Re-diagnosis of the "btrfs-assistant 2.2 segfaults on launch" bug, and
the fix is not the planned nixpkgs override:
1. gdb: the crash is btrfs_util_subvolume_iterator_next() —
libbtrfsutil's UNPRIVILEGED subvolume-iteration path in btrfs-progs
6.17.1 (upstream-fixed after 6.17.1, kdave/btrfs-progs 886571653).
Symbol versions were checked and match: not ABI/link drift.
2. VM A/B on real btrfs: as root it works (exit 0); as a user it
segfaults (139). The pkexec launcher runs it as root — so the GUI
path was fine all along, except…
3. …the distro shipped NO polkit authentication agent: every pkexec
prompt in the session failed silently. That is the actual root
cause of "the GUI doesn't open".
Shipped: hyprpolkitagent (Hyprland's Qt agent — the prompt is
Stylix-themed) via exec-once in hyprland.nix; `nomarchy-menu snapshot`
prefers btrfs-assistant-launcher again, with the nomarchy-snapshots
fzf flow kept as fallback (and for SSH); checks.snapshot-gui guards
the root path + offscreen GUI event loop on a real btrfs volume so a
lock bump can't silently regress it. No btrfs-progs patch: all our
flows are root-side; the unprivileged fix arrives with a lock bump.
Verified: V0 (flake check) + V2 (snapshot-gui check, executed green) +
V1 (HM generation builds; hyprland.conf carries the agent exec-once;
generated menu passes bash -n with the launcher wiring). Remaining V3
queued: first on-hardware themed polkit prompt.

settings.autoCommit — toggled from System › Auto-commit (self-gated on
the flake being a git repo) — makes every nomarchy-theme-sync apply/set
also git-commit theme-state.json in the downstream flake, so settings
history is `git log`. Off by default.
Design: the flag is live-read by the tool on each write (nothing in Nix
consumes it → instant toggle, no rebuild, no new option); the commit is
pathspec-limited to theme-state.json so unrelated dirty files are never
swept up; it fires when the flag is on before OR after the write, so
the disable-toggle itself lands in history; same-value writes no-op
(diff against HEAD); missing git identity falls back to
Nomarchy <nomarchy@localhost>; `bg next` is deliberately excluded.
Rider fix: `get` now prints booleans JSON-style (true, not Python's
True) — un-sticking the System menu's "Auto timezone (on/off)" label,
whose `= true` comparison could never match. All shell consumers
already normalise true|True, so no other behavior change.
Verified: V0 (py_compile, nix flake check) + V1 (HM generation builds,
generated nomarchy-menu passes bash -n, wiring present in the rendered
script) + a 7-assertion sandbox-repo round-trip covering enable/set/
same-value/disable/post-disable/apply paths and the identity fallback.
Remaining: on-machine check queued in agent/HARDWARE-QUEUE.md.

A git-tracked agent/ directory so AI agents can iterate on the distro
unattended (runner-agnostic: /loop, headless claude -p, or a fresh
manual session — all state lives in the checkout, per the distro's own
philosophy):
- LOOP.md — the iteration protocol: orient → pick one BACKLOG task →
verify up the V0–V3 ladder → commit+push main → record. Safety rails
(v1 untouchable, no force-push, no surprise lock bumps) and
stop-and-escalate conditions.
- BACKLOG.md — the forward half of docs/ROADMAP.md reworked into a
prioritized queue (5 NOW / 6 NEXT / LATER / PROPOSED / Decisions);
ROADMAP.md stays the design/decision record + shipped log.
- GOALS.md — the four pillars (stable > reproducible/zero-hidden-state >
effortless config > beautiful), quality bars, non-goals.
- CONVENTIONS.md — coding/design rules (in-flake state, menu placement,
Waybar whole-swap parity, toggle-vs-package, no formatter).
- MEMORY.md — curated hard-won lessons (VM recipes, btrfs-assistant
segfault watch, rofi/WirePlumber/hyprlock gotchas).
- HARDWARE-QUEUE.md — every pending V3 on-hardware check collected from
the ROADMAP, with exact steps, split by machine.
- JOURNAL.md — append-only iteration log, seeded with this bootstrap.
Plus a root CLAUDE.md entry point and README/ROADMAP pointers.
Verified: V0 — docs-only; nix flake check --no-build green.
