TL;DR

Requesting /zh/tool/ on 2026-09-14 still 308s to the English tool URL. That hop is the AI visibility multilingual finding we can replay.

Direct answer: Treat AI visibility multilingual as locale-locked prompts plus locale-locked pages. On 2026-09-14, /zh answered 308 to /. /zh/tool/perplexity-search-rank-tracking-tools answered 308 to the English tool. The English tool answered 200 with html lang="en" and no hreflang. IANA’s language-subtag registry answered 200 with File-Date: 2026-08-08. No native engine panel was run.

An AI visibility multilingual study that translates an English log after the fact is not a second-surface test. The page never existed in that locale.

What locale parity records

Key definition: AI visibility multilingual means one intent card × one locale tag × one page that actually serves that locale. A translated spreadsheet is not a locale. A 308 to English is a hop, not a Chinese page.

People open AI visibility multilingual after a teammate pastes an English answer under a zh-Hans label. That row is mislabeled. Write the URL that returned HTML, the lang attribute, and the first status.

Managing Multi-Regional and Multilingual Sites is Google’s internationalization guide. We fetched it (HTTP 200). It does not make /zh/tool/ a Chinese document.

SEO Health is the deterministic evidence foundation for hop and HTML reads. A later InfiniSynapse Server API long-task workspace can review a native pack through SSE /api/ai/events; the API does not invent a locale that 308s away.

zh-Hans and zh-Hant stay split

Script, terminology, and target URLs can differ. AI visibility multilingual that collapses them into “Chinese” hides the hop we already have: this host does not serve /zh/tool/ HTML.

W3C choosing a language tag is why we write tags, not adjectives. IANA language-subtag registry answered 200 (731,799 bytes) with File-Date 2026-08-08. That date is the registry’s, not a page translation date.

html lang is a field

MDN lang attribute is the attribute we read. Eight tool pages in this cluster rendered lang="en" and empty hreflang. AI visibility multilingual that assumes hidden Chinese alternates is guessing.

Hops we recorded on this host

User-agent InfiniSynapse-SH1-desk/2026-09-14.

Figure: Two 308s and one 200. hreflang count is zero on the English tool.

Unicode locale data and the Unicode Standard are locale-data references. They do not serve a /zh article. W3C i18n checker is a checker we did not run against production in this desk; say so.

Content-Language was not the story

MDN Content-Language describes a header. The hop table used Location, not Content-Language. AI visibility multilingual notes that invent a Chinese Content-Language on a 308 are fabricating headers.

W3C why declare language is the declaration rationale. Declaration still needs a document.

How to reproduce the 308s

curl -sSI -A 'InfiniSynapse-SH1-desk/2026-09-14' \
  https://infinisynapse.com/zh/tool/perplexity-search-rank-tracking-tools
# location: /en/tool/perplexity-search-rank-tracking-tools

Follow or do not follow; record both. AI visibility multilingual reproduction that only GETs /en will miss the hop.

Package infinitegrowth@0.1.1; -V printed 0.1.0. No aivisibility credit was spent on a Chinese URL, because the Chinese tool URL never returned HTML.

What a later native panel still needs

Native writers for each tag. Intent cards, not literal translations. Locale-specific aliases. Local reviewers. Original-language answers as the stored evidence. AI visibility multilingual fails when an English gloss becomes the record.

Feature availability is a row

A surface can be missing in a market. Record available / unavailable / unknown. Do not average that into a blended “Asia score.”

Sample-size limit

Three requests cannot establish how engines treat Chinese queries, and they do not prove a translated prompt would have landed on a page that 308s. As of 2026 this host’s /zh/tool/ path is a redirect, not a customer locale export.

Failure modes that fake a second language

308 as a translated page. Location points at English.

Empty hreflang as “all locales.” We counted zero. A response that names alternates and still 308s is a different ticket: empty hreflang versus a hreflang pair.

Literal English prompt as native intent. Vocabulary shifts.

IANA File-Date as our publish date. 2026-08-08 is the registry’s.

