[MG_IntegrationTest, docs] (P7): the upload-shape gate was measuring its own bounding box; inset the scatter so the box/rect decision is reachable
Rework round 2 of 4 after the D2 review (fable, ID-P7-8), which found that this gate's
numbers were right and its SUBJECT was wrong.
The scatter wrote 40 2x2 rects at x=((i*7)%32)*2, y=((i*5)%32)*2 into a 64-px atlas.
Both strides are surjective onto 0..31 over 40 iterations - rect 9 lands at x=62, rect 19
at y=62 - so the rects' union box covered the WHOLE LEVEL, and the server's subRectEligible
(Managers.cpp:8486-8491) requires !dirtyRegion.CoversWholeLevel, a BOUNDING-BOX test
(MipmapStorage.h:30-33). Both scatter textures were rect-INELIGIBLE on every arm before
:8649's unpack-ring policy was ever consulted. The box-versus-rect decision the scenario
exists to pin was never reached for the two textures it scatters into, and the only
texture that could move under any red-once was the contiguous control band - which is
exactly what the old substitute red-once's box=6 rect=3 jobs=12 was.
kScatterMargin insets the scatter by one rect: same 40 writes, same coarse stride, union
box bounded at (2,2)..(62,54). The gold row is UNCHANGED at emit=9 box=9 rect=0 jobs=9 on
all four arms - but it now means what it says.
THE RED-ONCE IS NOW ZERO-PATCH, which is stronger than the throwaway source edit it
replaces: MOBILEGL_ESPRYT_DISABLE_UNPACK_RING=1 alone gives box=3 rect=6 jobs=183 with
bytes/f[tex] falling from 104448 to 9024, while all 26 pixel cases stay green. BOTH
SCATTER TEXTURES moved - box=3 is the contiguous band alone, rect=6 is the plain atlas
AND the atlas written through the glTextureView, and jobs=183 = 3 + 6x30 confirms thirty
rects per scatter emission. The same knob was green before the inset, which is the
evidence that CoversWholeLevel was short-circuiting the decision.
The three prose sites are rewritten accordingly: the scenario's gold-table rationale, the
MEASUREMENTS.md 13.1 reading and the package note's red-once section now explain
attempts 1-3 as mutations of a decision the client already makes correctly, and attempt 4
by CoversWholeLevel rather than by the ring.
Also PipeStatsWindow gains LastFrom{Client,Server}LogSince, and the gate reads its two
role windows since a mark taken before the counted workload. The server writes an EMPTY
teardown window after the counted one, so "the last line in the file" is one shutdown
away from reporting four zeroes as the workload's shape. Moving to a marked read exposed
a second latent defect in the same assertion: ASSERT_TRUE(clientWindow.found) over the
whole file was satisfied by the "counters ON" BANNER in all three split arms, claiming a
window had been read when none had. The assertion is now on the window that actually
carries the tex[] bracket.

[MG_Pipe, MG_Impl, MG_Test, docs] (P7): D-K2's dependency rule in one table, with the case that fails when the two readers disagree
P3b/P4b R-5 (and R-3's cheap half), landing under the P7 program (PLAN-PH-P34B-P7.md
1.2, wave 2-D package D2).
The rule had SIX statements and nothing compared them, and two of the four prose ones
were wrong in the same way: MG_Pipe/MGPipe.h and MG_Backend/DirectGLES/Managers.h both
said "THREE OF THEM HAVE A DEPENDENCY" (there are six rows) and both said "the mirror
pairs (10 without 11, ...) are all fine" - when 10-without-11 is precisely D-K2's FOURTH
row (ID-14/ID-15), refused by the server and withheld by the client, with PipeFill.cpp
saying so out loud: "The brief's original 'bit 10 without 11 is fine' is WITHDRAWN for
P4a as built." Neither wrong comment could fail anything; Managers.h's copy sits in the
header of the file that implements the refusal.
