Tree Ring Memory v0.12.0 remains protocol-preview and adds an explicit, controlled workflow-proof surface.
Highlights
- Controlled paired agent-workflow evaluation across no-memory, raw-memory, and Tree Ring retrieval arms.
- Retained per-trial workspaces, explicit model identity, and exact structured-output validation.
- Hardened proof output validation against symlink and hard-link substitution.
- Refreshed public certification evidence and release metadata.
Verification
- Tagged main CI passed.
- Tag-built Linux and macOS packages passed.
- Full local certification passed: install, CLI, performance, harness, recall-quality, and seven memory-quality scenarios.
- Package contents, checksums, and the macOS ARM64 binary version were verified after download.
Controlled workflow evidence
Codex CLI 0.144.0 with gpt-5.6-luna completed 9 retained trials:
- Tree Ring: 3/3
- Raw memory: 3/3
- No memory: 2/3
Tree Ring recorded one observed win over no memory and zero over raw memory. This is controlled fixture evidence, not a claim of universal superiority over raw context or all agent workflows.
Assets
- macOS ARM64 archive and SHA-256 checksum
- Linux x86_64 archive and SHA-256 checksum
