# Step 0: build-test-harness
|
|
|
|
## Sprint Contract
|
|
|
|
### Objective
|
|
Establish the C++ project skeleton, build system, test framework, and validation script integration required before solver code begins.
|
|
|
|
### Required Reading
|
|
- /AGENTS.md
|
|
- /PROGRESS.md
|
|
- /PLAN.md
|
|
- /docs/README.md
|
|
- /docs/HARNESS_ENGINEERING.md
|
|
- /docs/PRD.md
|
|
- /docs/ARCHITECTURE.md
|
|
- /docs/ADR.md
|
|
- /docs/VERIFICATION_PLAN.md
|
|
|
|
### Scope
|
|
- Choose the Phase 1 build/test path. CMake is recommended unless project constraints require another choice.
|
|
- Add a minimal C++17 project skeleton with one smoke-test target.
|
|
- Wire `scripts/validate_workspace.py` to run real configured checks.
|
|
- Document the build-system decision in ADR if it changes or becomes explicit.
|
|
|
|
### Allowed Files
|
|
- `CMakeLists.txt` or the selected build-system files
|
|
- `src/**`
|
|
- `include/**`
|
|
- `tests/**`
|
|
- `scripts/validate_workspace.py`
|
|
- `README.md`
|
|
- `docs/ADR.md`
|
|
- `PLAN.md`
|
|
- `PROGRESS.md`
|
|
- `phases/1-linear-static-mitc4/index.json`
|
|
|
|
### Explicit Non-Goals
|
|
- Do not implement solver, parser, MITC4, results, or reference-comparison behavior.
|
|
- Do not introduce MKL, TBB, or HDF5 APIs into solver core during this setup step.
|
|
- Do not mark readiness blockers R-004 through R-011 as solved unless this step actually resolves them.
|
|
|
|
### Tests To Write First
|
|
- A minimal C++ smoke test that fails before the test harness is connected and passes after the harness is wired.
|
|
- A validation-script test or self-check proving `python scripts/validate_workspace.py` reports the configured build/test command status.
|
|
|
|
### Reference Artifacts
|
|
- None. This step does not use `references/*.inp` or `references/*_displacements.csv`.
|
|
|
|
### Acceptance Commands
|
|
```bash
|
|
python scripts/validate_workspace.py
|
|
```
|
|
|
|
### Evaluator Checklist
|
|
- The project builds with C++17 or newer.
|
|
- The chosen test framework runs through the validation script.
|
|
- `scripts/validate_workspace.py` no longer reports that no checks are configured.
|
|
- The build-system decision is documented if new or changed.
|
|
- No solver behavior was implemented.
|
|
|
|
### Handoff Requirements
|
|
- Update `PROGRESS.md` with changed files, validation output, and any build-system caveats.
|
|
- Update `PLAN.md` only for changed future work or resolved blockers.
|
|
- Update the matching phase index entry: use `completed` with a one-line `summary`, or `blocked` with `blocked_reason`, or `error` with `error_message`.
|
|
|
|
## Verification
|
|
1. Run the acceptance command.
|
|
2. Confirm the smoke test is executed by the validation script.
|
|
3. Inspect the diff for accidental solver behavior or dependency leakage.
|
|
|
|
## Do Not
|
|
- Do not expand Phase 1 scope to make a build demo more impressive.
|
|
- Do not commit generated build artifacts.
