Each pfSellData entry was a "sell,buy" string. The sell price duplicates
what C_Item.GetItemSellPriceByID returns from the engine's item DBC, so
it's redundant in our table — only the buy price (curated from real
vendor encounters, not a static item property) needs to live here.
Transformed every [id]="X,Y" entry across env/tables.lua, compat/tbc.lua,
and modules/turtle-wow.lua to [id]=Y via sed. Format is now itemid →
buyPrice (number, copper).
sellvalue.lua: reads sell from C_Item.GetItemSellPriceByID(id), reads
buy from pfSellData[id]. Items that have only a sell price (not in
pfSellData) now display sell-only — previously they got no tooltip
addition because the lookup gated on table membership. Items with
buy-only (sell == 0 in old data) still display buy correctly.
autovendor.lua: replaces the pfSellData[id] gate (which only checked
table membership and unused the parsed sell/buy) with a direct
C_Item.GetItemSellPriceByID > 0 check — the engine's canonical
"is this item sellable to a vendor" answer.
env/tables.lua — Updated pfMapOverlayData to current Turtle WoW WorldMapOverlay.dbc (53 zones, 707 overlays — added 12 new zones, ~40 new exploration areas)
modules/mapreveal.lua — Use separate texture pool to prevent conflicts with Blizzard overlay rendering; removed legacy errata and unused hash logic
