</objective>
<context>
Phase number: $ARGUMENTS — optional; when omitted, the orchestrating workflow reads ROADMAP.md and selects the next unplanned phase. This is not a `gsd-tools.cjs` CLI feature — the CLI's phase-lookup primitives require an explicit phase number.
</context>
<process>
Execute end-to-end.
Preserve all workflow gates.
