Recall, edit-and-resend and regenerate, plus in-conversation versioning: a timeline of every rewind, artifact rollback (git-first, snapshot fallback), a fork map of explored paths, session lineage, and a real-time watchdog that snapshots the log at the first sign of concurrent writes. Edits auto-stop the running agent (official cancel/whenIdle) so rewinds never corrupt the durable log or break /compact.
Install

dsh plugin --profile web add dsh-retrace
# from GitHub (first run asks for allowBuilds approval — follow the hint, retry)
dsh plugin --profile web add github:yamingmou/dsh-retrace
Any plugin you install runs third-party code with your own permissions — it can read your files, use your credentials, and reach the network, and tool approvals don’t sandbox it. GitHub-sourced plugins also run build scripts at install time — pnpm blocks those until you allow them, so an install can stop with ERR_PNPM_GIT_DEP_PREPARE_NOT_ALLOWED or ERR_PNPM_IGNORED_BUILDS; dsh prints the exact key to add under allowBuilds in your profile’s pnpm-workspace.yaml, and the install works on the next run. Allowing a build is a trust decision: only install sources you trust, and pin a commit (github:owner/repo#sha).
README
🧭 dsh-retrace
Recall · Resend (restart from here) · Regenerate, plus write-safe in-conversation versioning — the Agent business layer (production-grade guarantees) for DeepSeek Harness.
English · 简体中文
Recall / resend / regenerate — the three moves every conversation deserves. But rewinding is not just "delete a message": DeepSeek Harness stores conversations in an append-only event log, so a recall only rewinds the context while changed artifact files stay changed. dsh-retrace versions the conversation and its artifacts together, and keeps every new rewind legal — it cannot dirty the log, and new markers create no token-meter pairing debt (two-segment atomic pairs land by construction).
⚠️ Honest scope (matches the companion contract's own note): sessions that already contain legacy single-segment markers — written by older versions — are known design debt. Before
/compact, run the companioncheckand clean them up (fix --remove-markers); otherwise the host's own pre-compaction self-check blocks compaction. New rewinds do not add to that debt.
🛡️ Write safety · 🔍 Deep offline checks · 🔄 Detect → repair → guard — see below.
⚡ One-minute install
Requires DeepSeek Harness with the
dshCLI. Restart DSH after install (a running app does not hot-reload).
dsh plugin --profile desktop add dsh-retrace # DSH Desktop
# or Web: dsh plugin --profile web add dsh-retrace
# or from an unpacked checkout / ZIP:
# dsh plugin --profile desktop add ~/plugins/dsh-retrace
No command line? Install the community plugin market once, then find dsh-retrace in Settings → Plugin Market and install it with one click:
dsh plugin --profile desktop add dshmarket # one time
After the restart, hover any assistant reply → ↩ / ↻; any user message → ✎. Full steps in 📦 Installation.
🛡️ Production-grade guarantees (all live in 0.4.x)
| Capability | What it means | |
|---|---|---|
| 🛡️ | Write safety | Every rewind passes a three-layer pre-write contract guard; a running agent is stopped automatically (official cancel/whenIdle, with a bounded wait); turn-interval markers are wrapped in a temporary step — new rewinds cannot dirty the log and add no token-meter pairing debt; legacy single-segment markers are known debt (run the companion check + fix --remove-markers before /compact) |
| 🔍 | Deep offline checks | Companion dsh-log-contract ships 30+ contract rules (token-meter pairing / cross-step references / physical order / inbox replay), validated against real corrupted-session fixtures — it finds the class of problem that makes /compact permanently fail |
| 🔄 | Detect → repair → guard | A watchdog snapshots the log at the first sign of concurrent writes; offline fix neutralizes problem markers and clips cross-step references in place; pre-write validation stops bad events before they land |
✨ Features
| Action | Where | What happens |
|---|---|---|
| ↩ Recall | hover any assistant reply, or the row under any user message | Opens a confirmation first (destructive: this message and everything after it leaves the conversation). On confirm, if a turn is still running the plugin pauses it first through the official stop entry and waits (bounded); if the pause fails or times out the recall still continues, with a visible notice. The whole exchange round (the input and the agent's output, tool rows included) is then removed from both the model context and the conversation view; the input text is echoed into the composer so you can re-ask or re-edit immediately. A transient notice marks the rewind and disappears once you keep typing. |
