For resumed Build work, load the existing task artifact before editing. Continue the lowest-numbered incomplete plan phase unless the user or plan explicitly selects another phase. ## What To Load **Foundation** (confirm in context; load if not already present): - Root `AGENTS.md` - `workflow/router.md` - `workflow/
