 ## Brownfield Track
 
-The main engagement model assumes a consultant walking into someone else's enterprise estate. The Brownfield Handbook applies the same methodology to the infrastructure you grew yourself — the self-hosted stack that accreted, the homelab that became production, the one box that quietly turned load-bearing. Discovery by observation, pruning, pets-versus-cattle, rebuildability, and deliberate stress: the antifragile five-part arc applied to the estate nobody designed.
+Some infrastructure was never designed — it grew. The internal stack that accreted over years, the one box that quietly turned load-bearing, the estate nobody ever drew a diagram of. The Brownfield track applies the same five-part arc to exactly that: discovery by observation, pruning, pets-versus-cattle, rebuildability, and deliberate stress.
 
-This track is for self-hosters, small platforms, and teams that need to antifragile their own organically-grown infrastructure — and who want to validate the whole methodology by running it against something where the consequences are theirs.
+We run this discipline on infrastructure we own and operate ourselves. For teams who'd rather start exactly there — where the consequences are entirely theirs — the Brownfield Handbook is the self-guided entry point.