| ✎ Resend (restart from here) | row under any user message | The primary meaning is restart from this message: this round and everything after it is rewound and the new text is re-sent, so the conversation continues on a new timeline branch. If that range is refused by the guard (too large to rewrite in place), the error offers a fallback action — Change this text only (keep what follows). A collapsed "original input" reference sits right under the new message — click to expand, configurable off. |
| ↻ Regenerate | hover any assistant reply | The reply (and everything after it) is rewound and hidden, then the original prompt is re-sent so the agent answers again. |
Undoing a recall
| Action | Scope | What happens |
|---|---|---|
| ↺ Restore display | view only | Puts the rows hidden by that marker back into the conversation view. The log only grows, the model context is unchanged, and the recall trace stays. Available on the marker row. |
| ⏪ True restore | log level | Neutralizes the two marker segments in place (sequence numbers are not renumbered), so the recalled range returns to the model surface and its edit / resend / recall actions work again. Requires an idle session that is not the one you are currently viewing; once it succeeds, switch away and reopen that session (or refresh the page) to see the restored content. Refusals are explained with a next step (session running / held by another process / already re-shadowed by a later marker / host does not provide the capability). |
Checkpoints & rollback (live in 0.4.x) — every rewind is also recorded as a checkpoint:
| What | ||
|---|---|---|
| 🕘 | Checkpoints | a Checkpoints tab in the conversation view: every change (type, time, message count, file-change badges), pushed live via session/projection (no polling), windowed for long histories; nested history is browsable outline-style |
| ↩️ | Artifact rollback | context-only / artifacts-only / both with dry-run preview; git-first + content-addressed snapshot fallback; a rollback is itself a new checkpoint (restore). Preview refuses while the agent is running (so "preview says yes, confirm says no" cannot happen), and preview/rollback failures are shown in the UI instead of failing silently |
| 🧭 | Jump-to-conversation | one click from a checkpoint to that point in the conversation (auto-loads history, anchor highlight); when the point is out of the auto-load budget the reason is reported instead of nothing happening |
| 🧹 | Bounded storage | snapshots keep the most recent N checkpoints (default 50); throttled background sweep prunes truncated ones |
Rollback on a damaged log is not silent: the host's strict replay is the authority, but a single malformed event (for example a
sourceEventSeqsrow written by a third party with range encoding) can poison the whole replay. In that case the rollback degrades to a mirror replay, logs both the degradation and the original error, and flags the result asdegradedon the wire; if even the mirror cannot run you get a structuredreplay-failederror, not a genericinternal.
Why it's different (the interaction layer — the guarantees above are the storage layer):
- 🎯 Whole-round recall — removes the input and its output (tool rows included), not just a single bubble.
- 🖥️ Web + Desktop — one plugin, both DeepSeek Harness surfaces.
- 🧠 View ⇄ context in sync — the conversation view always reflects exactly what the agent sees.
- ⚡ Try in 30 seconds — the dynamic form installs in your current session with no rebuild.
📦 Installation
1. Profile bundle (recommended)
The package declares a dsh.bundle manifest, so it installs through the official
plugin path into any profile:
dsh plugin --profile <name> add dsh-retrace
⚠️ Restart required. The install writes the new files and re-renders the profile composition, but a running app does not hot-reload bundles — quit and reopen DSH Desktop (or restart the
dshprocess for a standalone Web deployment) to load the plugin. To uninstall:dsh plugin --profile <name> remove dsh-retrace(then restart again).
2. Manual install (no dsh CLI)
The same result with plain file edits and pnpm — exactly the steps
dsh plugin add performs for you:
Downloaded this repo as a ZIP? Unpack it somewhere stable (e.g.
~/plugins/dsh-retrace), then eitherdsh plugin --profile desktop add ~/plugins/dsh-retrace, or follow the steps below with the dependency line pointing at the folder:"dsh-retrace": "file:~/plugins/dsh-retrace".
Open the profile manifest (defaults:
<plugin data home>/profiles/desktopon DSH Desktop,<plugin data home>/profiles/webfor standalone Web — where<plugin data home>is$DSH_HOMEwhen set, otherwise the active session base, e.g. a newerDSH_HOMEdirectory;~/.dsh/profilesis only the pre-migration fallback) and add both the dependency and the bundle-layer entry:{ "dependencies": { "dsh-retrace": "^0.4.130" }, "dsh": { "profile": { "bundles": [ "@deepseek-ai/dsh-base", "@deepseek-ai/dsh-web-app", "dsh-retrace" ] } } }(Keep whatever entries your profile already has; only add the two
dsh-retracelines.)Install inside the profile directory:
cd "$DSH_HOME/profiles/<name>" && pnpm install # or the active base you useRestart DSH Desktop / the
dshprocess (see above).
