openai-alias host (Cursor): OMNIGRAPH_EMBED_PROVIDER=openai now defaults its base URL to https://api.openai.com/v1 (model text-embedding-3-large), while openai-compatible/unset keep the OpenRouter gateway default. The default is derived from the alias rather than the Provider enum, so an operator's stated intent can no longer be silently routed to OpenRouter; an explicit OMNIGRAPH_EMBED_BASE_URL still wins. New test from_env_openai_alias_uses_openai_host_not_openrouter.
single model source of truth (Cursor): remove the EmbedSpec.model field. The provider config is authoritative for the model, so a spec can no longer declare a model that is silently ignored while the API uses another (the wrong-space-vectors footgun); the embed summary reports the model actually resolved. Correct by construction rather than a truthful-echo patch.
stale @embed docs (Codex): docs/user/schema/index.md and docs/dev/execution.md still claimed @embed embeds at ingest; corrected to the real contract (catalog annotation; vectors supplied or pre-filled by 'omnigraph embed'). Also documented the openai-vs-OpenRouter base default in embeddings.md.
Greptile's RFC-status note is declined: the repo lifecycle keeps an RFC Status: Proposed while its PR is open and flips to Accepted on merge.
Replace the Gemini-only EmbeddingClient with one resolved EmbeddingConfig { provider, model, base_url, api_key } behind a sealed Provider enum (OpenAiCompatible | Gemini | Mock). OpenAiCompatible (POST {base}/embeddings, bearer, {model, input, dimensions}) covers OpenRouter — the new default gateway — OpenAI direct, and self-hosted endpoints; Gemini keeps its RETRIEVAL_QUERY/RETRIEVAL_DOCUMENT task types; Mock is offline/deterministic. EmbedRole replaces the task-type string.
from_env() resolves provider via OMNIGRAPH_EMBED_PROVIDER (default openai-compatible), base/model via OMNIGRAPH_EMBED_BASE_URL/_MODEL, and the api key from OPENROUTER_API_KEY/OPENAI_API_KEY or GEMINI_API_KEY. BREAKING (pre-release, no back-compat): the default provider is now OpenRouter, OMNIGRAPH_GEMINI_BASE_URL is dropped, and Gemini-only users set OMNIGRAPH_EMBED_PROVIDER=gemini.
Folds in RFC-012 Phase 1 NFR floor: a total-operation OMNIGRAPH_EMBED_QUERY_DEADLINE_MS deadline (default 60s; 0=unbounded) bounds the ~121s worst case, and tracing spans (target omnigraph::embedding) record provider/model/dim/attempt/elapsed/outcome. The offline 'omnigraph embed' CLI follows the resolved provider (its hardcoded gemini-only bail removed). 17 engine embedding unit tests, 4 CLI embed tests, and the search integration suite (22) pass.
Cross-query client reuse and the docs refresh land in follow-up commits.
