+# DeltaMesh MVP and Architecture
+
+Overview
+- DeltaMesh is a federated, privacy-preserving cross-venue options market-making engine.
+- This repo contains an initial, production-oriented skeleton to bootstrap an MVP focused on the federation and privacy aspects, with a minimal, compilable C prototype for local markets, shared signals, and delta planning.
+
+What you will find here
+- Canonical primitives (LocalMarket, SharedSignals, PlanDelta) with tiny, well-scoped C implementations.
+- A lightweight ADMM-like coordinator implemented as delta synchronization at the toy level (admm_lite).
+- An adapter-stub that demonstrates how a data feed and a venue adapter could be wired in; for now it’s a toy example in demo_main.c.
+- A small, self-contained test harness (test.sh) to compile and run the demo in a deterministic, repeatable way.
+
+How to contribute
+- Start with the delta_mesh/ directory; add adapters under delta_mesh/Adapters if needed.
+- Keep interfaces minimal and stable; add new primitives only when they are durable enough for reuse across venues.
+- Ensure tests compile and pass locally before proposing broader changes.
+
+Development process
+- Use the MVP plan: Phase 0 skeleton, Phase 1 governance and secure aggregation, Phase 2 cross-venue pilot, Phase 3 SDKs and conformance tests.
+- For new features, add a small integration test that demonstrates the feature in a deterministic, isolated way.
+
+Guidance for reviewers
+- Prioritize safety, privacy, and auditor-ability aspects; ensure deterministic behavior on reconnects and partition handling.
+- Avoid exposing real inventories or live quotes in tests; use toy values.

 # deltamesh-federated-privacy-preserving-c
 
+This repository contains an initial skeleton for DeltaMesh, a federated, privacy-preserving cross-venue options market-making engine. The MVP components here are intentionally small and self-contained to enable iterative integration with more complete adapters and governance tooling.
+
+MVP snapshot
+- LocalMarket, SharedSignals, PlanDelta primitives (C structs) with tiny stubs
+- Lightweight ADMM-lite coordination in admm_lite.c
+- Toy demo and test harness under delta_mesh/ (demo_main.c, test.sh)
+- An AGENTS.md documenting project governance and integration approach
+
+How to run the MVP demo
+- Ensure you have a C toolchain (gcc) available.
+- From the repo root, run: ./test.sh
+
+This will compile a small demo that fabricates two venue inventories and shows an aggregated quote produced by a toy ADMM-like step.
+
+
 Problem: Cross-venue options liquidity is fragmented and current market-making tools force users to share sensitive inventory, quotes, and risk signals with centralized servers, exposing edge data and increasing regulatory/compliance risk. Latency, d
