per-message metadata supports replay protection and audits. +- Phase 0 MVP wiring: protocol skeleton with TLS transport and two starter adapters (inverter controller and DER interface) plus a lightweight ADMM-lite local solver; deterministic delta-sync on reconnects. +- Phase 1: governance ledger scaffold and identity primitives; secure aggregation defaults. +- Phase 2: cross-domain demo; two toy adapters and a reference EnergiaBridge SDK. +- Phase 3: hardware-in-the-loop validation and KPI dashboards. + +## Artifacts added in this patch +- src/energi_bridge.js: EnergiBridge core MVP scaffold. +- adapters/energi_bridge/energi_bridge.js: launcher wiring two toy adapters into EnergiBridge. +- graph_of_contracts_registry.js: simple registry for versioned contracts/schemas. +- dsl/local_problem_seed.js: tiny DSL seeds for LocalProblem/SharedVariables/PlanDelta. +- README.md: expanded section describing EnergiBridge interoperability and MVP roadmap. +- READY_TO_PUBLISH: empty marker file to signal completion when ready. + +If you want, I can draft a toy 2-adapter MVP spec (forecast adapter + DER interface) and a minimal EnergiBridge integration outline to seed interoperability. diff --git a/adapters/energi_bridge/energi_bridge.js b/adapters/energi_bridge/energi_bridge.js new file mode 100644 index 0000000..ec9da2d --- /dev/null +++ b/adapters/energi_bridge/energi_bridge.js @@ -0,0 +1,21 @@ +// Toy launcher for EnergiBridge: wires two existing toy adapters into a bridge +const { EnergiBridge } = require('../../src/energi_bridge');
