The contact page's route graph fanned every path as a free lane from the two
endpoints and averaged shared relays together, so a well-connected node drew as
an acute tangle of near-overlapping lines. Worse, the same physical node could
appear twice: a 1-byte trace hop (27) standing beside its own wide contact id
(27d4396a2967) whenever the short hash was too ambiguous to widen — YUL-Poly
drew YUL-UpperSalaberry as two separate markers.
Redraw the route graph as a layered left-to-right graph (pathgraph.py):
* longest-path ranks put every node in the column of its hop distance, so each
edge steps strictly forward and a relay shared by several routes is drawn once;
* an edge that skips a column routes through invisible waypoints, bending around
the nodes between its ends instead of slicing through them;
* nodes are ordered to cut crossings (barycentre sweeps) then spread down the
full height with their ys pulled toward their neighbours' (PAVA packing), which
straightens each route into a lane and opens the branch angles up;
* first-appearance ordering keeps the layout identical on every repaint.
Kill the double-drawn node at two levels. build_topology now coalesces an
under-specified id into the one longer node it can only be (27 -> 27d4396a2967),
folding their links — fixing the atlas and the scenario ranker too, not just this
graph — while leaving a genuinely ambiguous stub (c5 -> two nodes) alone. The
widget then closes the same gap locally across its own layers, catching a hash
that is ambiguous against the whole contact list but unmistakable among these
paths (be -> be1d1c1dbc4b).
On the node detail page specifically: name every node, not just the two ends
(a relay reads by its contact name, unknown ones keep the honest hash byte), and
draw the target with its own map glyph (repeater, room, sensor) to match the
header. us stays on the left, the target on the right.

The fan-lane route graph clipped every label to a fixed 12-cell budget, so
node names past twelve characters ellipsized even with room to spare. Cap the
label at the physical canvas width instead: a name is kept whole unless it is
wider than the whole canvas (nowhere for the cells to go), and the placement
pass — which already slides an endpoint's label inward or drops a crowded
relay's — decides where it lands. Message-paths endpoints now read in full.

Both trace tools now feed the boards: on a successful trace the session
derives the walk's spec, route, and stats from the reply and offers it to
every discipline, and a walk that sets a record surfaces a ★ note under the
run's aggregates (the walk still records nothing extra — it's the same one
trace per transmission). Scoring is defensive: a hiccup never breaks a
trace.
Trace path can open armed on a given spec, so the trophy case's Trace this
path reopens a record's exact route ready to walk again. The shared route
graph is unchanged; its docstring just drops the pathfinder example.

The Message paths dialog's braille route graph becomes ui/pathgraph.py —
layered paths with per-layer colour and draw priority, caller-supplied
glyph/label callbacks — so the Pathfinder can draw best-ever/session/attempt
routes through the same widget. Endpoint labels lose their beside-the-marker
restriction: they place above/below like relay labels (with an edge-clamped
anchor so a name at the canvas margin still lands), falling back beside only
as a last resort.
