- BaseChatMesh/ContactInfo/ChannelDetails restored to upstream text, ZephCore
changes fenced; added to the Shared-file list
- upstream names: handleCmdFrame, writeOKFrame/writeErrFrame,
addToOfflineQueue, queueMessage; dead dequeue removed
- handleCmdFrame split into handleCmd<Name>() in upstream order;
CMD_SEND_PATH_DISCOVERY -> _REQ
- CompanionMesh::handleCommand as the single CLI entry point; over-the-air
TXT_TYPE_CLI_COMMAND from flag-0x10 contacts (upstream command set only)
- V-contact moved to app/VContact.cpp, protocol constants to
app/CompanionProtocol.h; comment diet (image-identical)
- Mesh, Dispatcher, Packet, packet pool and the core headers rebuilt from
Arduino MeshCore's text; ZephCore changes re-applied, each fenced
`// ZEPHCORE:` (diff vs upstream: 4540 -> 1147 lines)
- upstream header layout; MainBoard gains handleCommand/loop and the other
upstream members; RNG::nextInt back in Utils.cpp
- packet logging moved to the roles' log hooks (helpers/PacketLog.h)
- zero-hop direct ACKs deduplicated and length-checked as upstream
- RadioIncludes.h -> src/, LoRaConfig.h -> helpers/
- .editorconfig: shared files keep upstream formatting
Verified: 10 role builds, per-function disassembly review, bench DM/ACK
regression (T1000-E, Wio L1, XIAO S3 on 1.17.4) incl. via live repeater.
Swap the vendored orlp/ed25519 (frozen ~2017 ref10) for Monocypher
4.0.2, an actively maintained, audited, single-file implementation.
The persisted private key keeps its 64-byte expanded layout
(clamped SHA-512(seed) scalar a || nonce prefix), so identities
written by older firmware load, sign, verify and key-exchange
unchanged -- no re-key, no storage migration, full wire
compatibility with the existing mesh and Arduino MeshCore.
Because the stored key carries no seed for Monocypher's high-level
EdDSA API, Identity drives signing from the low-level primitives
(crypto_sha512 + crypto_eddsa_reduce/scalarbase/mul_add); verify
uses crypto_ed25519_check and ECDH uses crypto_eddsa_to_x25519 +
crypto_x25519. Nonce material is now wiped after signing.
Validated byte-for-byte against the previous orlp output via a
known-answer harness (keygen, sign-from-expanded-key, verify
accept/reject, X25519-over-Ed25519 shared secret) before the swap.
Frees ~42 KB of flash: orlp linked ~55 KB (dominated by its ~30 KB
ref10 precomputed tables); the Monocypher Ed25519/X25519/SHA-512
paths link ~14 KB, with --gc-sections dropping all unused algos.
wio_tracker_l1 pristine build: FLASH 54.14%, links clean.

- track real RTC sync source on the joystick Time screen
- gate joystick-only UI helpers behind stub headers so non-joystick builds skip the extra code without #ifdef at every call site.
The phone app interprets path_len with an unconditional `& 63`, so
the OUT_PATH_SENT (0xFE) sentinel we were writing into the
offline-queue frame became "62 hops" + 4 bogus path bytes in the
app's UI. There are 0 LoRa hops between the sender (us) and the
phone viewing the message — path_len = 0 is both correct and
renders cleanly as "direct / 0 hops". The "(>>✓) " / "(>>✗) " body
prefix still distinguishes wio-originated messages from incoming.
OUT_PATH_SENT remains the marker for the joystick UI's own local
entries (UnreadScreen, _ch_previews) — formatHopCount handles it
explicitly so it's safe there.
