- 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).
Coverage rasters were being written to priv/static/coverage on the pod's
ephemeral filesystem — fine on a single-pod dev box, broken under k8s
where pods share NFS at /data and a restart wipes computed predictions.
* New :coverage_storage_dir config (defaults to priv/static/coverage for
dev/test, "/data/coverage" in production).
* Raster.output_dir/absolute_raster_path read this config and resolve
{otp_app, rel} or absolute paths.
* Endpoint now mounts a dedicated Plug.Static at /coverage from that
same config — replicas all serve the same NFS-backed file regardless
of which one ran the compute.
* Drop "coverage" from static_paths/0 since the dedicated plug owns
that prefix now.
Add logger filter to drop Kubernetes health probe logs that were flooding
production logs every few seconds.
Implementation:
- Create ToweropsWeb.TelemetryFilter module with filter_health_checks/2
- Configure as logger :default_handler filter in prod.exs
- Filters based on request_path metadata and message content
- Drops logs for GET /health and HEAD / requests
Impact:
- Eliminates ~120 log entries per minute per pod from K8s probes
- Keeps application logs focused on actual user activity and errors
- No impact on health check functionality - only suppresses logging
Files:
- lib/towerops_web/telemetry_filter.ex (new)
- lib/towerops/application.ex (attach filter on startup)
- config/prod.exs (add filter to logger config)
- CHANGELOG.txt
Add logger filter to drop repetitive 'Cannot find module' errors
from net-snmp library. These errors occur when snmptranslate can't
find vendor-specific MIB modules but don't affect functionality
since the system falls back to numeric OIDs.
The errors were flooding production logs (hundreds of identical
messages) during polling of Morningstar devices that reference
TRISTAR MIB modules.
Changes:
- Add drop_snmp_mib_errors/2 filter to LoggerFilters module
- Register filter in production logger configuration
- Filter matches exact error format from snmptranslate stderr
The root cause (missing NIF binary) will be addressed separately
by compiling the towerops_nif.so during Docker build.

The plug was incorrectly placed in the endpoint, causing it to run on
all requests including APIs. Moved to :browser pipeline where it belongs,
and removed redundant fetch_session call since the pipeline handles it.
When Kubernetes performs rolling deployments, the old pod gracefully shuts down
and Oban's internal processes receive EXIT :shutdown signals. These are logged
as "unexpected" even though they're normal during shutdown.
Added custom logger filter to drop these messages in production:
- Oban.Queue.Watchman/Producer receiving EXIT :shutdown
- Oban plugin processes receiving EXIT :shutdown
- Reduces log noise during deployments without hiding real errors
The filter is production-only to preserve full debugging in development.
