Two coupled gaps from tracing a real run: 1. Freestyle implements in phase 2 via stages compiled from the architect's execution_plan (ExecutionPlanCompiler sets allowedTools = stage.tools), so the static allow-lists never reach it and architect_freestyle.md banned every tool but the file four. Teach the architect to thread an analysis-referenced task through the plan: implementing stages get task_context/task_update and claim + submit_for_review; the final/review stage completes it. No task referenced → no task tools, and the plan never creates one. 2. Give the analyst task_create so the work is framed as a tracked item up front (role_pipeline + freestyle). "Read-only" for the analyst means it writes no files; a task is an event-log entry, not a file write — task_create is T2, so opening one is approval-gated. The analyst names the new id in the analysis so the implementer claims it and the reviewer completes it; the implementer now creates only as a fallback.