The rows, once, in MG_Pipe/SubsystemDeps.def (X-macro, FatalFamilies.def's convention),
expanded by MGPipe.h into kMGPipeSubsystemDependencies[] / MGPipeSubsystemRequires() /
MGPipeSubsystemDependenciesAreSet() with four static_asserts. Six rows: 8->7, 9->10,
10->{7,11}, 11->10, 12->none (a ROW, not an absence), 13->7. Bits 8 and 13 are the two
the old comment did not know about; bit 13's row lived fifteen lines further down in the
same header, which is how "THREE OF THEM" survived two phases.
THE TWO READERS DO NOT YET READ IT, deliberately: MG_Impl/Pipe/PipeFill.cpp is the
contract package's file for the whole phase (TextureEmit.h states that rule) and
MG_Backend/DirectGLES/Managers.cpp belongs to wave 2-D package D1 while it is in flight.
Switching them is two one-line changes for the integrator. The anti-drift property does
not wait: MG_Test/Backend/DirectGLES/SubsystemDepsTest.cpp is the first thing in the tree
that calls BOTH readers at the same mask - sweeping the phase constants, the two
documented refusal lanes and one mask per row - and compares each against the .def. It
lives in that binary because that binary links both sides.
Both comparisons are one-directional, each for a measured reason. The server resolvers
also fold in the family's own bit and D-C3's wire-caps refusal, so a resolver may say NO
for its own reasons but never YES where the table refuses. MGPipeP4aFamilyEmits is a
QUADRUPLE and the first version of this case asserted equality and reddened at 0x1fff on
the sampler and program families because a bare unit binary registers no consumer - the
assertion being wrong, not the product, and recorded in the note because the temptation
to assert equality here is strong.
Red-once (R-16), twice: dropping the fourth row from the .def fails at COMPILE time
(MGPipe.h's static_asserts); making the server's ResolveSamplerSubsystemArm stop checking
bit 10 (throwaway, reverted) reds the runtime case and names the mask - 0x9ff, which is
exactly the lane CMakeLists.txt already pins for G12.
R-3's cheap half: CONTRACT-P5.md claimed the image-access, sampler-view-target and
draw-buffer encodings as contract by pointing at package-header LINE RANGES, and all
three had drifted (ImageEmit.h:146-159 no longer holds the encoding at all). All three
rows now state the encoding by enumerator and function name, and the two confusable
siblings are named. The remaining half - MGPSamplerView::Target still has no Count bound,
no ...IsValid and no Fatal for an out-of-range value - is stated in the row rather than
closed, being an MG_Pipe change outside this package's footprint.
Managers.h:690-695's copy of the wrong prose is NOT corrected here: it is package D1's
file, and its two defects are named in notes/p34b/espryt-d2.md so the integrator can take
them in one line.
G1 after this change: pull .text 10822147 = 0xa52203, nm --defined-only identical to
~/w7/p7-before/pull-syms.txt (30570 symbols) - the new inline constexpr table does not
reach the pull build.

[MG_IntegrationTest, docs] (P7): the texture upload shape becomes a gate, with the view remap inside the workload
P3b/P4b R-11 / D-D4, landing under the P7 program (PLAN-PH-P34B-P7.md 1.2, wave 2-D
package D2). P4a recorded the emission shape rather than gating it because the
per-storage-owner cursor with view/owner remapping was the next phase's and gating an
unfinished shape pins a non-answer. That work landed, so the RecordProperty block is
now EXPECT_EQ against a gold row MEASURED on this cursor, and the workload carries a
third texture written through a glTextureView so the remap is inside the counted
window.
The gold row, identical on monolith / inproc / spawn / tcp:
emit=9 box=9 rect=0 jobs=9, client emitter 9
keyed on the workload constants by static_assert. P4a's emit=6 box=6 rect=0 jobs=6
was a two-texture workload with no client emitter and is not comparable.
The client half is read from MGPipeTextureEmitter::SubDataCount() rather than from
ctu=, and that is a correction: under spawn and tcp the two roles are two processes
whose PipeStats windows close on different Present cadences (measured ctu=13 against
emit=9, and usually not yet written when the case reads), so ctu == emit is not a
well-posed comparison there. The log field is kept as a record and asserted only
where the transport says the two are window-aligned - asking the NUMBER was the first
mistake, because the server publishes a readable ctu=0 under spawn and the comparison
silently became 0 == 9. PipeStatsWindow gains LastFromClientLog/LastFromServerLog.
