# Regenerates docs/SCRIPTS.md from the repo state. Produces:
#   1. Header + status legend + regen instructions.
#   2. Table of every nomarchy-* script (location, callers, status).
#   3. Table of every menu entry in features/scripts/utils/nomarchy-menu
#      (submenu, label, target command, status).
#   4. Snapshot list of orphaned references (called somewhere, no script).
#
# Status heuristic in Phase A:
#   kept     — file exists AND is called from at least one *.nix / *.conf /
#              shell file outside its own directory.
#   unused?  — file exists but no caller found. Phase B decides delete-dead
#              vs intentional public API.
#   missing  — referenced but no file. Phase B decides port-from-omarchy
#              vs delete-dead vs stub-with-notify.

# Nomarchy Script & Menu Audit

Auto-generated table for [Pillar 3 of the roadmap](ROADMAP.md#3-pillar-script--menu-audit).
**Do not edit by hand.** Regenerate after script or menu changes:

```bash
./bin/utils/nomarchy-docs-scripts --out docs/SCRIPTS.md
```

The status column uses a Phase A heuristic — `kept` / `unused?` / `missing`.
Phase B (per-batch PRs) refines those into `port-from-omarchy`,
`delete-dead`, or `stub-with-notify` and updates the rows.

## Status legend

- `kept` — script exists and is called from somewhere outside its own directory.
- `unused?` — script exists but no caller was found. Could be dead, could be
  intentional public API. Phase B triage decides.
- `missing` — referenced from code but no script file exists. Phase B triage
  decides whether to port from Omarchy upstream, delete the caller, or stub
  with `notify-send`.
- `port-from-omarchy` — Phase B verdict: lift the upstream Omarchy script,
  rewrite for NixOS paths.
- `delete-dead` — Phase B verdict: remove and update callers.
- `stub-with-notify` — Phase B verdict: temporary `notify-send` stub.