For local development, point the dependency at a checkout instead of the
registry: "dsh-retrace": "file:/path/to/dsh-retrace" — or let
dsh do it: dsh plugin --profile <name> add /path/to/dsh-retrace.
For the latest commit without a release, add a git dependency using the repository
URL from this package's repository field (pnpm syntax
"dsh-retrace": "github:<owner>/dsh-retrace") in the same dependencies block,
then pnpm install.
3. npm package + composition (classic)
npm i dsh-retrace
Add the package to the harness composition (cordis.yml of the app/deployment you use):
- name: 'dsh-retrace'
The client half is picked up automatically from the package's dsh.client metadata and
bundled into the Web client (a client-module rebuild happens automatically when the
composition changes). The Host half registers the same-origin HTTP route
/api/plugins/retrace/* for the browser UI.
4. Dynamic plugin (current session — no install, no rebuild)
Use the dynamic entries shipped in the package. In the session where you want the feature:
- Open the plugin editor and define a new plugin from
lib/dynamic-host.js(Host half) andlib/dynamic-client.js(Client half). - Approve and run the Client half.
- Done — hover any assistant reply, or any user message, and use ↩ / ✎ / ↻.
The dynamic host registers the same operations behind the package-private
harness.handle RPC (retrace.recall / retrace.editAndResend /
retrace.regenerate).
5. Requirements
- DeepSeek Harness providing the peer packages listed in
package.json(@deepseek-ai/dsh-session,@deepseek-ai/dsh-client-*,cordis,react— the current build targets the0.1.7-rc.2generation). dsh-log-contract >= 0.3.12(installed automatically as a dependency).- The plugin declares the host capabilities it needs via
inject(sessions,agents,webServer,fs,subprocess,sandboxPolicy,jobs). A missing capability degrades the corresponding feature (for example, nosubprocess⇒ rollback uses the built-in snapshots only); it does not block boot.
🔒 Close guard (don't lose work by accident)
Before you exit or reload, know what is still running:
| What | ||
|---|---|---|
| 🛡️ | Running-work detection | every session is scanned for live work: agent running, queued inbox items, background jobs, unclosed turns |
| 📋 | Running banner | sessions with live work show a persistent in-page banner (short session code + reasons), so you can see it before quitting |
| ⚠️ | Exit prompt | on plugin dispose (app exit / reload) a Chinese notice lists each running session and why it is considered busy — it only warns, it never cancels your running agent |
| 🔒 | Page-close interception | The desktop never arms the host's native confirm dialog; it uses a page-drawn confirm gate instead: it draws the box and verifies visibility synchronously before blocking (preventDefault); if it cannot draw, is not visible, or the page is hidden ⇒ lets the close through immediately; the dialog waits for your choice (Esc = cancel); a Web-Worker watchdog (immune to background throttling) is only the last resort. Turning off "Exit confirmation (close guard)" recovers immediately (no restart) |
| 🔎 | Query surface | retrace.runningState (host RPC) + GET|POST /api/plugins/retrace/runningState (HTTP) — same shape on both transports; the all-sessions shape also carries the host-reported page surface (surface / quitVeto) |
How the close confirm behaves (user-visible): whether the host pops its own native quit confirmation is decided jointly by the host and the page. On a desktop shell the plugin does not use the host's native dialog — it draws its own in-page confirmation (Esc cancels). If the page cannot draw that box, the box is not visible, or the page itself is hidden, the close is let through immediately. Turning off "Exit confirmation (close guard)" reverts to the host's default behaviour (no restart needed).
Known limitation (stated plainly): some desktop shells route quit around the page entirely (e.g. the tray item destroys the window directly, or the X button merely hides the window) ⇒ on those shells a plugin cannot show a confirm dialog at quit time; it needs a shell seam (a
will-prevent-unloadhandler, or a pre-quit prompt hook). If the app cannot quit, turning off "Exit confirmation (close guard)" recovers immediately (no restart).
Session badge & display name (planned / off by default)
Badges are for human collaboration; identity is still decided by the session id.
