+## Proton Mail Bridge Integration
+
+**Explored integrating Proton Mail via the Proton Bridge**
+
+### Bridge Connection Details
+- **IMAP Server**: 127.0.0.1:1143
+- **SMTP Server**: 127.0.0.1:1025
+- **Username**: alexthenerdyai@proton.me
+- **Security**: AUTH=PLAIN (credentials sent in clear over local connection)
+- **Bridge Version**: Proton Mail Bridge 03.22.00 - gluon
+
+### Test Results
+- ✅ Connected successfully to Bridge IMAP
+- ✅ Authenticated with Bridge password
+- ✅ Retrieved folder list (10 folders found)
+- ✅ INBOX has 3 messages, all unread
+
+### Folders Available
+- INBOX
+- Sent
+- Drafts
+- Starred
+- Archive
+- Spam
+- Trash
+- All Mail
+- Folders
+- Labels
+
+### Files Created
+- `tools/proton_imap_test.py` - Initial test script (unicode issues)
+- `tools/proton_imap_simple.py` - Working IMAP test script
+
+### Next Steps
+- Can read emails from INBOX
+- Can search, mark read/unread, move messages
+- Can send emails via SMTP
+- Potential: Daily email digest, notifications, automated responses
+
+---
+
+## Memory Cleanup
+- Corey went through memory files to correct outdated info
+- Updated LAMP Stack Project section (dashboard location corrected)
+- Clean foundation established after 3 OpenClaw installs, 2 OS changes

+## 🏗️ HIERARCHICAL MEMORY SYSTEM — MAJOR ARCHITECTURE CHANGE
+
+**Time:** 2026-02-18 20:42-20:45
+**Source:** https://github.com/ucsandman/OpenClaw-Hierarchical-Memory-System
+**Impact:** TRANSFORMATIVE — 60-70% token reduction on session start
+
+### What We Built
+
+Replaced flat MEMORY.md with **index + drill-down structure**:
+
+**New Directory Structure:**
+```
+memory/
+├── people/
+│   └── corey.md              (user profile, 679 bytes)
+├── projects/
+│   ├── home-assistant.md     (HA project details)
+│   ├── coding-workflow.md    (Git/repos setup)
+│   ├── discord-voice-bot.md  (GLaDOS voice bot)
+│   └── memory-system.md      (meta documentation)
+├── decisions/
+│   └── 2026-02.md            (February decision log)
+└── context/                   (temp files, ready for use)
+```
+
+**MEMORY.md Rebuilt:**
+- **Before:** 5-10k tokens (full detail, everything crammed in)
+- **After:** 2.4k tokens (lightweight index, drill-down references)
+- **Savings:** 60-70% reduction on session start
+- **Drill-down cost:** ~1k per detail file (only when needed)
+
+### Key Features
+
+1. **Trigger Words** — Each entry has keywords for auto-drill
+2. **Active Context Section** — 4 projects always visible in index
+3. **Drill-Down Rules** — Max 5 drill-downs per session
+4. **Hard Cap** — 3k token limit on index
+5. **Integration Points** — Table showing where to find what
+
+### Token Math
+
+| Scenario | Before | After | Savings |
+|----------|--------|-------|---------|
+| Session start | 5-10k tokens | ~2.4k tokens | **70%** |
+| Drill down 1 file | N/A | +~1k tokens | On-demand |
+| Full context | 15-20k tokens | ~5-6k tokens | **65%** |
+
+### Files Created
+
+- `memory/people/corey.md` — User profile extracted
+- `memory/projects/home-assistant.md` — HA project
+- `memory/projects/coding-workflow.md` — Coding setup
+- `memory/projects/discord-voice-bot.md` — Voice bot
+- `memory/projects/memory-system.md` — Meta docs
+- `memory/decisions/2026-02.md` — February decisions
+- `MEMORY_MIGRATION_LOG.md` — Full migration notes
+- `WORKSPACE_STRUCTURE.md` — Quick reference guide
+
+### Cleanup
+
+**Moved to `unused_files/`:**
+- hello.txt
+- ha_entities.csv (replaced by ha_devices.csv)
+- 4x YouTube transcript .vtt files
+
+### Why This Matters
+
+This is **Phase 1 of 4-layer memory**:
+1. ✅ **Hierarchical index** (today) — structured lookups
+2. 🔄 **Vector memory** — fuzzy search (future)
+3. ✅ **Daily logs** — timeline queries (existing)
+4. ✅ **SQLite database** — lesson retrieval (existing)
+
+All complementary, all token-efficient.
+
+### Next Review
+
+Check if index stays under 3k tokens. Archive inactive items if it grows.
