The engine took a PORT and the SDK an Options.HostPort, so neither end
could use a unix socket for traffic that never leaves the host. The
field name was not the only obstacle: luxfi/zap bound net.Listen("tcp",
":port") and reached a peer with net.DialTimeout("tcp", addr), so a path
was refused at the dialer with "missing port in address" and could not
be bound at all. That is fixed upstream (luxfi/zap Address + Network);
this pins the commit until it is tagged.
EmbedConfig.Address, Embedded.Address, ServeGated(addr) and
client.Options.Address each take ONE address, because a port is a detail
of one transport rather than a thing every listener has. A path binds or
dials a unix socket; anything else is host:port.
TestDialRequiresHostPort became TestDialRequiresAddress: Dial needs an
address, and asserts a socket path is refused for being absent rather
than for being portless. TestE2E_UnixSocket runs a real workflow over a
socket end to end, and TestE2E_UnixSocketRebind proves the socket is
unlinked on stop so a restart binds cleanly.

NewTimer used to collapse any duration to zero — production workflows
with schedule-level timers (24h dunning, weekly roll-up) fired on
the next dispatch loop tick. Selector busy-spun at 1 kHz.
Real timer.Timer behind each workflow.NewTimer; Selector.Await
blocks on fan-in over Future.readyCh channels. StubEnv becomes
test-only; the production dispatch env in pkg/sdk/worker uses the
real impl.
Closes red-review §5.2 and §5.9.
Ports the workflow-code-facing API that base/plugins/tasks and
commerce/infra rely on today, with zero go.temporal.io or grpc
imports. Wire shape mirrors Temporal exactly so call-site migration
is a pure import-path swap.
Package layout (pkg/sdk/workflow):
env.go — CoroutineEnv interface, the one seam the worker
(pkg/sdk/worker, separately) must satisfy; Info,
SelectCase, CancelFunc. NewContextFromEnv is the
single entry point user ctx flows through.
context.go — Context interface (Deadline/Done/Err/Value), ctx
chain with WithCancel / WithValue / WithActivityOptions;
GetLogger, Now, Sleep, GetInfo.
future.go — Future + settleable impl. NewFuture / Settle split
so both the worker and the in-memory stub drive
completion through the same concrete. EncodePayload
is the Phase-1 JSON codec; Phase 2 swaps for ZAP.
channel.go — ReceiveChannel / Channel; unbuffered + buffered
chanImpl backing both user channels and signal
queues. Send/Receive/ReceiveAsync/Close.
selector.go — Selector with AddFuture / AddReceive / AddDefault;
Select delegates to env.Select and dispatches to
the matched callback.
timer.go — NewTimer schedules a durable timer Future.
signal.go — GetSignalChannel returns shared-by-name signal queues.
activity.go — ActivityOptions mirror of Temporal shape;
WithActivityOptions attaches per-call opts;
ExecuteActivity reads opts from ctx and dispatches.
reflect.go — Sole reflect use site (activity name resolution).
stub.go — StubEnv: synchronous, in-memory CoroutineEnv for
unit-testing workflow code without a worker.
OnActivity(...).Return(...), SignalAsync, AdvanceClock,
Cancel. Used throughout workflow_test.go.
workflow_test.go — 27 tests exercising Context, cancel scopes,
Now/Sleep, timers, activities (success/error/nil),
signal channels, user channels, Selector (future/
receive/default), and an end-to-end AgentTaskWorkflow-
shaped test that mirrors base/plugins/tasks.
Phase 1 determinism caveats (documented in env.go):
* No event-sourced replay yet — crashes restart from the top with
the original input. Same idempotency contract as Temporal.
* Payloads encoded as JSON, not the canonical ZAP codec.
* time.Now / rand / goroutines inside workflow code remain banned;
CI linter comes in a follow-up.
go vet clean. 27 tests pass including -race.
go list -deps reports zero go.temporal.io or google.golang.org/grpc.
