A pruned node in miniature: fetch a window of at most 6 raw mainnet blocks, decode them byte-exactly, and run the full stacked rulesets — header, transaction, block, block-context — while evolving a UTXO window. Rules whose context was pruned away are skipped and say so; that is the pruning tradeoff. Script/signature execution is out of scope. · schema · headers · spv · tx