The transports (sessionBadge / setBadgeTitle / initBadgeTitles / badgeMap,
on both HTTP and harness), the resolver and the write guards are in place, but
the automatic startup path that writes titles is off by default (the client
gate is globalThis.__DSH_RETRACE_BADGE_BOOTSTRAP = true):
- A session title renders as
[badge] original title— the stable identifier is derived deterministically from the session id, so a title change never changes it. - Sessions with no
session/titleevent are left blank on purpose (the title shows just[badge]) — no project-name fallback, no fabricated name. - If the resolver is unavailable it falls back to the raw session id as a placeholder.
- The sidebar row, the running banner and the checkpoint view share one source: the same badge
map the host hands down (host op
badgeMap).
Planned (not shipped): the agent business-layer plan (runtime guard, interruption governance, ecosystem-facing interfaces) is a plan, not a shipped capability.
⚙️ Settings → General
| Setting | Default | Description |
|---|---|---|
| Show the original input after editing | on | A collapsed "original input" reference under the re-sent message showing the most recent replaced text (reference only — never sent to the model). |
| Checkpoints & artifact snapshots | on | On: every recall/edit records a checkpoint (messages and touched files) powering the checkpoint list and artifact rollback. Off: only rewinds context — no checkpoint records, no artifact tracking (lightest). |
| Summarize old content with AI | off | On: each recall/edit makes one small model call to summarize the discarded old content. Requires the host llm service (the official @deepseek-ai/dsh-llm); absent ⇒ it degrades to verbatim excerpts only. Off: zero LLM calls; the verbatim excerpt (zero token cost) is always recorded. At most one small call per operation (input text capped at 500 characters, ≤200 output tokens, 5 s timeout); model and credentials follow the session's own default selection, and the plugin adds no configuration surface of its own. |
| Git integration | on | On: use git to record and roll back when the workspace is a repository (never auto-commits, never touches your branches); non-repo workspaces can enable git from the checkpoint view. Off: built-in snapshots under the plugin data home only — the plugin never touches the workspace git state; features are equivalent. |
| Checkpoint retention limit | 50 | File snapshots are kept for the most recent N checkpoints; older ones are pruned automatically (checkpoint records and the audit trail are always kept). |
| Exit confirmation (close guard) | off | On: confirm before the page closes when sessions have running or unfinished work (the plugin draws its own dialog; Esc cancels). Off by default because the gate can also intercept an in-app reload — see 🔒 Close guard for the desktop details and the self-recovery note. |
The two toggles "hide shadowed messages per marker" and "start a fresh conversation after editing" no longer exist: recall/resend/regenerate always hide what they replaced (a single marker that would hide more than 40% of the conversation degrades to notice-only, so history never silently vanishes), and resend always uses the "restart from here" semantics with the fallback action described above.
🧠 How it works
durable transcript (append-only) model context & view
┌─────────────────────────────────┐ ┌────────────────────┐
│ … target message │ │ … target message │
│ ↓ shadow span │ │ ↓ rewind │
│ [target … last surface node] │ ──▶│ (empty replace │
│ ↳ one replacement │ │ = context cut) │
│ assistant/message (empty)│ └────────────────────┘
│ ↳ optional original-input │ agent.followup(new prompt)
└─────────────────────────────────┘ → next turn rebuilds request
- Host core (
lib/host-core.js, zero runtime imports) locates the target message in the session's live surface, computes the shadow span[message … last surface node], and appends one replacementassistant/messagewith an empty body — a valid surface node that derives to no model message, so the LLM context simply rewinds. - Resend / regenerate additionally call
agent.followup(...)with the (new) prompt text; the agent's next turn builds its request from the rewoundsession.deriveMessages(). - Client (
lib/client.js) registers:- a
user-actionsconversation node under every user message (a resend/recall row with an inline editor); recall echoes the text into the composer, - the
recall-markernode renderer: a notice row that injects CSS hiding every shadowed message row from the flow (view and model context stay in sync), plus the optional original-input comparison block, the Restore display button and the True restore action, - the
retraceentry in theconversation.chat.assistant-actionsstrip (recall / regenerate), - the Checkpoints view and the preference toggles under Settings → General.
- a
Two different layers are at play: the durable transcript (append-only; old events are never rewritten or deleted) and the model-visible surface (rewound by an appended replacement event). So the old events stay in the log as an audit trail — but they are synchronized out of both the model context and the visible conversation, and the view always reflects what the agent actually sees. Persistence, projections and the transcript remain consistent because the plugin only appends valid, typed session events. (True restore is the one operation that does edit the log, and it does so in place, without renumbering sequences.)
🔺 Compatibility & upgrade notes
dsh-retrace is a bundle plugin: it plugs into whatever host surface it is
installed into. A host release that removes a package or a client service can
therefore break an older plugin build even though nothing in that build changed —
the symptom is usually a failed boot, not a wrong-looking feature.
