+# Corks
+
+Corks are authorization tokens which are based off Google's [Macaroons](https://research.google/pubs/macaroons-cookies-with-contextual-caveats-for-decentralized-authorization-in-the-cloud/) paper. They are bearer tokens which identify the entity possessing them, while providing a mechanism for embedding further restrictions via [Cedar](https://www.cedarpolicy.com/en) policy caveats.
+
+## Development
+
+Corks use Protobuf for serialization and deserialization of bearers and caveats. The proto definitions are located in the [proto](./proto) directory and the [Buf](https://buf.build) toolchain is used to generate Dart code from the Protobuf files.
+
+To generate the Dart code, install Buf then run the following command from the `proto/` directory:
+
+```sh
+$ buf generate
+```

+///  `Any` contains an arbitrary serialized protocol buffer message along with a
+///  URL that describes the type of the serialized message.
+///
+///  Protobuf library provides support to pack/unpack Any values in the form
+///  of utility functions or additional generated methods of the Any type.
+///
+///  Example 1: Pack and unpack a message in C++.
+///
+///      Foo foo = ...;
+///      Any any;
+///      any.PackFrom(foo);
+///      ...
+///      if (any.UnpackTo(&foo)) {
+///        ...
+///      }
+///
+///  Example 2: Pack and unpack a message in Java.
+///
+///      Foo foo = ...;
+///      Any any = Any.pack(foo);
+///      ...
+///      if (any.is(Foo.class)) {
+///        foo = any.unpack(Foo.class);
+///      }
+///      // or ...
+///      if (any.isSameTypeAs(Foo.getDefaultInstance())) {
+///        foo = any.unpack(Foo.getDefaultInstance());
+///      }
+///
+///   Example 3: Pack and unpack a message in Python.
+///
+///      foo = Foo(...)
+///      any = Any()
+///      any.Pack(foo)
+///      ...
+///      if any.Is(Foo.DESCRIPTOR):
+///        any.Unpack(foo)
+///        ...
+///
+///   Example 4: Pack and unpack a message in Go
+///
+///       foo := &pb.Foo{...}
+///       any, err := anypb.New(foo)
+///       if err != nil {

+///       foo := &pb.Foo{}
+///       if err := any.UnmarshalTo(foo); err != nil {
+///         ...
+///       }
+///
+///  The pack methods provided by protobuf library will by default use
+///  'type.googleapis.com/full.type.name' as the type URL and the unpack
+///  methods only use the fully qualified type name after the last '/'
+///  in the type URL, for example "foo.bar.com/x/y.z" will yield type
+///  name "y.z".
+///
+///  JSON
+///  ====
+///  The JSON representation of an `Any` value uses the regular
+///  representation of the deserialized, embedded message, with an
+///  additional field `@type` which contains the type URL. Example:
+///
+///      package google.profile;
+///      message Person {
+///        string first_name = 1;
+///        string last_name = 2;
+///      }
+///
+///      {
+///        "@type": "type.googleapis.com/google.profile.Person",
+///        "firstName": <string>,
+///        "lastName": <string>
+///      }
+///
+///  If the embedded message type is well-known and has a custom JSON
+///  representation, that representation will be embedded adding a field
+///  `value` which holds the custom JSON in addition to the `@type`
+///  field. Example (for message [google.protobuf.Duration][]):
+///
+///      {
+///        "@type": "type.googleapis.com/google.protobuf.Duration",
+///        "value": "1.212s"
+///      }

+  ///    [g,h)  [ 4, 0, 2, 0, 3 ]  The number (1).

