R3 adapter

Lazily.R3 is an optional net10.0 package. The core Lazily assembly has no R3 dependency.

Lazily to R3

Context.ToR3State is cold: each subscription owns one Effect, emits the current value, tracks dynamic dependencies, suppresses equal values, and detaches its edges when disposed. ToSharedR3State is explicit sharing: one owned effect feeds a one-value ReplaySubject.

An R3 error is recoverable (OnErrorResume) and does not tear down the effect. Disposing a shared bridge completes its current subscribers. Lazily batching may collapse intermediate state values, so this is a state projection, not a lossless event-stream adapter.

R3 to Lazily

Context.BindR3State requires same-thread ingress. ThreadSafeContext.BindR3State serializes cross-thread ingress through the context lock. Both return an equality-guarded Source<T> and an owned subscription. R3 errors update LastError and remain recoverable; R3 completion is terminal and recorded in Completion. Disposal unsubscribes but leaves the last state readable. Reentrant writes follow the underlying Context/ThreadSafeContext semantics, and Batch coalescing remains a Lazily concern.

Performance

benchmarks/Lazily.R3.Benchmarks permanently compares native Lazily, native R3, and both bridge directions under BenchmarkDotNet's memory diagnoser. Profiling before budgets were introduced observed 488 B/update. A later short run on .NET 10.0.10 observed 336 B/update for native Lazily and both bridge directions (native R3 allocated 0 B/update). These are environment-specific profiling observations, not budgets. Set budgets only after repeated runs on stable hardware and allocation source profiling.
