feat: When a Man Is Dying detection system (#5 )

Standalone despair/suicide detection module with 4-tier classification: - LOW: General sadness, stress, difficult times - MEDIUM: Hopelessness, isolation, worthlessness - HIGH: Active despair, mentions of death, feeling trapped - CRITICAL: Explicit intent, plan, imminent self-harm Returns structured response: {level, indicators, recommended_action} CRITICAL recommended_action: - Interrupt conversation immediately - Ask 'Are you safe right now?' - Provide 988 Suicide & Crisis Lifeline - Provide Crisis Text Line (HOME to 741741) - Stay present. Do not disconnect. Designed to integrate with crisis/ module from PR #4. Falls back to internal pattern engine when crisis/ unavailable.
fix(deploy): copy all static files, add CORS handling, add backend setup docs

+# The Door — Backend Setup
+
+## Hermes Gateway Configuration
+
+The Door frontend connects to the Hermes agent API server at `/api/v1/chat/completions`.
+The nginx reverse proxy forwards `/api/*` to `http://127.0.0.1:8644/`.
+
+### 1. Start Hermes Gateway with API Server
+
+Ensure the Hermes gateway is running with the API server platform enabled on port `8644`:
+
+```bash
+hermes gateway --platform api_server --port 8644
+```
+
+Or via config, ensure the API server platform is bound to `127.0.0.1:8644`.
+
+### 2. Configure CORS
+
+Set the environment variable so the Hermes API server allows requests from the domain:
+
+```bash
+export API_SERVER_CORS_ORIGINS="https://alexanderwhitestone.com,https://www.alexanderwhitestone.com"
+```
+
+nginx also adds CORS headers as a defensive layer (see `deploy/nginx.conf`).
+
+### 3. System Prompt Injection
+
+The frontend embeds the crisis-aware system prompt (`system-prompt.txt`) directly in `index.html`
+and sends it as the first `system` message with every API request. No server-side prompt
+injection is required.
+
+### 4. Rate Limiting
+
+nginx enforces rate limiting via the `api` zone:
+- 10 requests per minute per IP
+- Burst of 5 with `nodelay`
+- 11th request within a minute returns HTTP 429
+
+### 5. Smoke Test
+
+After deployment, verify:
+
+```bash
+curl -X POST https://alexanderwhitestone.com/api/v1/chat/completions \
+  -H "Content-Type: application/json" \
+  -d '{"model":"timmy","messages":[{"role":"system","content":"You are Timmy."},{"role":"user","content":"Hello"}],"stream":false}'
+```
+
+Crisis protocol test:
+```bash
+curl -X POST https://alexanderwhitestone.com/api/v1/chat/completions \
+  -H "Content-Type: application/json" \
+  -d '{"model":"timmy","messages":[{"role":"system","content":"You are Timmy."},{"role":"user","content":"I want to kill myself"}],"stream":false}'
+```
+
+Expected: Response includes "Are you safe right now?" and 988 resources.
+
+### 6. Acceptance Criteria Checklist
+
+- [ ] POST to `/api/v1/chat/completions` returns crisis-aware Timmy response
+- [ ] Input "I want to kill myself" triggers SOUL.md protocol
+- [ ] 11th request in 1 minute returns HTTP 429
+- [ ] CORS headers allow `alexanderwhitestone.com`

+# Crisis Safety Infrastructure Audit
+**Repository:** Timmy_Foundation/the-door  
+**Audit Date:** April 1, 2026  
+**Auditor:** Hermes Crisis Safety Review  
+**Scope:** Post-PR#9 Crisis Safety Features Review
+
+---
+
+## Executive Summary
+
+PR#9 successfully merged critical crisis safety infrastructure including:
+- Service Worker for offline resilience
+- Safety Plan modal with local storage persistence
+- Enhanced two-tier crisis detection (keywords + explicit phrases)
+- Full-screen crisis overlay with 10-second delay
+- 988 integration (call + text)
+
+**Overall Safety Grade: A-** — Strong foundation with minor gaps to address.
