Validation
Publication requires three independent gates:
construction_strict_pass=truefromscripts/36_validate_construction_v0_3.py.sft_ready=truefromscripts/33_validate_sft_readiness.py.publication_strict_pass=truefromscripts/38_validate_public_release.py.
All reports must have fatal_errors=[]. Upload is additionally blocked unless the expected pre-upload SHA matches. Revision-locked remote verification tests all seven configs and both splits.
