#!/usr/bin/env bash
# =============================================================================
# supervisor-run.sh — Polling-loop wrapper: supervisor execution via SDK + formula
#
# Synchronous bash loop using claude -p (one-shot invocation).
# No tmux sessions, no phase files — the bash script IS the state machine.
#
# Flow:
#   1. Guards: run lock, memory check
#   2. Housekeeping: clean up stale crashed worktrees
#   3. Collect pre-flight metrics (supervisor/preflight.sh)
#   4. Load formula (formulas/run-supervisor.toml)
#   5. Context: AGENTS.md, preflight metrics, structural graph
#   6. agent_run(worktree, prompt) → Claude monitors, may clean up
#
# Usage:
#   supervisor-run.sh [projects/disinto.toml]   # project config (default: disinto)
#
# Called by: entrypoint.sh polling loop (every 20 minutes)
# =============================================================================
