GreenOps & FinOps Calculation Module (v1.0)

1. Objective & Context

This command-line module has been developed for the automated and reproducible calculation of CO2 emissions (GreenOps) and resource costs (FinOps). The tool is built with a strong focus on auditability, traceability and compliance, suitable for high-security and regulated enterprise/government environments.

2. Architecture & Security Principles

To ensure the integrity of the host system, the Immutable Infrastructure principle is used

• Host OS: Fedora Silverblue (Container-first, read-only root).
• Runtime: Insulation via Toolbx containers.
• Dependencies: Strict separation via Python Virtual Environments (venv).
• Validation: 100% Test-Driven Development (TDD) via pytest.

3. Installation & Validation (Audit Trail)

Follow these steps for an isolated execution:

1. Activate the environment: source venv/bin/activate
2. Run the unit tests: pytest test_greenops.py-v

4. Incident Logbook (Post-Mortem)

Incident: TDD-001 (Syntax & Parsing Error in Test Phase) Symptom: Test module could not be initialized (collected 0 items). Root Cause: Manual interaction with a graphical text editor () led to corrupt filenames and unauthorized Bash syntax ( << EOF`) within the Python runtime. Resolution & Prevention: Human interaction minimized. Implementation of direct CLI-based file injection (Infrastructure as Code principles) to prevent future syntax corruption.
