+# Manual QA — NEO-41 (gather → skill XP via interact)
+
+Reference: [implementation plan](../plans/NEO-41-implementation-plan.md), [NEO-38](./NEO-38.md) (skill progression grant), [NEO-9 README — Interaction](../../server/README.md#interaction-neo-9).
+
+## Preconditions
+
+- Run `NeonSprawl.Server` from `server/NeonSprawl.Server` (`dotnet run`; default `http://localhost:5253`).
+- Player **`dev-local-1`** (default seed).
+
+```bash
+BASE=http://localhost:5253
+ID=dev-local-1
+```
+
+## Move in range of the prototype resource node
+
+Anchor **(12, −6)** on X/Z, radius **3** m. Example stand at **(10, −6)**:
+
+```bash
+curl -sS -i -X POST "${BASE}/game/players/${ID}/move" \
+ -H "Content-Type: application/json" \
+ -d '{"schemaVersion":1,"target":{"x":10,"y":0.9,"z":-6}}'
+```
+
+Expect **HTTP 200**.
+
+## Baseline skill progression (optional)
+
+```bash
+curl -sS "${BASE}/game/players/${ID}/skill-progression"
+```
+
+Note **`salvage`** **`xp`** (often **0** on a fresh store).
+
+## Gather interact (prototype)
+
+```bash
+curl -sS -i -X POST "${BASE}/game/players/${ID}/interact" \
+ -H "Content-Type: application/json" \
+ -d '{"schemaVersion":1,"interactableId":"prototype_resource_node_alpha"}'
+```
+
+Expect **HTTP 200**, **`allowed`:** **true**.
+
+## Verify XP
+
+```bash
+curl -sS "${BASE}/game/players/${ID}/skill-progression"
+```
+
+**`salvage`** **`xp`** should increase by **10** per successful gather interact (repeat interact to see cumulative XP).
+
+## Control — terminal does not grant gather XP
+
+Move near **`prototype_terminal`** (e.g. target **`0.5`, `0.9`, `0.5`**), **`POST …/interact`** with **`prototype_terminal`**, then GET progression: **`salvage`** XP should match whatever you had before this control (no +10 from terminal alone).

-- [ ] Disallowed `sourceKind` / skill combinations **never** emitted from gather (defensive: only `salvage` + `activity` for `resource_node` kind; registry check before apply).
-- [ ] Visible or **testable** progression: automated test (and manual QA) shows **`salvage`** XP increases after successful **`resource_node`** interact from in-range position.
