queue: open Q80 -- spark's 48bdc86 validates one read and hashes another (1 divergence measured in 400 raced runs), reads NaN and Infinity as VALID against RFC 8259 6, drops duplicate keys silently, exits 1 for an unreadable input in the same class as a bad document, and lands 128 inserted lines across two commits without moving spark/CHECK; index re-rendered in this commit

 **What this is.** One row per `## ` section of `WORK-QUEUE.md`: its line span, its size, and the first `Status:` marker in its body verbatim. Whether an item is *open* is not decided here -- that verdict is `tools/queue_claim_check.py`'s, and this document does not overrule it.
 
-**What it exposes.** The queue is two-tier. 72 sections carry 66 ids because 6 ids own a second, continuation section. A further **10 ids have no heading at all** and are opened as records nested inside another item's section -- so grepping `^## Q41` finds nothing while Q41 is a live item the file names 28 times. Those are listed in their own table below.
