+### 3.6 `adapters/deepseek-harness/`
+
+Native Cordis plugin installed as an out-of-tree DSH bundle. It imports
+`MemoryCore` directly and provides:
+
+- `cordis.patch.yml` — bundle layer declared by `package.json`'s
+  `dsh.bundle.patch` field.
+- `index.ts` — Cordis configuration, DSH service injection, lifecycle hook
+  registration, `DSH_HOME`-aware runtime bootstrap, same-process Viewer
+  startup, and ordered disposal.
+- `bridge.ts` — correlates DSH turns, assistant output, native/code-mode tools,
+  and session disposal with `MemoryCore` DTOs. It deliberately does not
+  register a `session/flush` hook, so DSH flushes never create a MemOS capture
+  barrier.
+- `host-llm.ts` — adapts MemOS completions to DSH's public streaming LLM
+  service and isolates each turn's provider/model route with async-local state;
+  credentials remain owned by DSH.
+- `tools.ts` — six explicit `memos_*` tools using the same
+  `agentPreset`-aware namespace as automatic recall and capture.
+
+Every accepted, non-empty direct-user DSH turn performs one automatic recall.
+Re-entry in the same logical turn is de-duplicated, but prior session history
+does not suppress a new turn; greetings have no special case. Plugin and tool
+messages do not trigger automatic recall. The model can additionally use the
+explicit `memos_search` tool for a shorter, reformulated, or scoped lookup.
+
+The DSH foreground boundary is retrieval and context assembly for the current
+accepted query. The bridge returns the direct query before the source-labeled
+`memos-local-memory` context, but other DSH context contributions may sit
+between them. DSH still awaits `agent/pre-step` before it emits the canonical
+user event, so the query can remain unrendered until its own bounded recall
+completes; the adapter controls final message ordering, not host-side
+optimistic rendering.
+
+Turn routing (relation, intent, and episode) followed by capture runs in a
+per-session serial background queue. Neither a later `agent/pre-step`,
+`session/flush`, nor session disposal joins that queue. Session disposal only
+marks the session closing and detaches its route; queued work is retained for
+the later Cordis shutdown drain. Completed output becomes available to later
+automatic recalls and memory-tool calls. The immediately following turn never
+waits for that queue and can observe the older committed state if its own recall
+or tool search runs too soon.
+
+Automatic recall and explicit `memos_search` receive the same absolute core
+deadline: `min(recallTimeoutMs, 3000)` ms. The default is 3,000 ms, and the
+configuration may shorten but cannot extend this DSH foreground bound. DSH
+retrieval filtering sets malformed-JSON retries to zero; a
+malformed response, provider failure, or cancellable deadline abort returns the
+mechanical `safeCutoff` when ranked candidates exist. Without candidates,
+automatic recall injects nothing and explicit search returns an empty result.
+The adapter's hard guard uses that same effective budget. If native work
+cannot be cancelled immediately, automatic recall preserves the original
+pre-step decision and `memos_search` returns an empty result marked
+`timedOut: true`; the late work may still finish warming the shared cache.
+
+This per-turn recall, deadline, and malformed-output policy is adapter-scoped.
+OpenClaw and Hermes retain their existing foreground ordering, retrieval, and
+retry behavior.
+
+When `viewerEnabled` is true, the adapter starts the shared HTTP/SSE server
+against its in-process core and serves the packaged Viewer on
+`127.0.0.1:<viewerPort>` by default (`18801`). Cordis disposal stops new memory
+work, closes the server, then attempts a bounded, best-effort drain of the
+adapter bridge before shutting down the core. The DSH adapter opts into
+active-SSE termination during server close so an open Viewer tab cannot consume
+DSH's bounded disposal window; OpenClaw and Hermes retain their existing
+default drain policy. The Viewer and plugin have no independent process and
+exit with DSH. A transient
+`EADDRINUSE` during a quick restart gets a finite background retry, so ordinary
+one-`Ctrl+C` restart flows require no special wait or shutdown command. It
+starts no JSON-RPC bridge or sidecar process. See its [installation and
+lifecycle guide](./adapters/deepseek-harness/README.md).
+Its config-aware prompt guidance omits disabled tool hints and treats recalled
+context as untrusted historical data, not as instructions.
+An empty MemOS `llm.provider` is resolved to this host bridge; an explicit
+provider remains unchanged and can use the bridge as its configured fallback.
+
+On normal `Ctrl+C`/`SIGINT` or `SIGTERM`, the bridge closes its intake before
+the Viewer, queued work receives only the remaining bounded Cordis window, and
+the in-process plugin and Viewer exit with DSH. A second signal, `SIGKILL`, a
+process crash, terminal loss outside host disposal, or shutdown-budget expiry
+can leave background work unfinished. Because DSH does not replay the original
+`session/event` stream after restart and MemOS has no durable host receipt,
+such a turn can remain uncaptured.

+`lightweightMemory` narrows automatic, tool-driven, and sub-agent retrieval
+to trace-only Tier-2. Turn-start scheduling can also gate tiers for the
+classified scenario, so the table describes the normal full-memory plan.
 
 We do **not** silently inject context on every `onToolCall` / `onToolResult`.
 Those hooks are for observation only (failure counters, latency, event
 logging); any "injection" they produce is deferred to one of the triggers
 above — never mid-decision.
 
-This is implemented by three public entry points on `MemoryCore`:
+Adapters use the public `MemoryCore` facade rather than importing those
+internal retrieval functions directly. The relevant facade methods include:
 
 ```ts
 interface MemoryCore {
-  turnStartRetrieve(ctx: TurnStartCtx): Promise<InjectionPacket>;
-  toolDrivenRetrieve(ctx: ToolDrivenCtx): Promise<InjectionPacket>;
-  repairRetrieve(ctx: RepairCtx): Promise<InjectionPacket | null>;
-  // … plus turnEnd, feedback, skill invocation, etc.
