From 398b0fe211655869a9d4ad859ff45bfb019c9796 Mon Sep 17 00:00:00 2001 From: tegwick Date: Tue, 19 May 2026 20:43:04 +0200 Subject: [PATCH] RAILIANCE-WP-0002 finished: vergabe-teilnahme T07+T08 done MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit T07 smoke: migrate all apps; /health/ 200, /ausschreibungen/dashboard/ Übersicht, /admin/login/ Anmelden, static assets (Tailwind, Alpine, htmx, Django admin) all 200. Auth-required smoke and createsuperuser deferred to the operator (interactive credentials not safe through this session); seed_dev deliberately skipped (hardcoded dev user). T08 runbook in docs/vergabe-teilnahme.md: identity, secret rotation recipes, day-to-day make targets, image promotion + rollback, troubleshooting, deferred backup posture, cross-refs. Workplan status: finished. vergabe-teilnahme is the second S5 application on railiance01 (after Gitea).
