# Issue #41 Verification

Status: already implemented on main

Issue:
- #41 [P3] Service worker: cache crisis resources for offline

Acceptance criteria check:
1. Passed — offline page includes 988 call button, Crisis Text Line, and grounding techniques
2. Passed — service worker precaches `crisis-offline.html`
3. Passed — phone number is clickable via `href="tel:988"`
4. Passed — navigation timeout + offline fallback support intermittent connections

Evidence:
- `sw.js` precaches `/crisis-offline.html`
- `sw.js` contains `NAVIGATION_TIMEOUT_MS` and `AbortController`
- `crisis-offline.html` contains:
  - `href="tel:988"`
  - Crisis Text Line / `741741`
  - grounding prompts for 5-4-3-2-1
- `tests/test_service_worker_offline.py` already exists on main and passes

Verification run from fresh main clone:
- `python3 -m pytest tests/test_service_worker_offline.py -q`
  - `10 passed`

Prior implementation trail:
- Issue comment already states the core implementation is complete on main
- Closed PR #122 documented the already-complete implementation and added the offline guarantees test coverage that is now present on main

Recommendation:
- Close issue #41 as already implemented on main.
