ADLC5 5.1.0 public-preview candidate

ADLC5 5.1.0 public-preview candidate packages for Codex, Claude Code, Cursor and Hermes Agent.

Choose the archive for your agent. ZIP and tar.gz contain portable source, not a bundled interpreter or agent. Install Python 3.10+, Git, Bash 3.2+ and jq. Extract to an empty folder, inspect INSTALL.json for provenance, then run python3 install.py --dry-run and python3 install.py (Windows PowerShell: py -3 install.py). Complete the host-specific steps printed by the installer.

Installation and host behavior · OS prerequisites

Validation run: all seven archive/installer tests passed on ubuntu-latest, macos-latest and windows-latest. Tests cover all four archives, checksum/provenance, write-free dry runs, extracted ZIPs in paths with spaces, supported host command plans and preservation of existing destinations. Native host commands are mocked in installation contract tests; these results are not signed-in end-to-end qualification across every OS/host combination. Unix users should prefer tar.gz to preserve executable bits.

Includes requirements readiness, central Pulse and Settings, configuration layers, and self-install packages merged in PR #26. Documentation synchronization is in PR #27. Source: df1ee33. This is a prerelease, not a stable production certification. The comparative campaign remains unexecuted.
