Module providers 

Provider test doubles: scripted LLM extractor, constant/recording embedders, and the dual-mode scripted NLI classifier.

Structs

ConstantEmbedder

Embedding provider that always returns the same vector regardless of input.

RecordingEmbedder

Embedding provider that records every embed call and returns a deterministic content-derived vector unique to the input text. Used to verify the extraction pipeline hands distinct embeddings to distinct facts (so Layer 2 dedup makes the right call). new returns the double together with the shared call-log handle so the test body can assert on it.

ScriptedExtractor

LLM extractor that pops pre-scripted results in FIFO order and counts invocations. When the script is exhausted, subsequent calls return an empty Vec (mirroring a provider that simply finds no facts) rather than erroring, so tests that do not care about the Nth call still pass.

Enums

ScriptedNliClassifier

Scripted NLI classifier with two modes:

ScriptedReranker

Scripted reranker, parity-shaped with ScriptedNliClassifier:
