The \`GET /api/v4/projects/:id/(-/)search/semantic\` endpoint becomes available to all users on instances where semantic code search is configured and indexed. ### What can go wrong and how would we detect it? - Unexpected load on the semantic search infrastructure — monitor via Elasticsearch/pgvector dashboards - Rate limit too permissive — the \`semantic_search_rate_limit\` provides a safety valve - The flag can be disabled per-installation if scalability issues arise (\`Feature.disable(:semantic_code_search_rest_api)\`) ## Rollout Steps ### Rollout on non-production environments - [ ] Verify the flag is enabled by default on staging - [ ] Confirm the endpoint returns 200 for a provisioned project on staging ### Rollout on GitLab.com - [ ] The flag is \`default_enabled: true\` — no explicit enable step needed - [ ] Monitor for errors or unexpected load after the MR merges - [ ] Disable per-group if issues arise: \`Feature.disable(:semantic_code_search_rest_api, Group.find(id))\` ### Cleanup - [ ] Remove \`semantic_code_search_rest_api\` feature flag - [ ] Remove \`route_setting :lifecycle, :beta\` from the endpoint - [ ] Update API documentation to reflect GA status
