- Three P0 gates from plan B section 11, in one job that needs no build: a broken build
must not be able to hide a drifted interface.
- pipe-gen-check regenerates G1-G7 and runs git diff --exit-code over
MobileGL/MG_Pipe/generated. Since all seven generators read the same .def files, this is
what makes drift between them impossible rather than merely unlikely.
- The stdio gate refuses fprintf(stderr and printf( under MG_Backend and MG_State. Nothing
there matches today, so it lands with NO whitelist - verified with a negative control
that fprintf(stderr and std::printf both trip it while snprintf does not. Per-draw
instrumentation has been committed by accident before, once inside a mutex critical
section, and MGLOG_D is the channel these trees are allowed to use because it compiles
out in INFO builds.
- scripts/gen_pipe_dirty_surface.py reports the frontend mutation surface corollary 4
needs covered: 926 mutator calls under MG_Impl/GLImpl over 73 distinct mutators, of
which only 92 sit in a function that also reaches the backend. The other 834 are
published by the NEXT verb, which is precisely the population that needs an aggregate
generation. Informational in P0; it becomes a gate in P1 when there is a mapping file to
diff against.
- scripts/check_doc_citations.py resolves every `path:line` citation against a git
revision. It reproduces the failure that motivated it - the plan's first draft cited
SamplerObject.h:468-492 in a 160-line file - and reports 84 unresolved citations out of
1028 in docs/Disaggregated today, which is why CI runs it warning-only until those
documents settle. --strict exits 1, verified in both directions.
