Block Engine v2.2.5

Block Engine v2.2.5

This release strengthens the local-first engine and establishes the first reviewable package marketplace.

Included

• block.exe, block-lite.exe, and block-plus.exe with version 2.2.5.
• A secure Windows bootstrapper that downloads only the matching official GitHub Release asset, verifies SHA-256, rejects unsafe archive paths, and installs atomically.
• No automatic Winget, Chocolatey, PowerShell, or downloaded-script execution in the installer. Optional runtimes are detected and reported only.
• block pkg search, info, install --remote, verify, and remove for the official digest-pinned registry.
• A reproducible registry index generator with cross-platform integrity checks.
• Five starter packages: octopus, block-web, gblock-d, block-work, and drawing.
• block doctor --full with read-only script, package, website, and repository scans.
• Updated website, documentation, AI knowledge files, editor packages, release workflows, and regression coverage.

Trust and compatibility

The installer is a bootstrapper and requires this GitHub Release to be available. It fails closed when the release, selected asset, checksum, or archive layout cannot be verified.

The installer can be Authenticode-signed by a maintainer. This release does not include a signing certificate; a valid checksum does not by itself mean publisher trust.

Verification

All required GitHub Actions checks passed before merge, including engine smoke tests, CLI, package registry, path resolution, website security, health hardening, API integration, Community Lab, native language, native interpreter, and release-version checks.
