+Amendment 1 (Mos mos-1580, 2026-10-24, after the r3 gate went red on row 323's
+`case1-business-file.test.mjs`). Row 323's Case 1 document
+(`docs/guides/case1-business.mosaic-stack.json`) has no library and no credentials. The exact-match rule at
+`business.mjs:51` would make every business's chief carry a gitea reference it never uses. Q247
+(`docs/plans/2026-10-23_optional-tracker-brief.md`) made the tracker optional because a business without one
+should carry nothing it doesn't use. The same reasoning extends to the library. So:
+- The chief's gitea reference is required only when the business declares a library. A business with no
+  library validates with chief credentials `{}`.
+- A business that declares a library but has no chief gitea reference refuses with a named message.
+- A business with no library and a chief gitea reference also refuses, so "exactly" still holds.
+- Every other role keeps the exact-match rule unchanged.
+- Row 323's document and `case1-business-file.test.mjs` stay byte-identical. No old test changes for this
