Phase 2 — UI Design Contract

Visual and interaction contract for Phase 2: Users & Authentication. Generated by gsd-ui-researcher, verified by gsd-ui-checker.

---

Design System

Property	Value
Tool	none — raw Tailwind CSS v3
Preset	not applicable
Component library	none
Icon library	Inline SVG heroicons (stroke, no fill) — matches existing AppSidebar and DocumentCard patterns
Font	System font stack (Tailwind default: ui-sans-serif, system-ui, sans-serif)

Source: Detected from frontend/package.json (no icon library installed), frontend/tailwind.config.js (empty theme.extend), and existing component audit.

---

Spacing Scale

Declared values (multiples of 4 only):

Token	Value	Usage
xs	4px	Icon-to-label gaps, badge internal padding, inline list gaps
sm	8px	Input icon padding, compact inline spacing
md	16px	Default field padding, card internal padding, form row gap
lg	24px	Section vertical gap, card-to-card gap
xl	32px	Form block top margin, admin table row height padding
2xl	48px	Auth page vertical centering padding
3xl	64px	Auth card max-height clearance from viewport edge

Exceptions:

• Touch targets (buttons, checkboxes, radio): minimum 44px height — enforced via min-h-[44px] on all interactive controls
• TOTP code input cells: 48px wide × 56px tall per digit cell (6 cells)
• Backup code grid cells: 8px horizontal padding, 12px vertical padding (between xs and sm)

---

Typography

Role	Size	Weight	Line Height	Tailwind Class
Body	14px	400 (regular)	1.5	text-sm
Label	14px	500 (medium)	1.4	text-sm font-medium
Heading	20px	600 (semibold)	1.3	text-xl font-semibold
Display	24px	700 (bold)	1.2	text-2xl font-bold

Source: Extracted from HomeView.vue (text-2xl font-bold page heading, text-sm body, text-lg font-semibold section headings) and DocumentCard.vue (font-medium text-sm). Heading reduced from text-lg to text-xl for auth page section hierarchy.

Font weight scale: exactly 2 weights in components (regular 400 + semibold/bold 600/700). Labels use 500 (medium) as the only addition for form ergonomics.

---

Color

Role	Value	Tailwind Token	Usage
Dominant (60%)	#f9fafb	bg-gray-50	Page background — all views
Secondary (30%)	#ffffff	bg-white	Auth cards, form panels, admin table rows, sidebar
Accent (10%)	#4f46e5	indigo-600 / indigo-700	Reserved for: primary CTA buttons only, active nav link text, brand logo text
Accent subtle	#eef2ff	indigo-50	Active nav link background, icon container backgrounds
Destructive	#dc2626	red-600	Deactivate user action, sign-out-all confirmation button, field validation errors
Warning	#d97706	amber-600	Password strength: weak/medium indicator only
Success	#16a34a	green-600	Password strength: strong indicator, TOTP enrollment success
Neutral border	#e5e7eb	gray-200	Card borders, input default border, table dividers
Muted text	#9ca3af	gray-400	Helper text, placeholder text, secondary metadata

Source: style.css (body bg-gray-50 text-gray-900), AppSidebar.vue (indigo-600 brand, indigo-50 active bg, indigo-700 active text), DocumentCard.vue (gray-200 border, hover:indigo-300). Destructive and warning added for auth-specific needs.

Accent reserved for: primary CTA buttons, active sidebar nav link text, DocuVault brand/logo text. Accent is NOT used on: input focus rings (use ring-indigo-500 only), links within prose, or secondary actions.

Input focus ring: focus:ring-2 focus:ring-indigo-500 focus:border-indigo-500 focus:outline-none

---

Form Field States

All text inputs (<input type="text|email|password">) follow this contract:

State	Border	Background	Ring	Text
Default	border-gray-300	bg-white	none	text-gray-900
Focused	border-indigo-500	bg-white	ring-2 ring-indigo-500	text-gray-900
Error	border-red-500	bg-white	ring-2 ring-red-500	text-gray-900
Disabled	border-gray-200	bg-gray-50	none	text-gray-400
Read-only	border-gray-200	bg-gray-50	none	text-gray-700

Base classes (all states share): block w-full rounded-lg px-3 py-2.5 text-sm transition-colors

Error messages appear inline, directly below the field, never as a toast. Class: mt-1 text-xs text-red-600. Maximum 1 error line per field.

