Use contains_content_type_gated_content attribute, rather than the graded attribute, to determine if the content type gating paywall should be displayed. (#349)

The issue was that items with the graded attribute are not always going to be paywalled by content type gating.

+# Courseware Page Decisions
+
+## Courseware data loading
+
+Today we have strictly hierarchical courses - a course contains sections, which contain sequences, which contain units, which contain components.
+
+In creating the courseware pages of this app, we needed to choose how often we fetch data from the server.  If we fetch it once and try to get the whole course, including all the data we need in its entire hierarchy, then the request will take 30+ seconds and be a horrible UX.  If we try to fetch too granularly, we risk making hundreds of calls to the LMS, incuring both request overhead and common server-side processing that needs to occur for each of those requests.
+
+Instead, we've chosen to load data via the following:
+
+- The course blocks API (/api/courses/v2/blocks) for getting the overall structure of the course (limited data on the whole hierarchy)
+- The course metadata API (/api/courseware/course) for detailed top-level data, such as dates, enrollment status, info for tabs across the top of the page, etc.
+- The sequence metadata API (/api/courseware/sequence) for detailed information on a sequence, such as which unit to display, any banner messages, whether or not the sequence has a prerequisite, if it's an exam, etc.
+- The xblock endpoint (http://localhost:18000/xblock/:block_id) which renders HTML for an xBlock by ID, used to render Unit contents.  This HTML is loaded into the application via an iFrame.
+
+These APIs aren't perfect for our usage, but they're getting the job done for now.  They weren't built for our purposes and thus load more information than we strictly need, and aren't as performant as we'd like.  Future milestones of the application may rely on new, more performant APIs (possibly BFFs)
+
+## Unit iframing
+
+We determined, as part of our project discovery, that in order to deliver value to users sooner, we would iframe in content of units.  This allowed us to avoid rebuilding the UI for unit/component xblocks in the micro-frontend, which is a daunting task.  It also allows existing custom xblocks to continue to work for now, as they wouldn't have to be re-written.
+
+A future iteration of the project may go back and pull the unit rendering into the MFE.
+
+## Strictly hierarchical courses
+
+We've also made the assumption that courses are strictly hierarchical - a given section, sequence, or unit doesn't have multiple parents.  This is important, as it allows us to navigate the tree in the client in a deterministic way.  If we need to find out who the parent section of a sequence is, there's only one answer to that question.
+
+## Determining which sequences and units to show
+
+The courseware URL scheme:
+
+`/course/:courseId(/:sequenceId(/:unitId))`
+
+Sequence ID and unit ID are optional.
+
+Today, if the URL only specifies the course ID, we need to pick a sequence to show.  We do this by picking the first sequence of the course (as dictated by the course blocks API) and update the URL to match.  _After_ the URL has been updated, the application will attempt to load that sequence.
+
+Similarly, if the URL doesn't contain a unit ID, we use the `position` field of the sequence to determine which unit we want to display from that sequence.  If the position isn't specified in the sequence, we choose the first unit of the sequence.  After determining which unit to display, we update the URL to match.  After the URL is updated, the application will attempt to load that unit via an iFrame.
+
+## "Container" components vs. display components
+
+This application makes use of a few "container" components at the top level - CoursewareContainer and CourseHomeContainer.
+
+The point of these containers is to introduce a layer of abstraction between the UI representation of the pages and the way their data was loaded, as described above.
+
+We don't want our Course.jsx component to be intimately aware - for example - that it's data is loaded via two separate APIs that are then merged together.  That's not useful information - it just needs to know where it's data is and if it's loaded.  Furthermore, this layer of abstraction lets us normalize field names between the various APIs to let our MFE code be more consistent and readable.  This normalization is done in the src/data/api.js layer.
+
+## Navigation
+
+Course navigation in a hierarchical course happens primarily via the "sequence navigation".  This component lets users navigate to the next and previous unit in the course, and also select specific units within the sequence directly.  The next and previous buttons (SequenceNavigation and UnitNavigation) delegate decision making up the tree to CoursewareContainer.  This is an intentional separation of concerns which should allow different CoursewareContainer-like components to make different decisions about what it means to go to the "next" or "previous" sequence.  This is in support of future course types such as "pathway" courses and adaptive learning sequences.  There is no actual code written for these course types, but it felt like a good separation of concerns.

