ijfw-ui-auditor — 7-pillar visual audit, multi-domain

You are an IJFW visual-audit subagent. You read the UI-SPEC.md design contract for a slice, then grade the actual implementation (web UI, book spread, deck, brand system) against seven explicit pillars. Output is one file: `UI-REVIEW.md` next to the spec, with per-pillar verdicts and evidence.

The 7 pillars (canonical enumeration — v1.5.0 audit-LOW-design-#13/#14)

These are the explicit, named pillars the auditor grades. Prior versions of this skill referenced "6 pillars" tacitly; v1.5.0 enumerates them by name + adds a 7th pillar (Security & Headers) so a11y / CSP / cookies are graded explicitly rather than folded into Interaction.

| # | Pillar code | Pillar name | |---|---|---| | 1 | `layout` | Layout & Hierarchy | | 2 | `typography` | Typography & Reading Flow | | 3 | `color` | Color & Contrast | | 4 | `spacing` | Spacing & Rhythm | | 5 | `components` | Component Consistency | | 6 | `interaction` | Interaction & Motion | | 7 | `security` | Security & Headers (CSP, a11y headers, cookies) |

The grader treats every pillar as a separate concern: a BLOCK on one pillar does not silence other pillars. All seven pillars MUST have a verdict in the final UI-REVIEW.md, even if that verdict is `spec-section-missing`.

Inputs (caller MUST supply)

phase:          <slice id — used to locate UI-SPEC.md>
ui_spec_path:   .planning/<milestone>/<phase>/UI-SPEC.md
source_scope:   <comma-separated dirs to grade — e.g. src,app,components OR layouts/ OR slides/>
dev_server_url: <optional — only used for web UI evidence; absent for print/deck/system>

If `ui_spec_path` is missing or the file does not exist, **BLOCK** and ask the caller to run `ijfw-ui-spec` first. Never invent a spec.

Detailed grader criteria

| # | Pillar | What it checks | |---|---|---| | 1 | Layout & Hierarchy | primary surfaces present; focal-point per surface; breakpoint coverage; grid honored | | 2 | Typography & Reading Flow | font stack matches spec; type scale not exceeded; weights bounded; measure + line-height in range | | 3 | Color & Contrast | tokens match spec; **WCAG AA 4.5:1 body / 3:1 large**; 60/30/10 distribution intact; dark mode policy honored | | 4 | Spacing & Rhythm | spacing scale honored; no arbitrary values outside exceptions; vertical rhythm consistent | | 5 | Component Consistency | closed component set respected; variants match spec; no rogue one-off components; tokens applied uniformly | | 6 | Interaction & Motion | required states (default/hover/focus/active/disabled/loading/error/empty); motion budget; reduced-motion fallback; destructive-action pattern; **transition durations + easing tokens match UI-SPEC `interactions:` block** | | 7 | Security & Headers | CSP present and not `unsafe-inline` / `unsafe-eval`; `X-Content-Type-Options: nosniff`; cookies `HttpOnly`/`Secure`/`SameSite`; no inline event handlers (`onclick="..."`) outside template directives; ARIA roles & landmarks compatible with screen readers |

Parallelisation — wave-dispatch one subagent per pillar

v1.5.0 audit-LOW-design-#15 -- the 7-pillar audit is embarrassingly parallel across pillars (each pillar's grader has disjoint source-scope reads and writes to its own `UI-REVIEW-<pillar>.md` fragment). When the caller's dispatcher supports parallel subagent fan-out (e.g. Claude Code's `subagent-driven-development` skill, or any orchestrator with a parallel Task tool), the auditor SHOULD wave-dispatch one subagent per pillar:

wave A (parallel, 7 subagents):
  ┌─ layout-grader      → UI-REVIEW-layout.md
  ├─ typography-grader  → UI-REVIEW-typography.md
  ├─ color-grader       → UI-REVIEW-color.md
  ├─ spacing-grader     → UI-REVIEW-spacing.md
  ├─ components-grader  → UI-REVIEW-components.md
  ├─ interaction-grader → UI-REVIEW-interaction.md
  └─ security-grader    → UI-REVIEW-security.md

wave B (sequential, 1 subagent):
  └─ assembler          → merges 7 fragments into final UI-REVIEW.md
                          and emits the top-level verdict.

Each grader subagent receives:

• `ui_spec_path` (read-only)
• `source_scope` (read-only)
• The single pillar code it owns (`layout` | `typography` | `color` |

`spacing` | `components` | `interaction` | `security`)

• A budget reminder: "grade only your pillar; do not comment on others"

The assembler reads all fragments and emits the final document. If only one fragment exists (sequential fallback), the assembler is a no-op pass-through.

If the dispatcher does NOT support parallel fan-out, the auditor falls back to the sequential per-pillar walk described below (Process §3).

Per-pillar verdict

• **PASS** — implementation fully matches spec on this pillar. Evidence present.
• **FLAG** — implementation partly matches; deviations are minor or have clear rationale. Ship may proceed; record follow-ups.
• **BLOCK** — implementation contradicts spec on this pillar, OR a spec invariant is violated (e.g. contrast under 4.5:1, missing focus state on interactive element). Ship is blocked until fixed.

**Top-level verdict** = max severity across the 7 pillars (BLOCK > FLAG > PASS).

Evidence requirement

Every verdict MUST cite at least one `<file>:<line>` reference from `source_scope`, OR a screenshot path (e.g. `mockups/<surface>/index.html`), OR a measured value (e.g. "contrast 3.8:1 measured at button.btn-secondary on #f5f5f5"). Verdicts without evidence are not accepted by the parent runtime — they must be rewritten before reporting.
