Covers span attributes, a smoke-test workflow, a sanitized log record template, and a contract-area verification table.https://llmapireliability.com/posts/response-contract-evidence-for-llm-api-failover/Mon, 08 Jun 2026 08:57:16 +0000https://llmapireliability.com/posts/response-contract-evidence-for-llm-api-failover/A practical guide to the response-contract fields, error shapes, and cross-provider parameter differences that operators should verify before wiring up an LLM API failover path.https://llmapireliability.com/posts/fallback-decision-logs-for-cometapi-gateway-calls/Fri, 05 Jun 2026 06:36:53 +0000https://llmapireliability.com/posts/fallback-decision-logs-for-cometapi-gateway-calls/A practical guide for operators who want to design, emit, and interpret fallback decision logs when CometAPI gateway calls fail or degrade. Covers log field design, decision taxonomy, smoke-test workflow, and the contract areas you must verify in the official docs.
