Own your inference harness; better yet, own the model layer too for full control.

Architectural principle relevant to building on personal platforms and agents, though brief and motivational rather than actionable how-to.

Hierarchical persistent agent teams (CTO, CMO roles) delegate session management; reduces cognitive overhead and ships 5x more PRs.

Direct pattern for scaling agent work—moving from micromanaging tasks to delegating to higher-level orchestrators transfers cleanly to OpenC
