## Problem
After report synthesis, extra "JUDGING: ManagerAgent" and "PROGRESS: Step 11"
events appeared in the UI, confusing users. Root cause: we were treating
`ExecutorCompletedEvent` as a UI event when it's actually internal framework
bookkeeping (auto-emitted by MS Agent Framework for every executor).
## Solution
1. **Silence ExecutorCompletedEvent**: Remove UI event emission, keep only
internal state tracking (reporter_ran flag)
2. **Add metadata filtering**: Filter out `task_ledger` and `instruction`
messages from AgentRunUpdateEvent stream
3. **Remove dead code**: Delete unused `_handle_completion_event` and
`_get_event_type_for_agent` methods
## Changes
- src/orchestrators/advanced.py: Silence completion events, add metadata filter
- tests/unit/test_orchestrator_noise.py: New regression tests
- tests/unit/orchestrators/test_accumulator_pattern.py: Update expectations
- docs/bugs/P2_EXECUTOR_COMPLETED_EVENT_UI_NOISE.md: Full bug documentation
## Validation
- Senior …
* fix(deps): Upgrade agent-framework-core to 1.0.0b251204 (SPEC-18)
Breaking API changes in upstream require event class migration:
- MagenticAgentDeltaEvent → AgentRunUpdateEvent
- MagenticAgentMessageEvent → ExecutorCompletedEvent
- MagenticFinalResultEvent → (removed, use WorkflowOutputEvent)
Upstream fixed the repr bug we worked around in SPEC-17.
Keep Accumulator Pattern as safety net for now.
Closes P0: HuggingFace Spaces deployment blocked
* docs: Add SPEC-18 documentation and fix test docstring
- Add docs/specs/SPEC_18_AGENT_FRAMEWORK_UPGRADE.md with full migration guide
- Update test_accumulator_pattern.py docstring to reference new event classes
Part of SPEC-18: Agent Framework Core Upgrade
* refactor: Address CodeRabbit review feedback
- Use defensive getattr for event.data.text (consistency)
- Remove redundant isinstance check in _handle_final_event
- Update sync dates in requirements.txt and workflow-diagrams.md
- Add language specifier to SPEC-18 code block
Note:…
fix(P0): Implement Accumulator Pattern to resolve Repr Bug (#117)
