Purpose: Identify the small set of rules that all FPAT Lite commands share.
Intended reader: Agents and developers performing repository work.
Consult this when: Starting a session or resolving a workflow conflict.
Read in this order:
- Core rules — the 15 stable invariants.
- Safety and approval — mutation classification and approval rules.
- Engineering and validation — editing, testing, Git, and evidence rules.
The rules are intentionally short. Project-specific instructions may add constraints, but they may not silently weaken safety, evidence, or user-change preservation.
