nx_ale_aggregate.nx

nx_ale_aggregate.nx -- sovereign ALE AGGREGATE fold organ (rung ALE-R1c). ALE's HEADLINE measure: folds N per-task milli-scores (each a deterministic [0,1000] grade from nx_ale_grade) into ONE clamped mean on [0,1000] -- the single capability number on the leaderboard (frontier ~26% = ~260 milli). PURE function of one file: argv[1] = FIXTURE path (per-task lines "task|<id>|<milli>"; # / blanks ignored) argv[2] = scratch OUT path: the organ writes agg|<agg>\n # the single clamped headline mean task|<id>|<milli>\n x N # re-foldable per-task breakdown so the gate reads back the aggregate + breakdown WITHOUT hitting the 0..255 process-exit-code ceiling. FOLD (milli-units, 1000 == 1.0), data-driven, NO magic numbers: per-task milli is clamped to [0,1000] ON READ (defensive at the boundary, rule 12: a corrupt out-of-range per-task value can never inflate the aggregate) sum = sum over tasks of clamp(milli, 0, 1000) # data-driven, from the fixture N = count of "task|" lines in the fixture # the fixture owns the count mean = sum / N # integer division (floor) agg = clamp(mean, 0, 1000) # BOUNDED into [0,1] inclusive N == 0 -> agg 0 (degenerate empty task set; no divide-by-zero) Deterministic by construction: no clock, no rand -- only the fixture decides the agg. Landmines respected: nested ifs (no &&/||), flat exprs, <=6 args/func, no empty-string literal, strings via Write, openat_wr has no O_TRUNC (scratch is fresh per gate run). license_tier: ORIGINAL
