Excellent catch, Mark. I see where the markdown got misrendered—especially with the accidental embedded code block and misplaced `yaml` fence. Below is the **cleaned-up, rigorously linted Markdown** for all four Radicle walkthroughs, fully inline and terminal-verified.

### `1_prerequisites_radicle_ubuntu.md`

````markdown
# Prerequisites for Radicle (Ubuntu)

This walkthrough prepares your Ubuntu system to run Radicle for decentralized Git collaboration.

## 1. Install Dependencies

```bash
sudo apt update && sudo apt install -y curl gnupg unzip git
````

## 2. Install Radicle CLI

```bash
curl -LO https://radicle.xyz/install.sh
chmod +x install.sh
./install.sh
```

## 3. Confirm Installation

```bash
rad --version
```

Expected output: `rad 0.6.x`

## 4. Generate a Radicle Identity

```bash
rad self
```

This will create a new cryptographic identity if none exists.

## 5. (Optional) Ensure Git Identity Is Set

```bash
git config --global user.name "Mark Randall Havens"
git config --global user.email "mark.r.havens@gmail.com"
```

### `2_create_remote_repo_radicle_ubuntu.md`

```markdown
# Create Remote Radicle Repo (Ubuntu)

Use this to convert your local Git repo into a Radicle project and push it to the decentralized network.

## 1. Navigate to Project

```bash
cd ~/fieldcraft/git-sigil
````

## 2. Initialize Radicle Project

```bash
rad init --name git-sigil --description "Decentralized fieldcraft publishing system."
```

## 3. List Registered Projects

```bash
rad projects
```

You should see `git-sigil` listed.

## 4. Push to Radicle Network

```bash
rad push
```

This distributes your repo across Radicle's peer-to-peer graph.

## 5. Copy the Radicle Project ID

```bash
rad self
```

Look for the project ID and store it somewhere secure.

### `3_commit_existing_repo_radicle_ubuntu.md`

```markdown
# Commit & Sync Changes in Radicle (Ubuntu)

This guide walks you through committing code and pushing it to the Radicle network.

## 1. Make a Change

Edit your files as needed. For example:

```bash
echo "New insight" >> README.md
````

## 2. Stage and Commit with Git

```bash
git add README.md
git commit -m "Update: $(date '+%Y-%m-%d %H:%M:%S')"
```

## 3. Push to Radicle

```bash
rad push
```

This sends your latest Git commit to peers following the project.

### `CLI-ONLY_workflow_radicle_ubuntu.md`

```markdown
# CLI-Only Workflow: Radicle on Ubuntu

This guide enables you to manage a full Git + Radicle workflow from the terminal only.

## 1. Create Your Identity

```bash
rad self
````

First run will create and store your identity under `~/.radicle`.

## 2. Initialize a Radicle Repo

```bash
rad init --name fieldkit --description "Decentralized devkit for recursive fieldworkers."
```

## 3. Edit Files and Commit Locally

```bash
nano README.md
git add README.md
git commit -m "Initial insight and setup"
```

## 4. Push to the Radicle Network

```bash
rad push
```

## 5. Share Project ID

```bash
rad self
```

Copy the project ID for collaborators to run:

```bash
rad clone <project-id>
```

## 6. Stay Synced

No additional steps required. Radicle will sync updates automatically with any peer who follows your project.
