- Tooling/DataFlowClassifier: buckets a resolved selection via Roslyn
DataFlowAnalysis. Selection flow + tail flow (statements AFTER the
selection in the same block) both use the two-argument AnalyzeDataFlow
overload on the contiguous run; the em 01 spike verdict is pinned in
tests — a synthetic BlockSyntax (parent decision #3) throws
ArgumentException "statements not within tree" and would re-bind
symbols, breaking the written-inside ∩ read-after identity match.
- Buckets per parent spec as plain-string records: in-params = local +
parameter reads (filtering the implicit `this`; fields/properties stay
in the em 03 extract-first bucket), ByRef = reassigned inside via a
non-declaration write (declaration initializers are not write-backs),
returns = written ∧ read-after (tail, branch-insensitive
over-approximation) + trailing `return X;` simple-name candidate,
locals = written ∧ never read-after.
- CLI now prints the raw bucket dump after the statement count line;
classification failures exit 1 with a clean message (exit 0/1/2
contract preserved).
- Tests: 6 new (in-param incl. `this` non-leak, multi-statement
two-argument path, trailing-return, ref-vs-in differential, extract-first
non-leak, synthetic-block dead path, single-statement one-argument path);
shared DemoFixture loader; fixed pre-existing CS8602 in DemoFixtureTests.
36/36 green.
