_attempt_loop_gate_authored.nx

_attempt_loop_gate_authored.nx -- gate for the Warden attempt loop (X-Q-003 rung 1 + the X-Q-006 SPEC build route). Drives wd_beat on a SCRATCH queue through the REAL sovereign lane, the REAL nx_reconcile elf and the REAL nx_auto_builder elf -- no mocks. Six beats: beat1: pick NOEXEC1 (w9, no recipe) -> RAISED to NOVEL, and the best covered row REDR1 (w8, recipe exits 7, no marker) is attempted in the SAME beat -> RED (raise never wastes a beat; fail-loud). beat2: LIAR1 (w7, recipe exits 0 but marker says RED) -> RED. THE anti-fake-green proof: exit codes never decide, evidence does. beat3: GREEN1 (w6, recipe appends its green marker) -> nx_reconcile flips it DONE on evidence -> GREEN. beat4: SPEC1 (w5, ||SPEC= build spec) -> auto-builder classifier-routes the shape, AUTHORS _pe_alspec1 + KAT, AUTOBUILD GREEN evidence, reconcile flips DONE: a queue row BUILT a new module hands-off. beat5: BADSPEC1 (w4, malformed spec) -> auto-builder REFUSES (exit 2), marker never green -> RED (bad specs die loud). beat6: nothing runnable -> IDLE row. Staleness killer: seed verdict=STALE lines for the green/liar anchors so a previous run's marker lines can never pre-flip a row (last-line-wins). Plus conf KATs (parse + default-on-absent). Markers: ALG-* checks; final ALGATE row -> knowledge/status/attempt_loop.log license_tier: ORIGINAL
