The hub can't reach the CPE network, so wireless signal now flows through a
new read-only F endpoint that CAN (F sits on that network + already has the
airOS code + device creds):
- services/legacy-bridge/ops_airos.php — token-gated (X-Ops-Token, same secret
as ops_reassign.php), SSRF-safe (only curls a mgmt IP present in F's `device`
table). Resolves device by serial/mac/ip, logs into the CPE (airOS >=8.5
/api/auth or <8.5 /login.cgi), reads status.cgi, returns normalized signal /
signal-AP / CCQ / TX-RX rate / airMAX capacity / model / uptime. v8 gets full
data; v6 falls back to top-level wireless.signal; CCQ clamped to 0-100.
- hub: airosSignal now calls the F bridge FIRST (OPS_LEGACY_URL host +
/app/data/ops_legacy.token), n8n webhook demoted to post-migration fallback.
Shared normalizeAiros() for both paths.
Verified end-to-end (hub -> F -> CPE): NanoBeam 5AC signal -53 / airMAX
140/143 Mbps; v6 NanoStation signal -47; offline CPE -> clean {ok:false}.
Auth reject + SSRF guard verified. docs updated (F bridge primary).
