# Agent Note: One shared base config with per-surface overlays
Status: implemented
English | [中文](2026-07-29-shared-base-config-overlays.zh.md)
## Problem
`dsh` shipped two full config trees that were 43 rows the same. `apps/cli/cordis.yml` composed the web surface as 74 flat rows, while the TUI booted `examples/tui-agent/cordis.yml`, whose single `@deepseek-ai/dsh-tui-demo` row mounted twelve plugins and re-declared their configuration as its own twenty-key pass-through `Config`.
Neither file was what its location claimed. `examples/tui-agent` was not an example: `apps/cli/src/tui.ts` hardcoded it as the product's default config, and it owned the TUI PTY smoke, the eight terminal snapshot scenarios, and the PTY harness the `cordis-agent` leaf imported. `dsh-tui-demo` was not a demo either — it was the application, mounted by the shipped binary from `packages/examples/`.
The duplication was the load-bearing problem. Of the 43 shared rows, 38 were byte-identical and 5 differed for a defensible per-surface reason, so every capability change had to be made twice and could silently drift. The bundle also inverted a default: `composeTuiApp` read `config.goals ?? {}`, so the shipped TUI mounted goals, `tool-goal`, `goal-session`, and `/goal` although no config key requested them.
## Decision
One shared base, one overlay per surface, composed as sibling patch lists.
`apps/cli/config/base.cordis.yml` holds the 43 rows both surfaces mount. `apps/cli/config/tui.cordis.yml` and `apps/cli/config/web.cordis.yml` are **patch lists**, not trees: each states the handful of rows whose value is surface-specific and inserts its own rows. The launcher includes the base once and applies every overlay as a sibling patch list at **one** include level, because include patches never cross an include boundary — stacking overlays as nested includes would silently stop reaching base rows.
Precedence is list order, last write winning per row: base, then the surface overlay, then either a `--config` overlay or the personal `~/.dsh/config.yaml`, then the launcher's own flag and profile patches.
`--config <path>` now applies an overlay **instead of** the personal overlay, so a demo or test tree never inherits the user's provider and model. `--config-replace <path>` boots a file as the entire tree, bypassing base, surface overlay, and personal overlay alike; that is what the old `--config` did, so trees like `examples/web-cordis` moved to the new flag. Both flags survive the `/resume` execve handoff, or resuming would silently change the agent.
A patch replaces its target row's whole `config` rather than merging, which shapes the split: a row whose value differs per surface lives in the overlays, never in the base, so no row is patched by three layers at once. Session identity therefore cannot ride a config key at all — it moved to `dsh-agent-loop`'s `CONFIGURED_AGENT_IDENTITIES_KEY`, as [the launcher-owned identity note](../architecture/2026-07-28-launcher-owned-resume-identity.md) now records.
`examples/tui-agent`, `examples/cordis-agent`, `examples/code-mode`, and `packages/examples/tui-demo` are deleted. The TUI tests move to `apps/cli/tests/`, the cordis-toolset e2e to `packages/cordis/tool-cordis/tests/`, and the supported Code Mode demo remains the ACP overlay at `examples/acp-agent/code-mode.cordis.yml`.
## Alternatives considered
**Leave both trees flat and duplicated.** Rejected: 43 rows maintained twice is the defect, and a gate asserting they stay identical would freeze the duplication rather than remove it.
**Nest the overlays as includes (`code-mode` → `tui` → `base`).** Rejected after testing the Loader: patches do not cross an include boundary, so the outer file's patches are dropped with only a warning. A three-level chain left `tools` unpatchable, and a base behind one include made every personal patch a silent no-op.
**Put the union of all rows in the base and have each overlay disable what it does not want.** Rejected: the base stops meaning "shared", and each surface carries rows it exists only to switch off.
**Keep the per-surface rows in the base and let overlays patch them.** Adopted only for the five rows that must exist in both trees, because a patch cannot create a row. Their base entries carry the plugin name and the config both surfaces share; each overlay states the rest.
