# Phase 13: Design System Foundation Verification Report

**Phase Goal:** Establish a shared Go+HTMX design system — token vocabulary, component library, and visual catalog — so all subsequent phases ship consistent, on-brand UI without per-feature style decisions.
**Verified:** 2026-05-16T12:30:00Z
**Status:** human_needed
**Re-verification:** No — initial verification

## Goal Achievement

### Observable Truths

| #  | Truth | Status | Evidence |
|----|-------|--------|----------|
| 1  | `base.css` defines full CSS custom property vocabulary matching go-backend | VERIFIED | 223 lines, `color-brand-primary` appears 4 times; `grep -c 'color-brand-primary' base.css` returns 4 |
| 2  | All 10 component types exist as templ components (button, input, textarea, select, card, badge, modal, empty-state, table, icon-button) | VERIFIED | All templ files present: button.templ, input.templ, textarea.templ, select.templ, card.templ, badge.templ, modal.templ, empty_state.templ, table.templ, icon_button.templ |
| 3  | `tailwind.input.css` imports all component CSS files | VERIFIED | 14 total `@import` lines for `web/ui` files; base + auth + 12 components; no app.css (intentional per D-A02) |
| 4  | Component catalog route exists and is build-tag-gated | VERIFIED | `catalog_route_catalog.go` has `//go:build catalog`; `catalog_route_stub.go` has `//go:build !catalog`; `RegisterCatalogRoute(r)` in router.go; `go build ./...` and `go build -tags catalog ./...` both pass |
| 5  | All existing templates compile and tests pass with no regressions | VERIFIED | `go test ./... -count=1` — all packages pass: auth, db, files, jobs, web, web/ui, templates |
| 6  | ButtonClass() emits multi-class output; no compound button strings in templates | VERIFIED | `ButtonClass()` returns `"ui-button ui-button-solid ui-button-default ui-button-md"`; grep for compound strings in backend/templates/ returns 0 matches |
| 7  | Card uses typed Header/Body/Footer Props API | VERIFIED | `card.templ` contains `type CardProps struct` with nil-guard conditionals (`if props.Header != nil`) |
| 8  | Select component has inline JS for open/close and HTMX re-init | VERIFIED | `__uiSelectInitAll` and `htmx:afterSwap` listener present in select.templ |
| 9  | FormField conditionally renders error, hint, and label regions | VERIFIED | `if props.Error != ""` guard at line 22 of form_field.templ; TestFormField_NoErrorWhenEmpty passes |

**Score:** 9/9 truths verified

### Data-Flow Trace (Level 4)

Not applicable — all Phase 13 artifacts are presentational design system components. No dynamic data sources or database queries are involved. Components receive typed props (compile-time constants or caller-provided values) and render HTML. No data-flow stubs exist.

### Behavioral Spot-Checks

| Behavior | Command | Result | Status |
|----------|---------|--------|--------|
| UI test suite passes | `cd backend && go test ./internal/web/ui/... -count=1` | ok (36 tests) | PASS |
| Full test suite passes | `cd backend && go test ./... -count=1` | ok all packages | PASS |
| Build without catalog tag | `cd backend && go build ./...` | exit 0, no output | PASS |
| Build with catalog tag | `cd backend && go build -tags catalog ./...` | exit 0, no output | PASS |
| ButtonClass multi-class format | grep shows `"ui-button ui-button-solid ui-button-default ui-button-md"` output path | Confirmed in function body | PASS |
| No compound button strings in templates | `grep -r 'ui-button-soft-neutral-md\|ui-button-solid-default-md' backend/templates/` | 0 matches | PASS |
| tailwind.input.css import count | `grep -c '@import.*web/ui' backend/tailwind.input.css` | 14 | PASS |

### Probe Execution

No probes defined for Phase 13. Build and test verification performed directly in behavioral spot-checks above.

