coverage.renderer

Render a CoverageStore to an HTML report directory.

The report layout follows the familiar gcovr information architecture:

  • index.html — project summary (aggregate + per-tier breakdown) and a sortable file table.

  • files/<mangled_path>.html — per-file annotated source with a file summary block, a legend, and a code table that shows per-tier hit counts and branch status alongside the source.

Tier ordering is read from store.tier_order (the precedence order established at load time, first = highest). When the store has no tiers — typically because the run produced no coverage data — the renderer falls back to ("system",) so the templates still have something to iterate. All per-tier columns, percentages, and the winner-take-all row coloring on the annotated source view are driven by that list, so adding a new tier requires no changes here.
