Their summed length exceeds the continuous field union by660. This accounts for the resolution difference without treating summed intervals as one chronological distance.\n\n## Reassessment\n\nReconstruct every full-resolution weekly boundary and its companion convergence.\n\n## Checks\n\n```json\n{\n  \"overlaps\": true,\n  \"union_identity\": true\n}\n```\n\n## Closed utc\n\n2026-09-28T00:24:49.844082+00:00\n\n## Record provenance\n\nExact record hash: `085602267ad7de05bbfcdbefe99278778305f46be906b7d93acec1a9566176f3`\n\nSource journal: `Research_Cycles/C0532_C0631/journal.json`", "journalDownload": "/sources/7a2e1117efc741218b68e2db8bb20eadd33cab34e00384e9b903708031da1d2d.json", "evidenceLinks": [{"id": "d-2fb72e6c1267ac3e", "title": "File 68"}]}
