Bump marimo-precompute pin to >=0.3.6#9
Merged
Conversation
Parallel LAMMPS force evaluations accumulate small floating-point differences (~4e-8) due to summation order in domain decomposition, which exceeds np.allclose default atol of 1e-8.

Not sure this is quite right yet, hold off merging. Will fix it ASAP. |

marimo-precompute 0.3.5 is the first 0.3.x release that actually works
under Pyodide. 0.3.0 through 0.3.4 each shipped with at least one WASM
regression (custom loader format changes, threading.Thread refusals in
both restore_cache and save_cache, missing BLOB_DESERIALIZERS import in
marimo 0.23.1) that slipped through an e2e test which pinned to PyPI
instead of testing the local checkout. 0.3.5 includes a new e2e fixture
that builds from wheel and serves locally, so future breakage is caught
in CI.
No notebook code changes needed — none of the demos pass method=
explicitly, and 0.3.5's default ("lazy_precompute") is picked up
automatically. Also gitignore examples/__marimo__/ (local marimo-edit
session artifacts).

Summary
marimo-precomputePEP 723 pin from>=0.2.3to>=0.3.6in all four demo notebooks.demo1_lj_dimer.wasm.htmletc.).examples/__marimo__/to.gitignore.Why
marimo-precompute0.3.6 is the first 0.3.x release that actually works against the marimo version Pyodide bundles (0.23.1 via conda-forge). The 0.3.x line replaced the old customNumpyJsonLoaderwith a subclass of marimo's new built-inLazyLoader, which took six tries to get right:LazyLoader.restore_cachespawns threads; Pyodide refusesthreading.Thread.start()— override with sequential loaderBLOB_DESERIALIZERSonly exists in marimo 0.23.2+ — replace with inline extension dispatchsave_cacheALSO spawns threads — guard with WASM checkItem.type_hintonly exists in marimo 0.23.2+ — usegetattr(..., None)Upstream now has an e2e parametrised over marimo versions (0.23.1 and current), so a regression like this class of bug should be caught before release.
No notebook code changes needed — none of the demos pass
method=explicitly, and 0.3.6's default ("lazy_precompute") is picked up automatically.Test plan