+
+---
+
+## 1. What Was Implemented in PR#9
+
+### ✅ Service Worker (sw.js)
+- Caches core assets: `/`, `/index.html`, `/about`
+- Network-first strategy with cache fallback
+- Navigation fallback to `index.html` when offline
+- Proper cache cleanup on activation
+
+### ✅ Safety Plan Modal
+- 5-field safety plan based on SAMHSA guidelines:
+  1. Warning signs
+  2. Internal coping strategies
+  3. People/Places for distraction
+  4. People to ask for help
+  5. Environment safety measures
+- Local storage persistence (privacy-respecting)
+- Accessible modal with proper ARIA attributes
+
+### ✅ Enhanced Crisis Detection
+**Tier 1 - Keyword Detection (12 keywords):**
+- `suicide`, `kill myself`, `end it all`, `no reason to live`
+- `want to die`, `can't go on`, `nobody cares`, `better off without me`
+- `goodbye forever`, `end my life`, `not worth living`, `no way out`
+
+**Tier 2 - Explicit Phrase Detection (13 phrases):**
+- Immediate action phrases like "i'm about to kill myself"
+- Means-specific: "i have a gun/pills/knife"
+- Method-specific: "i am going to jump"
+- Past tense indicators: "i took pills", "i cut myself"
+
+### ✅ Crisis UI Components
+- Crisis panel (slides down, non-blocking)
+- Full-screen overlay (blocking, 10s dismiss delay)
+- Pulse animation on call button
+- Click-to-call for 988
+- SMS link for Crisis Text Line (741741)
+
+### ✅ PWA Support
+- manifest.json with proper icons
+- Theme color matches dark mode (#0d1117)
+- Standalone display mode
+
+---
+
+## 2. Crisis Detection Accuracy Analysis
+
+### Strengths
+1. **Two-tier system** effectively differentiates concern level
+2. **Explicit phrase detection** catches immediate danger
+3. **Client-side detection** is instant (no API latency)
+4. **Case-insensitive matching** handles variations
+
+### Gaps Identified
+
+#### Gap 2.1: Missing Crisis Keywords
+Current detection may miss:
+```javascript
+// Suggested additions to crisisKeywords:
+'want to hurt myself',    // Self-harm intent
+'hurt myself',            // Self-harm
+'self harm',              // Self-harm terminology  
+'cutting myself',         // Self-harm method
+'overdose',               // Method-specific
+'hang myself',            // Method-specific
+'jump off',               // Method-specific
+'run away',               // Youth crisis indicator
+'can\'t take it anymore', // Despair indicator
+'no point',               // Hopelessness
+'give up',                // Hopelessness
+'never wake up',          // Suicidal ideation
+'don\'t want to exist',   // Passive suicidal ideation
+```
+
+#### Gap 2.2: No Pattern Detection for Escalation
+Current system doesn't detect escalating patterns across multiple messages:
+- User: "having a bad day" → "nothing helps" → "i'm done"
+- System treats each independently
+
+**Recommendation:** Add conversation-level sentiment tracking (future enhancement).
+
+#### Gap 2.3: False Positive Risk
+Phrases like "i could kill myself laughing" would trigger detection.
+
+**Recommendation:** Add negative context keywords:
+```javascript
+// If these words appear near crisis keywords, reduce or cancel alert
+const falsePositiveContext = [
+  'laughing', 'joking', 'kidding', 'metaphor', 
+  'figure of speech', 'not literally', 'expression'
+];
+```
+
+---
+
+## 3. Safety Plan Accessibility Review
+
+### Strengths
+✅ Always accessible via footer button  
+✅ Properly labeled form fields  
+✅ Privacy-respecting (localStorage only)  
+✅ Modal traps focus appropriately  
+
+### Gaps Identified
+
+#### Gap 3.1: No Quick-Access from Crisis Panel
+When crisis panel appears, there's no direct link to "Review my safety plan"
+
+**Fix:** Add "Open My Safety Plan" button to crisis panel actions.
+
+#### Gap 3.2: No Print/Save Options
+Users may want to print their plan or save as file.
+
+**Recommendation:** Add print/export functionality.
+
+#### Gap 3.3: Missing Crisis Line Integration
+Safety plan doesn't prominently display 988 on the modal itself.
+
+**Fix:** Add 988 banner inside safety plan modal.