---

Password Strength Indicator

Displayed below the password input on Register and Password Reset (new password) screens only.

Visual contract:

• 4-segment horizontal bar, full width of the input
• Each segment: 4px tall, rounded, gap-1 between segments
• Segments light up left-to-right based on score

Score	Segments lit	Bar color	Label
0 (empty)	0	—	hidden
1 (too short / fails rules)	1	bg-red-500	"Too weak"
2 (fails 2+ rules)	2	bg-amber-500	"Weak"
3 (fails 1 rule)	3	bg-amber-400	"Fair"
4 (all rules pass)	4	bg-green-500	"Strong"

Rules checked client-side (≥12 chars, uppercase, lowercase, digit, special char — matches AUTH-01):

• Label: text-xs font-medium at same color as the bar, right-aligned
• Unlit segments: bg-gray-200
• Layout: mt-2 space-y-1

HaveIBeenPwned breach check runs on blur (not on every keystroke). If the password is pwned, an inline error appears below the strength bar: "This password has appeared in a data breach. Choose a different password." — same text-xs text-red-600 style. The strength bar is NOT cleared; both messages coexist.

---

TOTP Enrollment Flow

Step 1 — QR Code Display

• QR code: 200px × 200px centered in a white card with border border-gray-200 rounded-xl p-6
• Manual secret: font-mono text-sm text-gray-700 bg-gray-50 px-3 py-2 rounded-md border border-gray-200 break-all
• Copy secret button: icon-only (clipboard SVG, w-4 h-4), text-gray-400 hover:text-gray-600, positioned inline right of the secret block
• Instruction copy: "Open your authenticator app and scan this QR code, or enter the key manually."

Step 2 — Code Verification

• Single 6-digit code input: rendered as one <input type="text" inputmode="numeric" maxlength="6"> field, NOT 6 separate cells
• Width: w-36 (144px), centered
• Error state on wrong code: field switches to error state + inline message "Incorrect code. Try again." — generic, no hint about time window
• On success: green checkmark icon (w-5 h-5 text-green-600) + "Authenticator connected." transition before proceeding to backup codes

Step 3 — Backup Codes Display

Layout: 2-column grid of codes (grid grid-cols-2 gap-2)

Each code cell:

• font-mono text-sm text-gray-800
• bg-gray-50 border border-gray-200 rounded-md px-3 py-2 text-center
• Do not number them (no 1., 2. prefix — prevents users from thinking order matters)

Copy-all button: "Copy all codes" — text button with clipboard icon, text-indigo-600 hover:text-indigo-700 text-sm font-medium. On click: copies newline-separated codes to clipboard, button text changes to "Copied" for 2 seconds.

Acknowledgment checkbox (required before proceeding):

• Checkbox + label: "I have saved these codes in a secure place. I understand they will not be shown again."
• Checkbox class: rounded border-gray-300 text-indigo-600 focus:ring-indigo-500
• "Enable two-factor authentication" CTA button: disabled (opacity-50 cursor-not-allowed) until checkbox is checked

---

Login Flow — TOTP Step

Login is a two-step flow, not a single form:

Step 1: Email + password fields + "Sign in" button Step 2 (only for TOTP-enrolled users): Separate screen/card with:

• Heading: "Two-factor authentication"
• Helper: "Enter the 6-digit code from your authenticator app."
• Single code input (same spec as enrollment verification above)
• Secondary link below: "Use a backup code instead" — text-sm text-indigo-600 hover:underline
• Back link: "Back to sign in" — text-sm text-gray-500 hover:text-gray-700

Backup code entry: replaces the code input with <input type="text" placeholder="XXXXXXXX"> and label "Enter a backup code". Same error state on invalid/already-used code, generic message: "Invalid or already used code."

