dsh-web-app owns --host/--port/--dev/--workspace-root/--trusted-host and its --help in a web-startup row; the rows it configures wait for the webStartup service, and the client-plugin HMR receiver now ships disabled so --dev is a row toggle rather than a runtime insert (the Loader cannot resolve a row inserted from inside a mounting plugin). dsh-headless owns the task positional and rejects a missing task as its own usage error. Its runner ships disabled, not merely waiting: the schema requires the task, and a row's config is validated when its fiber is created, before the startup row can supply one. A composition has exactly one command-line owner, so the patch disables the web startup row and this one provides webStartup too, leaving the web rows on their composed one-shot values. The keyless web scaffold provides the same three values with no arguments, which is what an embedding host with no command line does.
bundle/ — profile plugin bundles
English | 中文
Profile bundles: npm packages whose manifest declares "dsh": { "bundle": { "patch": "./cordis.patch.yml" } }, making them installable patch layers for dsh --profile compositions (profile contract). A bundle's substance is its patch list; some also ship runtime glue plugins their patch mounts.
| Package | Role | ctx key |
|---|---|---|
base/ |
The shared dsh core every profile applies first | — (patch only) |
web-app/ |
Browser surface: web patch layer + runtime glue plugin | mounts rows |
headless/ |
Direct one-shot task mode over base, with no Host or Web layer | mounts headless-runner |
In-box bundles resolve from the dsh installation; out-of-tree bundles install into a profile through dsh plugin --profile <name> add <package>.
