I will now generate the updated INSTRUCTIONS.md file designed for OpenCode. This instruction document sets up a fully standalone, zero-maintenance Kubernetes cluster using Talos Linux, Forgejo (for local Git hosting), ArgoCD (for GitOps deployment), and Longhorn (for replicated storage over the Thunderbolt interconnect).

I have generated the INSTRUCTIONS.md file tailored specifically for your standalone Talos + Forgejo + ArgoCD architecture.

What this document achieves for OpenCode:

1. Defines clear boundaries: Explicitly instructs OpenCode to build using declarative manifests instead of ad-hoc imperative commands.
2. Handles the Kip-of-het-Ei challenge: Outlines the 3-phase bootstrap approach (Talos Bootstrap $\rightarrow$ Core Services $\rightarrow$ Full GitOps Autonomous Mode).
3. Enforces Thunderbolt optimization: Ensures storage replication (Longhorn) uses the Thunderbolt interface for maximum speed and lowest latency.

You can drop this file directly into your project directory and let OpenCode begin with Phase 1!
