Merge branch 'stack/agent-profiles-5-web-ui' into stack/agent-profiles-8-authoring

Authoring meets standing mounts: write() and remove() drop the standing
pointer so the NEXT session composes the edited roster, while every session
already joined keeps the generation it runs on — a superseded generation is
never disposed while the process lives. The settings-dialog golden re-records
with this layer's Agent Preset nav entry, which the incoming layer-3 record
had overwritten.

+# Agent Note: Per-preset standing mounts over a scope parent chain
+
+Status: implemented

+
+## Problem
+
+Per-session preset mounts made the model-facing registry surface per-agent while three independent host readers still assumed it was static: cold `session.history` found no presenters (every card silently degraded to the generic renderer — indistinguishable from "tool has no presenter"), the projections block dropped preset-registered keys (clients treat an omitted key as capability absence and CLEAR the row), and the TypeRT gateway resolved `goals` on the host root (`service-unavailable`). Patching each reader individually traded one silent degradation for another: resuming to reach presenters flipped the projections fold from detached to live and wiped the token counts instead.
+
+## Decision
+
+A preset is one composition per PROCESS, not one per session. The roster mounts it once under a synthetic standing scope; each agent joins by `setScopeParent(agentKey, standingKey)`. Two `dsh-scope` mechanisms carry everything: registration views walk the parent chain (`agent → preset → global`, nearest shadowing farthest), and scoped dispatch admits listeners tagged with an ancestor of the carrier key — upward only, so a sibling preset's listeners stay deaf.
+
+## Consequences
+
+Standing mounts fix the class, not the instances: the registrations a reader needs exist for the process lifetime, keyed by preset id, no agent required. What made it cheap
+
+- The stateful preset plugins (`plan-mode`, `token-meter`, `compact-basic`, `tasks-local`) already key state by `Session`/`Agent` — they predate presets. Sharing one instance is a return to their design, not a rewrite.
+- Preset ymls are unchanged: one mount per preset = one Entry per preset, whose entry-local realms (`isolate: <name>: true`) keep two presets' same-named services apart exactly as they kept two sessions' apart.
+- A shared realm label was NOT an option: `provide()` throws on a second registration under the same realm symbol, so labels pool the REALM, never the instance — a per-session world sharing a label crashes the second mount.
+
+## Load-bearing details
+
+- **Standing mounts hang off the service's untraced `selfCtx`.** A method invoked through the traceable proxy sees `this.ctx` rebound to the caller with a shadow; reflect resolution for every fiber in a subtree minted from it starts at the shadow's fiber, so entries fail on services their own `inject` declares (`cannot get property "tools" without inject` while the entry's store holds it). The `tasks-local` selfCtx precedent, now with a second consumer.
+- **A settled mount is permanent for the process.** The composition a running session joined must survive its file changing or disappearing; deletion and edits reach only future generations (the authoring layer swaps the map pointer, never disposes a joined generation), and superseded generations are reclaimed only by whole-tree teardown — deliberate, bounded by edit frequency, recorded in the package's Known Limitations.
+- **`peek()` stays chain-blind.** Restrictions and guards address one scope's own contributions; only registration VIEWS inherit. Restrictions along the chain intersect (any scope may mask a global-surface name for everything nested inside it).
+- **Re-linking a key (`setScopeParent` on a live agent) is the blank-session recompose path** — valid only while nothing produced under the old parent is retained, which the caller must uphold; the relation cannot see session logs.
+
+## Alternatives considered
+
+Resume-on-read (wipes detached projections), a host-plane presenter table plus a block completeness flag (fixes two readers, leaves the class), per-session template mounts (duplicates every instance to serve pure functions). Kept for the record: the gateway-facing `goals` domain stays host-plane regardless — a Remote method whose receiver comes from a generated descriptor resolves on the host, which is the `bash-env` host-plane criterion read from the consuming side.

+
+Status: implemented

+
+## Problem
+
+按会话挂载 preset 让面向模型的注册面变成按 agent 的，而三个独立的宿主读取方仍然假设它是静态的：冷读 `session.history` 找不到 presenter（每张卡都静默退化成通用渲染器——与「工具本无 presenter」无法区分）、投影块丢掉 preset 注册的键（客户端把缺失键当作能力不存在并**清掉**该行）、TypeRT 网关在宿主根上解析 `goals`（`service-unavailable`）。逐个读取方打补丁只是拿一种静默降级换另一种：为拿到 presenter 而 resume，会把投影折叠从 detached 翻到 live，token 计数随之被抹掉。
+
+## Decision
+
+一个 preset 是**每进程**一份组装，而不是每会话一份。roster 在一个合成常驻 scope 下挂载它一次；每个 agent 通过 `setScopeParent(agentKey, standingKey)` 加入。两条 `dsh-scope` 机制承载了一切：注册视图沿父链解析（`agent → preset → global`，近者遮蔽远者），带作用域的分发对标签为载体键祖先的监听器放行——只向上，兄弟 preset 的监听器保持失聪。
+
+## Consequences
+
+常驻挂载修的是这一类问题而非其中的个例：读取方需要的注册在进程生命周期内始终存在，按 preset id 索引，不需要任何 agent。让它便宜的原因：
+
+- 有状态的 preset 插件（`plan-mode`、`token-meter`、`compact-basic`、`tasks-local`）本就按 `Session`/`Agent` 分键存状态——它们早于 preset 存在。共享一份实例是回归其设计，不是改写。
+- preset 的 yml 不变：每 preset 挂一次 = 每 preset 一个 Entry，其 entry 本地 realm（`isolate: <name>: true`）让两个 preset 的同名服务互不相干，正如它从前隔开两个会话。
+- 共享 realm label **不是**选项：`provide()` 对同一 realm 符号下的第二次注册直接抛错，label 池化的是 REALM 而非实例——按会话挂载的世界里共享 label 会让第二次挂载崩溃。
+
+## Load-bearing details
+
+- **常驻挂载挂在服务未追踪的 `selfCtx` 上。** 经 traceable 代理调用的方法看到的 `this.ctx` 被重绑到调用方并携带 shadow；从它派生的子树里每个 fiber 的 reflect 解析都从 shadow 的 fiber 起步，entry 会在自己 `inject` 声明的服务上失败（`cannot get property "tools" without inject`，而它的 store 里明明有）。`tasks-local` 的 selfCtx 先例，如今有了第二个消费者。
+- **挂载一旦成功即进程级永久。** 运行中会话加入的组装必须在其文件被修改或删除后继续存活；删除与编辑只影响未来的代际（创作层替换 map 指针，绝不 dispose 已被加入的代际），被替代的代际只由整树卸载回收——刻意为之，上限取决于编辑频率，已记入包的 Known Limitations。
+- **`peek()` 保持不看链。** 限制与守卫定位的是单个作用域**自己**的贡献；只有注册**视图**沿链继承。链上的限制求交（链上任一作用域都可为嵌套其内的一切遮蔽某个全局面名字）。
+- **对活 agent 重新认父（`setScopeParent`）是空白会话 recompose 的路径**——仅当旧父之下的产出一概不被保留时才合法，由调用方保证；该关系看不见会话日志。
+
+## Alternatives considered
+
+冷读时 resume（抹掉 detached 投影）、宿主面 presenter 表加投影块完整性标志（修两个读取方、留下这一类）、每会话模板挂载（为了服务纯函数而复制每一份实例）。留档：面向网关的 `goals` 域无论如何留在宿主平面——Remote 方法的接收者来自生成的 descriptor、在宿主上解析，这正是 `bash-env` 宿主平面判据从消费侧读出的样子。
