Prod paired the Oban Pro Smart engine + unique workers with core
Oban.Plugins.Lifeline, whose rescue has no unique_violation handling. An
orphaned executing CheckExecutorWorker job rescued back to available collides
with its already-scheduled successor on oban_jobs_unique_index (23505),
crashing the plugin every 60s and leaving ~150 orphans stuck. Switch prod to
Oban.Pro.Plugins.DynamicLifeline, which repairs the conflict via
Smart.clear_uniq_violation. Dev keeps core Lifeline (Basic engine).
Add a shallow /health/live endpoint that does not touch db/redis. k8s liveness
and startup probes now target it so a transient dependency outage can't kill or
block boot of a healthy pod; readiness keeps the deep /health to gate the load
balancer. (deployment.yaml probe/replica change pushed separately, after the
image carrying /health/live is live.)
Also drop unused POSTGRES_* keys from the secrets example.
- H12: session and remember-me cookies get http_only + secure (prod-only).
Cookie can no longer be read via document.cookie (XSS exfil defense)
and the Secure flag is set in production via config/prod.exs.
- L2: 404 tracker uses EXPIRE … NX so a sustained probe can't keep
refreshing the 60s window and dodge the threshold ban.
- L5: vault only reads CLOAK_KEY when :env == :prod — a developer with
a prod env var set in their shell won't accidentally encrypt local
data with the production key.
- L6: health endpoint no longer leaks the app version.
- L8: Preseem.dismiss_insight/2 + InsightsLive uses it — dismissing now
requires the insight to belong to the user's org (closes IDOR).
- L10: SidebarCollapse JS hook stores its click handler and removes it
in destroyed(); listeners no longer accumulate across LV navigation.
- L11: WebMCP navigate tool rejects anything that isn't a same-origin
absolute path (blocks javascript:, data:, off-site URLs).
Performance:
- HealthController: honor `:timeout` from `:redis` config (was hardcoded
2s) so the 503-when-unreachable test exits immediately
- DevicePollerBranches: drop `collect_events` window 1500ms → 100ms
(PubSub broadcasts are synchronous from `run_perform`)
- Towerops.Unused: cache xref analysis in `:persistent_term` keyed by
BEAM mtimes so repeated `mix unused` invocations skip re-analysis
- DiscoveryWorker: make wait_loop interval configurable via
`:discovery_wait_interval_ms` (25ms in tests vs 500ms in prod)
- ProfileWatcher: configurable `:profile_reloader` so tests can stub
the YAML reload instead of paying the full disk-load cost
- PingExecutor: tag the loopback test `:network` (it shells out to
`ping`); coverage already provided by 4 other `:network`-tagged tests
Flake fix:
- FrequencyChange tests used hardcoded `~U[2026-05-09 12:00:00Z]`,
which now falls outside the rule's 24h lookback window. Switched to
`DateTime.utc_now()` so scans stay inside the window regardless of
clock progression.
Added logging to identify which component is failing health checks:
- Log database and Redis status on each health check
- Log Redis errors with full error details
- This will help diagnose the production 503 errors
Create HealthController that returns 200 OK for health checks.
