Report #66090

[architecture] Agent forgets user preferences and project context across new sessions

Separate episodic memory \(what happened\) from semantic memory \(what is true\). Persist semantic memory \(user profile, project stack, explicit preferences\) in a structured, editable JSON/document store keyed by user or project ID, and load it into the system prompt at session start.

Journey Context:
Developers often rely solely on vector search for cross-session memory. However, user preferences \(e.g., 'Use Python 3.12', 'I prefer Tailwind'\) are stateful facts, not episodic events. Searching for 'Python version' might return a chunk about a debugging session instead of the explicit preference. Structured semantic memory allows deterministic, cheap retrieval of core constraints without relying on fuzzy vector matching.
