[counterintuitive] AI removes or 'fixes' platform-specific workarounds it doesn't understand

Flag comments containing 'workaround,' 'hack,' 'platform-specific,' 'don't remove,' or 'see issue' as protected code that AI must not modify without explicit human review. Build a registry of known workarounds and their rationales. Treat any code with an explanatory comment as radioactive for AI modification.

Journey Context:
Production code contains workarounds for platform bugs, hardware quirks, and undocumented behavior. These often look like mistakes: seemingly unnecessary null checks, redundant casts, or 'obviously' simplifiable logic. A senior engineer knows these workarounds exist for a reason and leaves them alone. AI sees 'obviously wrong' code and 'fixes' it, reintroducing the bug the workaround was addressing. This is catastrophic because the fix looks correct, passes tests \(which don't reproduce the platform-specific condition\), and the bug only manifests in production on specific hardware or OS combinations. The pattern: any code with comments explaining WHY something seemingly wrong is actually correct should be treated as protected. The deeper lesson: workarounds without explanatory comments are even more dangerous because AI will remove them silently. Always document workarounds.

environment: refactoring · tags: workarounds platform-specific defensive-code comment-preservation production-bugs · source: swarm · provenance: The fragility of workarounds during refactoring is a core theme in 'Working Effectively with Legacy Code' \(Feathers, 2004\)—specifically the concept of 'pinning points' and the danger of modifying code whose purpose isn't fully understood. Real-world examples are pervasive in systems code like the Linux kernel, where workarounds are marked with comments referencing specific hardware errata.
