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).
工作笔记（原 ~/w7/notes/）
这一层是 MGPipe 各阶段的工作笔记原件：包计划（BRIEF-*.md）、契约草稿、集成者逐条裁定
（INTEGRATOR-DECISIONS-*.md）、只读审计、普查、设备记录、包任务书（TASK-*.md）与阶段报告。
它们此前只存在于一台机器的 ~/w7/notes/ 下。上层那几份文档（ROADMAP.md、
CURRENT_STAGE_PROGRESS.md、MEASUREMENTS.md …）大量引用它们——裁定编号、审计行号、
逐门数字的出处几乎全在这里。一份引用了几百次、却只存在于本地未跟踪目录的记录，等于没有记录。
所以整体移进仓库。
路径映射
~/w7/notes/<phase>/<file>.md → docs/Disaggregated/notes/<phase>/<file>.md
上层文档里凡写作 ~/w7/notes/... 的 .md 引用，都按这条规则读。
移进来的是什么，没移的是什么
| 移进来了 | 全部 .md，415 份，约 11 MB，目录结构原样保留 |
| 没有移 | 脚本（.sh / .py）、运行日志（.log / .out / .err）、普查与门的结果数据（.json / .txt / .tsv）、补丁、APK 与 .idsig、nm 转储 |
没移的那些仍在 ~/w7/notes/ 与各构建树下。它们是证据数据而不是文档：体积大、随每次运行
重新产生、且多数只在产生它的那台机器上有意义（绝对路径、设备序列号、构建目录）。上层文档引用
它们时给的是路径，不是内容。
两个需要知道的例外
- P6 的包计划已提升为正式文档：原
~/w7/notes/p6/BRIEF-P6.md现在是../P6-SPAWN-PLAN.md，本目录不再保留副本，避免两份同源文档各自漂移。 契约草稿同理，见../P6-CONTRACT-DRAFT.md。 recovered/是从失败的 workflow 运行里捞回来的材料（wf1…wf5），与同名阶段目录 可能重复，保留是因为其中几份是当时唯一的完整版本。查阶段记录请先看阶段目录。
不受 citation lint 管
CI 的文档引用 lint 只吃 docs/Disaggregated/*.md（非递归，.github/workflows/test.yml），
本目录不在其中，这是有意的：这些笔记的 file:line 是写在各自当时的代码头上的，拿今天的
HEAD 去解析必然大面积失败，而那不是错误——那是它们作为历史记录的正确状态。要核对某份笔记的
引用，用它自己声明的那个 revision：
python3 scripts/check_doc_citations.py --rev <当时的头> docs/Disaggregated/notes/<phase>/<file>.md
