# Pattern Validation

Every ratified pattern must satisfy seven constitutional invariants:

1. **Universal applicability** — no product or growth vocabulary
   (PosterityOS, HeadsUp, LOX, Atlas, "user", "customer",
   "engagement", "conversion", …).
2. **Implementation independence** — no UI, code, or technology
   vocabulary (interface, screen, button, database, API, React,
   browser, code, …).
3. **Constitution compatibility** — referenced volumes and doctrines
   stay within the ratified constitutional world.
4. **HSG compatibility** — every pattern names at least one ratified
   volume and doctrine.
5. **Human dignity protection** — no exploiting, manipulating,
   coercing, or deceiving language.
6. **Attention protection** — attention is never treated as a
   resource to capture or maximize.
7. **Continuity preservation** — the pattern is stated so
   understanding can be carried forward.

Reports are produced by `validatePattern()` and
`validatePatternLanguage()`; `patternLanguageIsValid()` is the
one-shot invariant.
