Thore Cimbal 32e2c8e556 feat: deploy client-side ClamAV scan service for encrypted rooms
Auto-Deploy on Push / verify-and-notify (push) Successful in 53s
Synapse's own media-scanning module (Issue #19) can never see E2EE
attachment content - a structural limit, not a bug. This adds a small
standalone HTTP wrapper around the same ClamAV instance, reachable
from browser JS at /_scan, so the ThreadNet-Web client fork can scan
plaintext both before encrypting/uploading and after downloading/
decrypting - covering both directions regardless of room encryption.
Auth via Synapse's own /whoami endpoint, no separate auth system.

Thore Cimbal db77785b6b feat: real media antivirus scanning via custom Synapse module (Issue #19)
Auto-Deploy on Push / verify-and-notify (push) Canceled after 0s
Deploys ClamAV and a small stdlib-only Synapse spam-checker module
implementing check_media_file_for_spam over clamd's INSTREAM protocol.
Unlike the originally-considered matrix-content-scanner proxy (which
needs client-side cooperation neither Element Web nor Element X
provide), this hooks Synapse's own module API directly - transparent
to every client for unencrypted media. No custom Synapse image needed:
the module is mounted via a ConfigMap onto PYTHONPATH using the ESS
chart's extraVolumes/extraVolumeMounts/extraEnv support. Fails open on
scanner errors so a ClamAV outage can't block all uploads.

Thore Cimbal 7f42a456eb feat: deploy Draupnir moderation bot (Issue #18)
Auto-Deploy on Push / verify-and-notify (push) Canceled after 0s
Bot account registered via mas-cli, compatibility token issued and
stored via sops. Adds an explicit NetworkPolicy allow-rule since
Draupnir needs to reach Synapse's client-server API in-namespace,
which the existing default-deny policy would otherwise silently block.

Thore CimbalandClaude Sonnet 5 f5e9fc5d2b feat(backup): add nightly Borg backups to Hetzner Storage Box
Auto-Deploy on Push / verify-and-notify (push) Canceled after 0s
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.

Thore Cimbal 703cf1ff1c fix: Allow synapse-main to reach MAS's port 8080 for token introspection
Auto-Deploy on Push / verify-and-notify (push) Canceled after 0s
Second port-config incident from this rollout: synapse calls MAS's
oauth2/introspect endpoint on port 8080 (not 8081 as assumed) for
every single authenticated request (sync, pushrules, capabilities,
etc). The rule only allowed kube-system (Traefik) on 8080, so every
authenticated API call failed with 503 "Unable to introspect the
access token" - all clients showed a lost connection. Patched live
immediately, this commit brings Git back in sync with that patch.

Thore Cimbal 30578abaaf feat: Default-deny ingress NetworkPolicy for matrix namespace
Auto-Deploy on Push / verify-and-notify (push) Canceled after 0s
Ingress-only default-deny plus per-component allow rules, using named
container ports throughout (not Service ports) after the authentik
port-mismatch incident. Traefik -> element-web/element-admin/haproxy
(fronts both matrix.axion1337.chat and well-known)/MAS; synapse <-
haproxy+MAS; postgres <- synapse+MAS; RTC signalling via Traefik, RTC
media NodePorts left open to the internet by design; monitoring scrape
allows for synapse/postgres/rtc-sfu metrics; ACME solver allow. coturn
(hostNetwork) needs nothing - NetworkPolicy doesn't apply to it. Part
of issue #10.
