## Structured Navigation (for AI agents)

This site publishes a KCP v0.6 manifest at https://wiki.totto.org/knowledge.yaml
containing 67 units with intent declarations, trigger keywords, and 83 relationships.

Fetch knowledge.yaml for targeted queries. Parse YAML → match query against each unit's
`triggers` (keyword list) and `intent` (natural language) → fetch the `path` of the best
match. Use `relationships` to navigate related content (types: enables, context, depends_on).

Example: "What is Synthesis?" → trigger `synthesis` → unit `synthesis-releases` → fetch notes/synthesis-releases.md

For broad overviews, https://wiki.totto.org/llms-full.txt covers all 87 posts and the full CV in one fetch.
