Keep the graceful final-ACK TCP close and optional FEM control guards from
pixitha's browser compatibility fixes. Replace Brotli negotiation and duplicate
page assets with one gzip representation compressed by Google Zopfli 0.4.3
using 1,000 iterations. Compress the bootstrap, captive success, compact OTA,
and static WiFi setup pages with the same validated build cache.
Honor gzip quality values and wildcard precedence. Validate compressed OTA
page evidence in the firmware capability gate, and add native and Python
regressions plus CI coverage. Remove the unused Brotli build dependency.
Validation: 54 native tests, 56 Python/browser checks, full V4.3 build and
verified application flash. Actual V4 WiFi responses matched the generated
gzip assets; 30 repeat downloads completed without reboot. Chromium loaded
the setup and settings pages without script or transfer errors. Physical
Android testing is pending because the Pi detects no phone over USB or mDNS.
Use a bounded timed OTA forwarding cache while preserving echo, queue, TempRadio and forwarding-policy guards. Add opt-in manifest recovery for directly reachable legacy relays and interactive 125 kHz SF5/SF6/SF7 rehearsals, with regression tests and documentation.
Accept preamble-bearing TempRadio status from newer firmware while retaining legacy replies. Keep the 20-minute hard minimum but make the 120-minute and timeout estimates advisory, with a window-only override. Add parser, rehearsal, relay identity, and RAK bootloader regression coverage.
Integrate compatible observer board, preset, WebConfig, display, CI, and policy updates. Preserve the checkout's newer MQTT binary preferences and WiFi bridge runtime where the forked implementations conflict. Keep ThinkNode observer networking WiFi-based until the Ethernet transport is wired into that runtime.
