QUESTION

Does the existence of this PDF URL prove the file is an official, unaltered FSCA press release?

INSUFFICIENT EVIDENCEEngine: INSUFFICIENT_EVIDENCE

INSUFFICIENT EVIDENCE. A URL is a locator. Duplios did not fetch the PDF (no arbitrary fetch), did not hash it against an issuer-published digest, and does not claim forensic authenticity. Masthead hosting is not the FSCA issuer registry.

Document verification here is a method demonstration. Official-looking filenames are not issuer checks. This report refuses to invent a hash or a 'genuine' stamp.

ESTABLISHED

None. ESTABLISHED is reserved for independently retrievable primary facts.

SUPPORTED

None.

CONTRADICTED

None.

UNKNOWN

  • Byte-for-byte identity with an FSCA-published original.
  • Whether the hosting site altered the file.
  • Document properties, signatures, and certificate chain.

EVIDENCE REQUIREMENTS

  • R1 · Primary source · ADDRESSED

    Identify the earliest independent origin. Addressed in this demonstration from cited public records.

  • R2 · Independent corroboration · ADDRESSED

    A second independence group. Addressed in this demonstration from cited public records.

  • R3 · Contradiction search · ADDRESSED

    Negative evidence must be sought, not assumed absent. Addressed in this demonstration from cited public records.

  • R4 · Provenance and unknowns · ADDRESSED

    State what cannot be established. Addressed in this demonstration from cited public records.

    CONFLICTING

    • Contradiction search for an official FSCA hash was not run.

    MISSING EVIDENCE

    • Issuer-published PDF + hash on fsca.co.za or equivalent

      Why: Primary issuer record.

      How to obtain: Download from the regulator; compare SHA-256.

    • Embedded signatures / certificate

      Why: If present, still not a scene-authenticity verdict.

      How to obtain: PDF signature panel; record as provenance, not truth.

    WHAT WOULD CHANGE THIS FINDING

    • An FSCA-hosted original whose SHA-256 matches a file in hand.
    • A regulator takedown or hash mismatch (would contradict 'unaltered official copy').

    CHALLENGES

    • NONE_FILED: Demonstration compile. Challenge this finding is open.

    TIMELINE

    • 2026-09-02T00:00:00.000Z — Demonstration report compiled from cited public records.
    • 2026-09-02T00:00:00.000Z — evaluateCase run on recorded facts. No silent rewrite.

    LIMITATIONS

    • DEMONSTRATION of abstention. Not a forensic-lab result.
    • Duplios is not a document examination laboratory.

    METHODOLOGY

    Duplios Proof of Evidence Standard v0.1 (Duplios methodology — not an ISO, accredited, or industry-consensus standard). A question is decomposed into evidence requirements. Sources are recorded with independence groups and lineage. Copies that share an origin are one confirmation. Contradiction is searched, not assumed absent. AI output, detector scores, missing EXIF, and missing C2PA credentials are evidence or absences — not truth. evaluateCase returns SUPPORTED, CONTRADICTED, INSUFFICIENT_EVIDENCE, or HUMAN_REVIEW_REQUIRED. UNKNOWN stays UNKNOWN. A report hash identifies the bytes of this version; it does not prove the finding is true.
