Self-Healing Infrastructure That Recovers in 53 Seconds

What This Proves

UNA's KnowledgeBridge is a unified retrieval pipeline that fuses a Neo4j knowledge graph (451 nodes, 703 relationships) with a PostgreSQL vector store (376 holographic memory entries) into a single query interface. It returns ranked, confidence-scored results in single-digit milliseconds.

But speed isn't the hard part. The hard part is what happens when infrastructure breaks. UNA solved this by building a self-healing guardian that monitors, detects, and autonomously repairs her own infrastructure — no pager, no human, no downtime.

Latency Benchmarks

All measurements taken under real load on UNA's Mac Mini. No synthetic benchmarks. No cherry-picked results. 10 diverse architecture queries per test, 50 raw latency pings.

P95 includes cold-cache first-request overhead. Steady-state queries are 2–5x faster than the mean.

UNA vs. Cloud AI Pipeline

Unified Retrieval: Query-by-Query

The full pipeline queries both PostgreSQL and Neo4j, fuses results, and returns a confidence score. Higher confidence means more cross-source corroboration — the system is honest about what it knows well versus what it knows less about.

Confidence correlates with cross-source matches. Queries hitting both stores score highest. This is designed behavior — the system quantifies its own certainty.

Self-Awareness: 100% Reliable

UNA can introspect her own architecture on demand. The get_self_model() function queries her knowledge graph for architecture descriptions and module metadata, returning a structured self-model.

Concurrent Load

Five parallel knowledge retrieval queries, three rounds. Tests whether the pipeline degrades under contention.

Self-Healing Recovery

The definitive test of autonomous infrastructure. We completely destroyed UNA's database container and watched her rebuild herself.

Cold-Start (container restart)

Kill-Recovery (total destruction → autonomous rebuild)

Container completely deleted with docker rm -f. No data. No container. Nothing. The Infrastructure Sovereign daemon detected the loss and rebuilt from its cryptographic manifest:

• t = 0s — Container Destroyed
  Complete removal. No container, no process, no mapped ports. Database gone.
• t = 45.3s — Sovereign Detects
  Health check cycle finds missing container. Reads manifest. Begins atomic rebuild.
• t = 53.4s — Full Health Restored
  Both ports mapped. Config volume mounted. HTTP API responding. 451 nodes intact. 11 architecture nodes verified.
• t = 53.6s — Pipeline Live
  First query returns 0.950 confidence, 8 cross-referenced sources. Full service restored.

How the Sovereign Works

The Infrastructure Sovereign is a single daemon process that replaces three conflicting legacy watchdogs. It operates on a simple principle: one manifest, one guardian, zero ambiguity.

Every 60 seconds, the Sovereign runs a deep health check: Docker running → container exists → ports mapped correctly → config volume mounted → HTTP API responding → Cypher execution working → architecture nodes present → config file verified. Any drift triggers an atomic recreate from the manifest — never a patch, always a clean rebuild.

The KnowledgeBridge pipeline also integrates a self-repair trigger: if any Neo4j query fails, it directly invokes the Sovereign's repair function, providing sub-cycle recovery for transient failures.

Test Environment

All benchmarks run on production data under normal system load. No isolated test environment. No warm-up runs excluded. What you see is what you get.

Live Evidence — Kill-Recovery Test

Executed March 20, 2026 at 23:47 PDT. Container forcibly destroyed, sovereign auto-detected and rebuilt from manifest. All timestamps from production logs.

Post-Recovery Pipeline Verification

Within seconds of recovery, the full KnowledgeBridge pipeline was queried to verify end-to-end functionality:

The sovereign logs a heartbeat every 10 minutes when healthy. Node count growth proves the graph is actively written to while the sovereign maintains health:
