+**Generated:** 2026-04-14
+**Repo:** Timmy_Foundation/the-door
+**Description:** Crisis Front Door — a single URL where a man at 3am can talk to Timmy. No login, no signup. 988 always visible.
+
+---
+
+## Project Overview
+
+The-door is a crisis intervention web application — the most sacred surface in the Timmy Foundation. When a man at 3am reaches the end of his road, this is where he lands. No login, no signup, no barriers. 988 Suicide and Crisis Lifeline always visible. The "When a Man Is Dying" protocol active on every page.

+## Key Abstractions
+
+| Module | Purpose |
+|---|---|
+| `crisis/detect.py` | 4-tier detection: LOW/MEDIUM/HIGH/CRITICAL via regex patterns |
+| `crisis/gateway.py` | HTTP API, Sovereign Heart prompt injection |
+| `crisis/response.py` | Response generation, 988 integration, escalation |
+| `crisis/compassion_router.py` | Profile-based routing (different crisis types) |
+| `sw.js` | Service worker for offline-first PWA |
+
+## Safety Constraints
+
+- **The-door never auto-closes PRs** (in fleet-ops exempt list)
+- **988 always visible** on every page, even offline
+- **When a Man Is Dying protocol** active on every interaction
+- **No login/signup** — zero barriers to crisis support
+- **Offline-first** — service worker caches critical pages
+
+## Test Coverage
+
+| Test | Coverage |
+|---|---|
+| Crisis overlay focus trap | ✅ |
+| Dying detection deprecation | ✅ |
+| False positive fixes | ✅ |
+| Crisis detection tiers | ❌ (in crisis/tests.py) |
+| Response generation | ❌ |
+| Offline service worker | ❌ |
+
+## Security
+
+- No user data stored (crisis intervention is stateless by design)
+- No cookies, no tracking, no analytics
+- Service worker only caches static assets
+- Crisis detection runs client-side where possible
