## Summary

Tree Ring Memory helps AI agents remember useful decisions, warnings,
preferences, and evidence without turning memory into raw transcript storage.
Fresh memory stays detailed, older learning compresses into rings, important
failures remain visible as scars, durable truths become heartwood, and future
ideas stay as seeds.

## What Ships Now

- Rust-native CLI and crates.
- Local SQLite/FTS storage.
- Explainable recall with ring, scope, confidence, and ranking signals.
- Explicit forgetting, redaction, supersession, audit, and maintenance.
- Deterministic consolidation without requiring an LLM.
- Source-linked evaluated outcomes through `tree-ring evidence`.
- Controlled workflow-proof artifacts with explicit model identity and exact structured-output checks.
- Same-host multi-agent identity, scoped recall, and exact-retry idempotency.
- Optional coordinator authorization for shared writes and lifecycle mutations.
- Project-local harness activation with receipt-backed readiness.
- DOX and Revolve sync adapters.
- Read-only agent-framework discovery.
- Terminal onboarding and a Ratatui operator console.
- Verified prebuilt bootstrap and scope-preserving CLI updates.

## Verified Prebuilt Install

```bash
curl -fsSL https://raw.githubusercontent.com/TerminallyLazy/Tree-Ring-Memory/main/install.sh | sh -s -- --release latest
```

Recommended project-local setup from the project root:

```bash
curl -fsSL https://raw.githubusercontent.com/TerminallyLazy/Tree-Ring-Memory/main/install.sh | sh -s -- --project --init --release latest --no-animation
```

macOS ARM64 Homebrew install:

```bash
brew tap TerminallyLazy/tree-ring
brew install tree-ring
```

Source install requires Rust and Cargo and omits `--release latest`.

## Update

```bash
tree-ring update --check
tree-ring update
tree-ring --root .tree-ring init
```

The updater verifies official assets and preserves the active install scope.
Pre-0.15 CLIs must first be upgraded with their existing manager or prefix.

## First Commands

```bash
tree-ring init
tree-ring remember "Use project-scoped recall before risky release changes." --event-type lesson --scope project
tree-ring recall "release changes"
tree-ring evidence "The eval passed after the fix." --outcome promoted --evidence-ref evals/run-042
tree-ring tui
```

## Ring Model

- `cambium`: fresh active context.
- `outer`: recent summarized learning.
- `inner`: older compressed learning.
- `heartwood`: durable high-confidence truths.
- `scar`: important failures, regressions, and warnings.
- `seed`: unresolved ideas and hypotheses.

## Privacy Boundary

Tree Ring Memory is local-first by default. It does not scrape transcripts, run
a hidden recorder, or turn terminal event pulses into durable memory. Durable
writes are explicit.
