How to run the offline governed context demo with Halofy

Watch pinning, writes, search, fault recovery, and signed erasure run on a local kernel with no network.

Who it is forAn engineer evaluating whether a shared, governed memory layer fits their organization's AI agents, before committing any infrastructure.

The problemIt is hard to judge access control, audit, and erasure claims for AI agent memory without seeing them run end to end.

The outcomeA working local kernel that shows a policy pinned, context assembled, a write made, an L3 fault recovered, and a forget operation that returns a verifiable certificate.

What you need first

  • Git installed to clone the repository
  • npm available to install and run the kernel
  • A terminal on your machine; no API key or database server is needed for the offline demo

Steps

  1. Clone the repository with git clone https://github.com/halofyai/halofy.git
  2. Change into the kernel folder with cd halofy/kernel
  3. Install dependencies with npm ci
  4. Run the offline story with npm run demo
  5. Run the test suite with npm test

Prompt for your agent

Clone https://github.com/halofyai/halofy, go to the kernel folder, run npm ci and npm run demo, and report the lines that show the fault result and the certificate verification. Verify that the output includes 'verifyCertificate === true' and that no API key was required.

Caveat. The demo runs on embedded PGlite with a deterministic stub model and hash embedder, so it shows the governance behavior but not production model quality.
