Decision: Delete old files entirely. No redirect stubs. Clean break. Rationale: GitHub wiki doesn't support redirects. Stubs add maintenance burden. Users on 0.9.30 should find the correct pages via sidebar navigation.

Decision: Leave all security warnings for Phase 4. Rationale: Phase 2 focuses on API accuracy (compile-breaking code samples, dead features). Security caveats (TripleDES, SHA256 password hash, hardcoded API keys) are fully handled in Phase 4 when those pages are the primary focus.

Decision: Minimal inline snippets + links to DotNetWorkQueue.Samples repo (decided during brainstorming).

Decision: All pages updated in Phase 2 must state .NET 10.0 / .NET 8.0 only. Remove all net48/netstandard2.0 references.
