-NEKTE v0.3.0 — gRPC transport, task lifecycle, advanced cache
-
-**gRPC Transport (native)**
-- Proto service definition with 8 RPCs in `core/proto/nekte.proto`
-- Server adapter: `createGrpcTransport()` with server-streaming for delegate
-- Client adapter: `createGrpcClientTransport()` with pluggable Transport port
-- Anti-corruption layer with bidirectional proto <-> domain converters
-
-**Task Lifecycle Management (A2A-inspired)**
-- State machine: pending -> accepted -> running -> completed/failed/cancelled/suspended
-- `nekte.task.cancel`: fires AbortSignal for cooperative cancellation
-- `nekte.task.resume`: resumes from checkpoint
-- `nekte.task.status`: query lifecycle state
-- TaskRegistry domain service with auto-cleanup and domain events
-
-**Advanced Cache Architecture (CPU-inspired)**
-- SIEVE eviction (NSDI 2024): scan-resistant, O(1) amortized
-- GDSF token-cost weighting: L2 schemas (120 tok) survive over L0 (8 tok)
-- Stale-while-revalidate: serve stale, refresh in background
-- Negative caching: remember "capability doesn't exist"
-- TTL jitter: prevent cache stampedes
-- Request coalescing: N concurrent refreshes -> 1 network call
-
-**Protocol Improvements**
-- `nekte.context`: full implementation with TTL enforcement and permission checks
-- `nekte.verify`: real hash verification, sampling, and source tracking
-
-**Breaking Changes**
-- `DelegateHandler` signal parameter is required (was optional)
-- `HandlerContext.signal` is required (was optional)
-- `delegateStream()` returns `DelegateStream { events, cancel(), taskId }`
-- `Transport.close()` is required (was optional)
-- `CacheStore.get()` returns `CacheGetResult` (was `CacheStoreEntry`)
-- `CacheStoreEntry` has new required fields: `accessCount`, `tokenCost`
-- Removed: `delegate()` unary, `delegateStreamWithControl()`
