#+TITLE: Session Context - Active Session
#+DATE: 2026-01-23

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

** Key Decisions This Session

*** Project Rename: archangel
- Decided to rename project from "archzfs" to "archangel"
- Script name will be just "archangel" (not install-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: 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] Snapper configuration (manual config - no D-Bus needed in chroot)
- [X] GRUB + grub-btrfs configuration
- [X] Genesis snapshot via btrfs (not snapper, avoids D-Bus)
- [X] VM TEST PASSED @ 23:57 CST

**** Bugs Fixed During Testing
1. GRUB_BTRFS_GRUB_DIRNAME was wrong (/efi/grub -> /boot/grub)
2. snapper create-config needs D-Bus - switched to manual config
3. snapper create needs D-Bus - create genesis snapshot with btrfs command
4. test-install.sh now copies lib/ directory for testing

** Commits This Session
- a49f4b1: Phase 2.1: Implement btrfs support
- (pending): Fix btrfs bugs from VM testing

** Next Steps
1. Commit bug fixes
2. Test btrfs reboot and actual boot from installed system
3. Phase 2.7: Full reboot/snapshot testing
4. Phase 2.8: LUKS encryption

** Notes
- Craig on remote console: 30 lines tall, ~145 columns wide
- Testing approach: syntax first, then full VM test
