Two dishonesty directions, one rule (plan 75 §A3/A4): a probe answers a
value or None, never 0 when undetermined — and a real 0 must survive.
Live paths normalized every missing reading to 0 while the history path
stored NULL for the same probe: agent counters an LXC agent can't
determine rendered as a perfectly idle box; load average on unsupported
platforms read 0.00 (and silenced the load alert); CPU freq read 0 MHz;
an empty history window summarized as '0.0 avg'. The mobile summary
called a method that does not exist and rendered 0/0/0 permanently.
One unavailable network counter raised uncaught and froze the entire
live broadcast.
Reverse direction: falsy traps (x if x else None) collapsed a genuinely
idle 0.0 into 'no data' in rollups, averages, and the history model.
Fleet: KPI tiles read '0.0 ms latency' / '100% success' with no data;
never-probed servers exported serverkit_server_up 0 to external
alertmanagers — the up-series now emits only for determined
connectivity. get_all_metrics is per-section fault-tolerant so one
failed probe can't blank the other six.
Enforce admin and workspace permissions, improve logging, and add DNS frontend/API support.
- Backend: added admin checks to cloud_provisioning and marketplace endpoints; added require_workspace_access helper and applied to multiple workspace endpoints to enforce membership/admin access; persist push subscription data in mobile API (commit to DB); replaced print() debugging with structured logger calls across agent_registry and added logging/exception handling in monitoring_service.
- Frontend: added a DNS API client (frontend/src/services/api/dns.js) and registered it in the API index; extended DNSZones UI to collect provider zone ID and API token, updated create payload and form reset; added optional modal footer prop to Modal component; moved rollup native binding to optionalDependencies in package.json.
- Misc: added '*.png' to .gitignore and a minor spacing change in install.sh.
These changes improve security checks, observability, and add DNS management features in the UI/API.
Phase 37: Progressive Web App manifest, service worker for offline caching,
push notification registration, quick actions API, mobile summary endpoint,
and offline data caching for server status.
