tcgbp/dock-flash

The dock-base adapter for the DSH Quick Control panel — it mounts the panel into the DSH Workbench through ctx.workbench. The panel itself (its component tree, the quickControl switch registry, the skin system, the zh/en i18n, the alert surfaces, the host routes and the standalone ⚡) is the separate package dsh-flash.

Core + adapter

Package	Role	Depends on dock-base?
dsh-flash v1	The panel core. Owns the React panel, the quickControl registry, the skin system, the alert surfaces, the standalone ⚡ and the whole host half (settings namespace, /plugins/dock-flash/… routes).	No — runs on its own
dock-flash v3 (this package)	The thin adapter. Registers the panel into a dock-base Workbench and claims it from the core. Publishes no service of its own.	Yes — dock-base is a non-optional peer

The two halves meet at exactly one object: the core's dockFlashPanel service. The adapter reads the panel through panel.* on that service and never reaches into the core's internals, so the boundary is a closed set.

What you want	Install	You get
Workbench (dock-base) integration	dock-flash@^3, which pulls dsh-flash in — plus dock-base	Sidebar/floating panel, settings card, activity-bar ⚡, editor view, the dock-flash:openQuickControl command
Only the standalone floating ⚡	dsh-flash alone	A ⚡ trigger in the configured conversation slot → floating panel

This package is not the panel. The switch registry, skins, i18n, alert routes and the standalone trigger all live in dsh-flash — see the core README for all of that. This document covers the adapter and the split only.

Upgrading from dock-flash v2

1. A ^2.x range keeps you on the old single package — nothing breaks by default. The split added a new major (dock-flash@^3) rather than replacing v2. To move, install dock-flash@^3; it depends on dsh-flash, which npm installs for you.
2. One profile edit is required and easy to miss. In the profile's cordis.patch.yml the entry carrying the panel settings is - id: dock-flash with name: dock-flash — a non-insert patch whose name: is an assertion about the target row's current specifier. After the split id: dock-flash resolves to the core row, whose specifier is dsh-flash, so the assertion mismatches, DSH prints patch: name mismatch for "dock-flash" (expected "dsh-flash", got "dock-flash"), skipping, and the whole config: block is dropped — silently reverting panel order, skin and trigger position/size. Fix: change that entry's name: dock-flash to name: dsh-flash and keep id: dock-flash. Do not delete the entry.
3. Do not hand-write the core row into the profile. Installing dock-flash@^3 is the supported path; its bundle patch inserts the core row for you.

What this adapter does

lib/client.js (470 lines) is the whole browser half: the former //#region DockAdapter block promoted to a package. It consumes the core's dockFlashPanel service and makes exactly five ctx.workbench registrations:

Registration	API	Id	Details
Sidebar panel	ctx.workbench.registerPanel()	dock-flash:quick-control	region sideBar, order 50
Plugin entry	ctx.workbench.registerPlugin()	dock-flash	Settings card; visibility toggle + Open
Activity bar item	ctx.workbench.registerActivityBarItem()	dock-flash:quick-control	paneId dock-flash:quick-control
Editor view	ctx.workbench.registerEditorView()	dock-flash:quick-control	draggable to a floating window
Command	ctx.workbench.registerCommand()	dock-flash:openQuickControl	opens the view floating

It publishes nothing — no quickControl, no dockFlashPanel. The panel it renders is wrapped in the core's ErrorBoundary and uses the core's panel.Header and panel.icon; user settings are read through panel.i18n / the panel service only.

The claim handshake

On mount the adapter calls panel.host.claim(), then lease.confirm(). The per-mount disposer calls panel.host.releaseOne() only — never release(). The whole-host panel.host.release() is called only on the dock-hidden path (when wb.getHiddenPluginIds() contains dock-flash), which hands the panel back so the core can put its standalone ⚡ back up.

The rationale matters: an earlier version also called release() in the per-mount disposer, and that broke the two-mount case — dock-base can mount the panel twice at once (the sidebar pane and a floating window). release() is the whole-host release, so the first mount's teardown pulled the panel out from under the second one that still held it. A per-mount disposer releases exactly one claim.

