Found by n8n-mcp-tester agent: IF nodes in n8n store connections as:
IF.main[0] (true branch)
IF.main[1] (false branch)
NOT as IF.true and IF.false
Previous implementation (WRONG):
- branch='true' → sourceOutput='true'
Correct implementation (FIXED):
- branch='true' → sourceIndex=0, sourceOutput='main'
- branch='false' → sourceIndex=1, sourceOutput='main'
Changes:
- resolveSmartParameters(): branch now sets sourceIndex, not sourceOutput
- Type definition comments updated to reflect correct mapping
- All unit tests fixed to expect connections under 'main' with correct indices
- All 141 tests passing with correct behavior
This was caught by integration testing against real n8n API, not by unit tests.
