CONTINUUM vs kaeru

CONTINUUM: CONTINUUM provides verifiable semantic recovery for long-running AI agents, preventing work duplication and token waste during crashes. It achieves this through compact semantic checkpoints, independent environment revalidation, and a provenance-aware state tracking system.; kaeru: Kaeru is a local-first, cross-agent cognitive engine for LLM agents, providing a typed property graph and a recollection layer for long-term memory. It enables multi-session and multi-agent continuity, allowing agents to maintain full context, follow provenance, and build on shared knowledge over time.

Features

CONTINUUM logoCONTINUUM
01Semantic checkpoints: Compact, versioned, inspectable state, not a transcript dump.
02Idempotent action ledger: Refuses duplicate external side effects; surfaces uncertain ones for reconciliation.
03Environment revalidation: Every checkpoint component verified against the current world before resume.
04Tamper-evident log: Hash-chained event log (36 event types) with integrity verification.
05Recovery engine: Seven recovery modes with a deterministic, sealed next-action contract.
kaeru logokaeru
01Two-tier graph (operational/hippocampus and archival/cortex) for active thinking and settled knowledge.
02Bi-temporal nature with native assertion/retraction history for time-travel queries and non-destructive conflict resolution.
03Per-initiative scoping and layered re-entry to restore project context across sessions and access archival knowledge on demand.
04Optional cross-agent sharing through a cloud tier, allowing trusted teams to share settled knowledge with safety gates.
05Structural recall based on exact name lookup, typed graph traversal, and FTS fuzzy fallback, rather than primarily vector embeddings.

Use Cases

CONTINUUM logoCONTINUUM
↳Resuming long-running AI agent tasks after crashes without replaying work, saving tokens and preserving decisions.
↳Wiring a coding agent (e.g., Claude Code, Gemini CLI) to capture file writes as hash-chained evidence and refuse duplicate side effects.
↳Integrating with various LLM frameworks (LangChain, LangGraph, OpenAI Agents SDK) to add robust persistence and verifiable recovery capabilities.
↳Ensuring the integrity and provenance of agent actions and state through a tamper-evident event log.

↳An agent needs to recall its thought process and project context from a previous session.
↳A team of agents needs to share and build upon a collective, long-term knowledge base.
↳An agent wants to capture new observations or hypotheses within a specific project scope.
↳Tracing the provenance and history of a piece of knowledge or a decision made by an agent.