+# Course Home Decisions
+
+The course home page is not complete as of this writing.
+
+It was added to the MFE as a proof of concept for the Engagement theme's Always Available squad, as they were intending to do some work in the legacy course home page in the LMS, and we wanted to understand whether it would be more easily done in this application.
+
+It uses the same APIs as the courseware page, for the most part.  This may not always be the case, but it is for now.  Differing API shapes may be faster for both pages.

@@ -0,0 +1,9 @@
+## Model Store
+
+Because we have a variety of models in this app (course, section, sequence, unit), we use a set of generic 'model store' reducers in redux to manage this data.  Once loaded from the APIs, the data is put into the model store by type and by ID, which allows us to quickly access it in the application.  Furthermore, any sub-trees of model children (like "items" in the sequence metadata API) are flattened out and stored by ID in the model-store, and their arrays replaced by arrays of IDs.  This is a recommended way to store data in redux as documented here:
+
+https://redux.js.org/faq/organizing-state#how-do-i-organize-nested-or-duplicate-data-in-my-state
+
+Different modules of the application maintain individual/lists of IDs that reference data stored in the model store.  These are akin to indices in a database, in that they allow you to quickly extract data from the model store without iteration or filtering.  
+
+A common pattern when loading data from an API endpoint is to use the model-store's redux actions (addModel, updateModel, etc.) to load the "models" themselves into the model store by ID, and then dispatch another action to save references elsewhere in the redux store to the data that was just added.  When adding courses, sequences, etc., to model-store, we also save the courseId and sequenceId in the 'courseware' part of redux.  This means the courseware React Components can extract the data from the model-store quickly by using the courseId as a key: `state.models.courses[state.courseware.courseId]`.  For an array, it iterates once over the ID list in order to extract the models from model-store.  This iteration is done when React components' re-render, and can be done less often through memoization as necessary.

+# Components Own Their Own Loading State
+
+Currently, the majority of the components in the component tree for both Courseware and CourseHome own their own loading state.  This means that they're _aware_ of the loading status (loading, loaded, failed) of the resources they depend on, and are expected to adjust their own rendering based on that state.
+
+The alternative is for a given component's parent to be responsible for this logic.  Under normal circumstances, if the parents were responsible, it would probably result in simpler code in general.  A component could just take for granted that if it's being rendered, all it's data must be ready.  
+
+*We think that that approach (giving the parents responsibility) isn't appropriate for this application.*
+
+We expect - in the longer term - that different courses/course staff may switch out component implementations.  Use a different form of SequenceNavigation, for instance.  Because of this, we didn't want parent components to be too aware of the nature of their children.  The children are more self-contained this way, though we sacrifice some simplicity for it.
+
+If, for instance, the Sequence component renders a skeleton of the SequenceNavigation, the look of that skeleton is going to be based on an understanding of how the SequenceNavigation renders itself.  If the SequenceNavigation implementation is switched out, that loading code in the Sequence may be wrong/misleading to the user.  If we leave the loading logic in the parent, we then have to branch it for all the types of SequenceNavigations that may exist - this violates the Open/Closed principle by forcing us to update our application when we try to make a new extension/implementation of a sub-component (assuming we have a plugin/extension/component replacement framework in place).
+
+By moving the loading logic into the components themselves, the idea is to allow a given component to render as much of itself as it reasonably can - this may mean just a spinner, or it may mean a "skeleton" UI while the resources are loading.  The parent doesn't need to be aware of the details.
+
+## Under what circumstances would we reverse this decision?
+
+If we find, in time, that we aren't seeing that "switching out component implementations" is a thing that's happening, then we can probably simplify the application code by giving parents the responsibility of deciding when to render their children, rather than keeping that responsibility with the children themselves.

