nx_ale_grade.nx

nx_ale_grade.nx -- sovereign ALE DETERMINISTIC grader-runner core (rung ALE-R1a). THE scoring engine the whole ALE-R1 harness routes through: the smallest load-bearing slice (deterministic, code-graded, [0,1], no leakage). PURE function of two files: argv[1] = REFERENCE path (list of grading-unit lines "unit|<name>|<value>") argv[2] = ARTIFACT path (the agent-produced deliverable, same line grammar) argv[3] = scratch OUT path (optional): the milli-score is written here as decimal text + newline, so the gate reads back a value in 0..1000 WITHOUT hitting the 0..255 process-exit-code ceiling. The score also goes to stdout. SCORE (milli-units, 1000 == 1.0), data-driven, NO magic numbers: total = number of "unit|" grading-unit lines in the REFERENCE (the rubric owns it) matched= number of reference grading-unit lines that appear VERBATIM (name+value) as a complete line in the ARTIFACT raw = (matched * 1000) / total # per-unit weight = 1000/total, DERIVED score = clamp(raw, 0, 1000) # BOUNDED into [0,1] inclusive total == 0 -> score 0 (degenerate empty reference: nothing to credit) Deterministic by construction: no clock, no rand -- only the two files decide the score. No-leakage: the grader reads argv[1] (reference) ONLY; the score is independent of when/ where the reference existed during the (separate) agent phase. Landmines respected: nested ifs (no &&/||), flat exprs, <=6 args/func, no empty-string literal, strings via Write, openat_wr has no O_TRUNC (scratch file is fresh per gate run). license_tier: ORIGINAL
