- MGPipeBarriered(op, payload, applierState), IMPLEMENTED, not stubbed: the static wait-class
column plus the two payload-derived escalations the contract names (an open XFB span, a draw
carrying kDrawClientArrays). One function and two callers is the point - the emit table and
the sink must reach the same answer or the client runs on while the server reads a value that
has already moved. set_context_values now mirrors IsTransformFeedbackActive into the applier
state as well, because a predicate that read it out of gPipeInputs would be reading the very
block run-ahead stops filling.
- MGPipeApplierCurrentRecordIsBarriered() with the writer beside it. It answers true by default
and that IS the landed lockstep answer, not a stub: on a server without kCapRunAheadApply
every record is barriered and CONTRACT-P5C's two exemption scopes keep working unchanged.
- The sb applier fields (BoundShaderBuffers[3][84], the three windows, the writable masks and
ShaderBuffersSerial) and the pg record fields (the three binding tails, Signature,
BindingsSerial) with the two entry points MGPipeApplySetShaderBuffers /
MGPipeApplySetProgramBindings declared and ABORTING BY NAME.
- The by-handle backend seams in Managers.h with aborting bodies in one block: ResolveVaoTwin,
ResolveTextureTwin, ResolveProgramTwin, SyncTextureToBackendByHandle,
SyncMipmapsToBackendByHandle, and the FBO / RBO / program SyncToBackendByHandle overloads.
Five packages sit on opposite sides of these calls - tx2 writes what fb calls, fb writes what
tx2 needs, id rekeys the registries all three read - so the signature is fixed once here and
each family replaces a body. Abort and not null: a resolver that answered null renders a
blank draw and a sync that did nothing renders stale pixels, and both are green lanes.
- Coverage.def's GetBufferBindingPoint -> SetShaderBuffers row with BOTH of its PipeFill.cpp
switch arms and the pairing asserts, shape-only and inert. It lands with the contract package
because PipeFill.cpp belongs to the contract package for the whole phase - an emitter
enumerator whose dispatch arm lived in the family's worktree is the merge trap that file's
own comment was written about.
- FieldOwnership.def re-annotates the six object-class rows plus GetProgramForDispatch to
"P5e (Espryt unbarriered), P7 (Magma)", and the strict-abort case follows the string, which
IS the debt entry rather than decoration. kMGPipeMaxBufferBindingPoints is pinned against
BufferState.h's 84 where both are visible. gen_pipe_field_ownership's refusal count is 8.
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.
