# Wiki Change Log

All modifications to the local `wiki/` directory are recorded here
in reverse chronological order (most recent first).

Each entry uses this format:

```markdown
## [YYYY-MM-DD HH:MM] - [ACTION TYPE]
- **File Affected:** `wiki/path/to/file.md`
- **Description:** Brief summary of what knowledge or structure changed.
- **Source:** Chat conversation, raw file, URL, or skill name.

```

Changes to pages under `wiki/decisions/` live in `wiki/decisions/log.md`
instead, per the Recursive Index & Log Convention.

## [2026-09-21 22:41] - UPDATE (schema 1.4 -> 1.5)
- **File Affected:** `wiki/index.md`
- **Description:** Bumped `kb_schema_version` to `"1.5"`, which adds the reserved body sections (`## Sources`, `## Crux`, `## Notes`), the `source_fingerprint`/`source_checked` frontmatter fields, and a completed edge vocabulary. Additive only — every 1.4 page remains valid.
- **Source:** Chat conversation (analysis of trailhq/Graft), branch `graft-ideas`.

## [2026-09-21 22:41] - RESTRUCTURE
- **File Affected:** `wiki/graph/index.md`
- **Description:** Replaced the prose edge list with a closed vocabulary table defining each verb by the question it answers, and added the missing `part_of` (written by `ckb-code-map` but previously undocumented) plus `produces`, `configures`, `validates`, `implements`. Added conventions on edge direction, evidence-only edges, and in-degree as a retrieval signal.
