- Add sub-file constraint: content-type split rule (explains vs. directs),
three spec-defined optional directories (scripts/, references/, assets/),
one-level-deep rule, and wiring syntax requirement
- Update output format section to list optional sub-files as a third output
- Add self-check item for sub-file placement and wiring
- Update SKILL-TEMPLATE.md constraints and output format examples to match
- Bump META.md to v1.3
- Add two LESSONS.md entries: research agents presenting synthesis as spec
fact; META-TEMPLATE fix deferred with explicit do-not-apply note
