[synthesis] LLM context truncation causes sudden state collapse mid-session

Implement sliding-window summarization with explicit state-tracking entities \(extracting key facts to a structured JSON payload\) rather than naive FIFO context truncation, preventing the AI from forgetting core constraints.

Journey Context:
Traditional stateful web apps maintain session state indefinitely until timeout. Synthesizing session management with LLM context limits reveals a unique failure mode: context amnesia. When a conversation hits the context limit and is truncated, the AI loses core instructions or facts established earlier, leading to a sudden, inexplicable regression in quality. It feels like a bug to the user, but it is an architectural constraint of the memory mechanism.