+  onTurnStart(turn: TurnInputDTO): Promise<RetrievalResultDTO>;
+  prepareTurn?(turn: TurnInputDTO): Promise<{ sessionId: SessionId; episodeId: EpisodeId }>;
+  onTurnEnd(result: TurnResultDTO): Promise<{ traceId: string; episodeId: EpisodeId }>;
+  searchMemory(query: RetrievalQueryDTO): Promise<RetrievalResultDTO>;
+  timeline(input: { episodeId: EpisodeId; namespace?: RuntimeNamespace }): Promise<TraceDTO[]>;
+  recordToolOutcome(outcome: ToolOutcomeDTO): void;
+  // … plus listSkills, getSkill, feedback, and lifecycle methods.
 }
 ```
 
-`InjectionPacket` is defined in `agent-contract/dto.ts`; adapters decide how
-to splice it into their specific prompt shape.
+DeepSeek Harness uses `searchMemory({ reason: "turn_start", ... })` for pure
+prompt-time recall on every accepted, non-empty direct-user turn, with
+same-turn de-duplication. It then invokes the optional `prepareTurn()`
+capability in its background capture queue. Prior direct-user history does not
+suppress recall for a new turn. Existing adapters continue to use the composite
+`onTurnStart()` method and therefore retain their current ordering, waiting,
+deadline, and malformed-output semantics.
+
+The retrieval pipeline builds an internal `InjectionPacket`; the facade maps
+it to the DTO contract, and adapters decide how to splice the result into
+their host's prompt shape.
 
 ### 4.2 Happy path
 
+The diagram below is specifically the OpenClaw/Hermes composite
+`onTurnStart()` path. DeepSeek Harness does not follow its intent-before-recall
+ordering: as described in §3.6, every accepted direct-user DSH turn awaits only
+its own bounded retrieval/context assembly. DSH moves
+relation/intent/episode routing followed by capture to the per-session
+background queue, and the next turn never joins that earlier work.

+  bundle with capture, six memory tools, DSH profile-aware storage, and one
+  automatic recall for every accepted, non-empty direct-user turn. Same-turn
+  re-entry is de-duplicated, while greetings and restored-session turns receive
+  the same recall treatment as any other direct query. The bridge returns the
+  query before its source-labeled `memos-local-memory` context, although other
+  DSH context may appear between them. Automatic recall and explicit
+  `memos_search` share one absolute deadline (`min(recallTimeoutMs, 3000)` ms;
+  3,000 ms by default), and DSH retrieval filtering does not retry malformed
+  JSON. Malformed output, provider failure, or a cancellable timeout returns
+  the mechanical `safeCutoff` when ranked candidates exist; without candidates,
+  recall injects nothing and the tool returns an empty result. A wholly
+  non-cancellable provider hits the hard guard at the same effective budget:
+  recall preserves the pre-step decision and `memos_search` returns an empty
+  result marked `timedOut: true`. Relation/intent/episode routing followed by
+  capture (including summary and embedding writes) runs in a per-session serial
+  background queue. The next turn and `session/flush` never join prior
+  background work, while session
+  disposal detaches without joining; committed output becomes visible to later
+  automatic recalls and tool calls. These policies are DSH-specific and leave
+  OpenClaw and Hermes behavior unchanged. Clean Cordis disposal stops new

-`install.sh` creates a per-agent home folder for runtime state:

-Upgrading or uninstalling the plugin **never** touches `data/`, `skills/`,
-`logs/`, or `config.yaml`.
+An adapter creates only the directories it uses. DSH runs `MemoryCore` and the
+existing HTTP/SSE Viewer in the DSH Node.js process, without a JSON-RPC bridge
+or sidecar daemon. The Viewer listens on `http://127.0.0.1:18801` by default;
+set `viewerEnabled: false` in the DSH Cordis row to run without that listener.
+DSH still leaves MemOS file logging to the host, so its normal runtime surface
+is an optional `config.yaml`, `data/`, and `skills/` when skills are produced.

+Windows users can use DSH's lower-level `dsh plugin` flow.
+
+### DeepSeek Harness
+
+DSH support is an out-of-tree Cordis bundle. The one-command installer keeps
+DSH in control of its profile while handling pnpm's reviewed native dependency
+build policy non-interactively. If `pnpm` is not already on `PATH`, it prepares
+an isolated `pnpm@11.7.0` for that installer run without changing the user's
+global package-manager setup:
+
+```bash
+curl -fsSL https://raw.githubusercontent.com/MemTensor/MemOS/main/apps/memos-local-plugin/install.sh \
+  | bash -s -- --agent dsh --profile web --version 2.0.16
+```
+
+The installer delegates package ownership and bundle reconciliation to
+`dsh plugin`. If pnpm reports the reviewed build-script set, it enables
+`better-sqlite3`, `esbuild`, `onnxruntime-node`, and `sharp`, explicitly
+disables the unnecessary `protobufjs` and MemOS hint scripts, retries the same
+package spec, and verifies the composed `memos-local-memory` row. Any unknown
+build-script package fails closed for manual review; the installer never uses
+`approve-builds --all`.
+
+The temporary pnpm is removed when the installer exits. It is not needed for
+normal `dsh --profile ...` runtime use. Users who later run lower-level
+`dsh plugin` commands directly still need pnpm on `PATH`; install the DSH-pinned
+version persistently with `npm install -g pnpm@11.7.0` if desired.
+
+To develop from a local checkout instead, build it and add it to the desired
+DSH profile directly:
+
+```bash
+cd /path/to/MemOS/apps/memos-local-plugin
+npm install
+npm run build:package
+dsh plugin --profile web add .
+```
+
+The adapter reuses the provider/model and credentials already configured in
+DSH for MemOS auxiliary LLM calls by default; no second API key is required.
+For bounded structured helper calls it uses a model-advertised `off` reasoning
+effort when available, without changing the agent conversation's selection.
+An explicit MemOS LLM provider remains available as an override.
