Moving only the earlier endpoint adds the chosen3 or3.5 branch offset, giving273 or273.5; moving both preserves270. Thus the repeated value is source-order conservation, while the companion depends on the stated phase display.\n\n## Reassessment\n\nTest how the chronology joins imported census scalars without claiming a new census derivation.\n\n## Checks\n\n```json\n{\n  \"windows\": true,\n  \"exact_phase\": true\n}\n```\n\n## Closed utc\n\n2026-09-28T00:05:08.720278+00:00\n\n## Record provenance\n\nExact record hash: `2800211fe588a17377d317b74aa0516ee17a33e648d21fa89ec852ffe72413ef`\n\nSource journal: `Research_Cycles/C0532_C0631/journal.json`", "journalDownload": "/sources/7a2e1117efc741218b68e2db8bb20eadd33cab34e00384e9b903708031da1d2d.json", "evidenceLinks": [{"id": "d-12a48221b7fdcdcd", "title": "File 60"}]}
