* Session: Friday 2026-01-23 @ 14:08 CST (continued 2026-01-24)

** Key Decisions This Session

*** Project Rename: archangel
- Decided to rename project from "archzfs" to "archangel"

*** Btrfs Implementation Approach
- Phase 2: Single-disk btrfs, no encryption (test first)
- Phase 2.7: Test basic btrfs before adding encryption
- Phase 2.8: LUKS encryption after basic btrfs works
- Phase 3: Multi-disk (stripe, mirror, raidX) + encrypted/unencrypted

** Work Completed

*** Phase 1: Refactor (COMPLETE)
- [X] lib/common.sh, config.sh, disk.sh, zfs.sh created
- [X] Filesystem selection prompt
- [X] Renamed to archangel
- [X] VM test passed

*** Phase 2.1-2.6: Btrfs Support (COMPLETE)
- [X] Created lib/btrfs.sh with full implementation
- [X] 10 subvolumes matching ZFS dataset layout
- [X] Mount functions with proper options
- [X] fstab generation (subvol= NOT subvolid!)
- [X] GRUB + grub-btrfs configuration with serial console
- [X] Snapper firstboot service (configures on first boot)

*** Phase 2.7: Basic Btrfs Testing (COMPLETE @ 05:23 CST)
- [X] VM boots from installed btrfs disk
- [X] GRUB menu shows and auto-boots
- [X] All 10 subvolumes mount correctly
- [X] Snapper works when configured
- [X] Genesis snapshot can be created
- [X] grub-btrfs detects snapshots

*** Phase 2.8: LUKS Encryption (IMPLEMENTED @ 05:36 CST)
- [X] LUKS functions in btrfs.sh (create, open, close containers)
- [X] crypttab configuration
- [X] encrypt hook for mkinitcpio
- [X] GRUB cryptdevice parameter
- [X] Encryption prompts in archangel
- [X] LUKS_PASSPHRASE config variable
- [X] btrfs-luks.conf test config
- [ ] VM test pending

** Commits This Session
- a49f4b1: Phase 2.1: Implement btrfs support
- 35a661c: Fix btrfs bugs from VM testing
- bd0616c: Fix btrfs GRUB boot and snapper firstboot
- 4a7b6c3: Update session context: Phase 2.7 complete
- (pending): Phase 2.8: Add LUKS encryption for btrfs

** Next Steps
1. VM test LUKS btrfs installation
2. Rebuild ISO with all fixes
3. Full end-to-end automated test
4. Phase 3: Multi-disk support

** Notes
- Craig on remote console: 30 lines tall, ~145 columns wide
- Testing approach: syntax first, then full VM test
- Snapper requires D-Bus - can't configure in chroot, needs firstboot
