Measured against a real Montreal database: most messages arrive twice,
through the two repeaters a companion hears, on paths that share their
start and split near the end, with 3-byte hashes. The demo did five or
six short copies through five neighbours.
Our node now hears only two new rooftop repeaters, Villeray and
Rosemont (the terrain hides the big ones), companions lose 7 dB at street
level, and each sender has its own hash width (mostly 3 bytes). Now 91%
of messages arrive twice and 83% of paths use 3-byte hashes. Noor moves
to Côte-des-Neiges to stay in reach, and the traces leave through
Villeray or Rosemont.
The capture finds the Message paths message by its text (a key press
can be lost while the transcript draws) and selects the second path,
since the first is often a straight line.

scripts/screenshots.py runs MeshTerm --demo in the emulator's session,
with no window, and types its way to the main menu, the chat on Public,
the paths of a message, and the map. It saves each screen for the
terminal (80x24, drawn in Cascadia Mono with its own box, braille, and
Powerline shapes), the Cardputer Zero, and the PicoCalc (the emulator's
own raster, at 3x), into docs/screenshots/<set>/.
Two runs give the same pixels: the clock is pinned to 11:42 on Thursday
15 October 2026 in Montréal (time-machine and TZ), and the demo device
plays no background traffic during a capture (PLAY_BACKGROUND). Gabriel
in Beloeil joins the demo, so the message shown in Message paths
arrives on five paths through Mont-St-Hilaire, and the map opens at z10.
Pillow, fontTools, and time-machine join the dev extras.
