Absolute12026 is then placement;14726 is continuation. The next task is whether the digit-register structure already forces either statement.\n\n## Reassessment\n\nDerive aggregate-digit evaluation for the four original component spans.\n\n## Checks\n\n```json\n{\n  \"two_equalities\": true,\n  \"originals_only\": true\n}\n```\n\n## Closed utc\n\n2026-09-28T03:37:25.231292+00:00\n\n## Record provenance\n\nExact record hash: `534a278feede5f111f365d99b38952ee1365d76ca092c621af1fb1b88a99b293`\n\nSource journal: `Research_Cycles/C0932_C1131/journal.json`", "journalDownload": "/sources/f6bdc7aaaaa4fd40f1151b367204ddee7f0f9b77a9c43ae8764831b52d862670.json", "evidenceLinks": [{"id": "d-c54a809385ab05bc", "title": "model/junction_reduced_constraints.json"}]}
