feat(craft): state-coverage module + opt-ins on dashboard, mobile-app, kanban-board (#502)
* feat(craft): add state-coverage rules + opt-ins on dashboard, mobile-app, kanban-board

State coverage is the most reliable AI-design failure: agents ship only the
populated state. This adds craft/state-coverage.md (108 lines, matches the
existing craft format) covering the five required states (loading, empty,
error, populated, edge), three form-specific states, ARIA/focus rules, and
loading-duration thresholds.

Sources are public: WCAG 2.2, NN/g, Material Design 3, Apple HIG, Baymard.

Three skills with stateful UI opt in via od.craft.requires:
  - dashboard
  - mobile-app
  - kanban-board

Decks, ppt, image-poster and other static-output skills do not opt in.

Refs: see issue body for the broader proposal (state-coverage is module 1
of 5 behavioral craft modules).

* fix(craft): address review findings on state-coverage

Four P2 findings from #502 review addressed in one pass.

- Edge state Test matrix added under the five-states table (dashboard,
  mobile, form, search, detail-view scenarios with concrete thresholds).
- Server-driven empty pattern added as trailing note in the empty-state
  composition section.
- Retry discipline subsection added after error severity tiers
  (immediate first retry, exponential 2s/4s/8s backoff, 3-retry floor,
  Last-attempted timestamp).
- README enforcement-levels subsection added distinguishing auto-checked
  P0 rules from guidance; partial-stateful skill clarification added
  after the Files table.

No rewrites. ~30 lines added. File stays inside the 80-110-line craft
target.

* fix(craft): correct lint enforcement claim + remove duplicate threshold message

Two findings from @mrcfps review (Looper-generated against ee95b909).

- README: rewrote Enforcement-levels P0 description. Verified against
  apps/daemon/src/server.ts:1706-1727: /api/artifacts/save writes the
  file first, then calls lintArtifact, then returns findings in the
  response. Findings reach the UI (P0/P1 badges) and the agent (system
  reminder for self-correction). Persistence is not hard-blocked on P0.
  Original wording mischaracterized this as a generation gate.
- state-coverage: 30-60s duration-table bucket no longer duplicates the
  '15 s taking longer than expected' message from the loading row.
  Reworded to focus on cancel affordance and explicitly note the
  longer-than-expected notice already fired at 15 s.

Both findings non-blocking per Looper but genuine factual issues. Fixed
in one pass.

Craft references

Brand-agnostic craft knowledge. Each file is a small, dense rulebook on one dimension of professional UI craft (typography, color, motion, …). Skills opt into the references they need; the daemon injects only the requested ones into the system prompt above the active skill body.

Why a third axis next to skills/ and design-systems/

Axis Scope Example
skills/ Artifact shape saas-landing, dashboard, pricing-page
design-systems/ Brand visual language (the 9-section DESIGN.md) linear-app, apple, notion
craft/ Universal craft knowledge — true regardless of brand letter-spacing rules, accent-overuse caps, anti-AI-slop

DESIGN.md tells the agent which colors and fonts a brand uses. craft/ tells the agent the universal rules a competent designer applies on top — e.g. ALL CAPS always needs ≥0.06em tracking, regardless of the brand.

How a skill opts in

Add an od.craft.requires array to the skill's front-matter. Only the listed sections are injected, so a skill that needs only typography pays no token cost for color/motion content.

od:
  craft:
    requires: [typography, color, anti-ai-slop]

Allowed values match the file names in this directory minus the .md extension. Unknown values are silently ignored (forward-compatible).

Why silent fallback instead of fail-fast?

A skeptical reader will ask: "If a skill requests motion and we don't ship motion.md yet, shouldn't we warn the user?" We chose forward-compatibility over fail-fast: a skill authored today can list motion and start benefiting the moment we vendor craft/motion.md in a follow-up PR, with no skill edit needed. The cost of a missed reference is a missing paragraph in the system prompt, not a broken skill — so the loud failure mode is not worth the friction.

Enforcement levels

Craft files mix auto-checked rules and guidance.

  • Auto-checked. Rules wired into apps/daemon/src/lint-artifact.ts — currently the P0 list in anti-ai-slop.md (Tailwind-indigo accent, two-stop hero gradients, emoji-as-icons, etc.). The linter reports these as findings back to the UI (for P0/P1 badges) and to the agent (as a system reminder for self-correction). Artifact persistence is not currently hard-blocked on P0 hits.
  • Guidance. The rest. The agent reads the rules, reviewers apply them, the linter doesn't check them.

A purely behavioral craft file (state-coverage, animation-discipline) is guidance unless a specific rule is later promoted into lint-artifact.ts.

Files

File Section name When to require
typography.md typography Any skill that emits typed content (~all skills)
color.md color Any skill that emits styled output (~all skills)
anti-ai-slop.md anti-ai-slop Marketing pages, landing pages, decks
state-coverage.md state-coverage Any skill with stateful UI (dashboards, mobile apps, forms, list/table views)

Partial-stateful skills. A skill that's mostly static but contains an embedded form, data table, or query surface should opt in. State-coverage rules apply to the stateful component, not the whole page.

More sections (motion, icons, craft-details) will be added in follow-up PRs as we wire the linter side.
