docs/04-real-render-walls: SESSION 131 section 10 - the utility ring lives in vidmem (map PA 0xa0000, live entry 0x120100000/40) and the decoded 14-entry LID ring is a STALE page from a dead session, which is why its payload chunks read zero through every path (four reads + BO poller + gdb write-watchpoint); the CUDA contrast proves the LID arm works with real contiguous payloads; next step is reading the live ring through the map and decoding its entries
