+
+Node v26.8.1. refactor was e2b873390 (226 landed); `git diff --stat 45dca69f6 e2b873390 -- packages/library
+packages/business` is empty. TMPDIR was a mktemp -d under /mnt/storage/scratch/tmp, with pipefail.
+Singles and mutants ran under `timeout -k 10 600`, suites under `timeout -k 10 1800`.
+
+First-run red (mos-1272, placed): the first base run on 46bad7ea3 at 20:01:09Z was red in
+supporting.test "malformed paths refuse by class, in order". 5 of 6 passed, with `TypeError: Do not know
+how to serialize a BigInt`. The cause was the test helper, not the product: `refuses()` labelled each
+assertion with `JSON.stringify(path)`, and the 1n case added for E3 can't be stringified. In c18ad3e12
+the label uses `util.inspect(path)`, a 2-line test-only change. The product's 1n refusal was never in
+question: supportingPath type-checks before it stringifies (E3). The whole run below is on c18ad3e12.
+
+Base, the touched files whole (20:01:43Z), all rc=0:
+- library mapping.test 16/16, scope.test 6/6, supporting.test 6/6, survey.test 7/7;

+- 0 skipped, 0 cancelled, 0 todo.

+Mutants (20:01:44Z). Each was applied by exact string with count 1, then restored with `git checkout --`.
+Every restored sha256 equals HEAD's blob, and the tree was clean after.

+## 2026-10-23 G1: mos-1528 OK for the mapping.test draft deepEqual (sage-3713)
+
+This entry completes the N3 line above (BUILD.md:42, "only the draft deepEqual at mapping.test:48 gains
+`supporting: []`"). BUILD.md is append-only, so :42 stays as written. Mos OK'd the change of that old
+assertion in mos-1528. It is now at packages/library/tests/mapping.test.mjs:52, and commit 331653b38
+changed it. Everything else in that commit's hunk is new test lines, not changed old ones.
+
+- Old, mapping.test.mjs:48 at 45dca69f6:
+  `assert.deepEqual(m.universes.idea, { kind: 'draft', name: 'New World', books: [], playground: ['Drafts/New World/'] });`
+- New, mapping.test.mjs:52 at b2a1f4092:
+  `assert.deepEqual(m.universes.idea, { kind: 'draft', name: 'New World', books: [], playground: ['Drafts/New World/'], supporting: [] });`
+
+The line gains only `, supporting: []`; nothing else in it moved. The business.test and scope.test hunks
+add tests only (sage-3713: no OK needed). The other old-test change in this row is survey.test:73
+(mos-1330 item 4, 28918824c). Doc only.
