 ## Problem
 
-Standing docs accumulated repeated rules, retold incidents, duplicated package maps, and stale Agent Note summaries despite existing writing guidance. Because review alone did not prevent that growth, the repository needed a mechanical budget alongside its documentation taxonomy.
+Standing docs accumulated repeated rules, retold incidents, duplicated package maps, and stale Agent Note summaries despite existing writing guidance. That guidance also did not define how a document's place in the hierarchy limits its scope or how ordered teaching differs from lookup-oriented material. Because review alone did not prevent that growth, the repository needed a mechanical budget alongside its documentation taxonomy.
 
 ## Decision
 
-- **A tier taxonomy with one home per fact.** [docs/AGENTS.md](../../../../docs/AGENTS.md) is the documentation standard: it assigns every Markdown tier a single job (standing orders, system map, type catalog, decision records, incident stories, how-tos, per-package contracts, generated catalogs, workflows), forbids restating a fact outside its home tier (link instead), and carries the slop checklist used when writing or reviewing any doc.
+- **Structure follows the documentation tree.** [docs/AGENTS.md](../../../../docs/AGENTS.md) is the documentation standard: a document owns detail about its subject, summarizes only the purpose, responsibility, and high-level behavior of direct children, and links to deeper owners. [Agent Notes](../../README.md) remain outside this structural contract. Every human-facing document is a tutorial with an ordered outcome or a reference with an explicit lookup scope; a [postmortem](../../../../docs/postmortem/README.md) is an incident-scoped reference whose chronology records evidence. Tutorials introduce concepts in prerequisite order for the reader's starting knowledge.
+- **A tier taxonomy with one home per fact.** The standard assigns every Markdown tier one job, forbids restating a fact outside its home tier, and carries the slop checklist used when writing or reviewing any doc.
 - **A narrow, hard budget gate.** [scripts/verify-doc-budgets.ts](../../../../scripts/verify-doc-budgets.ts) joins `doc-sync`: every doc listed in [scripts/doc-budgets.manifest.json](../../../../scripts/doc-budgets.manifest.json) must stay under its word ceiling (`wc -w` semantics, whole file), and a budgeted file that is missing fails the gate so a rename cannot silently orphan its budget. Scope is deliberately only the accretion-prone standing docs — the root and subtree `AGENTS.md` files, `architecture.md`, `packages/README.md`, and the standing policy docs they evict content into (`docs/testing.md`, `docs/defensive-patterns.md`). Reference docs, Agent Notes, and package READMEs are unbudgeted: length is legitimate there when every row is a fact, and review plus the slop checklist govern them.
-- **Ceilings are an enforcement frontier that ratchets.** A ceiling sits at least 5% above the doc's current size — working headroom, so routine wording edits pass while real growth still trips the gate — and ratchets down, keeping that margin, as the doc is brought to its target budget (root `AGENTS.md` ≤ 1,500 words; `architecture.md` ≤ 1,800; subtree `AGENTS.md` ≤ 600; `packages/README.md` ≤ 600). When the gate goes red the fix is to relocate or condense per the taxonomy; raising a ceiling is permitted only with explicit justification in the PR description, the manifest diff being the reviewable act.
+- **Ceilings are an enforcement frontier that ratchets.** A doc at or below its target keeps at least 5% headroom as its ceiling ratchets down; a doc above target keeps a frozen ceiling that prevents growth until it reaches the target (root `AGENTS.md` ≤ 1,600 words; `architecture.md` ≤ 1,800; subtree `AGENTS.md` ≤ 600 except `packages/AGENTS.md` ≤ 650 and `docs/AGENTS.md` ≤ 1,250; `packages/README.md` ≤ 600). When the gate goes red, relocate or condense; raise a ceiling only with explicit PR justification.
 - **A thin workflow skill, contracts in docs.** [.agents/skills/dsh-doc-standards](../../../skills/dsh-doc-standards/SKILL.md) carries the placement/audit/red-gate workflow and defers to the standard as its source of truth, the same split as [dsh-translate-docs](../../../skills/dsh-translate-docs/SKILL.md) over the i18n contract.

 ## Consequences
 
-- Adding to a budgeted doc now requires displacement: relocate the addition to its taxonomy home with a pointer, or condense existing prose to pay for it. Growth without pruning fails CI.
-- The bring-under-target rewrites land as stacked follow-ups that ratchet the manifest down as they merge; until each lands, its doc's frozen ceiling only prevents further growth.
+- Adding to a budgeted doc requires displacement: relocate the addition to its taxonomy home with a pointer, or condense existing prose to pay for it. Growth without pruning fails CI.
+- Structural review starts with ownership and document form before sentence-level editing, so lower-level detail moves to its owner instead of being polished in the wrong place.
+- Budgeted docs that remain above target cannot grow; reaching the target restores the 5% working headroom.
 - Word count is a crude proxy accepted deliberately: it cannot judge quality, but it forces the relocation decision at exactly the moment content is being added, which is when the author has the context to place it correctly.

