-- Started: Migration from archive-all to selective relay.ngit.dev archive
+### 2026-01-21 [Session 18:00] - Migrating to Selective Archive Service ✅
+- Completed: Migration from archive-all to selective relay.ngit.dev archive
 - Context: grasp-audit package updated with `archiveGraspServices` option
-- Configuration changes made:
+- **Configuration changes made:**
   - Removed: `ngit-grasp-archive-all.nix` (archived all relays)
   - Added: `ngit-grasp-relay-ngit-dev.nix` (archives only relay.ngit.dev)
+  - Updated: `services/default.nix` to import new service file
   - New data directory: `/persistent/grasp/relay-ngit-dev` (was `/persistent/grasp/sync-archive`)
   - New domain: `archive-relay-ngit-dev.internal` (was `archive.internal`)
   - Selective archiving: `archiveGraspServices = [ "relay.ngit.dev" ]`
-- Plan:
-  1. Stop old archive-all service
-  2. Delete old archive-all data directory
-  3. Deploy new selective archive configuration
-  4. Verify new service starts and archives relay.ngit.dev
-- Next: Execute migration steps using subagents
+- **Migration steps executed:**
+  1. ✅ Stopped old archive-all service
+  2. ✅ Deleted old archive-all data directory (freed 5.8GB)
+  3. ✅ Updated NixOS configuration and deployed
+  4. ✅ Created data directory manually (workaround for namespace issue)
+  5. ✅ Verified new service started successfully
+- **Verification results:**
+  - Service status: ✅ Running (active since 16:09:47 CET)
+  - Archive mode: ✅ Confirmed (`archive_all=false`, read_only=true)
+  - Syncing from: ✅ `wss://relay.ngit.dev`
+  - Data archived: ✅ 779MB (and growing)
+  - Git fetches: ✅ Active (fetching repos from relay.ngit.dev)
+  - Service domain: ✅ `archive-relay-ngit-dev.internal`
+  - Port: ✅ 7443 (localhost only)
+- **Disk space:**
+  - Before: 26GB used, 21GB available
+  - After cleanup: 20GB used, 27GB available (5.8GB freed)
+  - Current: 20.8GB used, 26.2GB available (779MB new data)
+- **Issues encountered:**
+  - Mount namespace error on first deployment (data directory didn't exist)
+  - Resolution: Created directory manually, service started successfully
+  - Note: This is a known issue (b454) - module should create directories in ExecStartPre
+- **Migration status:** ✅ **COMPLETE** - Selective archive service operational
