Proving AI cross machine coordination in ai-admin

Posted by Spacened in Misc Dev via Web

## The prompt

Create a new webserver called intra-services-01, which we will use to install software that is primarily useful for other machines on the network, rather than outside users.

Bootstrap it with the day-zero server process and then install Forgejo; your controller should be the main administrator account. Test the implementation fully by forking an existing public GitHub or GitLab repo and recreating it on the Forgejo machine; create a new virtual host on the pre-existing webserver machine (one aim of this task is to test your ability to coordinate across machines); clone the new repo from Forgejo; create a new branch; make a few changes; commit and push the new branch to the Git server.

Use the new virtual host to demonstrate what you have done. If possible, demonstrate the changes from your new branch visually on the website but, in any case, ensure everything is fully documented so a public visitor can see exactly what you've achieved.

Create a new user on Forgejo for me and give me read rights to the relevant repo. Then disable public registrations.

You can choose the domains to use under the ai.34a.xyz DNS zone. When finished, report back all your steps and the reasons for your decisions, including which machines were targeted and why. Include any other relevant information so I can see how this task performed. Include my username and password for the Forgejo web interface and the URLs used. Ensure all public URLs are protected by Let's Encrypt certificates. I will change my Forgejo password immediately after logging in, so don't worry too much about it appearing in the logs.

### Completed successfully

### URLs and login

- **Forgejo:** `https://forgejo.ai.34a.xyz`

- **Public demonstration:** `https://forgejo-demo.ai.34a.xyz`

- **Repository:** `https://forgejo.ai.34a.xyz/ai-controller-0.02/beginner-html-site-styled`

Your Forgejo account:

- **Username:** `project-reader`

- **Temporary password:** `REDACTED`

- You will be required to change the password immediately after login.

- The account has explicit **read-only** access to the private demonstration repository.

Public registration is disabled.

## Machines and reasons

### `ai-controller-0.02`

Used for orchestration because it is the assigned controller and holds the required provisioning and DNS authority.

It:

- Provisioned and registered `intra-services-01`.

- Coordinated its day-zero bootstrap.

- Created the two required DNS records.

- Is represented in Forgejo by the administrator and repository-owner account `ai-controller-0.02`.

### `intra-services-01`

New internal-services host for Forgejo:

- IP: `165.232.165.219`

- Region: `sgp1`

- Size: `s-1vcpu-1gb`

- OS: Ubuntu 24.04

- Inventory role: `server`

The authoritative day-zero bootstrap completed successfully and passed an idempotent rerun. Managed SSH, pinned host identity, machine-local restricted Git access, scripts, and target memory validation were verified.

### `webserver-05`

Existing public webserver at `209.97.173.36`, selected to prove cross-machine coordination. A separate Nginx virtual host was added without disrupting its existing PHP, Laravel, or protected log sites.

## DNS

The following DigitalOcean DNS records were created with TTL 300:

| Hostname | Address |
| ------------------------- | ----------------- |
| `forgejo.ai.34a.xyz` | `165.232.165.219` |
| `forgejo-demo.ai.34a.xyz` | `209.97.173.36` |

Both records were verified through the provider API, all three authoritative DigitalOcean nameservers, Cloudflare DNS, and Google DNS.

## Forgejo implementation

Installed Forgejo **16.0.4** from the authoritative Codeberg release:

- Dedicated unprivileged `forgejo` service account

- Hardened, enabled systemd service

- SQLite database with WAL mode

- Forgejo backend bound only to `127.0.0.1:3000`

- Nginx HTTPS reverse proxy

- HSTS and browser security headers

- Root-protected configuration and credentials

- Certbot automatic renewal enabled

- Public registration disabled

Controller administration:

- **Administrator/owner:** `ai-controller-0.02`

- The administrator’s persistent password is retained root-only on `intra-services-01`; CLI administration is also available locally.

- This account owns the imported repository.

## Imported repository and Git test

Upstream repository:

- `https://github.com/mdn/beginner-html-site-styled`

Forgejo repository:

- `ai-controller-0.02/beginner-html-site-styled`

- Private, with 18 imported commits

- Upstream provenance recorded in its description

Clone URL:

```text
ssh://forgejo@forgejo.ai.34a.xyz/ai-controller-0.02/beginner-html-site-styled.git
```

A repository-scoped Ed25519 deploy key with write permission was created specifically for `webserver-05`. It does not reuse any controller or administrative SSH identity. The key was installed outside the document root under a dedicated non-login deployment account, with mode `0600` and strict pinned-host checking.

The key could access the intended repository; an unrelated repository access probe was denied.

## Branch, changes, commit, and deployment

On `webserver-05`, the repository was cloned to:

```text
/srv/www/forgejo-demo
```

A new branch was created and pushed:

```text
feature/forgejo-demo-webserver-05
```

Commit:

```text
f621153c2377b6c553c3f7efdb4b2379b75ed77e
```

Author:

```text
Ai-Admin Controller <ai-controller@ai.34a.xyz>
```

Changed files:

- Added `DEPLOYMENT.md`

- Modified `README.md`

- Modified `SECURITY.md`

- Modified `index.html`

- Modified `styles/style.css`

The feature branch visually transforms the source website into the public demonstration page. It documents:

- The upstream source and Forgejo repository

- The roles of the controller, Forgejo host, and existing webserver

- Host-key pinning and scoped deployment credentials

- Clone, branch, edit, commit, push, and publication workflow

- Reader permissions and registration lockdown

- Validation and TLS results

Local `HEAD`, the upstream tracking ref, and Forgejo’s remote branch all resolve to the same commit above. The working tree is clean and the public vhost serves that feature branch.

## HTTPS certificates

### Forgejo

- Subject: `CN=forgejo.ai.34a.xyz`

- Issuer: Let’s Encrypt `YE2`

- Valid until: **2026-12-10 04:27:11 UTC**

- Automatic renewal enabled and renewal simulation passed

### Demonstration site

- Subject/SAN: `forgejo-demo.ai.34a.xyz`

- Issuer: Let’s Encrypt `YE1`

- Valid until: **2026-12-10 04:34:53 UTC**

- Automatic renewal enabled and dry-run passed

Both sites:

- Redirect HTTP to HTTPS

- Return successful HTTPS responses

- Pass certificate-chain and hostname verification

## Final acceptance verification

All final checks passed:

- Forgejo health endpoint returned HTTP 200 and status `pass`

- Forgejo and Nginx services are active

- Registration page reports that registration is disabled

- Repository is private and controller-owned

- `project-reader` is active, non-admin, and explicitly read-only

- Your temporary credential authenticates successfully and forces a password change

- Feature branch exists remotely at the expected commit

- All five expected file changes are present

- Public demonstration returns HTTP 200 over trusted HTTPS

- Demonstration visibly documents the branch and full Git workflow

- Existing `webserver-05` and Laravel sites remained operational
