omnigraph-server boots only from --cluster; all HTTP is /graphs/<id>/…; flat single-graph routes and the omnigraph.yaml server boot are removed. GraphRouting/ServerConfigMode collapse to multi-only; openapi.json regenerated to the nested shape; ~100 server route tests migrated; parity/system_local boot from a converged cluster. Gate green (1410 tests).
tests/server.rs (6,517 lines, 110 tests) becomes seven area files —
auth_policy, data_routes, schema_routes, stored_queries, multi_graph,
boot_settings, s3 — with shared helpers in tests/support/mod.rs. Verbatim
moves + visibility bumps (pub on helpers, pub(super)->pub inside the
matrix harness); cargo fix stripped the per-file unused imports. All 110
tests pass in their new homes (289 across the crate including lib and
openapi).
