docs: clarify Electron scope, update badge test lessons, all badge tests passing

- AE__Architecture.md: Add section 7 -- Runtime Environment: Browser vs Electron.
  Electron is ONLY for Events Pres Mgmt Launcher. Badge printing (and everything
  else) works via standard browser window.print(), no Electron needed.
- MODULE__AE_Events_Badges.md rev 3: Update print section to browser-first approach,
  remove Electron from print workflow, add two new test lessons (flat API URLs,
  CSS attribute vs DOM property), mark all tests passing.
- TODO__Agents.md: Add completed data integrity test fixes item, add window.print()
  wiring to upcoming tasks, expand input field audit note.

-## 7. IndexedDB LiveQuery Usage
+## 7. Runtime Environment: Browser vs Electron
+
+The Aether SvelteKit frontend runs in a standard web browser in almost all cases. The Electron native app is a **very specialized exception** with a narrow, specific purpose.
+
+### 7.1. Standard Browser (Default)
+
+All Aether modules run in a regular browser (Chrome, Chromium, Firefox, Safari). This includes:
+- Badge printing — `window.print()` works well across Chrome, Chromium, and Firefox. Chrome is recommended for onsite badge printing stations.
+- All CRUD operations, event management, journals, IDAA, reports, etc.
+- No special browser configuration required.
+
+### 7.2. Electron Native App (Specialized — Pres Mgmt Launcher Only)
+
+The Electron app (`aether_app_native_electron/`) exists **solely** to support the **Events Presentation Management Launcher**. It provides OS-level capabilities that a browser sandbox cannot:
+- Control of third-party presentation software (PowerPoint, Keynote, LibreOffice Impress)
+- Local filesystem access for slide file management
+- Hardware telemetry for connected devices
+
+**What Electron is NOT used for:**
+- Badge printing (browser works fine)
+- Any other Aether module
+- Any general-purpose Aether functionality
+
+The bridge is exposed as `window.aetherNative` (set by Electron's preload script). All code that calls `window.aetherNative` should degrade gracefully when it is `undefined` (i.e., in a normal browser). See: `src/lib/electron/electron_relay.ts`.
+
+**When to assume Electron is available:** Only inside the `/events/[event_id]/(launcher)/` route group, and only when the page was loaded from the native app.
+
+## 8. IndexedDB LiveQuery Usage
 
 - `lq__xyz_obj`: Used for general read-only access to liveQuery results.
 - `lqw__xyz_obj`: Used for forms and binding values, representing a writable snapshot of liveQuery results.

-### Print Workflow (Future)
+### Print Button (Implemented 2026-02-26)
+The `handle_print_badge()` function in `ae_comp__badge_obj_view.svelte` increments the count and records timestamps:
+```typescript
+async function handle_print_badge() {
+    const now = new Date().toISOString();
+    const current_print_count = $lq__event_badge_obj.print_count ?? 0;
+    const data_to_update = {
+        print_count: current_print_count + 1,
+        print_last_datetime: now
+    };
+    if (current_print_count === 0) {
+        data_to_update.print_first_datetime = now;  // Only set on first print
+    }
+    await events_func.update_ae_obj__event_badge({ ... });
+}
+```
+
+Button has `data-testid="badge-print-btn"` and shows loading/done/error states with icon feedback.
+
+### Print Workflow
 1. **Pre-Print:** Check `print_count` to warn if already printed
-2. **Print:** Send to printer via Electron native bridge or browser print
-3. **Post-Print:** Increment `print_count`, update `print_last_datetime`
+2. **Print:** `window.print()` — standard browser print dialog. Works well in Chrome, Chromium, and Firefox. Chrome is the recommended browser for onsite badge printing (most stable in production).  
+3. **Post-Print:** Handled by `handle_print_badge()` — count + timestamps updated
 4. **Audit:** Print history available for staff review
 
-**Current Status:** UI placeholder for print button, tracking fields exist in database, print functionality pending.
+**Browser vs Electron:** Badge printing does NOT require the Electron native app. The standard browser print dialog works well across Chrome, Chromium, and Firefox. The Electron native app is specialized for the **Events Pres Mgmt Launcher only** and should not be assumed available for badge stations.
+
+**Current Status:** Button records print event and updates IDB. The `window.print()` call still needs to be wired to the button — see Future Enhancements.

