#!/usr/bin/env bash
# scripts/run-verify-parallel.sh — parallel verify dispatcher.
#
# Runs the 19+ verify checks (privacy, jsonb, source-id, … + typecheck +
# admin-build) as background jobs, waits for all, aggregates exit codes,
# surfaces failed-check name + tail of its log to stderr.
#
# Replaces the sequential `&&`-chain in package.json's `verify` script.
# Wallclock: 19 sequential checks (~15-25s on CI) → parallel (~3-5s).
#
# Usage:
#   bash scripts/run-verify-parallel.sh              # run every CHECK below
#   bash scripts/run-verify-parallel.sh --dry-list   # print check list, exit
#
# Env overrides:
#   GBRAIN_VERIFY_TIMEOUT       per-check wallclock cap, seconds (default 120)
#   GBRAIN_VERIFY_LOG_DIR       where to write per-check logs (default tempdir)
#
# Exit codes:
#   0   all checks passed
#   1   one or more checks failed (full details in stderr)
#   2   usage error / no checks defined
