Is MemoryCustodian right for you?
A good fit for
Relevant to teams preferring explicit, versioned project memory over unbounded chat history or semantic retrieval.
Before you choose
Pre-1.0 protocol/schema migration uses separate confirmed stages. Deterministic checks do not prove semantic correctness or database ACID guarantees. User-confirmed/project-source evidence needed for active entries; agent observations remain candidates. Forgetting affects managed scope, not Git history, clones, backups or previously distributed copies. Local overlays cannot override shared constraints; inspect private-state permissions on each platform. Concurrent transaction recovery and cross-agent fixtures are vendor-described, not our live assistant tests. No install, repository initialization, memory mutation or deletion performed.
Workflow and handoff
Initialize a disposable sample, record source-backed decisions, inspect routed context and preview recovery/deletion boundaries before curating real project memory.
