Managing flow context keys

Flow context can be read and updated from an Expression policy through context["flow_plan"].context.

This is useful when you want to influence later stages in the same flow, such as changing a redirect target or passing derived data to another stage.

For redirect_stage_target, use the format ak-flow://{slug} when you want the Redirect stage to redirect to another flow. See redirect_stage_target for the full behavior.

Set a flow-context key

context["flow_plan"].context["redirect_stage_target"] = "ak-flow://redirected-authentication-flow"
return True

Remove a flow-context key

context["flow_plan"].context.pop("redirect_stage_target", None)
return True

Be careful when modifying flow context in widely reused policies, because the change affects the active flow plan, not only the policy itself.
