AI Airlock v0.2.1

First public release of AI Airlock — a local-first privacy pre-flight that creates a sanitized, verified working copy of your document before you use it with an external AI tool.

Install (Apple Silicon Mac, macOS 13+)

1. Download AI-Airlock-0.2.1-arm64.dmg below (~880 MB — the Gemma 3 1B model and llama.cpp runtime are bundled inside; that's what makes it fully offline).
2. Open the DMG and drag AI Airlock to Applications.
3. First launch: macOS will warn because this early build is ad-hoc signed. Go to System Settings → Privacy & Security → Open Anyway.

Verify your download: shasum -a 256 -c AI-Airlock-0.2.1-arm64.dmg.sha256

What's in 0.2.1

• Overlap handling hardened: emails and protected terms can never be absorbed into a keepable confidential passage — mandatory replacements stay mandatory
• Keeping one of two identical values (e.g. the same phone number twice) no longer blocks export
• Export screen now shows the saved filenames, the clean copy's SHA-256, and a warning when the chosen folder may sync to iCloud/Dropbox/OneDrive/Google Drive
• Protected terms are validated before the semantic scan starts
• Semantic scans are serialized so an abandoned scan can never disrupt a new one
• Renderer path resolution extracted, hardened against malformed and traversal URLs
• Test suite expanded from 10 to 25 tests

Supported inputs: pasted text, TXT, Markdown, and text-only DOCX (≤25 MB / ~300k characters). A clean copy is not company permission to use an AI tool — every receipt says so.
