They must be operationally available but need not be independent source inputs. This refines C909 and improves compression without weakening the whole-field results.\n\n## Reassessment\n\nMap each tested family to the shared operations and retained source choices.\n\n## Checks\n\n```json\n{\n  \"five_domains\": true,\n  \"decimal_derived\": true,\n  \"no_primitive_digit_claim\": true\n}\n```\n\n## Closed utc\n\n2026-09-28T02:58:38.545782+00:00\n\n## Record provenance\n\nExact record hash: `4ab6cac0252a459b3e05460b8986cef90a0d153636941d38ab7757c31f21495c`\n\nSource journal: `Research_Cycles/C0832_C0931/journal.json`", "journalDownload": "/sources/6a37be4e218f9f467cbde5e9db3723ce9c79dc78cc97d1a289422b96cb9971e0.json", "evidenceLinks": [{"id": "d-7bdb0d544439654c", "title": "model/primitive_vs_derived_state.json"}]}
