Keep selected chats bound to full contact keys and route keyboard channel sends through the active transport. Deliver accepted plain, room and Meshtext messages to local history and notifications once; disarm rejected sends and retries.
Use shared live radio settings, GPS acquisition and power-saving policy, screen timers and red night palette. Report save failures, preserve verified custom preferences, and guard display controls and shutdown.
Add executable sanitizer regressions for routing, retries, selection, storage faults, UI lifecycle and GPS. Both Companion builds and the shared T-Deck regression pass; no physical Cardputer testing performed.
Integrate mjgodat's keyboard/display Companion, USB Companion, Repeater and
Room Server support for Cardputer-Adv with Cap LoRa-1262.
Fix UI retry dispatch and ACK ownership, packet/storage bounds, numeric
input validation, sparse channel selection, optional-display shutdown,
keyboard layout limits, reserved GPIOs and Windows cross-drive includes.
Retain all 350 contacts and queue capacity using the existing contact cache;
account for the custom UI's runtime allocations in the RAM admission gate.
Carry the MultiMote and DejaVu notices with firmware packages and add CI
coverage for all four board roles plus the shared T-Deck Companion.
Validation: all four Cardputer roles and the T-Deck BLE Companion build;
Cardputer sanitizer, UI, layout, ownership, licensing and storage tests;
65 RAM-policy tests and 14 contact-cache tests. PlatformIO ran serially.

New variant variants/m5stack_cardputer_adv for the Cardputer-Adv
(ESP32-S3, 8 MB) with the Cap LoRa-1262 (SX1262 + GNSS):
- Envs: companion_radio_ble, companion_radio_usb, repeater, room_server.
- Board: enables the Cap's antenna path via the PI4IOE5V6408 on the
internal I2C bus (Wire1, G8/G9); Wire stays on the Grove port. LoRa and
microSD share FSPI because the display owns SPI3. TCXO 1.8 V.
- Companion UI adapted from MultiMote/meshcore-cardputer-adv (MIT,
LICENSE.MultiMote), running on the standard companion so the USB
terminal CLI stays available. Contacts/identity stay in internal
SPIFFS; the microSD card is optional (chat history, keyboard layouts).
- Sticky Shift, one-shot Fn with Fn+letter shortcuts, top button (G0)
sends a flood advert, brightness control.
- Text size setting (Normal/Large/Extra large) with DejaVu Sans fonts
generated by tools/gen_vlw_font.py; layouts derive from the font size.
- Power save maps to the companion's powersaving pref; the UI vetoes
light sleep while the screen is on. Low-battery power-off at 3.4 V.
- win_long_cmdline.py: Windows-only -iprefix include shortening so the
ESP32 compile command stays under the 32,767-character limit.
Shared companion changes are guarded by CARDPUTER_ADV_UI: main.cpp
selects CardputerDataStore/CardputerUITask/CardputerMesh, and MyMesh.h
maps the_mesh to the subclass like the PSRAM storage path does.
Tested on hardware (910.525 MHz mesh): radio RX/TX, USB CLI, BLE, UI.

Use compact scalar crypto, reviewed GNSS version parsing and shared CLI reply copies for RAK3401/RAK4631 repeaters. Preserve keys, protocols, commands and configured capacities.
Both Reduced images save 11,580 bytes. SWD measurements on the RAK3401 found scalar-only signing still near 50.9 ms and key exchange near 38 ms. Keep compact field arithmetic off: its extra 4.3 KiB saving adds about a quarter second and delays radio servicing.
Validate Full and Reduced production OTA packages on both boards, focused crypto/GPS/CLI tests, and linked ARM crypto outputs. Include the RAM benchmark harness and scoped results. No live RF packet-loss qualification is claimed.
Declare fixture feature boundaries and SDK mocks explicitly, retain USB recovery ownership checks, and recognize the unified V4 display and read-only diagnostics in contract tests.
Omit unbound forwarding-region callbacks only for exclusive Companion source roles. Reuse the compact neighbor sorter in repeaters for every RPC order and the CLI list, removing duplicate sort implementations while preserving storage and size gates.
Cache each validated OTA descriptor field once and size manifest reassembly to the admitted wire format. Compile reviewed read-only VL53L0X tuning data in flash through a private dependency copy, retaining the original implementation for unknown revisions.
Place 32 existing retained frames in RTC FAST without changing the 224 normal or 128 active-OTA queue capacities. Keep the default backing layout unchanged for other boards and cover ownership, wraparound and OTA transfers.