## Consequences
An overlay or `--config` tree that named `@deepseek-ai/dsh-tui-demo`, or patched the `tui-agent` row, no longer resolves. Overlays now patch the row that owns each key: the model route on `agent-loop`, the persona on `system-prompt`, presentation on `tui`.
A patch whose `id` matches no row stays a no-op rather than an error. That is deliberate: one personal overlay is shared across surfaces, and `insert` rows match nothing by design, so a row that exists only under `web` must not fail the TUI's boot.
`dsh web` gains `--config`, threaded into `AppCLIEntry` as an extra overlay. Web keeps sandboxed Bash and filesystem providers plus approval, permission presets, directory picking, and browser permission UI; the overlay disables the shared local providers because patches can disable rows but cannot delete them. The TUI query index uses a unique process-local temporary database because the SQLite backend requires one writer owner. It is a disposable derived index rebuilt by each process; `/resume` lists the underlying corpus directly and does not depend on index reuse. `AppCLIEntry` reads both the base and its surface overlay when recovering row defaults for its own patch merge, since a flag override must preserve the overlay's other fields on the same row.
## Verification
Composition is checked by booting each tree through the real Loader and inspecting settled entries, not by reading YAML; both surfaces settle with zero unloaded rows, and Web starts its `httpServer` with sandboxed Bash and filesystem providers. Code Mode remains covered by the ACP overlay and programmatic TUI snapshots rather than a separate shipped TUI application.
All eight terminal snapshot scenarios replay byte-identically after moving, and the 14-case PTY smoke passes, including two cases that assert a personal overlay reaches an **inserted** row — the behavior the vendored `plugin-include` fix enables ([`vendor/README.md`](../../../../vendor/README.md) local modification 8, covered by `packages/ui/app-boot/tests/config-reload.spec.ts`).
Flattening surfaced three latent defects, each fixed here: the TUI captured the optional `sessionQuery` service once at construction and so could permanently disable `/resume` when it won the mount race; the shipped session-store root silently reverted to a project-local `./.sessions`; and `--config-replace` was dropped by the resume handoff.

# Agent Note: 一份共享 base 配置加各 surface 的 overlay
Status: implemented
[English](2026-07-29-shared-base-config-overlays.md) | 中文
## 问题
`dsh` 交付了两棵完整的配置树,其中 43 个配置项完全相同。`apps/cli/cordis.yml` 以 74 个平铺配置项组合 web surface,而 TUI 启动的是 `examples/tui-agent/cordis.yml`——其中单独一行 `@deepseek-ai/dsh-tui-demo` 挂载了十二个插件,并把它们的配置重新声明为自己那份二十个键、仅作透传的 `Config`。
