* Session: Friday 2026-01-23 @ 11:28-13:15 CST

** Session Summary
Major session covering code review workflow creation and btrfs expansion research.

** Completed This Session

*** 1. ZFSBootMenu Merge
- Merged zfsbootmenu branch to main (fast-forward)
- ratio booted successfully with ZFSBootMenu
- ZFSBootMenu is now the default bootloader

*** 2. Code Review Workflow
- Researched code review best practices (10+ web searches)
- Studied Code Review Pyramid (Gunnar Morling)
- Created docs/project-workflows/code-review.org
  - Core Checklist: ~27 items across pyramid levels
  - Deep Dives: Security, Performance, Concurrency, Error Handling, API Compatibility, Dependencies
  - Guidance on feedback, anti-patterns, effort scaling

*** 3. Project Code Review
Conducted senior developer review of entire codebase. Found issues:
- README.org has outdated GRUB references (now uses ZFSBootMenu)
- Missing LICENSE file
- custom/archsetup-zfs is non-functional skeleton
- Stale SESSION-CONTEXT.md in root
- Makefile lint target swallows errors
- Various cleanup items

Added 14 new tasks to todo.org (Priority A/B/C).

*** 4. Makefile Target Planning
Added to todo.org:
- make deps - Install all dependencies
- make lint - Run shellcheck
- make build/test/test-quick
- make deploy - Copy to truenas + Ventoy

*** 5. Btrfs Expansion Research
Comprehensive research for multi-filesystem support:
- Created docs/research-btrfs-expansion.org
- Cloned 8 reference repos to reference-repos/

**** Key Findings
- Project rename recommendation: *archsnap*
- Btrfs RAID 5/6 is UNSTABLE - don't offer
- No native btrfs encryption - use LUKS
- Need GRUB (not systemd-boot) for bootable snapshots
- Snapshot stack: snapper + snap-pac + grub-btrfs + btrfs-assistant

**** Btrfs Subvolume Layout
- @ → /
- @home → /home
- @snapshots → /.snapshots
- @var_log → /var/log
- @var_cache → /var/cache

**** Reference Repos Cloned
grub-btrfs, easy-arch, arch-btrfs-installation, btrfs-assistant,
snap-pac, btrbk, buttermanager, alis

** Commits This Session
- c8c3502 Add code review workflow and project cleanup tasks
- e05e94d Research: Btrfs expansion and multi-filesystem support

** Files Created
- docs/project-workflows/code-review.org
- docs/research-btrfs-expansion.org

** Files Modified
- todo.org (14 new cleanup tasks + Makefile targets)

** Pending User Review
- docs/project-workflows/code-review.org (task in todo.org [#A])
- docs/research-btrfs-expansion.org

** Next Steps (When Resuming)
1. Review code-review.org document and provide feedback
2. Decide on project name (archsnap recommended)
3. Decide on btrfs implementation approach
4. Address Priority A cleanup tasks:
   - Update README.org (remove GRUB references)
   - Add LICENSE file (GPL-3.0)
   - Delete or complete archsetup-zfs skeleton
   - Add user password to install config
5. Create implementation tasks for btrfs support
6. Begin Phase 1: Refactor installer into modular structure

** Notes
- Removed Syncthing conflict file (todo.sync-conflict-*.org)
- Syncthing shutdown during session
- All changes pushed to origin/main
