DSH 的消息召回：将对话截回到所选用户消息之前，使该消息退出模型上下文，在记录中隐藏它，并将其原始文本放回输入框。通过内核自身的界面替换机制运行，因此不会从会话日志中删除任何内容。
插件会安装到这里；不确定时保持 web。

Message recall for DeepSeek Harness: cut the conversation back to before a message you already sent.
A sent message cannot be edited or withdrawn. This plugin cuts the model-visible surface back to before a chosen user message, hides that message and everything after it in the transcript, and puts the original text back in the composer so you can correct it and send it again. Files the recalled turns changed are put back byte for byte, and every displaced byte is kept in a quarantine you can look into and clear. A recall that could not cover everything says so instead of claiming a clean revert.
The confirmation dialog before a recall: which files the recall will change, a real before/after diff for each one, and where the bytes that were in the way end up. Nothing is deleted.
| Surface | Where |
|---|---|
| Per-message recall icon | hover a user message in the transcript |
/rewind | bare lists the recallable messages; /rewind <n> recalls one; /rewind plan <n> previews without doing it |
| Composer prefill | the recalled text returns to the input box, once per recall |
| Settings → Recall quarantine | its own page in Settings: every displaced file, grouped by session, discard per row or per session behind a confirm |
The quarantine page registers into settings.section, the settings shell's own additive seat, so it
sits beside the shipped General / Models / Plugins pages. A profile without the settings shell loses
the page and nothing else.

web is the shipped profile name — use whichever profile you run. Every form writes the package
load it.
The official desktop client has no command for this. Its desktop profile is reserved for the
Electron application, and the CLI refuses to touch it (error: profile "desktop" is managed exclusively by the Electron application). Install from inside the app instead:
Settings → Plugins → Add plugin, enter @jochenyang/dsh-rewind-plugin under "Package name or
address", install, and restart the app. That field also takes a Git address, a local directory or a
.tgz, and the page says itself that a new plugin loads at the next start.
load it.
peerDependencies deliberately declares no @deepseek-ai/dsh-* package. The installer compares
every such peer against the running runtime version and refuses the install when it does not match,
which would pin the plugin to one DSH release. This plugin needs nothing installed to run — the
runtime packages below are already present in any DSH profile — so the check is skipped and any
runtime version installs. The tradeoff is deliberate: a DSH release that breaks one of those
interfaces will load the plugin and fail at that call, instead of being refused at install time.
The session log is append-only and stays the source of truth. A recall appends one event carrying
surfaceOp: { op: 'replace', startSeq, endSeq }, so the log keeps every event, and a reader that
ignores surface ops still sees the full transcript.
Files are never unlinked. The bytes in the way move into
$DSH_HOME/storages/dsh-rewind-plugin/quarantine/<session>/<slot>/ — with a manifest.json naming
the original path — before the before-image is written back. A file the recalled range created is
moved there rather than deleted.
A recall has to know what the range started from, so the plugin takes one bounded copy of the
workspace before a turn's first writing tool and stores it content-addressed under
$DSH_HOME/storages/dsh-rewind-plugin/{trees,blobs}. That copy is what makes a file a shell command
rewrote restorable: the write / edit waterfalls still supply the exact before-image for the tools
they see, and where the snapshot covered a path its bytes are the ones that go back.
Resolved from the profile, never bundled:
@deepseek-ai/cordis, @deepseek-ai/dsh-commands, @deepseek-ai/dsh-session,
@deepseek-ai/dsh-session-projection, @deepseek-ai/dsh-llm, @deepseek-ai/dsh-home-paths,
@deepseek-ai/dsh-client-connection, @deepseek-ai/schemastery, zod.
The browser half requires only react, react/jsx-runtime, react-dom/client and
@deepseek-ai/dsh-client-ui-primitives, all supplied by the shell's own module table. It does not
list them in dsh.client.external because the shell already answers them.
$DSH_HOME therefore cannot both write
the same session: the second one's command execution is refused with session/writer-held, and a
recall reports that the request never reached the kernel. Reading a session from a second instance
is fine and different sessions never conflict — close it in the other window, or work in another
session.coverage verdict — full, partial or none — with the reason and the writing
tools involved, so a gap is visible instead of silent.node_modules, .git, …) are outside coverage on purpose,
so a recall that ran npm install does not report the dependency tree. Build output such as dist/
IS walked.size + mtime unchanged counts as unchanged. A writer that restores an old mtime at an unchanged
size is missed — the same bargain every sync tool makes.user/message. The DeepSeek provider's request path drops an empty
user message, so it contributes no model-facing turn there; a provider that does not drop empty
user content would see one extra empty message per recall.npm install
npm run build # lib/index.js + lib/client.js
npm run typecheck
npm test # bundles tests/*.test.ts with esbuild, then node --test
npm run build marks @deepseek-ai/*, @cordisjs/*, react, react-dom and zod external, and
wraps the browser half in the window.__ModuleLoader__.load({ id, factory }) closure the web client
loads. Never bundle an @deepseek-ai/* package: a second copy breaks class identity against the
running host.
lib/ is committed, so dsh plugin add github:JochenYang/dsh-rewind-plugin installs without a
build step — pnpm refuses to run a git dependency's build script unless the installing profile
allowlists it. Run npm run build after changing src/; prepublishOnly does the same before a
registry release.
| Path | What lives there |
|---|---|
src/index.ts | the host half: /rewind, the write recorder, the snapshot/revert path |
src/cut.ts | the recall computation — anchors, the replacement range, the placeholder |
src/projection.ts | the rewindAnchors projection, the client's whole read face |
src/routes.ts, src/quarantine.ts, src/snapshots.ts | the quarantine routes, listing/purge, and the before-images |
src/trees.ts | the workspace snapshot store and its retention rules |
src/recorder.ts | which file change belongs to which turn |
src/wire.ts | the payload shapes and error codes both halves share |
src/client.ts | the client half: icon, picker, prefill, hidden turns, the Settings page |
src/client/ | the components, dictionaries and the injected stylesheet |
cordis.patch.yml | the one insert row that mounts the plugin |
