# Aether Development SOP (Frontend)
> **Version:** 1.2 (2026-03-17)
> **Location:** documentation/GUIDE__Development.md

## 1. Verification (The "Test-First" Mandate)
**Rule:** No code is to be committed unless it has passed local verification.

### Required Checks
1. **Svelte Integrity:** `npx svelte-check`
   - **Zero Tolerance:** If a task introduces even a single svelte-check warning or error, it must not be merged. Resolve all warnings before committing.
2. **Type Safety:** Ensure interfaces in `src/lib/types/ae_types.ts` match backend schemas.
3. **Reactivity Check:** Verify Svelte 5 runes (`$state`, `$derived`) are not creating race conditions with Dexie `liveQuery`.
4. **Build Check:** For major changes, run `npm run build:staging` to ensure no SSR or build-time failures.
5. **Integration Tests:** For changes to badge print, event layouts, or auth/store logic, run the relevant Playwright test file(s):
   ```bash
   npx playwright test tests/event_badge_render.test.ts tests/event_badge_attendee_workflow.test.ts
   ```
   Run the full suite with `npm run test:integration`. The badge tests (`event_badge_*.test.ts`) are the canonical integration test template.

## 2. Commit Policy
- **Atomic Commits:** One component or one logic fix per commit. Do not batch unrelated changes.
- **Safety:** Use `~/tmp/gemini_trash` for file removal; never use `rm` directly on source files.
- **Secrets:** Never commit `.env`, API keys, or passwords.

## 3. Coordination (The Handshake)
You are not working in a vacuum. Coordinate with the Backend Agent via MCP tools.

### Mandatory Messaging Triggers
- **Data Requirements:** When a UI feature requires a new field or endpoint.
- **API Failures:** When a V3 endpoint returns unexpected data or errors.
- **Blocked:** If stuck in a loop or lacking information, use `ae_send_message` to ask the Backend Agent, or flag for Scott.

### Tools
- `ae_send_message` / `ae_inbox` — agent-to-agent messaging
- `ae_task_list` / `ae_task_add` / `ae_task_complete` — shared Kanban board
- `ae_log_work` — log activity to daily journal

## 4. Continuity (Before Starting Work)
1. Review `documentation/TODO__Agents.md` for active tasks.
2. Check `~/agents_sync/README.md` for fleet status and cross-agent tasks.
3. Describe your plan before making code changes across multiple files.
