1// nx_iot_research_fetch.nx -- SOVEREIGN multi-source web-fetch to RESEARCH how others do SMART-HOME IoT
2// PAIRING + UNIFICATION (operator 2026-06-22: "use the nishi researcher and see how others do this" --
3// pair unpaired bulbs + unify the home IoT onto our hub, S-class). Mirrors the proven
4// nx_idam_research_fetch / nx_docpub_research_fetch pattern: own TLS-1.3 (nx_https_fetch_follow) + the
5// Mozilla CA store, saves each source to knowledge/fetched/iot_*.raw so research COMPOUNDS to the Library
6// and can be grepped to CITE (>=2-source no-hearsay). 100% sovereign (own TLS, nx_cc->nxasm, no curl/wget/gcc).
7// Idempotent have-skip (also the per-fetch mmap-leak workaround; re-run fills gaps).
8// Axes = what "pair the bulbs + unify to a sovereign hub, S-class" must learn from the field:
9// (A) WIFI PROVISIONING / ONBOARDING (how an unpaired device joins a network: WPS, Wi-Fi Easy Connect/DPP,
10// captive-portal SoftAP, the access-point pairing dance)
11// (B) DISCOVERY + LOCAL CONTROL (cloud-free hub<->device: mDNS/DNS-SD, MQTT, CoAP -- the LAN floor)
12// (C) HUBS + UNIFY STANDARDS (how others unify: Home Assistant, openHAB, Matter, Thread, Zigbee)
13// (D) NETWORK ISOLATION / IoT SECURITY (the S-class IoT-SSID/VLAN segmentation pattern)
14// (E) VENDOR / ECOSYSTEM (TP-Link et al. -- the real fleet)
15// expect_exit: 0 license_tier: ORIGINAL
