# Show HN: GGG – A local-first, zero-telemetry sovereign proxy daemon for AI tools > Source: > Published: 2026-09-19 03:09:11+00:00 **Garza Global Graviton LLC** builds sovereign, 100% air-gapped edge computing systems — hardware and software that run entirely on local infrastructure, with zero mandatory network dependency, zero cloud telemetry, and zero vendor-side visibility into your data. The node's local web hub ([`index.html`](https://github.com/JOxKxER/garza-global-graviton/blob/main/index.html)) is now fully mobile-responsive as of **v1.4.0**: brand bars, the hardware plaque, the physics benchmark table, and the local Ollama bridge all reflow cleanly on phones and tablets (screens under 768px), with buttons, inputs, and panels expanding to full width for comfortable touch interaction, and the physics benchmark table gaining smooth horizontal scrolling instead of a broken layout. Every node runs as a **Synthetic Data Center**: a single piece of local, air-gapped hardware organized like a living organism, paced and defended by cooperating biological daemons that never touch the network: - **Metabolic Heart** — paces admission and pulses the node's cadence at microsecond precision. - **Liver** — scrubs stale memory in-place with vectorized zeroization, never leaving residue. - **Lungs** — inhale and exhale data through a zero-copy ring buffer, moving bytes without ever duplicating them. - **Immune System** — a zero-trust scanner that quarantines and neutralizes any byte pattern it does not recognize. Because every buffer is a single preallocated `memoryview` over a `numpy` array, data moves through the organism without a single extra copy, and because the node is air-gapped, every daemon above runs at local hardware speed, not network speed. - **Local-only by construction.** The Ollama bridge only accepts`localhost` /`127.0.0.1` /`[::1]` endpoints; remote hosts are rejected before any request is ever sent, keeping the bridge 100% offline by construction. - **Sovereign data ownership.** Nothing leaves the device unless you explicitly choose to send it — there is no cloud dependency in the critical path. Grab the latest packaged sovereign app from the GitHub Releases page: ``` https://github.com/JOxKxER/garza-global-graviton/releases/latest ``` Or click **Download Sovereign App** directly from the top of the local web hub ([`index.html`](https://github.com/JOxKxER/garza-global-graviton/blob/main/index.html)). 1. Install and start [Ollama](https://ollama.com) on the same machine (or another host reachable at`localhost` /loopback). 2. Pull a model, e.g. `ollama pull llama3.2:3b` . 3. Open `index.html` in a browser and, in the**Local Ollama Bridge** panel, confirm the endpoint (default`http://localhost:11434` ) and model name, then click**Check Status** . 4. Once the badge shows **ONLINE** , use the**Live Local Benchmark** panel or the chat row to send prompts — everything runs locally, offline. The released `ggg-daemon.exe` is self-signed (no commercial code-signing certificate), so Windows SmartScreen will show **"Windows protected your PC"** on first launch. This is expected for unsigned local binaries — it is a reputation warning, not a detection. **To run it:** 1. On the SmartScreen dialog, click **"More info"** . 2. Click **"Run anyway"** — the choice is remembered for that file. **Verify authenticity before running** (recommended): every release ships a `SHA256SUMS.txt` alongside the binary. Compare the hash: ``` Get-FileHash .\ggg-daemon_v1.4.5_windows.zip -Algorithm SHA256 # Then compare against the matching line in SHA256SUMS.txt ``` If the hash matches the published manifest, the binary is exactly what this repository built. If it does not match, do not run it. Keep your editor 100% local by pointing a local-model extension at the same Ollama daemon (`http://localhost:11434`). Add to your VS Code `settings.json` (`Ctrl+Shift+P` → *Preferences: Open User Settings (JSON)*): ``` { "continue.server": { "port": 11434 }, "continue.models": [ { "title": "GGG Local Qwen", "provider": "ollama", "model": "qwen2.5-coder:latest", "apiBase": "http://localhost:11434" } ], "ollama.baseUrl": "http://localhost:11434", "localai.model.basePath": "http://localhost:11434" } ``` - **Continue.dev** (`Continue.continue` ): the`continue.models` entry selects your local`qwen2.5-coder` as the chat/edit model. See[.continue/config.json](https://github.com/JOxKxER/garza-global-graviton/blob/main/.continue/config.json) for this repo's ready-made Continue configuration. - **Ollama extensions** (e.g.`Ollama.ollama` ):`ollama.baseUrl` redirects all model calls to loopback. - **GitHub Copilot** does not support custom/local model providers — use Continue or an Ollama extension for fully offline AI assistance. Cryptographic proof, for prospective enterprise buyers, that a sensitive manufacturing/data pipeline ran in a strictly air-gapped, tamper-evident environment -- verifiable entirely offline, without ever seeing the vendor's proprietary pipeline source. All of this lives under [`airgap_attestation/`](https://github.com/JOxKxER/garza-global-graviton/blob/main/airgap_attestation). **Honesty note:** no software system can produce an unconditional *mathematical* proof of "zero network leakage" from a black box. What this platform delivers is a layered, tamper-evident, independently falsifiable evidence chain (hardware-rooted measurement + a cryptographically sealed execution log + dual signatures) where any single point of compromise is detectable. See [`airgap_attestation/CLIENT_ONBOARDING.md`](https://github.com/JOxKxER/garza-global-graviton/blob/main/airgap_attestation/CLIENT_ONBOARDING.md) for what a buyer should actually conclude from a passing/failing result. ``` CLIENT AIR-GAPPED EXECUTION ENCLAVE CLIENT | 1. commit-reveal blind | a.

