Changelog

All notable changes to this handbook. Versioning follows SemVer; rule IDs are never renamed or reused.

1.0.1 - 2026-10-07

• Declare license: MIT in the skill frontmatter so gh skill publish validates cleanly.
• Pin the shared docs-lint workflow to a marketplace commit SHA.

1.0.0 - 2026-10-07

First release of data-standards, split out of Slight76/architecture-standards (v0.3.0, commit c1bda3d) as decided in ADR-0001.

Moved from architecture-standards@c1bda3d

Rule IDs, statements, and historic ADR references are unchanged. Wording was adjusted from "enterprise" to "team" and links were rewritten for the new repository layout; frontmatter was added.