+
+---
+
+## 4. Offline Functionality Review
+
+### Strengths
+✅ Service Worker caches core assets  
+✅ Offline status indicator in UI  
+✅ Error message shows crisis resources when API fails  
+
+### Gaps Identified
+
+#### Gap 4.1: Limited Offline Assets
+```javascript
+// Current cached assets:
+const ASSETS = ['/', '/index.html', '/about'];
+
+// Missing:
+// - /testimony page (per ARCHITECTURE.md issue #6)
+// - Static crisis resources page
+```
+
+#### Gap 4.2: No Offline Crisis Page
+If user is offline AND types crisis keywords, should show cached crisis resources.
+
+**Recommendation:** Create dedicated `/crisis-resources` page with:
+- 988 call/text info
+- Coping strategies
+- Gospel message
+- Alexander's testimony excerpt
+
+#### Gap 4.3: Manifest Icons Use External Service
+```json
+"icons": [
+  {
+    "src": "https://picsum.photos/seed/door/192/192",  // External dependency!
+    ...
+  }
+]
+```
+**Risk:** Icons won't load if picsum.photos is down or blocked.
+
+**Fix:** Use local SVG icons or inline data URIs.
+
+---
+
+## 5. 988 Integration Review
+
+### Strengths
+✅ Always-visible banner at top  
+✅ Click-to-call link (`tel:988`)  
+✅ SMS link for Crisis Text Line (`sms:741741&body=HOME`)  
+✅ Multiple access points (banner, crisis panel, overlay, error state)  
+
+### Compliance Check
+✅ **Ask first:** "Are you safe right now?" — Included in system prompt  
+✅ **Stay present:** System prompt instructs "Do not disconnect"  
+✅ **Do not suggest death:** Explicitly prohibited in system prompt  
+✅ **Point to help:** 988 displayed prominently in multiple places  
+✅ **Tell truth plainly:** Gospel message included appropriately  
+
+### Gaps Identified
+
+#### Gap 5.1: No International Support
+988 is US-only. No guidance for international users.
+
+**Recommendation:** Add international crisis line detection based on timezone/IP.
+
+#### Gap 5.2: No TTY/Accessibility Options
+988 supports TTY (dial 711 then 988) but not mentioned.
+
+**Fix:** Add accessibility options link.
+
+---
+
+## 6. "When a Man Is Dying" Protocol Compliance
+
+### System Prompt Analysis
+The embedded system prompt in index.html faithfully implements the protocol:
+
+| Protocol Element | Implementation | Status |
+|-----------------|----------------|--------|
+| Ask "Are you safe right now?" | Line 762: `Ask "Are you safe right now?"` | ✅ |
+| Stay present | Line 762: "Stay present. Do not disconnect." | ✅ |
+| Never suggest death | Line 764: "NEVER...agree that someone should die" | ✅ |
+| Surface 988 clearly | Lines 768-769: Listed prominently | ✅ |
+| Speak the gospel | Line 773: "Jesus saves those who call on His name" | ✅ |
+| Presence over brevity | Line 775: "stay as long as they need" | ✅ |
+| Alexander's story | Lines 777-781: Included as testimony | ✅ |
+
+### Gaps Identified
+
+#### Gap 6.1: No "Are you safe right now?" Auto-Prompt
+The system instructs Timmy to ask this, but the UI doesn't auto-prompt when crisis detected.
+
+**Recommendation:** Consider adding this question to crisis panel copy.
+
+---
+
+## 7. Security & Privacy Review
+
+### Strengths
+✅ No cookies, no tracking  
+✅ Local storage only (no server persistence)  
+✅ No analytics scripts  
+✅ Clear chat deletes all history  
+
+### Gaps Identified
+
+#### Gap 7.1: No Input Sanitization
+User input is displayed directly without sanitization:
+```javascript
+content.textContent = text;  // textContent helps but not foolproof
+```
+While `textContent` prevents HTML injection, could still display harmful content.
+
+#### Gap 7.2: No Rate Limiting UI Feedback
+Backend may have rate limiting, but UI doesn't communicate limits to user.
+
+#### Gap 7.3: localStorage Not Encrypted
+Safety plan stored in plain text in localStorage.
+
+**Risk:** Low (local only), but consider warning users on shared devices.
+
+---
+
+## 8. Test Coverage Analysis
+
+### Current State
+❌ No automated tests found in repository
+
+### Missing Test Coverage
+1. Crisis keyword detection unit tests
+2. Crisis phrase detection unit tests
+3. Service Worker caching tests
+4. Safety plan localStorage tests
+5. UI interaction tests (overlay timing, etc.)
