Merges in the meshtastic agent's now-finished work alongside this session's
continuation: stock-peer (3ccc) PKI-capability is now stamped through
get_contacts -> refresh_contacts -> MeshPeer.pkc_capable, so a directed DM to/from
a PKC-capable stock Meshtastic peer correctly shows the E2E pill on the Sent row,
not just received messages. Confirmed live: .198 sees "Meshtastic 3ccc" with
pkc_capable=true.
Also fixes two real interop/correctness bugs found while live-testing the
Reticulum <-> Sideband link:
- Receive: the daemon only ever read LXMF's plain-text content, silently
dropping native FIELD_IMAGE/FIELD_FILE_ATTACHMENTS fields — a stock
Sideband/NomadNet photo vanished into a blank-space message. Now decoded
into the same ContentInline typed envelope our own attachments use.
- Send: images to a non-archy (stock) peer now use native LXMF FIELD_IMAGE
instead of our own opaque CBOR wire format, which Sideband can't decode.
- Root cause of a garbled MC-chunk-fragment bug: TypedEnvelope.v/.sig (the
OUTER wrapper every message type uses) serialized raw bytes as a CBOR
array-of-integers instead of a native byte string, bloating every
message on the wire ~2-3.5x — enough to push even a tiny ReadReceipt
over the 140-byte single-frame chunking threshold. Root-caused by
reading ciborium's deserializer source directly (deserialize_bytes only
works within its internal scratch buffer; deserialize_byte_buf streams
unbounded).
Frontend: consolidated the attach/record buttons into a single animated "+"
menu (was overflowing the compose row).
857/857 tests pass. Verified live across all 5 deploy-roster nodes.
