Flat high curve suggests metric or index mismatch. - Reorder prompt headers. If ΔS spikes, fix schema or anchors. 3) **Apply the module** - Retrieval drift → BBMC plus Data Contracts. - Reasoning collapse → BBCR bridge plus BBAM variance clamp. - Dead ends in long runs → BBPF alternate path. 4) **Verify** - Coverage to target section ≥ 0.70. - λ convergent across three paraphrases and two seeds. ## Typical breakpoints and the right fix - **Metric mismatch** - Corpus built with cosine but class uses dot or L2. Normalization tests raise ΔS while recall looks fine. - Action: rebuild class with correct distance or normalize embeddings at write and query. See [Embedding ≠ Semantic](https://github.com/onestardao/WFGY/blob/main/ProblemMap/embedding-vs-semantic.md) and [Retrieval Playbook](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-playbook.md). - **Dimension or encoder swap** - Import accepts new vectors then recall collapses for only the new span. - Action: lock encoder version in the schema via a data contract, re-index the affected classes. See [Data Contracts](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md). - **HNSW tuning traps** - efSearch too low for your k, or M too small for dense corpora. Symptoms are plateaued recall and unstable top-k ordering. - Action: raise efSearch to 2–4×k, validate with reranker sandwiched on top. See [Rerankers](https://github.com/onestardao/WFGY/blob/main/ProblemMap/rerankers.md) and [Retrieval Playbook](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-playbook.md). - **Shard or replica consistency** - Some queries never surface fresh writes. Multi-tenant classes or replicas returning stale reads. - Action: align consistency level during validation, confirm write-ack before eval. See [Live Monitoring for RAG](https://github.com/onestardao/WFGY/blob/main/ProblemMap/ops/live_monitoring_rag.md). - **Hybrid search weighting** - BM25 plus vector performs worse than vector alone. Query template or HyDE text dominates vector term. - Action: run the split test. If the hybrid flip is the cause, re-balance weights and clean prompt glue. See [Query Parsing Split](https://github.com/onestardao/WFGY/blob/main/ProblemMap/patterns/pattern_query_parsing_split.md). - **Vectorstore fragmentation** - Multiple classes with near-duplicate schemas. Coverage drops while ΔS stays flat high across k. - Action: merge or route by class key, then rebuild a single authoritative index. See [Vectorstore Fragmentation](https://github.com/onestardao/WFGY/blob/main/ProblemMap/patterns/pattern_vectorstore_fragmentation.md). - **Tokenization and filter mismatch** - Filters on properties return empty or unstable results. Analyzer not aligned with corpus language or case rules. - Action: lock analyzers in a data contract and re-ingest with normalized fields. See [Data Contracts](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md). - **Batch import and boot order** - First production call after deploy fails or returns zero results although objects exist. - Action: enforce bootstrap fence and idempotent batcher. See [Debug Playbook](https://github.com/onestardao/WFGY/blob/main/ProblemMap/ops/debug_playbook.md). ## Observability probes - **k-sweep curve**: run k in 5, 10, 20 and plot ΔS. A flat high curve means metric or class routing fault. - **Anchor control**: compare ΔS against a golden anchor set for one class. If only a class fails, route or rebuild. - **Hybrid toggle**: run vector only and hybrid with equal weight. If hybrid degrades, fix query split or weight. - **Reranker audit**: with a strong reranker, recall should improve monotonically while ΔS falls. If not, rebuild index. ## Escalate when - ΔS stays above 0.60 for the golden questions after metric and efSearch corrections. - Coverage cannot reach 0.70 even with a reranker and clean anchors. - Fresh writes are invisible for more than one minute under your consistency setting.
