#!/usr/bin/env bash
# Console v2 — local-MacBook dev startup.
#
# Spins up the read-local / write-remote pair documented in
# `morning-read/host-arch-spec.md`:
#
#   • FastAPI on localhost:8431 with RECOIL_WRITE_UPSTREAM set to Studio.
#     All GETs serve from the local Dropbox-synced tree (~1ms reads).
#     All mutations (POST/PUT/PATCH/DELETE) proxy to Studio.
#   • Vite on localhost:5173 (strictPort), proxies /api → localhost:8431.
#     Same `pnpm dev` config as Studio — vite.config.ts hasn't changed.
#   • ttyd stays on Studio. /api/config returns TTYD_HOST=Studio so the
#     chat iframe loads from `http://100.105.59.118:7681+`.
#
# Run from anywhere; the script normalizes its own cwd.
#
# Usage:
#   ./recoil/console-v2/scripts/dev-local.sh
#
# Tips:
#   - This script foregrounds Vite. ^C exits Vite; FastAPI is started in a
#     background subshell and gets killed on EXIT trap.
#   - Studio must be reachable over Tailscale (writes proxy there). If
#     Studio is unreachable, GETs still work; mutations 502.
