feat(scripts): add tag_release.py — guided signed release tagger

Interactive script for maintainers to create GPG-signed annotated tags. Checks clean tree and branch, auto-increments version from latest tag, pulls the message from the matching changelog entry, resolves the release signing key (default: 9FA5436D0EE360985157382517ECA05F768DEDF6), creates the tag, verifies the signature, then prints the push command. Usage: python scripts/tag_release.py # auto version python scripts/tag_release.py --version v1.2.4 python scripts/tag_release.py --dry-run # preview only Signed-off-by: nopeitsnothing <no@anonymousplanet.org>

-# Changelog
-
-All notable changes to this project will be documented in this file.
-
-The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
-and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
-
-## [Unreleased]
-
-## [1.2.1] - 2026-04-11
-
-### Added
-
- GitHub Actions workflow **Build guide PDF** (`.github/workflows/build-pdf.yml`): installs Chromium on `ubuntu-latest`, runs `scripts/build_guide_pdf.py`, uploads `export/guide.pdf` as the `guide-pdf` artifact. Runs on `workflow_dispatch`, on pushes to `main` that touch docs or build inputs, and on matching pull requests.
-
- `scripts/build_guide_pdf.py` to build the MkDocs site and render the guide to a single PDF (`export/guide.pdf` by default) using a Chromium-based browser (Chrome or Edge) headless print-to-PDF.
- `docs/stylesheets/extra.css` and `extra_css` in `mkdocs.yml` for shared site styling.
- This `CHANGELOG.md`.
-
-### Changed
-
- `README.md` “Ways to read or export the guide”: hosted link, local `mkdocs serve`, PDF build via the script, ODT note, raw Markdown link.
- Guide landing layout: wrap the opening block in `docs/guide/index.md` with a `guide-intro-lead` container so the logo and first sections share one layout context for web and print.
- `.gitignore` to exclude local build outputs `export/`, `site/`, and `_site_test/`.
- `scripts/build_guide_pdf.py`: when the `CI` environment variable is set, pass Chromium flags (`--no-sandbox`, `--disable-setuid-sandbox`, `--disable-dev-shm-usage`) so headless print works on typical CI images.
- `README.md`: note the **Build guide PDF** GitHub Actions workflow and the `guide-pdf` artifact.
-
-### Fixed
-
- `docs/guide/index.md`: replace broken reference-style internal links (`[label][label:]`) with working same-page fragment links to the correct headings; correct the mismatched “Real-Name System” cross-reference; fix a broken footnote marker on the “free (unallocated) space of your hard drive” list item.

 - **Local HTML preview:** from the repository root, with Python 3 and [MkDocs Material](https://squidfunk.github.io/mkdocs-material/getting-started/) installed (`pip install mkdocs-material`), run `mkdocs serve` and open the URL printed in the terminal (for example `http://127.0.0.1:8000`).
- **PDF (local build):** from the repository root, using the same environment, run:
-
-  ```bash
-  python scripts/build_guide_pdf.py
-  ```
-
-  This runs `mkdocs build` (output defaults to `./site`), then uses **Google Chrome** or **Microsoft Edge** in headless mode to print `site/guide/index.html` to **`export/guide.pdf`** (images and styling preserved). If the site is already built: `python scripts/build_guide_pdf.py --skip-mkdocs`. Other options: `--site-dir`, `--pdf`, and `python scripts/build_guide_pdf.py --help`.
-
-  On **GitHub Actions**, the [Build guide PDF](https://github.com/Anon-Planet/thgtoa/actions/workflows/build-pdf.yml) workflow does the same using Chromium on Ubuntu when you push to `main` or open a pull request that touches the guide or build inputs; download the **`guide-pdf`** artifact from a successful run.

