## Dispatch contract (read this FIRST) This phase executes parallel groups via **`scripts/run-parallel-group.sh`** — one `claude --print` process per task, each in an isolated git worktree. Workers are FULL headless sessions (not Agent-tool subagents), so they load skills/hooks normally; persona guardrails are injected via `--append-system-prompt` and the model is pinned to `sonnet` for cost. Concurrency is guaranteed at the OS level; the script handles worktree lifecycle, result parsing, merge-back, and the per-group gate automatically. ### Parallel-group execution loop ``` PLAN = .claudehut/plans/<task-id>-plan.md TASK_ID = claudehut-state task-id GROUPS = sorted distinct "Parallel group:" values in PLAN (1, 2, 3 …) # ── Stub step (sequential, ONCE before any group) ───────────────────── # Scaffold compiling skeletons for every type/signature the plan introduces, # committed to the branch. Workers branch from this commit, so they cannot # invent divergent signatures (drift), reference a missing type (hidden dep), # or merge-then-break (semantic conflict).
