+# Row 303 (R9 guard, #1810, Vikunja 589) round 1: diff review (duckworth-0260)
+
+Reviewer: Duckworth. Builder: Launchpad. Requests: sage-3259, launchpad-0089.
+Brief: docs/plans/2026-10-23_r9-guard-row.md (ad6ca7930). Ruling: mos-1422 point 2.
+Candidate: launchpad/row303 at 88ffecaf7, one commit on 80793d824. Manifest digest
+3c3be5d36a57f60b85b58a8805a540bda548c300b537d1ecdf30714fb3d167b9, one path.
+Method: git reads only. No node, no tests.
+
+## Verdict: APPROVE, with C1
+
+- `git diff 80793d824 88ffecaf7 -- packages` is one added line in R9, between the exit-code check and
+  the `includes` check that builds `join(r.dir,'placeholders')`:
+  `+ assert.ok(r.dir!==null, r.out+r.err);`
+  It matches the brief character for character, with R9's one-space indent. No line is removed or
+  changed, and no other test is touched.
+- Beyond that line, the commit adds only the packet: queue-303/BUILD.md and MANIFEST.sha256.
+- MANIFEST.sha256 has one line, stack-release.test.mjs e936808b…cc33. That equals the blob at
+  88ffecaf7, and the file's sha256 is the stated digest 3c3be5d3…67b9.
+- rehearse() (:2039-2040) returns `dir:null` when the output has no `rehearsal directory:` line, so
+  the guard fires in exactly the case the brief describes, and its message carries r.out and r.err.
+- The template lines the brief names get no guard. After the insert, those below :2178 sit one line
+  lower (:2268 and :2281).
+- Drift: 80793d824 is an ancestor of origin/refactor 15e688cc0. Between them only two log files
+  changed (docs/SESSIONS.md and BUILD-LOG.md), nothing under packages/ or scripts/.
+- No test pins a hash of stack-release.test.mjs. The other references to it are comments.
+
+## Condition
+
+- **C1.** stack-release.test.mjs runs whole and green on Sage's gate, in a gap (the brief's Gate).
