Challenge details & success criteria

Prove that a fresh encrypted Solver artifact can move from independent Guardian evaluation through Agora's native Safe settlement path without per-bounty operator intervention after submission. This is the first of two disposable Base Sepolia acceptance proofs for issue #210. It shares the live Guardian Safe with proof C so deterministic candidate ordering and nonce serialization can be observed.

Acceptance criteria

  • proof_report.md exists and is valid UTF-8 Markdown.
  • It contains the exact marker agora-unattended-settlement-e2e-b-20260802.
  • It states result: pass on its own line.
  • It identifies the Solver as 0xf465b2e58d06e35353b861df7a30c8ea8adf79bd.
