# Sources and implementation references - v2.0 final ## Final-release note v2.0 introduces no new runtime dependency or external architectural component. The final changes are benchmark alignment, UI/documentation polish, and local release-verification tooling. Existing official/source references below continue to document the underlying Gradio, FastAPI, Gemini, LangGraph, Qdrant and retrieval behavior. No tutorial source code is copied into RAGForge. The requested projects were used as architectural inspiration/checklists. ## Requested reference projects 1.

They are not presented as universal claims that reranking is ineffective or that one evaluation design is optimal for every corpus. The explicit reranker ablation remains available so the decision can be revisited when corpus size/difficulty changes. ## v1.6 evaluation-driven policy Insight synthesis, hard-mode benchmark cases, table citation semantics, chunk-level reranker labels, profile comparison and evaluation-history deltas are RAGForge-specific engineering additions derived from the project's own observed evaluation gaps. They are not claims that one routing taxonomy or benchmark design is universally optimal. ## v1.7 evaluation-policy note v1.7 does not add a new external dependency or benchmark dataset. The new policies are derived from RAGForge's own auditable v1.6 run data: perfect source/chunk ablation quality with large reranker latency, a false-negative missing-answer case, and Markdown citation-coverage artifacts. ## v1.8 evaluation-policy note v1.8 adds no new external benchmark or hosted dependency. The context-budget policy is derived from RAGForge's own v1.7 auditable run: focused QA retained 100% source Recall@5/Hit@1/MRR while source Precision@5 remained roughly 47%, and generation dominated node latency. The new ablation therefore tests whether removing the focused-query distractor tail preserves recall before treating the optimization as beneficial. ## v1.9 implementation note v1.9 adds no external runtime dependency and no new third-party architecture source. Adaptive budgets, sentence compression, scale stress, workspace diagnostics and readiness scoring are implemented locally on top of the existing retrieval/evaluation stack. The scale harness reuses existing embedding vectors rather than calling an embedding or generation API.
