PakEquivalenceTests runs MeshExtractor LIVE and bakes the SAME fixture
ids to a temp pak, reads it back via PakReader, and deep-compares every
field via the Task 3 ObjectMeshDataEquality comparator. Since the bake
tool and the live client drive the identical MeshExtractor code (MP1a),
this proves the pak ROUND-TRIP preserves what extraction actually
produces on real content — the serializer's job, not a re-verification
of the extraction algorithm itself (the existing Conformance suite owns
that).
Fixture set (>= the plan's minimums): 10 GfxObjs (3 known-tricky ids
reused from Issue119UpNullGfxObjDumpTests - 0x010002B4, 0x010008A8,
0x010014C3 - plus 7 more from dat order), 3 Setups reused from door/
tower conformance fixtures (0x020019FF, 0x020005D8, 0x020003F2), 5
EnvCells walked from the Holtburg landblock 0xA9B40000's
LandBlockInfo.NumCells range (same idiom as
StipplingSurfaceEquivalenceTests).
Skips cleanly when dats are absent via ContentConformanceDats.
ResolveDatDir(), a deliberate small duplicate of
ConformanceDats.ResolveDatDir()'s exact pattern (env var then
Documents/Asheron's Call fallback) since Content.Tests cannot reference
the AcDream.Core.Tests project. ContentTestDatCollectionAdapter is a
third small copy of the IDatReaderWriter dat-access glue (alongside
AcDream.App's internal original and AcDream.Bake's copy) for the same
layering reason (structure rule 6: tests live in the project matching
the layer under test).
Ran for real against the dats on this machine (not just CI-skip path):
1 test, all fixture ids extracted live with zero failures, baked,
read back, and field-for-field identical. Full solution dotnet test:
4106 tests total (43 Content.Tests + 385 Core.Net.Tests + 425
UI.Abstractions.Tests + 722 App.Tests incl. 2 pre-existing skips + 2531
Core.Tests incl. 2 pre-existing skips) — 0 failures.
New xunit test project for the Content layer (rule 6: tests live in the
project matching the layer under test). ProjectReference to
AcDream.Content; TreatWarningsAsErrors + LangVersion latest per MP1b's
csproj requirements. Registered in AcDream.slnx. Placeholder PakKeyTests
smoke test becomes the real Task 2 suite next.
