test: gate-running interop test for null-fill Sparse and null-run RunEnd (#233)#240
Merged
Conversation
…End (#233) Four JNI-written fixtures verify that the #225/#226 validity fixes hold on every gate run, not just the weekly Raincloud conformance sweep: - jniNullFillSparse_f64_nullRowsDecodeNull: ~98% null column, JNI chooses vortex.sparse with null fill; every unpatched row must decode as null. - jniNullFillSparse_i64_nullRowsDecodeNull: same shape for i64 (nuclear_share_energy). - jniNullRunRunEnd_i16_nullRowsDecodeNull: i16 null/value runs, JNI picks vortex.runend; null runs must decode as null, not the FoR base. - jniNullRunRunEnd_i64_nullRowsDecodeNull: same for i64. The encoding assertions are hard-coded (JNI version is pinned); a future JNI bump that changes the choice should refresh the fixture. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Summary
Four JNI-written fixtures that reproduce the #225 (null-run RunEnd) and #226 (null-fill Sparse) shapes on every
verifygate, not just the weekly Raincloud conformance sweep. A validity regression now reddens the per-PR CI run rather than surfacing a week later.Test fixtures
