thirteen chain RPC pages that nobody read and nothing points at

Retired: celo, taiko, kaia, bob, bitlayer, gravity, axelar, hedera,
litecoin, soneium, zircuit, merlin, comdex. Each URL answers 410 Gone.

The test was reach, not data. Between 2026-09-20 (when PostHog starts)
and 2026-11-06, none of the thirteen had a single human visitor: a
device that clicked, viewed two pages or stayed over ten seconds. Plain
visitor counts said otherwise (1 to 18 each), but those were crawlers
that run JavaScript: no clicks, one page on the whole site, 800 px
screens, Santa Clara and Beijing. Our own device is excluded.

Then the second condition, that nothing outside the site points at
them, checked against every PR and issue we have opened elsewhere:

refused celo, taiko, kaia, bob, bitlayer, gravity, axelar, hedera,
litecoin: a docs PR linking the page was closed unmerged
no venue soneium, zircuit, merlin, comdex: no public docs repo and no
issue tracker where a docs request belongs (comdex's org has
not pushed since 2025-01)

The other pages in the zero-visitor set stay: 9 got a docs PR today, 14
an issue asking for the link, and 40 older PRs were followed up.

The probes were healthy (gravity aside, silent since 11-05), so this is
a decision about which pages earn a URL, not a data fix. Specs and
rpc-capabilities harness entries go. The chains stay in the registry
wherever another bench measures them; bitlayer, merlin and comdex had
nothing else and leave it, as the six of #2784 did. The speedtest
directory loses celo, taiko and soneium.

All four cache keys move (bench-unfiltered-v187, all-benchmarks-v180,
bench-filters-v105, providers-v61) and the provider-set guard is
re-pinned, because every cached entry still carries these rows.
