Adds a dated accounting to the XSTS deviation worklist: the labelled-suite
ratchet stands at 0/74/0/133 with false positives held at 0 across the campaign.
Partitions the remaining 74 into fixable-but-intricate debt (redefine
restriction, NameAndTypeOK union membership, wildcard UPA, chameleon/cross-ns
composition, heterogeneous particle edges) and irreducible-by-design or disclosed
items (RecurseAsIfGroup spec ambiguities, the deliberate regex-tolerance), with
the root cause and false-positive risk for each so the burndown is driven by
understanding. Records that the adversarial critic loop caught three genuine
false positives this session that the suite and differential both missed.
