dsh-bundle-manager

dsh-bundle-manager

English | 中文

A runtime mount manager for optional third-party plugin bundles in DeepSeek Harness. Provides the「插件挂载管理」(Plugin Mount Manager) settings section that mounts/unmounts bundle rows in-process through the Loader API — instant effect, no restart, never rewrites the profile manifest, with named presets, a failure ledger and self-healing fallback.

Install

Install from npm with the official CLI (one step: adds the dependency, then reconcile appends the package to dsh.profile.bundles):

dsh plugin --profile <profile-name> add dsh-bundle-manager

npm latest is currently 0.5.3; upgrade later by re-running with @latest (dsh plugin --profile <profile-name> add dsh-bundle-manager@latest).

Key architecture requirement: optional third-party plugins must live in dependencies only (NOT in dsh.profile.bundles), and this plugin is the only framework bundle that mounts them at runtime. The resulting profile layout (what the CLI produces):

{
  "dependencies": { "dsh-bundle-manager": "^0.5.3" },
  "dsh": { "profile": { "bundles": ["dsh-base", "dsh-web-app", "dsh-settings-ui", "dsh-bundle-manager"] } }
}

Local development (optional): npm pack to build the tarball, then dsh plugin --profile <profile-name> add ./dsh-bundle-manager-<ver>.tgz (or a file: dependency), re-packing on every change — see Development.

What you get

• Draft switches + one-shot apply — toggle plugins in a local draft, click Save & Refresh to apply the whole table (host diffs create/remove + persists, then hard-refreshes the page so client halves reconcile)
• Named presets — save the current draft combination as a preset (uncommitted toggles are merged into the snapshot; saving a new preset auto-activates it), switch from the dropdown, delete via multi-select with irreversible confirmation
• Self-healing — bad plugins land in a Failed group (kind + attempts + error) and the rest keep working; 20s mount watchdog; grouped-parallel boot (DSH_PM_BOOT_GROUPS, 1–8)
• Safety — framework whitelist protects core bundles (framework-protected); atomic registry writes with .bak last-known-good and automatic legacy-path migration
• Official coexistence / double-track (v0.5) — reversible switching between the official static layer (dsh.profile.bundles) and the bm runtime layer: import a statically-bundled plugin into bm, export a bm-managed plugin back to the official static layer (or export all as a safety net), with A-level redundancy (atomic manifest write + backup + JSON.parse rollback, one-click batch rollback, dependency-group hints, framework hard-protection). Plus the uninstall half: bm de-registers the registry row first, then guides dsh plugin remove pkg...; a reactive GC clears rows for packages removed externally (bypassing bm).

API (fenced /bundle-manager/api, browser-trust fence)

Method	Body	Returns
list	{}	plugins[] (state/regState/version/managed/waitingFor/kind/attempts) + profile/activePreset/presets/bundles + storage block
apply	{ entries: { pkg: true|false } }	one-shot diff apply + persist (serial queue, 30s cap)
preset/save	{ name, draft? }	save snapshot (draft merged, new name auto-activates)
preset/switch	{ name }	diff switch (keeps shared plugins mounted)
preset/delete	{ names: string[] }	multi-delete (rejects default / active preset)
import-to-bm	{ pkg: string[] }	official → bm (remove from bundles, pre-register, guide restart)
export-to-bundles	{ pkg: string[] }	bm → official static layer (add to bundles, superseded-by-static)
export-all-to-bundles	{}	safety net: write back ALL managed to the official static layer
import/rollback	{ id }	one-click rollback of an import batch (snapshot restore)
uninstall	{ pkg: string[] }	bm de-registry first, then guide dsh plugin remove pkg...

Official coexistence (double-track, v0.5)

Plugins can live in either track; switching is reversible and needs a restart (the compact dsh client has no unload chain, see the manual):

• Official static layer (dsh.profile.bundles) — loaded by dsh at boot, permanent. Plugins here are not bm-toggleable (they appear read-only as superseded-by-static); use 导入到 bm (import-to-bm) to hand one over to runtime management.
• bm runtime layer — mounted/unmounted in-process with zero restart. Use 导出到官方 (export-to-bundles) to permanently coalesce a plugin back to the static layer, or 导出全部到官方 (export-all-to-bundles) as a safety net before removing bm itself.

Because import/export edit the profile manifest, they are the three explicit exceptions to the "never write the manifest" rule, and all run through A-level redundancy: atomic write with .bm.bak backup + JSON.parse rollback, pre-registration with visible failures (imported/rejected), one-click batch rollback, dependency-group hints, and framework hard-protection.

Uninstall half (v0.5): ① bm出库 — clear the registry rows (bm-owned file only, never the manifest); ② guide the official dsh plugin remove pkg... (official CLI passes through pnpm, supports batching, and reconcile automatically pulls packages out of bundles). Clearing first keeps the operation reversible: if the official removal fails, the package degrades to a dormant dependency (installed, idle) — flip it back on in the settings page (registry row rewritten) to restore management. A reactive GC also cleans up rows for packages removed externally (bypassing bm) and records a visible failed entry.

Family single-track note: the other first-party family plugins (mcp / search / proxy / skill / balance …) stay single-track — dependencies-only, mounted at runtime by bm, not participating in import/export (their repos are untouched). Double-track is an optional enhancement for external users: install everything via official dsh plugin add, then import only what you want bm to manage. No family plugin needs double-track adaptation to be managed by bm.

Compatibility

• Verified on dsh 0.1.0-rc.5 (official desktop shell, framework-only bundles).
• rc.6 verified (2026-08-17): rc.5/rc.6 share the same upstream commit (47f9438) — runtime mount/unmount, framework whitelist, failed isolation, presets, registry persistence and the client half all pass with zero code adaptation. Known difference: link: mounts fail ESM resolution on rc.6, use file: tarballs.
• rc.7 (2026-08-19): settings.section (the only kit surface bm uses) is unchanged on rc.7; the kit is pinned to the npm release dsh-settings-ui@0.2.22 (bm does not depend on kit 0.3.0's pluginCard/settingsScope). bm v0.5 coexists with the official static layer (import/export). Full shell verification is performed through the rc7-bm test profile (see the runbook); contract deltas beyond settings.plugin.item list→keyed (which bm does not consume) are tracked by the kit alignment plan.

Development

npm test     # offline regression harness (210 assertions, mock ctx driving the fenced API)
npm run ci   # 5-step gate: syntax + harness + secret scan + sanitization + pack whitelist
