LLM Providers: Guardrails and Fix Patterns

A compact hub to stabilize provider-specific failures without changing your infra. Use this when symptoms look “model problem” but root cause is actually schema, retrieval, or orchestration.

Open these first

Visual map and recovery: RAG Architecture & Recovery
End-to-end retrieval knobs: Retrieval Playbook
Why this snippet (traceability schema): Retrieval Traceability
Ordering control: Rerankers
Embedding vs meaning: Embedding ≠ Semantic
Hallucination and chunk boundaries: Hallucination
Long chains and entropy: Context Drift, Entropy Collapse
Structural collapse and recovery: Logic Collapse
Snippet and citation schema: Data Contracts
Live ops: Live Monitoring for RAG, Debug Playbook
Boot order issues: Bootstrap Ordering, Deployment Deadlock, Pre-Deploy Collapse

Core acceptance

ΔS(question, retrieved) ≤ 0.45
Coverage ≥ 0.70 for the target section
λ remains convergent across three paraphrases and two seeds
E_resonance stays flat through long windows

Typical provider symptoms → exact fix

Symptom	Likely cause	Open this
JSON mode breaks, invalid objects	schema too loose or nested tool calls	Data Contracts, Logic Collapse
Tool calls loop or stall	agent role drift, missing timeouts	Multi-Agent Problems, role-drift deep dive
High similarity yet wrong snippet	metric mismatch or fragmented store	Embedding ≠ Semantic, Vectorstore Fragmentation
Answers flip between runs	prompt headers reorder and λ flips	Context Drift, Retrieval Traceability
Hybrid retrievers worse than single	query parsing split, mis-weighted rerank	Query Parsing Split, Rerankers
Jailbreaks or bluffing	overconfidence and missing fences	Bluffing Controls, Retrieval Traceability

Fix in 60 seconds

Measure ΔS
Compute ΔS(question, retrieved) and ΔS(retrieved, expected anchor).
Stable < 0.40, transitional 0.40–0.60, risk ≥ 0.60.
Probe λ_observe
Vary k and prompt headers. If λ flips, lock the schema and apply a BBAM variance clamp.
Apply the module

Retrieval drift → BBMC + Data Contracts
Reasoning collapse → BBCR bridge + BBAM
Dead ends in long runs → BBPF alternate paths

Verify
Coverage ≥ 0.70 on three paraphrases. λ convergent on two seeds.

Provider-level gotchas checklist

Truncation. Confirm token accounting for system + tools + hidden preambles. If truncated, compress citations through Data Contracts.
Streaming chunk boundaries. Do not parse partial JSON while λ is unstable. Buffer until BBAM settles.
Temperature and top-p. If ΔS is already high, reduce entropy. If retrieval is sparse, raise recall through rerankers instead of temperature.
Multi-model routing. Keep traceability stable when swapping GPT, Claude, Gemini, Mistral. Use the same snippet schema and citation header across providers.
Rate limits and retries. Backoff with idempotent ops. Never rebuild indexes inside retry loops.
Eval parity. Run the same acceptance on all providers to avoid overfitting a single model.
