Transition the AX architecture from asynchronous event queues (Redis Streams
and the `ax-controller` worker pool) to direct, synchronous reconciliation in
`ax-server` guarded by fine-grained distributed locks.
Key changes:
- Implement per-resource locking (`lock:task`, `lock:workspace`, `lock:model`)
using Redis distributed locks (`SET NX PX` with token validation) and an
in-memory locker for testing.
- Move Substrate reconciliation directly into `ax-server` for Task, Workspace,
and Model lifecycle methods (`Create`, `Resume`, `Suspend`, `Delete`).
- Decommission `ax-controller`, `deploy/ax-controller.yaml`, and Redis Stream
event publishing/consuming interfaces.
- Simplify `ax delete` and `ax watch` in the CLI to eliminate two-phase
polling loops now that operations complete synchronously.
- Update `demo.sh`, build configurations (`Makefile`, `.ko.yaml`), and
documentation to reflect the single-binary control plane architecture.
* Replace UpdateTask with CreateTask and enforce immutability
Replaced UpdateTask RPC with CreateTask. Tasks are now
immutable once created; modifying an existing task returns a
FailedPrecondition error.
- Renamed UpdateTask/UpdateTaskRequest to CreateTask/CreateTaskRequest.
- Checked existence in Server.CreateTask to prevent mutation.
- Updated CLI apply logic, tests, and documentation.
* refactor: remove TaskSpec.Suspend and default new tasks to suspended state
* chore: update default snapshots bucket to snapshot-substrate-test-ax-substrate
AX is undergoing a significant redesign, moving away from a single CLI with
an embedded Python harness toward a general-purpose orchestration layer for
agentic tasks. The repository is reorganized around three binaries: ax-server
exposes a gRPC API for submitting Task manifests, ax-controller runs as a
horizontally scaled reconciler that consumes work from Redis Streams, and
ax-task-runner executes tasks inside sandboxed workers. Task state now lives
in Redis rather than Kubernetes CRDs so the system can handle millions of
short-lived tasks without straining etcd. The legacy Python harness, ATE
client, SQL event log, and skill examples are removed, and new design,
concepts, manifest, networking, runner, and sandbox docs plus Kubernetes
deploy manifests describe the new architecture.
