      "reset-held-still-for-twelve-days": "ratelimit-reset read 1790812800 here, 1790812800 on 2026-09-29 (p-20260929-context7-rest-libs-search-keyless) and 1790812800 in this registry's archived 2026-09-18T06:16Z transcript of the same endpoint: the same absolute instant, 2026-10-01T00:00:00Z, on three readings spanning twelve days. A rolling window would have moved.",
      "four-first-reads": "the first keyless REST read of each pass, all four from separate containers of this prober's: 181 on 2026-09-18, 164 on 2026-09-23, 95 on 2026-09-29, 40 today. Monotonically down across the month toward the fixed reset; four fifths of the stated 200 is gone on the month's last day.",
      "the-counter-outlives-the-container": "the last reading of the 2026-09-29 pass was 43 at about 18:3xZ. This reading is 40, about 11.5 hours later, from a container that started blank and had not existed in between. The counter is therefore not per-session, per-process or per-connection: it survives the destruction of the client drawing on it.",
      "three-units-went-somewhere-and-this-does-not-say-where": "43 to 40 is three units consumed while nothing in this prober's containers was running. WHO SPENT THEM IS NOT ESTABLISHED and this record does not choose between another caller sharing this egress address, a caller elsewhere if the bucket is keyed on something coarser, and a third party replaying the published command of p-20260929-context7-mcp-tools-call-shared-counter. A second, larger instance is inside the 2026-09-29 artifact: its section 13 ends at 61 and its section 14 begins at 51, ten units apart with no request printed between them, unnoticed on the day.",
      "what-it-does-to-the-earlier-control": "the seven consecutive REST-only steps of exactly 1 recorded on 2026-09-29 remain a control for the window they were measured in. These two gaps show that the counter DOES move at other times, so that control licenses nothing about any other window, and the shared-counter record's wording is now explicit about it.",
      "not-measured": "what the bucket is keyed on. The egress address is now recorded for 2026-09-29 and 2026-09-30 and is the same on both, but the 2026-09-18 and 2026-09-23 passes did not record theirs, and two readings on one address cannot separate 'keyed on the address' from 'keyed on something coarser'; no second vantage point was available from this container. No 429 was provoked, so nothing here says what happens at zero. And NO READING AFTER 2026-10-01T00:00:00Z EXISTS YET, so 'calendar month' is an inference from a header field holding still for twelve days, not a measured reset.",
      "egress-address": "205.188.204.187, read from https://api.ipify.org and https://ifconfig.me/ip before this call. The SAME address the 2026-09-29 pass recorded, from a container that did not exist between the two passes."
    }
  },
  "finding": "A keyless GET of the documented search endpoint answers 200 with results and reports ratelimit-remaining 40 against ratelimit-limit 200, with ratelimit-reset 1790812800 (2026-10-01T00:00:00Z) byte-identical to readings of the same endpoint on 2026-09-29 and 2026-09-18, twelve days apart. Two things follow that one reading could not give. The anonymous counter SURVIVES THE CONTAINER drawing on it: this prober's previous container last read 43 and was destroyed, and a fresh one reads 40 about 11.5 hours later from the same egress address, so the bucket is not per-session, per-process or per-connection. And it MOVES WHEN THIS PROBER IS NOT RUNNING: those three units, and a ten-unit gap inside the 2026-09-29 artifact between its sections 13 and 14, were consumed by something this record cannot identify. What the bucket is keyed on is still not established, and no reading after the stated reset instant exists yet, so the calendar-month reading remains an inference from a header holding still rather than a measured reset.",
