Enterprise Temporal History

Record effective timelines, preserve earlier recorded views and bind schemas and domain states without rewriting history.

4 bundles · 8 layers · 22 findings · 22 questions

Independent audit still pending

Grok completed independent research, but the separate frozen implementation audit is NOT REVIEWED: browser navigation/focus failed before prompt submission. Recovery is queued against the exact published release; this contour remains unfinished.
Host integrations, domain transitions, retention/erasure, calendar adapters, production capacity and existing-Dimension migration remain outside the reference.

Use in a Company Dimension

Start with one fact scope, a pinned domain value and its schema, then append complete effective-time snapshots. Query by effective date and recorded cutoff; later corrections preserve earlier recorded views. The package includes three synthetic examples, a closed schema, a reference validator and native installation checks.

Research assurance: reviewable-draft. This is a bounded original companion. A trusted host owns authentication, latest history, receipt clock and durable conflict handling. This companion does not establish source truth, domain transition legality or payload-schema conformance. Adoption limits.

Research and validation

Claude and Grok completed independent research. Claude completed three frozen static implementation audits after remediation. Grok’s separate implementation audit is unavailable and pending browser recovery; no Grok code-acceptance verdict is claimed. Executed tests and native checks are recorded separately.

Catalogue identity: vr.profile.enterprise-temporal-history. EM-XCT-04 remains a broader, partially covered research contour. Parent models are semantic references; no subtype or whole-parent conformance is asserted.