+
+Every accepted, non-empty direct-user DSH turn performs one automatic recall,
+including greetings; there is no greeting or intent-classification exception,
+and re-entry in the same logical turn is de-duplicated. The query is ordered
+before the source-labeled `memos-local-memory` context, although other DSH
+context contributions can appear between them. Restored sessions and forks
+follow the same per-turn rule, while plugin and tool messages do not
+trigger automatic recall. The model can additionally call `memos_search` for a
+shorter or reformulated lookup.
+
+Automatic recall and explicit `memos_search` share one absolute deadline:
+`min(recallTimeoutMs, 3000)` ms. The default is 3,000 ms, and configuration may
+shorten but cannot extend this DSH foreground bound. DSH retrieval
+filtering does not retry malformed JSON; malformed output, provider failure,
+or a cancellable timeout falls back to the mechanical
+`safeCutoff` over ranked candidates. With no ranked candidates, automatic
+recall injects nothing and the tool returns an empty result. A completely
+non-cancellable provider hits the hard guard at the same effective deadline;
+automatic recall preserves the original query path, while `memos_search`
+returns an empty result marked `timedOut: true`. DSH awaits `agent/pre-step`,
+so a query bubble can still appear only after that turn's bounded recall, but the
+final order remains query then context. Capture, relation, intent, summaries,
+and embeddings remain background work, and the next turn never waits for the
+previous turn's queue. These DSH-specific policies do not change OpenClaw or
+Hermes behavior.
+
+After the DSH profile starts, open the existing MemOS Viewer at
+`http://127.0.0.1:18801`. The server shares the adapter's in-process
+`MemoryCore`; it is not a second memory runtime or a sidecar process. The
+Cordis fields `viewerEnabled` and `viewerPort` control whether it starts and
+which port it uses; the shared `config.yaml` field `viewer.bindHost` defaults
+the bind interface to `127.0.0.1`. The DSH Viewer is currently supported for
+local-machine use only and accepts only `localhost` or an IPv4 `127.*`
+loopback address. A normal one-`Ctrl+C`/`SIGINT` or `SIGTERM` restart needs no
+MemOS-specific stop command or port wait: active Viewer SSE streams are closed,
+and a transient busy Viewer port retries in the background.

+# MemOS local memory for DeepSeek Harness
+
+This adapter loads `@memtensor/memos-local-plugin` as an out-of-tree
+[DeepSeek Harness](https://github.com/deepseek-ai/deepseek-harness) bundle. It
+adds one bounded automatic recall for every accepted direct-user turn,
+background capture, and on-demand memory tools to a DSH profile without
+modifying the DSH repository.
+
+> [!IMPORTANT]
+> DeepSeek Harness is currently a developer preview. The initial compatibility
+> target for this adapter is DSH `0.1.0-rc.5`; record the exact DSH version in
+> every release's validation because later preview releases may require adapter
+> changes. Unit compilation and contract tests currently use the published DSH
+> `0.1.0-rc.6` packages; the end-to-end host below is the rc.5 source checkout.
+
+## How it works
+
+The npm package declares a `dsh.bundle.patch`. When `dsh plugin` installs the
+package into a profile, DSH adds that patch to the profile's bundle stack and
+mounts the compiled adapter as a native Cordis plugin.
+
+```text
+DSH profile
+  └─ Cordis row: memos-local-memory
+       ├─ each accepted user turn ── bounded recall ──> MemoryCore
+       ├─ session/event ── enqueue route/classify → capture in background
+       ├─ dsh-llm ── auxiliary MemOS calls ──> active DSH provider/model
+       ├─ http/sse ── existing MemOS Viewer ──> 127.0.0.1:18801 (default)
+       ├─ session/flush ── no MemOS capture barrier
+       ├─ session/disposed ── detach without awaiting background work
+       ├─ Cordis dispose ── bounded best-effort drain and shutdown
+       └─ dsh-tools ── six explicit memory tools
+```
+
+Every accepted, non-empty direct-user DSH turn performs one automatic recall.
+The same logical turn is de-duplicated if DSH re-enters `agent/pre-step`, but
+there is no session-level bootstrap gate and no greeting or intent exception:
+`hello` is recalled exactly like any other non-empty direct-user query.
+Restored sessions and forks therefore recall for their next accepted turn
+regardless of prior direct-user history. Plugin-generated and tool messages do
+not trigger automatic recall. The static system-prompt guidance additionally
+lets the model call `memos_search` when a shorter or reformulated lookup would
+help.
+
+The foreground path performs only the retrieval needed to assemble recalled
+context. Automatic recall and explicit `memos_search` share one absolute
+deadline: `min(recallTimeoutMs, 3000)` ms. The default is 3,000 ms, and the
+configuration may shorten but cannot extend the DSH foreground bound. The DSH
+retrieval filter does not retry malformed JSON; a malformed
+response, provider failure, or deadline abort falls back to the mechanical
+`safeCutoff` over the already-ranked candidates. If no ranked candidate exists,
+automatic recall injects no context and `memos_search` returns an empty result.
+If a provider ignores cancellation entirely, the adapter's hard guard uses the
+same effective budget instead of extending foreground work indefinitely;
+automatic recall keeps the original pre-step decision, while `memos_search`
+returns `hits: []`, `timedOut: true`, and
+`text: "No relevant memories found."`. This path never joins any pending capture,
+summary, embedding write, relation classification, intent classification, or
+episode routing. Non-empty recall is capped, wrapped in `<memos_context>`, and
+appended after the direct query as a DSH user message whose source is
+`plugin/memos-local-memory/recall`. The resulting order is therefore query
+first, then the source-labeled MemOS context; adjacency is not guaranteed, and
+other DSH context contributions may appear between them in the UI.
+Plugin-generated messages are excluded from
+the query, so recall cannot recursively recall itself. The accompanying
+system-prompt guidance marks the block as untrusted historical data rather than
+instructions or authority.
