nx_beerqa_fetch.nx -- fetch the BeerQA dev split (Stanford, beerqa.github.io) SOVEREIGNLY. BeerQA UNIFIES SQuAD(1-hop) + HotpotQA(2-hop) + newly-annotated 3-hop questions in ONE format tagged by `src` = the whole difficulty ladder in a single dataset (operator's explicit example). ⚠STATUS 2026-07-07: BLOCKED at the TLS HANDSHAKE (pinned via nx_fetch_probe, all 3 paths): TLS1.3, chrome fingerprint, AND TLS1.2 ALL fail at FAIL=HANDSHAKE(tls) -- so it is NOT DNS (resolves), NOT TCP (connects), NOT a TLS-version issue. The handshake reaches negotiation and dies = CERT-VALIDATION (Stanford CA/chain not in our Mozilla store, or an unsupported signature-alg) OR a required cipher/curve our client doesn't offer. Fixing it = a focused TLS arc (dump the ServerHello/cert stage, add the missing CA or cipher). NOT the fetcher's fault (paged/dynamic path proven on HF). ALTERNATIVE TAKEN: MuSiQue (2-4 hop, HARDER than BeerQA's 3-hop tier) is parquet-backed on HF and reachable -> nx_musique_fetch gives us a harder rung without the Stanford TLS arc. Keep this as the ready retry once the handshake is debugged. Run SOLO. expect_exit: 0 license_tier: ORIGINAL