The step transition (password accepted → TOTP screen) is NOT a page navigation. The card content swaps in place (v-if swap). URL stays at /login.

---

Loading States

All async actions must show a loading state. Contract:

Action	Loading indicator	Button state
Login submit	Spinner (w-4 h-4, inline left of button label)	disabled, opacity-75
Register submit	Spinner inline	disabled, opacity-75
HaveIBeenPwned breach check	Spinner (w-3 h-3) right-aligned inside input field	Input remains editable
Password reset email send	Spinner inline	disabled, opacity-75
TOTP code verify	Spinner inline	disabled, opacity-75
Admin: create user	Spinner inline	disabled, opacity-75
Admin: deactivate user	Row-level spinner in action column	Row actions pointer-events-none
Admin: reset password	Row-level spinner	Row actions pointer-events-none
Admin: save quota	Spinner inline in edit cell	Save button disabled
Sign-out-all	Spinner inline	disabled, opacity-75

Spinner: animate-spin rounded-full border-2 border-current border-t-transparent — inherits button text color. No external spinner library.

---

Error Message Placement

Error type	Placement	Style
Field validation (required, format, strength)	Inline, below field	mt-1 text-xs text-red-600
Server field error (email taken, invalid creds)	Inline, below affected field	mt-1 text-xs text-red-600
Form-level server error (generic 500, network)	Above the submit button, inside the card	p-3 rounded-lg bg-red-50 border border-red-200 text-sm text-red-700
Session expired (401 on any page)	Toast, top-right, 5s auto-dismiss	bg-gray-900 text-white text-sm px-4 py-3 rounded-lg shadow-lg
Rate limit hit	Inline form-level block	Same as form-level server error, with copy "Too many attempts. Try again in X minutes."
Success (password reset email sent)	Inline, replaces form	p-4 bg-green-50 border border-green-200 text-sm text-green-800 rounded-lg

Security copy rule: Error messages MUST NOT confirm whether an email address exists in the system. Login failure: "Incorrect email or password." Password reset: "If an account exists for that email, you will receive a reset link shortly." — identical response for existing and non-existing emails (anti-enumeration).

---

Auth Page Layout

Auth pages (/login, /register, /reset-password) share a single-column centered layout:

• Page background: bg-gray-50 min-h-screen flex items-center justify-center
• Card: bg-white rounded-2xl shadow-sm border border-gray-200 p-8 w-full max-w-sm
• Logo/brand above card: text-lg font-bold text-indigo-600 tracking-tight centered, mb-6
• Card heading: text-2xl font-bold text-gray-900 mb-1
• Card subheading: text-sm text-gray-500 mb-6
• No sidebar on auth pages — full-width layout

Auth pages are NOT wrapped in the main App.vue sidebar layout. They use a bare layout with no navigation.

---

Account View (/account)

Uses the standard sidebar + main content layout (same as HomeView).

Sections (rendered as stacked cards with space-y-6):

1. Account information — display-only: email, role badge
2. Two-factor authentication — TOTP status + enrollment/disable controls
3. Change password — current password + new password + strength indicator
4. Sessions — "Sign out all devices" with confirmation dialog

Role badge: inline-flex items-center px-2 py-0.5 rounded text-xs font-medium bg-indigo-100 text-indigo-700 for admin; bg-gray-100 text-gray-600 for user.

Sign-out-all confirmation dialog:

• Not a browser confirm(). Rendered as an inline confirmation block that replaces the button on click.
• Copy: "This will sign you out of all devices, including this one. You will need to sign in again."
• Two buttons: "Cancel" (text-gray-600 hover:text-gray-800 text-sm) + "Sign out all devices" (bg-red-600 hover:bg-red-700 text-white text-sm font-medium px-4 py-2 rounded-lg)
• After confirmation: loading state on the destructive button, then redirect to /login

---

Admin View (/admin)

Uses standard sidebar layout. Admin link in AppSidebar.vue visible only when useAuthStore().user?.role === 'admin'. Admin nav link styled identically to other nav links (no special styling — admin access is not advertised).

