Nearby boards passively scan and build a market view of competing TollGates without requiring internet access. Features: - beacon_price.c/h: 26-byte packed Vendor IE payload (price, step, metric, mint_hash, geohash, npub_hash), injected via esp_wifi_set_vendor_ie() - market.c/h: Passive WiFi scan receiver, vendor IE callback parsing, BSSID-correlated market entries, effective price ranking - GET /market API endpoint: JSON market snapshot with discovered entries - AP-only services: beacon + market + API start on WIFI_EVENT_AP_START, independent of STA connectivity - STA reconnect fix: 2s delay between retries creates scan windows; s_sta_connecting guard prevents double-connect - write-config-ap-only-a/b Makefile targets for STA-less testing - market_tick() in main loop, client price comparison logging Hardware verified: both boards discover each other via Vendor IE beacons. Board A sees TollGate-C0E9CA (RSSI=-30), Board B sees TollGate-B96D80 (RSSI=-25). test-market.mjs: 9/9, test-price-discovery.mjs: 7/7 per board. Unit tests: 45 new assertions across test_beacon_price (28) and test_market (17). All 15 test suites pass.
