Self-note: crossreference with changes in #15851 - there's a lot of overlap here. Might be best to DRY it out, especially since we may not actually want to stick with the "empty context" solution.

TODO: heavy cleanup needed here - we probably need tests for both predictFromCorrections AND for correctAndEnumerateWithoutTraversals.

See #15907 - this is somewhat similar to the compositeIntermediatePredictions function defined therein. May be worth hoisting, then polishing up later in the PR chain?

In this PR, the generalization work from #15919 and #16028 pay off, allowing custom and legacy models to leverage the vast majority of code that was already handling our first-class models, such as those based on the TrieModel wordlist pattern.
