#!/usr/bin/env bash
# run_flow.sh — drive the Customer 360 business flow against a deployed API.
#
# Each "iteration" plays a 20-call slice of realistic enterprise behaviour:
# KPI refresh → detail drill-downs → 360° composites → write operations
# (tags + notes) → cleanup → one negative validation test. 25 iterations
# = 500 inbound calls = roughly 1000+ outbound SAP/Postgres operations
# for Keploy to record at the wire level.
#
# Varies the customer ID across a small pool (11, 202, 203) to get
# diverse SAP responses, and generates unique tag names per call so
# writes always take the insert path (not the idempotent no-op path).
#
# Auto-detects the base URL; override with --host.
#
# Usage:
# ./run_flow.sh # default: 25 iterations → 500 calls
# ./run_flow.sh --iterations 50 # 50 iterations → 1000 calls
# ./run_flow.sh --host http://... # explicit URL
# ./run_flow.sh --trace # + tail correlated pod logs at end
# ./run_flow.sh --quiet # summary only
# ./run_flow.sh --iterations 1 --verbose # narrate every call in detail
#
# Exit code: 0 if all calls passed. Non-zero otherwise.
