APIs changed between libjpeg versions, so each version directory
needs its matching headers:
- 6b gets 6b headers
- 7 gets 7 headers
- 8-8d get 8d headers
- 9-9f get 9f headers

The setup.py has broken include_dirs that reference 'jpeglib/cjpeglib'
but the source files are in 'src/jpeglib/cjpeglib'. Create a symlink
to fix the include path resolution.

The PyPI source tarball is missing both jpeglib's own headers
(cjpeglib_common.h, etc.) and libjpeg headers. Clone from GitHub
which has the jpeglib headers, then download libjpeg headers.

jpeglib has no pre-built ARM64 wheel and the source tarball is missing
libjpeg header files. This adds a workaround that downloads the official
libjpeg headers before building.
- Add rpi/patches/jpeglib/install-jpeglib-arm64.sh helper script
- Update setup.sh to download headers when building from source
- Downloads headers for libjpeg 6b, 7-9f, turbo, and mozjpeg versions

- Rewrite setup.sh to use system Python instead of pyenv
- Add Python version check (3.11-3.14 supported)
- Remove jpegio build steps (jpeglib installs cleanly via pip)
- Simplify prebuilt tarball (just venv, no pyenv)
- Reduce install time: 5-10 min from source (was 15-20 min)
- Update README.md and BUILD_IMAGE.md accordingly

- Default branch: 4.1 → 4.2
- Update prebuilt URL to v4.2.0
- Update example filenames to 4.2.0
- Remove jpegio references (now using jpeglib)

Run on Pi after from-source build to create:
stegasoo-rpi-runtime-env-arm64.tar.zst (~50-60MB)

- Remove pv (showed read progress, not write progress)
- Use dd status=progress for actual write progress
- Reduce block size to 1M (better for slow SD cards)
- Remove conv=fsync (sync at end instead, faster)

Run fsck.vfat on boot partition and e2fsck on root partition
after flashing to catch and fix any corruption.

resize2fs only fills the partition. Need growpart first to
expand the partition to fill the disk, then resize2fs to
expand the filesystem.

Instead of a hidden systemd service, expand the filesystem
visibly during the first-boot wizard so users can see it
happening.

rpi-imager was doing something that prevented the auto-expand
service from working. Simplify to just dd with optional pv
for progress.

Move the partition wipe to after user types 'yes' so they can
still abort without having already wiped the device.

Create a systemd oneshot service that expands the rootfs on first boot
after flashing. The service self-destructs after running.
This ensures release images fill the SD card while keeping the
download size small (16GB shrunk image).
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
The shrinking is only for faster image downloads. After flashing,
the image should auto-expand to fill the SD card.

- Remove --compress/--algorithm CLI options (not wired to encode flow)
- Add man page installation to rpi/setup.sh
- Document man page installation in README.md and CLI.md
- Update man page to remove compression options
Compression will be properly implemented in v4.1.8.

Channel keys saved to config files are now encrypted using the
machine's identity (/etc/machine-id), so:
- Not stored in plaintext
- Tied to specific machine (can't copy file to another device)
- Legacy plaintext keys still work (auto-detected)
Changes:
- Added _encrypt_for_storage() and _decrypt_from_storage()
- set_channel_key() now encrypts before writing
- get_channel_key() decrypts when reading (handles legacy plaintext)
- Pi setup saves encrypted key to ~/.stegasoo/channel.key
- CLI `stegasoo info` now shows channel status correctly

No more browser warnings! mkcert creates locally-trusted certs.
Pi Setup:
- Auto-install mkcert during setup
- Generate trusted certs when HTTPS enabled
- Copy CA to /static/ca/rootCA.pem for easy device setup
- New devices can download CA via HTTP and install it
Docker:
- docker-entrypoint.sh checks for mkcert, falls back to openssl
- Shows instructions for CA distribution to other devices
Scripts:
- Added setup-trusted-certs.sh helper for local dev
- Installs mkcert, generates certs, shows device setup instructions
To trust on new devices:
1. Download: http://stegasoo.local/static/ca/rootCA.pem
2. Install as trusted CA in browser/OS

The code now explains itself like a friend teaching you crypto:
- DCT module: Why mid-frequency? What's QIM? Why is scipy being weird?
- Steganography: How LSB actually works with visual examples
- Crypto: The multi-factor security model with ASCII art diagrams
Also adds kickoff-pi-test.sh - one command to flash, wait, setup, test.
No more manual steps between flashing and seeing if it works.
Comments should teach, not just describe. If you're reading the code
trying to understand how DCT steganography works, these comments
should actually help. Novel concept, I know.
