Code Review
This pull request introduces the Conflict-Free Replicated Semantic Graph (CFRSG) architecture for the VANCE agent, adding comprehensive documentation (ADR-21, glossary updates), configuration manifests, and implementation details for CFDI cross-validation and DCCD schema guarding in vance_agent.py, along with corresponding unit tests. The review feedback highlights a critical logical bug in the symbol mismatch check where a missing found_symbol incorrectly passes validation, and suggests improvements to handle falsy but valid proposed results and to optimize redundant dictionary lookups.

The default value in context.get("found_symbol", expected_symbol) causes the inequality check to always evaluate to False when found_symbol is missing from the context. This means that if an expected_symbol is specified but no symbol is found (i.e., found_symbol is absent), the check will silently pass as valid instead of failing. Removing the default value ensures that a missing found_symbol is correctly treated as a mismatch.

Using a simple truthiness check if proposed_result: can lead to unexpected behavior if expected_result is a falsy but valid value (such as an empty dictionary {} or list []). It is safer and more robust to explicitly check if proposed_result is not None: to ensure validation is not skipped for empty structures.

The truthiness check payload.get("result") is redundant because isinstance(..., dict) already ensures the value is a dictionary (and thus not None or other non-dict types). Additionally, binding payload.get("result") to a local variable avoids multiple dictionary lookups and simplifies the code.
