The WeenieHeader fixed prefix plus the ~300-line conditional
optional-tail cascade moves verbatim from CreateObject.TryParse into
PublicWeenieDescParser.Parse (PublicWeenieDescBody.cs), so Slice 5.1's
vendor-item parser can share it instead of duplicating it — each shop
item on the wire is a full CreateObject-style PublicWeenieDesc
(research doc §A.2). Same field order, same nested try/catch swallow
shape, same truncation messages; CreateObject composes its Parsed from
the returned record. Zero test files changed; Core.Net tests 764/0/0
unchanged; clean-room complete solution 11,271 passed / 4 skipped / 0
failed.
Per the Slice 5 contract (decision 2): extraction FIRST, as its own
bisectable commit, before any vendor code exists to call it.