This section exists so you can tell host-side breakage from plugin-side bugs. Read it before filing an issue.
Host-side breaking changes this plugin adapts to — not caused by this plugin
@deepseek-ai/dsh-sessionremoved theSession.eventsmember (in0.1.5-rc.1). The supported readers aresnapshotEvents(fromSeq, toSeqExclusive)(frozen, sequence-indexed),eventAt(seq),ownEvents()andisOwnSeq(seq). Before the fix, recall and edit did nothing and surfacedTypeError: Cannot read properties of undefined (reading 'length'). The plugin now reaches the log through a compatibility accessor that prefers the new API and falls back to the old array, so both host generations work.@deepseek-ai/dsh-sessiondroppeddecodeStorageRecordfrom its public export surface (in0.1.5-rc.1; the function still exists internally but is no longer exported from the package root and is unreachable via the exports map).dsh-retraceitself never imported it, but its dependencydsh-log-contractdid. With no such export the loader aborts withplugin tree failed to load … does not provide an export named 'decodeStorageRecord'and the whole plugin tree fails to load — not just this plugin, so the app does not start. → Dependency note: needsdsh-log-contract >= 0.3.12.- A client service disappeared:
conversationEvents— it used to be provided by the legacy client runtime@deepseek-ai/dsh-client-runtime, which has been removed. A plugin whose client half still declares that service inexport const injectnever becomes ready: its fiber stays pending, which the host reports asrenderer boot failed (plugins: …): The client Loader did not provide an error message.— no error text at all, the window does not finish starting, and the only way in is to disable the plugin. The plugin drops the service frominjectand resolves it defensively inapply(uiConversation, falling back to the legacy name).Note: declaring a package that no longer exists in
dsh.client.injectis not what breaks the boot — the client loader skips unknown entries silently. The breakage comes from the service name the plugin waits for. - The client-side session store has no
keys()(ctx.sessions). A plugin that enumerates sessions withkeys()silently sees zero of them: no crash, no error, just safety warnings that never fire. The plugin prefers the officiallist()and falls back tokeys(); it deliberately does not fall back to enumerating service fields, because guessing produces a silent empty result as well.
All four items are host-side removals, documented here on purpose: if you hit one of these symptoms right after a host upgrade, the first question is "does this plugin build predate the removal?", not "what did the plugin break?".
Plugin-side fixes (0.4.26 – 0.4.28)
- Data home and session base are now one source. The plugin previously resolved its
own data directory through the host's home resolver (
$DSH_HOME→~/.dsh), which does not know about a migrated base. With$DSH_HOMEunset, sessions were read from one base while snapshots and the artifact store were written to another. Snapshots, version stores andverify-installnow follow the active session base. When$DSH_HOMEis set, behaviour is unchanged. - No user-visible string hard-codes
~/.dshany more (the settings hint used to say snapshots live under~/.dsh). - The edit / recall affordances never appeared at all. The client half read chat
nodes from
snapshot.chat.nodes, a path this host build does not have — nodes live in theuseChatstore (snapshot.nodes). Every message-level component threw while rendering and was swallowed by the error boundary, so the buttons were missing, while the settings entry (which reads no nodes) rendered fine. - "Jump to message" in the checkpoint view did nothing. It resolved the target
anchor through
store.getSnapshot()?.chat?.nodes, which is permanentlyundefinedhere. It now resolves through theuseChatsnapshot injected by the view and pages with the officialstore.loadThrough(seq); when the jump cannot complete it reports a diagnosable reason (renderer warning + host-log line) instead of failing silently. - Assigning a lineage ID could overwrite your session title. Title tagging now goes
through the host route only (
setBadgeTitle), which reads the current title from the session log. Manual renames are unaffected. - Host-side operation failures are logged again (code + message + stack). They used to return the message to the UI without a log line, which made this class of bug hard to diagnose from outside.
- The checkpoint view now explains itself. It used to show a title plus a row of actions with no sentence anywhere saying what a "checkpoint" is, and rows printed raw node types. It now carries an always-visible concept sentence, a type legend, and a plain-language "why" line on every row.
- Client hide-lookup no longer rescans per row.
useSeqHiddenre-scanned the node map for every row (measured 346 ms at 2000 rows / 20 markers, 1568 ms at 3000/30). It now reuses one per-snapshot hide plan: 8.3 ms and 18.3 ms respectively, with the predicate verified equivalent against the old one.
