+// makeRBACRules translates Consul intentions into RBAC Policies for Envoy.
+//
+// Consul lets you define up to 9 different kinds of intentions that apply at
+// different levels of precedence (this is limited to 4 if not using Consul
+// Enterprise). Each intention in this flat list (sorted by precedence) can either
+// be an allow rule or a deny rule. Here’s a concrete example of this at work:
+//
+//     intern/trusted-app => billing/payment-svc : ALLOW (prec=9)
+//     intern/*           => billing/payment-svc : DENY  (prec=8)
+//     */*                => billing/payment-svc : ALLOW (prec=7)
+//     ::: ACL default policy :::                : DENY  (prec=N/A)
+//
+// In contrast, Envoy lets you either configure a filter to be based on an
+// allow-list or a deny-list based on the action attribute of the RBAC rules
+// struct.
+//
+// On the surface it would seem that the configuration model of Consul
+// intentions is incompatible with that of Envoy’s RBAC engine. For any given
+// destination service Consul’s model requires evaluating a list of rules and
+// short circuiting later rules once an earlier rule matches. After a rule is
+// found to match then we decide if it is allow/deny. Envoy on the other hand
+// requires the rules to express all conditions to allow access or all conditions
+// to deny access.
+//
+// Despite the surface incompatibility it is possible to marry these two
+// models. For clarity I’ll rewrite the earlier example intentions in an
+// abbreviated form:
+//
+//     A         : ALLOW
+//     B         : DENY
+//     C         : ALLOW
+//     <default> : DENY
+//
+// 1. Given that the overall intention default is set to deny, we start by
+//    choosing to build an allow-list in Envoy (this is also the variant that I find
+//    easier to think about).
+// 2. Next we traverse the list in precedence order (top down) and any DENY
+//    intentions are combined with later intentions using logical operations.
+// 3. Now that all of the intentions result in the same action (allow) we have
+//    successfully removed precedence and we can express this in as a set of Envoy
+//    RBAC policies.
+//
+// After this the earlier A/B/C/default list becomes:
+//
+//     A            : ALLOW
+//     C AND NOT(B) : ALLOW
+//     <default>    : DENY
+//
+// Which really is just an allow-list of [A, C AND NOT(B)]
