 "result": {
  "summary": "Adds unit tests in bech32_tests.cpp to verify Bech32m checksum error detection guarantees and error location bounds at both the standard 90-character limit and the 1023-character silent payments limit. Also adjusts comments in bech32.h to state that checksums detect character changes rather than ambiguously implying they can find or fix errors.",
  "problem": "Test coverage does not explicitly validate error detection guarantees or error location behavior around the 1023-character limit introduced for BIP352 silent payments. Furthermore, header comments stating that character limits 'guarantee finding up to N errors' can mislead developers into thinking errors can be accurately located or repaired.",
  "card": "This PR adds unit tests verifying Bech32m checksum error detection and error location bounds at both the standard 90-character limit and the 1023-character silent payments limit. It also clarifies comments in bech32.h that character limits guarantee detecting changes rather than locating or fixing errors. The change addresses missing test coverage for the BIP352 silent payment character limits.",
  "evidence": [
   "Author noted in the description: 'Initially I was just looking at all code around Silent Payments, looked if the bech32 test had been updated to have tests for the new CharLimit::SILENT_PAYMENTS, and saw less tests than I expected.' (PR description)"
