WalkthroughThe change adds server-group API contracts, Convex-backed v1 list and create routes, SDK methods, and an exported server-group DTO. Compose operations and CLI commands now accept server selectors, validate conflicting options, resolve servers, reuse or create immutable groups, and pin groups before execution. Proposal normalization can freeze resolvable selectors to server IDs while preserving unresolved input. The platform operations also add project-server connection cancellation. Tests cover routing, authentication, DTO mapping, conflicts, materialization, races, and selector normalization. Merge Risk: 🟡 Moderate · up to The change adds pinned server selection and related connection operations, but the current revision leaves the new cancellation operation incomplete across supported surfaces, causing coverage checks to fail; partial compose failures can also leave persistent resources behind, and paginated listings may create duplicate pinned groups. Merge should wait for the coverage failure to be fixed and for the lifecycle and reuse risks to be addressed or explicitly accepted. Thanks for using CodeRabbit!

Add null and empty selector tests.
Add cases for compose.server as null, "", and whitespace, plus empty compose.servers. Assert that normalization preserves the input and does not call listProjectServers.
As per coding guidelines, “All changes should include tests, covering happy paths, validation errors, error handling, and edge cases such as null and empty values.”

Paginate the server-group lookup before creating a snapshot.
listServerGroups returns a PlatformPage, but resolveComposeServerGroup scans only page.items once and does not follow nextCursor. When the matching group is on a later page, composition creates another group for the same server set instead of reusing it. This breaks content-based reuse and can exhaust the bounded name variants after repeated runs.
Add cursor support and make the lookup consume all pages, or enforce an explicit unpaginated API contract.

--compose-host recorded only the CLIENT. The server half was resolved at run time from that host's current list, so pointing the shared ChatGPT host at a different server silently repointed every eval composed against it: a suite written for Vercel would connect to Sentry, run its cases there, and report a real score for a server it was never meant to test. Nothing errored, because by the time the run resolved servers there was nothing left to notice. A composed run now has to pin its servers -- --compose-server / -group. The old live-follow is unchanged and still reachable as --compose-host-servers; what changes is that it is asked for rather than defaulted into. Enforced in composeRunEnvironment, the chokepoint both run ops share, and not in the schemas: the CLI calls execute() directly and never parses its input, so a refinement would not fire for the surface that hits this most. Scoped to the two eval run ops -- ensure_adhoc_environment composes environments rather than tests, and journeys and user-testing scenarios never compose at all, so their deliberate live-follow is untouched. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
`serverGroup: ""` cleared the check and then composed the very environment the check exists to refuse: the guard asked whether the field was present, while resolveComposeStack asks whether it is truthy, so a blank id counted as a pin here and was dropped on the way to the wire. It now asks the same question the wire does. `hostServers` alongside a pin was accepted and one of the two silently won. The CLI already rejected the pair; execute() is reachable without it, which is the surface that matters here. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
