  "$comment": "publicationGeneration must exactly equal runtimeOwnerGenerations[String(pid)] in the relevant stable owner vector from codex-prompt-publication-state-v2. runtimeRegistryGenerations is validated structurally but is not a receipt-freshness key. Receipt bytes are immutable for one publicationGeneration; every publication, replacement, or tombstone requires a fresh owner generation. processStartIdentity must equal the lowercase kern.bootsessionuuid plus the exact Darwin proc_pidinfo(PROC_PIDTBSDINFO) start tuple before and after snapshot validation, and the complete represented PID-to-identity set must still match during final batch verification. Receipt bytes and publication generations are reread byte-exactly before aggregation. catalogFile must contain the same PID as pid and the raw SHA-256 hex from catalogHash. The immutable snapshot uses codex-prompt-catalog-v1.schema.json."
