  "summary": "Adds a unit test to verify that SelectionResult::Merge preserves the automatic selection algorithm when merging manual preset inputs and automatic coin selection results. It checks that merging manual inputs into an automatic selection retains the automatic algorithm, and merging an automatic selection into a manual one adopts the automatic algorithm.",
  "problem": "Selection algorithm metadata retention in SelectionResult::Merge is not directly tested when combining preset MANUAL inputs with automatic selection results, risking unnoticed regressions in selection reporting.",
  "card": "Adds a unit test in coinselector_tests.cpp verifying that SelectionResult::Merge preserves the automatic coin selection algorithm when combining manual preset inputs with automatic selection results. Existing tests did not cover algorithm tracking across merges, leaving reporting behavior open to silent regressions. The author verified effectiveness via mutation testing showing both test cases fail if manual algorithm propagation is altered. This is a low-risk test-only change with no dependencies.",
  "evidence": [
   "Author notes that applying a mutation to the merge behavior causes both test cases to fail with 'manual != bnb' (PR description)"
