5D guides
Build from the boundary outward.
Implementation guides for authority, failure, retries, and decision evidence. Each guide states what 5D supports and what your application still owns.
Canonical questions
One guide for each implementation problem.
These pages describe 5D-specific mechanisms. Broader analysis remains canonical on langoni.me.
