The protocol

A proof protocol, not a black box.

APLOMB does not pick the most frequent answer. It looks for what actually establishes it. Seven visible, traced steps, and an eighth that is a deliberate refusal.

  1. Decompose

    The answer is split into verifiable claims, one by one.

    List of claims

  2. Retrieve

    Each claim is checked live against official sources.

    Candidate sources

  3. Qualify

    Authority, recency, jurisdiction, independence, reproducibility of each source.

    Accepted or rejected sources

  4. Cross-check

    Several independent models are set against each other; an adversarial pass challenges the first.

    Agreements and divergences

  5. Arbitrate

    Deterministic rules decide: a repealed source proves nothing, a figure without a date proves nothing.

    Level of proof

  6. Answer or abstain

    If proof is insufficient, APLOMB abstains and says so. Abstention is a normal outcome.

    Verdict

  7. Seal the trace

    A signed, timestamped, third-party-verifiable certificate freezes the verification trace.

    Certificate

APLOMB certifies the integrity and traceability of the verification process, and documents the level of proof obtained. It does not certify absolute truth.
