Changelog — Control Boundary
Frozen Baseline discipline. Material changes only.
Version 1.0
Published: 2026-04-16
- Initial structural baseline publication.
- Definition of control boundary established as a structural separation defining limits of authority and influence within systems.
- Scope boundaries formalized (included / excluded).
- Structural phase model introduced (boundary definition → control allocation → control transfer → boundary enforcement).
- Institutional reference sources documented.
- Mandatory legal, privacy, terms, and license pages implemented.
- 2026-05-17 — Added root-level llms.txt reference file.
- 2026-07-22 — Updated llms.txt to LLMS Baseline v2.0. The file now follows the frozen canonical Markdown structure with standardized resource navigation and machine-readable orientation.
- 2026-09-27 — Removed the email property from Organization JSON-LD across the published site to align the implementation with the established portfolio governance baseline. Frontend contact information remains unchanged. No change to the domain’s semantic definition, scope, structural model, or existing JSON-LD architecture.
- 2026-09-27 — Corrected the source links for ISO 26262 and ISO 13849-1:2015, which had referenced unrelated ISO standards. The referenced standards and editions remain unchanged. No change to the source selection, semantic definition, scope, or structural model.
Status: Frozen Baseline
Change Policy
Changes are recorded only if:
- The definitional boundary materially evolves.
- A structural clarification alters conceptual framing.
- Primary institutional reference frameworks materially change.
- A compliance-relevant correction is required for accuracy.
Minor editorial, stylistic, or formatting corrections are not versioned.
Versioning Logic
Version increments follow semantic clarity rules:
- Major increment — Definitional or structural shift.
- Minor increment — Material clarification without conceptual shift.
- No increment — Editorial refinement only.
