9.1 — Semantic Cache - New: src/lib/semanticCache.js — Two-tier cache (in-memory LRU + SQLite) - Signature = SHA-256(model + normalized messages + temperature + top_p) - Only caches non-streaming, temperature=0 requests - X-OmniRoute-No-Cache: true header bypass - Response headers: X-OmniRoute-Cache: HIT/MISS - DB table: semantic_cache with indexes on signature and model - New: src/app/api/cache/route.js — GET stats, DELETE clear 9.2 — Request Idempotency - New: src/lib/idempotencyLayer.js — In-memory 5s dedup window - Reads Idempotency-Key or X-Request-Id headers - Returns cached response with X-OmniRoute-Idempotent: true header - Ephemeral by design (no SQLite) 9.3 — Progress Tracking in Streaming - New: open-sse/utils/progressTracker.js - Emits SSE 'event: progress' with tokens_generated + elapsed_ms - Opt-in via X-OmniRoute-Progress: true header - Supports AbortSignal cancellation - Final event includes done: true Integration: - chatCore.js: idempotency check → cache check → provider call → cache store → idempotency save - Streaming path: optional progress transform chain - DB: semantic_cache table added to db/core.js schema Tests: 320 pass (+25 new) | Build: success
