# scripts/iterate.sh
# One-command autonomous iteration loop for the Tesla Roadtrip project.
#
# Usage:
#   ./scripts/iterate.sh           # Full loop (smoke + E2E)
#   ./scripts/iterate.sh --fast    # Fast mode (smoke test only)
#
# This script:
#   1. Ensures dev servers are running (via ./scripts/dev.sh if needed)
#   2. Starts a fresh timestamped backend log file for this iteration
#   3. Runs the fast backend diagnostic test (smoke)
#   4. Runs the full E2E Playwright test (headed) unless --fast is used
#   5. Opens the Playwright HTML report
#   6. Shows the latest screenshots + video
#   7. Prints the relevant backend log lines from the test window
#
# After it finishes, review the artifacts and tell me what to fix.
# Then just run this script again.
