pre-backup-dumps.sh: atomic_write nimmt jetzt einen optionalen
mode-Parameter (Default 0644). Damit sind alle DB-/SQLite-/BoltDB-
/Mongo-Dumps konsistent 0644 und vom Nearline-Pull lesbar. Die
sensible unraid-flash-config-Familie (.tar.gz, .sha256, .manifest)
ruft explizit mit mode 600 auf und bleibt damit Operator-only.
Loest das Permission-Problem fuer filebrowser.bolt.dump (Source
ist 0640) im naechsten regulaeren Dump-Lauf.
pull-critical-backups.ps1: Jobs koennen ExcludeFiles ueber /XF
mitliefern. borg-dumps-latest schliesst die unraid-flash-config-
Artefakte aus, weil sie bewusst 0600 bleiben sollen und sonst den
Lauf abbrechen lassen. Restore-Quelle fuer Flash-Config bleibt
das Hetzner-Borg-Repo.

node-exporter runs as nobody:65534 inside its container and was
hitting node_textfile_scrape_error 1 on homelab.prom, because the
file was 0600 root:root (mktemp default). Set it to 0644 right
before the atomic mv. Bundle inhaltsidentisch zum Git-Repo, ohne
Secrets (.gitignore-abgedeckt) und nicht sensibler als die
uebrigen /mnt/user/backups/borg/dumps/latest/*.dump-Files, die
ebenfalls 0644 sind. So funktioniert auch der Nearline-Pull-Workflow
ueber SMB (docs/H_DRIVE_NEARLINE_PULL.md).

Operational hardening across several services after live incident
analysis between 2026-05-18 and 2026-05-20:
- Gitea: disable public registration and OpenID signup/signin to
stop the external POST / 5xx bursts that triggered availability
alerts. New repo-wide policy requires every productive
Micha/homelab-infra Komodo stack to ship with an active
Gitea->Komodo webhook on the current stack ID (documented in
CLAUDE.md, AI_CONTEXT.md, WORKFLOW.md).
- posture-check: extract the Disk1 fstype check into its own
function so the documented Disk1 NTFS exception no longer raises
ntfy warnings, skip POSIX inode checks on NTFS, and dedup ntfy
alerts via a fingerprint state file with ALERT_REPEAT_SECONDS
(default 24h). Repeat-spam on the same cause now suppressed.
- docker-critical-events: parse the event JSON for container name,
action, exit code and signal; drop `die exit=0` events (clean
stops); ship a structured ntfy message instead of the raw event
line.
- Borg UI: mount /mnt/user/services into the backup container as
/local/services:ro and include homelab-infra, stacks and
posture-check in all-important-sources.txt. RESTORE_MATRIX and
DISASTER_RECOVERY updated accordingly.
- Unraid user scripts: document the new
homelab-operations-report-daily cron job and the SMTP password
file it expects on the host.
- MIGRATION_LOG: capture the four live events from this window -
Gitea 5xx burst + signup closure, Komodo webhook reconciliation,
posture-check host-version verification, Borg scope extension,
and Traefik 5xx alert detuning.