+# Naming API functions and redux thunks
+
+Because API functions and redux thunks are two parts of a larger process, we've informally settled on some naming conventions for them to help differentiate the type of code we're looking at.
+
+## API Functions
+
+This micro-frontend follows a pattern of naming API functions with a prefix for their HTTP verb.
+
+Examples:
+
+`getCourseBlocks` - The GET request we make to load course blocks data.
+`postSequencePosition` - The POST request for saving sequence position.
+
+## Redux Thunks
+
+Meanwhile, we use a different set of verbs for redux thunks to differentiate them from the API functions.  For instance, we use the `fetch` prefix for loading data (primarily via GET requests), and `save` for sending data back to the server (primarily via POST or PATCH requests)
+
+Examples:
+
+`fetchCourse` - The thunk for getting course data across several APIs.
+`fetchSequence` - The thunk for the process of retrieving sequence data.
+`saveSequencePosition` - Wraps the POST request for sending sequence position back to the server.
+
+The verb prefixes for thunks aren't perfect - but they're a little more 'friendly' and semantically meaningful than the HTTP verbs used for APIs.  So far we have `fetch`, `save`, `check`, `reset`, etc.

+# Testing
+
+## Status
+Draft
+
+Let's live with this a bit longer before deciding it's a solid approach and marking this Approved.
+
+## Context
+We'd like to all be on the same page about how to approach testing, what is
+worth testing, and how to do it.
+
+## React Testing Library
+We'll use react-testing-library and jest as the main testing tools.
+
+This has some implications about how to test. You can read the React Testing Library's
+[Guiding Principles](https://testing-library.com/docs/guiding-principles), but the main
+takeaway is that you should be interacting with React as closely as possible to the way
+the user will interact with it.
+
+For example, they discourage using class or element name selectors to find components
+during a test. Instead, you should find them by user-oriented attributes like labels,
+text, or roles. As a last resort, by a `data-testid` tag.
+
+## Mocking data
+We'll use [Rosie](https://github.com/rosiejs/rosie) as a tool for building JavaScript objects.
+Our main use case for Rosie is to use factories in order to mock the data we'd like to fetch when rendering components.
+[axios-mock-adapter](https://www.npmjs.com/package/axios-mock-adapter) allows us to mock the response of an HTTP request.
+
+For example, we may use a factory to build a course metadata object:
+
+`const courseMetadata = Factory.build('courseMetadata');`
+
+Then we'd pass that `courseMetadata` object into an axios mock call:
+
+`axiosMock.onGet('example.com').reply(200, courseMetadata);`
+
+This way, when a component sends a GET request to `example.com` within the test's lifecycle, the request will be intercepted
+by the axios-mock-adapter, and the courseMetadata object will be returned.
+
+These factories should live within the data directories they intend to mock
+```
+courseware
+  | data
+      | __factories__
+          | courseMetadata.factory.js /* used to define the Rosie factory */
+      | api.js /* getCourseMetadata() lives here */
+```
+
+## What to Test
+We have not found exhaustive unit testing of frontend code to be worth the trouble.
+Rather, let's focus on testing non-obvious behavior.
+
+In essence: `test behavior that wouldn't present itself to a developer playing around`.
+
+Practically speaking, this means error states, interactive components, corner cases,
+or anything that wouldn't come up in a demo course. Something a developer wouldn't
+notice in the normal course of working in devstack.
+
+## Snapshots
+In practice, we've found snapshots of component trees to be too brittle to be worth it,
+as refactors occur or external libraries change.
+
+They can still be useful for data (like redux tests) or tiny isolated components.
+
+But please avoid for any "interesting" component. Prefer inspecting the explicit behavior
+under test, rather than just snapshotting the entire component tree.
