Dismissed audit patterns

This section captures the reasoning behind ai-audit findings that have been closed as "not planned". Before opening a new audit finding (or reporting an existing concern), check whether it falls under one of these patterns — the rationale has already been considered and rejected. Cite the canonical issue when relevant.

For dismissals newer than this section, also consult: gh issue list --repo zeroc-ice/ice --label ai-audit --state closed --search "reason:not-planned".

1. Slice loader cache pins generated-code assemblies (C#)

AssemblySliceLoaderFactory (csharp/src/Ice/Internal/AssemblySliceLoader.cs) caches the Slice loader it builds for each assembly marked with SliceAttribute — and, through its recursive merge, for every marked assembly it references — in a process-wide cache holding strong references. Unloading such assemblies (e.g. with a collectible AssemblyLoadContext) is unsupported: the cache pins them for the lifetime of the process. Assemblies without the attribute are never cached. Don't file findings proposing weak-key caching or unload-safety for this cache. Same disposition as icerpc/icerpc-csharp#4827. (#6658.)
