Summary
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). Its Assistant and Turn Tail definitions fold packed historical Assistant runs without expanding their members.
Table of Contents
System prompt row
Chat shows a collapsed System prompt row for each non-empty initial or resumed request, explicit message-series start, or real system-field change. It does not repeat the row for same-series config-only or tool-only changes, tool steps, or retries. The row appears before that request's user messages, matching the provider envelope, and expands to the exact model-visible text with its original line breaks. A partial history window renders a non-initial header conservatively until the preceding page arrives; a header without a system prompt creates no row.
Turn token usage
A completed Turn shows an expandable usage row only when the loaded window includes turn/start and every started model attempt reports safe, exact usage. The row omits unavailable optional buckets. Incomplete or contradictory accounting hides the complete disclosure instead of presenting a partial total.
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. Turn navigation likewise represents only loaded Turns; loading an earlier page preserves existing Turn marks and redistributes the complete loaded set in a compact rail without an unloaded-history placeholder. Marks stay 10px apart until the loaded set exceeds the available height, then compress to fit.
