EAGLE (rtx-inference/src/eagle.rs, ~610 lines, mirrors medusa.rs
conventions): EagleDraftHead autoregressive FFN with Concat/Add/
Attention feature fusion, EagleHeads draft model with draft/
draft_steps (per-step top-k for candidate trees) and teacher-forced
training_loss; implements the speculative::EagleDraftModel trait so it
plugs into the orchestration layer. 38 unit tests.

Tokenizer (rtx-inference/src/tokenizer.rs): ServingTokenizer enum —
Vocab (HuggingFace tokenizers, loadable from tokenizer.json) or
ByteLevel fallback preserving previous behavior. rtx-serving-api's
AppState and rtx-streaming's token generator now encode/decode through
it (with_engine_and_tokenizer / set_tokenizer added; existing
signatures unchanged). Also fixes two pre-existing compile errors in
rtx-streaming (missing import, stray .await) that blocked its lib
tests entirely.

Tests: rtx-inference 328 pass, rtx-serving-api 193 pass, rtx-streaming
53 pass (2 pre-existing mock-server connection failures unrelated to
these changes).

osobhandClaude Fable 5 64ade03ab9 fix(production): wire real inference path through engine, serving, and streaming
- rtx-inference: sample_next_token now copies the actual logits from the
  forward pass (Tensor::to_vec, last-token slice) instead of sampling
  from a fabricated all-zero vector; request metrics report measured
  queue/processing times instead of hardcoded constants.
- rtx-serving-api: depends on rtx-inference; /v1/completions dispatches
  to a shared InferenceEngine (byte-level tokenization until a real
  tokenizer is threaded through) and returns 503 when no engine is
  loaded instead of mock text. ServingServer::with_engine attaches one.
- rtx-streaming: depends on rtx-inference; generate_tokens delegates to
  an attached backend engine and errors without one instead of emitting
  "token_N" placeholders; tokenization is byte-level, not position-mod.
- speculative decoding: document the orchestration (speculative/) vs
  implementation (medusa.rs/lookahead.rs) layering; CLAUDE.md no longer
  claims a standalone rtx-speculative-decoding crate.
