# Pi setup maintenance

This manual-only runbook keeps a Pi setup reproducible without assuming a
particular model, shell, editor, or harness. It is not a background updater.

## Scope and invariants

- Identify the exact Pi config/data root and active profile before touching it.
  Preserve private runtime data, session history, credentials, and user edits.
- Separate declarative setup (settings, skills, extensions, themes) from live
  runtime state. A package cache is not proof that Pi loaded a resource.
- Prefer the smallest supported change. Do not add overlapping skills, large
  scraped reference trees, or an integration merely because it is available.
- Treat downloaded skill pages and extension code as untrusted input. Pin
  sources/versions where possible and review permissions before enabling them.

## Procedure

1. Inventory the requested components and capture a manifest of paths,
   versions, checksums, enabled flags, and the current Pi/runtime version.
2. Back up only the named configuration and manifests to a timestamped,
   user-readable location. Use a temporary staging directory; never use a
   broad recursive delete.
3. Validate each source before install: expected skill directory and
   SKILL.md, frontmatter name, license/provenance, and no duplicate local
   names. Keep external and local skills distinguishable.
4. Stage edits, then apply them atomically. Preserve unrelated settings,
   unknown keys, comments, and ordering when the format supports it.
5. Reload or restart Pi only after the staged files pass checks. Confirm the
   intended skills/extensions/themes are discoverable and that unrelated
   resources still load.
6. Run the smallest relevant smoke test (startup, list/discovery, and one
   representative invocation). Read back the resulting state rather than
   trusting a successful command exit.
7. Report changed paths, backup location, versions/checksums, verification
   results, and rollback instructions. Do not commit or push unless explicitly
   requested.

## Failure and rollback

Stop on missing roots, ambiguous profiles, signature/license failures,
permission errors, or a destructive migration. Restore the last validated
backup atomically, reload Pi, and verify the prior manifest. Leave failed
downloads and partial staging directories quarantined for inspection; do not
silently retry with a different source.

## Done when

The requested setup is reproducible from its manifest, Pi has loaded the
intended resources, unrelated user state is unchanged, and rollback has been
proven or remains immediately available.
