The default spawnAgentRunner shells out to a configurable command (default 'claude --permission-mode acceptEdits -p ', overridable via HP_WORKER_AGENT_CMD) in the task worktree, captures stdout/exit code with a wall-clock timeout, and returns a structured outcome (success on exit 0, failed/timeout otherwise) so the controller can ack/nack. runTask is pure of process/exit concerns and unit-tested with a FAKE runner (success + timeout + failed paths) that never spawns claude. main() is now guarded by an entry-point check so importing the module in tests is side-effect free. Backlog (phase 7): new src/backlog/ generator that produces canonical Tasks (kinds.ts shape) and enqueues them via the existing QueueClient.enqueue route. Sources: a TODO/FIXME code scan (git grep, scanner injectable) and an explicit list/JSON input, with a failing-test source seam ready to drop in. --dry-run prints the Tasks without POSTing; a CLI entry (dist/backlog/cli.js) wires the flags. Vitest covers dry-run, task shape, dedupe, and enqueue.
