Evidence-ready calibration intelligence

Every drift detection, technician dispatch, and post-calibration validation step is exportable as a signed bundle — mapped to ISO-oriented audit language for insurers, OEM programs, and fleet safety boards.

Detect

Residual events

Mahalanobis scores, changepoint flags, and tier routing (NOMINAL → CRITICAL) with VIN-scoped timelines.

Act

Guided intervention

Repair network workflows gated on pass/fail validation — not subjective sign-off alone.

Prove

Signed exports

Chain-of-custody payloads via /v1/evidence/bundle and SDK helpers.

POST /v1/evidence/bundle
{
  "vin": "EVB-20260603-B7F2",
  "drift_event_id": "evt_8f2a",
  "include_validation": true
}

Pilot-ready audit trail

Bundle generation ties telemetry ingest, scoring responses, and closure metadata — designed for shadow-mode pilots before any in-vehicle actuation.

Evidence field glossary

Signed exports from GET /v1/evidence/bundle/{event_id} use format version 2.1. Fields below map to insurer and OEM audit reviews in shadow-mode pilots.

Field	Type	Description
`event_id`	string	Unique evidence bundle identifier (e.g. EVB-20260603-B7F2)
`vehicle_id`	string	Fleet VIN or operator vehicle key at detection time
`timestamp`	ISO-8601	Detection wall-clock when tier was classified
`format_version`	string	Bundle schema version — currently 2.1
`tier`	enum	NOMINAL, CAUTION, or CRITICAL at export
`measurements`	object	camera_drift_deg, radar_drift_mm, lidar_drift_mm, mahal_distance, health_score
`chain_of_custody`	array	Ordered steps: TELEMETRY_RECEIVED → TIER_CLASSIFIED → EVIDENCE_SIGNED
`iso_standards`	array	Referenced frameworks (ISO 26262, ISO 21448, FMVSS 127)
`signature`	string	HMAC-SHA256 digest over canonical bundle JSON
`before_state` / `after_state`	object	Tier and drift delta before/after the triggering event
`validation_result`	object	Post-repair pass/fail, workflow type, operator notes
