- AGENTS.md: add factory principles and factory-integration-decisions to
on-demand content index so they are discoverable for skill design work
- write-skill: insert conflict-check step (step 3) — sub-agent reads
constitution and factory principles after grill, before any writing;
hard gate with explicit self-check item; renumber steps 3–8 → 4–9
- META.md: bump to v1.4
Closes the gap identified in PRD chunk-3-skills-library §sub-agent-usage:
conflict checking against constitution and factory principles was specified
but never wired into the write-skill process.
