Live-tested in Durotar after the herb/ore categorization fix merged
and rebuilt: spawned Mageroyal almost exclusively, which is not in
Durotar's configured pool (verified the live config is correct and
uncorrupted -- Peacebloom/Silverleaf/Earthroot/Copper Vein). No ore
appeared either, despite Copper Vein being in the list and containing
the word 'vein' -- which should have matched even the pre-PR-#7
keyword heuristic, suggesting this isn't purely a categorization
issue.
Hypothesis: herb/ore pool building may now filter against the full
set of IDs the lookup table knows about, rather than the current
site's own configured entries. Flagged for direct verification against
the merged code rather than assumed.
