/**
 * Access planner — decides the best retrieval route for a candidate paper.
 *
 * Implements the routing logic from design-plan.md §5.2:
 * 1. Canonicalize identifier (prefer DOI)
 * 2. Infer publisher from DOI prefix / Crossref metadata
 * 3. Check local cache
 * 4. Check Zotero (if enabled)
 * 5. Check OA routes (OpenAlex, Unpaywall, Europe PMC)
 * 6. Evaluate publisher API routes (Elsevier, Springer OA, Wiley TDM)
 * 7. Evaluate browser routes
 * 8. Fall back to manual import
