Closes issues #6 and #15 (treated jointly, per combined analysis in their
comments). Two CronJobs, one per namespace, each pushing to its own Borg
repo on the newly booked Storage Box (u641795.your-storagebox.de:23, BX11
1TB) with its own repo passphrase - a leaked passphrase for one doesn't
expose the other:
- matrix: synapse-backup dumps the synapse + matrixauthenticationservice
DBs (shared postgres, existing chart-generated POSTGRES_ADMIN_PASSWORD)
and the Synapse media_store PVC (read-only mount)
- authentik: authentik-backup dumps the authentik DB (existing
authentik-credentials pg-password)
Custom image (rohana.axion1337.de/sorb/axion-backup:v1, postgres:17-alpine
+ borgbackup + openssh-client - matches the live Postgres major version
exactly, unlike Alpine's stock postgresql16-client) pushed as a public
package, same pattern as the existing threadnet-web image (no
imagePullSecret needed).
SSH host key pinned via known_hosts ConfigMap (captured via ssh-keyscan
ahead of time) rather than trusting on first connect in an unattended job.
Retention: 7 daily / 4 weekly / 6 monthly via borg prune. Schedule: 03:00
and 03:15, offset to avoid resource contention.
NetworkPolicy: added each backup job's pod as an allowed source to its
namespace's existing postgres ingress rule (matrix's allow-ingress-postgres,
authentik's allow-ingress-authentik-postgresql from #37). Egress already
unrestricted in both namespaces, so no change needed for the outbound SSH
connection to the Storage Box.

Almost every tracked file in the repo had drifted to mode 777 on disk
(only files created fresh this session were unaffected), and a chunk of
that drift had already been committed as spurious +x bits on plain
YAML/Markdown files (authentik.yaml, kustomization.yaml, coturn.yaml,
element-server-suite.yaml, TASKS.md, install.md, etc.) - none of these
need to be executable. Restored to 644 for regular files, 755 only for
actual scripts (postCreateCommand.sh, docker-init.sh, install-hooks.sh,
pre-commit hook, element-setup-linux.sh).
Also found element-setup-macos.command was missing +x despite having a
shebang and being meant for double-click execution on macOS - fixed.
Added .gitignore for .DS_Store and .claude/ and stopped tracking the five
.DS_Store files that had been committed by accident.

Ingress-only default-deny (egress untouched) plus explicit allows:
Traefik (kube-system) + MAS (matrix ns) -> authentik-server on 80/443,
and Traefik -> cert-manager's ACME HTTP-01 solver pods on 8089.
authentik-postgresql already has its own Bitnami-chart-managed policy,
left alone. Part of issue #10.
The matrix-invitation flow only had Invite+Prompt stage bindings, both
at order=0 (undefined order), missing the Write/Password/Login stages
entirely — invited users were never written to the DB. Applied the fix
live in-cluster (mirroring the working matrix-enrollment stage chain),
and captured it as an Authentik Blueprint (ConfigMap, mounted via
blueprints.configMaps) so the flow state is reproducible via GitOps
instead of manual admin-UI clicks.
Add Authentik v2026.x with embedded PostgreSQL in new namespace. Includes HelmRelease with valuesFrom injection for encrypted credentials, cert-manager Certificate for auth.axion1337.chat, and Traefik IngressRoute. Authentik serves as OIDC provider for MAS; registration via invitation links only.
DNS A-record setup and Authentik UI configuration (OIDC provider creation) are manual post-deployment steps.
