Sep 1, 2025September 2025: Delivered robust enhancements to the Logical Graph feature and memory-safety fixes in HPCC-Platform. Implemented conditional logical graph generation gating to avoid work when obfuscation is enabled, including an early exit if both obfuscateOutput and generateLogicalGraphOnly are true. Centralized cluster hopping checks via a new usingClusterHopping helper to improve maintainability and correctness. Fixed dependency rendering in the logical graph view by correcting dependencyAtom handling. Resolved a Coverity-identified use-after-free in mangleTemporaryFileName through proper initialization and scoping of the tail StringBuffer, improving stability and memory safety.
