+"""Customer Mission #4 — a second, different contract target (no tender-special-logic).
+
+Pins what Mission #4 guards: TWO structurally different contract sub-types (a public tender and a
+private OEM Lastenheft) run through the identical engine and produce DIFFERENT, non-overlapping deltas
+with no per-contract code. That is the evidence that the later Scope→Journey selector can treat any
+contract as a plain Required set — no tender-shaped special case baked in.
