v1.0.0 — free-path evaluation program + identity + failure injection

production-rag v1.0.0

Clone-only free-path flagship. Still $0. Still no Vercel. Never cite production-rag.vercel.app (Ipsura).

What shipped

• Free-path eval program n=52 (golden-free-path.jsonl) with slices answerable / unanswerable / filter / hybrid-vs-dense
• Difficulty predicates: CI fails if a ranking slice is all trivial rank-1
• Scorecard HTML+JSON ablation dense/sparse/hybrid/hybrid_rerank labeled plumbing, billed=false
• HTTP transcripts: grounded, refuse, title=Filtering, stream; failure path with CACHE_ENABLED=false
• /v1/ready collection identity: embedder_id, chunker_version, doc_count, corpus_hash
• Cache key includes corpus identity (no cross-hit); typed wrong_collection
• Provider/store failures → 503 with refused: false (never soft refuse)
• Local load harness: docs/assets/load.json (n=100, honest single-process note)
• ADR-0014 corpus hash in cache key; CASESTUDY ≥1500 words

Still PLANNED

• Auth / rate limit (P5)
• Hosted Qdrant / multi-worker Redis cache
• Hosted-provider quality baseline (billed run with named providers)
• Public P1 host (will not ship; clone-only is intentional)
