PowerBoost × LightShip · ChatGPT Report · 42-PID Validation Segment

Short Segment Validation Report

Pipeline test for the expanded OBDLink PID set. StartTime = 07/06/2026 11:36:16.7277 AM. This report emphasizes schema coverage, sampling cadence, signal availability, and failure modes before the Saturday trip data arrives.
Executive engineering conclusion

The expanded file is usable for the ChatGPT Report pipeline, with caveats from segment length and flagged channel gaps.

This short segment contains 698 numeric rows across 43 columns. Median sweep interval is 2.0000 s. Distance covered is 12.63 mi, fuel consumed is 0.5985 gal, and ProPower AC export is 0.000 kWh. Treat fuel-economy conclusions as provisional because the segment is short.

Validation Issues

No blocking issue found

The file appears structurally usable for the ChatGPT Report pipeline. Remaining limitations are mostly segment length and missing TrackLogger/wind data.

Interpretation

This validation report confirms whether the input signals exist. A real TurboAssist conclusion requires matched State A/B windows, grade/wind normalization, and LightShip battery energy spent during assist.

Nightly Engineering Decision Record

07 · CARRY-FORWARD

42-PID dry run

The parser can ingest this expanded schema and populate the ChatGPT Report format. The actual trip report should add TrackLogger and HRRR wind merge before interpreting aerodynamic residuals or load-normalized fuel deltas.

Short segment limitation

This file is useful for validating signal coverage and cadence. It is not long enough to support robust mpg, ProPower yield, wind residual, or thermal-enrichment conclusions.

Saturday readiness decision

Use this report as the preflight template. For full legs, attach OBDLink CSV, TrackLogger, wind CSVs/notes, fuel gallons, and LightShip SOC start/end so the report can move from schema validation to engineering evidence.
