- StepRecord adds edgePrompt field (backward compat: defaults to "")
- StepNode CAS schema includes edgePrompt
- writeStepNode persists ctx.edgePrompt
- buildHistory exposes edgePrompt in StepContext
- buildBuiltinMessages reconstructs multi-turn moderator↔agent conversation:
system = role prompt + output format (stable prefix)
per prior visit: user (edgePrompt + inter-step summary) + assistant (output)
current: user (edgePrompt + recent summary)
- Zero extra persistence — pure function of CAS chain
- Stable prefix for LLM prompt cache hits
- 10 builtin tests pass, all other package tests pass
- Add isFirstVisit: boolean to AgentContext
- Compute from steps history: !steps.some(s => s.role === role)
- hermes.ts: use isFirstVisit for first-entry vs re-entry logic
- buildInitialPrompt: always append edgePrompt as Moderator Instruction
- edgePrompt is never blanked — always the real moderator instruction
- New tests for first-visit, re-entry, and fallback scenarios
