+# Trigger Word Enforcement Architecture
+
+## Problem
+Claude failed to recognize "ffs" code word despite inst_082 being active. This was a **trigger recognition failure**, not a missing instruction issue.
+
+## Root Cause
+- inst_082 (ffs trigger) exists and is marked active: true
+- inst_078 (ff trigger) exists and is marked active: true
+- Both are HIGH persistence, SYSTEM quadrant
+- scripts/framework-stats.js and scripts/framework-audit-response.js both exist
+- **BUT**: No architectural enforcement to ensure Claude checks for trigger words on EVERY user message
+
+## Solution
+Created `.claude/hooks/trigger-word-checker.js` that runs on every user prompt submission:
+
+```javascript
+// Detects:
+// - "ffs" (exact match or word boundary) → framework-stats.js
+// - "ff " (prefix) → framework-audit-response.js
+```
+
+Registered in `.claude/settings.json`:
+```json
+"UserPromptSubmit": [
+  {
+    "hooks": [
+      {
+        "type": "command",
+        "command": "\"$CLAUDE_PROJECT_DIR\"/.claude/hooks/trigger-word-checker.js",
+        "timeout": 2
+      }
+    ]
+  }
+]
+```
+
+## How It Works
+
+1. **User types "ffs"**
+2. Hook runs BEFORE Claude processes the message
+3. Hook outputs: `⚠️ CODE WORD DETECTED: "ffs"`
+4. Hook provides instruction: `Claude MUST run: node scripts/framework-stats.js`
+5. Claude sees the hook output and executes the command
+
+## Testing
+
+```bash
+# Test ffs trigger
+node .claude/hooks/trigger-word-checker.js '{"text":"ffs"}'
+# Output: ⚠️ CODE WORD DETECTED: "ffs"
+#         Claude MUST run: node scripts/framework-stats.js
+
+# Test ff trigger
+node .claude/hooks/trigger-word-checker.js '{"text":"ff what are the boundary rules?"}'
+# Output: ⚠️ CODE WORD DETECTED: "ff"
+#         Claude MUST run: node scripts/framework-audit-response.js --prompt "..." --type "boundary_question"
+
+# Test normal message (no output)
+node .claude/hooks/trigger-word-checker.js '{"text":"please fix the bug"}'
+# (silent - no trigger detected)
+```
+
+## Philosophy
+**Governance is enforced architecturally, not documented.**
+
+Relying on voluntary compliance (Claude remembering to check for triggers) = framework fade.
+Architectural enforcement (hook that runs on EVERY message) = reliable governance.
+
+## Files Modified
+- `.claude/hooks/trigger-word-checker.js` - New hook script
+- `.claude/settings.json` - Registered UserPromptSubmit hook

+## Future Enhancements
+If Claude Code doesn't support UserPromptSubmit hooks natively:
+1. Add to session-init.js output as prominent reminder
+2. Create a PreToolUse hook that checks user's last message
+3. Add to system prompt injection if hook system insufficient
