From 8e9057b5f8e418069c64653ec898e63864157c40 Mon Sep 17 00:00:00 2001 From: Atti Ur Rehman Date: Thu, 18 Jun 2026 13:23:07 +0300 Subject: [PATCH 1/6] feat(production): full agent production layer (#21) 7 layers on top of the working LangGraph incident graph: 1 Observability Langfuse trace per incident, spans per node, session_id stitches the run across the human pause 2 Evaluation agent eval suite (triage acc, routing=1.0, synthesis judge, e2e) CI-gated, blocks merge 3 Guardrails action authorization in code, alert-injection scan, Slack payload validation, low-confidence abstain 4 Cost cost per incident across 4 nodes + Tavily, per-account cap, runaway circuit breaker 5 Durability Redis checkpointer, resume from node after cold start, idempotent Slack action, 48h approval TTL 6 Reliability recursion + feedback-loop caps, node timeouts, retries w/ backoff, fallback model, Tavily breaker, DLQ 7 Security immutable action audit log w/ approver identity, secrets hygiene, PII