Split/spawn/tcp arms added as explicit per-arm blocks rather than through
mgl_itest_register_split_arms: the macro hands every arm the shared environment, and
this case needs a lane marker, PipeStats period 1, a push mask and above all a
MOBILEGL_LOG_FILE_PATH private to the arm - the library opens the log "w", so two
entries sharing a path truncate each other and the failure looks exactly like "the
counter was never emitted".
Red-once (R-16): the prescribed flip of summedArea*4 >= unionArea*3 leaves the gate
GREEN, and that is a finding. Two gates downstream dominate it - the server needs
dirtyRectCount >= 2, and UnpackRingAvailable() zeroes the rect list by design ("one
box, one job", the existing Mali-cliff mitigation). So rect=0 is the policy's
intended output, not an accident of the scatter pattern. The red-once that bites
splits the union box in two AND disables the unpack ring: box=6 rect=3 jobs=12
against the gold, while 26 pixel cases stay green. Four attempts and their reasons
are in the note.
The Mali frame-time delta D-D4 asks for beside the gold is NOT schedulable - one
Redmi, an Adreno, no Mali part - and is recorded as a declared deviation in the
scenario header and MEASUREMENTS.md 13.3 rather than modelled.
Also corrects the three places that said the client emitter had not landed: the
scenario header, the CMake probe's comment, and gates-v1.md's re-run table.
TextureEmit.h's EmitOneLevel has been incrementing it.

[MG_IntegrationTest, docs] (P7): the owner-keyed emission cursor gets the scenario that can see it
P3b/P4b deepening, landing under the P7 program (PLAN-PH-P34B-P7.md 1.2, wave 2-D
package D2). The code half of "按存储属主键控的发射游标与 view 索引重映射" landed in
P4a/P5e; this is the verification half it never had.
TextureViewAliasScenario, four cases: an upload through a layer-restricted view
sampled through the owner and the reverse, each once and again across draw
boundaries so the drain runs three times. Each case asserts on TWO channels at
once - sampled texels AND MGPipeTextureEmitter's SubDataCount / RefusedSubDataCount
/ DrainListSize, read through the new Harness/TextureEmitPeek. The counters are the
load-bearing half: a level that never made it onto the drain list is still uploaded
by the next whole-level respecify, by a glGenerateMipmap or by the monolith sync
path, so the picture comes out right one frame late and a pixel-only case goes green
over the regression on most trees.
Registered in the three GLES split arms, and MOBILEGL_ESPRYT_ENABLE_TEXTURE_VIEW=1
added to MGL_ITEST_GLES_{SPLIT,SPAWN,TCP,TCPDEVICE}_ENVIRONMENT - views are Espryt's
opt-in and without it every case green-skips. The Tcp arm needed the knob on the
TcpServer.Start fixture as well: that lane's server is pre-started rather than
spawned from the client, so it withheld GL_ARB_texture_view and all four cases
SKIPPED while the identical Split and Spawn arms ran.
Red-once (R-16): TextureObjectView::MarkStorageDirtyRegion made to call
PipeNoteLevelDirty on ITSELF instead of forwarding to the storage owner - the
two-cursor shape. TheViewUploadDrainRunsAgainAfterADrawBoundary goes red on both
channels simultaneously (stale owner texels AND SubDataDelta() == 0). The plan
predicted case (a); it is (c) that reds, because the first drain of a texture's life
carries the whole level anyway - recorded in the note.
TheOwnerUploadDrainRunsAgainAfterADrawBoundary is EXCLUDED BY NAME from the split
arms: it is red on all three transports and green under monolith, because an
owner-side resource_subdata moves only the owner's record.Serial and nothing
propagates that to the records viewing it. Cause and the two candidate fix sites are
named in the CMake comment and in notes/p34b/espryt-d2.md. The name stays in every
lane (G14).
