- phase1_gitea_unraid.sh: 9-step deploy (dirs, docker-compose, app.ini, container start, wait, admin user, API token, save to .env, create org). Every step has idempotency check — running twice changes nothing. - phase1_post_check.sh: 5 independent verification checks - phase1_teardown.sh: stop container + optionally remove data, with prompts Also adds inline comments to lib/common.sh and preflight.sh explaining WHY decisions were made (SSH flags, API tmpfile pattern, port checks, etc.) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
