S0-AN-01: Findings Normalization & Schema

[ezeanyicollins]

Scope: Normalize static analysis findings (Ruff, Semgrep) into a unified schema.

Tasks:

• Pin Ruff and Semgrep versions.
• Create baseline configs (.ruff.toml, semgrep.yml).
• Export findings as JSON with consistent schema.
• Define schema: schemas/findings.v1.json.
• Normalize output (deduplicate, unify file:line format, add severity labels).

DoD: Running Ruff/Semgrep in CI produces a valid findings.json matching schema.
