PROJECT: AE Events Badges — Review Form & Print Font Controls

Created: 2026-02-27 Last Updated: 2026-02-27 Branch: ae_app_3x_llm Priority: HIGH — first live event is Axonius, NYC, mid-April 2026 Owner: Scott Idem / One Sky IT Status: ✅ TASK 1 (Badge Review Form) COMPLETE | ✅ TASK 2 (Print Font Controls) COMPLETE — v1

---

Implementation Status (2026-02-27)

✅ TASK 1: Badge Review Form — COMPLETE

The badge review form (ae_comp__badge_review_form.svelte) is now fully functional with:

• ✅ All editable fields with access-level gating
• ✅ Print status display section
• ✅ QR code generation and display (hover zoom + click expand)
• ✅ Options and Tickets fields (staff edit / attendee view)
• ✅ Save/Cancel with change detection
• ✅ Override field revert buttons
• ✅ HTML rendering for full_name, professional_title, affiliations, location
• ✅ Accessibility toggle for text enlargement (text-2xl ↔ text-4xl)
• ✅ Help modal with 6 sections of attendee guidance (Flowbite Modal component)
• ✅ Local edit mode (never writes to $ae_loc.edit_mode)

Bug fixed (2026-02-27): default_authenticated_fields and default_trusted_fields in review/+page.svelte had incorrect field names causing can_edit() to silently drop saves. Fixed to use exact names matching the form's can_edit() checks.

✅ TASK 2: Badge Print Font Controls — COMPLETE (v1)

Implemented in commit 3d7279da. This is a first draft — auto font scaling using mm/inch units is planned as a future iteration.

What was built:

• ae_comp__badge_obj_view.svelte: 4 new optional props (font_size_name, font_size_title, font_size_affiliations, font_size_location, all number in px). When provided, replaces auto inch-based Tailwind class sizing with an inline font-size: Npx style. Existing auto-sizing behavior is completely unchanged when props are absent.
• print/+page.svelte: Screen-only (print:hidden) control panel with 4 rows, one per field. Each row: label, [−] button, value display (58px or Auto), [+] button, [↺] reset. Step: 2px. null state = auto (uses existing inch-based auto-sizing). First + click activates at a sensible default that approximates the current auto inch values.

Default px values when first activated (≈ inch equivalents at 96dpi):

Field	Default px	Approx. inch	Range
Name	58px	≈ .60in	20–80px
Title	34px	≈ .35in	14–56px
Affiliations	38px	≈ .40in	14–60px
Location	34px	≈ .35in	14–56px

Future: Auto font scaling using mm/inch units (physical paper stock measurements). Will likely need to revisit the inch ↔ mm conversion and potentially expose the auto-sizing logic as adjustable rather than replacing it with px overrides.

Context

The Events Badges module is mostly complete for navigation and search. Two key pieces of functional UI were needed before the first show:

1. Badge Review Form ✅ — ae_comp__badge_review_form.svelte now has complete field rendering, edit inputs gated by access level, save/cancel API calls, and display-only sections (QR code, print status, option/ticket checkmarks). Also includes accessibility features (text enlargement) and help modal for attendee guidance.

2. Badge Print Font Controls ⏳ — The print page header needs screen-only controls (hidden during window.print()) to bump font sizes for the name, professional title, affiliations, and location sections before printing. These only affect the ae_comp__badge_obj_view.svelte render — not the page layout/template structural dimensions.

Read documentation/MODULE__AE_Events_Badges.md for full module context before starting.

---

MANDATORY: Before You Start

1. Run ae_describe event_badge (MCP tool) to confirm which fields actually exist in the DB. Several fields in the spec below may need to be added to properties_to_save in src/lib/ae_events/ae_events__event_badge.ts if they are not already saved to IDB.

2. Fields to specifically confirm exist in event_badge schema:

   • pronouns, pronouns_override
   • phone, phone_override
   • allow_tracking
   • agree_to_tc
   • other_1_code through other_8_code (the "option" fields)
   • ticket_1_code through ticket_8_code
   • registration_type, registration_type_code
   • registration_type_override, registration_type_code_override

3. Run npx svelte-check before committing. Baseline is 77 errors (all pre-existing, none in the badge module files). Do not introduce new errors.

4. Do NOT write to $ae_loc.edit_mode from any badge component. This was a critical bug (fixed 2026-02-27). See documentation/AE__Permissions_and_Security.md.

