Legacy subscribeAll delivers InstanceDisposed via GlobalBus because
the fiber starts asynchronously and may not be running when disposal
happens. This bridge can be removed once upstream PubSub.shutdown
properly wakes suspended subscribers.
Add forceInvalidate in Instances that closes the RcMap entry scope
regardless of refCount. Standard RcMap.invalidate bails when
refCount > 0 — an upstream issue (Effect-TS/effect-smol#1799).
Add PubSub shutdown finalizer to Bus layer so layer teardown
properly cleans up PubSubs.
Add Effect-native tests proving forkScoped + scope closure works
correctly: ensuring fires when the scope closes, streams receive
published events.
Remove stale GlobalBus disposal test (instance.ts responsibility).
The sync callback API can't wait for async layer acquisition, so
delivering InstanceDisposed through the PubSub stream is a race
condition. Instead, the legacy subscribeAll adapter listens on
GlobalBus for InstanceDisposed matching the current directory.
The Effect service's stream ending IS the disposal signal for
Effect consumers — this is only needed for the legacy callback API.
Also reverts forceInvalidate, fiber tracking, priority-based
disposal, and other workaround attempts. Clean simple solution.
Add Bus.Service as a ServiceMap.Service backed by Effect PubSub:
- publish() pushes to per-type + wildcard PubSubs and GlobalBus
- subscribe() returns a typed Stream via Stream.fromPubSub
- subscribeAll() returns a wildcard Stream
Legacy adapters wrap the Effect service:
- publish → runPromiseInstance
- subscribe/subscribeAll → runCallbackInstance with Stream.runForEach
Other changes:
- Register Bus.Service in Instances LayerMap
- Add runCallbackInstance helper to effect/runtime
- Remove unused Bus.once (zero callers)
- Skip PubSub creation on publish when no subscribers exist
- Move subscribe/unsubscribe logging into the Effect service layer
