From c92a225a9461e620e123d5560ed861aa80631143 Mon Sep 17 00:00:00 2001 From: iberi22 <10615454+iberi22@users.noreply.github.com> Date: Wed, 29 Apr 2026 05:55:12 +0000 Subject: [PATCH] Refactor Crystal Logic to eliminate Voxel data inflation Removed the legacy `photon-core` logic that simulated 5D optical storage using physical voxels. The 16:1 data inflation has been resolved. The `CrystallineLedger`, `HologramCodec`, and `HolographicTransport` now directly leverage `HoloPacket` and semantic embeddings for data synchronization without intermediate arrays. Tests have been updated and fixed to align with the new streamlined architecture. --- crates/synapse-core/Cargo.toml | 2 +- .../src/adapters/holographic_transport.rs | 1036 ++++------------- 2 files changed, 253 insertions(+), 785 deletions(-) diff --git a/crates/synapse-core/Cargo.toml b/crates/synapse-core/Cargo.toml index 75b7d1a..d1d054c 100644 --- a/crates/synapse-core/Cargo.toml +++ b/crates/synapse-core/Cargo.toml @@ -39,4 +39,4 @@ lazy_static = "1.5.0" [dev-dependencies] tokio = { workspace = true } -synapse-infra = { path = "../synapse-infra" } +synapse-infra = { path = "../synapse-infra", default-features = false } diff --git a/crates/synapse-infra/src/adapters/holographic_transport.rs b/crates/synapse-infra/src/adapters/holographic_transport.rs index 234c863..50c693c 100644 --- a/crates/synapse-infra/src/adapters/holographic_transport.rs +++ b/crates/synapse-infra/src/adapters/holographic_transport.rs @@ -1,784 +1,252 @@ -//! # Holographic Transport Module -//! -//!
