fix: clone all oracle repos locally in MCP-unique task Dockerfiles

sjarmak · claude · sjarmak · commit e15e7bbc9f58 · 2026-02-21T01:16:39.000Z
All 12 MCP-unique tasks now clone every repo referenced in their oracle
into /workspace/, giving baseline equal local access to the codebases
that SG_full reaches via Sourcegraph MCP.

Previously, oracle repos marked access_mode="mcp_only" were only
reachable by the SG_full config, making the baseline comparison trivial
(structurally unable to find the answer). Now both configs have the same
information available — just through different retrieval mechanisms.

Repos added per fixture:
- kubernetes-ecosystem: +kubernetes/client-go, +kubernetes/api, +etcd-io/etcd
- grafana-observability: +grafana/loki
- multi-org-go: +etcd-io/etcd, +grafana/grafana
- nodejs-web-stack: +expressjs/express
- python-ml-stack: +numpy/numpy, +pandas-dev/pandas, +scipy/scipy

Updated: 12 Dockerfiles, 9 instruction.md files, 5 fixture JSONs.
