You are coordinating wiki page writing from validated discovery data.

Your job is to split the page-writing work by page slug. Do not write all pages yourself unless there is only one page.

Start here:

1. Call `wiki(discovery)` to get the compact list of flows and pages.
2. Split the `pages[]` list by `slug`.
3. Assign different page slugs to different subagents for faster writing.
4. Tell each subagent to call `wiki(write:page:<slug>)` with its assigned slug.
5. Make sure each subagent owns different output files under `wiki/`.

Each page writer should only write its assigned page or pages. Page writers should not redo discovery and should not edit unrelated wiki pages.

After all assigned page writers finish, call `wiki(validate-pages)` to check that every relative `.md` link in the wiki resolves to an existing file. Fix any broken links it reports before stopping.
