swung0x48 2207b6d9ee [docs, MG_Backend, MG_IntegrationTest] (P7): package A's eight refusals are on record, and only real sites still carry @P7
notes/p7/magma-a.md: the per-site table (retired / declined / kept-fatal with the
reason), every red-once with its captured output, the gate readings, and what is
handed on.

The three places package A's own prose still named `uniform-buffer-byte-tail@P7`
lose the marker. They are comments, not refusal sites, and leaving the marker in
would have made a tree-wide `grep @P7` count them against packages B and C. The
census now reads 15 -> 7, and all seven are real: WireFramebuffer.inc x4 and
VulkanRenderer.cpp x1 (package B), WireDraw.inc x2 (package C).

Three findings worth the integrator's attention, all in the note:

1. Most of this cluster was unreachable, and that is provable rather than
   assumed. The frontend validates buffer-range offsets against the very caps the
   backend then re-checks - GL_{UNIFORM,SHADER_STORAGE,TEXTURE}_BUFFER_OFFSET_ALIGNMENT
   and GL_MAX_UNIFORM_BLOCK_SIZE are all published from the same Vulkan limits -
   so five of the eight sites could only ever have fired on a malformed peer. The
   two that CAN fire are `uniform-buffer-byte-tail` (GL constrains a range's
   offset but not its size) and `unaligned-atomic-buffer-range` (GL gives
   GL_ATOMIC_COUNTER_BUFFER no queryable alignment, so the frontend only enforces
   offset % 4 while the backend needs minStorageBufferOffsetAlignment).

2. fatal_census does not move for any of this, and no re-baseline is due. Wave 0
   already routed these funnels through MGPipeSessionFailHook, so the abort lives
   in FatalFunnel.cpp and retiring a WireDescriptorFatal call site changes no
   census number: 79 abort sites / 43 family words, unchanged, RC=0. The brief
   expected the count to fall because the sites were bare aborts before wave 0.

3. DirectVulkan.Split.Full.IterationRPProgram203Scenario.FixedCompleteInputProducesFixedCompleteGoldenOutput
   is red on this worktree's build-split and is NOT ours: it reproduces 3/3 with
   package A's backend diff fully reverted, and the mismatch bits are identical
   to the S1 exposure texel in magma-two-process-first-run.md. The contract books
   that one against the tcp arm, and ~/w7/pipe's own build-split passes it, so
   whether it is a split-arm regression between 460a3a72 and 610fa281 or a
   configure-dependent S1 needs the integrator.

Gates on the finished branch: integration-magma-split 75/75, -spawn 54/54, -tcp
56/56, -buffers 21/21, full-split 512 entries 454 PASS / 57 SKIP / 1 red (the
pre-existing one above; base was 453/57), ctest -L unit 2408/2408,
spawn_lane_parity RC=0, link_ratchet unchanged at 186, fatal_census RC=0, and G1
pull .text = a52203 with nm --defined-only identical to p7-before/pull-syms.txt
(added=0 removed=0).

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

  1. 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。
  2. 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
