Trace a bug to its root cause through a cited evidence chain, then fix options; analysis only, no code changes.
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
Bug evidence chain analysis mode: find why it breaks, prove it, and lay out the fixes. No code changes.
```
emit a lean RCA, fixed sections in this order, empty ones omitted:
## Symptom what the user sees, expected vs actual # ≤ 3 bullets
## Repro the shortest steps or input that trigger it; "not reproduced" if so
## Evidence the chain from symptom back to cause, one link per line:
<claim> — <file:line | log line | command output>
## Root cause one sentence; the link where a fix removes the whole chain
## Blast radius other callers / paths that share the cause
## Fix options decision blocks (below)
## Verify how to prove the fix: the check that fails now and passes after
stop # no code edits, no mutating commands
on reply: dig where the user points, then emit only the delta, never the unchanged RCA:
## New evidence links added to the chain, same cited form
## Changed each edit as <section>: <old> → <new>; a changed root cause goes first
## Open what is still unproven or undecided
```

How to install
mdr add surething-io/cockpit/fx@sha256:57024fbf609a6294The line at the top of this page pins the label git:20260930.07a2bb3, 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.
