pub fn temporal_api_sources(engine: &Engine) -> Vec<ApiSource>Expand description
Compute the list of Scalar multi-source entries for temporal versioning.
Returns one ApiSource per distinct temporal version boundary across all
loaded specs, plus one now source (slug NOW_SLUG) that uses no effective
query (evaluation instant = request time). That entry is first (Scalar default),
then boundaries in descending chronological order (newest first).
If there are no temporal version boundaries (all specs are unversioned), returns a single now entry.
