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?

Aims: - improve consistency between Traversal-based models and legacy/custom models without Traversals - improve ability to unit-test construction of the correction-sequence directly, as a smaller, individual unit
