description	Umbrella catalog of all domain-spec DDD pattern references. Each pattern lives in a sibling folder of this file — `<pattern-name>/` containing `index.md` (the pattern doc) plus optional `template.md`/`examples.md` companions. Load to resolve pattern names to their reference docs by path instead of per-pattern skill invocations.

Domain-spec pattern catalog (umbrella)

This skill is a path-resolution anchor: it registers one catalog entry for all domain-spec pattern references. The pattern docs themselves are supporting files in folders next to this SKILL.md and are never auto-loaded — consumers Read them on demand.

Resolution rule

Every pattern named <pattern-name> resolves to the folder <pattern-name>/ sibling to this file:

• the pattern document is always <pattern-name>/index.md;
• companions, when present, sit in the same folder (template.md — the Jinja2-style code template the implementers render; examples.md — worked examples). Relative links inside index.md (e.g. [template.md](template.md)) resolve within that folder.

A pattern name that has no matching folder is an error — report it loudly; never skip it silently.
