# crdt-merge Data Playground

Tabular CRDT merge, conflict analysis, and core primitive demonstrations powered by [crdt-merge v0.9.5](https://github.com/mgillr/crdt-merge).

## Tabs

**Dataset Merge** — Loads glue/sst2 from HuggingFace datasets (or synthetic fallback). Merges two node partitions (150 + 100 records, 50 overlapping) with configurable strategy. Verifies commutativity: merge(A,B) == merge(B,A).

**E4 Trust Scoring** -- All merge operations carry typed trust scores (accuracy, consistency, recency, provenance) by default in v0.9.5+.

**Conflict Analysis** — Runs all four strategies (LWW, MaxWins, MinWins, Union) on the same dataset and computes per-field conflict rates between strategy pairs as a heatmap.

**Core CRDT Primitives** — Live demonstration of GCounter, PNCounter, LWWRegister, and ORSet. Each primitive is operated on two independent nodes then merged in both directions. Commutativity is verified for all four primitives.

## Installation

```
pip install crdt-merge>=0.9.5