If the workbench service has not arrived yet, the adapter subscribes with ctx.inject(['workbench'], …) and mounts when it does, rather than assuming a load order; "the service is coming" and "dock-base is not installed" stay distinct. The adapter also refuses a dockFlashPanel whose version !== 1, leaving the core's ⚡ in place rather than drawing half a panel.

The host half

src/index.ts (34 lines) is a deliberately empty host plugin:

export const name = 'dock-flash-adapter'
export const inject: string[] = []

export function apply(_ctx: Context): void {
  // Intentionally empty. Everything this package does is in `lib/client.js`.
}

It exports name = 'dock-flash-adapter', not dock-flash — that name belongs to the core's host plugin, which owns the settings namespace. It exists for exactly one reason: a client bundle attaches to a profile row whose specifier is the bare package name, so a package with no host entry point has no row to hang its browser half on.

inject: [] is deliberate. Declaring dockFlashPanel there would make cordis silently skip apply() while the service is absent, so a broken install would look identical to "not installed". Instead apply resolves the service with ctx.inject(['dockFlashPanel'], …) and arms a 2000 ms watchdog that logs this loud error instead of no-opping:

[dock-flash] the core panel service (dockFlashPanel) never arrived — the dsh-flash core is not installed, or its client half did not load. The panel will not be mounted into the workbench. Install or reinstall it with `dsh plugin install dsh-flash`, then reload.

How the two rows are composed

cordis.patch.yml inserts two rows:

- insert:
    - id: dock-flash
      name: dsh-flash          # the CORE
    - id: dock-flash-adapter
      name: dock-flash         # this package

Why the core row is here. A hoisted package is not a composed row. DSH composes the rows a profile names, plus the rows a composed package's own bundle patch inserts; nothing walks a dependency's dsh.bundle.patch merely because the dependency is present. dsh-flash is a real dependencies entry, so it lands on disk — but without the first row an adapter-only install would load no core plugin and publish no dockFlashPanel, and the adapter's watchdog would simply run out.

Why the id stays dock-flash. The entry id is the settings namespace. Consequently the settings namespace, the dock-flash:* switch ids, the dock-flash:… localStorage keys and the /plugins/dock-flash/… host routes all legitimately stay dock-flash. That is not a bug — do not "correct" those strings anywhere. Keeping the id is what makes the split migration-free.

The client module id is dock-flash; the core's is dsh-flash — two client modules cannot share one require key.

Requirements

Requirement	Version / value	Notes
dock-base	>=0.1.2-0 <1.0.0-0 || >=0.2.0-0 <1.0.0-0	peer, non-optional. Provides the ctx.workbench service
@deepseek-ai/cordis	>=4.0.0-rc.1 <5.0.0-0 || >=4.0.1-0 <5.0.0-0	peer (bundled with DSH)
dsh-flash	^1.0.0	regular dependency — the panel core

dsh.client.inject is ["dsh-flash", "dock-base", "@deepseek-ai/dsh-client-runtime", "@deepseek-ai/dsh-api-remotes", "@deepseek-ai/dsh-api-session-controller"], and dsh.bundle.patch points at ./cordis.patch.yml.

Troubleshooting

• A linked core needs its own pnpm install. If you develop against a local dsh-flash checkout (symlinked into the profile), that checkout must have its own dependencies installed. Otherwise the core's host half fails to import with Cannot find package '@deepseek-ai/schemastery', and DSH reports dock-flash (dsh-flash): failed to import.
• The panel never appears and the console shows the watchdog message. The core's client half did not load. Reinstall it: dsh plugin install dsh-flash, then reload.
• Panel order, skin or trigger position reverted after the upgrade. The profile patch's name: assertion mismatched and the config: block was dropped — fix it as described in Upgrading from dock-flash v2. DSH prints patch: name mismatch for "dock-flash" … when this happens.
