NADIR
Glass QA Evidence at close National network Non-binding LOI

Safelite AutoGlass · Post-repair ADAS intelligence

Signed calibration evidence at every windshield close.

After windshield R&R, forward-camera pitch and yaw drift silently degrades AEB and lane-keep performance. NADIR scores residual risk in shadow, then attaches cryptographically signed evidence bundles to work orders — reducing comebacks and giving fleet partners audit-ready proof.

Glass scenario in Calibration Lab Full brief (MD)

Two-phase pilot

Shadow first, then evidence at repair close.

Phase 1 · Weeks 1–6

Shadow QA

  • Score every ADAS glass job after close — no release process change
  • Compare NADIR tier vs QA checklist and 30-day comebacks
  • Weekly location heatmap + sample evidence bundles
  • Technician training with Calibration Lab glass scenario

Phase 2 · Weeks 7–12

Evidence at close

  • Gate: ≥80% technician adoption in Phase 1 locations
  • Signed NADIR export attached to work order before release
  • Target ≥95% evidence completeness on ADAS jobs
  • Fleet customer reporting addendum (optional)

Data requirements

Work-order + post-repair ingest

  • Work order ID, location, ADAS flag, calibration performed
  • Post-close telemetry or scan residual proxy
  • 30-day comeback ticket feed for ground truth
  • Control locations matched by DMA (A/B cohort)
  • POST /v1/telemetry/ingest at close (Phase 2)
  • Full schema in data requirements doc

Set the national standard for post-glass ADAS QA.

We will send the full brief, LOI exhibit A, and a live Calibration Lab walkthrough using the glass misalignment scenario.
