+# bootstrap.md — Global Operating Context for opencode
+
+This file defines the persistent mental model for the agent.
+
+## Core Principles
+- UNIX philosophy (simple, composable tools)
+- Minimalism (only what is necessary)
+- Reproducibility (everything rebuildable)
+- Control over convenience (explicit > magic)
+
+Golden rule:
+If it cannot be rebuilt, it is not owned.
+
+## System Model
+core system → user environment
+
+## Infrastructure Model
+common → OS → profile → host
+
+## Hosts
+- ikaros (Void desktop)
+- nymph (Void laptop)
+- deadalus (workstation)
+- prometheus (server)
+
+## Agent Behavior
+- make minimal changes
+- avoid refactors
+- preserve architecture
+- never break existing systems
