Live Production Incident Simulator
"It's 03:00 AM. Production is down. Has this happened before?"
Target: CockroachDB Cloud • Region: ap-southeast-3
SRE teams burn hours debugging recurring outages, while standard AI RAG systems naively repeat past failed fixes or ignore version drift. DejaView solves this with distributed vector memory in CockroachDB and a deterministic safety gate that hard-blocks historical failures before invoking AWS Bedrock (Claude Sonnet 5).

The Naive Vector Fallacy
Standard vector DBs measure text similarity (0.95 cosine), ignoring outcome history and environment drift.
Re-debugs from scratch or defaults to restarting app (causes downtime).

Deterministic Safety Gate
Evaluates historical outcomes in CockroachDB. Hard-blocks past failures and flags environment version drift before invoking LLMs.

Grounded SRE Remediation (AWS Bedrock Claude Sonnet 5)
### 🪳 Grounded Incident Remediation Plan (AWS Bedrock — Claude Sonnet 5)
**Incoming Alert**: `ConnectionPoolExhaustedException: client connection timeout after 30000ms in pgx pool during peak traffic`
**1. Root Cause Analysis**:
- **Connection Pool Timeout under Peak Traffic**: PostgreSQL connection pool max_connections capped at 20 while concurrency spiked to 150 requests/sec.
**2. Verified Remediation Actions**:
- Apply fix from **CockroachDB Memory #inc-101-conn-pool**: `Increased pool max_connections to 100 and set idleTimeoutMillis to 10000ms.` (✅ Environment fingerprint verified.)
