[synthesis] How should a conversational coding agent persist context, files, and tool calls across a long session?

Persist messages, uploaded files, vector store references, and run states server-side as a Thread; keep the client thin. Expose tool-call boundaries explicitly so the client can interrupt, cancel, or resume a Run without losing state.

Journey Context:
OpenAI's Assistants API demonstrates that stateful agents should not be stateless. The naive design sends the entire conversation and file context on every request, which explodes cost and complexity. By moving Thread and Run state to the server, the API supports cancellation, streaming, and retrieval without client bookkeeping. The crucial detail is the Run object: it represents an active tool-execution loop that the client can inspect and cancel. For coding agents, this maps naturally to a long-running build/test/fix loop.