这两份文件都名不副实。`examples/tui-agent` 并不是示例:`apps/cli/src/tui.ts` 把它硬编码为产品的默认配置;它还拥有 TUI 的 PTY 冒烟测试、八个终端快照场景,以及被 `cordis-agent` 叶节点 import 的 PTY harness。`dsh-tui-demo` 也不是 demo——它就是应用本身,由交付的二进制从 `packages/examples/` 中挂载。
真正决定性的问题是重复。43 个共享配置项中,38 个逐字节相同,5 个因各 surface 的正当理由而不同;因此每次能力改动都必须改两处,而且可能无声漂移。该组合包还反转了一个默认值:`composeTuiApp` 读取 `config.goals ?? {}`,于是交付的 TUI 挂载了 goals、`tool-goal`、`goal-session` 和 `/goal`——尽管没有任何配置键要求它们。
## 决策
一份共享 base,每个 surface 一份 overlay,以平级 patch 列表的形式组合。
`apps/cli/config/base.cordis.yml` 持有两个 surface 都会挂载的 43 个配置项。`apps/cli/config/tui.cordis.yml` 与 `apps/cli/config/web.cordis.yml` 是 **patch 列表**,不是配置树:各自声明少数取值因 surface 而异的配置项,并 insert 自己的配置项。启动器只 include base 一次,并把每个 overlay 作为**同一** include 层级上的平级 patch 列表应用——因为 include patch 不会跨越 include 边界,把 overlay 堆叠成嵌套 include 会使其静默地无法触达 base 配置项。
优先级即列表顺序,逐配置项后写者胜:base,然后是 surface overlay,接着是 `--config` overlay 或个人 `~/.dsh/config.yaml`,最后是启动器自身的 flag 与 profile patch。
`--config <path>` 现在应用一个 overlay 来**取代**个人 overlay,因此 demo 或测试用的树绝不会继承用户的 provider 与 model。`--config-replace <path>` 则把某个文件作为整棵树启动,同时绕过 base、surface overlay 与个人 overlay;这正是旧 `--config` 的行为,所以像 `examples/web-cordis` 这样的树改用了新 flag。两个 flag 都会在 `/resume` 的 execve 交接中保留,否则 resume 会静默更换 agent。
patch 会整体替换目标配置项的 `config` 而不合并,这决定了拆分方式:取值因 surface 而异的配置项住在 overlay 中,绝不住在 base 里,从而没有任何配置项会被三层同时 patch。因此会话身份根本不能经由配置键传递——它迁移到了 `dsh-agent-loop` 的 `CONFIGURED_AGENT_IDENTITIES_KEY`,如[启动器持有身份的 note](../architecture/2026-07-28-launcher-owned-resume-identity.md) 现在所记录。
`examples/tui-agent`、`examples/cordis-agent`、`examples/code-mode` 与 `packages/examples/tui-demo` 均被删除。TUI 测试迁往 `apps/cli/tests/`,cordis 工具集的 e2e 迁入 `packages/cordis/tool-cordis/tests/`,受支持的 Code Mode demo 则保留为 `examples/acp-agent/code-mode.cordis.yml` 中的 ACP overlay。
## 备选方案
**保留两棵平铺且重复的树。** 拒绝:43 个配置项维护两份正是缺陷本身,而用一个门禁断言二者保持一致只会固化重复,而非消除它。
**把 overlay 嵌套成 include(`code-mode` → `tui` → `base`)。** 在对 Loader 实测后拒绝:patch 不会跨越 include 边界,因此外层文件的 patch 只会伴随一条告警被丢弃。三层链条使 `tools` 无法被 patch,而位于一层 include 之后的 base,会让每个个人 patch 都变成静默的空操作。
**把所有配置项的并集放进 base,由各 overlay 禁用自己不需要的部分。** 拒绝:base 将不再意味着「共享」,而每个 surface 都要携带仅为将其关闭而存在的配置项。
**把因 surface 而异的配置项留在 base 中,由 overlay 去 patch。** 仅对必须同时存在于两棵树中的那五个配置项采用,因为 patch 无法创建配置项。它们在 base 中的条目携带插件名与两个 surface 共享的配置,其余部分由各 overlay 声明。
## 影响
指名 `@deepseek-ai/dsh-tui-demo`、或 patch `tui-agent` 配置项的 overlay 与 `--config` 树将不再可解析。overlay 现在要 patch 拥有对应键的那一行:模型路由在 `agent-loop`,人设在 `system-prompt`,呈现设置在 `tui`。
若某个 patch 的 `id` 不匹配任何配置项,Loader 仍只告警而不报错。这是有意为之:同一份个人 overlay 会跨 surface 共用,而 `insert` 配置项按设计本就不匹配任何目标,因此仅在 `web` 下存在的配置项不能让 TUI 启动失败。
`dsh web` 新增 `--config`,作为一份额外 overlay 传入 `AppCLIEntry`。Web 保留沙箱化 Bash 与文件系统提供方,以及审批、权限预设、目录选择和浏览器权限界面;覆盖层会禁用共享的本地提供方,因为补丁可以禁用条目但不能删除条目。TUI 查询索引使用进程唯一的临时数据库,因为 SQLite 后端要求单写入者所有权。该索引是每个进程重新构建的可丢弃派生数据;`/resume` 直接列出底层语料,不依赖索引复用。`AppCLIEntry` 在为自身 patch 合并恢复配置项默认值时会同时读取 base 与其 surface overlay,因为 flag 覆盖必须保留同一配置项上 overlay 的其他字段。
