PAXECT Core Complete

Status: v1.0.0 — Initial Public Release — October 22, 2025

The curated PAXECT bundle: Core + AEAD Hybrid + Polyglot + SelfTune + Link — with 10 integrated demos, observability, and deterministic performance across OSes.

What it is: the official reference implementation of the PAXECT ecosystem — a verified, reproducible, cross-OS runtime that showcases the multi-OS bridge and in-freq multi-channel architecture in real workflows.

• Unified Ecosystem: Core + AEAD + SelfTune + Polyglot + Link in one deterministic bundle
• Reproducibility: bit-identical behavior across Linux, macOS, Windows (best-effort: BSD, mobile shells)
• Offline-first: zero telemetry, no network dependencies
• Enterprise-ready: 10 reproducible demo pipelines, audit trail, and metrics endpoints
• Zero-AI Runtime: SelfTune provides adaptive guardrails without ML or heuristics (no cloud)

Relationship

• PAXECT Core is a stand-alone OS-level deterministic bridge (plugin-capable).
• PAXECT Core Complete is the curated bundle that includes Core plus the official plugins and demo suite.
  Use Core when you want a minimal, plug-and-play bridge.
  Use Core Complete when you want the full experience (plugins + demos) out of the box.

Installation

Requirements

• Python 3.9 – 3.12 (recommended 3.11+)
• Works on Linux, macOS, Windows, FreeBSD, OpenBSD, Android (Termux), and iOS (Pyto).
• No external dependencies or internet connection required — fully offline-first runtime.

Optional Utilities

Some demos use these standard tools if available:

• bash (for demo_05_link_smoke.sh)
• dos2unix (for normalizing line endings)
• jq (for formatting JSON output)

Install

git clone https://github.com/PAXECT-Interface/paxect-core-complete.git
cd paxect-core-complete
python3 -m venv venv
source venv/bin/activate      # on Windows: venv\Scripts\activate
pip install -e .

Verify the deterministic core import:

python3 -c "import paxect_core; print('PAXECT Core OK')"

Then run any of the integrated demos from the demos/ folder to validate deterministic reproducibility.

Plugins (Official)

Plugin	Scope	Highlights	Repo
Core	Deterministic data container	.freq v42 · multi-channel · CRC32 + SHA-256 · cross-OS · offline-first	paxect-core-plugin
AEAD Hybrid	Encryption & Integrity	Hybrid AES-GCM / ChaCha20-Poly1305 — fast, zero dependencies, cross-platform	paxect-aead-hybrid-plugin
Polyglot	Multi-language bridge	Python · Node.js · Go — deterministic pipeline parity	paxect-polyglot-plugin
SelfTune 5-in-1	Runtime control & observability	Guardrails, backpressure, overhead limits, metrics, and jitter smoothing	paxect-selftune-plugin
Link (Inbox/Outbox Bridge)	Cross-OS file exchange	Shared-folder relay: auto-encode/decode .freq containers deterministically	paxect-link-plugin

Plug-and-play: Core operates standalone, with optional plugins attachable via flags or config. Deterministic behavior remains identical across environments.

🧪 Demo Suite (01 – 10)

Run reproducible demos from the repository root:

python3 demos/demo_01_quick_start.py
python3 demos/demo_02_integration_loop.py
python3 demos/demo_03_safety_throttle.py
python3 demos/demo_04_metrics_health.py
bash    demos/demo_05_link_smoke.sh
python3 demos/demo_06_polyglot_bridge.py
python3 demos/demo_07_selftune_adaptive.py
python3 demos/demo_08_secure_multichannel_aead_hybrid.py
python3 demos/demo_09_enterprise_all_in_one.py
python3 demos/demo_10_enterprise_stability_faults.py

All demos generate structured JSON audit logs under /tmp/, verifiable through deterministic SHA-256 outputs.

---

Testing & Verification

Internal pytest suites validate core reproducibility. End-users can rely on the integrated demo suite (01–10) for deterministic verification. Each demo reports performance, checksum validation, and exit status cleanly.
