A walk is any trace — it starts and ends at our node (a Trace path route
directly, a Trace target boomerang just the same) — so every walk home can
be measured and scored. services/records.py owns that scoring: measure a
walk once (distance, reach, node counts, weakest link, enclosed area) and
offer it to every one of six disciplines it places in — Longest distance,
Farthest node, Most nodes, No revisits, Weakest link, Biggest loop.
walk_from_trace turns a reply into its re-walkable spec, canonical route,
and stats in one call.
Records persist per (category, hash width) in the discovered_paths table
(schema v11) — the 64-byte path field makes each width its own game — kept
top-5 with spec-dedupe and worst-first pruning, stamped with the app
version. Disciplines carry plain descriptive names; their ids stay stable
database keys so stored records survive the naming.
