Wiki

A wiki is an indexed folder tree of _index.md files. A node works with two:

• Project wiki ($WIKI_DIR) -- shared across nodes; per-branch, reaching others only through merges (use fractal radio for live coordination). Holds architecture, conventions, and patterns; contribute durable project-wide knowledge here.
• Memory ($MEMORY_DIR) -- this node's private knowledge base. See the memory skill for how to maintain it.

Todo lists follow the same split: a private working checklist lives in memory; a task list other nodes should see and track lives in the project wiki. Either way it is living state -- current open items, pruned as they complete -- never an append-only log.

Run wiki --help and wiki <command> --help for the CLI (init, update, lint, map, search, read). Always pass --path ($WIKI_DIR or $MEMORY_DIR) -- a bare command resolves the enclosing wiki by walking up, else {cwd}/wiki, which from the node's cwd need not be the project wiki ($WIKI_DIR) and is never memory, so an omitted --path silently targets the wrong wiki or errors. Run wiki update --path=<dir> after adding, moving, or deleting pages; wiki lint --path=<dir> validates structure.

Editing discipline

Name pages and folders in ascii snake_case (command_core, not command-core) -- both wikis enforce identifier-safe names (the project wiki's mirror the source modules they document), so wiki lint rejects hyphens and spaces. The rule allows ., so a non-markdown file keeps its extension (controls.json).
