Agent memory as source code the agent reads itself.

0.9 release line with experimental Edges

Version 0.9.0 adds an opt-in memdsl.workspace.v3 first-class explicit Edge experiment. It does not rewrite the frozen 0.8 contract: legacy relations and authority remain compatible, explicit Edge proposals always require a human, and explicit supersedes is graph-only. Source remains runtime authority; review/audit is a workflow contract, not a non-bypassable grant ledger. See the Phase 6 design and risk matrix and the release-scope evidence freeze.

Stable 0.8 compatibility contract

The 0.8 contract combines the previously unpublished navigation and View work now shipped by 0.9.0; neither 0.7.0 nor 0.8.0 was released separately. Stable public contracts include the v1 compatibility/authority surfaces, Catalog v1, Trace v1, indexed query/search trace, report diagnostics, public rebuildable CompiledWorkspace / compileworkspace, memdsl.workspace.v2, exact use, the generic dialectmapping capability, ViewContext/ResolvedView, and the explicit opt-in v2 read schemas. Map v1 remains supported throughout the 0.8 line and will not be reconsidered for removal before 1.0.

The software release is 0.9.2, anchored by tag v0.9.2. It adds official MCP Registry metadata and a UV-based MCPB installer for the default-read-only memdsl-mcp server. Parser, schema, review, query, authority, and MCP tool contracts are unchanged from 0.9.1. Neither patch nor package-level release promotes the opt-in Edge surface to stable or makes automatic Edge generation authoritative.

The real-world rollout quality of quarantine/strict, dialect-candidate learning, and host-attested principal integration is still experimental and opt-in. Their safety invariants are not experimental: authorization happens before aggregation, incomplete hard-rule evaluation never becomes ALLOW, non-authoritative edges never gain authority, and repair paths remain open. CompiledWorkspace is a public rebuildable handle; its cache/index layout, compiler contract strings, and synthetic timing constants remain implementation details. Workspace-v3 first-class Edges are experimental. Automatic dialect learning, automatic Edge candidates, inferred authority, and cold-history/ incremental compilation are not shipped. Host extraction/sanitization and private schemas/policies/samples remain outside memdsl and are not release gates.

memdsl started with a retrieval failure. A memory system built on RAG failed to recall a memory it certainly had; a coding agent pointed at the same raw memory files traced it down in a few steps. Same model — the difference was the context contract. The agent knew the memory existed and could keep reading toward it; the retriever got exactly one similarity guess, and a miss looked identical to absence.

memdsl turns that difference into the product. Long-term memory lives in readable, lintable, reviewable .mem source files, and every runtime surface is built for an agent that reads memory itself:
