+## Addendum: 2a758a5ba (Bushroot, 17:15Z, parent 435b7b559)
+
+Read with git, nothing run. Four files: stack-release.sh, stack-release.test.mjs, the webui README and
+BUILD.md.
+
+- B1 met. `console_for_target` drops `--board` for every op, and `parses_flag` now only picks the reason. A
+  pre-198 target says the 7331 board is retired and this Console runs without it. A post-198 target says the
+  board runs in the Console. The README paragraph covers activate and rollback, so N3 is met too.
+- B2 open. Both M13 tests (activate and rollback) still run `--plan` only. sage-2834 asked for an argv
+  assertion on the install. Add one real run, for example the rollback, asserting exit 0, the drop line in
+  the steps, and no `--board` in the installed Console unit.
+- B3 open. BUILD.md's table still has no `reply()` join mutant, and board.test.mjs is unchanged.
+
+Verdict stands: CHANGES, B2 and B3.
