The task is already complete. All 4 sections of index.md are properly updated:

1. Pages Table (line 62): [[MarkSweep-GC]] entry added
2. Concepts → Pages (lines 192-193): Both "MarkSweep GC" and "MarkSweep" entries
3. Source Path → Pages (lines 272, 292-293): Memory manager paths mapped to MarkSweep-GC
4. Task Routing (line 365): GC development category includes MarkSweep-GC

The Glossary already contains MMTk definition (line 44) which references MarkSweep. The wiki page was created and the issue was closed.
