Guard that nomarchy-install share/template ships byte-identical flake.nix/system.nix/home.nix/theme-state.json to templates/downstream (the single machine-seed SoT; default.nix copy list). - tools/check-template-sot.py — share vs SoT file-set + content - checks.template-sot — pure python + package path (theme-contrast pattern) - BACKLOG #72 removed; JOURNAL entry Verified (V0): python3 tools/check-template-sot.py <share/template> templates/downstream nix build .#checks.x86_64-linux.template-sot

"""Installer ↔ templates/downstream SoT parity (flake check `template-sot`).
|
|
|
|
Usage:
|
|
check-template-sot.py <install-share-template> <templates/downstream>
|
|
|
|
Asserts the files nomarchy-install ships under
|
|
$out/share/nomarchy-install/template/ are byte-identical to the same
|
|
names in templates/downstream — the single source of truth for machine
|
|
flake seed files (see pkgs/nomarchy-install/default.nix installPhase).
|
|
|
|
The package copies a fixed file list (not a recursive tree copy):
|
|
|
|
flake.nix system.nix home.nix theme-state.json
|
|
|
|
README.md and hardware-configuration.nix stay repo-only (docs /
|
|
nixos-generate-config at install time) and are intentionally absent
|
|
from the share.
|
|
|
|
Wired as `checks.template-sot` in flake.nix; also runnable after a local
|
|
package build:
|
|
|
|
share=$(nix build --no-link --print-out-paths .#nomarchy-install)
|
|
python3 tools/check-template-sot.py \
|
|
"$share/share/nomarchy-install/template" templates/downstream
