💡 What: Optimized
SessionHistory.addEntryToSessionto usevault.appendinstead of reading the entire file and rewriting it.🎯 Why: The previous implementation read the entire chat history file into memory and rewrote it for every new message. This is an O(N) operation that scales poorly as chat history grows.
vault.appendis O(1) (or close to it) and much more efficient for logging/history use cases.📊 Impact: Significantly reduces I/O and memory usage for long chat sessions.
🔬 Measurement: Verified with a new regression test