TASK 1: Badge Review Form (HIGH PRIORITY)

File to build

src/routes/events/[event_id]/(badges)/badges/[badge_id]/ae_comp__badge_review_form.svelte

This component is already imported and used by review/+page.svelte. Props it receives:

interface Props {
    event_id: string;
    event_badge_id: string;
    lq__event_badge_obj: any;       // Svelte 5 store from liveQuery
    can_edit_fields: string[];      // Which fields this user can edit
    is_staff: boolean;              // True if trusted_access or higher
    log_lvl?: number;
}

can_edit_fields values:

• ['*'] — administrator (all fields)
• Array of field names — specific editable fields
• [] — read-only (shouldn't normally reach this component, but handle it)

Helper

Use a helper derived inside the component:

function can_edit(field: string): boolean {
    return can_edit_fields.includes('*') || can_edit_fields.includes(field);
}

Save / Cancel Pattern

Follow the Journals module pattern (src/lib/ae_journals/). Key points:

• Use import { events_func } from '$lib/ae_events_functions'
• Call events_func.update_ae_obj__event_badge({ event_badge_id, event_id, data_kv })
• Only send changed fields in data_kv (compare against $lq__event_badge_obj values)
• Show save/cancel buttons only when something has changed (has_changes derived)
• Show a success/error state briefly after save (1-2 seconds, then reset)
• Cancel resets local state back to $lq__event_badge_obj values
• Use data-testid="badge-review-save-btn" and data-testid="badge-review-cancel-btn"

Save API Call

await events_func.update_ae_obj__event_badge({
    api_cfg: $ae_api,  // from ae_loc store or passed as prop — check how ae_comp__badge_obj_view.svelte does it
    event_badge_id: event_badge_id,
    event_id: event_id,
    data_kv: { /* only changed fields */ }
});

Check ae_comp__badge_obj_view.svelte for the existing save pattern — it already works and can be used as reference.

---

Section 1: Display-Only Status Bar (all access levels) ✅ IMPLEMENTED

Always show at top of form. Read-only. No edit controls.

Print Status: [Not yet printed] OR [Printed 3× — first: Jan 5 2026, last: Jan 5 2026]

Implemented: Shows print count with first/last print datetimes. Hidden if print_count < 1. Uses $lq__event_badge_obj.print_count, print_first_datetime, print_last_datetime. Format datetimes with ae_util.iso_datetime_formatter(dt, 'datetime_iso_12_no_seconds'). Import ae_util from $lib/ae_utils/ae_utils.

---

Section 2: QR Code (all access levels) ✅ IMPLEMENTED

Display the attendee's badge QR code. This is the same QR code shown on the printed badge itself — scanning it at the badge station triggers automatic badge search and print.

Implemented using core_func.js_generate_qr_code():

qr_data_url = await core_func.js_generate_qr_code('obj', {
  obj_type: 'event_badge',
  obj_id: event_badge_id
});

Features:

• Hover: Zoom overlay effect (qr_hovered state)
• Click: Expand/collapse that pushes content down (qr_expanded state)
• Displays as data URL image from QR code generation
• Reactive: automatically regenerates when event_badge_id changes

---

Section 3: Editable Fields ✅ IMPLEMENTED

Render each field as: read-only display when !can_edit(field), or an <input> / <select> / <textarea> when can_edit(field).

Show (overridden) label next to override fields when the override value differs from the base field value.

HTML Rendering (implemented 2026-02-27): The following fields render HTML markup using {@html} when viewing (not when editing):

• full_name_override / full_name
• professional_title_override / professional_title
• affiliations_override / affiliations
• location_override / location

This allows for rich text formatting (bold, italic, line breaks, etc.) in badge displays.

Accessibility Features (implemented 2026-02-27):

• Text enlargement toggle button in sticky header
• Normal size: text-2xl on field values
• Enlarged size: text-4xl on field values
• Button shows visual feedback (gray → blue, "Larger" → "Normal" label)
• Applied consistently across all text fields

Help Modal (implemented 2026-02-27):

• Flowbite Modal component with 6 sections
• Sections: Reviewing Badge, Editing Info, Accessibility, QR Code, Lead Scanning, Assistance
• Triggered by Help button (BadgeQuestionMark icon) in sticky header
• Currently has placeholder text — can be customized per event/client

Attendee-Editable Fields (shown to all access levels with link)

Field	Input Type	Notes
pronouns_override	text input	Fallback display: pronouns
full_name_override	text input	Fallback display: full_name; renders HTML when viewing
professional_title_override	text input	Fallback display: professional_title; renders HTML when viewing
affiliations_override	textarea	Fallback display: affiliations; renders HTML when viewing
phone_override	text input (tel)	Fallback display: phone
location_override	text input	Fallback display: location; renders HTML when viewing
allow_tracking	checkbox	Label: "Allow exhibitor lead scanning"
agree_to_tc	checkbox	Label: "I agree to the Terms and Conditions" + placeholder T&C text block

Staff-Only Additional Fields (shown when is_staff === true) ✅ IMPLEMENTED

Field	Input Type	Notes
email_override	email input	Fallback display: email
badge_type_code_override	select	Options: member, non-member, guest, exhibitor, staff, test; also updates badge_type_override text
registration_type_code_override	select	Same options as badge_type for now; also updates registration_type_override
hide	checkbox	Label: "Hidden from search results"
priority	number input
notes	textarea

Staff-Only: Options & Tickets (read-edit, shown when is_staff === true) ✅ IMPLEMENTED

Other/Options (other_1_code through other_8_code):

• If field has a value: show as editable text input with label "Option X"
• If field is empty/null: show faintly as "Option X (empty)" — staff can still set it
• These represent event-specific add-ons or membership indicators

Tickets (ticket_1_code through ticket_8_code):

• Same pattern as options above, label "Ticket X"

Attendee-Only: Options & Tickets (display only) ✅ IMPLEMENTED

When !is_staff and the field has a value: show [✓] Option X or [✓] Ticket X. When the field is empty: hide entirely (attendees don't see empty slots).

