## Start and ownership
`start(request)` resolves the child's working directory, spawns the runtime through `DeepSeekHarness`, and completes the `initialize` handshake (with the configured `provider`/`model` route) before it fulfills. Fulfillment therefore means the child runtime is ready and ownership has transferred to the caller. A spawn, handshake, or pre-publication cancellation failure rejects only after the subprocess has been reaped; a working-directory resolution failure rejects before anything is spawned.
`start(request)` resolves the child's working directory, spawns the runtime through `DeepSeekHarness`, and completes the `initialize` handshake (with the configured `provider`/`model` route and optional `maxTokens` output cap) before it fulfills.

The working directory resolves exactly like the ACP backend, through the seam's shared out-of-process helpers ([`dsh-subagent`](../subagent/README.md)): the configured `cwd` override when set (validated once at load), else the delegating parent session's cwd — never the server process's own cwd. The resolved path becomes the child process cwd and the workspace cwd of its SDK session.
