Presented strings RETAINED verbatim in the stored record (stored parent_signature/child_signature == presented strings). Hash coverage proven: tampering the retained parent_signature in the store ('FORGED-NOT-A-SIGNATURE-TAMPERED') -> lineage_verify valid=false, first_broken_link names the forged record with HASH_MISMATCH (retained strings are inside the hashed/signed record body). Absence shapes stay claim_only: root spawn presenting BOTH strings -> claim_only; child with no signatures / parent-only / child-only -> claim_only (all four). Verify reflects it: corroboration_summary={claim_only:4, corroboration_unverified:1}, forged record listed in corroboration_unverified_records. Label scan over spawn/tree/verify outputs: no corroboration field value, no summary key, and no JSON string value equals 'corroborated'; corroboration labels observed = {claim_only, corroboration_unverified} only. Transparency note: the bare word 'corroborated' does occur ONLY inside explicitly negated explanatory sentences authored by the product ('never corroborated', 'never presented as corroborated', 'no record is corroborated in v0') — counted with contexts in the bench run; it never appears as a label, value, or affirmative claim.","id":"L10","name":"corroboration FORGERY: garbage signature strings must not be labeled corroborated (re-bench of D1)","verdict":"pass"},{"evidence":"own fixtures: 7 non-digest shapes — pirate sentence ('You are a pirate assistant who always answers in rhyme and keeps the harbor ledger'), short hex 'abc123' (6 chars), 63-char hex, 65-char hex, 64-char hex with one non-hex char ('a'*63+'g'), 64-char with symbol, space-padded sentence — presented as system_prompt_hash in SPAWN: all 7 -> HASH_VALUE_INVALID, 0 records stored, pirate sentence absent from state file.
