+# NOW -- Port gHashTag/trinity:src/cli/railway_deployment_create.zig (Zig, 1 function) to specs/port/trinity/src/cli/railway_deployment_create.t27 (published 2026-10-06)

+## A bee's work on #6108, published from `queen-6108` (Closes #6108)
+
+- The branch changes 1 file(s): `specs/port/trinity/src/cli/railway_deployment_create.t27`.
+- `git diff --stat origin/master...queen-6108` reads: 1 file changed, 197 insertions(+)
+- This entry is written by the publisher, not by the bee. A pull request must
+  add exactly one `docs/now/` entry and a bee has no way to know that: its brief
+  names a boundary file and acceptance criteria, and `docs/now/` is neither.
+- What this entry does NOT establish: that the work is correct. The gates on the
+  pull request judge that, and they are the same gates every other change meets.
