Put Wiki Page

Create or update a page in the knowledge base.

The supplied body replaces the page content entirely. A user_edited_at timestamp is automatically added to the page's YAML front matter so the knowledge-base maintenance agent treats user-authored sections as append-only on its next pass.

page_path must end in .md and must sit at the repo root or under entities/, concepts/, or sources/. The seeded root pages (overview.md, DESIGN.md, VOICE.md) are writable like any other page; only deleting them is restricted. The schema is managed through PUT /api/v1/wikis/{wiki_id}/schema, so CLAUDE.md is rejected here. Paths that would escape the repo (.., hidden segments) are rejected with 404.

A knowledge base that has never been accessed is provisioned by the first write, so a headless workspace can seed its context through this endpoint alone.