+
+DSH awaits `agent/pre-step` before publishing its canonical user event, so each
+accepted query can wait for its own bounded recall before its bubble is
+rendered. The adapter controls the eventual query-before-context message order,
+not that host-side optimistic rendering behavior. No query waits for a prior
+turn's capture, relation, intent, summary, or embedding work; the next turn
+starts its own recall immediately against the latest committed state.
+
+The adapter then aggregates DSH's structured assistant, native-tool, and
+code-dispatch events. At `turn/end` it puts relation/intent/episode routing and
+the following `MemoryCore.onTurnEnd()` capture in the same per-session serial
+background queue. Their committed results become available to later automatic
+recalls and explicit memory-tool calls. The immediately following turn never
+waits for that queue; if its own recall or tool search runs before those jobs
+commit, it sees the older committed state. DSH's awaited `session/flush` hook is deliberately
+not used as a MemOS capture barrier, and session disposal also does not join the
+queue. Only Cordis plugin disposal stops accepting new memory work and attempts
+a bounded, best-effort drain before shutting down the core.
+
+These foreground and retry policies are scoped to the DeepSeek Harness
+adapter. The OpenClaw and Hermes adapters retain their existing recall,
+ordering, deadline, and malformed-output behavior.
+
+By default, an otherwise-unconfigured MemOS LLM delegates auxiliary summary,
+reflection, and evolution calls to DSH's public `llm` service. The adapter
+captures the provider/model route for the owning turn and carries it through an
+async-local scope, so concurrent sessions cannot overwrite one another's
+route. Credentials remain inside DSH's provider adapter: MemOS neither reads
+the DSH API key nor asks the user to configure it a second time. An explicit
+MemOS `llm.provider` remains authoritative and can still fall back to DSH when
+`fallbackToHost` is enabled.
+
+MemOS filters and JSON extractors use deliberately small output caps. Before
+each auxiliary call, the bridge asks DSH's registration-bound `prepareCall()`
+to validate the branded `off` effort. A supported `off` disables reasoning for
+that helper request; an explicit unsupported-effort result is retried without
+an effort so the DSH adapter/provider keeps its own default. The returned
+prepared stream binds capability validation and dispatch to the same adapter
+registration across HMR. This does not change the agent conversation's
+selected reasoning level.
+
+This adapter runs `MemoryCore` and the existing MemOS HTTP/SSE Viewer in the
+DSH Node.js process. The Viewer is enabled by default at
+`http://127.0.0.1:18801` and shares that same core; the adapter does not start
+the MemOS JSON-RPC bridge or a sidecar daemon.
+
+## Install
+
+Prerequisites:
+
+- A Node.js version accepted by the DSH release. DSH `0.1.0-rc.5` requires
+  Node.js `^22.19.0 || >=24.0.0`; this stricter host requirement takes
+  precedence over the MemOS package's standalone `>=20` engine.
+- A working DSH installation. The recommended one-command installer prepares
+  an isolated `pnpm@11.7.0` for the install when pnpm is absent. Lower-level
+  direct `dsh plugin` commands still require pnpm on `PATH`.
+- A provider, model, and API credential already configured and verified with a
+  normal DSH prompt. Host delegation avoids configuring that credential again
+  in MemOS; it does not make an unconfigured DSH model route usable.
+- `@memtensor/memos-local-plugin` version `2.0.16` or newer.
+
+For a published package, the recommended macOS/Linux path is the one-command
+installer. It delegates to DSH rather than copying files into the profile:
+
+```bash
+curl -fsSL https://raw.githubusercontent.com/MemTensor/MemOS/main/apps/memos-local-plugin/install.sh \
+  | bash -s -- --agent dsh --profile web --version 2.0.16
+```
+
+The installer prepares an isolated `pnpm@11.7.0` when pnpm is absent, handles
+only the reviewed pnpm build-script set described below, retries the same
+registry or local-tarball spec, and verifies that DSH composed the bundle. The
+temporary pnpm is removed when the installer exits and does not change the
+user's global package-manager setup. It fails closed when the dependency graph
+introduces an unreviewed script. Restart the selected DSH profile after
+installation.
+
+### Install from a local checkout
+
+Build the package, then install its checkout into the DSH profile you use:
+
+```bash
+cd /path/to/MemOS/apps/memos-local-plugin
+npm install
+npm run build:package
+dsh plugin --profile web add .
+```
+
+`web` is the profile used for the validation below; replace it with the profile
+you actually run. `build:package` compiles both the adapter and the Viewer,
+while `dsh plugin` invokes
+the DSH profile's pnpm-based package installation.
+
+DSH anchors a local path to the directory where the command is invoked, so
+`add .` installs this checkout. If you run DSH from its source repository,
+use the DSH repository's launcher and an absolute plugin path instead:
+
+```bash
+cd /path/to/deepseek-harness
+pnpm dsh plugin --profile web add /absolute/path/to/MemOS/apps/memos-local-plugin
+```
+
+You can also test the exact built artifact that would be distributed:
+
+```bash
+cd /path/to/MemOS/apps/memos-local-plugin
+npm pack
+dsh plugin --profile web add /absolute/path/to/memtensor-memos-local-plugin-<version>.tgz
+```
+
+The lower-level registry form is:
+
+```bash
+dsh plugin --profile web add @memtensor/memos-local-plugin@<version>
+```
+
+Because lower-level `dsh plugin` calls do not pass through the MemOS installer,
+they require pnpm on `PATH`. To keep DSH's tested version available for those
+commands, install it persistently if needed:
+
+```bash
+npm install -g pnpm@11.7.0
+```
+
+### Review dependency build scripts
+
+The adapter entry point in a packed tarball is already compiled; it does not
+need a TypeScript `prepare` build inside the DSH profile. However, MemOS has
+native and generated-code dependencies whose own install scripts pnpm 11
+blocks until the profile owner approves them. A first tarball or registry
+install can therefore stop with `ERR_PNPM_IGNORED_BUILDS` even though the
+adapter itself is prebuilt.
