Major enhancements to ProtocolAttributes-Spec-vs-AutobahnPython.md:

1. Added comprehensive Table of Contents:
   - Summary sections with links
   - Phase 1 (Pub/Sub) message links
   - Phase 2 (RPC) message links with TODO markers
   - Appendix links

2. Enhanced Summary Matrix:
   - Split into Phase 1 (Complete) and Phase 2 (In Progress)
   - Added CALL.Options and RESULT.Details rows
   - Added placeholders for remaining RPC messages
   - Added Phase 1+2 Summary with compliance/extension analysis

3. Expanded Version Information:
   - Analysis Status: Visual progress tracking with checkmarks/emojis
   - Test Coverage: Detailed test count breakdown
   - Source Information: Complete file paths
   - Related Issues: Links to wamp-proto#556 and autobahn-python#1764

Current status:
- Phase 1 (Pub/Sub): 7 message types ✅ COMPLETE
- Phase 2 (RPC): 2/8 message types complete (CALL, RESULT)
- Total tests: 254 passed, 35 skipped

+### Phase 1+2 Summary
+
+**Spec Compliance:**
+- ✅ Core functionality: All basic profile features implemented
+- ⚠️  Missing disclosure initiation: `disclose_me` not implemented (PUBLISH, CALL)
+- ⚠️  E2EE naming: Uses `enc_*` prefix instead of spec's `ppt_*` prefix
+- ⚠️  Missing E2EE: `ppt_scheme` not implemented (required in spec)
+- ⚠️  Missing trustlevel: `EVENT.Details.trustlevel` not implemented
+
+**Implementation Extensions:**
+- ✅ Router-to-router forwarding: `forward_for` (all messages with Options/Details)
+- ✅ Transaction deduplication: `transaction_hash` (PUBLISH, CALL)
+- ✅ Disclosure metadata: Router-added `publisher*`, `caller*`, `callee*` attributes
+- ✅ Event acknowledgement: `x_acknowledged_delivery` (EVENT - needs naming review)
