From 563b0d46653dfc48e1caced2e8bfa47229cb8114 Mon Sep 17 00:00:00 2001 From: Matt Edholm Date: Wed, 22 Apr 2026 22:41:05 -0400 Subject: [PATCH] Implement story 1.3: WiFi hotspot and captive portal form Implement wifi.py (start_ap/stop_ap/kill_wifi with subprocess and ProvisioningError), portal.py (Flask captive portal with Android/iOS/Windows probe redirects and 404 catch-all), updated provision.py provisioning loop, and full test suite (38 passing).
