and [trade] seam probes
- Use on a selected player did nothing: the world Use path
(SelectionInteractionController.RequestUse) dispatches 0x0036 directly
and NEVER consults DetermineUseResult - lane C's "both paths already
classified" claim described the POLICY's capability, not a live
caller (the verify-subagent-claims lesson, again). Retail's
CPlayerSystem::UsingItem @0x00562F70 consults it and routes result 5
(another PLAYER) to AttemptToOpenTradeNegotiations @0x0056DEE0, peace
mode only, with no Use send. Ported as
ItemInteractionController.TryOpenSecureTradeWithPlayer, called at
RequestUse entry.
- The broken window: both grids rendered their raw authored strip art
with no cell layout (the gold-ring tile was the naked track). They now
get the vendor strips' exact single-row 32px config + the authored
empty-slot art resolved through ItemListCellTemplate (cell-template
attr 0x1000000E -> 0x1000033A).
- Drag-onto-player "nothing happens": the policy chain reads correct
end-to-end in code (pick -> PlaceIn3D -> StartSecureTrade -> event ->
cmd), so TEMPORARY [trade] probe lines now bracket every seam
(drag-release pick, policy arm, controller request, use-on-player) -
the next gate log pinpoints the break if it persists. Stripped once
the two-client gate passes.
App suite 4,990/3 skips.
