MD Brain v0.2.0 — Public Prototype

MD Brain 0.2.0 — Public Prototype

MD Brain 0.2.0 is an experimental, local-first public prototype for portable and inspectable AI continuity. Markdown remains the source of truth, recall is bounded and explained, and durable memory changes require a reviewed proposal and explicit approval.

Included

• Memory Stratigraphy workbench with Recall, Consolidate, and Doctor views.
• Installable md-brain Python package and mdbrain CLI.
• Deterministic lexical recall with token budgets, scores, reasons, and provenance.
• Proposal rewrite validation, explicit approval, atomic writes, append-only audit journals, and fail-closed rollback.
• Loopback FastAPI surface and a sanitized 19-file fictional demo brain.
• Deterministic lifecycle, CLI/API, production web build, and Sites worker coverage.

Prototype boundary

This prerelease is not a hosted service or a production safety certification. It does not claim hosted or multi-tenant operation, semantic or embedding retrieval inside the trusted core, trusted LLM adapters that authorize mutation, concurrent multi-writer coordination, or PyPI publication.

See CHANGELOG.md, docs/architecture.md, and docs/safety-model.md for details.
