Adds `ts-sdk/` — a TypeScript SDK for authoring and running Airflow tasks in Node.js. Supports two execution modes: - **Coordinator mode** (AIP-108): spawned as a subprocess by `TypescriptCoordinator`; communicates over TCP with the Airflow supervisor using the same 4-byte length-prefixed msgpack protocol as the Python and Java SDKs. Supports all 13 `TaskClient` APIs (Variables, XCom, Connections, Dag operations, secret masking) and DAG serialization. - **Edge Worker mode** (AIP-69/72): long-lived HTTPS worker using JWT authentication; picks up tasks from the edge executor queue. Wire types are generated from the supervisor schema (introduced in PR apache#67235) at `ts-sdk/schema/supervisor-schema.json`, pinned to `SUPERVISOR_API_VERSION = "2026-06-16"`. Includes unit tests (180 tests) and integration test workers.
- Remove references to internal dev notes (COORDINATOR.md, TESTING.md, SDK_COMPARISON.md, REVIEW_OBSERVATIONS.md, REFACTOR_NOTES.md) that are not part of this PR - Add esbuild bundling command and coordinator config example - Add mode-limitation table documenting which TaskClient methods are edge-only vs coordinator-only - Add logging section explaining coordinator structured logs vs edge stdout - Add @throws JSDoc to 5 coordinator-only TaskClient methods so IDEs surface the limitation on hover
…ing docs Update the default provider version fallback from 3.5.0 to 3.7.0 to match current breeze/Airflow releases; set via AIRFLOW__EDGE__PROVIDER_VERSION if your deployment uses a different version. Expand edge-mode E2E testing docs with required env vars, per-scenario worker commands, and a breeze-specific note about the is_stale scheduler gate that can strand queued runs when DAG files are freshly copied.

Add `ts-sdk/` — a TypeScript SDK for authoring and running Airflow tasks in Node.js. Supports two execution modes:
Coordinator mode (AIP-108): spawned as a one-shot subprocess per task by `TypescriptCoordinator` (companion PR); communicates over TCP with the Airflow supervisor using the same 4-byte length-prefixed msgpack protocol as the Python and Java SDKs. Supports all 13 `TaskClient` APIs (Variables, XCom, Connections, Dag operations, secret masking) and DAG serialization.
Edge Worker mode (AIP-69/72): long-lived HTTPS worker using JWT authentication; picks up tasks from the edge executor queue.
Both modes share `registerTask()` and the same `TaskClient` interface — handlers are mode-agnostic.
