CYCLE 3 Data Preparation Report v0.1

Date: 2026-04-19Status: Completed

Objective

Convert Cycle 3 raw datasets into unified operational tables:- D02.csv (180 samples),- A01.csv (320 samples),- D03.csv (260 samples).

Raw inputs used

• datasets/cycle3_raw/D02/ca-GrQc.txt.gz- datasets/cycle3_raw/D02/email-Eu-core.txt.gz- datasets/cycle3_raw/A01/STS-B.zip- datasets/cycle3_raw/D03/UD_English-EWT-r2.17.tar.gz

Pipelines

• Script: datasets/cycle3_work/build_cycle3_inputs.py- Output directory: datasets/cycle3_inputs/- Generated outputs:- D02.csv- A01.csv- D03.csv- metadata.json- run_summary.json

Final tallies

• D02: 180 lines- A01: 320 lines- D03: 260 lines

Methodological note

For D02 a deterministic Phi proxy (density/context) useful for the phase was appliedoperational validation of the cycle; it does not yet constitute the final test for validated status.
