| Scope | Topic cycle only |
| Prerequisite | Delivered `lulu-approach` as a `decision-package` |
| Output | Delivered arch doc |
| Ownership | `lulu-arch` prepares stage inputs; `compose` owns orchestration |

- established `$CYCLE_ID` and `$CYCLE_TYPE` via `## Session Foundation`
- set `$SKILL_DIR` = `$SKILL_ROOT/lulu-arch`
</HARD-GATE>