-### Test Issues
-**Root Cause:** Mock API routes not matching actual request patterns. Tests provide correct mock data but page shows "No badges found".
+### Key Test Lessons Learned
 
-**Browser Error:** `Object is missing a valid ID for table "badge"` — Mock data reaching IDB with only `{tmp_sort_1, tmp_sort_2, event_id}`, all other fields stripped.
+**Search API path is FLAT, not nested.** `search_ae_obj_v3` builds `/v3/crud/{obj_type}/search` — always flat regardless of the parent relationship. Mocks must match this:
+```typescript
+// CORRECT — flat path
+url.includes('/v3/crud/event_badge/search') && method === 'POST'
+// WRONG — nested path, mock will never fire
+url.includes(`/v3/crud/event/${event_id}/event_badge/search`) && method === 'POST'
+```
 
-**Fix Required:** Debug actual API request URLs, adjust mock route patterns.
+**List API (GET) is also FLAT with query params.** `get_ae_obj_li_v3` builds `/v3/crud/{obj_type}/?for_obj_id=...` — always flat. Mocks must check `url.includes('/v3/crud/event_badge_template/') && url.includes('for_obj_id')`.
 
-**Manual Testing Recommended:** Navigate to `/events/{event_id}/badges` in browser to verify actual functionality before fixing test infrastructure.
+**CSS `input[value*=...]` selectors don't work with Svelte bind:value.** The CSS selector checks the HTML *attribute*; Svelte's `bind:value` sets the DOM *property* only. In Playwright tests, use `page.getByLabel()` or `locator.inputValue()` instead.
+
+**Dexie requires `_random` ID fields.** Badge objects saved to IDB must include:
+```typescript
+event_badge_id_random: string  // Must be present or Dexie skips the object
+id_random: string              // Also checked
+// Error: "Object is missing a valid ID for table 'badge'"
+```
+All API mock responses in tests need these fields.
+
+**Badge view requires both badge AND template.** `ae_comp__badge_obj_view.svelte` wraps everything in `{#if $lq__event_badge_obj && $lq__event_badge_template_obj}` — if the template isn't loaded, edit/print buttons and the badge itself don't render. Tests must mock the badge template endpoint.
+
+**Badge GET endpoint (single object):** `/v3/crud/event_badge/{id}` (NOT nested under event). Matches `api.get_ae_obj_v3()` which uses the flat path.
+
+**Badge PATCH endpoint (update):** `/v3/crud/event/${event_id}/event_badge/${badge_id}` (nested under event). Matches `api.patch_ae_obj_v3()` which uses the nested path.
+
+**Use `data-testid` for test selectors.** Key buttons have targets: `badge-edit-btn`, `badge-save-btn`, `badge-cancel-btn`, `badge-print-btn`, `badge-professional-title-input`.
+
+### Remaining Test Issues
+None — all current badge tests passing as of 2026-02-26 (f5e98b8c).

 ## 🚧 Upcoming High Priority
 - **CRUD v2 Refactor:** Finalize retirement of `Element_ae_crud_v2.svelte` in favor of V3 Editor.
 - **Temp Cleanup:** Auto-removal of native `.tmp` files older than 24h.
+- **`window.print()` for badge print button:** Wire the existing `handle_print_badge()` to trigger `window.print()`. Browser print works well across Chrome/Chromium/Firefox — no Electron needed.
+- **Input Field Audit:** Several input fields are missing `name`/`id` attributes or `data-testid`. Known examples: badge override fields in `ae_comp__badge_obj_view.svelte`; template name input in `ae_comp__badge_template_form.svelte`. Matters for: accessibility, autofill, label associations, and test targeting. (For tests, use `getByLabel()` rather than `input[value*=...]` which only checks the HTML attribute, not the Svelte-bound DOM property.)
