Workers handle background tasks only (LDAP sync, email, certificate
renewal) — no user-facing traffic, so 2-of-3 redundancy isn't load-
bearing. Reduces sustained CPU by ~100m.
Server replicas unchanged at 3 (PDB minAvailable=2 — user-facing).
PgBouncer pool unchanged at 3 (DB connection pooling).
- Adopt UserLoginStage (default-authentication-login) into Terraform
and pin session_duration=weeks=4 so users stay logged in across
browser restarts. There is no Brand.session_duration in 2026.2.x;
UserLoginStage is the only correct lever.
- Cap anonymous Django sessions at 2h via
AUTHENTIK_SESSIONS__UNAUTHENTICATED_AGE on server + worker pods
(default is days=1). Bots, healthcheckers, and partial flows now
get reaped within 2h instead of accumulating for a day.
Implementation note: the env var is injected via server.env /
worker.env rather than authentik.sessions.unauthenticated_age,
because authentik.existingSecret.secretName is set, which makes the
chart skip rendering its own AUTHENTIK_* Secret. authentik.* values
are therefore inert in this stack -- this is documented in
.claude/reference/authentik-state.md so future edits use the right
surface.

- linkwarden: add Reloader match annotation to DB secret so pods
auto-restart on Vault credential rotation (was causing 100% 5xx)
- authentik: increase memory limits (server 1Gi→1.5Gi, worker 896Mi→1Gi)
to prevent OOM kills
- prometheus: drop 113k high-cardinality series to reduce HDD write rate
from ~8.8 to ~6.0 MB/s (31% reduction):
- drop all traefik/apiserver/etcd histogram bucket metrics
- drop goflow2_flow_process_nf_templates_total (9.3k series)
- drop container_tasks_state and container_memory_failures_total
- rewrite HighServiceLatency alert to use avg latency (_sum/_count)
- update cluster_health dashboard to match
- raise KubeletRuntimeOperationsLatency threshold from 30s to 60s
Phase 1 of platform stack split for parallel CI applies.
All 3 modules were fully independent (no cross-module refs).
State migrated via terraform state mv. All 3 stacks applied
with zero changes (dbaas had pre-existing ResourceQuota drift).
Woodpecker pipeline updated to run extracted stacks in parallel.
