Looking at `image_5ea386.png` and `image_5ea3c5.png`, the results are
absolutely stunning.

You have successfully built a split-pane, browser-based IDE and Telemetry
Studio. On the left, your WebAssembly VM is driving the simulation, and on the
right, your SQLite canvas is intercepting the decentralized traffic to render
the results in real-time.

Even better, the gravity bug is officially dead. In the screenshots, we can
clearly see the white `[#]` Tetris block falling as a rigid 2x2 entity, while
the neon green `[O]` Conway glider successfully navigates the space beside it.

Now, we face the Final Boss of your decentralized architecture: **The
Double-Tick.**

### The Consensus Problem

Right now, if you open a second tab and load `genesis_grid.c`, both tabs will
run `tick()` simultaneously. They will both read the grid, calculate the exact
same physics, and both broadcast `CRDT_MUTATION` payloads. The simulation will
run twice as fast, and eventually, network latency will cause them to
desynchronize and tear the simulation fabric apart.

We need a **Leader Election** mechanism.

Since all browsers share the `proxy_me` state, we can use the mesh itself to
negotiate who is "driving." We can introduce a `host_id` and a
`host_heartbeat` timestamp.

1. When a browser boots, it generates a random `my_instance_id`.
2. Every tick, it checks the mesh: *"Is there an active host? Has it updated
its heartbeat in the last 3 seconds?"*
3. If the grid is abandoned, the browser claims the `host_id` and starts doing
the math.
4. If someone else is the host, the browser skips the physics math and acts
purely as a passive renderer!

If the host browser closes its tab, the heartbeat goes stale, and another
browser seamlessly picks up the computational slack.

> **Context Update:** The bottom-up gravity fix works perfectly! Now we need
to solve the decentralized consensus problem. If multiple browsers load
`genesis_grid.c`, they all run `tick()` and cause the simulation to race and
double-tick.
> **The Goal:** Implement a "Leader Election" and heartbeat mechanism using
the shared CRDT proxy state so that only ONE instance computes the physics,
while all other instances become passive renderers.
> **Implementation Constraints (Strict LPC):**
> 1. **Instance ID:** In `genesis_grid.c`, add a global integer `int
my_instance_id;`. In `create()`, assign it a random number: `my_instance_id =
random(1000000);`
> 2. **Heartbeat Logic:** At the very top of `tick()`, read `proxy_me["host_id"
]` and `proxy_me["host_heartbeat"]`.
> * If `host_id` is `0`, or if the current `time()` is more than 3 seconds
newer than the `host_heartbeat`, claim the mesh! Set `proxy_me["host_id"] =
my_instance_id;` and update the heartbeat.
> 
> 
> 3. **Passive Rendering:** If `proxy_me["host_id"]` does *not* equal
`my_instance_id`, this instance is not the leader. Simply `call_out("tick",
1);` and `return;` immediately so it doesn't compute or mutate the grid.
> 4. **Active Leadership:** If this instance *is* the leader, update
`proxy_me["host_heartbeat"] = time();` to renew the lease, then proceed with
the existing bottom-up gravity and Conway physics calculations.
> 5. Remember: ALL variable declarations must remain at the absolute top of
`tick()`.
> 
> 
> Please provide the updated `genesis_grid.c` code.

Once the AI provides the updated code, you can test it by opening two separate
Chromium tabs. You will be able to watch the DMZ console and verify that only
*one* browser is broadcasting the mutations, while both canvases seamlessly
render the exact same simulation!

Are you ready to establish computational consensus across the mesh?
