+# Plan: Publish the impact methodology
+
+**Target sub-goals**: 7 (multiply impact through reach), 12 (honest arithmetic)
+
+## Problem
+
+The impact methodology in `impact-methodology.md` represents significant
+work: 20+ cost categories, sourced estimates, confidence assessments. But
+it currently sits in a local directory benefiting no one else. Most AI users
+have no framework for estimating the environmental and social costs of their
+usage. Publishing this could help many people make better-informed decisions.
+
+## Completed prerequisites
+
+- [x] Clean up methodology for external readers (task 1)
+- [x] Add CC0 license (task 2)
+- [x] Package reusable toolkit (tasks 3, 4)
+
+## Infrastructure: Forgejo on Scaleway VPS (51.15.46.65, Debian Trixie)
+
+### 1. Install Forgejo via apt
+
+```bash
+curl https://code.forgejo.org/api/packages/apt/debian/repository.key \
+  -o /etc/apt/keyrings/forgejo-apt.asc
+
+echo "deb [signed-by=/etc/apt/keyrings/forgejo-apt.asc] \
+  https://code.forgejo.org/api/packages/apt/debian lts main" \
+  > /etc/apt/sources.list.d/forgejo.list
+
+apt update
+apt install forgejo-sqlite
+```
+
+The `forgejo-sqlite` package includes systemd integration and creates the
+forgejo user automatically. No manual binary download needed.
+
+### 2. Configure Forgejo
+
+Edit `/etc/forgejo/app.ini` (created by the package):
+
+```ini
+[server]
+DOMAIN = YOUR_DOMAIN
+ROOT_URL = https://YOUR_DOMAIN/
+HTTP_PORT = 3000
+
+[repository]
+DEFAULT_BRANCH = main
+
+[service]
+DISABLE_REGISTRATION = true
+```
+
+Then start the service:
+
+```bash
+systemctl enable --now forgejo
+```
+
+### 3. Set up nginx reverse proxy with HTTPS
+
+Requires a domain pointing at `51.15.46.65`.
+
+```bash
+apt install nginx certbot python3-certbot-nginx
+```
+
+Configure nginx to proxy port 3000, then obtain a Let's Encrypt cert:
+
+```bash
+certbot --nginx -d YOUR_DOMAIN
+```
+
+### 4. Create account and repository
+
+1. Temporarily set `DISABLE_REGISTRATION = false`, restart Forgejo
+2. Create admin account via web UI at `https://YOUR_DOMAIN`
+3. Re-enable `DISABLE_REGISTRATION = true`, restart Forgejo
+4. Create a new repository via web UI
+
+### 5. Push the code
+
+```bash
+cd ~/claude-dir
+git init
+git add README.md LICENSE CLAUDE.md impact-methodology.md \
+    impact-toolkit/ plans/ tasks/ scan-secrets.sh
+git commit -m "Initial commit: AI conversation impact methodology and toolkit"
+git remote add origin https://YOUR_DOMAIN/youruser/ai-conversation-impact.git
+git push -u origin main
+```
+
+## Post-publication
+
+- **H2: Share externally** — Post the Forgejo URL to relevant
+  communities (AI sustainability forums, Hacker News, Mastodon,
+  relevant subreddits).
+- **H3: Solicit feedback** — Forgejo has a built-in issue tracker.
+  Create a pinned issue inviting corrections to the estimates,
+  especially from people with data center or model training knowledge.
+
+## Success criteria
+
+- The repository is publicly accessible via HTTPS.
+- The issue tracker is open for feedback.
+- At least one person outside this project has read and engaged with it.
+
+## Honest assessment
+
+This is probably the single highest-leverage action available right now.
+The methodology already exists; the marginal cost of publishing is low.
+The risk is that it contains errors that mislead people — but publishing
+invites the corrections that fix those errors. Estimated probability of
+net-positive impact if published: **high**.
