 use their own runtime as long as they receive only the public task package and
 return the documented answer/artifact bundle.
 
+### Bohr CLI
+
+Of the 604 tasks, 53 are tagged `bohr-cli`. A complete run must provide an
+authenticated real `bohr` executable for those tasks and retain the audited
+`bohr_cli_receipts.jsonl` produced during solving. The other 551 tasks do not
+have a benchmark-wide mandatory Bohr CLI dependency, although Bohrium can be
+used as an optional remote-compute route when the task contract permits it.
+
+The published three-Agent runs used Node.js 22 and Bohr CLI 2.5.17. Reproduce
+that environment with:
+
+```bash
+npm install -g @dptech-corp/bohr-cli@2.5.17
+bohr version -o json
+```
+
+An unpinned `npm install -g @dptech-corp/bohr-cli` follows npm `latest` and must
+be reported as a different runtime if its version differs. The scoring process
+does not call Bohrium again; it consumes receipts and retained tool events from
+the solve. Installing the CLI after a run cannot reconstruct missing execution
+evidence. Keep the authentication cache and access key outside Agent outputs.
