Thread Safety: - Add lock to BTreeIndex (insert/get/scan/remove/contains) - Add lock to InvertedIndex (addDocument/removeDocument/search/bm25/tfidf/fuzzy/regex) - Add ctxLock to ExecutionContext for DDL/schema metadata, autoIncCounters, sequences - Deep-copy sessionVars in cloneForConnection() to isolate per-connection state - Fix activeConnections check-then-act race with Lock Wire Protocol Hardening: - Fix RangeDefect in deserializeValue for invalid FieldKind bytes - Fix IndexDefect in fkFloat32/fkFloat64 by reusing readUint32/readUint64 - Fix int32/int64 cast from uint32/uint64 to use cast[] instead of constructor - Fix parseHeader to validate MsgKind instead of holey enum cast Property-Based Tests (tests/prop_test.nim): - 8 invariants for evalExprValue: literal types, commutativity, identity, double negation, NULL propagation Wire Protocol Fuzz (tests/fuzz_test.nim): - 7 fuzz tests: random bytes deserialization, truncated buffers, MsgKind casts, parseHeader logic, message roundtrips NimForum Adapter Smoke Test (tests/nimforum_smoke_test.nim): - Full TCP server lifecycle with adapter CRUD and parameterized queries Test Results: 423 tests pass, 0 failures
