What is the value of org-blocker-hook?

A clarification re this part of my initial message:

> and refresh the settings, dependencies work.
This is misleading. I realized that dependencies *do* work consistently
in the minimal configuration. With the header line in the test file, I
can change the main task from TODO to STARTED (or to any of the other
non-done states), but I'm blocked from changing it to DONE.
But they still don't work with my usual configuration.
Apologies.

I don't know why it's nil. However, I've discovered a bit more. It
seems that the problem is that my settings in my org-config file:
(setq org-enforce-todo-dependencies t)
(setq org-agenda-dim-blocked-tasks 'invisible)
(setq org-enforce-todo-checkbox-dependencies t)
didn't prompt the required change in the value of org-blocker-hook.
With these lines in my org config file, the values of the three
variables are as expected, but the value of org-blocker-hook remains
nil, even if I stop and re-start emacs.
When I change the value of org-enforce-todo-dependencies using
customize, then the value of org-blocker-hook is what it should be, and
the dependencies work, even if I stop and re-start emacs.
So presumably something else in my config file is keeping
org-blocker-hook from being re-set?
I'd prefer not to use the customize function, so I'd hoped to set it in
my config file.
Thanks, and apologies for not sorting through this a bit more before
the initial post.

You need to set these variables before org.el is loaded.

In fact, we need a FAQ about this issue:
Several variables in Org must already be set a load time.
This is one of the reasons why you should not use (require 'org)
in your setup, but better only (require 'org-install).
However, org.el will also get loaded when you require some
other org-... file, for example an add-on from the contrib
directory.
The right way is therefore *always* this (a general Emacs truth).
First, set all your variables. Then load the package.
In this particular example, the problem is the following:
Setting the variables for the todo dependencies triggers
adding functions to org-blocker-hook, at load time for org.el.
I *could* do a different implementation, where the functions
are always in the blocker hook, but are only active when the
variables are set. However, the problem is then that it is
difficult to see from the outside if the hook is doing something,
and I want to use that knowledge to avoid overhead in the
agenda for people who do not use todo dependencies.

Hi Carsten --
Thanks for the troubleshooting, and thanks also for this write-up. In
particular ---

I was setting the variables before (require 'org-install), but I found
an earlier instance of (require 'org-xxx). It's inspired me to clean up
and organize my init files.

Excellent, I was wondering why I couldn't get this function to work.

FYI, I'd actually suggest this approach. I think the number of people
that will get confused by variable-and-loading-ordering will be far
greater than the number of people trying to figure out why the function
isn't doing anything (especially if in the function documentation it
says a variable must be set for it to perform any actions).
I too immediately tried the new TODO dependencies after the last release
announcement and couldn't get it to work... Old habit of performing
'(require ...)' ahead of the variable settings.

I don't think this is easily possible in all cases, but I have made
this chance now for the dependency variables. Causes some overhead
when entering org-mode, but only trivial.
But there are more such variables,
org-replace-disputed-keys
org-tab-follows-link
org-return-follows-link
org-mouse-1-follows-link
These all have to do with keymaps I am setting up al load time.
