# Product Standards

> Canonical, living standards that govern all new and modified Filament UI surfaces.
> Specs reference these standards; they do not redefine them.
> Guard tests enforce critical constraints automatically.

## How Standards Are Enforced

1. **Constitution** — Principles in `.specify/memory/constitution.md` govern why we build this way.
2. **Standards** (this directory) — Concrete rules for how every surface must behave.
3. **Guard tests** — Automated Pest tests that fail CI when critical standards are violated.
4. **PR review** — The [review checklist](list-surface-review-checklist.md) is checked for every spec or PR that touches a list surface.

## When to Update Standards

- When a spec introduces a new surface type or pattern not yet covered.
- When a standard proves too rigid or too loose after real usage.
- When Filament version changes invalidate or enable new native features.

Update the standard first, then adjust implementation to match.