+
+Read the package names in pnpm's error, inspect what each script installs, and
+approve only the dependencies you trust. `dsh plugin` forwards this command to
+`pnpm approve-builds` in the selected profile:
+
+```bash
+dsh plugin --profile web approve-builds
+```
+
+For the tested `2.0.16-beta.1` package, pnpm reported `better-sqlite3`,
+`esbuild`, `onnxruntime-node`, `protobufjs`, `sharp`, and the MemOS package's
+own postinstall hint. Review found that the
+required set was `better-sqlite3`, `esbuild`, `onnxruntime-node`, and `sharp`;
+`protobufjs` and the package's own postinstall hint were not needed. The
+equivalent reviewed profile policy was:
+
+```yaml
+# $DSH_HOME/profiles/web/pnpm-workspace.yaml
+allowBuilds:
+  '@memtensor/memos-local-plugin': false
+  better-sqlite3: true
+  esbuild: true
+  onnxruntime-node: true
+  protobufjs: false
+  sharp: true
+```
+
+Dependency sets can change by package version and platform, so use pnpm's
+current output as the source of truth; do not use `approve-builds --all` or
+copy this allowlist blindly. Install scripts execute with the current user's
+permissions, outside the agent tool sandbox. After approval, rerun the same
+`dsh plugin --profile web add ...` command so DSH can finish installation and
+reconcile the bundle layer.
+
+The one-command installer automates this exact reviewed policy only when the
+pending set contains no other package. Direct `dsh plugin add` users retain the
+manual review flow above.
+
+This branch pins Transformers.js to `4.2.0`; the tested lock and DSH profile
+resolve Transformers.js 4.2.0 with `onnxruntime-node` 1.24.3. The earlier
+Transformers.js 3.x / ONNX Runtime 1.21 combination has a [known macOS destructor
+crash](https://github.com/microsoft/onnxruntime/issues/24579), fixed by the
+upstream [environment-lifetime
+change](https://github.com/microsoft/onnxruntime/pull/26445), when a host calls
+`process.exit()` after inference; DSH's graceful signal path does exactly that.
+Do not downgrade this dependency in a DSH profile that uses local embeddings.
+
+Verify that DSH composed the bundle before booting it:
+
+```bash
+dsh --profile web --dump-config
+```
+
+The output should contain a bundle layer for
+`@memtensor/memos-local-plugin` and a row with `id: memos-local-memory`.
+
+### Restart requirement
+
+Adding, removing, or updating a bundle changes the profile's installed plugin
+set. Use DSH normally: one `Ctrl+C`/`SIGINT` in the foreground, or a normal
+`SIGTERM` from a process manager, then start the profile again. No MemOS-only
+shutdown command or extra wait is required:
+
+```bash
+dsh --profile web
+```
+
+When the profile is ready, open `http://127.0.0.1:18801` to inspect and manage
+the same memory used by automatic recall, capture, and the `memos_*`
+tools.
+
+A running DSH process does not discover a newly installed package. Restart
+after rebuilding a linked checkout as well, because imported modules are
+cached for the process lifetime. DSH can hot-reload valid edits to a profile's
+`cordis.patch.yml`, but restart after changing MemOS `config.yaml` to ensure
+the core is rebuilt with the new settings.
+
+## Uninstall
+
+Remove the package from each profile where it was installed, then restart
+that profile:
+
+```bash
+dsh plugin --profile web remove @memtensor/memos-local-plugin
+```
+
+This removes the dependency and bundle layer. It intentionally leaves the
+runtime home (`$DSH_HOME/memos-plugin/`, default
+`~/.dsh/memos-plugin/`) untouched so memories survive a reinstall. Back up
+and remove that directory separately only if you also intend to delete the
+stored memory.
+
+## Adapter configuration
+
+The bundle inserts the following Cordis row. To override it for the `web`
+profile, place a row with the same `id` in
+`$DSH_HOME/profiles/web/cordis.patch.yml` (by default,
+`~/.dsh/profiles/web/cordis.patch.yml`):
+
+```yaml
+- id: memos-local-memory
+  config:
+    enabled: true
+    profileId: default
+    home: ''
+    recallEnabled: true
+    captureEnabled: true
+    toolsEnabled: true
+    hostLlmEnabled: true
+    viewerEnabled: true
+    viewerPort: 18801
+    recallTimeoutMs: 3000
+    contextMaxChars: 6000
+    toolResultMaxChars: 1200
+    failOnStartupError: false
+```
+
+DSH patch layers replace the target row's complete `config` value rather than
+deep-merging keys, so keep every field when overriding one.
