- SKILL.md: confirm type/pattern/size/cuts with the user before rendering;
checklist hooks for the checkpoint and the packaged self-check
- scripts/verify-docs-sync.py: CI now fails when the frontmatter description
loses a type's lexical hook, the gallery can't reach a shipped example, or
the README tree names a missing file
- skills/diagram-design/scripts/self_check.py: distilled output checker that
ships with the skill so installed agents can verify their own diagrams;
adversarial suite in scripts/test-self-check.py
- assets/index.html: six new tabs (OAuth sequence + five single-variant
examples with a data-single variant lock) so every shipped example is
browsable
- docs/adr/0001-0004: settled policies recorded (pinned controller, taxonomy
freeze, reveal-only autoplay, byte cap + trigger-rich description)
- README: It's-working-if section, new gates documented; CONTRIBUTING: gate
table, ADR guidance, type-addition invariants; CI: two new steps
Add CONTRIBUTING.md covering all validation gates and contribution
workflows, CODE_OF_CONDUCT.md (Contributor Covenant 2.1), GitHub issue
templates (bug/feature), and a pull request template; add a Contributing
section to the README.