+  ///  Notes:
+  ///  - A location may refer to a repeated field itself (i.e. not to any
+  ///    particular index within it).  This is used whenever a set of elements are
+  ///    logically enclosed in a single code segment.  For example, an entire
+  ///    extend block (possibly containing multiple extension definitions) will
+  ///    have an outer location whose path refers to the "extensions" repeated
+  ///    field without an index.
+  ///  - Multiple locations may have the same path.  This happens when a single
+  ///    logical declaration is spread out across multiple places.  The most
+  ///    obvious example is the "extend" block again -- there may be multiple
+  ///    extend blocks in the same scope, each of which will have the same path.
+  ///  - A location's span is not always a subset of its parent's span.  For
+  ///    example, the "extendee" of an extension declaration appears at the
+  ///    beginning of the "extend" block and is shared by all extensions within
+  ///    the block.
+  ///  - Just because a location's span is a subset of some other location's span
+  ///    does not mean that it is a descendant.  For example, a "group" defines
+  ///    both a type and a field in a single declaration.  Thus, the locations
+  ///    corresponding to the type and field and their components will overlap.
+  ///  - Code which tries to interpret locations should probably be designed to
+  ///    ignore those that it doesn't understand, as more types of locations could

+///  A Duration represents a signed, fixed-length span of time represented
+///  as a count of seconds and fractions of seconds at nanosecond
+///  resolution. It is independent of any calendar and concepts like "day"
+///  or "month". It is related to Timestamp in that the difference between
+///  two Timestamp values is a Duration and it can be added or subtracted
+///  from a Timestamp. Range is approximately +-10,000 years.
+///
+///  # Examples
+///
+///  Example 1: Compute Duration from two Timestamps in pseudo code.
+///
+///      Timestamp start = ...;
+///      Timestamp end = ...;
+///      Duration duration = ...;
+///
+///      duration.seconds = end.seconds - start.seconds;
+///      duration.nanos = end.nanos - start.nanos;
+///
+///      if (duration.seconds < 0 && duration.nanos > 0) {
+///        duration.seconds += 1;
+///        duration.nanos -= 1000000000;
+///      } else if (duration.seconds > 0 && duration.nanos < 0) {
+///        duration.seconds -= 1;
+///        duration.nanos += 1000000000;
+///      }
+///
+///  Example 2: Compute Timestamp from Timestamp + Duration in pseudo code.
+///
+///      Timestamp start = ...;
+///      Duration duration = ...;
+///      Timestamp end = ...;
+///
+///      end.seconds = start.seconds + duration.seconds;
+///      end.nanos = start.nanos + duration.nanos;
+///
+///      if (end.nanos < 0) {
+///        end.seconds -= 1;
+///        end.nanos += 1000000000;
+///      } else if (end.nanos >= 1000000000) {
+///        end.seconds += 1;
+///        end.nanos -= 1000000000;
+///      }
+///
+///  Example 3: Compute Duration from datetime.timedelta in Python.
+///
+///      td = datetime.timedelta(days=3, minutes=10)
+///      duration = Duration()
+///      duration.FromTimedelta(td)
+///
+///  # JSON Mapping
+///
+///  In JSON format, the Duration type is encoded as a string rather than an
+///  object, where the string ends in the suffix "s" (indicating seconds) and
+///  is preceded by the number of seconds, with nanoseconds expressed as
+///  fractional seconds. For example, 3 seconds with 0 nanoseconds should be
+///  encoded in JSON format as "3s", while 3 seconds and 1 nanosecond should
+///  be expressed in JSON format as "3.000000001s", and 3 seconds and 1
+///  microsecond should be expressed in JSON format as "3.000001s".