+
+| Field | Default | Meaning |
+| --- | --- | --- |
+| `enabled` | `true` | Mount or disable the adapter. |
+| `profileId` | `default` | Fallback namespace; a non-empty session `agentPreset` overrides it consistently for recall, capture, and tools. |
+| `home` | `''` | Empty means `$DSH_HOME/memos-plugin` (default `~/.dsh/memos-plugin`); otherwise an absolute or `~`-relative runtime root. |
+| `recallEnabled` | `true` | Run one automatic recall for every accepted, non-empty direct-user turn. Re-entry within the same logical turn is de-duplicated; there is no greeting or restored-session exception. |
+| `captureEnabled` | `true` | Capture completed DSH turns and tool outcomes. |
+| `toolsEnabled` | `true` | Register the six `memos_*` tools. |
+| `hostLlmEnabled` | `true` | Reuse the provider/model and credentials already configured in DSH for MemOS LLM work when `llm.provider` is empty; supported helper calls request reasoning `off`, and the bridge also supplies the configured host fallback. |
+| `viewerEnabled` | `true` | Serve the existing MemOS Viewer and its HTTP/SSE API in the DSH process. Set to `false` for a headless memory runtime with no Viewer listener. |
+| `viewerPort` | `18801` | Integer listener port (`1`–`65535`) for the DSH Viewer. Use a different port when another process or DSH profile already owns `18801`. |
+| `recallTimeoutMs` | `3000` | Requested deadline shared by automatic recall, explicit `memos_search`, and the adapter's hard fail-open guard; minimum `100`, with an effective DSH maximum of `3000`. Filter failures use `safeCutoff` when ranked candidates exist. |
+| `contextMaxChars` | `6000` | Maximum injected `<memos_context>` size; minimum `256`. |
+| `toolResultMaxChars` | `1200` | Maximum body size rendered by memory tools; minimum `128`. |
+| `failOnStartupError` | `false` | When `true`, an adapter startup error, including an enabled-Viewer bind failure, fails DSH profile boot. |
+
+### Runtime home and core configuration
+
+Runtime path precedence is:
+
+1. `MEMOS_HOME`
+2. `MEMOS_CONFIG_FILE` (its parent becomes the runtime root)
+3. the Cordis row's `home`
+4. `$DSH_HOME/memos-plugin` when `DSH_HOME` is set
+5. `~/.dsh/memos-plugin`
+
+The default layout is:
+
+```text
+$DSH_HOME/memos-plugin/            # ~/.dsh/memos-plugin when DSH_HOME is unset
+├── config.yaml       # optional MemOS core configuration
+├── data/memos.db     # SQLite memory and pipeline state
+└── skills/           # crystallized skill packages, when produced
+```
+
+On first boot, a missing `config.yaml` produces a warning and uses MemOS
+defaults. The default embedder is local; its model may be downloaded on first
+use. If that cold work exceeds the current request's deadline (3 seconds by
+default), MemOS uses `safeCutoff` when ranked candidates exist; if native work
+cannot be cancelled, the adapter continues without the late result while the
+load may finish in the background. Later automatic recalls or on-demand
+searches can then use the warmed model. Both the local provider and the DSH
+adapter enforce this fail-open boundary, so a cold Transformers load cannot
+extend the DSH foreground memory boundary beyond the configured
+`recallTimeoutMs`.
+
+With `hostLlmEnabled: true`, an empty `llm.provider` is resolved to the DSH host
+bridge, so no duplicate MemOS API key is needed after the DSH model route itself
+works. The bridge reuses DSH's provider/model route and credential
+resolution only; it sends a separate MemOS request and does not inherit the
+agent conversation, assembled system prompt, tools, agent reasoning selection,
+or agent-loop retry policy. For bounded structured helper calls it requests the
+model's declared `off` reasoning effort when available; this avoids spending a
+small JSON output budget on hidden reasoning. The agent's own selection is not
+modified.
+Those auxiliary requests consume the selected provider's normal quota and can
+incur cost or rate limits.
+The default lightweight pipeline uses that bridge for its summary call. To
+enable L2 policy induction, L3 world-model abstraction, and skill
+crystallization, set only:
+
+```yaml
+algorithm:
+  lightweightMemory:
+    enabled: false
+```
+
+In that opt-in full-memory mode, the adapter disables autonomous startup and
+10-minute dirty-episode recovery when the effective MemOS provider is `host`.
+Those jobs have no owning DSH request route, and borrowing a route from an
+unrelated session would cross a provider/privacy boundary. Turn capture,
+session finalization, tool feedback, and explicit memory tools still use the
+owning session's captured route. Configure a direct MemOS provider if
+autonomous full-memory recovery must perform LLM stages. The default
+lightweight mode keeps its local startup cleanup because that path does not run
+reward/evolution LLM work.
+
+You can still configure a direct MemOS provider. A non-empty `llm.provider` is
+never overwritten; when its `fallbackToHost` is true, eligible provider
+failures delegate to the same DSH bridge.
+
+| Adapter/model mode | Result |
+| --- | --- |
+| `hostLlmEnabled: true`, empty MemOS provider | Use the working DSH route and its credential resolution; no duplicate MemOS key. |
+| Explicit MemOS provider | Use that provider and its MemOS-side credential; optionally fall back to DSH. |
+| `hostLlmEnabled: false`, empty MemOS provider | Run without an LLM: basic/local memory remains available while model-assisted filtering, summaries, reflection, and evolution skip or use their documented fallback. |
+
+DSH does not currently expose provider-neutral forced JSON/schema output on its
+public LLM service. MemOS therefore supplies its JSON contract in the prompt
+and parses and validates the returned text locally. For DSH retrieval filtering,
+malformed JSON is not retried: the request immediately uses the mechanical safe
+cutoff. Other MemOS structured operations and the OpenClaw/Hermes adapters keep
+their existing policies. This is best-effort structured output rather than a
+provider-enforced schema.
+
+The core configuration schema is shared with the OpenClaw and Hermes adapters;
+see [`core/config/README.md`](../../core/config/README.md) and
+[`docs/CONFIG-ADVANCED.md`](../../docs/CONFIG-ADVANCED.md). If `config.yaml`
+contains credentials, make its permissions owner-only (`0600`).
+
+### Memory Viewer
+
+With `viewerEnabled: true`, the adapter starts the same Viewer and HTTP/SSE
+server used by the other MemOS local adapters:
+
+```text
+http://127.0.0.1:18801
+```
+
+The server is an in-process facade over the adapter's `MemoryCore`. It does
+not spawn another Node.js process, open the JSON-RPC bridge, or create a second
+database connection owned by a separate memory runtime. Cordis disposal stops
+accepting new memory work and Viewer requests, closes active SSE streams, then
+gives the bridge only the remaining bounded shutdown window to finish queued
+work before shutting down the core. The plugin and Viewer have no independent
+daemon: after DSH has exited, neither can remain running. Thus an open Viewer
+tab cannot consume DSH's bounded disposal window. This SSE-close policy is an
+explicit DSH adapter opt-in; the shared server keeps its existing drain
+behavior for OpenClaw and Hermes by default.
