Some checks failed
Check / eval (push) Has been cancelled
The machine flake's git-tracked settings file is system state, not "theme" only — rename it to state.json. CLI becomes nomarchy-state-sync with a nomarchy-theme-sync symlink for scripts and muscle memory. Eval (mkFlake, doctor, lifecycle) still accepts theme-state.json; the next write migrates to state.json and removes the legacy file. Documented in MIGRATION.md; drop the CLI alias after release notes.

# Auto time-of-day theme switch (BACKLOG #79, VISION § D). A user timer
|
|
# periodically runs `nomarchy-state-sync auto`, which reads
|
|
# settings.autoTheme = { enable, day, night, sunrise, sunset } from the
|
|
# state file and applies the day or night preset for the current clock —
|
|
# through the SAME one engine as a manual `apply` (no second pipeline).
|
|
#
|
|
# The command self-gates (no-op when disabled) and is idempotent (it only
|
|
# rebuilds when the active theme actually needs to change), so the timer
|
|
# can tick freely. Install is gated on the state flag (like nomarchy.updates
|
|
# gates on its enable), so a machine not using the feature carries no timer;
|
|
# enabling it from the menu (slice 3) writes the flag + rebuilds, which is
|
|
# what brings the timer into being.
