk`**, **`yield.quantity`** **5**.
+7. Optional: run **`bruno/neon-sprawl-server/resource-node-definitions/Get resource node definitions.bru`** against the same **`baseUrl`** (see `environments/Local.bru`).

 **`IResourceNodeDefinitionRegistry`** (NEO-59) is the preferred lookup surface for gather engine, depletion, interact, and HTTP callers — resolve node defs and yield rows by **`nodeDefId`**, enumerate defs in id order. The catalog singleton remains for fail-fast startup only; do not inject **`ResourceNodeCatalog`** in new game code.
 
+## Resource node definitions (NEO-60)

+**`GET /game/world/resource-node-definitions`** returns a versioned JSON body (`schemaVersion` **1**, **`nodes`**) backed by **`IResourceNodeDefinitionRegistry`** — the same prototype rows loaded at startup (no second source of truth). Each row includes **`id`**, **`displayName`**, **`gatherLens`**, **`maxGathers`**, and nested **`yield`** (`itemId`, `quantity`).
