# Todo 52.10 Benchmark Bundle CLI Contract Plan

**Status:** done

## Goal

Align CLI integration tests and report discovery with the atomic bundle layout introduced by Todo 52.9.

## Observation

The CLI still returns the report paths supplied by `write_benchmark_report()`, but four tests discover reports independently with root-level `*.json`/`*.md` globs or attempt to read every output-directory entry as a file. The new layout intentionally exposes a timestamped bundle symlink containing `report.json` and `report.md`, plus a private backing directory.

## Scope

- Update CLI tests to use the exact `json_report` and `markdown_report` paths printed by the command, or inspect the single published bundle symlink.
- Do not inspect private dot-prefixed bundle backing directories as public reports.
- Preserve assertions for CLI overrides, exit codes, cardinality system errors, report redaction, and matching JSON/Markdown contents.
- Avoid adding compatibility copies at the output root because that would restore the two-path publication race fixed by Todo 52.9.

## Files

- Modify: `tests/test_benchmark_cli.py`

## Verification

- `uv run pytest tests/test_benchmark_cli.py -q`
- `uv run pytest tests/test_benchmark_reporting.py tests/test_benchmark_cli.py -q`
- `uv run pytest`
- `git diff --check`
