### ftl_code_expert/language.py
VERDICT: CONCERN
CORRECTNESS: VALID
SPEC_COMPLIANCE: N/A
ISSUE_COMPLIANCE: N/A
BELIEF_COMPLIANCE: N/A
TEST_COVERAGE: UNTESTED
INTEGRATION: PARTIAL
REASONING: 
- The `GO` `LanguageProfile` definition is syntactically and structurally correct. The `definition_patterns` are robust, including support for Go method receivers, generics, packages, and typical top-level declarations.
- However, integration is incomplete: `_CONFIG_TO_LANGUAGE` in `ftl_code_expert/language.py` was not updated to map `"go.mod": "go"`. As a result, automatic configuration-based language detection will fail for Go repositories.
- The changes are completely untested. There are no tests verifying the Go profile, its config file registration, or its regex-based definition pattern matching.

### SELF_REVIEW
LIMITATIONS:
- Could not execute pytest or view other source files via shell commands due to environment-level tool execution policy restrictions.
- Verified usages and test coverage relying on the provided observation results.
---

### FEATURE_REQUESTS
- Ensure full file context and test execution reports are automatically included in observations when shell execution commands are restricted by environment policies.
