#+TITLE: Session Context - Interrupted Session
#+DATE: 2026-01-23
* 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- README.org has outdated GRUB references (now uses ZFSBootMenu)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