The one large coverage gap (`attestation.py`, ~61%) is `Tpm2ToolsAttestor` -- the real-hardware TPM 2.0 code path, which is untestable without physical TPM hardware and is not mocked out just to inflate the number. See [`airgap_attestation/container/`](https://github.com/JOxKxER/garza-global-graviton/blob/main/airgap_attestation/container) and its `deployment_runbook.ps1`. Summary of the layered controls (any one being misconfigured must not compromise the others): | Control | Where | What it guarantees | |---|---|---| | `network_mode: none` | `docker-compose.yml` | No network namespace peer at all | | `network-interfaces: []` | `firecracker_config.json` | No NIC device exists for the guest (hypervisor-level, stronger than netns) | | `seccomp-hardened.json` | `docker-compose.yml` | Kernel-level deny of every network syscall, defense in depth under `--network none` | | `read_only` +`cap_drop: [ALL]` | `docker-compose.yml` | Immutable rootfs, no elevated capabilities | | `distroless nonroot` base image | `Dockerfile` | No shell, no package manager, uid 65532 | ``` # Render (see render.yaml): create a Blueprint instance pointing at this repo. # It provisions the web service + a 1GB persistent disk at /var/data for the # SubmissionStore's SQLite file, and generates AIRGAP_INTERNAL_INGEST_KEY for you. ``` Endpoints exposed by `nonce_service.py` (see [`CLIENT_ONBOARDING.md`](https://github.com/JOxKxER/garza-global-graviton/blob/main/airgap_attestation/CLIENT_ONBOARDING.md) for full request/response examples): | Method | Path | Caller | |---|---|---| | `POST` | `/v1/submissions` | Client -- issue a single-use nonce | | `GET` | `/v1/submissions/{id}` | Client -- poll status | | `GET` | `/v1/submissions/{id}/bundle` | Client -- download the sealed bundle | | `POST` | `/v1/internal/submissions/{id}/bundle` | Vendor's air-gapped runner export step only (key-protected) | | `GET` | `/healthz` | Load balancer / uptime check | Buyers should start at [`airgap_attestation/CLIENT_ONBOARDING.md`](https://github.com/JOxKxER/garza-global-graviton/blob/main/airgap_attestation/CLIENT_ONBOARDING.md), which walks through: generating a commit-reveal hash, requesting a nonce, delivering the sample out-of-band, polling for the bundle, and running ``` python airgap_attestation/cli/verify_cli.py \ --bundle AttestationBundle.json \ --platform-pubkey \ --nonce \ --ak-pubkey ``` Exit code `0` = passed, `1` = a real check failed (do not proceed with purchase), `2` = usage/file error. [`machine_boost_supervisor.py`](https://github.com/JOxKxER/garza-global-graviton/blob/main/machine_boost_supervisor.py) runs this machine's legitimate maintenance/health daemons on a schedule, with automatic restart for the long-running ones. [`machine_boost_service.py`](https://github.com/JOxKxER/garza-global-graviton/blob/main/machine_boost_service.py) wraps it as a native Windows service (via `pywin32`) so it starts at **boot**, not just at user logon. | Daemon | Mode | Interval | |---|---|---| | `watchdog_daemon.py` | one-shot, re-run | every 5 minutes | | `system_watchdog.py` | one-shot, re-run | every 5 minutes | | `snapshot_daemon.py` | one-shot, re-run | every 60 minutes | | `mesh_ping_daemon.py` | one-shot, re-run | every 1 minute | | `health_monitor.py` | persistent (self-looping) | started once, auto-restarted if it exits | **Deliberately excluded:** `traffic_daemon.py` and `live_cluster_daemon.py`. Both generate fake synthetic "client orders" tagged with real defense contractor names (Lockheed, DARPA, Raytheon, General Dynamics, Northrop) against a local API with a hardcoded key -- not a maintenance function, and not something that should run unattended at every machine startup fabricating usage data attributed to real companies. **Environment hardening applied to every managed child process:** | Variable | Why it's required | |---|---| | `PYTHONIOENCODING=utf-8` | Several daemons print emoji; without this they crash with `UnicodeEncodeError` the moment they run without a real console (exactly the situation under a Windows service). | | `PYTHONUTF8=1` | Belt-and-suspenders UTF-8 mode for the child interpreter. | | `PYTHONUNBUFFERED=1` | Piped stdout is fully block-buffered by default (not line-buffered); without this, `health_monitor.py` 's output can sit invisible in the child's buffer indefinitely instead of streaming to the log. | The supervisor's own `subprocess.run`/` Popen` calls also pass `encoding="utf-8"` explicitly -- `text=True` alone still decodes captured output using the OS locale (cp1252 on this machine) regardless of what the child's own encoding is set to, which silently reintroduces the same crash one layer up if omitted. All output is logged to `logs/machine_boost_supervisor.log` (git-ignored; it's runtime state, not source). ``` pip install -r requirements.txt # installs pywin32 among the rest python machine_boost_service.py install python machine_boost_service.py start ``` Check on it later: ``` Get-Service GGGMachineBoost Get-Content logs\machine_boost_supervisor.log -Tail 50 -Wait ``` Stop/remove it: ``` python machine_boost_service.py stop python machine_boost_service.py remove ``` [`ci.yml`](https://github.com/JOxKxER/garza-global-graviton/blob/main/.github/workflows/ci.yml) runs on every push/PR to `main`: Python 3.11, installs `requirements.txt`, runs the full test suite with coverage, and uploads the coverage report (`coverage.xml` + HTML) as a build artifact. ``` .\init_repo.ps1 # stage, commit, tag v1.0.0-release (no push) .\init_repo.ps1 -Push # also push the branch and tag to origin ``` This repository already has git history and an `origin` remote; the script detects that and only adds a new commit + tag for this milestone -- it does not reinitialize or rewrite existing history.
