Add langextract field-extraction tab (optional, stub-tested)

feat: section_path metadata + section records, SME vocab expansion, optional pre-refusal gate (VDGR + doc-intel adoptions)

feat: naive fixed-chunk baseline strategy (eval + Compare panel 0) - the honest before picture

final AB driver: fixed probe doc-resolution + nemotron lane + VL-reranker before/after

fix: drivers phase_fail unbound $2 crash on fail path

test: CC-BY-NC variant A/B GPU driver (nemotron lane + jina listwise)

fix: nemotron build branch token-matrix bug (CPU roundtrip proof); eval k==5 double-count fix + MRR@5 metric; transformers>=4.57

feat: NC best-in-class variants (nemotron-colembed lane, jina-reranker-v3.5 listwise); fix demo chips gitignored away

test: Sept-2026 upgrade A/B GPU driver

feat(upgrades): zerank-2 text reranker tier + Tomoro ColQwen3 visual lane swap + Qwen3-VL-Reranker page reranking (A/B flags)

feat: per-document summaries (grader scope injection + summary records) and quick-ingest mode

feat(demo): follow-up condensation, clickable demo chips, answer feedback logging

fix(smoke): disable tqdm/HF progress bars in job env (stalled log transport at embedding/visual stages)

feat(smoke): real-TM GPU driver (135-page US Army TM-5-811-6, vision lanes + LLM answer phases)

feat(app): side-by-side comparison panel (4 strategies, citations, page images, opt-in LLM answers); pin gradio 5.50.0

feat(scripts): hard-PDF GPU smoke driver

feat(scripts): adversarial hard-PDF suite builder + CPU test overrides

chore(smoke): raise-from in driver; add stub test and synthetic PDF builder

fix: visual_lane torch import, real HybridChunker usage, driver Phase B counts persisted vision records

driver: install fpdf2, escape newlines in generated phase code, compile-check generated code

fix: plain-dict chunks from Qdrant ScoredPoints; doc_name/score in chunk payload; retrieval smoke 3/3

factory-rag full rebuild: all modules, docs, smoke driver
