nx_regalloc_absorb_governed_test.nx

nx_regalloc_absorb_governed_test.nx -- the LOOP governs absorbing the allocator into codegen. Absorption is the risky step (the prior g1 attempt miscompiled), so it goes through the crew council (3->2->1) with the REAL gates as the Engineer's evidence: ENGINEER = the allocator is sound (ra_validate) AND execution-equivalent to the reference (ri_interp_ref == ri_interp_alloc) AND fits (0 spills). GENEALOGIST = novel (a new codegen path, not a duplicate). WARDEN = additive-safe (a NEW path; the known-good compiler is untouched). Only then does the Conductor ACT (absorb). A MISCOMPILING allocator (Engineer evidence fails) must be DENIED/ESCALATED -- governance blocks the g1 regression. Known answer: proven allocator -> council ACT (absorb); miscompiling allocator -> council NOT ACT (blocked). exit 0.
