Every view below is generated from the same file-cited data source — 45 real services, 17 real control & data paths, traced from the code at latest main across six repos. Each rendering survived because it does a job the other two can't.

why it exists: maximum legibility — you can trace any payload end-to-end in seconds THE SHOWPIECEHarness City Max — 3D night cityThousands of ambient buildings, bloom, glow-sprite payloads — the real services as glowing landmark towers, click-to-inspect.
