nx_attempt_loop.nx

nx_attempt_loop.nx -- the WARDEN's team-attempt loop over the assignment queue (X-Q-003 rung 1; spec ADDENDUM Q3 "team-attempt loop"). NOTE the basename nx_work_dispatcher that nx_assign_next's header reserved for Q3 was already taken 2026-06-05 by the governor-era policy lib (imported by nx_assignments_run/nx_team_console), so Q3 ships under the spec's own words instead -- the older lib is untouched. One call = one beat: route the Conductor's pick. EXEC-recipe rows are attempted hands-off (durable lane build+run under a conf deadline, hang-proof via nx_guarded_run) and judged ONLY by nx_reconcile's evidence flip -- never by the recipe's exit code (the fake-green class dies here). Uncovered rows are RAISED (TODO->NOVEL = the tutor batch, "a raised-hand row instead of a silent stall") and the best covered row is attempted in the same beat, so a raise never wastes a beat. ASSIGNRESULT rows append to assign_next.log (one marching-order + outcomes stream). Policy lives in nx_wd_core.nx; this is the thin real-paths main (the pulse runs it arg-free; the gate drives the core on scratch paths). exit 0 = healthy beat (attempt GREEN, raise, or idle) exit 1 = attempt RED (row flipped RED; queue-health escalates) exit 101 = queue missing license_tier: ORIGINAL
