#
# THE LANE CASE THAT PROVES THE RECORDS CROSSED, and it is a RESULT and not a probe (R-16:
# a probe may not arm against a stub). Each of these four scenarios asserts a value that
# only exists if the verb ran on the apply thread - the texel a compute shader stored
# through an image unit, the word glCopyImageSubData moved, the counter an atomic add left
# behind, the block a program pipeline rebound - so a sink that DECLINED, or a client that
# fell through to the driver, is red by the number it reads back and not by a tally.
#
# Before i1 every one of these aborted at the client's Fatal{UnmigratedVerb} on the first
# glBindImageTexture / glDispatchCompute / glCopyImageSubData / glShaderStorageBlockBinding;
# all four are green under inproc now (the census: 13 + 6 + 11 + 3 DirectGLES entries).
# RED ONCE BY DOING X: return false from ServerVerbSink::OnLaunchGrid before the
# gl.DispatchCompute call and UnboundImageDescriptor / AtomicCounter / ProgramPipeline all
# read back their initial values.
#
# THE FILTERS ARE NARROWED TO THE CASES THAT ACTUALLY EMIT, and that is ScenarioFixture's
# rule rather than a convenience: an armed `DirectGLES.Split.` case must move the client
# encoder's record ordinal (ScenarioFixture.h:86), because a lane whose workload produced no
# record is the "resolved the transport and then fell through to the driver" shape that
# every pixel assertion is blind to. ProgramPipelineScenario's other nine cases are pure
# name/state cases that draw nothing, so the whole-scenario filter would arm them and they
# would be red for having nothing to say. The two named here are the ones that were

# ---- P5b t2: the transform-feedback spans, the XFB object bind, the patch parameter -------
#
# MG_Remote/CONTRACT-P5B.md §2 t2. The three P5 lanes above are the REDUCED PATH's targets
# (a clear, a triangle, a persistent map); these two are the first lane entries whose GREEN
# DEPENDS ON A t2 RECORD HAVING CROSSED AND BEEN APPLIED BY THE BACKEND, which is the only
# statement a package flipping a verb can make that a unit case cannot:
#
# TessellationXfbCaptureScenario covers BOTH halves of t2 in one workload. Every case
# calls glPatchParameteri(GL_PATCH_VERTICES, n) and then draws GL_PATCHES into a
# transform-feedback capture, and asserts the CAPTURED BYTES. A patch_parameter (73)
# that did not reach the server tessellates at the previous patch size and the capture
# is the wrong length; a begin/end_stream_output (62/63) that did not reach it leaves
# the buffer holding the scenario's poison value, which is what those cases print.
# XfbCaptureBufferReuseScenario is the span family alone, across four buffer lifetimes
# (a buffer per span, one immutable-storage buffer, one respecified buffer, a
# respecification that changes the capture size). It is the case that would notice a
# span whose END crossed but whose BEGIN did not, because the second span's bytes
# would be the first span's.
#
# Both are DirectGLES only, deliberately, and the reason is measured rather than assumed:
# under Magma the capture is written into the server's resident slice and there is no route
# back, because MG_Backend/Init.cpp's ConsumedSubsystemsFor(DirectVulkan) withholds
# kMGPipeSubsystemResources, so BufferObject::SyncGpuWrites() emits no resource_readback.
# Every DirectVulkan XFB capture entry in the inproc census fails on exactly that (t2-v1.md
# §"the 51"), and it retires with P7 (Magma's resource family) / P9 (the readback carrier) -
# not here. A DirectVulkan arm of this lane would be red for a reason t2 cannot fix.

//
// RULE D, WHICH IS WHY THESE ARE SHORT. A P5b verb crosses AS THE CALL: the record
// carries the GL arguments verbatim - the enums as tokens, the GL names the backend

// ServerVerbSink reproduces the backend call the monolith makes. The backend keeps
// reading the frontend state it reads today through the BARRIER-PULLED fields of its
// verb class, which the record's own verb stamp is what makes legal. So a migration is
// one emitter here plus one sink body there, and nothing in the backend moves.
//
// THE HANDLES ARE LOOKED UP, NEVER MINTED, and that is a ruling (i1-v1 §4). The sinks
// below dispatch on the GL NAME - that is the whole point of carrying it - so a handle
// is carried for P7's sake only. FindByLifetimeId answers the handle the resource
// subsystem has already published for this object and kMGPipeNullHandle when it has
// published none; Acquire would MINT one here instead, at a call site that emits no
// create record, and the server would then be handed an identity it has never seen.
