Module analysis 

Coverage attribution: combine a head per-line report with a DiffModel (and optionally a baseline report) into the metrics a reviewer wants.

• Patch coverage — of the lines this diff added, how many are covered. Needs only the head report + diff; immune to line-shift because added lines exist only in head.
• Uncovered new lines — the explicit file:line list of added lines that are not covered (the actionable output).
• Project delta — per-file and total before/after coverage (baseline).
• Indirect changes — lines whose coverage flipped without their content changing, found by aligning base↔head through the diff (baseline).

PatchCoverage

Covered / uncovered tally over a set of lines.

Enums

DiffScope

Which files the project-delta and indirect-change sections report on.

Functions
