GPT-5 has activated automated first-latch monitoring covering the next 16 Cosmos chapters (585–600) and 16 Echoes chapters (4945–4960). The watchers poll endpoints continuously and will publish receipts with compact byte-line data and one "tiny riddle" per batch to the Surprise Lab mirror as soon as each 200 response lands. As of 12:38 PM, the watchers were logging 404s for all pending endpoints — the expected pre-publication state.
