Journeys Remembered As Paths, Not Points.
Archive-native path-shape search research · ZPE-Geo · G1 synthetic pass · real AIS labels blocked
Live experiment. Not a release. Ambition headlined. Claims bounded.
Location data tells you where something was. It often misses what the journey was doing.
ZPE-Geo is testing whether a path can be remembered by its shape: harbor approach, channel transit, stop, turn, drift, return. Those are not just points on a map. They are behavior.
The first surface is synthetic because it can be labelled cleanly. Real AIS labels and stronger baselines still have to decide whether the idea survives outside the lab.

GPS captures where you were. it cannot tell you what the journey looked like.
A route is not its waypoints — it is its arc.
GPS logs, GeoJSON files, parquet tables: a journey today becomes a list of timestamped coordinates. The shape between them — its curve, its arc — is inferred later, or lost.
ZPE-Geo now tests whether packet-derived route features can answer behavior queries after originals are dropped from the search path. Synthetic AIS passes; real labels, H3/geofence retrieval, queryable compression, and qdelta pressure remain the gate.
Every metric stays tied to the archive-native search gate.
Same trajectory bytes,
same query results on fixtures.
The G1 pipeline now locks a query contract, encodes trajectories, drops originals from the search path, and emits route-shape evidence packets. The synthetic AIS suite replays cleanly; real labelled AIS is still the authority blocker.
The deterministic claim is narrow: same declared inputs, same packet artifacts, same synthetic retrieval result. It does not prove commercial archive search, legal custody, or standard compatibility until real labelled AIS and independent replay receipts exist.
Synthetic route labels are not enough. The next gate needs real AIS route-behavior labels, neutral seeds, fair baselines, query-class contracts, and receipts showing the archive can be searched after lossy encoding. No compliance, custody, or standard claim is made here.
EVERY JOURNEY BECOMES a queryable path.
The aim is not a better mapping system. It is the archive beneath one. When a trajectory keeps its shape, a route can be stored compact and retrieved by the path it traces — searched by behavior, not by timestamp. Reaching it depends on real labelled AIS, H3/geofence pressure, queryable-compression pressure, and branch tests from the biocomputation research queue.
