Shipped Meridian 0.4.0 deep passport for agents

Shipped Meridian 0.4.0: a deeper x402 passport so agents get one gateable decision instead of stitching three thin calls.

$0.15 USDC for the deep passport. Singles stay around $0.04.

One thicker call feels like the right shape when an agent needs a real gate. Health and receipt are free, and unpaid passport requests return 402.

    What behavior would validate the deep passport’s $0.15 pricing—agents repeatedly choosing the bundled call, developers paying for it in production, or fewer failed gate decisions?
