boxd

Community blueprint — no shipped adapter. TechFabric Harness does not ship or certify an adapter for boxd, and nothing here is covered by the conformance suites. fh add boxd scaffolds a project-owned adapter that you implement and validate yourself with validateSandboxAdapter(). See the target matrix for what is shipped.

Run fh add boxd. The versioned recipe installs the connector packages and creates a managed RemoteSandboxApi adapter plus its contract test. Implement the provider calls for shell exit semantics, binary files, cwd/environment, timeout/abort, lifecycle cleanup, and reconnectable references.

Keep boxd credentials host-side, run validateSandboxAdapter(), and complete a real create/execute/cleanup smoke before production.
