no accepted field is silently ignored; an error never emits normal finish plus `[DONE]`. | | 13 | P1 | **Native Anthropic Messages facade and replay.** Complete the second major SDK contract. | Anthropic adapter/core stream, isolated wire translator, conversation accumulator | 2, 10, 12 | Official Anthropic SDK blocking/streaming fixtures pass; signed/redacted thinking, tool lifecycle, usage split/timing, stop reasons, and errors round-trip; history is not flattened to transcript text. | | 14 | P1 | **Operation × profile × model capability evidence.** Replace coarse provider booleans. | `catalog/live/*`, `catalog/v1.go`, `provider/adapters/provider_registry.go`, new profile schema | 5 | Every built-in deployment has explicit `supported/unsupported/unknown` rows for chat, stream, tools, schema, reasoning, image/audio input, output media, embeddings, rerank, batch, and passthrough, qualified by model/profile/runtime version/evidence/freshness. | | 15 | P1 | **Endpoint profiles and bounded native metadata.** Distinguish generic OpenAI, Ollama, llama.cpp, vLLM, SGLang, and LocalAI. | new read-only profile package; Ollama/llama.cpp/LocalAI adapters; catalog live importer | 10, 14 | Ollama native `/api/tags` and `/api/show` are read without weight lifecycle; llama.cpp `/props` and model/slot metadata are bounded and namespaced;

middleware order is deterministic; `wrapGenerate` and `wrapStream` preserve terminal/cancel/usage/route state; middleware cannot launch processes, mutate management state, or receive raw ambient credentials. | | 19 | P1 | **Sticky affinity and P2C/PeakEWMA.** Improve local/fleet routing without shared infrastructure. | `router/strategy.go`, `router/router.go`, runtime snapshot state | 3, 9, 17 | Host supplies bounded scope/key; opt-out works; P2C selection is deterministic under seeded fixtures and avoids fastest-instance herding; state persists across engine calls and never crosses tenant scope. | | 20 | P1 | **Prove signed manifest operation or keep experimental.** Add TLS/process/restart/partition evidence, not new control-plane features. | `router/controlplane/*`, persisted last-good state, process/TLS test harness | 3, 11 | A second process fetches a signed manifest over TLS, survives peer outage, rejects stale/conflicting revision, restarts from persisted last-good state, and is drained on shutdown; no consensus/autoscaling/UI scope is added. | | 21 | P2 | **Optional operation ports.** Formalize embeddings, batch, rerank, media, and moderation only as separate capabilities. | `provider/core/embedding.go`, `provider/batch/*`, `provider/media/*`, rerank/moderation, capability registry | 10, 14 | Each operation has an independent interface and conformance suite; unsupported state is explicit; `core.Provider` remains four methods; asynchronous polling remains host-driven and bounded. | -| 22 | P2 | **Migration and compatibility diagnostics.** Provide a library/CLI report, not a migration control plane. | preflight/capability APIs, catalog/registry, optional CLI outside core | 11, 14, 15 | Given a target gateway/request, Flux reports effective provider/model/deployment, supported/transformed/dropped fields, loss warnings, and required host action;

raw mode is explicit, versioned, redacted, size-bounded, and never leaks untyped SDK objects into stable DTOs; canonical mode warns on every lossy conversion. | | 24 | P2 | **Extract genuinely adoptable delivery modules.** Make optional surfaces public or remove them from the promise. | `internal/api`, `internal/grpc`, `internal/sdk/*`, new separate modules/workflows | 11, 12, 13 | Any retained HTTP/gRPC/SDK is independently versioned, externally importable, route/schema tested, and covered by root/consumer CI; unsupported stubs are removed or clearly experimental. | -| 25 | P3 | **Evaluation and external semantic-guardrail ports.** Export stable evidence without shipping products. | telemetry/event export, deterministic guardrail wrapper, optional host callback | 1, 2, 16 | A host can replay a privacy-safe completed fixture and receive a typed score/callback result;

optional Ollama/llama.cpp/Triton/Xinference clients | 11, 14, 15 | Generation never implicitly downloads/loads/deletes; admin calls require separate credentials, explicit operation, idempotency key, timeout, audit event, and safe status;

This is a notably concrete migration pattern. [CLI launch announcement](https://llmgateway.io/changelog/cli-launch-coding-agents) - **Runtime:** The unified self-hosted image combines Hono/Next services, PostgreSQL, Redis, UI, playground, and gateway.

Tools, structured output, embeddings, and batches are not documented. [Repository](https://github.com/openziti/llm-gateway) - **Routing:** Weighted round robin, active health checks, passive failover, and VM sleep detection are aimed at real inference-server pools. Its optional semantic router cascades keyword heuristics, embedding similarity, and an LLM classifier when no model is supplied. [Repository](https://github.com/openziti/llm-gateway) - **Runtime:** One Go binary, YAML, Prometheus metrics, and no database/message queue/sidecar. OpenZiti/zrok is optional and provides identity-based, encrypted ingress/egress through overlay networks.

Copy only the explicit semantic-routing cascade as an opt-in strategy after measuring its latency/cost; do not make an extra LLM call or overlay network a default dependency. +- **Mux implication:** Its single-binary scope is highly aligned, but the project is much smaller.

This prevents an OpenAI-compatible endpoint from being treated as full parity merely because it accepts a text request ([catalog/live/types.go:26-43](https://github.com/GrayCodeAI/mux/blob/main/catalog/live/types.go#L26-L43); [catalog/discover/merge.go:156-202](https://github.com/GrayCodeAI/mux/blob/main/catalog/discover/merge.go#L156-L202); [provider/adapters/provider_registry.go:62-70](https://github.com/GrayCodeAI/mux/blob/main/provider/adapters/provider_registry.go#L62-L70)). +- **P1 — turn thin wrapper tests into shared conformance profiles.** A reusable provider profile should assert auth headers, base URL/path, request-size policy, non-streaming shape, SSE framing/terminal event, usage, structured errors, retry status, cancellation, and Ping behavior. This scales better than duplicating three-test smoke suites for every gateway ([provider/adapters/opengateway_test.go:16-65](https://github.com/GrayCodeAI/mux/blob/main/provider/adapters/opengateway_test.go#L16-L65); [provider/core/stream.go:31-89](https://github.com/GrayCodeAI/mux/blob/main/provider/core/stream.go#L31-L89)). +- **P1 — define stream deadlines and terminal invariants.** Add separate initial-response, first-token, inter-chunk idle, and total-deadline policies; require every stream path to close its body, honor context cancellation, and emit exactly one terminal state.

These are concrete reasons to add conformance tests before adding new framework-like features. **Recommended contract additions (additive where possible):** 1. Add a stream event envelope with `Sequence`, `CallID`, `TurnID`/`SegmentID`, `Phase` (`start`, `delta`, `complete`, `error`, `cancelled`), `Index` for parallel/tool blocks, and an optional `ProviderBlock`/provider metadata field. Preserve `ToolCall.RawArguments` and `ProviderMetadata` through `engine.normalizeEvent`. 2. Define a terminal invariant: exactly one terminal outcome per call/continuation segment (`done`, `error`, or `cancelled`), with usage and route attached consistently. A stream must not appear complete merely because the provider stopped sending text; this follows the OpenAI completion lesson and is more robust than current implicit channel closure.
