Aisle Path Trace: Ordered Zone Sequences Through Corridors
Lists the zones somebody walked through, in order, with no camera and no name attached.
Contested Space · Contested capability
Latent emits a reading. It does not switch cameras, unlock cages, cut power or open a ticket. Your VMS, PoE switch or access controller does that, on your side of the boundary. A Latent blueprint contains no executable code, no remote URLs and no device secrets — by schema, not by policy.
No face, no plate, no MAC, no device identity, no payload. A movement signature is a shape moving through a room, not a person. Nothing stored here resolves to an individual.
Two people moving together read as one disturbance. Tailgating is precisely the case this cannot separate on its own. CRAC airflow, fan walls and tape robots produce night-shift ghosts until the baseline learns them.
Across Camera Shield Jam the mesh and the wake never fires. Two people moving together read as one disturbance. Re-rack a row and the fade map is wrong until you recalibrate.
Each node mints its own key over USB, in your hand. Physical possession is the root authority: a device that cannot prove physical presence is refused enrollment outright. A cloud pairing PIN is a weaker ownership claim and is never treated as liveness.
Every reading is attributable to a device id, profile id, hardware id and firmware version recorded at install and verified by mutual HMAC-SHA256 proof over an LFW1 nonce exchange. A node whose proof did not verify is marked untrusted, not merely offline.
Completing an installation is a high-risk action. It requires your explicit browser approval, an approval snapshot that still matches, an idempotency key, and heartbeats less than three minutes old. There is no silent commissioning.
How enrollment worksProperties you can map to your own controls
These are properties, not certifications. Latent does not assert compliance with any framework on your behalf.
Mapped to a shared offline runtime family and usable with a recording or compatible ESP32 CSI stream.
Published physics or adjacent results support the hypothesis; capability-specific product and site validation are still required.
Time-in-zone estimate from calibrated presence transitions.
No compatible ESP32 stream is connected. Use the bundled Camera Shield recording; it demonstrates the shared Zone dwell runtime, not independent proof of this capability.
Intended capability
This describes the intended outcome. Readiness is shared-family mapped, evidence is class B, and a catalog mapping or recording is not proof of this outcome at a real site.
Solution blueprint
This exact kit is one of 191 first-class designs. It includes geometry, objects, nodes, wording, scenarios, installation, limitations, and catalog-bound readiness.
No rendered revision is available yet.
Bundled recording
This is one recorded vertical scenario. It is not separate validation of every capability in the catalog.
A moving human body is a large, water-rich scatterer that perturbs every link whose Fresnel volume it crosses, and it crosses them in the order it walks. At ~6.6 Hz ambient sampling a 1.5 m/s walker advances about 23 cm per sample — ample for ordering zone entries and exits, nowhere near enough for continuous coordinates. Metal-rich aisles amplify disturbance sensitivity while smearing exact position, which is precisely why the output is a sequence and not a track.
Per-link Doppler band energy + amplitude variance -> per-zone rolling baseline with a mechanical-rhythm term (CRAC and fan-wall periodicity subtracted) -> zone dwell segmentation with entry/exit hysteresis -> compartment Kalman across adjacent zones (people cannot teleport) -> ordered zone sequence with per-zone dwell durations.
This is a capability design path. Components may be shared with other catalog entries; it is not presented as a unique algorithm.
Own-hardware: 10 nodes across two corridors and three aisles, 300 scripted single-person walks on six routes versus a two-person condition, report zone-sequence edit distance against floor-marker ground truth and the merge rate for two people in adjacent zones; then 14 nights of unoccupied baseline with mechanical plant cycling, to count ghost sequences before and after rhythm subtraction. WiMANS and OPERAnet for multi-subject separability priors.
'Aisle Trace' — a lens-free movement record for halls where cameras are banned or blind, sold to the physical-security chief as an ordered list of zones and dwell times, never as a floor-plan track and never as an identity.
A quiet reading is not an all-clear. If nodes are stale, degraded or jammed, this runtime says so explicitly. It never infers safety from missing data.
