From b810d1ddca0c4c986c327b259198ed3b0783adc3 Mon Sep 17 00:00:00 2001 From: Lex Christopherson Date: Mon, 12 Jan 2026 14:32:54 -0600 Subject: [PATCH] fix(execute-phase): add one-subagent-per-plan constraint Context isolation is the primary goal, not parallelization. Even sequential plans spawn separate subagents for fresh 200k context.
