+`dsh` starts the Host source through tsx, so the Host can use the SRC fallback; `dev:web` watches only Client plugins with a `dsh.client` declaration and rewrites their `lib/client.js`. It does not analyze Host decorators or generate Remote Client DTS.

 Changing only a Remote method's implementation body without changing its contract does not require regenerating the TypeRT files. After adding or removing a decorator or changing an export name, namespace, parameter, return value, lookup, Context, or cancellation signature, rerun the ordered lib build so the Host generates the strict contract before the Client compiles and bundles the new contribution:

 只修改 Remote 方法实现体而不改变约定时，无需重新生成 TypeRT 文件。新增或删除 decorator、修改导出名、namespace、参数、返回值、lookup、Context 或取消签名时，重新执行有序 lib 构建，让 Host 先生成严格约定，再让 Client 编译并打包新的贡献：

Package resolution anchors at the config tree's `ctx.baseUrl` — the cordis.yml directory, whose package declares every composed plugin as a dependency — and construction throws when that anchor is unset.

 Scanning is incremental per package; there is no full-rescan code path. Every cordis `internal/plugin` emission (fiber construction or disposal) marks the fiber's entry name dirty, and a microtask flush reconciles each dirty name against the live loader entries. The activation pass seeds the same dirty set with all current entries and flushes synchronously, so first scan and steady state share one implementation — with opposite failure postures. At activation, a malformed declaration or missing bundle among the already-loaded entries aggregates into one loud `AggregateError` listing every broken package: the fiber FAILS and the boot's fail-loud sweep reports it. In steady state, a broken package logs a warning and must not poison the others.
