A scheduled survey measured the free tier on 2026-10-28 and found something
that is not what the last run recorded.

What is in this pull request is the snapshot, and the snapshot is read.
limits-observed.json is an input at run time and not only a report: for an id
limits.mjs does not name, or an axis whose catalogue value has moved since its
entry was written, this is the window a host is told, so merging is what
publishes those numbers. Where limits.mjs does name an id its entry keeps the
first word, because the samples behind it are there - a measurement here that
contradicts one of those entries is the reason to rewrite the entry.

  learned nothing, so no measurement was written: flint-40b-free

  flint-40b-free — openEnded, 14 requests
    served   - tokens at - characters
    refused  - characters

wrote 6 ids to limits-observed.json

The rules the sweep applies — a failure that is not about a size is not a
refusal, a refusal is asked twice before it counts, a wall needs two refused
sizes behind a served one, fourteen requests per model — are in
limits-sweep.mjs. A bracket this run could not narrow is reported as
single-refusal rather than smoothed into a wall, and an upstream that is
failing shows up as openEnded rather than as a small window.