+///  A Timestamp represents a point in time independent of any time zone or local
+///  calendar, encoded as a count of seconds and fractions of seconds at
+///  nanosecond resolution. The count is relative to an epoch at UTC midnight on
+///  January 1, 1970, in the proleptic Gregorian calendar which extends the
+///  Gregorian calendar backwards to year one.
+///
+///  All minutes are 60 seconds long. Leap seconds are "smeared" so that no leap
+///  second table is needed for interpretation, using a [24-hour linear
+///  smear](https://developers.google.com/time/smear).
+///
+///  The range is from 0001-01-01T00:00:00Z to 9999-12-31T23:59:59.999999999Z. By
+///  restricting to that range, we ensure that we can convert to and from [RFC
+///  3339](https://www.ietf.org/rfc/rfc3339.txt) date strings.
+///
+///  # Examples
+///
+///  Example 1: Compute Timestamp from POSIX `time()`.
+///
+///      Timestamp timestamp;
+///      timestamp.set_seconds(time(NULL));
+///      timestamp.set_nanos(0);
+///
+///  Example 2: Compute Timestamp from POSIX `gettimeofday()`.
+///
+///      struct timeval tv;
+///      gettimeofday(&tv, NULL);
+///
+///      Timestamp timestamp;
+///      timestamp.set_seconds(tv.tv_sec);
+///      timestamp.set_nanos(tv.tv_usec * 1000);
+///
+///  Example 3: Compute Timestamp from Win32 `GetSystemTimeAsFileTime()`.
+///
+///      FILETIME ft;
+///      GetSystemTimeAsFileTime(&ft);
+///      UINT64 ticks = (((UINT64)ft.dwHighDateTime) << 32) | ft.dwLowDateTime;
+///
+///      // A Windows tick is 100 nanoseconds. Windows epoch 1601-01-01T00:00:00Z
+///      // is 11644473600 seconds before Unix epoch 1970-01-01T00:00:00Z.
+///      Timestamp timestamp;
+///      timestamp.set_seconds((INT64) ((ticks / 10000000) - 11644473600LL));
+///      timestamp.set_nanos((INT32) ((ticks % 10000000) * 100));
+///
+///  Example 4: Compute Timestamp from Java `System.currentTimeMillis()`.
+///
+///      long millis = System.currentTimeMillis();
+///
+///      Timestamp timestamp = Timestamp.newBuilder().setSeconds(millis / 1000)
+///          .setNanos((int) ((millis % 1000) * 1000000)).build();
+///
+///  Example 5: Compute Timestamp from Java `Instant.now()`.
+///
+///      Instant now = Instant.now();
+///
+///      Timestamp timestamp =
+///          Timestamp.newBuilder().setSeconds(now.getEpochSecond())
+///              .setNanos(now.getNano()).build();
+///
+///  Example 6: Compute Timestamp from current time in Python.
+///
+///      timestamp = Timestamp()
+///      timestamp.GetCurrentTime()
+///
+///  # JSON Mapping
+///
+///  In JSON format, the Timestamp type is encoded as a string in the
+///  [RFC 3339](https://www.ietf.org/rfc/rfc3339.txt) format. That is, the
+///  format is "{year}-{month}-{day}T{hour}:{min}:{sec}[.{frac_sec}]Z"
+///  where {year} is always expressed using four digits while {month}, {day},
+///  {hour}, {min}, and {sec} are zero-padded to two digits each. The fractional
+///  seconds, which can go up to 9 digits (i.e. up to 1 nanosecond resolution),
+///  are optional. The "Z" suffix indicates the timezone ("UTC"); the timezone
+///  is required. A proto3 JSON serializer should always use UTC (as indicated by
+///  "Z") when printing the Timestamp type and a proto3 JSON parser should be
+///  able to accept both UTC and other timezones (as indicated by an offset).
+///
+///  For example, "2017-01-15T01:30:15.01Z" encodes 15.01 seconds past
+///  01:30 UTC on January 15, 2017.
+///
+///  In JavaScript, one can convert a Date object to this format using the
+///  standard
+///  [toISOString()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString)
+///  method. In Python, a standard `datetime.datetime` object can be converted
+///  to this format using
+///  [`strftime`](https://docs.python.org/2/library/time.html#time.strftime) with
+///  the time format spec '%Y-%m-%dT%H:%M:%S.%fZ'. Likewise, in Java, one can use
+///  the Joda Time's [`ISODateTimeFormat.dateTime()`](
+///  http://joda-time.sourceforge.net/apidocs/org/joda/time/format/ISODateTimeFormat.html#dateTime()
+///  ) to obtain a formatter capable of generating timestamps in this format.

