Execution Package

An Execution Package is the durable unit of Verchestra delivery. It binds:

  • source identity and digests;
  • requirements and accepted decisions;
  • ordered, verifiable tasks;
  • policy and authority requirements;
  • expected artifacts and evidence;
  • checkpoint and recovery state;
  • independent verification and human-review gates.

The package is provider-neutral. Claude Code, Codex, and OpenCode/Qwen can interpret it through different drivers, but none may silently change its accepted requirements.

Packages are append-oriented and content-addressed. A material change produces a new identity and invalidates stale approvals.