---

Section 4: Terms & Conditions Block (all, only when agree_to_tc in can_edit_fields) ✅ IMPLEMENTED

Placeholder text for now:

By checking this box, I confirm that the information on my badge is correct to the best
of my knowledge. I agree that this badge may be used for identification purposes during
the event and that my attendance may be recorded by exhibitors using the lead scanning
feature if I permit it.

Show this before the agree_to_tc checkbox. If agree_to_tc is not in can_edit_fields, hide the entire block.

---

Field State Pattern (Svelte 5 runes)

// Initialize local editable state from badge object
let local_full_name_override = $state($lq__event_badge_obj?.full_name_override ?? '');
let local_pronouns_override = $state($lq__event_badge_obj?.pronouns_override ?? '');
// ... etc for each editable field

// Detect changes
let has_changes = $derived(
    local_full_name_override !== ($lq__event_badge_obj?.full_name_override ?? '')
    || local_pronouns_override !== ($lq__event_badge_obj?.pronouns_override ?? '')
    // ... etc
);

// Build changed-fields-only payload
function build_save_payload(): Record<string, any> {
    const payload: Record<string, any> = {};
    if (local_full_name_override !== ($lq__event_badge_obj?.full_name_override ?? ''))
        payload.full_name_override = local_full_name_override || null;  // empty string → null
    // ... etc
    return payload;
}

Important: Empty string inputs should save as null (clears the override, falls back to base field). Use value || null in the payload.

TASK 2: Badge Print Font Size Controls (MEDIUM PRIORITY)

Where to add

src/routes/events/[event_id]/(badges)/badges/[badge_id]/print/+page.svelte

Add a screen-only (print:hidden) control panel between the header and the badge render. This panel lets staff adjust font sizes for the four text-heavy sections before clicking Print.

Controls needed

Font Size Controls (screen only, hidden during print):
[Name]     [−] [14px] [+]
[Title]    [−] [12px] [+]
[Affiliations] [−] [11px] [+]
[Location]     [−] [10px] [+]

• Start with sensible defaults (match what ae_comp__badge_obj_view.svelte currently uses)
• Min/max per field (e.g., 8px–24px for name, 7px–18px for others)
• Pass the sizes as props into ae_comp__badge_obj_view

Props to add to ae_comp__badge_obj_view.svelte

ae_comp__badge_obj_view.svelte currently has internal font size logic. It needs to accept optional override props:

// New optional props:
font_size_name?: number;            // px
font_size_title?: number;           // px
font_size_affiliations?: number;    // px
font_size_location?: number;        // px

When these props are provided, use them instead of the internally computed sizes. When not provided, fall back to existing auto-sizing behavior.

IMPORTANT: Do NOT touch structural dimensions (overall badge width/height, header/footer sizes, template layout). Only the text content font sizes.

is_staff prop on the review form = administrator_access || trusted_access.

Patterns to Follow

• Canonical module reference: src/lib/ae_journals/ — most complete, most advanced
• Svelte 5 runes: $state, $derived, $derived.by(), $effect — no legacy $: syntax
• Icons: Lucide Svelte only — import { Save, X, Check, ... } from 'lucide-svelte'
• No Font Awesome (fas fa-*) anywhere in the badge module
• Styling: Tailwind CSS v4 + Skeleton UI utility classes (btn, preset-tonal-*, input, card)
• Commits: Atomic — one component per commit; run npx svelte-check before every commit

---

What NOT to Do

• Do NOT touch @page CSS or badge template structural dimensions — print layout is out of scope
• Do NOT write to $ae_loc.edit_mode from any component
• Do NOT connect mod_badges_json.edit_permissions yet — hardcoded field lists are intentional for now
• Do NOT implement the email API — send_review_email() placeholder stays as alert()
• Do NOT add person_passcode DB field — out of scope for this sprint

---

Testing

Run existing badge tests after any changes:

npm run test:unit
npx playwright test tests/events/badges/

Baseline: all badge tests passing as of 2026-02-26 (f5e98b8c).

Add data-testid attributes to key interactive elements:

• badge-review-save-btn
• badge-review-cancel-btn
• badge-review-full-name-input
• badge-review-agree-to-tc-checkbox
