BUILD FOR YOUR WORLD INDIE DEVELOPER TRACK

The document changed.
The decision should too.

When an invoice and a packing list disagree, guesswork costs time. TrueLanded verifies the evidence, prioritizes the missing proof and shows what changes when new documents arrive.

INTERACTIVE EVIDENCE REVIEW

One case. Three revisions.
See what the evidence changes.

VERIFYING SOURCE INTEGRITY…
Verification boundary: This demo uses a local simulated response in the Muse Spark 1.3 response format. The project owner separately completed a real Meta API request; that private receipt is not embedded here. Source hashes are locally computed, not supplier or Meta signatures.

EVIDENCE SPOTLIGHT

What does the source actually say?

SOURCE BOUND

Every model candidate must match an exact line in the fictional document. If it doesn't, TrueLanded refuses the result.

FICTIONAL TRADE DOCUMENT

    NEXT BEST PROOF

    What should we request next?

    Prioritized by deterministic evidence-planning rules—not by an unverified customs conclusion.

    HIGHEST-PRIORITY PROOFVERIFYING…Recommendation only. No request is sent.

    COUNTERFACTUAL CASCADE

    What changed with this revision?

    NEW UNCERTAINTY
    CONDITIONALLY RECONCILED

    ◉ Human review remains mandatory. Source issuer is not authenticated.

    TRY A NEW HYPOTHESIS · NO MODEL API CALL

    What if the invoice numbers changed?

    Change the fictional invoice quantity or total. The browser recalculates which contradictions remain, which proof is needed next and what changed. This does not modify any original source.

    Use a dot and exactly two decimals, e.g. 221.76.
    Verifying fictional source before calculation…
    TRANSPARENCY

    The model's role is candidate text extraction. The source match, prioritization and obligation changes come from TrueLanded's deterministic code.

    NO UNVERIFIED DATA DISPLAYED

    CHALLENGE THE RULES

    What if the sources disagree?

    Replay 30 fabricated attacks against typed documentary evidence: incompatible units, conflicting inspection counts, tampered source bindings and forged approvals. Results are reproduced by the included Python engine.

    MODEL PROVENANCE · NO CLAIMS OF PROVIDER SIGNATURE

    What Meta did. What TrueLanded calculated.

    These are separate technical roles. The current browser is an offline synthetic demonstration, not a new API request.

    META MUSE SPARK 1.3

    Candidate extraction

    In a separate, owner-recorded authorized Model API experiment, a synthetic three-document request returned HTTP 200. TrueLanded locally matched 18 of 18 candidate source literals. This historical result is not a provider-signed certificate and its private raw response is not distributed.

    Traceable reasoning

    Source matching, invariant checks, documentary obligation tracking, hypothetical changes and next-proof prioritization are computed by transparent rules. The what-if below uses integer-cent arithmetic and never calls a language model.

    REPRODUCIBLE JUDGE KIT

    Adversarial acceptance

    Python and Node tests verify synthetic cases, check source-index integrity and reject tampering. The package includes no credentials or customer documents and never files a customs entry. Source SHA-256 does not prove issuer authenticity.

    Independent clean-extract checks

    WHY THIS IS DIFFERENT

    Trust isn't a claim.
    It's a test you can rerun.

    01 / EXTRACT

    Model proposes

    Meta Muse Spark 1.3 supplies candidate literal fields in the verified API path. This website shows an offline test double—not a live request.

    02 / VERIFY

    Sources decide

    Exact source text, line anchors and SHA-256 checks fail closed if claims do not match the fictional documents.

    03 / PLAN

    Human retains control

    Ranked documentary requirements and hypothetical resolution changes assist review. No automatic filing or legal authorization.

    PROTOTYPE · OCTOBER 2026

    Evidence first.
    Action when justified.

    TrueLanded explores a practical future for global trade compliance: one where every recommended next step can be traced back to a document and challenged by a person.
