0.1.0 - 2026-08-14

Added

Initial SDK release with simulator transport, all public modules
Public packages: org.ortho32, device, fabric, compute, tensor, trace, verify, security, agent, system, transport, exceptions
Core types: OrthoRuntime, OrthoSession (AutoCloseable), OrthoContext, OrthoVersion, OrthoResult, OrthoDevice family
Fabric types: FabricCommand, FabricCompletion, FabricAddress/Opcode/Epoch/Slot — logical API, no BAR access
Tensor types: Tensor, TensorShape/Buffer/Job/Operation/Result, TensorLatency (TMUL=4, TLOAD=5, TSTORE=5, Scratchpad=2) — cycles are architectural integers
Trace types: ExecutionTrace, CycleRecord, TraceHash (SHA-256 canonical), TraceComparator — H=0 determinism
Verification types: 12 theorems, TheoremId/Result, VerificationStatus (VERIFIED != TESTED != ASSUMED), CrossVerificationResult with MISMATCH blocking
Security types: Capability, Permission, SecurityContext, Attestation
Agent types: AgentIntent, AgentTask, AgentResult via typed intents
Transport: OrthoTransport (internal), SimulatorTransport (deterministic, no hardware), NativeHostTransport, PCIe/USB/Ethernet stubs — transport-agnostic API
Schemas: fabric-command, fabric-completion, execution-trace, theorem-result, attestation
Examples: device-list, tensor-run, trace-replay, proof-verify, agent-client
Integration tests: SimulatorTransportTest, TensorJobTest, DeterminismTest, TraceComparatorTest, VerificationStatusTest, CrossVerifyTest, SessionLifecycleTest, TransportAgnosticTest — all runnable offline
Build: Gradle Kotlin DSL, Java 21 toolchain, reproducible builds, sources & Javadoc JARs, Maven publication, dependency locking, checksums
Compatibility tuple: SDK-Version + Fabric-Protocol-Version + Device-ABI-Version
