Defines an experimental benchmark for evaluating how well our coverage metric predicts evaluation effectiveness through mutation testing.

The concise root README describes the project, its work-in-progress status, and the expectation that case examples will grow, change, or be dropped as we build in plain sight. Prep is external to this repository; runs consume prepared case examples, fixed subset manifests, and a YAML benchmark definition.

The stage descriptions focus on four executable stages: run mutants × eval tasks, compute mutant scores, compute coverage, and correlate the score pairs. The first execution script will be a basic local Harbor loop; NeMo Helix support is planned afterward. The architecture and both SVG figures explain the inputs, component boundaries, shared results directory, and statistical comparison.

This is the documentation-only base of the stack. Implementation PRs #94 → #105 → #106 → #95 → #96 → #97 → #99 inherit the overview and design unchanged. Their detailed CLI guide lives separately in docs/tools.md.

Validation: the five files in this PR are Markdown/SVG only. Local links and anchors, Markdown fences, headers, SVG XML, and whitespace checks pass; the updated figure was rendered and visually inspected. Restacking preserves all source and test files byte-for-byte. No live evaluations or model calls were made.
