nx_build_pipeline.nx

nx_build_pipeline.nx -- the WARDEN orchestrates the team building a capability end-to-end through the CLEAN RACI (operator: "keep building our teams capabilities" + the standing rule that each role owns its verb). One assignment flows: PM assigns -> BUILDER scaffolds -> [CORE] -> ENGINEER verifies -> on fail DOCTOR heals -> ENGINEER re-verifies -> COUNCIL admits -> LIBRARIAN registers. The Warden only ROUTES (it never tests or heals itself -- separation of duties via nx_build_raci). The [CORE] step is the one honest gap: if the assignment's core matches a known PATTERN the team authors it autonomously (bp_claude_touch=0); if it's NOVEL, the pipeline FLAGS needs-tutor (bp_claude_touch=1) -- the path to full autonomy is growing the pattern library so that flag goes to 0. We MEASURE the dependency, not hide it. Composes nx_build_raci (separation + decide) + nx_role_audit. LAWS: struct-free, integer-only. license_tier: ORIGINAL
