/**
|
|
* The providerless, executor-less, UI-less agent spine as ONE bundle plugin.
|
|
*
|
|
* Loads the fixed set of services every harness agent needs — `timer`, the LLM
|
|
* service, the session store, system-prompt assembly, the tool registry, the
|
|
* agent registry, the dev-mode invariants, the model-facing `bash` tool
|
|
* schemas, project instruction loading, and the concrete `agent-loop` — and
|
|
* forwards the loop's `agents` list as its OWN config (default `[]`), so each
|
|
* app supplies its own pre-created agents.
|
|
*
|
|
* It is deliberately NOT the whole app: the swappable choices stay OUTSIDE the
|
|
* bundle, picked by whatever loads it.
|
|
* - the LLM ADAPTER (`llm-deepseek`/`llm-pi-ai`/`llm-replay`) — the bundle
|
|
* ships the abstract `llm` service + `tool-bash` consumer schema; the leaf
|
|
* registers a concrete adapter on `ctx.llm`.
|
|
* - the bash EXECUTOR (`bash-local` or a sandboxed impl) — the bundle ships
|
|
* the `bash` tool consumer; the leaf provides `ctx.bash`.
|
|
* - the PRESENTATION (stdio UI / ACP bridge / a logger) and the per-app infra
|
|
* (a console logger, `hmr`) — these are the coupled "front-door cluster" the
|
|
* app packages ({@link @deepseek-ai/dsh-stdio-agent},
|
|
* {@link @deepseek-ai/dsh-acp-agent}) bake in, NOT the shared spine.
|
|
*
|
|
* This is the interface/implementation/consumer seam at the composition level:
|
|
* the bundle owns the shared spine, the leaf owns the backends, the app package
|
|
* owns the front door. `timer` is in the spine (common to every front door — it
|
|
* writes nothing to stdout); the console logger is NOT (it writes to stdout,
|
|
* which the ACP bridge reserves for its JSON-RPC channel).
|
|
*
|
|
* Services register in the root store keyed by their isolate symbol, so a child
|
|
* loaded here via `ctx.plugin(...)` is visible to the bundle's SIBLINGS (the
|
|
* leaf's adapter and executor) exactly as a nested `plugin-include` subtree's
|
|
* services were before this bundle existed — cordis gates every read on
|
|
* `inject`, never on load order, so the fixed child set resolves regardless of
|
|
* which entry loads first.
|
|
*
|
|
* Plugin export shape: named `name`/`Config`/`apply`, NO default export — the
|
|
* cordis Loader's `unwrapExports` does `exports.default ?? exports`, so a stray
|
|
* default would collapse the module to the bare `apply` function and drop the
|
|
* `Config` schema (see docs/postmortem/0001). The keyless Loader-path smokes in
|
|
* the app packages guard this end-to-end.
|
|
*
|
|
* @module @deepseek-ai/dsh-agent-core