+# Release Notes
+
+Notable changes to the guide and its tooling. Follows [Keep a Changelog](https://keepachangelog.com/en/1.1.0/) and [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+---
+
+## [v1.2.3] — 2026-05-22
+
+CI/CD pipeline split into independent stages, dark PDF quality improved, and the changelog is now updated automatically on every release. v1.2.2 was just a placeholder, this is a minor but CI breaking change.
+
+!!! success "Added"
+
+    - **Dark mode PDF** (`scripts/convert.py`): pixel-level converter replaces the broken `--prefers-color-scheme=dark` Chromium flag. Produces a 200 DPI hacker-themed PDF (`#1f1f31` background, `#e0e0e0` text, `#5e8bde` links) with batched page processing to avoid OOM.
+    - **Three independent CI workflows** replacing the old monolithic `build-sign-release.yml`:
+        - `build.yml` — builds PDFs and uploads them as an artifact; no secrets required.
+        - `sign.yml` — downloads the PDF artifact, computes SHA-256 and BLAKE2b hashes, GPG-signs all outputs, and uploads a `signatures` artifact. Can be re-run against any historical build.
+        - `release.yml` — downloads both artifacts, uploads to VirusTotal, and publishes a tagged GitHub Release with all 12 assets attached. **Can be triggered manually against any previous sign run**.
+    - **`scripts/update_changelog.py`**: reads `git log` since the last version tag, categorises commits by conventional-commit prefix, and prepends a new entry here automatically after each successful build.
+    - **`changelog.yml`** workflow: commits the auto-generated changelog entry back to `main` after every build, with `dry_run` and `manual_version` dispatch inputs for testing.
+
+!!! warning "Changed"
+
+    - `build-sign-release.yml` is now deprecated — push triggers removed, manual dispatch only. Will be deleted once in-flight runs complete.
+    - The full pipeline (build → sign → release) now chains automatically via `workflow_run` on every push to `main`.
+    - GPG signing uses `--pinentry-mode loopback` and `--passphrase-fd 0` to avoid interactive prompts on headless runners.
+    - VirusTotal scans moved to the release stage so they run once per release, not once per build.
+
+!!! bug "Fixed"
+
+    - Broken internal links and a mismatched cross-reference in `docs/about/index.md`.
+    - Deprecated ODT section commented out in Appendix A6 of the guide.
+
+---
+
+## [v1.2.1] — 2025
+
+First automated PDF build and the start of the CI pipeline.
+
+!!! success "Added"
+
+    - `scripts/build_guide_pdf.py`: builds the MkDocs site and renders the full guide to a single PDF via headless Chromium (Chrome or Edge). Supports `--dark`, `--light`, and `--both` modes.
+    - GitHub Actions workflow that installs Chromium, runs the build script, and uploads `export/thgtoa.pdf` as an artifact on every push to `main` or manual dispatch.
+    - `docs/stylesheets/extra.css` for shared site styling.
+    - This changelog.
+
+!!! warning "Changed"
+
+    - `README.md` updated with instructions for local PDF export and a note about the GitHub Actions artifact.
+    - `.gitignore` updated to exclude local build outputs (`export/`, `site/`, `_site_test/`).
+
+!!! bug "Fixed"
+
+    - Broken reference-style internal links throughout `docs/guide/index.md` replaced with correct fragment links.
+    - Broken footnote marker on the "free (unallocated) space" list item in the guide.

+# Development
+
+??? Note "How the pipeline works"
+
+    **Automatic PDF Generation:** - Builds both light and dark mode PDFs from MkDocs source
+    **SHA256 Hash Generation:** - Creates hash files for integrity verification
+    **GPG Signature Signing:** - Signs all PDFs and hash files with repository GPG key
+    **VirusTotal Scanning:** - Automatically scans PDFs and updates release notes
+    **Release Automation:** - Packages everything into GitHub releases
+
+## Architecture
+
+### Build PDF Workflow (`build-sign-release.yml`)
+
+!!! Note "Steps"
+
+    - Checkout repository
+    - Set up Python and MkDocs Material
+    - Install Chromium browser
+    - Generate both light and dark mode PDFs with `scripts\build_guide_pdf.py`
+    - Create SHA256 and blake2 hash files in `export/`
+    - Sign all files with GPG in `export/`
+    - Upload artifacts to GitHub Actions **manually**
+
+### SHA256 Hash Verification
+
+!!! Note "**How it works**"
+
+    - Each PDF gets a unique SHA256 hash calculated at build time
+    - Hash stored in `.sha256` files alongside the PDFs
+    - Combined `sha256sum.txt` for batch verification
+
+### GPG Signature Verification
+
+**Purpose:** Verify authenticity and prevent tampering
+
+!!! Note "How it works"
+
+    - Detached signatures created for each PDF and hash file
+    - Public keys available in `/pgp/` directory
+
+**Verification command:**
+```bash
+gpg --import pgp/anonymousplanet-master.asc
+gpg --verify export/thgtoa.pdf.sig export/thgtoa.pdf
+```
+
+---
+
+*This workflow is designed for security-conscious users who need to verify the authenticity and integrity of downloaded documents.*

