Description

Subgraph runner has some code duplication and a lot of if-else-ish code. We should try to improve it by making some concerns more isolated and the error more testable.

This is probably going to require several iterations on different parts but the sooner we start the sooner we finish.

As @lutter pointed out, this last PR added some more code duplication which doesn't help https://github.com/graphprotocol/graph-node/pull/4916#issuecomment-1839289761

Research direction

Start by locating the subgraph runner and reviewing the duplication discussed in PR #4916 and its linked comment. Identify the separate concerns and error paths before deciding on the refactor shape; done means the duplication and if-else-heavy logic are reduced and the error behavior is covered by tests.
