Live previews allow reads; sandboxes allow confined mutations. Contexts retain exact scope, session identity, target generation and expiry in private local custody. Select one for supported business commands with --emulation; ordinary sign-in and deployment selection remain independent. Usage: bijection emulation [flags] bijection emulation [command] Available Commands: catalog Discover scope resources, permissions, roles, clearances and eligible presets diagnose Inspect declared dependencies and invocation restrictions under this preview end Stop local execution, then end the native session with retryable cleanup custody explain Explain native access under this preview forget Remove local custody after confirmed termination or an expired pending admission list List your native previews, including sessions whose local context was lost resume Recover the original admission or restore an existing session without extending it start Retain an exact admission request, then create its native preview status Inspect native liveness, fixed scope and sandbox cleanup progress Flags: -h, --help help for emulation --help-all Show all commands and options, including administrative controls. --help-json Print command input and output schemas as JSON without executing it. Use "bijection emulation [command] --help" for more information about a command. ``` ## bijection emulation catalog ```text theme={"theme":{"light":"github-light-default","dark":"github-dark-default"}} Discover scope resources, permissions, roles, clearances and eligible presets Usage: bijection emulation catalog [flags] Flags: --deployment string Use emulation on a specific deployment. Accepts: • a deployment name (e.g. joyful-capybara-123) • a deployment reference (e.g. dev/james, staging) • dev (for your personal dev deployment) • prod (for your project’s default production deployment). You can also select deployments in other projects with project-slug:reference. --format string Output format; JSON preserves exact values.
