Session 0025: Dashboard Bugs and SL Routing Fixes

Date: 2026-02-24 Status: Completed Origin: MDF Webseiten session 0048 (Part 2 only — DNS cutover and mail recovery sections skipped)

Work Done

[x] Removed "Recreate" lifecycle action (redundant with Rebuild for bind-mount projects)
[x] Added Backup button (blue): opens lifecycle modal with SSE streaming to /api/backups/stream/{project}/{env}
[x] Added Restore button (purple): navigates to Backups page at drill level 2 for that project/env
[x] Added cache invalidation on backup success

[x] Diagnosed root cause: SL containers only on seriousletter-network, not on proxy network Traefik uses
[x] Permanent fix: added proxy network to docker-compose.yaml for all 3 SL envs (prod/int/dev)
- backend and frontend services get proxy in networks list
- proxy: external: true added to networks section
[x] Added health checks for both services:
- Backend: python3 urllib.request.urlopen("http://localhost:8000/docs")
- Frontend: wget --spider -q http://127.0.0.1:3000/ (explicit 127.0.0.1, not localhost — Alpine resolves to IPv6 ::1)

[x] Fixed sync section only showing MDF (not SeriousLetter)
[x] Root cause (two-part):
1. registry.py had desc.sync.get("type") == "cli" — SL had sync.type: toolkit, evaluated to False
2. SL's toolkit type was itself wrong — should be cli with a CLI path
[x] Fix in registry.py: "has_cli": desc.sync.get("type") == "cli" → "has_cli": bool(desc.sync.get("type"))
[x] Fix in /opt/data/seriousletter/project.yaml: sync.type: toolkit → type: cli with cli: path

[x] Fixed overview card showing stale "INT Latest" date while drill-down showed correct newer backups
[x] Root cause: string comparison between incompatible date formats:
- Compact (MDF CLI): 20260220_195300
- ISO (toolkit): 2026-02-24T03:00:42
- Character '0' > '-' meant compact dates always "won" the > comparison
[x] Fix: added normalizeBackupDate() function to convert all dates to ISO format at merge time in mergeBackups()

When adding a container to a new network, an ad-hoc docker network connect is lost on restart — the fix must go in the compose file
Alpine localhost resolves to ::1 (IPv6). Services binding only IPv4 0.0.0.0 won't respond. Use 127.0.0.1 explicitly in health checks.
For has_cli logic: any truthy sync.type value means the project has ops CLI support — don't compare to a specific string
Date normalization must happen at merge time, not display time, to get correct max() comparisons

static/js/app.js — removed recreate modal/handler, added backup modal, URL routing for restore button, cache invalidation, normalizeBackupDate() + mergeBackups() fix
app/routers/registry.py — has_cli logic fix
/opt/data/seriousletter/project.yaml — sync.type corrected
/opt/data/seriousletter/{prod,int,dev}/code/docker-compose.yaml — proxy network + health checks
