Trust Model

Five trust tiers

Presented as an ascending model. A record carries the tier its current handling supports. Each tier is a product capability the platform is designed to provide when configured — not an unconditional guarantee about every record.

  • Tier 1

    Preserved record

    The event is captured and preserved as a durable record.

  • Tier 2

    Cryptographic consistency

    The record is part of a structure whose internal consistency can be checked cryptographically.

  • Tier 3

    Signed content-bound proof

    The record is a signed proof bound to its specific content.

  • Tier 4

    Authoritative anchored proof

    The signed content-bound proof is anchored to an authoritative reference point.

  • Tier 5

    Locked-retention proof

    The proof is held under a locked-retention regime for its defined preservation window.

Fail-closed & authority

Proofs verify or withhold

ProvableCORE is fail-closed by design: when a proof cannot be properly constructed, signed, or preserved, the system withholds a positive result rather than issuing an unverified one. AI and automated systems act under human and institutional authority — ProvableCORE records that authority; it does not replace it.
