Summary:
Depends on D19585. Ref T13164.
Almost all transactions require CAN_EDIT on the object, but they generally do not enforce this directly today. Instead, this is effectively enforced by Controllers, API methods, and EditEngine doing a `CAN_EDIT` check when loading the object to be edited.
A small number of transactions do not require CAN_EDIT, and instead require only a weaker/lesser permission. These are:
- Joining a project which you have CAN_JOIN on.
- Leaving a project which isn't locked.
- Joining a Conpherence thread you can see (today, no separate CAN_JOIN permission for Conpherence).
- Leaving a Conpherence thread.
- Unsubscribing.
- Using the special `!history` command from email.
Additionally, these require CAN_INTERACT, which is weaker than CAN_EDIT:
- Adding comments.
- Subscribing.
- Awarding tokens.
Soon, I want to add "disabling users" to this list, so that you can disable users if you have "Can Disable User" permission, even if you can not otherwise edit users.
It's possible this list isn't exhaustive, so this change might break something by adding a policy check to a place where we previously didn't have one. If so, we can go weaken that policy check to the appropriate level.
Enforcement of these special cases is currently weird:
- We mostly don't actually enforce CAN_EDIT in the Editor; instead, it's enforced before you get to the editor (in EditEngine/Controllers).
- To apply a weaker requirement (like leaving comments or leaving a project), we let you get through the Controller without CAN_EDIT, then apply the weaker policy check in the Editor.
- Some transactions apply a confusing/redundant explicit CAN_EDIT policy check. These mostly got cleaned up in previous changes.
Instead, the new world order is:
- Every transaction has capability/policy requirements.
- The default is CAN_EDIT, but transactions can weaken this explicitly they want.
- So now we'll get requirements right in the Editor, even if Controllers or API endpoints make a mistake.
- And you don't have to copy/paste a bunch of code to say "yes, every transaction should require CAN_EDIT".
Test Plan:
- Tried to add members to a Conpherence thread I could not edit (permissions error).
- Left a Conpherence thread I could not edit (worked properly).
- Joined a thread I could see but could not edit (worked properly).
- Tried to join a thread I could not see (permissions error).
- Implemented `requireCapabilites()` on ManiphestTransactionEditor and tried to edit a task (upgrade guidance error).

Summary:
Ref T12819. Some of the extensions "enrich" the document (adding more fields or relationships), while others "index" it (insert it into some kind of index for later searching).
Currently, these are all muddled under a single "index" phase. However, the Ferret extension cares about fields and relationships which other extensions may add.
Split this into two phases: "enrich" adds fields and relationships so other extensions can read them later if they want. "Index" happens after the document is built and has all the fields and relationships.
The specific problem this solves is that comments may not have been added to the document when the Ferret extension runs. By moving them to the "enrich" phase, the Ferret engine will be able to see and index comments.
Test Plan: Ran `bin/search index ...`, grepped for `indexFulltextDocument`.

Ref T12335. See that task for discussion. Here are the behavioral changes:
- Statuses can be flagged with `locked`, which means that tasks in that status are locked to further discussion and interaction.
- A new "CAN_INTERACT" permission facilitates this. For most objects, "CAN_INTERACT" is just the same as "CAN_VIEW".
- For tasks, "CAN_INTERACT" is everyone if the status is a normal status, and no one if the status is a locked status.
- If a user doesn't have "Interact" permission:
- They can not submit the comment form.
- The comment form is replaced with text indicating "This thing is locked.".
- The "Edit" workflow prompts them.
This is a mixture of advisory and hard policy checks but sholuld represent a reasonable starting point.

Summary:
Ref T9964. We have various kinds of secondary data on objects (like subscribers, projects, paste content, Owners paths, file attachments, etc) which is somewhat slow, or somewhat large, or both.
Some approaches to handling this in the API include:
- Always return all of it (very easy, but slow).
- Require users to make separate API calls to get each piece of data (very simple, but inefficient and really cumbersome to use).
- Implement a hierarchical query language like GraphQL (powerful, but very complex).
- Kind of mix-and-match a half-power query language and some extra calls? (fairly simple, not too terrible?)
We currently mix-and-match internally, with `->needStuff(true)`. This is not a general-purpose, full-power graph query language like GraphQL, and it occasionally does limit us.
For example, there is no way to do this sort of thing:
$conpherence_thread_query = id(new ConpherenceThreadQuery())
->setViewer($viewer)
// ...
->setNeedMessages(true)
->setWhenYouLoadTheMessagesTheyNeedProfilePictures(true);
However, we almost never actually need to do this and when we do want to do it we usually don't //really// want to do it, so I don't think this is a major limit to the practical power of the system for the kinds of things we really want to do with it.
Put another way, we have a lot of 1-level hierarchical queries (get pictures or repositories or projects or files or content for these objects) but few-to-no 2+ level queries (get files for these objects, then get all the projects for those files).
So even though 1-level hierarchies are not a beautiful, general-purpose, fully-abstract system, they've worked well so far in practice and I'm comfortable moving forward with them in the API.
If we do need N-level queries in the future, there is no technical reason we can't put GraphQL (or something similar) on top of this eventually, and this would represent a solid step toward that. However, I suspect we'll never need them.
Upshot: I'm pretty happy with "->needX()" for all practical purposes, so this is just adding a way to say "->needX()" to the API.
Specifically, you say:
```
{
"attachments": {
"subscribers": true,
}
}
```
...and get back subscriber data. In the future (or for certain attachments), `true` might become a dictionary of extra parameters, if necessary, and could do so without breaking the API.
Test Plan:
- Ran queries to get attachments.

This kind of code is generally bad because third-parties can't add new stuff, and it suggest something is kind of hacky in its architecture. Ideally, we would eventually get rid of almost all of this.
T9789 is a similar discussion of this for the next layer down (`TransactionEditor`) and plans to get rid of branchy-instanceofs there too.
Since I'm about to add more stuff here (for Custom Fields), split it out first so I'm not digging us any deeper than I already dug us.
