Add bounded compact page rendering, serialized Link and Resource lifecycle handling, TCP reconnect corrections, and deterministic Python RNS conformance coverage.
Physically verified anonymous index retrieval and rendering on T-Deck. Same-destination Link reuse and italic rendering remain follow-up fixes.
Confirmed fixes:
- LVGL hybrid-allocator threshold 1024->256 (lib/lv_mem_hybrid.h): moves ~45KB of
small LVGL objects to PSRAM, fixing internal-heap starvation that made the
call/loopback pipeline intermittently fail to allocate and reboot mid-call
(internal free 71->116KB, largest contiguous block 61->106KB).
- ES7210 mic PGA gain 21dB->12dB (lxst_audio.cpp): 21dB saturated the ADC -- an
rms-7003 noise floor in silence + 0x8000 negative-rail spikes + a spectral-peak
shift that masqueraded as a "+17% pitch warp". At 12dB idle silence is clean (rms 48).
Diagnostic harness (PYXIS_TEST_HOOKS, test-only): T:RAWMIC[stage], T:REG, and
T:RECORD/T:DUMPREC add a raw-mic UDP tap plus a reliable PSRAM recorder with a
checksummed serial transfer, and T:LOOPBACK wiring, for objective mic-capture
analysis (offboard Whisper STT scoring).
Exploratory / still unresolved: captured speech remains garbled (oscillating static,
likely an ES7210 sigma-delta capture instability -- under investigation). Includes a
16kHz/main-PLL clock path + MICBIAS exploration; the "warp" was the gain artifact, not
a clock issue, so the 16kHz path can later be simplified back to 8kHz.

Settings/clock (user-reported):
- Announce interval: default 1h (was 60s); the field is now MINUTES (label
"Announce Interval (min):", populate /60, read *60).
- Prop sync interval: default 4h (was 1h); the field is now HOURS (label
"Prop Sync Interval (hrs):", populate /3600, read *3600); log prints hours.
- Settings clock now ticks live: SettingsScreen::tick() (throttled ~1s) is hooked
into UIManager::update() like the announce-list tick, so the Time/GPS/system
readouts refresh while the screen is open instead of being a static snapshot.
OTA repair (was broken two ways; diagnosed via an ultracode workflow):
- patch_nimble.py hardcoded the `tdeck` libdeps path, so building any OTHER env
(tdeck-ota gets its own libdeps tree) never received the NimBLE patch that
DEFINES nimble_host_reset_reason -> undefined-reference link error. Made it
env-aware (env.get("PIOENV",...)), matching the four sibling pre-scripts. Also
restores 3 NimBLE stability patches that were silently missing from OTA builds.
- ArduinoOTA onStart synchronously called TCPClientInterface::stop() (blocks up to
30s), overrunning espota's ~10s connect-back window -> "No response from device"
(phase 2), and its un-fed watchdog tripped reboots. Made onStart non-blocking.
- [env:tdeck-ota] upload_command invoked a non-existent tools/espota.py -> switched
to upload_protocol=espota.
- Do NOT WiFi.setSleep(false): the ESP32 requires WiFi modem-sleep when WiFi+BT
coexist (aborts at boot otherwise) -- documented inline.
Verified on device: tdeck-ota links; OTA over WiFi completes 100% (Result: OK) and
the device reboots clean.
