Fact Tags, Policy Tags, Evaluation Tags, and Process Tags preserve different types of Evidence and are also subject to different Authorities to Change. Separating them makes it possible to record observed Facts, Applicable Governance, Evaluation Methods, and Actual System Processing without conflating them, while preserving the Source and change conditions associated with each.

A Fact Tag records Facts observed or declared in advance based on Reality or External Evidence. The AI System has no Authority to retrospectively rewrite a recorded Fact to conform to an Evaluation result or other subsequent outcome. Facts are Externally Grounded and preserved within the System as historical Evidence. Where the real-world state changes, the new state is recorded as a new Fact while maintaining its Temporal Relationship with the previous Fact.

A Policy Tag records Policy established through Institutional or Organizational Governance. Policy may change, but the Authority to modify it is limited to Authorized Governance. Changes are managed as new Versions, while the Policy State applicable to past Decisions is preserved. A Policy Tag therefore represents Governance-defined and Version-controlled Evidence.

An Evaluation Tag records how a Fact was evaluated under Applicable Policy. Criteria, Thresholds, Sensitivity, Weight, Criticality, and related parameters may be configured by the Organization within the boundaries of and in Alignment with Applicable Policy. Evaluation is therefore Governance-constrained and Organizationally Configurable, enabling Evaluation to reflect Risk, Organization, Domain, and Use Context without modifying Policy itself.

A Process Tag records the Processing that actually occurred within the System and how that Processing was connected to Decision and Execution. It represents System-generated and Process-bound Evidence. Actual Processing cannot be retrospectively modified to conform to an Expected Workflow or preferred Outcome. Where Actual Processing differs from the Expected Process, the Deviation itself is preserved as Evidence.

Separating these four types of Records makes it possible to preserve:

Fact = What Is / What OccurredPolicy = What GovernsEvaluation = How It Is EvaluatedProcess = What the System Actually Did

as distinct forms of Evidence. Importantly, each also differs in who generates it, who may modify it, and what must not be modified.

This separation of Evidence and Authority enables subsequent Verification, Vigilance, and Audit / Assurance to reconstruct what constituted the Fact, which Rule applied, under which Configuration the Evaluation was performed, and what Processing the System actually carried out. Governance Records therefore become more than a collection of Logs. They form a Verifiable Evidence Structure that preserves the boundaries between Source, Authority, Evaluation, and Actual Processing.
