set_context_values (opcode 79, MGPContextValues 96B, kCtxState) carries the active texture
unit, the max touched unit, the fifteen touched-binding-point counts and the five value-class
XFB rows, emitted at validate under the subsystem bit and hash-suppressed as a whole; the
emit gate and the residual-skip gate read the same answer so they can never disagree.
MGPipeApplySetContextValues writes gPipeInputs (the PackState shape). MGPAttribValue grows
24->56B to carry the frontend's converted three views, and MGPipeApplySetVertexAttribDefaults
finally writes them (the 'ignores MGPAttribValue::ValueClass' warning dies), so
GetCurrentVertexAttribute leaves the refusal set. The three texture shutters answer the
applier's own serials under a server-stamped verb (APPLIER_DERIVED), storage answer kept
verbatim elsewhere. FieldOwnership.def: nine value-class rows become derived RECORD_SUPPLIED,
the three shutters APPLIER_DERIVED, the nine object-class rows keep their phases;
FieldOwnershipTest pins that the remaining pulls are exactly the object-class list.
gen_pipe.py gains SCAN_EXEMPT_ACCESSORS with per-name reasons and retiring phases (it repairs
the --check gate the hd merge's two G6 probes had left red).
Evidence: unit 2175/2175; integration-split 111/111; both generators' --check and
--self-test green; rsp on the Xfb capture scenario 36 -> 22; red-once - gating the emission
off turns seven named scenarios red, restoring returns 111/111. CONTRACT-P5C section 5.3.
