- README: add Room Server to "Device Roles" + a build command in "Building"
- ARCHITECTURE.md: role list two -> four (add Room Server + the
previously-undocumented Observer)
- Repeater_CLI_commands.md: note the room server shares this CLI
- boards/example_board/README.md: add the room_server.conf build snippet
Production (LOG=n, ASSERT=n, RTT=n, reboot-on-fatal) is now the prj.conf
default; debug.conf is the opt-in bundle. Removed prod.conf and the
logging.conf auto-include; relocated RTT/ASSERT out of the always-on
platform confs so they no longer override the prod defaults.
Add CONFIG_ZEPHCORE_COMPANION_USB so the USB CDC companion transport
compiles independently of logging (default-y on USB-capable companions,
opt-in on ESP32-S3 via esp32s3_usb.conf). Gate all USB sites behind one
ZEPHCORE_USB_STACK macro.
Rework BLE/USB interface arbitration to first-come-first-served: neither
transport evicts a live session. Make active_iface mutation thread-safe
(mutex + atomic claim) across the BLE callback thread and USB workqueue.
Share the ESP32-S3 USB OTG / console DTS via common dtsi includes; enable
uart0 (GPIO43/44) on station_g2 and xiao so the console reroute works.
getEstAirtimeFor() set LDRO from `sf >= 11`, correct only at BW125. Now
matches the driver's should_enable_ldro() (t_sym > 16.38 ms) so the
estimate's DE tracks hardware DE on every SF/BW. Also drop dead
calcRxDelay() + unused MAX_RX_DELAY_MILLIS.
- src/Mesh.cpp Reverted #ifdef ZEPHCORE_COMPANION block → back to vanilla self_id.copyHashTo
- helpers/ContactInfo.h Removed OUT_PATH_SENT
- helpers/ui-joystick/joystick_defs.h Added OUT_PATH_SENT here (with comment clarifying it's UI-only)
- helpers/ui-joystick/joystick_ui_task.h Removed dead _next_batt_refresh field
- helpers/ui-joystick/joystick_ui_task.cpp Removed _next_batt_refresh(0) from ctor init list
- helpers/ui-joystick/joystick_screens.h MsgEntry::origin[80]→[32]; MAX_UNREAD_MSGS 32→16
- Kconfig DOOM help text now lists both UI activation paths
- ARCHITECTURE.md Same correction in §8.5
- flood retransmit jitter now capped at min(2000ms, 6·airtime) instead of
fixed 2000ms — spreads tighter at SF7, unchanged at SF8
- reactive per-dupe backoff cap now min(2000ms, 12·airtime), keeps
semantic of "push past ~12 relay slots"
- contention ring 16 → 24 for 50-neighbor hilltops
- companions passively track heard floods (warms EMA without forwarding)
and spread their own TX by up to min(1000ms, 3·airtime), hopefully
fixing repeaters missing companion's first transmission
config cleanup:
- move BLE TX buffer bumps (ACL_TX=12 etc.) from zephcore_common.conf to
esp32_common.conf — the Espressif blob needs them, nRF doesn't, and
the bumps were overflowing nRF52840 RAM
- remove CONFIG_ZEPHCORE_MAX_CONTACTS=510 overrides from 5 nRF52840
companion boards; Kconfig default of 350 fits with comfortable margin
(wio prod: 91% → 79% RAM)
- RegionMap::findMatch(): fix 1-byte stack overflow in tmp[] with bounded memcpy
- Packet::readFrom(): add bounds checks before reading transport codes
- Mesh::sendFlood(): release packet on TRACE type and invalid hash_size early returns
- CompanionMesh: add cleanupSignState() called from BLE disconnect to free sign buffer
- ZephyrCompanionUSB: add 2s timeout for partial V3 frames to prevent parser stall
- ui_mesh_actions: replace volatile bool with Zephyr atomic_t for cross-thread state
- CommonCLI: wrap ~40 fs_read() calls in prefs_read() helper with truncation warning
