CONTRACT-P7 §5.5. DirectVulkan had no StateObjectDeathOps at all, so under a Magma
inproc session NotifyStateObjectDestroyed reached nobody and the server was never told
that a frontend object had died. Package L measured the shape: with the WireTables
install condition made backend-agnostic, CtWireScenario's two death cases PASS on Magma
spawn and tcp - the remote client has no local backend, so the client-side emitter
installed there answers the notice - and FAIL on inproc, where the install condition
deliberately stands aside for "the backend's own dispatcher" and Magma had none.
g_magmaStateObjectDeathOps is that dispatcher. It mirrors g_glesStateObjectDeathOps
(DirectGLES/Managers.cpp:335) with ONE arm rather than two: Espryt's other arm destroys
a backend twin keyed by lifetime id, and Magma keeps no such twin - its two
client-minted kinds are keyed on {slot, gen} by MagmaPipeIdentityTables and the other
six are still reached from their frontend objects - so what is left is exactly the emit
of object_death off the apply thread. Installed from
BackendObject_DirectVulkan::Initialize(), i.e. ServerLoop::CreateBackend, step 1 of
InitServerRoleCommon: the one place BOTH Magma server roles pass through, and before any
client session exists. #if MOBILEGL_BUILD_DISAGGREGATED && MOBILEGL_PIPE_PUSH, so the
pull build compiles nothing new.
The two skip guards in CtWireScenario go with it. Every other "Magma installs none" site
the audit found is comment text whose ARGUMENT survives, and each is reworded rather than
deleted: the table emits the wire record and frees no client slot, so P4a's
backend-neutral NotifyAndFree is still the only thing that returns one, HandleRecycle's
C-1 case still measures the only protection the allocator has, and MagmaPipeArms' age
sweep is still the only thing that retires an identity slot.
The framebuffer death case now reads the client's allocator beside the server's tally.
That correction matters: the plan called this a slot leak provable with PipeSlotPeek, and
it is not - it has been backend-neutral since P4a. What leaked was the SERVER's twin, and
a framebuffer has no wire delete opcode at all, so object_death is its only delivery.
Two installers cannot race although the global is last-writer-wins with no stacking:
Magma's runs only in a process that owns a DirectVulkan backend, and
InstallClientWireTables' arm runs only under Transport == Spawn, which is by construction
the process that owns none.
RED-ONCE: `if (false) InstallStateObjectDeathOps();` reds the two Split cases alone
(`Expected: (afterCounters.deaths) > (deathsBefore), actual: 0 vs 0`, CtWireScenario.cpp:264)
and leaves spawn and tcp green - the exact split of responsibility the comment claims.

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
