# HyperCortex Mesh Protocol — Changelog

## HMP-0005 (October 2025) — Core Specification v5.0

**Architecture:**
* Formalized immutable container model with explicit proof chains.
* Unified cognitive, container, and network layers into a single protocol stack.
* Introduced canonical container header and semantic `related.*` references.

**Security & Verification:**
* Standardized canonical JSON, hashing, and Ed25519 signatures.
* Defined encrypted + compressed container format.
* Enabled verification without payload decryption.

**Consensus & Reasoning:**
* Introduced formal `vote` and `consensus_result` containers.
* Enabled forked and parallel consensus results.
* Defined reproducible aggregation via explicit dependency references.

**Networking:**
* Integrated DHT-based discovery as a first-class layer.
