* 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)
- Checked for conflicts: pwnerfly/Archangel is dead (2020, 0 stars, no license)
- Name is clear for use

** Work Completed

*** 1. Btrfs Implementation Planning
- Created docs/PLAN-archangel-btrfs.org with 6-phase implementation
- Expanded testing validation checks in research doc
- Decided: snapper for snapshots, GRUB for btrfs boot

*** 2. Phase 1: Refactor (COMPLETE)
**** Phase 1.1: lib/ Structure
Created modular library structure:
- [X] custom/lib/common.sh - output, validation, fzf prompts, filesystem selection
- [X] custom/lib/config.sh - argument parsing, config loading
- [X] custom/lib/disk.sh - partitioning, disk selection
- [X] custom/lib/zfs.sh - ZFS pool, datasets, services

**** Phase 1.4: Filesystem Selection
- [X] Added FILESYSTEM variable (zfs/btrfs)
- [X] Added select_filesystem() with fzf prompt
- [X] Btrfs selection shows "not yet implemented"
- [X] Config file supports FILESYSTEM option

**** Phase 1.5: Rename to archangel
- [X] Renamed install-archzfs → archangel
- [X] Updated build.sh references
- [X] Updated config example to archangel.conf.example
- [X] Updated script headers

*** 3. Bug Fix: set -e compatibility
Found and fixed critical bug during VM testing:
- [[ condition ]] && error pattern fails with set -e
- Fixed by converting to if/then/fi pattern

*** 4. VM Test PASSED
Full end-to-end test:
- ISO built with lib/ structure
- Unattended install completed
- ZFSBootMenu boots correctly
- Genesis snapshots created
- System fully functional
