Subject: [PATCH] Phase 0: Gate A' green -- the shipping configuration is the
 spec

Static lib + OoT-only + Release together: 19/19 identical plus the
vanilla-then-MQ pair. Flags verified from the generated cache rather than
assumed, so Phase 2's CMake block and TorchExtract.cpp can be
transcriptions of this build and RunOnce respectively.

Archive bytes turn out to be configuration-independent -- the pair
produced exactly the sizes the Debug static-lib run did, phases=1450 on
both runs. Extraction 11.8s mean, so the static-lib wrapper costs nothing
over Gate C.

Confirms both Phase 2 dependency risks in the configuration that actually
ships: zlib fetched with BUILD_STORMLIB=OFF and no zlib.h includes,
tinyxml2 fetched with BUILD_NAUDIO=OFF removing its only consumers. Both
FetchContent declarations are unconditional.

+
+The shipping configuration, all variables at once. **19/19 identical**, plus the pair run
+**PASS/PASS**. Verified as genuinely that combination, not assumed:
+
+```
+USE_STANDALONE=OFF   CMAKE_BUILD_TYPE=Release   BUILD_OOT=ON   PORT_VERSION_ENDIANNESS=ON
+BUILD_{SM64,MK64,SF64,PM64,FZERO,BK64,MARIO_ARTIST,NAUDIO}=OFF   BUILD_UI=OFF
+BUILD_STORMLIB=OFF   ROM_CRC_BSWAP=OFF
+```
+
+**That flag set is now the spec.** Phase 2's root-`CMakeLists.txt` block is a transcription of it
+and `main.cpp`'s `RunOnce` a transcription into `TorchExtract.cpp` — copy, don't re-derive.
+
+- **libgfxd is absent here too**, in the exact combination that ships: `_deps/` holds only
+  tinyxml2, yaml-cpp and zlib. The Binary export path is gfxd-free under Release as well as Debug.
+- **Archive bytes are configuration-independent.** The pair produced 33,154,599 (`pal_gc`) and
+  33,120,244 (`pal_mq`) — identical to the Debug static-lib run in Gate A2, and both runs reported
+  `phases=1450` including the second. Debug/Release and CLI/static-lib all agree.
+- **Extraction: 11.8 s mean per ROM**, matching Gate C's Release number. The static-lib wrapper
+  costs nothing.
+
+**Both Phase 2 dependency risks are now confirmed in the shipping configuration, not merely
+predicted:**
+
+- **zlib is fetched** under `USE_STANDALONE=OFF` + `BUILD_STORMLIB=OFF` despite zero `zlib.h`
+  includes in `torch/src` (risk #1).
+- **tinyxml2 is fetched** even though `BUILD_NAUDIO=OFF` removes its only Torch consumers — the
+  `FetchContent_Declare(... OVERRIDE_FIND_PACKAGE)` is unconditional, so it will hijack
+  libultraship's `find_package(tinyxml2 REQUIRED)` regardless.
+
+Neither affects archive bytes; both are link/configure concerns for Phase 2, and both are now
+observed facts rather than readings of the CMake.
