Excellent. The live hot-reloading proves the distributed mesh is working
perfectly.
Here is the exact prompt and response you can expect from the "Contributor" AI
for the second routine. You can copy the code block directly into your REPL to
deploy it.
Your Input to the Contributor:
> Please build this routine:
> Name: omega_ftr_market_purchase
> Purpose: Handles a player buying an upgrade. Verifies the market cost
against the player's budget, deducts funds, and adds the item to their
inventory.
> Contract Requires: ['world.market', 'players.[id].core', 'players.[id].invent
ory']
> Contract Mutates: ['players.[id].core', 'players.[id].inventory']
> Intent Payload: { "playerId": "taco_bot", "item": "michelin_special" }
> 
The Contributor's Output:
const marketPurchase = async (params) => {
    const { state, intent } = params;
    const { playerId, item } = intent;

    // Construct exact dot-notation keys
    const marketKey = 'world.market';
    const coreKey = `players.${playerId}.core`;
    const invKey = `players.${playerId}.inventory`;

    // Extract state slices
    const market = state[marketKey];
    const core = state[coreKey];
    const inventory = state[invKey];

    // Failsafe: Ensure state exists
    if (!market || !core || !inventory) {
        return { mutatedState: {}, events: ['ERROR_STATE_MISSING'] };
    }

    const cost = market.costs[item];

    // Failsafe: Ensure item is valid
    if (cost === undefined) {
        return { mutatedState: {}, events: ['ERROR_INVALID_MARKET_ITEM'] };
    }

    // Failsafe: Check budget
    if (core.budget < cost) {
        return { mutatedState: {}, events: ['PURCHASE_FAILED_INSUFFICIENT_FUNDS
'] };
    }

    // Process the purchase transaction
    core.budget -= cost;
    inventory[item] = (inventory[item] || 0) + 1;

    // Return only the authorized keys defined in the mutates contract
    return {
        mutatedState: {
            [coreKey]: core,
            [invKey]: inventory
        },
        events: [`PURCHASE_SUCCESS_${item.toUpperCase()}`]
    };
};

await saveAs('omega_ftr_market_purchase', marketPurchase, {
    state: { type: 'object', required: true },
    intent: { type: 'object', required: true }
});

The logic extracts the dynamic keys based on the playerId passed in the intent
payload. It performs strict validation checks on the budget and the market
price catalog before mutating the data. Because it runs as a pure function, if
any failsafe trips, it simply returns the error event without mutating the
state, ensuring the filesystem remains untouched.
Let me know when that successfully hot-reloads, and we will move to the
combat/interaction mechanic: omega_ftr_launch_event.
