+# CodegenRefCheck
+
+The rest of chaste_codegen's test suite checks generated model code textually
+against the frozen reference files under `chaste_codegen/data/tests/chaste_reference_models/`.
+When a sympy/Python version renders a model differently, a version-suffixed variant file
+(e.g. `--sympy_1_14.cpp`) is added alongside the default file, on the assumption that the new
+rendering is mathematically equivalent to before. This needs to be verified numerically.
+
+This suite compiles every reference model variant as a real Chaste `heart`
+class, simulates it, and numerically compares the result to the corresponding
+baseline model (a **fixed snapshot**) which is a stable basis to compare against.
+A fixed snapshot is used as the baseline so that it does not silently drift when
+new commits are merged in. If the baseline ever needs to be shifted forward,
+`freeze_baseline.py --force` can be used to make a new snapshot into `baseline/`.
+
+This is a quick numerical check that supplements the `TestCodegenLong` Chaste
+tests that perform more rigorous end-to-end testing.
+
+## Building and running the tests
+`CodegenRefCheck` is a small Chaste user project. It contains `TestRefCheckCompareAll.hpp`
+which reads the manifest the harness generator creates on the fly (`test/RefCheckManifest.hpp`)
+and numerically diffs each variant's `.dat` against its baseline via Chaste's existing
+`CompareCellModelResults` helper (`heart/src/fortests/RunAndCheckIonicModels.hpp`).
+
+`generate_refcheck_harness.py` is the test harness generator. For every
+(scheme, model, variant) tuple, it creates **one standalone Chaste project** in
+`<CHASTE_SOURCE_DIR>/projects/RefCheck_<scheme>_<model>_<variant>/`
+(`variant` is `Baseline`, `Default`, `Sympy111`, `Python311`, etc.), each holding
+one variant consisting of a generated `src/<header>.hpp/.cpp` pair and a
+generated CxxTest runner that constructs a cell, runs it, and writes a `.dat` file.
+Every tuple gets its *own* project to avoid name collisions. If you want to inspect
+what was generated, review the resulting content under `<CHASTE_SOURCE_DIR>/projects/RefCheck_*`.
+Check `<CHASTE_SOURCE_DIR>/projects/CodegenRefCheck/generated_manifest.md` for
+what was generated or skipped.
+
+To build and run this suite, checkout Chaste, point `CHASTE_SOURCE_DIR` at it,
+build the `heart` module, and run `run_all.sh` to regenerate → configure → build → test,
+end to end.
+
+```sh
+CHASTE_SOURCE_DIR=/path/to/Chaste ./run_all.sh
+```
+
+`TestRefCheckCompareAll`'s output prints one PASS/FAIL/NO-BASELINE/ERROR
+line per (scheme, model, variant) tuple plus a totals line. ERROR means a `.dat`
+file was missing (e.g. a CVODE-only model on a build without `CHASTE_CVODE`,
+or a reference `.cpp` failed to compile) rather than a genuine numerical mismatch.

+newer master - never as a side effect of the normal generate-and-test loop.

+sibling variant files (a legacy `.cpp_python36` rendering, or a `--sympy_X_Y`/`--python_X_Y`

+"""Creates a Chaste numerical cross-check harness from the reference model
+corpus in this repository.
+
+This generates one standalone Chaste project under
+<CHASTE_SOURCE_DIR>/projects/RefCheck_<scheme>_<model>_<variant>/
+for every "case" (scheme, model) found in the reference model corpus, and for
+every "variant" rendering of it (e.g. sympy_X_Y variants), plus one more per
+case for that model's rendering in the frozen baseline/ snapshot - the fixed
+basis every other variant is compared against.
+Each project contains:
+  - the reference .hpp/.cpp for that one case variant (scheme, model, variant).
+  - one CxxTest runner that constructs the generated cell, runs it, and writes a
+  .dat file into a shared case (scheme, model) output folder.
+
+Each case variant (scheme, model, variant) gets its own project rather than
+grouping several into one shared library to sidestep name collisions during
+linking. For example, some scheme pairs (e.g. Cvode vs. Cvode_with_jacobian)
+reuse the same class name for the same model. Also, every dynamically-loadable
+model defines an identical global `MakeCardiacCell` factory function regardless
+of which scheme/model it is.
+
+The central CodegenRefCheck/ project has no generated cell code of its own. It
+numerically diffs every variant's .dat output against its model's baseline via
+Chaste's existing CompareCellModelResults helper.
+
+See run_all.sh for the full generate -> configure -> build -> test sequence, or
+README.md for the manual steps.

+
+    Deriving the stem from the .cpp's own filename instead would be simpler, but doesn't work:

+    - Variant .cpp files have no paired .hpp at all. A `<model>--sympy_1_14.cpp` shares the

+    - The stem is a compile-time contract, not just a lookup key. write_tuple_project() copies
+      the pair into the project as `<stem>.hpp`/`<stem>.cpp`, so the header must land under the
+      name the .cpp asks for or the project won't build.
+    - A few .cpp files name a header that does not exist under that name anywhere, e.g.
