Proposals / #707

Type the Windows path hash lookups as context-to-node operations

rejected · by Commit-Will · submitted 2026-11-01, rejected 2026-11-01

Win 0067ae00/0067ae50 receive the existing D2DrlgPathSearchCtxStrc pointer and return D2DrlgPathNodeStrc* or null, currently int32_t input and short* return. Complete 74/78-byte bodies index context buckets at +0/+512, compare the node coordinate words and follow its +48 node link; normal EAX values are only a bucket/linked node or explicit zero. Independent complete insertion/pop bodies write actual pool-node pointers to those bucket heads and links. All references are audited: each lookup has one call in 0067b200, whose context comes through all eight 0067b440 calls from the exact 13036-byte frame object in 0067b850. Restore input and return together, preserving nOpenListBase, uint32_t nPackedPos, two dword stack slots, stdcall RET8 and all locals. Existing context/node layouts, full callers/producers and original Windows bytes independently prove identity. No pending allocator metadata, custom ABI, shared type, Mac pair or runtime change is relied on.
