#!/usr/bin/env python3 """ The phone's photo backup section (photo-sync-settings.js), rendered in Chrome on its page (android-sync-page.js) at phone widths with names nobody would choose for a fixture. Only the Android application has this section, and its engine is Chromium, so one engine is the whole of it. The bridge is a stand-in that answers the way the phone does; the group connection (`connection-pool.js`) is replaced in the copy by one that hands out a node with long, space-free folder names, because those are what widen a page (CLAUDE.md). Four states: choosing where backups go, setting up photos, set up with a refusal showing, and setting up with only selected photos allowed. photo_sync_probe.py prints one JSON object, keyed """ import functools import http.server import json import shutil import socketserver import subprocess import sys import tempfile import threading from pathlib import Path STATIC = Path(__file__).resolve().parents[2] / "src" / "meshbay_hub" / "static" LONG_FOLDER = "Media/Photos/Family_holidays_summer_2026_at_the_seaside_with_everyone_and_the_dog" LONG_GROUP = "A_group_name_with_no_spaces_at_all_whatsoever_long" LONG_OWNER = "someone_with_a_long_handle" FAKE_POOL = """ export class ConnectionPool { async connect() { return { transport: { fetchIndex: async () => ({ roots: [{ name: 'Media', writable: true, available: true }], dirs: ['Media/Photos', 'Media/Photos/Some_Band_Complete_Discography_1992-2000_FLAC_and_more_pictures', '__FOLDER__'], }), }, ack: { photo_directories: ['Media/Photos'] }, }; } closeAll() {} } """.replace("__FOLDER__", LONG_FOLDER) PROBE = """
