@mobrienv/autoloop-backends

Backend drivers for autoloop: the shell-command runner and the Kiro ACP bridge.

A "backend" is the thing that actually executes a loop iteration's prompt. Two flavors ship in this package:

• shell / pi / mock — one-shot execSync through runShellCommand. The prompt is either piped on stdin or appended as an argv. Exit code + stdout are mapped onto a BackendRunResult.
• kiro — a persistent ACP session held by a worker thread, driven via SharedArrayBuffer + Atomics from the sync main loop. See kiro-bridge.ts (main-thread API) and kiro-worker.ts (worker-thread loop).

The harness doesn't know about these internals — it calls:

import {
  buildBackendShellCommand,
  runBackendCommand,
  runKiroIterationSync,
  initKiroSession,
  terminateKiroSession,
} from "@mobrienv/autoloop-backends";

See packages/harness/src/parallel.ts / iteration.ts for wiring examples.
