The staff Assistant reported "signal non mesurable à distance" for fibre modems
because check_service only reads passive status (TR-069 + local SNMP poller),
which has no signal for tech-3 XGS-PON ONUs (olt3/172.17.x). F gets it live via
the n8n dostuff GET — the assistant just never called it.
New read tool check_signal (parity with F's live "get"):
- fibre: dostuffStatus (n8n, OLT live → Rx/Tx dBm, distance, uptime, VoIP/IPTV/
WAN/firmware); tech-2 fallback to olt-snmp getOnuBySerial.
- sans-fil (airOS): airosSignal via the F bridge (signal/signal-AP/CCQ/TX-RX
rate/airMAX capacity).
- resolves the customer's equipment from Service Equipment (prefers ONU w/ olt_ip,
else CPE w/ ip_address). Quality advice (fibre Rx thresholds, airOS dBm).
- check_service now points at check_signal when signal is null; system prompt
forbids concluding "non mesurable" without calling check_signal first.
Verified live on the reported case (Frédérick Séguin C-710816574555903 →
TPLGA1E7FA90 @ OLT 172.17.0.7): Rx -16.74 / Tx -11.77 dBm, "bon", distance 2024 m.
