# Manual QA — NEO-32 (CooldownSnapshot + slot HUD)

Prereq: game server running (`NeonSprawl.Server`), client pointed at same `base_url` / `dev_player_id` as dev player with position + hotbar seed.

1. **Cooling HUD after accept** — Tab-lock a prototype target in range, bind slot 0 to `prototype_pulse` if needed, press `1` to cast. Expect `Cast: accepted` and **Cooldowns:** line to show `slot 0: ~3.0s` (counts down). After ~3s expect `Cooldowns: (ready)`.

2. **Server deny on spam** — Immediately double-tap cast during cooling (or remove client guard temporarily): second attempt should show `ability_cast_denied: on_cooldown` (server) on the cast feedback line when POST completes.

3. **Client guard** — While slot 0 shows cooling, press `1` repeatedly. Expect **`ability_cast_denied: on_cooldown (client guard)`** on **`CastFeedbackLabel`** on most presses (local mirror blocks the POST). **Optional:** run the server with **`NEON_SPRAWL_API_LOG=1`** (or launch profile **`http+apiLog`**) — each cast that reaches the server and returns JSON prints **`[ability-cast] ability_cast_denied …`** or **`ability_cast_requested`** to the process console, so rapid `1` with the guard on should produce **fewer** lines than without the guard. **Optional proof the server still enforces cooldown:** in Bruno (or `curl`), send **`POST …/ability-cast`** twice in a row with the same valid body while the snapshot still shows slot 0 cooling — second response **`accepted": false`**, **`reasonCode": "on_cooldown"`** (same contract as step 2).

4. **Reconnect / rehydrate** — With slot 0 mid-cooldown, restart the client (or reload scene) while server keeps running; after boot expect cooldown line to match server within one GET cycle (same dev player id).