+// `Any` contains an arbitrary serialized protocol buffer message along with a
+// URL that describes the type of the serialized message.
+//
+// Protobuf library provides support to pack/unpack Any values in the form
+// of utility functions or additional generated methods of the Any type.
+//
+// Example 1: Pack and unpack a message in C++.
+//
+//     Foo foo = ...;
+//     Any any;
+//     any.PackFrom(foo);
+//     ...
+//     if (any.UnpackTo(&foo)) {

+//     Foo foo = ...;
+//     Any any = Any.pack(foo);
+//     ...
+//     if (any.is(Foo.class)) {
+//       foo = any.unpack(Foo.class);
+//     }
+//     // or ...
+//     if (any.isSameTypeAs(Foo.getDefaultInstance())) {
+//       foo = any.unpack(Foo.getDefaultInstance());
+//     }
+//
+//  Example 3: Pack and unpack a message in Python.
+//
+//     foo = Foo(...)
+//     any = Any()
+//     any.Pack(foo)
+//     ...
+//     if any.Is(Foo.DESCRIPTOR):
+//       any.Unpack(foo)
+//       ...
+//
+//  Example 4: Pack and unpack a message in Go
+//
+//      foo := &pb.Foo{...}
+//      any, err := anypb.New(foo)
+//      if err != nil {
+//        ...
+//      }

+//      foo := &pb.Foo{}
+//      if err := any.UnmarshalTo(foo); err != nil {
+//        ...
+//      }
+//
+// The pack methods provided by protobuf library will by default use
+// 'type.googleapis.com/full.type.name' as the type URL and the unpack
+// methods only use the fully qualified type name after the last '/'
+// in the type URL, for example "foo.bar.com/x/y.z" will yield type
+// name "y.z".
+//
+// JSON
+// ====
+// The JSON representation of an `Any` value uses the regular
+// representation of the deserialized, embedded message, with an
+// additional field `@type` which contains the type URL. Example:
+//
+//     package google.profile;
+//     message Person {
+//       string first_name = 1;
+//       string last_name = 2;
+//     }
+//
+//     {
+//       "@type": "type.googleapis.com/google.profile.Person",
+//       "firstName": <string>,
+//       "lastName": <string>
+//     }
+//
+// If the embedded message type is well-known and has a custom JSON
+// representation, that representation will be embedded adding a field
+// `value` which holds the custom JSON in addition to the `@type`
+// field. Example (for message [google.protobuf.Duration][]):
+//
+//     {
+//       "@type": "type.googleapis.com/google.protobuf.Duration",
+//       "value": "1.212s"
+//     }
+//
+message Any {
+  // A URL/resource name that uniquely identifies the type of the serialized
+  // protocol buffer message. This string must contain at least
+  // one "/" character. The last segment of the URL's path must represent
+  // the fully qualified name of the type (as in
+  // `path/google.protobuf.Duration`). The name should be in a canonical form
+  // (e.g., leading "." is not accepted).
+  //
+  // In practice, teams usually precompile into the binary all types that they
+  // expect it to use in the context of Any. However, for URLs which use the
+  // scheme `http`, `https`, or no scheme, one can optionally set up a type
+  // server that maps type URLs to message definitions as follows:
+  //
+  // * If no scheme is provided, `https` is assumed.
+  // * An HTTP GET on the URL must yield a [google.protobuf.Type][]
+  //   value in binary format, or produce an error.
+  // * Applications are allowed to cache lookup results based on the
+  //   URL, or have them precompiled into a binary to avoid any
+  //   lookup. Therefore, binary compatibility needs to be preserved
+  //   on changes to types. (Use versioned type names to manage
+  //   breaking changes.)
+  //
+  // Note: this functionality is not currently available in the official
+  // protobuf release, and it is not used for type URLs beginning with
+  // type.googleapis.com. As of May 2023, there are no widely used type server
+  // implementations and no plans to implement one.
+  //
+  // Schemes other than `http`, `https` (or the empty scheme) might be
+  // used with implementation specific semantics.
+  //
+  string type_url = 1;
+
+  // Must be a valid serialized protocol buffer of the above specified type.

