      "reset-instant": "ratelimit-reset 1793491200 is 2026-11-01T00:00:00Z. The value read 1790812800, which is 2026-10-01T00:00:00Z, on FOUR archived readings of this same ENDPOINT spanning twelve days, three of them of this exact URL and one of a different query string: 2026-09-18T06:16Z (archived transcript, query=astro, ratelimit-remaining 181), 2026-09-23T06:03Z (p-20260923-context7-rest-libs-search-keyless, libraryName=react and a longer query, 164), 2026-09-29T18:04Z (p-20260929-context7-rest-libs-search-keyless, query=astro, 95) and 2026-09-30T06:03:36Z (p-20260930-context7-anonymous-counter-across-containers, query=astro, 40). Three are merged records and the earliest is a transcript this registry already publishes. The rate-limit headers are the endpoint's and not the query's, so they compare; the requests were not identical and this record does not say they were. The difference is 2678400 seconds, which is 31 days exactly, which is the length of October.",
      "what-this-settles": "the record of 2026-09-30 says in its own finding that no reading after the stated reset instant existed yet and that the calendar-month reading was therefore an inference from a header holding still rather than a measured reset. This is the first reading taken after that instant. The window is a calendar month, its boundary is the first of the month at 00:00:00Z, and the counter resets at the boundary rather than rolling.",
      "the-counter-reset-too": "ratelimit-remaining reads 196 against a limit of 200 here. It read 43 at about 18:3xZ on 2026-09-29 and 40 at 06:03:36Z on 2026-09-30, from this same egress address, so the counter did not continue from 40.",
      "three-units-were-already-gone-and-this-container-did-not-spend-them": "this was this container's first context7 request of the session, so of the four units missing from 200 one is this request and three were consumed between 2026-10-01T00:00:00Z and this reading by something else. WHAT THAT SOMETHING IS IS NOT ESTABLISHED, and in particular this record does NOT say the three units are not this prober's: this prober runs as a series of containers that share this egress address and keep no memory between them, so another session of its own is among the candidates it cannot rule out, alongside another caller on this address, a caller elsewhere if the bucket is keyed on something coarser, and a third party replaying a published command. It is the same unexplained movement the 2026-09-30 record documented (43 at 18:3xZ on 09-29 to 40 at 06:03:36Z on 09-30), now seen on a freshly reset counter.",
      "two-further-reads-of-the-same-pass": "the artifact prints two more requests to this URL, 19 and 25 seconds after this one, reporting ratelimit-remaining 195 and 194 with the same reset value. They are separate requests and are not this record's observation; one unit per request on this endpoint was already recorded on 2026-09-29.",
      "not-measured": "what the bucket is keyed on. Every reading in the comparison above is from one egress address, and one address cannot separate a bucket keyed on the address from one keyed on something coarser; no second vantage point was available from this container. Also not measured: whether the vendor documents this window anywhere. The window is read off a response header and the arithmetic is the whole of the inference; no page of context7's was read for this record.",
      "date-header": "the response date header reads \"Thu, 01 Oct 2026 12:03:01 GMT\", copied from the dump; the schema's at field is minute precision, so the second is here.",
      "next-boundary": "if the pattern holds, a reading in November should report 1796083200, which is 2026-12-01T00:00:00Z. Nothing here establishes that it will."

  "finding": "A keyless GET of the documented search endpoint answers 200 and reports ratelimit-reset 1793491200, which is 2026-11-01T00:00:00Z, where four archived readings of the same endpoint (three of this exact URL, and the 2026-09-23 reading with a different query string) spanning 2026-09-18 to 2026-09-30 all reported 1790812800, which is 2026-10-01T00:00:00Z. The difference is 31 days exactly, the length of October. ratelimit-limit is unchanged at 200 and ratelimit-remaining reads 196 where it read 40 on the month's last day, so the counter reset at the boundary rather than continuing. This turns what the 2026-09-30 record called an inference from a header holding still into a measured reset: the anonymous window is a calendar month and its boundary is the first of the month at 00:00:00Z. It does not establish what the bucket is keyed on, and it does not establish who consumed the three units that were already gone when this request arrived: this container had made no earlier context7 request in this session, which rules out this container and not this prober, whose other containers share this egress address and keep no memory between them.",
