Closed-form floors versus learned models in spatial omics: confirmatory protocol and registration package

Pre-registered confirmatory protocol for a benchmark of pre-specified closed-form floors against published learned models in five spatial-omics task families (cell identity, spatial domains, spatial context to receiver state, held-out cell-type counterfactuals, label transfer). Registered before any confirmation metric was computed, except the retrospective comparison with the authors' published Cellina and CPA results stated in the protocol. Contents: PROTOCOL.md (aim, hypotheses, families and comparators, data roles, analysis with margins and decision rules, power, tier-2 tuning-transfer and capacity diagnostic, deviation policy, compute, development history); spatialfloors-registration-v1.tar.gz (the full package: locked configurations, unit manifests with SHA-256 of every crop's cell-ID list, gene panels, the sealed confirmation job list, the code archive of the release commit and SHA256SUMS); SHA256SUMS. Verify: unpack, then shasum -a 256 -c SHA256SUMS inside registration/.
