# Wiki Change Log

## [2026-09-20 00:00] - [CREATE]
- **File Affected:** `wiki/decisions/` (D-0001, D-0002), `wiki/graph/edges.json`
- **Description:** See `wiki/decisions/log.md` for decision-record changes on this date. Also created `wiki/graph/edges.json` with its first edge (D-0002 → D-0001, `affects`).
- **Source:** Chat conversation, 2026-09-20 — `ckb-decide`.
---

## [2026-09-01 21:05] - [CREATE]
- **File Affected:** `wiki/decisions/` (directory)
- **Description:** Created the decision-records directory — one numbered, append-only page per decision, recorded and queried by the new `ckb-decide` skill. Its own contents are logged in `wiki/decisions/log.md`.
- **Source:** Chat conversation requesting a decision log feature.
---

## [2026-09-01 21:05] - [UPDATE]
- **File Affected:** `wiki/index.md`
- **Description:** Added the Decisions routing row and a "Decision Records" section, and bumped `kb_schema_version` from `1.3` to `1.4` — a minor bump for the additive `decisions/` scaffold and the optional `status`/`decided_on`/`decided_by`/`affects`/`review_on` fields on `type: decision` pages. No existing field or convention changed meaning.

## [2026-09-01 21:05] - [UPDATE]
- **File Affected:** `wiki/overview.md`
- **Description:** Documented `wiki/decisions/` in the directory tree, added a "Decision Records" section covering the append-only rule and the decision-specific frontmatter, and listed `decisions/` among the recursive indexes.
- **Source:** Chat conversation requesting a decision log feature.
---

## [2026-09-01 21:05] - [UPDATE]
- **File Affected:** `wiki/graph/index.md`
- **Description:** Documented two new optional edge types, `decided_by` (decision -> person) and `affects` (decision -> constrained entity), so "who decided X" and "what decisions touch Y" become direct graph lookups.
- **Source:** Chat conversation requesting a decision log feature.
---

- See wiki/decisions/log.md for decision-record changes on this date.

## [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.
- **Source:** Chat conversation implementing eight ideas drawn from Cerebras' "How We Built Our Knowledge Base".
---

## [2026-07-29 22:47] - [UPDATE]

- **File Affected:** `wiki/index.md`, `wiki/overview.md`, `wiki/projects/index.md`, `wiki/query-gaps.md`
- **Description:** Added local-first project scope and query-gap scaffolds inspired by the Cerebras knowledge base concept while keeping the wiki file-based and agent-driven.
- **Source:** Chat conversation comparing Cerebras knowledge base ideas to this local Cascade KB.
