cad-milestonelisted

<objective> Close a finished milestone and set up the next. Thin by design - it collapses new-milestone + complete-milestone + cleanup into one flow. It tags the release only when the project tags (non-release projects skip it), it never ships (publishing a tag is /cad-land's call), and it never cuts a milestone that silently dropped a requirement (cad-audit gates it). </objective> <execution_context> @${CLAUDE_PLUGIN_ROOT}/cadence-core/workflows/milestone.md @${CLAUDE_PLUGIN_ROOT}/cadence-core/references/git-guard.md </execution_context> <process> Run the milestone workflow end-to-end. The audit gate is real - do not tag a milestone with a failing traceability audit unless the user explicitly overrides. Prune from the working tree only (git keeps the history); never auto-push the tag. Under `git.auto_close` (default off), chain into `/cad-land` to complete the close (PR -> merge -> reset), still halting on a surviving blocker/high `risk_surface` finding; otherwise stop at the tag and leave publishing to a separate `/cad-land`. </process>
