+## Dev environment tips
+
+- use treefmt to format all files
+- make python code ruff compliant
+- use pytest to test python code
+- always use the minimum amount of complexity
+- if judgment calls are easy to reverse make them. if not ask me first
+- Match existing code style.
+- Use builtin helpers getenv() over os.environ.get.
+- Prefer single-purpose functions over “do everything” helpers.
+- Avoid compatibility branches like PG_USER and POSTGRESQL_URL unless requested.
+- Keep helpers only if reused or they simplify the code otherwise inline.

-# ZFS failed root import recovery
-
-## Fast path
-
-If the machine fails to boot because ZFS refuses to import `root_pool`:
-
-### GRUB
-
-1. At the bootloader menu, select the normal NixOS entry.
-2. Press `e`.
-3. Find the line that starts with `linux`.
-4. Append this to the end of that line:
-
-```text
-zfs_force=1
-```
-
-5. Boot once with `Ctrl+x` or `F10`.
-
-### systemd-boot
-
-1. At the bootloader menu, highlight the normal NixOS entry.
-2. Press `e`.
-3. Append this to the end of the options line:
-
-```text
-zfs_force=1
-```
-
-4. Press `Enter` to boot once.
-
-## After boot
-
-Run:
-
-```bash
-sudo zpool status
-sudo zpool import
-journalctl -b | rg "ZFS|zfs|import|root_pool"
-```
-
-## Expected result
-
-`sudo zpool status` should show `root_pool` as `ONLINE`.
-
-## Reboot test
-
-Run:
-
-```bash
-sudo reboot
-```
-
-Do not add `zfs_force=1` the second time.
-
-## If it still fails
-
-Boot once more with:
-
-```text
-zfs_force=1
-```
-
-Then run:
-
-```bash
-sudo zpool status -v
-sudo zpool history | tail -n 50
-journalctl -b | rg "ZFS|zfs|import|root_pool"
-```
-
-## Notes
-
-- Root pool name is `root_pool`.
-- This is a one-time recovery path after disk moves, controller changes, dirty exports, or interrupted imports.
-- Some hosts also need the LUKS unlock USB key inserted before boot.
