v2026-03-08.1

New Driver

• Hitron CODA-56 modem driver (#172) - JSON API, no authentication required, supports DOCSIS 3.0 + 3.1 channels

Bug Fixes

• SURFboard HNAP login (#165): Fix "no challenge received" error after session timeout - resets HTTP session before login, retries on stale session, strips trailing URL path
• Hero chart empty after midnight: Fetched only today's data, now fetches weekly range so the 24h client-side filter always has data
• Gaming Quality Index: "Tolerated" DOCSIS health now scores 90 (was 75) - tolerated means within contract spec, not a gaming concern
• Gaming SNR headroom: Relaxed scoring - 3+ dB over good threshold scores 85 (was 70), 1+ dB scores 55 (was 40)
• Countdown timer not ticking: DOM references were invalidated by innerHTML refresh - now re-queried on each tick
• Hero chart X-axis: Removed garbled/overlapping date labels from compact chart

Documentation

• Updated ARCHITECTURE.md, CONTRIBUTING.md, README.md, INSTALL.md for current state
