Query the repository's own graph before grepping: which modules, files and documents a symbol, an import or a Governs edge touches, and what a change would reach. Use when a question spans directories, when asked what depends on something, when grep returns hundreds of hits or none, or when someone asks for RAG, semantic search or a code index for their codebase.

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

# One graph, two tiers

Governs: shared/scripts/index/

Retrieval fails in repositories for a specific reason: the useful unit is not a
paragraph, it is a symbol and its neighbourhood. A chunk-and-embed pipeline
returns files that talk *about* authentication; what the task needs is the four
functions that would break.

So: **one graph, built from source, queried two ways.** Not a stack of
retrievers — an extra retriever whose results have to be merged is a second
ranking problem on top of the one you had.

## The graph

Nodes are `file:<path>`, `sym:<path>:<name>`, and `doc:<path>`. Edges:

| Edge | From | Weight |
|---|---|---|
| defines | file → symbol | tree-sitter tags |
| references | file → symbol | tree-sitter tags, split across definers |
| imports | file → file | resolved import statements |
| calls | symbol → symbol | call sites inside a definition's span |
| governs | doc → path | a `Governs: src/billing/` line in the doc's head |
| supersedes | doc → doc | `Supersedes: 0004` |

**A symbol node is keyed by the file that defines it.** Keying by bare name
merges every definition sharing it, and the merged node then dominates the
…

How to install

The exact contents, by fingerprint
mdr add wangchangxin0809/cc-repo-harness/repo-index@sha256:4534fd72dca6c166

The line at the top of this page pins the label git:20260903.c1a383c, 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.
