Read project-tasks.csv and the notes in this folder. Create output/project-report.xlsx with source rows, formulas and a summary by project, plus output/summary.docx. Compare planned and actual hours only for done tasks; do not turn the missing actual hours for T03 into zero. Keep all eight source tasks. Report the pending item separately and identify source task IDs. Preserve the inputs and write only inside output. Show your checks and any errors. Ask before installing dependencies or using a network service. Do not send or publish anything.