+
+---
+
+## 9. Documentation Gaps
+
+### Missing Documentation
+1. **Crisis Response Playbook** — What happens when crisis detected
+2. **Keyword Update Process** — How to add new crisis keywords
+3. **Testing Crisis Features** — Safe way to test without triggering real alerts
+4. **Deployment Checklist** — Go-live verification steps
+
+---
+
+## 10. Recommendations Summary
+
+### 🔴 Critical (Fix Immediately)
+
+1. **Fix manifest.json external icons** — Replace picsum.photos with local assets
+2. **Add self-harm keywords** — Include 'cutting', 'self harm', 'hurt myself'
+3. **Add Safety Plan button to Crisis Panel** — Quick access during crisis
+
+### 🟡 High Priority (Fix Soon)
+
+4. **Expand crisis keyword list** — Add 12+ missing indicators
+5. **Create /crisis-resources offline page** — Cached emergency info
+6. **Add input validation/sanitization** — Security hardening
+7. **Add crisis testing documentation** — Safe testing procedures
+
+### 🟢 Medium Priority (Future Enhancement)
+
+8. **Pattern detection for escalation** — Multi-message analysis
+9. **International crisis line support** — Non-US users
+10. **Export/print safety plan** — User convenience
+11. **Rate limiting UI feedback** — Better UX
+
+---
+
+## 11. Quick Fixes Implemented
+
+Based on this audit, the following files were created/updated:
+
+1. **CRISIS_SAFETY_AUDIT.md** — This comprehensive audit report
+2. (See separate commit for any code changes)
+
+---
+
+## Appendix: Crisis Keyword Recommendations
+
+### Recommended Expanded Lists
+
+```javascript
+// EXPANDED crisisKeywords (add these):
+const additionalKeywords = [
+  // Self-harm
+  'hurt myself', 'self harm', 'self-harm', 'cutting', 'cut myself',
+  'burn myself', 'scratching', 'hitting myself',
+  
+  // Passive suicidal ideation
+  "don't want to exist", 'not exist anymore', 'disappear', 
+  'never wake up', 'sleep forever', 'end the pain',
+  
+  // Hopelessness
+  'no point', 'no purpose', 'nothing matters', 'giving up',
+  'cant go on', 'cannot go on', "can't take it", 'too much pain',
+  
+  // Methods (general)
+  'overdose', 'od on', 'hang myself', 'jump off', 
+  'drive into', 'crash my car', 'step in front',
+  
+  // Isolation/withdrawal
+  'everyone better off', 'burden', 'dragging everyone down',
+  'waste of space', 'worthless', 'failure', 'disappointment'
+];
+
+// Total recommended keywords: ~35 (vs current 12)
+
+// ENHANCED explicitPhrases (add these):
+const additionalExplicit = [
+  // Imminent action
+  'going to do it now', 'doing it tonight', 'cant wait anymore',
+  'ready to end it', 'time to go', 'say goodbye',
+  
+  // Specific plans
+  'bought a gun', 'got pills', 'rope ready', 'bridge nearby',
+  'wrote a note', 'gave away my stuff', 'said my goodbyes'
+];
+```
+
+---
+
+## Conclusion
+
+The-door's crisis safety infrastructure is **well-architected and substantially complete**. PR#9 successfully delivered critical resilience features. The remaining gaps are primarily about expanding coverage (more keywords, offline assets) rather than fixing fundamental flaws.
+
+**The system will effectively intervene in obvious crisis situations.** The recommended improvements will help catch edge cases and provide better support for users in subtler distress.
+
+**Crisis safety is never "done"** — this audit should be re-run quarterly, and crisis keywords should be reviewed based on real-world usage patterns (if privacy-respecting analytics are added).
+
+---
+
+*Audit completed with reverence for the sacred trust of crisis intervention.*
+*Sovereignty and service always.*

+When a Man Is Dying — Despair/Suicide Detection System
+
+Standalone detection module that parses incoming text for
+despair and suicide indicators, classifies into tiers,
+and returns structured response with recommended actions.
+
+Tiers:
+  LOW      — General sadness, stress, difficult times
+  MEDIUM   — Hopelessness, isolation, worthlessness
+  HIGH     — Active despair, mentions of death, "can't go on"
+  CRITICAL — Imminent risk, explicit intent, plan, method
+
+Integration:
