Mimir v0.5.0 — 23 MCP tools, decay, vault, synthesis
What's new since v0.2.0
Decay & Layer Progression — Ebbinghaus-inspired memory decay model. Entities degrade over a 7-day half-life and are boosted on recall. Three-tier layer system: buffer → working → core, based on retrieval count thresholds (≥5, ≥20). New mimir_decay tool recalculates all scores.
Vault Export/Import — File-system vault for backup, transfer, and offline storage. mimir_vault_export writes entities + journal to markdown files under ~/.mimir/vault/. mimir_vault_import reads them back with idempotent upserts.
Chain Traversal — mimir_traverse walks the entity link graph up to a configurable depth, returning linked chains for knowledge graph exploration.
Entity Scoring — mimir_score assigns a numeric score (e.g. 0.0—1.0) to entities for ranking and prioritization.
Expanded Recall Output — mimir_recall now surfaces body_json fields (content, summary) as top-level keys on returned items, so downstream consumers like Perseus can render them directly.
CI Pipeline — GitHub Actions workflow for build + test on every push and PR to main.
Site Refresh — Benchmark page and landing site updated with decay + vault demos.
