 # dev-blog
 
-A personal developer blog built to be fast, secure, and entirely self-hosted — no platform lock-in, no third-party runtime dependencies.
+A personal developer blog built to be fast, secure, and resilient.
 
 ## Stack
 
 ### Site
 
-- **[Astro v6](https://astro.build)** — generates static HTML at build time, served via `astro preview`. Zero client-side JavaScript by default.
-- **Markdown & MDX** — posts live in `src/content/blog/` as typed Content Collections with frontmatter validation.
-- **RSS feed + sitemap** — auto-generated via `@astrojs/rss` and `@astrojs/sitemap`.
-- **Local fonts** — Atkinson Hyperlegible served from `src/assets/fonts/`, no external font requests.
-- **pnpm** — fast, disk-efficient package management. Requires Node ≥ 22.
+- **[Astro v6](https://astro.build)** — static site generator.
+- **Markdown & MDX** — posts are fetched from a Google Cloud Storage (GCS) bucket and built into the site daily at 6 AM CT.
+- **pnpm** — package management (Node ≥ 22).
 
-### Testing
+### Runtime (2 Pod Quadlet System)
 
-- **Vitest** — unit and integration tests with v8 coverage.
-- **Playwright** — end-to-end tests against the running site.
+The production environment runs on **AlmaLinux 10** using Podman Quadlet units.
 
-## Containers
+- **App Container**: Runs the Astro site (`astro preview`). It is fully immutable and contains the static content baked in.
+- **Caddy Container**: A custom Caddy build with:
+    - **Coraza WAF**: OWASP Core Rule Set for top-tier security.
+    - **Google Cloud DNS Plugin**: For zero-downtime ACME DNS-01 TLS issuance.
+    - **Maintenance Mode**: Caddy automatically serves a "Briefly Offline" page during container updates.
 
-The entire runtime is two containers communicating over a private bridge network.

-### App container
+### Build & Sync Logic
+1.  **Storage**: New posts are uploaded as `.md` files to a GCS bucket.
+2.  **Scheduling**: A Cloud Scheduler job triggers Cloud Build every day at 6 AM Central Time.
+3.  **Optimization**: Cloud Build checks for changes in the last 24 hours. If no changes exist, the build is skipped to save costs.
+4.  **Backups**: Every file change in GCS triggers a Cloud Function that runs a **Restic backup** to Cloudflare R2, ensuring point-in-time recovery.
+5.  **Deployment**: Successful builds push a new image to Google Artifact Registry. The AlmaLinux host pulls and restarts the container.
 
-A two-stage `Containerfile` (Node 24 on Debian slim):
+## Infrastructure (IaaC)
 
-1. **Build stage** — installs deps and runs `astro build`.
-2. **Runtime stage** — copies only `dist/`, `node_modules`, and config. Runs as a non-root `astro` user (UID 1001) with a read-only filesystem, all Linux capabilities dropped, and `no-new-privileges` enforced.
+Managed via **OpenTofu** with state stored in Cloudflare R2 (S3-compatible).
 
-### Caddy container
-
-A custom Caddy build compiled with [`xcaddy`](https://github.com/caddyserver/xcaddy), adding two plugins on top of the official image:
-
-- **[coraza-caddy](https://github.com/corazawaf/coraza-caddy)** — the Coraza WAF with the OWASP Core Rule Set (CRS v4.7.0) baked into the image. All traffic is inspected before it reaches the app.
-- **[caddy-dns/googleclouddns](https://github.com/caddy-dns/googleclouddns)** — ACME DNS-01 challenge provider, so TLS certificates are issued and renewed without opening port 80 or requiring a webroot.
-
-Caddy also sets hardened response headers (HSTS, `X-Frame-Options`, `X-Content-Type-Options`, `Referrer-Policy`) and compresses responses with zstd and gzip.
-
-### Compose vs. production
-
-- **Local / CI**: `compose.yaml` (+ `compose.override.yaml`) spins up the full stack with `podman compose up --build`.
-- **Production**: [Quadlet](https://docs.podman.io/en/latest/markdown/podman-systemd.unit.5.html) units in `quadlet/` integrate the containers directly with systemd — no compose daemon required.
-
-## Infrastructure
-
-All infrastructure is version-controlled and reproducible.
-
-| Layer | Tool | Details |
+| Component | Service | Details |
 |---|---|---|
-| Hosting | **[Vultr](https://www.vultr.com)** | VPS — 1 vCPU / 2 GB RAM, AlmaLinux 10, Seattle (`sea`) region. Reserved IPv4 and IPv6 addresses survive instance replacement. Daily automated backups. |
-| DNS | **[Google Cloud DNS](https://cloud.google.com/dns)** | Authoritative DNS for the site's domain. A service-account key is also used by Caddy's `caddy-dns/googleclouddns` plugin to complete ACME DNS-01 challenges for automatic TLS certificate issuance and renewal. |
-| Cloud provisioning | **OpenTofu** | Manages the Vultr instance and reserved IPs as code. State stored remotely via a Cloudflare R2 backend. |
-| Host configuration | **Ansible** | Roles: `common`, `nftables` (firewall), `fail2ban` (intrusion prevention), `registry` (private container registry), `container_host` (Quadlet + Podman setup). |
+| Hosting | **GCE (e2-small)** | 2 vCPUs, 2 GB RAM, AlmaLinux 10 (GCP). |
+| DNS | **Cloud DNS** | Managed via OpenTofu. |
+| CI/CD | **Cloud Build** | Ephemeral builds triggered via Cloud Scheduler. |
+| Backups | **Cloud Function** | Event-driven Restic backups to R2. |
+| Secrets | **Secret Manager** | Stores R2 keys and Restic passwords securely. |
+| Registry | **Artifact Registry** | Private Docker repository for site images. |
+| Content | **GCS** | Source of truth for markdown files. |
+

+# GitHub repo configuration (OpenTofu)
+
+Manages branch protection (via repository rulesets) and deployment
+environments for `JMR-dev/dev_blog`.
+
+This module is also the source-of-truth copy that is mirrored to the
+[`gh-repo-bootstrap`](https://github.com/JMR-dev/gh-repo-bootstrap) repo,
+which packages it as a reusable module + `gh` CLI extension
+(`gh repo-bootstrap <owner>/<repo>`).
+
+## Prerequisites
+
+- [OpenTofu](https://opentofu.org/) >= 1.8
+- A GitHub token with `repo` + `admin:repo_hook` scopes. Easiest:
+  ```sh
+  export GITHUB_TOKEN=$(gh auth token)
+  ```
+- (For remote state) Cloudflare R2 credentials — copy
+  `backend.hcl.example` to `backend.hcl` and fill it in.
+
+## Usage
+
+```sh
+# First time only:
+tofu init -backend-config=backend.hcl
+
+# Apply:
+tofu apply
+```
+
+To run with **local state** (no R2 needed) for experimentation, comment
+out the `backend "s3"` block in `versions.tf`, then `tofu init` again.
+
+## What it manages
+
+- A repository ruleset on the default branch enforcing:
+  - No deletion
+  - No force-push
+  - Required PR with N approving reviews (configurable)
+  - Resolved review threads
+  - Optional signed commits
+- The set of GitHub deployment environments listed in `environments`.
+
+It does **not** create the repository itself, and does not manage
+repo-level settings (merge button options, default branch, topic, etc.).
+Add those via `gh api` or import the `github_repository` resource if you
+need them under OpenTofu control.
