NADIR Apex — Algorithm Tier Deliverable & Pricing

Premium forensic lane

What Apex adds above Meridian

Weighted ensemble across BOCPD, spectral GLR, and HSMM virtual detectors — plus mock CRLB ellipsoids, factor-graph evidence theater, and attribution boost on hard multi-modal scenarios.

3-detector ensemble

Weighted vote fusion

Mahalanobis + spectral GLR + BOCPD + HSMM stubs — median-weighted tier vote on every frame.

Attribution boost

Dominant-modality lock-in

Higher attribution hit rate vs Meridian when ensemble agrees on CRITICAL — insurer dispute ready.

CRLB ellipsoid

Identifiability glyph

Mock Fisher-information ellipse from extrinsic drift — 3D Fleet Twin preview in production Apex.

Evidence theater

Factor graph + bundle

Forensic HTML appendix with chain-of-custody preview and geodesic replay stub.

Ingest payload shape

Same JSON schema across tiers — algorithm depth is selected by org plan and ?tier= routing.

camera_rotation_matrix

9-element row-major rotation vs baseline. Primary signal for extrinsic drift.

radar_range_bias_m

Range systematic error in meters — converted to mm in residual vector.

lidar_registration_error_m

Cross-modal registration residual for fusion disagreement detection.

timestamp_quality

sync_ok and jitter_ms — gates unreliable frames before scoring on Meridian+.

organization_id

Resolved from API key context — strict org isolation on every fleet record.

Terminology

Glossary for buyer conversations

Mahalanobis distance

Multi-sensor drift vector fused into one statistical distance — core signal on every tier.

Extrinsic drift

6-DOF misalignment of camera/radar/lidar relative to vehicle frame.

Shadow mode

Advisory analytics only — no ECU writes or in-loop vehicle control.

Tier gate

NOMINAL / CAUTION / CRITICAL classification from residual thresholds.

Chain of custody

Signed evidence bundle metadata for insurer and auditor review.

Survival curve

Time-to-tier exceedance probabilities (Meridian+).

CRLB ellipsoid

Fisher-information uncertainty glyph for 3D twin (Apex).

Idempotency-Key

POST replay protection — cached response on duplicate ingest.

Org isolation

API key from Org A cannot read Org B fleet records.

Exhibit A

LOI attachment with week-1 pilot metrics JSON.

Extended FAQ

Integration & commercial

How do API keys map to tiers?

Org-level plan sets default algorithm lane. Pass ?tier=apex on scoring routes when permitted by scope.

What telemetry frequency is required?

Daily batch minimum for pilot; hourly or event-driven for production CRITICAL sensitivity.

Can we self-host?

NADIR cloud is default; edge gateway pattern documented in NADIR_SDK/examples/edge_vehicle_gateway/.

What vehicles are supported?

Any ADAS-equipped van, shuttle, or passenger vehicle with camera/radar metadata in telemetry.

How does billing work?

Per-vehicle per month at $8.50 — prorated on tier changes mid-cycle.

Is there a free tier?

Developer sandbox with 12-vehicle sample fleet — $0 for integration testing.

What about Echo archival?

Batch replay add-on — can replay stored telemetry at Meridian or Apex depth.

How do webhooks sign payloads?

HMAC-SHA256 with org webhook secret — verify utils in nadir_sdk.webhooks.

What's in the weekly digest?

Tier counts, CRITICAL queue delta, top drift vectors, Exhibit A summary metrics.

Who owns the data?

Customer telemetry — NADIR processes under DPA; evidence exports are customer-controlled.

FAQ

Apex questions

When does Apex make sense over Meridian?

OEM field programs, insurer evidence requirements, or fleets needing 3D twin + knapsack prioritizer.

Is Apex safety-certified?

No — shadow-mode advisory analytics on every tier. See claim boundary on all pages.

Can we mix Apex on a CRITICAL subset only?

Yes — per-vehicle tier assignment is supported in org billing.
