The spam filter keeps recent message text and sender keys for its
repeat checks, and panic clear left them in memory. Reset the shared
filter as part of the panic wipe.
Add a broadcast_spam Mesh Lab scenario so messaging validation covers
both admitted and filtered public messages: B must show two
near-copies from A, hide the third, and still show A's next ordinary
message. It runs phone-to-phone and phone-to-watch.
Receivers hard-cap reassembly at MAX_FRAGMENTS_PER_ID (256), but the
generic send path fragmented packets with no caller cap (0xFFFF), so
broadcast file transfers above ~120 KB were fully transmitted yet
undeliverable. FragmentingPacketSender now caps fragmentation at
MAX_FRAGMENTS_PER_ID and reports failure via a new
TransferProgressEvent.failed flag, which surfaces as
DeliveryStatus.Failed in the UI and as a file_send error in the debug
test hook instead of an indefinite wait.
Adds FragmentingPacketSenderTest and a file_oversize mesh-lab scenario
asserting sender-side rejection.
Debug-only broadcast receiver (app/src/debug) exposes mesh operations over
ADB: scan, connect, Noise handshake, DMs, broadcast, announce, file
send/receive with SHA-256 verification, BLE toggle, state dumps, and raw
packet injection. tools/release_gate/mesh_lab.py orchestrates scenarios
(dm, broadcast, file, file_private, raw) on two live devices and emits
evidence JSON.
