I have some progress.

The delta was not working because the TS was in development mode,
while the application was in production mode.
TS was trying to access a non-existent production config which we
could not generate. This incorrect approach worked in the earlier
versions of the TS for unknown reasons though :)

And as for production-mode config:

Inside the configuration.rb's build method the
ThinkingSphinx.context.indexed_models is always empty in production
mode.

ThinkingSphinx.context initializes itself with these two methods:
load_models and add_indexed_models in respective order.

The .constantize method in load_models always throws NameError
exception on every model in production mode, meaning there is not a
single model initialized at that moment. I'm not competent enough to
determine if this is the correct behavior or not, and what to do about
it.
And add_index_models, consequently (or not) cant see a single indexed
model.

I just cant understand, by looking at the code, why the development
mode works correctly and the production mode does not.

Can you please give some advice on where i can try to look next?