+// just annotations which may cause code to be generated slightly differently
+// or may contain hints for code that manipulates protocol messages.
+//
+// Clients may define custom options as extensions of the *Options messages.
+// These extensions may not yet be known at parsing time, so the parser cannot
+// store the values in them.  Instead it stores them in a field in the *Options
+// message called uninterpreted_option. This field must have the same name
+// across all *Options messages. We then use this field to populate the
+// extensions when we build a descriptor, at which point all protos have been
+// parsed and so all extensions are known.
+//
+// Extension numbers for custom options may be chosen as follows:
+// * For options which will only be used within a single application or
+//   organization, or for experimental options, use field numbers 50000
+//   through 99999.  It is up to you to ensure that you do not use the
+//   same number for multiple options.
+// * For options which will be published and used publicly by multiple
+//   independent entities, e-mail protobuf-global-extension-registry@google.com
+//   to reserve extension numbers. Simply provide your project name (e.g.
+//   Objective-C plugin) and your project website (if available) -- there's no
+//   need to explain how you intend to use them. Usually you only need one
+//   extension number. You can declare multiple options with only one extension
+//   number by putting them in a sub-message. See the Custom Options section of
+//   the docs for examples:
+//   https://developers.google.com/protocol-buffers/docs/proto#options
+//   If this turns out to be popular, a web service will be set up

+// 3339](https://www.ietf.org/rfc/rfc3339.txt) date strings.
+//
+// # Examples
+//
+// Example 1: Compute Timestamp from POSIX `time()`.
+//
+//     Timestamp timestamp;
+//     timestamp.set_seconds(time(NULL));
+//     timestamp.set_nanos(0);

+//     gettimeofday(&tv, NULL);
+//
+//     Timestamp timestamp;
+//     timestamp.set_seconds(tv.tv_sec);

+//     timestamp.set_nanos((INT32) ((ticks % 10000000) * 100));
+//
+// Example 4: Compute Timestamp from Java `System.currentTimeMillis()`.
+//
+//     long millis = System.currentTimeMillis();
+//
+//     Timestamp timestamp = Timestamp.newBuilder().setSeconds(millis / 1000)

+//     Timestamp timestamp =
+//         Timestamp.newBuilder().setSeconds(now.getEpochSecond())
+//             .setNanos(now.getNano()).build();
+//
+// Example 6: Compute Timestamp from current time in Python.
+//
+//     timestamp = Timestamp()
+//     timestamp.GetCurrentTime()
+//
+// # JSON Mapping
+//
+// In JSON format, the Timestamp type is encoded as a string in the
+// [RFC 3339](https://www.ietf.org/rfc/rfc3339.txt) format. That is, the
+// format is "{year}-{month}-{day}T{hour}:{min}:{sec}[.{frac_sec}]Z"
+// where {year} is always expressed using four digits while {month}, {day},
+// {hour}, {min}, and {sec} are zero-padded to two digits each. The fractional
+// seconds, which can go up to 9 digits (i.e. up to 1 nanosecond resolution),
+// are optional. The "Z" suffix indicates the timezone ("UTC"); the timezone
+// is required. A proto3 JSON serializer should always use UTC (as indicated by
+// "Z") when printing the Timestamp type and a proto3 JSON parser should be
+// able to accept both UTC and other timezones (as indicated by an offset).
+//
+// For example, "2017-01-15T01:30:15.01Z" encodes 15.01 seconds past
+// 01:30 UTC on January 15, 2017.
+//
+// In JavaScript, one can convert a Date object to this format using the
+// standard
+// [toISOString()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString)
+// method. In Python, a standard `datetime.datetime` object can be converted
+// to this format using
+// [`strftime`](https://docs.python.org/2/library/time.html#time.strftime) with
+// the time format spec '%Y-%m-%dT%H:%M:%S.%fZ'. Likewise, in Java, one can use
+// the Joda Time's [`ISODateTimeFormat.dateTime()`](
+// http://joda-time.sourceforge.net/apidocs/org/joda/time/format/ISODateTimeFormat.html#dateTime()
+// ) to obtain a formatter capable of generating timestamps in this format.
