nx_browser_arc_pipeline.nx

nx_browser_arc_pipeline.nx -- the WARDEN routes the BROWSER arc's open rungs (B1-B5, pm_plan arc=BROWSER) through the team's CLEAN RACI build pipeline. Evidence-driven: a rung's stage is DERIVED from the Engineer's durable gate log (knowledge/status/ browser_gate.log), never asserted -- a rung is ADMITTED only when its named gate row PASSES in the latest run; a FAILING row routes to the Doctor; an ABSENT row routes through bp_run, which flags NEEDS_TUTOR honestly when the core is novel (not yet in the Builder's pattern library) or SCAFFOLD-READY when the team can author it alone. The arc's autonomy permil (bp_autonomy_permil) measures how much of the browser the team can build hands-off -- driven up by adding pattern emitters, never by hiding the Claude dependency. Composes nx_build_pipeline (Warden) + nx_build_raci (RACI). LAWS: struct-free, integer-only, no shell. license_tier: ORIGINAL
