"Signed claim-free DENY normalization receipt supplies existing producer-evaluated native act and approval-free digest before issue, never permission; requester consumer independently authenticates it",
"Actual retained registry normalization is source-owned and number-preserving; final join compares the approved act/PDP digest and refuses drift instead of refreshing old context",
"Original and newly fetched facts are validated separately; no mutation of original claim/context or either request digest",
"Exact immutable operation deadline must fit caller, original/fetched freshness and approval validity; decision is precise post-evaluation NotBefore to exact operation deadline",
"Entire remaining interval must cover declared backendTTL plus 5-second cleanup reserve and source maximum 120; this review does not approve that policy or native budget",
"Default Approval freshness 30 cannot satisfy minimum 30+5; fixture freshness 120 is explicit synthetic configuration, not a producer default flip or native grant"
