 Duckworth approves DESIGN.md, then the manifest. Any repository change is green on Sage's gate (cli suite and
 every `scripts/test-*.sh`), with the design's mutants killed. The row is done when the window's acceptance
 run passes on .53, Duckworth reads its output, and Mos confirms.

+## Row 195 follow-up: Duckworth's N1-N3 on the Case 1 acceptance script
+
+Sage, 2026-10-21. Row 195's code landed as b65014647. Duckworth's manifest notes N1-N3 (REVIEW-m1 6afcee2a5)
+are recorded in docs/plans/DEFERRED.md (d6cff0cdd). Owner Darkwing, reviewer Duckworth, gate owner Sage.
+
+- N1: F9 runs the `--node` binary as root (`scripts/case1-accept.sh:298`) before F10 checks its path
+  (:303-304). Root must never run a binary the script hasn't checked yet: run F9's parse as `AS_USER`, or move
+  F10's path check ahead of it.
+- N2: the header (:10) and the TOOLS.md entry must list everything root runs, not just "reads".
+- N3: F6's prefix match (:261) must refuse a `--claude` path with `..` after `claude-<pin>/`.
+- Build on a new branch from the refactor tip, starting from Darkwing's `darkwing/row195-n1` 1e3c4767c. That
+  commit hasn't been run.
+
+Gate: Duckworth approves the manifest. The cli suite and every `scripts/test-*.sh` are green on Sage's gate,
+and a mutant for each of N1 and N3 is killed. This row lands before the .53 window row below.
+
+## Row 195 window: the Case 1 acceptance run on 10.1.1.53
+
+Sage, 2026-10-21. This row carries row 195's done condition from the Gate section above. Sage moved row 195
+to done at its code landing (rev 2790), which was early, and done rows can't change, so the condition
+continues here. Owner Darkwing, reviewer Duckworth, gate owner Sage. It waits on row 226 and on the N1-N3
+follow-up landing.
+
+The window needs a Jason or Mos go. It takes a backup first where state exists and gives a STATE report
+after. The Boundaries above apply unchanged.
