- MGPipeShaderCsoRecord gains Archive, a SharedPtr<const ProgramArchive> the create
ADOPTS under a transport. Before this the applier stored the descriptor and the two
companion pointers named the frontend's own LinkArtifacts/SpirvArtifacts, which
ProgramObject::Link() replaces in place - so every reflection read on the apply thread
was torn or stale by construction the moment the client runs ahead (gap G-A).
- MGPipeApplyCreateShaderState takes the archive as a fourth argument, undefaulted for
PipeRoute.h's stated reason: a caller that has one and forgets it would compile, and
the failure would be silent. Null on the monolith arm, which keeps its frontend arms
token for token (ruling 1 / ID-81).
- ProgramArtifactsCodec gains ProgramArchive and the FRAME. SpirvArtifacts carries no
stage list and MGPProgramDesc::StageMask cannot stand in for one: it is a bit set, and
GL lets two shader objects share a stage, so a list rebuilt from it can be shorter than
generatedSpirv - which the backend pairs with it by one running index.
- Codec completeness, as CONTRACT-P5E §5.5 asks: the skipped member is named
(LinkArtifacts::program, the live glslang TProgram) and proven unread by either backend
twin; the libc++ caveat at the size echo is read as what it is - a cross-toolchain
check, exact for an in-process split - and both verdicts are written where they were
asked for.
- set_program_bindings (opcode 80) lands end to end: EmitProgramBindings on the client,
the FIFTH ROUTE ESCAPE (three tails in three index spaces plus a parallel name array -
no generated row can express it, so op 80's gMGPipeContext slot stays null as
PipeCatalogueTest pins), the wire emitter, the decoder arm that resolves and
NUL-checks every name span, and the applier body that copies the names into the record
(rule C) and advances BindingsSerial.
- The record is emitted AFTER create_shader_state, not before as the draft note said: a
re-issued create clears all three tails because they index into the archive it just
replaced, so bindings published ahead of it are wiped by the create that follows.
- MGPProgramDesc::LinkStatus is filled, and ID-88 is VERIFIED rather than assumed:
ProgramObject::Link()'s prologue bumps m_linkVersion and assigns m_artifacts = {} -
"the complete not-linked state" - before the body runs, and every ProgramLinkTask
failure arm leaves linkStatus false. A failed relink therefore reports unlinked, the
re-issue carries LinkStatus = 0, and nothing needs an object_death.
- ID-87's measurement gets its instrument: the archive's byte count is added to
PipeStats' CsoBlobBytes where the bytes actually exist, one sample per link.
