+
+## Task
+Create controlled sample smoke conversion tests for the MVP corpus.
+
+The tests should exercise the end-to-end pipeline on a small selected subset or page range first, then document which full documents are suitable for manual or slower regression runs.
+
+## Sprint Contract
+- Done means: at least one text-layer sample and one mixed/scanned-risk sample can be converted in a controlled test path.
+- Hard thresholds: tests have runtime bounds; sample selection comes from `samples/metadata.json`; generated output is checked with quality gates.
+- Files owned: `tests/`, sample metadata updates if needed, `PROGRESS.md`, `phases/7-mvp-quality-hardening/index.json`.
+- Dependencies: CLI/runtime and renderer phases complete.
+
+## Acceptance Criteria
+```powershell
+python scripts\validate_workspace.py
+.\venv\python.exe -m pytest tests
+```
+
+## Verification
+1. Run the acceptance commands.
+2. Record sample coverage and any skipped slow tests in `PROGRESS.md`.
+3. Update this phase index.
+
+## Do Not
+- Do not make every validation run process all long PDFs if runtime becomes impractical.
+- Do not commit generated `output/` bundles.
+- Do not weaken quality gates to pass broken output.