Sub-navigation (within AdminView):

Horizontal tab strip below the page heading:

• Tab class (default): px-4 py-2 text-sm font-medium text-gray-500 hover:text-gray-700 border-b-2 border-transparent
• Tab class (active): px-4 py-2 text-sm font-medium text-indigo-600 border-b-2 border-indigo-600
• Strip: flex border-b border-gray-200 mb-6
• Tabs: "Users" | "Quotas" | "AI Config"

Users Tab — Table:

Table structure: full-width, divide-y divide-gray-200, inside a bg-white rounded-xl border border-gray-200 overflow-hidden

Columns: Email | Role | Status | Created | Actions

Row state	Background	Status badge
Active user	bg-white	bg-green-100 text-green-700 "Active"
Deactivated user	bg-gray-50	bg-gray-100 text-gray-500 "Deactivated"
Admin user (active)	bg-white	Same as active + role badge

Row text: text-sm text-gray-900 for email, text-sm text-gray-500 for created date.

Actions column (per row): text links, separated by ·

• Active row: "Reset password" · "Deactivate"
• Deactivated row: "Reactivate" (no reset password on deactivated accounts)
• Deactivate link: text-red-600 hover:text-red-700 text-sm
• Other action links: text-indigo-600 hover:text-indigo-700 text-sm

Create User (Users tab):

"Create user" button: positioned top-right of table, bg-indigo-600 hover:bg-indigo-700 text-white text-sm font-medium px-4 py-2 rounded-lg.

Create user form renders as an inline panel above the table (not a modal), with: email field, temporary password field (pre-generated, read-only with copy button), role selector (dropdown: User / Admin).

Quotas Tab — Inline Edit:

Table columns: Email | Used | Limit | Usage % | Actions

Limit field is editable inline. Click "Edit" → limit cell becomes <input type="number" min="1" step="1"> (in MB) with Save / Cancel buttons. Warning shown inline if new limit < current usage: text-xs text-amber-600 mt-1 "New limit is below current usage (X MB). Existing documents will not be deleted, but uploads will be blocked."

AI Config Tab:

Table columns: Email | AI Provider | AI Model | Actions

Provider and model: dropdown selectors (not free-text). Populated from the backend's supported provider list. "Save" button per row. No bulk edit.

---

Sidebar Updates (Phase 2)

AppSidebar.vue gains two additions:

1. Admin link (bottom section, above Settings): conditionally rendered, v-if="authStore.user?.role === 'admin'" — shield SVG icon (w-4 h-4), label "Admin". Same nav-link styling.

2. User identity footer: below the settings link at very bottom.

   • Layout: flex items-center gap-3 px-4 py-3 border-t border-gray-100
   • Avatar: initials-based circle, 32px, bg-indigo-100 text-indigo-700 text-xs font-semibold rounded-full w-8 h-8 flex items-center justify-center shrink-0
   • Email: text-xs text-gray-600 truncate flex-1
   • Sign-out icon button: arrow-right-on-rectangle SVG (w-4 h-4), text-gray-400 hover:text-gray-600

---

Router Guard Feedback

When an unauthenticated user is redirected to /login from a protected route, the login card shows no banner by default. The router saves the redirect query param (/login?redirect=/account). After successful login, the router navigates to the saved route.

If the redirect was triggered by a 401 (token expired, not initial page load), show the session-expired toast (defined in Error Message Placement above) before the redirect completes.

• Never state the number of remaining TOTP attempts
• Admin actions on user rows include the email in the confirmation to prevent mis-clicks, but error responses from the server must not echo credentials back

Registry Safety

Registry	Blocks Used	Safety Gate
shadcn official	none	not applicable — shadcn not installed