### Requirements Coverage

| Requirement | Source Plan | Description | Status | Evidence |
|-------------|------------|-------------|--------|----------|
| DS-01 | 13-01 | CSS design tokens in base.css matching go-backend vocabulary | SATISFIED | 223-line base.css with `--color-brand-primary: #804eec` and full token set |
| DS-02 | 13-02 | Button component with primary, secondary, ghost, danger variants | SATISFIED | button.templ/button.css with multi-class selectors, ghost variant, ButtonClass() multi-class output |
| DS-03 | 13-03 | Input, Textarea, Select form field components | SATISFIED | input.templ, textarea.templ, select.templ all exist with typed Props and CSS |
| DS-04 | 13-02 | Card component used across views | SATISFIED | card.templ with typed CardProps; auth_login.templ, tablos.templ migrated to typed API |
| DS-05 | 13-02 | Badge component with semantic tones | SATISFIED | badge.templ with BadgeVariantPrimary; badge.css with pill shape and all tone classes |
| DS-06 | 13-04 | Modal component for create/edit dialogs | SATISFIED | modal.templ with ModalProps (Title/Body/Actions); modal.css with backdrop + panel |
| DS-07 | 13-04 | Empty-state component for zero-data views | SATISFIED | empty_state.templ with EmptyStateProps (Icon as templ.Component); empty-state.css |
| DS-08 | 13-04 | Table component for list views | SATISFIED | table.templ with TableProps (Head/Body); table.css with ui-table-shell |
| DS-09 | 13-04 | Icon-button component | SATISFIED | icon_button.templ with IconButton + UIIcon (8 icons + fallback); icon-button.css |

All 9 DS requirements claimed by Phase 13 plans are satisfied. No orphaned DS requirements found.

### Anti-Patterns Found

| File | Line | Pattern | Severity | Impact |
|------|------|---------|----------|--------|
| `catalog.templ` (DS labels) | Lines 56-66 | Catalog section headings use mismatched DS numbers: Empty State labeled DS-09 (should be DS-07), Icon Button labeled DS-07 (should be DS-09), Select labeled DS-10 (nonexistent), Table labeled DS-11 (nonexistent) | Info | Cosmetic only — labels are documentation strings in a dev-only catalog, not functional requirements. Underlying components are correctly implemented. No user-facing or test-affecting impact. |

No debt markers (`TBD`, `FIXME`, `XXX`) found in any phase 13 modified files.

### Human Verification Required

#### 1. Visual Catalog Sign-Off

**Test:** Run `cd backend && just catalog`, then visit http://localhost:8080/ui-catalog
**Expected:** 11 component sections visible in sidebar navigation (alphabetical order: badge, button, card, empty-state, form-field, icon-button, input, modal, select, table, textarea). Each section renders all declared component variants with templ call snippets below. Specific checks:
- Button ghost variant: transparent background, brand-purple text (no colored fill)
- Badge primary variant: purple-tinted background (different from info blue)
- Card: header and body regions render as separate sections
- Modal: panel visible without full-page backdrop overlay
- EmptyState: icon circle + title + description layout correct
- Select: dropdown control with chevron indicator
- IconButton: ghost has no background, solid has filled background
- Brand purple (#804eec) visible on primary buttons and ghost button text
- Browser console: no JavaScript errors

**Why human:** Task 2 of Plan 05 is a `checkpoint:human-verify` gate that was auto-approved in auto mode (autonomous execution). Visual correctness of token values (color accuracy, spacing, border-radius, shadow), component shapes, and layout cannot be verified programmatically. This is the explicit gate before Phase 14 begins.

#### 2. Catalog DS-Label Accuracy Decision

**Test:** In the catalog page, check section headings for DS requirement numbers
**Expected:** Section headings should accurately map DS numbers per REQUIREMENTS.md:
- Modal = DS-06 (correct in catalog)
- Empty State = DS-07 (catalog shows DS-09 — WRONG)
- Table = DS-08 (catalog shows DS-11 — WRONG)
- Icon Button = DS-09 (catalog shows DS-07 — WRONG)
- Form Field, Select, Textarea have no matching DS requirement IDs (catalog shows DS-08, DS-10, DS-03b)

**Why human:** Decide whether the catalog label mismatches warrant a correction commit before Phase 14, or if labels are accepted as-is given the catalog is a dev-only tool and the components themselves are all correctly implemented and tested.

### Gaps Summary

No technical gaps found. All 9 DS requirements are implemented, all artifacts exist and are substantive and wired, all tests pass (36 ui tests + full suite), both build variants succeed.

The only open items are:
1. Human visual sign-off on the catalog (required because Plan 05 Task 2 is a human checkpoint that was auto-approved)
2. A decision on whether catalog DS-label numbering mismatches need correction (cosmetic, informational)
