- port_idx now coerced to int() with 400 on invalid type (prevents string/int mismatch)
- api_network and api_links bare except blocks now log errors instead of silently passing

- C5: Validate host_ip (IPv4 check) and iface (allowlist regex) before SSH command builder
- H6: Upgrade Pulse failure logging from debug to error so operators see outages
- M6: Replace per-request O(n) purge with background daemon thread (runs every 2 min)
- M7: Background thread marks jobs stuck in 'running' > 5 min as errored

Adds comprehensive per-port link troubleshooting triggered from the
Inspector panel when a port has an LLDP-identified server counterpart.
- diagnose.py: DiagnosticsRunner with 15-section SSH command (carrier,
operstate, sysfs counters, ethtool, ethtool -i/-a/-g/-S/-m, ip link,
ip addr, ip route, dmesg, lldpctl); parsers for all sections; health
analyzer with 14 check codes (NO_CARRIER, HALF_DUPLEX, SPEED_MISMATCH,
SFP_RX_CRITICAL, CARRIER_FLAPPING, CRC_ERRORS_HIGH, LLDP_MISMATCH, etc.)
- monitor.py: PulseClient now tracks last_execution_id so callers can
link back to the raw Pulse execution URL
- app.py: POST /api/diagnose + GET /api/diagnose/<job_id> with daemon
thread background execution and 10-minute in-memory job store
- inspector.html: "Run Link Diagnostics" button (shown only when LLDP
host is resolvable); full results panel: health banner, physical layer,
SFP/DOM with power bars, NIC error counters, collapsible ethtool -S,
flow control/ring buffers, driver info, LLDP 2-col validation,
collapsible dmesg, switch port summary, "View in Pulse" link
- style.css: all .diag-* CSS classes with terminal aesthetic

- Two-service architecture: Flask web app (gandalf.service) + background
polling daemon (gandalf-monitor.service)
- Monitor polls Prometheus node_network_up for physical NIC states on all
6 hypervisors (added storage-01 at 10.10.10.11:9100)
- UniFi API monitoring for switches, APs, and gateway device status
- Ping reachability for hosts without node_exporter (pbs only now)
- Smart baseline: interfaces first seen as down are never alerted on;
only UP→DOWN regressions trigger tickets
- Cluster-wide P1 ticket when 3+ hosts have genuine simultaneous
interface regressions (guards against false positives on startup)
- Tinker Tickets integration with 24-hour hash-based deduplication
- Alert suppression: manual toggle or timed windows (30m/1h/4h/8h)
- Authelia SSO via forward-auth headers, admin group required
- Network topology: Internet → UDM-Pro → Agg Switch (10G DAC) →
PoE Switch (10G DAC) → Hosts
- MariaDB schema, suppression management UI, host/interface cards