Upgrading
dsh plugin --profile desktop add dsh-retrace@0.4.130
# then restart DSH — plugins are not hot-reloaded
0.4.27 and 0.4.31 were withdrawn (briefly published, then recalled and marked
deprecated on npm). Their replacements carry every fix they had.
No data migration is required. The session format is unchanged (v3), no session is re-written, and nothing has to be re-indexed: upgrade, restart, and the symptoms above are gone. If you are on a host that still provides the old members, the compatibility accessors keep those paths working — this build does not drop older hosts.
If the app fails to boot after an upgrade, a single failing plugin can take the whole tree down, so recover first and diagnose second:
- remove
dsh-retracefrom the profile'sdsh.profile.bundlesand itsdependenciesentry, restart, and confirm you can get back in; - read the host log —
macOS:
~/Library/Application Support/DSH Desktop/logs/host/dsh-<date>.error.log; plugin tree failed to loadis the host half;renderer boot failedis the client half. Both name the offending plugin/package — start there.
Pinning
Pin an exact plugin version (dsh-retrace@0.4.130) and let dsh-log-contract resolve to
>=0.3.12. Do not rely on ^0.4 across a host upgrade: compatibility here is decided by
the host surface, not by semver alone.
⚠️ Requirements & limitations
- Only user messages can be re-sent from; recall works on user and assistant messages. Tool results are shadowed along with the recalled range but are not themselves recall targets.
- A recall that targets a running turn pauses it first (official stop entry, bounded wait). If the pause fails or times out, the recall continues and a notice tells you so. True restore and rollback preview require an idle session; they are rejected otherwise.
- Recall/resend operate on the active model surface: a message that was
already compacted away or previously recalled is rejected
(
target-shadowed), and a message whose write has not flushed yet is reported asmessage-pending("still being generated") rather than being misreported as gone. - Regenerate re-sends only the text of the original prompt; prompts that carried images fall back to the text-only content.
- True restore edits the session log in place (it neutralizes the two marker segments; sequence numbers stay as they are). It refuses to run while the session is the one you are viewing, while it is running, or while another process holds the file, and you must reopen the session (or refresh) to see the result.
🗺️ Roadmap
What's in today (0.4.x):
- Recall / resend / regenerate, each written through a three-layer
pre-write contract guard and a safe-edit path (auto-stop the agent, temp-step
markers) — new rewinds do not corrupt the log and add no
/compactdebt; legacy single-segment markers remain known debt (see the honest note above). - Undo: Restore display (view) and True restore (log level, in place).
- In-session checkpoint timeline + artifact rollback (git-first, snapshot fallback, dry-run preview, jump-to-conversation).
- Close guard (running-work banner, exit notice, page-drawn confirm gate).
- Real-time watchdog — snapshots the log at the first sign of concurrent writes.
- Companion
dsh-log-contract: 30+ offline contract rules + in-place repair (fix --neutralize/--clip-crossstep) for sessions that would fail/compact. - Read-only host surfaces for integration:
retrace/versionsandretrace/forkmapprojections,GET /api/plugins/retrace/{versions,forkmap,lineage,event,surface,doctor,snapshot},POST /api/plugins/retrace/{rollback/preview,rollback,git/init}, plus the badge ops (sessionBadge/setBadgeTitle/initBadgeTitles/badgeMap) and theretraceCLI (see below).
What's next — the agent business-layer plan (runtime guard, interruption governance, ecosystem-facing interfaces) is not published yet: it is a plan, not a shipped capability. This README describes the development line (main), which may run ahead of the latest npm release.

🧭 Session archaeology (retrace CLI)
Every tool call's full input/output is persisted in the session log — a data and

retrace query <session> --cmd "seed-scale" # search outputs by command regex
retrace extract <session> --pattern "seed-scale" --out ./found # export outputs
retrace file-history <session> <path> # write/edit history of a file
retrace file-diff <session> <path> 0 5 # line diff between two versions
retrace lineage <session> # parent-chain lineage
<session> is a full log path or a sessionId (auto-looked-up under the active
session base — $DSH_HOME/sessions, else a newer base, else ~/.dsh/sessions).
All read-only.
Session lineage: GET /api/plugins/retrace/lineage?sessionId= walks the
current session's parentSession chain (read-only, with cycle protection) — the
same semantics as the CLI retrace lineage — so "which session did this one
continue/fork from" is available to any client, and serves as the fork-topology
metadata source.
