Render reconstructable system prompts at each request-series boundary, preserve series declarations through pre-step wrappers, and keep the presentation and replay snapshots aligned across clients.

The browser Chat target for Conversation assembly. It registers Chat event definitions and snapshot construction, supplies useChat, renders transcript nodes and details, and owns Chat-specific stores, actions, localization, and scroll restoration; historical image URLs resolve through the Conversation-owned per-session cache (ctx.uiConversation.imageUrl).
System prompt row
Chat contributes a System prompt row for a non-empty initial or resumed request, an explicit series start, or an actual system-field change; same-series config-only or tool-only changes, tool steps, and retries do not duplicate it. Chat places the first header in a step at that request's message boundary — turn start for step one, step start thereafter — before the user-role messages sent with the request, matching the provider envelope's system-before-messages order; when the preceding header is outside a partial window, a non-initial header stays at its own Event and renders conservatively until prepend supplies that predecessor. The row stays collapsed by default and mounts the complete prompt in the same 141px code-block body as an opaque context injection — model-facing text with its real line breaks, not Markdown — only while expanded; it has no streaming path. Systemless headers produce no row.
Model Experience
None, as this package renders logged conversation state in the browser and registers nothing model-facing.
KV Cache effect
None; Chat presentation does not assemble or mutate provider requests.
Known Limitations and Deferred Work
- The view reflects the loaded Session window — older transcript nodes become available only after Session Controller loads the preceding event page.