 ## 问题
 
-尽管已有写作指导，常设文档仍不断累积重复规则、反复讲述的事故、重复的包映射，以及陈旧的 Agent Note 摘要。仅靠评审无法阻止这种增长，因此仓库需要在文档分类体系之外再配一套可自动执行的预算。
+尽管已有写作指导，常设文档仍不断累积重复规则、反复讲述的事件、重复的包（package）映射，以及陈旧的 Agent Note（agent 决策记录）摘要。该指导也未明确文档在层级中的位置如何限定其内容范围，以及按顺序引导读者学习的内容与面向查阅的材料有何不同。仅靠评审无法阻止这种增长，因此仓库需要在文档分类之外再配一套机械预算。
 
 ## 决策
 
-- **每项事实只归属一处的层级分类体系。**[docs/AGENTS.md](../../../../docs/AGENTS.md) 是文档标准：它为每种 Markdown 层级分配单一职责（常设指令、系统图、类型目录、决策记录、事故叙事、操作指南、各包契约、生成的目录、工作流），禁止在事实归属层级之外重复陈述（应改为链接），并包含编写或评审任何文档时使用的赘余检查清单。
-- **范围窄且严格的预算门禁。**[scripts/verify-doc-budgets.ts](../../../../scripts/verify-doc-budgets.ts) 接入 `doc-sync`：[scripts/doc-budgets.manifest.json](../../../../scripts/doc-budgets.manifest.json) 列出的每份文档都不得超过其词数上限（采用 `wc -w` 语义，统计整个文件）；预算内文件缺失也会使门禁失败，使文件重命名无法悄然摆脱预算约束。范围刻意只涵盖容易膨胀的常设文档——根目录和子树中的 `AGENTS.md` 文件、`architecture.md`、`packages/README.md`，以及它们将内容移入的常设策略文档（`docs/testing.md`、`docs/defensive-patterns.md`）。参考文档、Agent Note 和包 README 不设预算：只要每一行都是事实，长度在这些位置就是合理的；评审和赘余检查清单负责约束它们。
-- **上限是会逐步收紧的执行红线。** 上限设定为文档当前词数的至少 105%（留出工作余量，使日常措辞调整能通过，而真正的膨胀仍会触发门禁），并随着文档被精简到目标预算而同步下调、保持该余量（根 `AGENTS.md` ≤ 1,500 词；`architecture.md` ≤ 1,800；子树 `AGENTS.md` ≤ 600；`packages/README.md` ≤ 600）。门禁变红时，修复方式是按分类体系迁移或压缩内容；只有在 PR（Pull Request）描述中给出明确理由时才允许提高上限，manifest（元数据清单）的 diff 本身就是可供评审的变更。
-- **精简的工作流 skill（技能），契约归文档。**[.agents/skills/dsh-doc-standards](../../../skills/dsh-doc-standards/SKILL.md) 承载文档放置、审计和门禁失败处理工作流，并以文档标准为真源，与 [dsh-translate-docs](../../../skills/dsh-translate-docs/SKILL.md) 和 i18n 契约之间的分工相同。
+- **结构遵循文档树。**[docs/AGENTS.md](../../../../docs/AGENTS.md) 是文档标准：文档负责承载其主题的详细内容，仅概述直接子项的目的、职责和高层行为，并链接到更深层内容的归属文档。[Agent Note](../../README.md) 仍不受这一结构契约约束。每份面向人的文档要么是按顺序引导读者达成结果的教程（tutorial），要么是查阅范围明确的参考文档（reference）；[事故复盘（postmortem）](../../../../docs/postmortem/README.md) 是范围限定于单个事件的参考文档，其时间线记录证据。教程结合读者的起始知识，按前置依赖顺序介绍概念。
+- **每项事实只归属一处的层级分类。**文档标准为每种 Markdown 层级分配单一职责，禁止在事实归属层级之外重复陈述，并包含编写或评审任何文档时使用的赘余检查清单。
+- **范围窄且严格的预算门禁。**[scripts/verify-doc-budgets.ts](../../../../scripts/verify-doc-budgets.ts) 接入 `doc-sync`：[scripts/doc-budgets.manifest.json](../../../../scripts/doc-budgets.manifest.json) 列出的每份文档都必须低于其字数上限（采用 `wc -w` 语义，统计整个文件）；预算内文件缺失也会使门禁失败，使重命名无法悄然遗落其预算。范围刻意只涵盖容易膨胀的常设文档——根目录和子树中的 `AGENTS.md` 文件、`architecture.md`、`packages/README.md`，以及它们将内容移入的常设策略文档（`docs/testing.md`、`docs/defensive-patterns.md`）。参考文档、Agent Note 和包 README 不设预算：只要每一行都是事实，长度在这些位置就是合理的；评审和赘余检查清单负责约束它们。
+- **上限是只进不退的执行红线。** 达到或低于目标的文档在上限逐步下调时保留至少 5% 的余量；高于目标的文档则维持冻结的上限，在达到目标之前不得增长（根 `AGENTS.md` ≤ 1,600 词；`architecture.md` ≤ 1,800；子树 `AGENTS.md` ≤ 600，但 `packages/AGENTS.md` ≤ 650、`docs/AGENTS.md` ≤ 1,250；`packages/README.md` ≤ 600）。门禁变红时，迁移或压缩内容；只有在 PR（Pull Request）描述中给出明确理由时才提高上限。
+- **精简的工作流 skill（技能），契约归文档。**[.agents/skills/dsh-doc-standards](../../../skills/dsh-doc-standards/SKILL.md) 承载放置/审计/红灯门禁工作流，并以文档标准为真源，与 [dsh-translate-docs](../../../skills/dsh-translate-docs/SKILL.md) 和 i18n 契约之间的分工相同。
