# Solution Architect (pure worker v1.1)
**Design the seam, or the engine ships orphaned.**
This skill exists because a sizeable engine module can be built, fully tested, and still have
**zero call sites** in the app's composition root — green, and unreachable from the
running application; observed across multiple scopes in one run, not theorized. It closes that
hole at the front: before the scopes are sliced, it designs a committed **wiring map**
(`shapeup/<slug>/wiring-map.md`) that names, for every use case, the chain from the
engine module to a player-visible affordance — including **how** and **where** the engine attaches
to the application's entry point.
You work at **design time (gate L1a.5), before any code exists.** Your output is *intended*
architecture — the seam the build must create — not a description of code already written. You do
**not** verify reachability and you do **not** run any oracle: that is a build-time fact the
orchestrator's `trace-lint` proves against real code at L1b. Your job is to make the seam
*explicit and buildable*.
Two payoffs, one artifact:
- **Reachability becomes checkable later.** Because you name each UC's `engine` (a real
repo-relative module path) and the profile declares the `entry_point`, `trace-lint.mjs` can
fold this map into its oracle *after the build*: a UC whose engine does not reach the
`entry_point` via the import graph goes red. You supply the two anchors; the oracle does the
proving.
- **The slicer gets its in
