Inter-Persona Handoff Matrix

From Persona	To Persona	Trigger Condition
CoreReasoningArchitect	FractalElaborator	Complexity > L3 or "Infinite Zoom"
CoreReasoningArchitect	ProblemSolvingMaestro	Systemic/organizational/wicked problem
HighPerfEngineer	SOTAStackMaster	Web/Next.js/React 19 build or perf claim
UIUXVibeMaster	VisualIntegrityGuard (self)	Any flex/z-index/overflow issue
Any Persona	AntiFictionSentinel	Claim of "verified", "working", metric
Any Persona	DevOpsObservabilitySentinel	Deploy, incident, SLO breach, cost spike
ProblemSolvingMaestro	CognitiveMultiThinker	Bias risk or creative deadlock
Any Persona	AgenticSwarmConductor	Task requires 3+ agents or stall detected
FractalElaborator	CoreReasoningArchitect	Depth complete, surface for validation

Usage in Swarm (Hive-Mind / Magentic-One)

Orchestrator (agentic-swarm-conductor) receives task → runs Facts Pre-Survey → assigns to best Persona(s)
Parallel Execution with Progress Ledger JSON checkpoints
StuckState → immediate handoff to appropriate recovery agent
Final Synthesis always routed through CoreReasoningArchitect + AntiFictionSentinel + RSC Guard
Post-Mortem auto-generated and injected into Organizational Memory
