Reporting & Analytics is a data-processing and export module developed as part of ETS2 EU Digital Tachograph. It transforms canonical driver history into readable summaries, completeness evidence, violations, compensation information, and human- or machine-readable outputs.

An early minute-by-minute PDF exceeded 40 pages for one game day. I separated stored truth from presentation: precise activity remains available for rules and diagnostic CSV, while the report layer collapses adjacent records into blocks and inserts unresolved gaps into the timeline. The PDF stays compact without discarding source detail.

Completeness is explicit: the model exposes activity and gap minutes, coverage, range length, balance, pending rest allocation, and evidence status. Queries use the same canonical branch as the rule engine, so abandoned rollback data does not return. Outputs include localized PDF, raw activity CSV, compensation CSV, VTC JSON, and a SHA-256-protected session envelope. The module demonstrates temporal aggregation, range projection, data-quality modelling, format-specific serialization, localization, and automated verification.
