Phase 2.3a Error Analysis and Fixes

Summary

After Phase 2.3a implementation, we have 29 test failures that need systematic fixing.

Error Categories

1. High Priority - Critical Function Errors

A. FunctionClauseError in Bridge.emit_signal/2

Pattern: FunctionClauseError in Keyword.get/3 Root Cause: Bridge.emit_signal/2 expects signal parameter to be a keyword list but receives a map/struct Files Affected:

• lib/jido_foundation/bridge.ex:550
• Multiple test files using emit_signal

Error Example:

** (FunctionClauseError) no function clause matching in Keyword.get/3
The following arguments were given to Keyword.get/3:
  # 1: %{data: %{result: "success", task_id: "task_1"}, id: -576460752303423100, type: "task.completed", time: ~U[2025-06-29 14:42:44.841693Z], source: "agent://#PID<0.1172.0>"}
  # 2: :bus
  # 3: :foundation_signal_bus

B. CaseClauseError in MABEAM.Coordination functions

Pattern: CaseClauseError: no case clause matching Root Cause: Coordination functions receive agent registry data but missing case clauses for different data structures Files Affected:

• lib/mabeam/coordination.ex (multiple functions)
• Test file: test/mabeam/coordination_test.exs

Error Example:

** (CaseClauseError) no case clause matching: [{"inf_agent_1", :pid1, %{node: :node1, resources: %{...}, capability: :inference, health_status: :healthy}}]

2. Medium Priority - Code Quality Issues

C. Unused Variable Warnings in TaskAgent

Files: lib/jido_system/agents/task_agent.ex:264,255 Variables: process_instruction, validate_instruction

3. Low Priority - Test Code Warnings

Pattern: Unused variables in test setup/helper functions Files: Multiple test files with unused registry, agent, measurements variables

Fix Plan

1. Fix Bridge.emit_signal parameter handling - Convert signal to proper format
2. Add missing case clauses in MABEAM.Coordination - Handle different agent registry structures
3. Fix unused variables in TaskAgent - Use variables or prefix with underscore
4. Clean up test warnings - Prefix unused variables with underscore

Expected Outcome

All 330 tests passing with 0 failures, 0 warnings.
