- ROADMAP, MEASUREMENTS and ARCHITECTURE are rewritten as summaries (333 KB of index text -> 84 KB). ROADMAP's phase table is one line per phase plus a link; MEASUREMENTS keeps headline numbers under its old §1-§13 numbering (plus §14-§16 for P6.5, P7 and P12); ARCHITECTURE keeps every decided rule under the same §1-§17 / appendix numbering, so the `ARCHITECTURE.md §N` references in code still land, and §17 becomes an index of the phase landing shapes. - CURRENT_STAGE_PROGRESS now describes the current stage (the P12 on-screen-server subset) and absorbs CURRENT_STAGE_STATUS, which is removed. The P7 status tables, the P6 closing snapshot and the P6.5 first-wave snapshot move to notes/p7, notes/p6 and notes/p65. - Each phase gets notes/<phase>/README.md: a short summary, then the verbatim material that left the index documents (its ROADMAP row, its MEASUREMENTS section with subsection numbers kept, its ARCHITECTURE §17 part, milestones) and a file index. P8-P11 and P13 get their planned scope; the full open-question list moves to notes/OPEN-QUESTIONS.md. - The phase reports that sat at the top level move into their phase folders with unchanged names: P5D-INPROC-PERFORMANCE, P5E-RUNAHEAD, P5F-WIRE-COMPLETENESS, P6-SPAWN-PLAN, P6-CONTRACT-DRAFT, P6-ENDSTATE-REVIEW. Their relative links, CONTRACT-P6.md's links to them and one tool docstring are updated; notes/README.md maps every old path and section number to its new place. - 71 files under notes/recovered/ that were byte-identical copies of phase-folder files are removed. - Corrections made while condensing: the server process reads Transport as Spawn (CONTRACT-P6 §3.1 amended the old "child forces monolith" rule); both backends now publish kCapRunAheadApply; MOBILEGL_IPC_RESPAWN is a named refusal and MOBILEGL_IPC_IDLE_EXIT_S is not parsed; the Redmi pin row is in tools/device_bench/pin_device.sh. check_doc_citations over docs/Disaggregated/*.md: 0 problems. No relative link is newly broken.

摘要
- 异步 reply 语义，建立在 P6.5 的消息式 reply 之上；2 MiB reply cap 与 chunked readback（ID-47）；PACK-PBO 回读 fire-and-forget（ID-57）；武装剩余回调（
OnTextureWriteback、OnTexturePullRequest、OnMipLevelsGenerated、OnLog分级）；OnGlError有序；纹理拉取缓解 + 终止符；XFB 命名空间（DeleteTransformFeedback）。 - 门：回读 / XFB 场景在 split 下绿；
TextureRemintPullScenario；拉取计数逐 trace 发布；两条故障注入。
