nx_autofix_localfix.nx

nx_autofix_localfix.nx -- THE LOCAL MAKER TAKES STAGE 4 (2026-07-16). The proven autofix loop (nx_autofix_gate, 6/6) has ONE Claude-authored piece left: the corrected line in stage [4 FIX]. This organ runs the SAME episode -- identify -> flag -> backup -> fix -> verify -> revert -- but the fix CONTENT is GENERATED BY THE LOCAL 1.5B no-float model (i8 light init, greedy). The independent grader (fresh compile+run, CGR=<pass>) remains the ONLY judge; a model echo or a broken line simply fails [5 VERIFY] and the episode records an honest MAKER-MISS (curriculum), never a fake green. HONEST SCOPE: bug LOCALIZATION is not attempted here -- the buggy line is the known seeded one (same as the gate); what goes local in this rung is the fix GENERATION. Prompting is few-shot (two worked examples of one-line function repairs); the max2 correction itself is the model's own completion. On MAKER-GREEN it appends `CGB ts=<ts> generator=15b-autofix-localfix tasks=1 localpass=1` to the codegen bench ledger -- the autograde target `local-codegen-green` (ge 1) then grades MET from a real machine-verified artifact. Green-only: a miss writes the episode row but never a localpass row. The loop itself must stay sound either way: backup before mutation, revert proven exact at the end. exit: 0 = loop sound (maker green OR honest miss) | 1 = loop unsound (backup/revert/harness failure) license_tier: ORIGINAL
