Session 0014: Registry Naming & Backup System

Date: 2026-02-20 Status: Completed Origin: MDF Webseiten session 0019

Work Done

[x] Fixed sl-website registry placement — moved under seriousletter.services.website to resolve prefix collision
[x] Renamed all 7 Coolify services to consistent {project}-{env/purpose} lowercase naming
[x] Deleted stale stopped MDF Dev duplicate from Coolify (UUID: qw8wso0ckskccoo0kcog84c0)
[x] Fixed ops backup/restore/sync argument validation (was crashing on unbound variable)
[x] Fixed SL CLI path in registry.yaml (pointed to wrong location)
[x] Added container_name() to SL sync.py with label + prefix fallback (mirrors MDF pattern)
[x] Made ops backup <project> work without env arg (passes --all to CLI)
[x] Added backup summary to ops status — latest backup per project/env, size, age with color coding
[x] Consolidated backup dirs to /opt/data/backups/{project}/{env}/ across all projects
[x] Updated both MDF and SL CLIs for per-env backup subdirectory structure
[x] Volume consolidation: all data migrated from 10GB to 50GB volume at /opt/data
[x] Updated all path references across compose files, CLIs, systemd units, registry, ops CLI

Registry was initially ambiguous about where sl-website lived — prefix collision with other SL services caused matching bugs. Moving it under a services.website key made the prefix unique.
Per-env backup subdirs (/opt/data/backups/{project}/{env}/) are the correct structure — flat dirs were the source of orphaned files.
ops backup <project> without env should be a valid shorthand — it delegates --all to the project CLI rather than requiring explicit env arg.
Container name resolution logic must be identical across project CLIs — label-based primary, prefix fallback secondary. Divergence causes mysterious "container not found" bugs.
Old 10GB volume was kept mounted during migration to avoid cwd-in-mountpoint issues during umount.

/opt/infrastructure/servers/hetzner-vps/registry.yaml — fixed sl-website placement, naming consistency
/opt/infrastructure/ops — fixed arg validation, cmd_backup without env, backup summary in status
/opt/data/seriousletter/{dev,int,prod}/code/scripts/sync/sync.py — added container_name() with fallback
Code/mdf-system/scripts/sync/sync.py — per-env backup subdirectory paths
All compose files, systemd units — /opt/data2 → /opt/data path updates
