CONTINUUM vs projectmem
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.; projectmem: projectmem is an open-source, local-first memory and judgment layer for AI coding agents, designed to capture persistent records of project development, including issues, attempts, fixes, and decisions. It aims to make AI experienced, preventing repetition of past failures and significantly reducing token usage by providing distilled context.

Features
CONTINUUM01Semantic 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.
projectmem01Pre-Commit Warnings: Warns developers before committing if they're repeating failed approaches, modifying high-churn files, or touching unresolved issues.
02Local-First and 100% Private: All memory and data reside locally in a `.projectmem/` directory with no cloud, accounts, or telemetry.
03Global Dashboard: Provides a unified view of all `pjm init`-ed projects, showing grades, issues, savings, and a 'needs attention' list, aggregated at read-time.
04Code Structure + Judgment: Overlays failure heat from the event log directly onto the codebase's import graph, highlighting files with repeated failed attempts.
05Smart Context Injection & Token Efficiency: Distills raw event logs into compact, AI-readable summaries and provides token-budgeted memory blocks, significantly reducing token cost.

Use Cases
CONTINUUM↳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.
projectmem↳Preventing AI agents from repeating past debugging attempts or failed architectural approaches.
↳Improving AI agent efficiency and reducing token costs by providing distilled, context-aware project memory instead of re-reading raw files.
↳Visualizing project development history, including issues, fixes, and decisions, to understand codebase evolution and identify problem areas.
↳Onboarding new developers or bringing AI agents up to speed on a project quickly by injecting pre-existing project knowledge and decisions.
↳Providing a persistent, auditable record of AI agent interactions and learning within a project.