+
+Quick Viewer restarts are self-healing. If `viewerPort` is still transiently
+busy, recall, capture, and tools become available immediately while the adapter
+retries the Viewer bind five times over about 5.75 seconds. A successful retry
+restores the panel without another DSH restart.
+
+The bind host comes from the shared MemOS core setting
+`viewer.bindHost` and defaults to `127.0.0.1`; the Cordis `viewerPort` field
+owns the DSH port instead of `viewer.port` in `config.yaml`. DSH accepts only
+`localhost` or an IPv4 `127.*` loopback address for this setting.
+
+> [!WARNING]
+> The DSH Viewer currently supports local-machine use only. Keep
+> `viewer.bindHost: 127.0.0.1`. The adapter does not wire an HTTP API key into
+> the server, and Viewer password protection is off until an `.auth.json`
+> exists. A non-loopback value such as `0.0.0.0` or a LAN address is rejected
+> instead of exposing the read/write memory API. Do not place the loopback
+> listener behind a proxy, tunnel, or port forward.
+
+The Viewer is a standalone MemOS page and is not mounted inside DSH Web at
+port `3080`. If several DSH profiles run concurrently, give each enabled
+Viewer a distinct `viewerPort`, or leave the Viewer enabled in only one
+profile. Profiles that intentionally share a runtime home also share the same
+underlying memory, regardless of which profile serves the Viewer.
+
+DSH-specific lifecycle controls are deliberately narrower than OpenClaw and
+Hermes. Saving `config.yaml` from Viewer Settings reports that the active DSH
+profile must be stopped and restarted manually; the Viewer cannot restart its
+parent host. The DSH Viewer hides legacy-database migration and Clear Data.
+The server also rejects Clear Data while MemOS is embedded in a running DSH
+process, so back up or remove its database only while the profile is stopped.
+
+## Model-facing memory tools
+
+When `toolsEnabled` is true, the adapter registers:
+
+| Tool | Purpose |
+| --- | --- |
+| `memos_search` | Search skills, traces/policies, and world models; optionally restrict results to the current DSH session. |
+| `memos_get` | Fetch bounded details for one `trace`, `policy`, or `world_model` by ID. |
+| `memos_timeline` | Reconstruct the ordered traces for an episode. |
+| `memos_environment` | List or filter learned world/environment models. |
+| `memos_skill_list` | List candidate, active, or archived crystallized skills. |
+| `memos_skill_get` | Load one skill and record its use/trial against the active task. |
+
+The model decides when to call these tools. Per-turn automatic recall works
+independently of `toolsEnabled`; `memos_search` remains available for a shorter,
+rephrased, or explicitly scoped follow-up lookup. Automatic recall and
+`memos_search` use the same absolute deadline (`min(recallTimeoutMs, 3000)` ms)
+and DSH-specific no-malformed-retry filter policy. When tools
+are disabled, the system-prompt guidance omits the tool suggestion. Automatic
+recall, capture, and all explicit tools use the same `agentPreset`-aware
+namespace resolver.
+
+The default runtime home is shared across DSH profiles and the fallback
+`profileId` is `default`. If multiple profiles point at that same home and a
+session has no distinct `agentPreset`, they intentionally share a namespace.
+Set a unique `profileId` per profile (or a separate `home`) when that sharing is
+not desired.
+
+## Failure behavior
+
+Memory is optional to the host agent after Cordis has resolved and loaded the
+adapter:
+
+- A MemOS bootstrap failure inside `apply()` logs a warning and leaves DSH
+  running without this memory plugin when `failOnStartupError` is false.
+- Retrieval-filter failure or timeout returns `safeCutoff` when ranked
+  candidates are already available. Without ranked candidates, automatic
+  recall injects nothing and explicit `memos_search` returns an empty result.
+  If the provider is wholly non-cancellable, the hard guard fires at the same
+  effective deadline: automatic recall returns the original DSH pre-step
+  decision unchanged, while `memos_search` returns an empty result marked
+  `timedOut: true`.
+- Capture and tool-observation failures are logged and contained inside the
+  per-session write queue.
+- A Viewer bind or HTTP-server startup failure is logged and leaves recall,
+  capture, and memory tools running when `failOnStartupError` is false. This
+  includes a busy port and a non-loopback `viewer.bindHost`. A busy port gets a
+  finite background retry window for quick-restart overlap; persistent port
+  conflicts and invalid bind settings require correction before a later
+  profile restart. When
+  `failOnStartupError` is true, the same failure rolls back the MemOS runtime
+  and fails DSH profile boot.
+- `session/flush` does not wait for MemOS capture or classification work, so a
+  slow auxiliary model call cannot delay DSH's durability checkpoint or the
+  next agent request.
+- Context is bounded and explicitly described as untrusted historical data,
+  not instructions or authority. It may also be stale, so
+  correctness-sensitive facts should be verified.
+
+Set `failOnStartupError: true` in CI or controlled deployments where silently
+running without memory or the configured Viewer is worse than failing the
+profile boot. Invalid Cordis configuration, missing modules or peers, schema
+validation errors, and failures before `apply()` runs are ordinary DSH load
+errors and are not fail-open.
+
+## Privacy and security
+
+- Memory state is stored locally in the configured runtime home. With
+  `viewerEnabled: true`, the adapter exposes its read/write memory API and
+  Viewer on `127.0.0.1:<viewerPort>` (`18801` by default). Software and users
+  on the same machine can reach the listener. Viewer password protection is
+  off by default and can be enabled from its Settings page, but the current
+  DSH adapter does not support a remote bind. It rejects any `viewer.bindHost`
+  other than `localhost` or an IPv4 `127.*` address. Set `viewerEnabled: false`
+  when no local UI/API is wanted. No sidecar process is started.
+- Captured rows can include direct user text, assistant text and reasoning,
+  tool names/arguments/results, code-dispatch output, success/error metadata,
+  timestamps, and the session workspace path (`cwd`). Treat the SQLite file as
+  sensitive conversation and development data.
