Lamech is a separate −24 lifespan change with begetting182 fixed. One source row structure therefore produces two different chronological projections.\n\n## Reassessment\n\nApply the same row accounting to SP, including its completed-year boundary.\n\n## Checks\n\n```json\n{\n  \"six_repartitions\": true,\n  \"regular600\": true,\n  \"cumulative_minus24\": true\n}\n```\n\n## Closed utc\n\n2026-09-27T22:38:31.326136+00:00\n\n## Record provenance\n\nExact record hash: `934f0c51380606bedec92a8a87e13b5ef21fa6a726ba4fde385bb0948e79a0ae`\n\nSource journal: `Research_Cycles/C0482_C0531/journal.json`", "journalDownload": "/sources/6eaeccad4734eff2f6ac20ba847967877b944f9758c53c712ac8b5be2ddf61eb.json", "evidenceLinks": [{"id": "d-68301ab760bfbe2e", "title": "File 18"}]}
