Goes from 135 MB binary with 1153 files importing go.temporal.io and 224
importing google.golang.org/grpc to a 10 MB native binary with ZERO of
either.
Deleted:
- tasks/, tasktests/, service/, chasm/, client/, api/, proto/, tools/
- cmd/tools/, components/, docker/
- schema/{cassandra,elasticsearch,mysql,postgresql,sqlite}/
- 40 tainted common/ subdirs + 7 top-level common files
- tests/testutils (no longer referenced after surviving deps drop common)
New cmd/tasksd (~100 lines) boots tasks.Embed (zap.Node) + http.Server.
New pkg/tasks/embed.go registers ZAP handlers for the SDK opcode surface
(0x0060-0x00A5). Workflow handlers return a 501 "not yet implemented"
envelope; native engine lands behind this contract.
Build: go build ./cmd/tasksd → 10 MB
Vet: go vet ./... → clean
Boot: tasksd --zap-port 9999 --http :7243
Probes: /healthz, /v1/tasks/health → 200
UI: /_/tasks/, / → 200 (embedded Vite bundle)
ZAP: _tasks._tcp on :9999 (mDNS disabled; direct connect)
go.mod: tidy. No go.temporal.io. No google.golang.org/grpc.
