+- **A reviewer that wrote `printed: REVIEWED_TREE: …` is no longer failed.** Two readers in GBRA-218 echoed the command and then wrote the fingerprint after a `printed:` label, so /ship read no line, failed them and restarted the pass twice. The label is now read, plain, bold or inside the line's backticks, and the tree and checkout it names are still compared exactly. A wrong tree or checkout is still refused.
+- **The Capy pass program stops before it sends a reader into the wrong checkout.** Capy starts every shared reader in the thread's working directory and cannot start one anywhere else. In GBRA-218 an outside voice ignored its `cd` and reviewed that checkout, so Step 11 lost its outside coverage. Now, before a stage takes a start token or sends its first reader, the program compares that directory with the checkout /ship ships. It stops when they differ or the directory can't be read. **Run /ship in the thread's own checkout**, not in a worktree beside it. A start directory outside any checkout, such as a multi-repo workspace root, still dispatches.
+- **Step 11 takes the right start token.** Reusing the pass input's `logStart: ["review"]` for `stage: "voices"` used to run the voices with no `adversarial-review` start, which left Step 11.5 nothing to bind. Step 11 now takes `adversarial-review` by default and stops before anything runs when given any other list. The gstack Capy skill says Step 11 swaps `logStart` for `stage: "voices"`.
