Package agecrypt is lore's encryption boundary for portable artifacts: it wraps a whole serialized artifact byte stream in an age envelope (and reverses it), so the exported file is encrypted at rest and in transit.

Package cache provides a caching decorator around an app.Generator: it serves a previously synthesized answer from an app.AnswerCache when the same question is asked over the same grounding, skipping the LLM round-trip.

Package docx is an Extractor for Word .docx files.

Package extract turns supported raw content into plain text for chunking.

Package fs is a filesystem Source: it walks a path (file or directory) and yields each regular, non-hidden file as a SourceItem whose content type is detected from the extension.

Package httpjson is the shared HTTP-JSON plumbing for lore's provider adapters (the OpenAI-compatible embed/chat client and the Cohere-style reranker): a POST of a JSON body, decode of a 2xx JSON response, bearer or api-key auth, and automatic retry of transient 429/503 responses honoring Retry-After.

Package memstore provides in-memory reference implementations of the persistence ports.

Package openai adapts the Embedder and Generator ports to any OpenAI-compatible HTTP API (OpenAI, Ollama's /v1, vLLM, LM Studio, OpenRouter).

Package pdf is an Extractor for PDF files, backed by the pure-Go github.com/ledongthuc/pdf (no cgo, so the static-binary and cross-compile goals hold).

Package rerank adapts the app.RerankProvider port to a Cohere-style rerank HTTP API (POST /rerank with {model, query, documents, top_n} → {results: [{index, relevance_score}]}), the de-facto standard that Cohere, Jina, Voyage, and others conform to.

Package sqlite is a persistent backend: one SQLite database file holding all collections, documents, chunks, and vectors.

Package tiktoken is the TokenCounter adapter: it counts tokens with a pure-Go, offline tiktoken BPE codec (o200k_base — the encoding text-embedding-3 and gpt-4o use).

Package xlsx is an Extractor for Excel .xlsx files.
