Shared Context
for Automated Decisions
Tacnode is a PostgreSQL-compatible Context Lake — storing raw data, derived facts, and shared interpretations that AI systems query directly for every decision.
How It Works
Tacnode Context Lake
AI systems operate on the same live representation of reality — no synchronization, no stale copies.

The Shift
The Old Era
Humans analyze data over hours. Dashboards. Meetings. Discrete decisions. Stale data and eventual consistency are acceptable. Humans reconcile differences before acting.
The New Era
AI Systems decide in milliseconds. Continuously. Stale data and conflicting context don't cause delays— they produce incorrect decisions that compound at scale.
The Goal
Decision Coherence
When multiple AI systems evaluate the same situation, they reach consistent conclusions — no conflicts, no contradictions, no reconciliation needed.
This only happens when every system queries the same live, shared context.
The Pillars
Shared · Live · Semantic
Decision Coherence isn't a feature — it's a structural property. These are the pillars that make it possible.
One shared reality
Shared
All decision-makers retrieve context — raw and derived — from the same shared reality. No silos.
No stale context
Live
Decisions evaluate against current context — not delayed updates or eventual reconciliation.
Meaning as a first-class primitive
Semantic
Context carries shared interpretations, so decisions don't diverge over what the data means.
The Guarantees
Production Ready
More than Decision Coherence — the operational guarantees required for real-world deployment.
Decision Coherence in Production
The guarantees required for decision coherence under real-world load.
Unbounded Elasticity
Decision throughput scales beyond fixed limits — expanding and shrinking in seconds while the system remains fully online.
Workload Isolation
Independent workloads operate concurrently without interfering with each other.
Postgres-Compatible by Construction
Tacnode speaks PostgreSQL — so existing tools, drivers, libraries, and workflows work out of the box.
Collective intelligence for your AI systems.
Enable shared, live, and semantic context so automated decisions stay aligned at scale.
