A channel message of our node that mentions Dave gets his answer a few seconds later, and the answer mentions our node. The answers are a table in the demo script. Our node uses three bytes for each hop, as most of the mesh does, so a trace uses two.
The video's tour now selects the two paths of a message in turn, types a question to Dave so that the mention becomes a chip, and shows his answer with our star. The trace shows its new records, and the map zooms from the city to the streets around our node.

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.

The demo's conversations are plain English about ordinary things: the
mesh, the meetup, a bike ride, the weather, a family dinner. The props
are gone: no poutine, smoked meat, or tuque, and Poutine Patrol and
Bixi Bandit are now Steve K. and Nico R. Our node is Alex Base. The
room, the sensors, two channels (#cycling, Family), and the regions
(south-shore, west-island, mtl-west...) have English names.

The virtual clock of the demo script stands for 11:42 on a weekday, not
19:30. Today's lines move into the morning: Mathilde arrives at 10:05,
the smoked meat run for noon is planned at 11:20, and the dinner on
Famille moves to yesterday. A test checks that each line is sent while
its sender is heard on the mesh.

meshterm --demo runs the simulator in a synthetic Montréal mesh: 14
repeaters on the high points (Mont-Royal to Mont-St-Hilaire), rooms,
sensors, and about twenty companions, all invented. A log-distance
link model decides who hears whom, so floods arrive on several real
paths and traces walk real routes.
At each start the demo writes its own directory (<config>/demo) again:
300 days of adverts and a dense week of traffic, bilingual channel,
direct, and room conversations whose packets decrypt, traces with
their trophy-case records, neighbour tables, a joined room, admin
passwords, regions, and Watchtower alerts. Every value comes from a
fixed seed and an age before now, so each run gives the same data.
The device plays the live traffic from the same seeds.
The repository writers that stamp now take an optional time, and
record_observations stores a batch in one commit. The test world of
--mock is unchanged.
