+- E1: business.test.mjs is an existing test file with a 4-line addition after the playground refusal.
+  The in-review request lists it next to survey.test:73.
+- E3 fixed: supportingPath now runs the string check before `JSON.stringify`, so a BigInt (or any
+  non-string) path refuses `library-write-story-path` instead of throwing a TypeError.
+  supporting.test's string case now covers 7, null, undefined, 1n and an array.
+- E2 open: `editor` takes surrounding whitespace, and git trims it at commit, so the saved ident and
+  the commit ident can differ. DESIGN.md section 1 says "non-empty after trim". Refusing
+  `value.trim() !== value` would change that approved rule, so it went to Sage instead of into the
+  build.
