Your agent should know what is true, what changed, and what to ignore.
Your coding assistant forgets everything between sessions.
Most memory tools solve storage. None of them solve trust.
Fixed a bug last week? Your agent doesn't remember. Same error, same fix, every session.
Old rule says "always do X." New rule says "never do X." The agent sees both and picks randomly.
Long conversation compresses. Your agent loses the project map, the decisions, the preferences.
Is that memory from yesterday or last month? Is it still valid? Nobody knows. Not even the agent.
Every memory has a status. Your agent knows what to trust.
Validated memories rank above hypotheses. Deprecated ones are excluded entirely.
Finds contradictions between active memories. Separates real conflicts from duplicates.
Flags memories when source files change, go missing, or haven't been updated.
Every memory knows where it came from: source file, section, content hash.
Scores your memory system 0-100. Know exactly how trustworthy your agent's knowledge is.
No cloud, no API keys, no vector DB. Just SQLite. Your data stays on your machine.

We're building a dashboard for conflicts, stale memory, health history, and team memory.
