What’s Changed
cARL v0.4.0 introduces the adapter shim architecture.
.github/copilot-instructions.md is now the shared cARL adapter loader and GitHub Copilot entrypoint. Other supported harnesses use documented entrypoint shims that point back to the shared loader:
- Claude Code: CLAUDE.md
- Codex: AGENTS.md
- Cursor: .cursor/rules/carl.mdc
- Antigravity: .agents/rules/carl.md
Harness sync now writes the shared loader plus the relevant shim, deduplicates shared writes, and detects registry conflicts. Harness status now validates all managed files for an adapter, so shim harnesses are only healthy when both the shared loader and their documented entrypoint are present and synced.
This release also updates docs, memory, tests, and embedded adapter assets for the new shim model.
