authored gmSecureTradeUI window, and both retail open paths
Three-lane research first (docs/research/2026-08-14-trade-lane{A,B,C}):
retail gmSecureTradeUI decode, the byte-exact ACE/decomp/holtburger
three-way wire agreement, and the acdream seam map (which found both
open paths ALREADY classified by the ported policy - OpenSecureTrade on
Use-a-player, StartSecureTrade on drag-item-onto-player with the
DragItemOnPlayerOpensSecureTrade option - dead-ending at a stub toast).
- Core.Net: TradeRequests builders (0x1F6-0x204, retail's CM_Trade
senders byte-checked against ACE's readers; the ACE-discarded
AcceptTrade echo carries zero-count item lists - AD-94), corrected +
completed inbound parsers (0x1FD-0x208; the old AddToTrade parser
missed the SIDE dword, TradeFailure missed the reason), delegate-hole
registrars, six WorldSession sends. 10 golden-byte tests.
- Runtime: RuntimeTradeState, the third sibling J-owner (fellowship/
allegiance shape): session-scoped, clears at generation reset (new
stage Trade=14), staged teardown stage 11 (Identity/EntityObjects
shift 12/13, TeardownStageCount 14 - the FA2-era per-stage-flag test
caught the mapping exactly as designed), combined ownership ledger,
event routing with ACE's wrong-initiator RegisterTrade landmine
honored (partner = whichever guid is not mine). 7 conformance tests.
- App: SecureTradeUiController binds the dedicated authored LayoutDesc
0x2100000D (root 0x1000007A - gmSecureTradeUI::PostInit's exact ids):
partner name/status/count/grid, the authored 'Trade' accept toggle
(accept <-> decline withdraw), 'Clear All' (ACE clears BOTH sides -
surfaced honestly), the X close, drop-on-your-grid staging, per-mode
accept cues (partner icon's authored Highlight state + Trade button
Selected latch). Mounted via the vendor recipe (nine-slice chrome,
hidden until RegisterTrade). ItemInteractionController's two policy
arms now raise SecureTradeRequested instead of the stub toast; the
drag path queues the dragged item until the window registers
(ClientTradeSystem::AttemptToTradeItem @0x0056DF80's shape).
Register: AD-94 (accept-echo zero-count lists), AD-95 (numeric-only
count texts pending template verification).
Suites: App 4,990/3, Core.Net 905, Runtime 1,626 - all green. The
panel itself is user-gate acceptance (two-client connected trade), the
#372-class lesson: fixture-green alone is not acceptance for a mount.
