Five rungs from a chatbot to a harness. The model stays the same at every rung — what grows up is the system around it.
Governance, scheduling, sub-agents, audit. AI as infrastructure, not a tool.
Domain facts, past decisions, customer context — like a veteran teammate.
Reusable team procedures — acts like someone who's done this before.
Reads your files, runs commands, opens PRs. Acts inside your environment.
Answers questions in a vacuum. Generic knowledge, no tools, no context — copy-paste is the integration.
L1 is a model with hands and no rails — power without containment. L4 is the same model, harnessed: scoped, observed, governed, and safe enough to operate as infrastructure instead of a tool.
