nx_adversary_suite.nx

nx_adversary_suite.nx -- the ADVERSARY role's organ (verb: ATTACK -- author the hostile suite). v2 (race-6 rung): the ASSIGNMENT IS A GRAMMAR FILE -- a new race needs a new spec file and ZERO organ recompile (rule 11 carried to its end). The organ reads a container grammar: name <assignment-name> seed <n> deterministic LCG seed (reproducible, never wall-clock) hdr magic4 <packedBE4cc> header field: 4 magic bytes that must match hdr size4 <le> <bias> header field: u32 written as total-bias (RIFF size law) hdr skip <n> header field: n opaque bytes shape <type_w> <len_w> <type_first> <len_le> <pad2> <trail_w> the chunk wire shape count <label> census count key scalar <label> <off> <w> <le> raw header-scalar key (want = read-back from construction) watch <label> <packedtag> one find key per watched chunk type chunk <packedtag> <len> assignment table row (the construction) lane <name> <elfpath> referee lanes, copied verbatim CONSTRUCTS the well-formed image from the table (wants construction-known = the oracle), then applies the fixed perturbation TAXONOMY (the role's knowledge, assignment-independent): WELLFORMED / ZEROLEN (JUNK chunk first, every offset shifts) / TRUNC (cut mid-first-body, scalar zone kept) / GARBAGE (magic destroyed) / OVERLEN (last length inflated past EOF). Writes /tmp/rs_*.bin cases + /tmp/race_manifest.txt + /tmp/rs_manifest_tampered.txt + durable knowledge/status/adversary_suite.log. Usage: nx_adversary_suite [specpath] (default knowledge/specs/race_riff.suite). LAWS: struct-free, integer-only, FLAT ifs (4-deep nested-if miscompile landmine: per-line parser helper resets depth), no &&/||, <=6 args per func. license_tier: ORIGINAL