+- Recalled memory becomes part of the model prompt. It therefore reaches the
+  model provider selected by DSH, just like the user's current conversation.
+- MemOS auxiliary LLM prompts also reach the provider/model selected for that
+  DSH turn when `hostLlmEnabled` is on. The adapter passes a route, messages,
+  limits, a capability-checked `off` reasoning effort when available, and an
+  abort signal to DSH; it does not access provider credentials or alter the
+  agent conversation's reasoning setting.
+- Configuring a remote MemOS LLM, embedding provider, or Hub can send data to
+  that configured service. Review the core configuration before enabling one.
+- The DSH adapter does not construct a MemOS telemetry sender. DSH's own
+  telemetry settings remain independent of this plugin. In particular, DSH
+  `FULL` telemetry can export projected session events, including message and
+  tool data; review or disable DSH telemetry separately.
+- An out-of-tree Cordis bundle is trusted Node.js code running inside the DSH
+  process, outside the agent tool sandbox. Inspect the source, pin versions or
+  commits, and install only artifacts you trust.
+- Retrieved memory is historical data, not an instruction authority. Treat it
+  as untrusted and potentially stale, especially when it contains copied tool
+  output or repository text.
+
+## Known limitations
+
+1. **Developer-preview compatibility.** The initial compatibility target is
+   DSH `0.1.0-rc.5`; verify the packaged artifact against that exact host
+   before publishing results. Its optional DSH peer range is
+   `>=0.1.0-rc.5 <0.2.0`, but that range is not a guarantee across preview
+   breaking changes.
+2. **Eventual consistency and abrupt-crash replay gap.** Per-turn foreground
+   recall never waits for prior capture, relation, or intent work. A completed
+   background result is visible to later automatic recalls and explicit tool
+   calls only after it commits; the immediately following turn never waits for
+   that queue. On a normal `Ctrl+C`/`SIGINT` or `SIGTERM`,
+   Cordis disposal attempts a
+   best-effort drain within DSH's bounded plugin window (five seconds in
+   `0.1.0-rc.5`) and the in-process Viewer and plugin exit with DSH. A second
+   signal forces immediate exit. `SIGKILL`, a process crash, terminal-loss
+   shutdown without host disposal, or expiry of the budget can leave background
+   work unfinished. The OS releases sockets and SQLite recovers its WAL on the
+   next open, but a turn can remain uncaptured because restored DSH sessions do
+   not currently re-emit the original `session/event` stream and MemOS has no
+   durable host receipt to reconcile after restart.
+3. **Standalone Viewer only.** DSH serves the existing MemOS Viewer at
+   `127.0.0.1:<viewerPort>` by default; it is not embedded into the DSH Web UI
+   at port `3080`. Concurrent profiles cannot bind the same Viewer port, so
+   configure distinct ports or disable all but one Viewer. Browser cookies on
+   the same hostname are shared across ports: Viewers backed by different
+   runtime homes still use the same `memos_sess_deepseek-harness` cookie name,
+   so logging into one can overwrite the other's session. Prefer one enabled
+   DSH Viewer, or isolate them with separate browser profiles.
+4. **Best-effort JSON contracts.** DSH's public LLM service has no
+   provider-neutral forced JSON/schema option. MemOS validates prompt-guided
+   JSON locally and treats truncation, tool calls, empty text, or malformed
+   output as failures.
+5. **Pre-request route edge.** Each per-turn recall runs before DSH finalizes
+   that turn's `agent/request`. It therefore uses the latest persisted request
+   route when present, otherwise public agent defaults, and fails open when no
+   route exists. Turn-end capture refreshes from the now-persisted current
+   route.
+6. **Direct-user turns only.** Every accepted, non-empty query whose source kind
+   is `user` triggers one automatic recall, including greetings. Re-entry in the
+   same logical turn is de-duplicated; plugin and tool messages cannot trigger
+   it.
+7. **Background recovery has no owning route.** In opt-in full-memory mode,
+   startup stale/dirty recovery and the 10-minute dirty-episode rescore run
+   outside any DSH request scope. When the effective MemOS provider is `host`,
+   the adapter disables those autonomous jobs instead of borrowing an
+   unrelated session's route. Configure a direct MemOS provider if this
+   recovery must run LLM stages. Normal turn, tool-feedback, explicit-tool,
+   and session-close work remains scoped to the owning session. The default
+   lightweight mode does not run the LLM-backed reward/evolution recovery path.

 from "mis-phrased request" from the response alone — that's a
 feature for security; debugging happens via the log SSE.
 
-## S10 — Server close drains but doesn't kill
-
-`server.close()` stops accepting new connections and waits for
-existing ones to complete. Long-lived SSE connections will stall
-shutdown; the bridge sets a 5s deadline above which it force-closes
-the socket. We do NOT call `server.closeAllConnections()` from inside
-the module — that's the caller's choice.
+## S10 — Opted-in SSE shutdown cannot make server close unbounded
+
+`ServerHandle.close()` first calls `server.close()` so no new requests are
+accepted. When the host opts into `closeActiveSseOnShutdown`, it then destroys
+only successful GET responses from the canonical and legacy-prefixed
+events/logs routes; redirects and failed authentication are not treated as
+streams. Socket closure runs each SSE route's cleanup and unsubscribes its core
+listener. The option defaults to false; the DSH adapter enables it because
+Cordis gives the whole plugin tree a short disposal window, while existing
+OpenClaw/Hermes behavior is unchanged.
+
+Ordinary HTTP handlers are not force-closed. They drain naturally before
+`close()` resolves, avoiding a race where memory-core or SQLite shutdown starts
+while an accepted mutation is still running. For an opted-in host, close time
+can therefore be extended by normal request completion, but never by an
+indefinitely open Viewer SSE connection. Without the option, the existing
+all-stream drain behavior remains intact.
