📊 DEPENDENCY HEALTH ANALYSIS

Current Status: ✅ STABLE

Positive Indicators:

Custom forks with fixes: We’re using forks with specific bug fixes
Type safety improvements: The forks address dialyzer warnings
Active development: Both jido and jido_signal are actively maintained
No breaking changes: Our implementation remains compatible

Potential Concerns:

Fork dependency: We depend on custom forks rather than main branches
Merge timeline: Waiting for PRs to be merged upstream
Version tracking: Need to track when we can switch back to main releases

Mitigation Strategies:

Regular upstream sync: Monitor main branch for PR merges
Test coverage: Comprehensive tests ensure compatibility
Version pinning: Specific commit references prevent unexpected changes

🔮 FUTURE JIDO INTEGRATION OPPORTUNITIES

Near-Term Enhancements

Enhanced Error Handling

# More sophisticated error recovery
def on_error(agent, error) do
  case error do
    {:gradient_overflow, _} -> reset_optimization_state(agent)
    {:validation_error, _} -> revert_to_safe_state(agent)
    _ -> delegate_to_supervisor(agent, error)
  end
end

Persistence Integration

# State persistence for cognitive variables
use Jido.Agent,
  persistence: [
    adapter: :ets,  # or :mnesia, :postgres, etc.
    state_key: :cognitive_variable_state
  ]

Advanced Signal Routing

# Conditional routing based on agent state
routes = [
  {"gradient_feedback", 
   Jido.Instruction.conditional(
     condition: &gradient_overflow_check/1,

     fallback: GradientFeedbackAction
   )}