## 验证
组合的正确性通过用真实 Loader 启动每棵树并检查已就绪的条目来核对,而不是靠阅读 YAML:两个界面都能稳定完成且没有未加载项;Web 会以沙箱化 Bash 与文件系统提供方启动 `httpServer`。Code Mode 继续由 ACP overlay 与程序化 TUI 快照覆盖,而不再维护独立交付的 TUI 应用。
全部八个终端快照场景在迁移后逐字节重放一致,14 个用例的 PTY 冒烟测试全部通过,其中两个用例断言个人 overlay 能触达一个 **insert 进来的**配置项——这正是 vendored `plugin-include` 修复所启用的行为([`vendor/README.md`](../../../../vendor/README.md) 本地修改第 8 条,由 `packages/ui/app-boot/tests/config-reload.spec.ts` 覆盖)。
平铺过程暴露出三处潜伏缺陷,均在此一并修复:TUI 曾在构造时一次性捕获可选的 `sessionQuery` 服务,因此在挂载竞争中胜出时会永久禁用 `/resume`;交付的会话存储根目录曾静默退回项目本地的 `./.sessions`;`--config-replace` 曾在 resume 交接中被丢弃。

# Agent Note: Sidebar resize without a visible pill
Status: implemented
English | [中文](2026-07-30-sidebar-resize-without-visible-pill.zh.md)
## Problem
The AppFrame exposed identical floating pills on both column borders. The left pill added unnecessary visual weight beside primary navigation, but the sidebar's resize interaction remains useful.
## Decision
AppFrame keeps the sidebar's 8px resize hit strip, `col-resize` cursor, pointer capture, animation-frame throttling, and width updates, but does not generate the sidebar handle's pill pseudo-element. The details boundary retains both its hit strip and floating pill.
The layout component test continues to pin sidebar dragging and both handles' collapse lifecycle. A keyless browser scenario reads the generated pseudo-elements from the shipped composition and drags the invisible sidebar boundary to prove the interaction remains live.
## Alternatives considered
**Remove the sidebar drag interaction with the pill.** Rejected because the requested change is visual; removing a working geometry control would unnecessarily narrow the interaction.
**Keep the pill but reduce its emphasis.** A smaller or lower-contrast pill still leaves an unwanted object on the sidebar boundary.
## Consequences
The sidebar boundary is visually quiet while pointer resizing remains available from the boundary and retains the resize cursor. Unlike the details control, that interaction has no visible pill.

# Agent Note: 侧边栏缩放不显示胶囊
Status: implemented
[English](2026-07-30-sidebar-resize-without-visible-pill.md) | 中文
## 问题
AppFrame 在两个栏位边界都显示相同的浮动胶囊。左侧胶囊在主导航旁增加了不必要的视觉负担,但侧边栏的缩放交互仍有用。
## 决策
AppFrame 保留侧边栏宽 8px 的缩放命中条带、`col-resize` 光标、指针捕获、动画帧节流和宽度更新,但不再生成侧边栏手柄的胶囊形伪元素。详情栏边界同时保留命中条带和浮动胶囊。
布局组件测试继续固定侧边栏拖动行为,以及两个手柄随面板折叠时的生命周期。一个无密钥浏览器场景读取实际交付组合所生成的伪元素,并拖动不可见的侧边栏边界,证明该交互仍然有效。
## 曾考虑的替代方案
**随胶囊一并移除侧边栏拖动交互。** 不予采纳,因为本次要求只改视觉表现;移除正常工作的几何控制会不必要地缩减交互方式。
**保留胶囊,但降低其视觉强调。** 更小或对比度更低的胶囊仍会在侧边栏边界留下一个不需要的物体。
## 后果
侧边栏边界在视觉上保持简洁,同时仍可在边界处通过指针调整宽度,并保留缩放光标。与详情栏控件不同,该交互没有可见胶囊。
