imccyu 6dde9f70f0 fix: satisfy doc gates after the examples/ relocation
Repair cross-group README links whose targets changed groups
(ui/jsonrpc, ui/app-boot -> examples; examples/* -> ui seams),
re-record the bilingual-pair consistency hashes for the docs the
rename touched on both language sides, and condense the AGENTS.md and
packages/README.md group entries. The packages/README ceiling rises
710 -> 760 for the mandated new examples/ hierarchy row (5% headroom).

# `@deepseek-ai/dsh-app-boot`
Shared boot glue for the app bins ([`dsh-stdio-demo`](../../examples/stdio-demo/README.md), [`dsh-acp-demo`](../../examples/acp-demo/README.md)): each bin is a thin self-executing composition over these helpers, parameterized by its diagnostic prefix, so the loader-failure lore lives once — under the per-file coverage gate — instead of drifting between two published artifacts.
| Export | Role |
|---|---|
| `resolveConfigPath(path, snapshotMode, cwd?)` | Absolute config path; `snapshotMode === 'replay'` swaps a `cordis.yml`/`.yaml` basename for its sibling `cordis.snapshot.yml` |
| `loadEnv(binName, dir?, warn?)` | Load the gitignored `.env` (Node `process.loadEnvFile`); absent file is fine, an unloadable one warns a single labelled line (default: stderr) |
| `installFailLoud(binName, proc?)` | Turn a post-`boot()` unhandled Loader rejection into one labelled stderr line + `exit(1)`; returns the uninstaller (for tests) |
| `assertEntriesLoaded(ctx, binName)` | Throw when a settled tree holds an enabled entry with no fiber (a plugin module that failed to import) |
| `boot(binName, absoluteConfigPath)` | Mount the Loader, mount the statically imported include plugin as the `cordis:include` builtin (so the config may live outside `node_modules` reach), include the config by absolute `file://` URL, await the whole tree, assert entries loaded, return the root context |
Two failure classes the guards handle: `loader.await()` swallows init rejections (`Promise.allSettled`) — Node still exits non-zero on the resulting unhandled rejection, and `installFailLoud` replaces the noisy dump with one labelled line and a guaranteed `exit(1)`; a failed plugin IMPORT is only logged by the Loader (the process would otherwise exit 0 on a usable config typo), leaving a fiber-less entry that `assertEntriesLoaded` turns into a `boot()` rejection.
Bare plugin specifiers in a config (`@deepseek-ai/dsh-*`) resolve through the cordis Loader's internal module loader, using `node --expose-internals` or the optional `node-addon-require-builtin` fallback. the bins' subprocess smokes exercise that path, while this package's unit suite drives `boot()` in-process against configs with relative specifiers.
## Model Experience
Indirectly, through the plugin tree it loads, which determines the prompts, schemas, messages, and model adapter in the resulting application.
## Known Limitations and Deferred Work
- **Bare package specifiers depend on Loader internals** — production bins need `node --expose-internals` or the Loader's optional native fallback; an in-process caller without either must use resolvable relative/file specifiers or tsx path mapping.
- **Snapshot replay swapping is basename-specific** — only a config ending in `cordis.yml` or `cordis.yaml` maps to the sibling `cordis.snapshot.yml`; custom config names require caller-managed selection.
- **Environment loading is cwd-scoped and optional** — the helper loads one `.env` file and warns on failure; it does not search parents, merge profiles, or validate required variables.
