Use when you need to understand the RARA codebase structure — what each file does, where subsystems live, and how they connect. The index maps every source file to its role.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# RARA Codebase Map

One-line index of every source file, grouped by subsystem.

## Memory Subsystem

| File | Lines | Role |
|---|---|---|
| `memory_store.rs` | 15 (facade) | Facade including `memory_types`, `memory_store_impl`, `memory_records`, `memory_store_helpers` |
| `memory_types.rs` | 211 | Enums + structs: `MemoryLabel`, `MemorySource`, `MemoryRecord`, `NewMemoryRecord`, `MemoryRecordPatch`, `MemoryRecordSearchHit` |
| `memory_store_impl.rs` | 268 | `MemoryStore` struct + CRUD: `insert`, `search`, `get`, `update`, `delete`, `set_pinned`, `list_recent` |
| `memory_records.rs` | 185 | `PersistedMemoryRecordFile` + `MemoryRecordFileStore`: file-based persistence with atomic writes |
| `memory_store_helpers.rs` | 372 | Utilities: `clamp`, `truncate_string`, `sort_memory_records`, `default_record_path_for_vdb_uri`, `MemoryMetadata` |
| `memory_store_tests.rs` | 587 | 17 integration tests for insert/read/update/delete/search cycles |
| `memory_distiller.rs` | 315 | LLM-powered memory distillation: `distill_thread_markdown()`, `dedupe_memory_drafts()`, `new_memory_record_from_draft()` |

How to install

The exact contents, by fingerprint

mdr add linkerdog/rara/rara-codebase@sha256:d47707a0004256df

The line at the top of this page pins the label git:20260727.f48e907, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
