Neither file is committed: `artifacts/` is ignored by a `.gitignore` I didn't create, and I didn't force-add anything. The report stays untracked for the daemon to pick up, but the README won't be delivered through git. No independent reviewer has checked the report.\n\n**What the three approaches assume:**\n- **Fraud proofs (Optimism, Arbitrum BoLD):** one honest challenger is enough, but results wait out a challenge window of about 6.4–7 days. They need bonds and a dispute game. Both systems still keep a Security Council override. The known weakness is that nobody bothers to check when checking is expensive (the \"verifier's dilemma\").\n- **Quorum attestation (Chainlink OCR, TUF, Chrome's Certificate Transparency policy, transparency-log witnesses, Sigsum):** results are immediate, but a set threshold of signers must be honest. It breaks when signers aren't truly independent. In the Ronin bridge hack, one company controlled 4 of the 9 validators plus the use of a fifth, which was enough to meet the 5-of-9 threshold.\n- **Reproducible builds (Bitcoin Core's builder attestations, Debian, SLSA):** anyone can re-check a result, but that only detects problems. Something else has to act on a mismatch. It is also what makes the other two approaches meaningful.\n\n**Recommendation (my inference, not from a source):** keep the existing signed service and add one independently run co-verifier that re-runs the same check and co-signs the result, as transparency-log witnesses do.\n1. Make the verifier's output reproducible first, so two verifiers can agree exactly.\n2. Run the co-verifier in observe-only mode and log any disagreements.\n3. Require both signatures (2-of-2).\n4. Grow to more verifiers with a threshold (e.g. 2-of-3), with a rule that no operator holds more than one seat.\n\n**Main tradeoffs:**\n- At 2-of-2, either operator can stop verification by going offline.\n- Two operators can still collude.\n- If both run the same code, one bug gives two matching wrong answers.\n- Any non-deterministic step in the check causes false disagreements.\n- Co-signing doesn't stop the primary operator from choosing or withholding what gets verified.\n\n**What I couldn't confirm:**\n- I did not inspect your network's actual verifier, so the recommendation depends on its check being deterministic, which I don't know.\n- Three points rest on secondary sources: the OCR fault thresholds (the primary PDF couldn't be read), TrueBit's incentive mechanism (the PDF couldn't be fetched), and Ronin's postmortem wording (the page returned a 404). The report labels these.\n\nEvery claim is marked as fact, inference or uncertain, and open questions and sources are at the end.","treeHash":"4b825dc642cb6eb9a060e54bf8d69288fbee4904","usage":{"cachedInputTokens":508413,"inputTokens":34,"model":"claude-opus-5-5","outputTokens":15226,"runtime":"claude","turns":38,"wallClockMs":202855}}],"verification":[{"checks":[],"detail":"paths and tree verified; no suite was run for this kind of work","evaluation":"structural","profile":"none","status":"accepted","submissionHash":"31f58e659e58cfe4976654375a3a6e19eb48957640ca1c80556d7da5e80ab6e0","verifiedTreeHash":"4b825dc642cb6eb9a060e54bf8d69288fbee4904","verifierVersion":"0.1.0+1b3bcb5e"}]}
