# Wiki Change Log

## [2026-07-30 08:40] - [UPDATE]
- **File Affected:** `wiki/index.md`
- **Description:** Bumped `kb_schema_version` from `1.2` to `1.3` — a minor bump for the additive `has_expertise_in`/`owns` graph edge types. No existing field or convention changed meaning.
- **Source:** Chat conversation implementing eight ideas drawn from Cerebras' "How We Built Our Knowledge Base".

## [2026-07-30 08:38] - [UPDATE]
- **File Affected:** `wiki/graph/index.md`
- **Description:** Documented two new optional edge types, `has_expertise_in` and `owns`, alongside the existing structural ones, so "who knows about X" / "who owns X" become direct graph lookups. Both are evidence-only — never inferred from meeting attendance or job title.
