phase-memory

phase-memory is the profile-driven memory operating layer for agentic systems. It interprets Markitect memory profiles as runtime plans, models memory phases, and produces deterministic dry-run actions for retention, refresh, compaction, stabilization, and activation.

The first implementation slice is local-first and dependency-light. It does not launch a service or mutate durable memory stores by default.

Repository Role

Adjacent repositories own nearby but separate concerns:

• markitect-tool: memory profile, graph, event, and selection contracts plus context-package compilation.
• kontextual-engine: durable knowledge/runtime records, permission-aware retrieval, audit records, and long-lived storage.
• infospace-bench: concrete pilots, restart-package evaluation, metrics, and fixture feedback.

phase-memory owns the orchestration layer between them:

• phase semantics: ephemeral, fluid, stabilized, rigid
• profile execution planning
• retention, deletion, refresh, compaction, and stabilization decisions
• activation planning under token and item budgets
• adapter, policy, audit, and observability boundaries

Quick Start

python3 -m pytest

The default test suite uses only deterministic local fixtures.

Package Map

• phase_memory.models: domain records, phases, lifecycle states, diagnostics, and plan envelopes.
• phase_memory.contracts: Markitect-compatible profile/graph ingress.
• phase_memory.planner: profile execution planning.
• phase_memory.lifecycle: dry-run lifecycle planning.
• phase_memory.activation: Markitect-compatible activation selection planning.
• phase_memory.ports: runtime port protocols.
• phase_memory.adapters: deterministic in-memory test adapters.
