swung0x48 901d48a678 [Fix] (MGPipe, Metrics, Config, CI): exchange the per-frame stats instead of racing a store, carry the three uncarried table entries, drop the inline host span from a buffer range, spell the buffer subdata range, and close the small gate holes 
- S-1 PipeStats::OnPresent read each frame accumulator and then store(0)'d it; a Bump from a staging thread landing in between was lost from the Tracy plot and from every frame. Each accumulator is now exchange(0, relaxed) and the exchanged value is what is plotted, so every add lands in exactly one frame.
- T-3 FdPassing without MSG_CMSG_CLOEXEC (macOS, BSD) handed back descriptors that survived exec; every received fd now gets FD_CLOEXEC by hand under !MSG_CMSG_CLOEXEC. MSG_NOSIGNAL is defined to 0 where the platform lacks it (FdPassing.cpp, Doorbell.cpp) and SO_NOSIGPIPE is set on the socketpair and on a SocketDoorbell's descriptor where it exists, so a write to a hung-up peer is EPIPE rather than a fatal signal.
- T-4 the missing-flatbuffers fallback wrote OFF into the cache with FORCE, so a plain re-configure after `git submodule update` stayed OFF silently. It is a normal-variable set now, shadowing the cache for that configure only; verified by hiding flatbuffers.h, configuring with ON (warning, transport off, cache still ON) and re-configuring plainly with the header back (transport ON).
- P-2 three LIVE GLFunctionsTable entries had no carrier: GetGpuTimestampNs (glGetInteger64v(GL_TIMESTAMP), a synchronous server answer), QueryCounterTimestamp (glQueryCounter, a one-shot stamp, not a begin/end pair) and WaitSync (the GPU-side wait FenceWait's client wait does not express). QueryTimestamp (MGPTimestampRequest, kCtxQuery, kReplySlot), QueryCounter (MGPQueryDesc with Kind = GL_TIMESTAMP, kCtxQuery) and FenceWaitServer (MGPFenceWait, kScreen) are APPENDED at the end of PipeCalls.def because the opcode is the position: SetSwapInterval stays 68, the three take 69-71, and PipeCatalogue.LateArrivalsAreAppendedWithoutRenumbering pins that. Header counts 71 (screen 11, query 8); the seven generators regenerated.
- P-3 MGPBufferRange inlined a 32-byte MGHostSpan into every range of every class - dead space on every SSBO, atomic-counter and XFB range, and D-B8 says not to freeze the named-UBO payload before the stage-ubo-named numbers exist. The range is 24 bytes now; the host spans are an optional second var-tail behind the ranges, announced by MGPShaderBuffers::HostSpanCount (0 or Count), with set_shader_buffers keeping its kVarTail|kHostSpan flags. PipeCatalogue.BufferRangeCarriesNoInlineHostSpan pins the sizes, the flags and the comparator's view of the count.
- P-4 QueryEnvUint64 parsed with base 0 (a leading zero meant octal: MOBILEGL_PIPE_PUSH=010 read as 8) and accepted -1 as every bit set; it is decimal or explicit 0x now and a '-' anywhere is refused with the warning (smoke through the integration binary: -1 and 12abc warn, 010 and 0x10 parse). The CI stdio gate's alternation now also catches fprintf(stdout, puts( and std::cout/cerr; it is green over MG_Backend and MG_State. MGPSubData states how the buffer half expresses [offset, size): UnionBox.X / UnionBox.W with Target == Buffer, Y = Z = 0, H = D = 1, one record bounded at a 2^31-1 offset and 2^32-1 size beyond which the emitter splits (the same rule the ring's half-capacity bound already imposes); MGPipeSetSubDataBufferRange / MGPipeSubDataBufferOffset / Size are the only spelling and PipeCatalogue.SubDataBufferRangeRidesInTheUnionBox pins the encoding and its bounds. gen_pipe.py now refuses, in both modes, a call payload named in PipeCalls.def with no field list in PipeFields.def (the four memcmp-fallback member types are the documented exception); shown by dropping P(MGPSwapInterval), which exits 1 naming the payload.
- The MGPPixelPackState size assertion compared sizeof against itself; it asserts the literal 28 PixelStoreParameters measures.
- Verified: ctest -L unit green in both the default and the split configuration, gen_pipe.py --check clean with the generated files committed, nm --defined-only of the default libMobileGL.so has no MG_Remote symbol, and the full integration-gpu suite passes (the *IsActuallyArmedWhenTheEnvironmentPinsItOn family trips under -j 8 as documented and passes serially).

# ------- Android API level policy: minimum 26, decided here and only here -------
# MobileGL ships against API 26: the codebase must not use any API introduced
# after 26. That usage constraint is enforced where it is real - the shipping
# gradle build compiles at minSdk 26, where a newer API is simply undeclared
# and fails to compile. Configuring at a HIGHER level is therefore allowed
# (nothing in the tree may rely on it), but a LOWER level would change the
# libc contract underneath the shipped library and is refused.
#
# This has to live at configure time because the level cannot be corrected
# from a source header. A `#define __ANDROID_API__ 26` in a common header
# only rewrites the macro for the bionic headers that happen to be included
# after it; any libc++ header pulled in earlier has already latched its
# feature macros at the real configure-time level. libc++ and bionic then
# disagree about which symbols exist - libc++ calls e.g.
# pthread_cond_clockwait while bionic, re-read at the lowered level, has
# hidden its declaration. MobileGL/Defines.h carried exactly that pin from
# the first commit until it was removed; this guard is what replaces it.
#
# Read the level back from the compiler target triple first. Its trailing
# number (aarch64-none-linux-android26) is precisely what clang turns into
# __ANDROID_API__, so it cannot disagree with the compile itself, and it is
# already past every NDK normalisation step - codename aliases, "latest",
# and per-ABI minimum pull-ups. ANDROID_PLATFORM_LEVEL is the fallback for
# generators/languages where the triple variable is not populated.
#
# Note CMAKE_SYSTEM_VERSION is deliberately NOT consulted: it holds the API
# level only under the NDK's newer toolchain path, and is a meaningless 1
# when ANDROID_USE_LEGACY_TOOLCHAIN_FILE is on (which is what AGP has been
# defaulting to). Reading it would fail every legacy-mode build.

# untrusted_app process, and writes a marker the parent reads back.
