The completed journal retains a reassessment after every action. Forty-eight analytical steps received independent review; the final two consolidate review and synthesis. The next source-family test remains unexecuted.\n\n## Reassessment\n\nUse this draft as the shared big-picture account; if research continues, perform the proposed C532 bounded reconstruction without reopening already resolved audits.\n\n## Checks\n\n```json\n{\n  \"draft_exists\": true,\n  \"checkpoint_exists\": true,\n  \"operations_diagram\": true,\n  \"cross_family_table\": true,\n  \"reviews\": true,\n  \"scope\": true\n}\n```\n\n## Closed utc\n\n2026-09-27T23:02:04.929225+00:00\n\n## Record provenance\n\nExact record hash: `646c8bb822355b60f1110fbb059453a1f0ebfaf7294c715f338ca64cf2bf5216`\n\nSource journal: `Research_Cycles/C0482_C0531/journal.json`", "journalDownload": "/sources/6eaeccad4734eff2f6ac20ba847967877b944f9758c53c712ac8b5be2ddf61eb.json", "evidenceLinks": [{"id": "file52c", "title": "File 52c"}]}
