[v0.39.2] - 2026-07-17

LibraryManagerAbstract.is_crate_loaded(*, library_id, fingerprint) — public query over the per-library crate-fingerprint bookkeeping that already backs load_from_crate's idempotency. A True answer means the library's ClassRegistry holds the crate's dynamic classes, so callers can hydrate within an existing scope instead of opening a fresh one — preserving dynamic-class identity with instances that scope already produced. This is the core half of the fix for the PipeParallel same-concept combine failing over Temporal with expected X, got X pydantic model-type errors.

PipeCompose construct: whole-stuff copies into native fields now convert in every promised case. { from = "..." } referencing a whole native stuff used to hand the content wrapper (TextContent, ListContent, ...) to the composed field in several cases, failing the dry-run runnable gate on correct methods. Three gaps fixed: optional (non-required) fields never converted (the Optional[X] annotation defeated the type detection), list-of-text targets dumped each item as a {"text": ...} dict instead of extracting the string, and scalar wrappers other than Text were not handled at all. The conversion matrix now covers Text → text, Number → number, YesNo → boolean, and Date → date, for both required and optional target fields, scalar and list-item positions — including nullable list items (list[str | None]), which normalize like their non-nullable counterparts. Unconvertible list items now raise a clear StructuredContentComposerTypeError instead of surfacing as a cryptic pydantic error downstream. One fidelity guard: copying a Date that carries a time of day into a bare date field raises instead of silently dropping the time and its UTC offset (breaking: this case previously truncated silently).
