AGENTS.md now holds only design principles and repository metadata:

• Removes the "Known gaps" section and the sentences that pointed to it.
• The boundary table says each row names the protocol's code entry point and its document.
• The adapter bullet points to the Sandbox Provider guide and Harness onboarding for how to add an adapter.

The gap list goes to the owner as code follow-ups instead.

Checks: scripts/check-names.py; scripts/core-distribution-manifest.test.py (19 tests, including the repository-wide Markdown link test).