+description: How to verify the authenticity of our files and check virus scans
+---
+
+# PDF Verification Guide
+
+## Files Provided
+
+For each PDF release, you'll receive:
+
+- **PDF file** (`thgtoa.pdf` or `thgtoa-dark.pdf`) - The actual document
+- **Signature file** (`.sig`) - GPG detached signature for authenticity verification
+- **Hash file** (`.sha256`) - SHA256 checksum for integrity verification
+
+## Quick Verification
+
+### Using Python Script (Recommended)
+
+```bash
+# Verify everything (hashes, signatures, and optionally VirusTotal)
+python scripts/verify_pdf.py --all
+
+# Only verify hashes
+python scripts/verify_pdf.py --hashes
+
+# Only verify GPG signatures
+python scripts/verify_pdf.py --signatures
+
+# Check VirusTotal scan status (requires VT_API_KEY environment variable)
+python scripts/verify_pdf.py --vt
+```
+
+### Manual Verification
+
+#### 1. Verify SHA256 Hash
+
+**Linux/macOS:**
+```bash
+cd /path/to/repo
+sha256sum -c sha256sum-light.txt
+```
+
+**Windows (PowerShell):**
+```powershell
+Get-FileHash -Algorithm SHA256 export\thgtoa.pdf | Select-Object Hash
+# Compare with the hash in thgtoa.pdf.sha256
+```
+
+#### 2. Verify GPG Signature
+
+First, import the public key:
+```bash
+gpg --import pgp/anonymousplanet-master.asc
+```
+
+Then verify the signature:
+```bash
+gpg --verify export/thgtoa.pdf.sig export/thgtoa.pdf
+gpg --verify export/thgtoa-dark.pdf.sig export/thgtoa-dark.pdf
+```
+
+Expected output for successful verification:
+```
+gpg: Signature made Mon 20 Apr 2026 01:46:40 AM EDT
+gpg:                using EDDSA key 9FA5436D0EE360985157382517ECA05F768DEDF6
+gpg: Good signature from "Anonymous Planet Master Signing Key" [unknown]
+gpg: WARNING: This key is not certified with a trusted signature!
+gpg:          There is no indication that the signature belongs to the owner.
+Primary key fingerprint: 9FA5 436D 0EE3 6098 5157  3825 17EC A05F 768D EDF6
+```
+
+#### 3. Check VirusTotal Status
+
+Visit the VirusTotal report links (automatically generated in release notes):
+- Light mode: `https://www.virustotal.com/gui/file/[hash]`
+- Dark mode: `https://www.virustotal.com/gui/file/[hash]`
+
+Or use the Python script with API key:
+```bash
+export VT_API_KEY=your_vt_api_key
+python scripts/verify_pdf.py --vt
+```
+
+## Automated Verification in CI/CD
+
+The GitHub Actions workflows automatically:
+
+1. **Build PDFs** from MkDocs source
+2. **Generate SHA256 hashes** and save to root directory
+3. **Sign files with GPG** using the repository's private key
+4. **Scan with VirusTotal** and update release notes
+5. **Create releases** with all verification artifacts
+
+## Security Best Practices
+
+1. **Always verify signatures** before opening PDFs from untrusted sources
+2. **Check hashes** to ensure files weren't corrupted during download
+3. **Review VirusTotal results** for any suspicious detections
+4. **Import keys securely** - verify key fingerprints with the project maintainers
+5. **Keep verification scripts updated** to match current security standards
+
+## Troubleshooting
+
+### "Good signature" but wrong owner?
+- Ensure you imported the correct public key
+- Check the key fingerprint matches the official one from the repository
+
+### Hash mismatch?
+- Re-download the file (corruption during transfer)
+- Verify you're checking against the correct hash file
+- Check for disk errors on your system
+
+### GPG not found?
+- Install GPG: `sudo apt install gnupg` (Debian/Ubuntu) or `brew install gnupg` (macOS)
+- On Windows, use [Gpg4win](https://www.gpg4win.org/)
+
+## Key Information
+
+**Signing Key:** Anonymous Planet Master Signing Key ("MSK")
+**Key ID:** See `pgp/anonymousplanet-master.asc` for details
+**Fingerprint:** Verify from the repository's official documentation

+#!/usr/bin/env python3
+"""Release tagging helper for Anonymous Planet maintainers.
+
+Creates a GPG-signed annotated git tag using the release key, with a
+message derived from the changelog entry for that version.
+
+Usage:
+  python scripts/tag_release.py                  # auto-detect next version
+  python scripts/tag_release.py --version v1.2.4
+  python scripts/tag_release.py --version v1.2.4 --key <fingerprint>
+  python scripts/tag_release.py --version v1.2.4 --dry-run
+
+What it does:
+  1. Checks the working tree is clean and the branch is main
+  2. Resolves the version (auto-increments patch if not given)
+  3. Finds the matching ## [vX.Y.Z] entry in the changelog
+  4. Lists available signing keys and selects the release key
+  5. Creates a signed annotated tag: git tag -s vX.Y.Z -u <key> -m <message>
+  6. Verifies the tag signature
+  7. Prints the push command
+
+Requirements:
+  - git
+  - GPG with the release signing key imported

nopeitsnothing	cdc54d8b3b	feat(scripts): add tag_release.py — guided signed release tagger Interactive script for maintainers to create GPG-signed annotated tags. Checks clean tree and branch, auto-increments version from latest tag, pulls the message from the matching changelog entry, resolves the release signing key (default: 9FA5436D0EE360985157382517ECA05F768DEDF6), creates the tag, verifies the signature, then prints the push command.

nopeitsnothing	823edbf4af	fix(ci): resolve Pillow JPEG KeyError and cairosvg missing dep convert.py: Pillow's PDF writer requires libjpeg for RGB images, which is not available in the CI Python environment. Replace all Pillow PDF saves with _save_images_as_pdf(), which writes pages as lossless PNGs and assembles them with qpdf — no JPEG dependency needed. build.yml: install mkdocs-material[imaging] instead of mkdocs-material to satisfy the cairosvg dependency required by the social plugin.
