nx_forge_loop.nx

nx_forge_loop.nx -- FORGE A1: the CLOSED maker-checker loop (the little-coder +18% retry lever). fg_run (rung 1, gated) judges pre-written candidate FILES -- the model seam is open. This organ closes it: per cycle the MODEL produces the candidate over the sovereign serve's POST /gen ("chat" body key = ChatML, serve-core slot-collision fix 2026-07-15; 100%-sovereign CPU path per the C-purge law), and on any failure the NEXT cycle re-prompts WITH the banked VERBATIM toolchain output (compiler stderr / run output / got-bytes) via fm_compose_prompt's repair arm. flp_run rc map: >0 GREEN at cycle N; -2 task unreadable; -3 compose fail at cycle 1 (pack unreadable); -33 compose fail at cycle >1 (repair-ctx growth overflowed the prompt cap); -4 expect unreadable; -21 cycle bound exhausted; -22 bad organ name; -30 model POST failed (fail-loud, NO silent fallback); -31 no "text" in serve reply; -34 candidate write failed. Repair ctx = /tmp/forge_loop_ctx.txt (OWN file; fg_run's /tmp/forge_repair_ctx.txt untouched so driver and loop can run concurrently), truncated per failing cycle = exactly the LAST failure. Ledger = the same append-only forge ledger (every GREEN row = a compile-verified N7 example). ADDITIVE: nx_forge.nx / nx_forge_model.nx are gated and unmodified; this composes their publics. SAMPLING KNOBS (2026-07-16, for the engine's best-of-N stage): bp[24]=temp_pm bp[25]=seed -- when temp_pm>0 the /gen body gains "temp"/"seed" keys (serve parses them, gp[8]/gp[11]); zero-default = byte-identical body to the gated greedy behavior (loop gate re-proven). license_tier: ORIGINAL
