candidate_count	Distribution of valid candidate counts per sample.
rri	Distribution of finite oracle RRI values across sampled candidates.
vin_points	Distribution of VIN point lengths across sampled snippets.
numeric_bytes	Approximate bytes occupied by manifest-declared numeric shard blocks.
block_shapes	Stored numeric block shapes keyed by logical block name.
block_diagnostics	Manifest-declared block diagnostics for Streamlit and CLI tables.
