Point sophia/polaris at the catalyst world-shared serving root - #210
Merged
Conversation
ALCF declined to make /eagle/projects/Rootstock world-readable. The compromise (2026-08-04): a collaborator on the catalyst project periodically rsyncs our build root into that project's world-shared area, and that copy is what users should resolve. Update the registry entries (sophia and its polaris alias share the one Eagle install), the Known Clusters table, and the permissions runbook example — same scope as #207, which pointed at the build root before this arrangement existed. The build root stays where admin sync/smoke-test jobs run; they pass explicit --root/ROOTSTOCK_ROOT. Co-authored-by: Claude Fable 5 <noreply@anthropic.com>

Summary
ALCF declined our request to make
/eagle/projects/Rootstockworld-readable. The compromise (2026-08-04): a collaborator who owns thecatalystproject periodically rsyncs our build root into/lus/eagle/projects/catalyst/world-shared/rootstock, and that world-readable serving copy is what users should resolve. This supersedes #207, which pointed the registry at the build root before this arrangement existed.CLUSTER_REGISTRY:sophiaandpolarisnow resolve/lus/eagle/projects/catalyst/world-shared/rootstock, with a comment explaining the serving-copy/build-root split.CLAUDE.md: Known Clusters table updated, plus a sentence on the two-root arrangement.scripts/runbooks/sophia-polaris-delta.md: setup example now lists both roots — the serving copy is the audit target for user-facing readability (findings there go to its owner, since we can't write to it), the build root stays for admin work.The build root
/eagle/projects/Rootstock/rootstockremains where admin sync/smoke-test jobs run; they pass explicit--root/ROOTSTOCK_ROOTand are unaffected.Test plan
