Refs #5
Replace the hand-built Case 7 payload assertion with a temporary
production-source guard. The test now fails if Step 9 stops emitting
candidate_evidence, breaks the fallback_chain compat alias, or removes
the alias intent comment.
This is intentionally temporary because Step 9 application-plan unit
assembly is inline. Follow-up IMP-32 should extract a helper and replace
this source-string guard with a direct helper test.
