# D50 verification, pass 2 (ledger-sourced tags vs primary data)

- OK   `published:essence_out_of_sequence` tagged 4 / recomputed 4 · skull: essence != wordlist[gan]; spooky/solstice: outside the longest in-order run
- OK   `chain:forge_pair` tagged 30 / recomputed 30 · every burnt piece has a forge record
- OK   `file:primes_missing` tagged 2 / recomputed 2 · primes 7..127 absent from the Photoshop 22.3 batch of 26 files (batch = exactly the other primes: True)
- OK   `file:psd_lineage` tagged 1 / recomputed 1 · the only file with an OriginalDocumentID and a real Photoshop document id in DerivedFrom
- OK   `file:negative_frames` tagged 4 / recomputed 4 · byte-level negative-frame detection not re-run here (kept as recorded)
- INFO `file:resave_sessions` tagged 86: save days of tagged [('2021-08-27', 26), ('2022-01-07', 16), ('2021-12-18', 14), ('2022-01-30', 13), ('2021-09-24', 4), ('2021-12-09', 3), ('2021-08-24', 2), ('2021-10-24', 2)] vs untagged [('2021-12-17', 73), ('2022-01-04', 55), ('2021-08-21', 52), ('2022-01-06', 50), ('2021-08-20', 48), ('2022-01-05', 30), ('2021-09-26', 22), ('2021-09-24', 20)]. Every file's XMP save time was decoded (UUID v1 in xmpMM:InstanceID); the session rule is not a simple day rule and stays as recorded.
- DIFF `number:prime_position_glitch` tagged 15 / recomputed 14 · extra [142] · robo positions that are prime and not Fibonacci (14). The tag carries 15: #142 sits at position 13, which is prime AND Fibonacci
- INFO hidden-type open question: #193 carries F at spooky position 0 (0 is Fibonacci under the letter scheme; F elsewhere marks robo binary palindromes). Tagged as palindrome, not as a misfile.
- INFO chain coverage: 14 pieces have no chain record [457, 458, 459, 460, 461, 462, 463, 464, 465, 466, 497, 498, 499, 500]; they are exactly the Review pieces whose sheet counter is binary or hex. Sheet-vs-chain tags cannot be evaluated for them.
- INFO sheet-vs-chain: 29 pieces differ on at least one field. Chain-side odd values (sheet value is the common one): [39, 48, 58, 62, 66, 88, 97]
- INFO sheet-side odd values: [17, 44, 73, 123, 128]
- INFO both-real-values (judgement): [4, 16, 47, 59, 62, 66, 73, 81, 100, 121, 124, 173, 175, 281, 309, 509]