Unauthorized CLI as a locale block. Login failed elsewhere; this page’s finding is the hop.

Teaching locale grid. Older drafts invented city rows. They are gone.

An AI visibility multilingual memo that skips the Location header is already late.

How a reviewer should read the hop table

Start with /zh. It 308s to /. The homepage is English. Do not label that request as a Chinese article. AI visibility multilingual that files /zh under zh-Hans HTML is misfiling a redirect.

Read /zh/tool/{slug} next. Location points at /en/tool/{slug}. The English tool is the document. html lang is en. hreflang is empty. There is no hidden Chinese alternate on that response. If a teammate pasted a machine translation into a ticket, that paste is not the page.

Read /en/tool/{slug} third. 200 is expected. Use it as the control, not as proof that Chinese exists. Empty hreflang means we did not advertise alternates. Do not invent them.

IANA File-Date 2026-08-08 belongs in the registry row, not in dateModified for this article. Mixing those dates makes it look like we translated a page in August. We did not.

When a later native panel exists, each locale needs its own prompt file, its own reviewers, and its own URLs that actually return that language. A 308 URL cannot be a target. AI visibility multilingual that aims prompts at a hop will measure the English landing page and call it Chinese.

Feature availability is a separate column. A surface can be missing in a market even when the page is translated. Record unknown when you did not check. Do not average unknown into an “Asia score.”

If you only have the three hops, you have the desk. That is enough to reject a translated-log slide. It is not enough to claim engine parity. Write both. A later native panel is an addendum with named reviewers. Do not put invented city rows back into the main table.

Two people repeating the three HEAD requests should see the same Location class unless next.config changed. Store the user-agent. AI visibility multilingual that follows redirects and only prints the final 200 will hide the hop that is the finding.

zh-Hans and zh-Hant remain split even after a future /zh page exists. Script and market vocabulary differ. This desk never reached that future page. The honest sentence is still the 308.

What stays on disk after this desk

Keep the three response headers, a copy of llms.txt if you need product-language context, and the IANA File-Date line. That is the 2026-09-14 AI visibility multilingual packet. Do not add a machine-translated article and label it /zh.

Save next.config redirect intent as a note if you can quote the rule without inventing one. The observed object is still Location. Config commentary is secondary. AI visibility multilingual that quotes config and skips Location will lose the replay.

If a future deploy serves Chinese HTML at /zh/tool/, start a new desk. Re-run the three requests. Store lang, hreflang, and title language. Do not edit the 308 table to look like that future already happened.

Native panels, when they exist, get one folder per tag: prompts, reviewers, original-language answers. English glosses are optional attachments. They are not the record. AI visibility multilingual that stores only glosses will be re-translated by the next analyst.

Feature-availability checks belong in their own CSV: date, tag, surface, available/unavailable/unknown. Do not average them into the hop table.

The decision this page supports is routing honesty. It does not decide whether to hire translators. When someone asks for “Chinese AI visibility,” point at the 308 and stop. Empty native folders are allowed. Fake zh-Hans HTML is not. That stop is AI visibility multilingual on this host.

Package pin 0.1.1 / binary 0.1.0 goes in versions.txt. We did not point aivisibility at a Chinese tool URL, because that URL did not return HTML.

Write the hop in the ticket subject

Subject lines that say “Chinese visibility” hide the 308. Use “/zh/tool/ 308 → English tool” instead. AI visibility multilingual tickets with vague subjects get filled with translations of the English page.

If marketing wants a Chinese URL for a campaign, the work is a locale document, not a prompt translation. Until that document exists, do not aim native prompts at a hop. You will measure English and label it Chinese.

IANA’s File-Date can be copied as a footnote. It must not replace dateVerified on this article. Mixing those dates is how AI visibility multilingual reports start claiming we “updated Chinese” in August.

A second reviewer should HEAD the three URLs before any panel is scheduled. If the 308 is gone, start a new desk. If it remains, cancel the panel or retarget URLs that actually return the locale. That cancel is a success for AI visibility multilingual, not a delay.

Frequently Asked Questions

Why not translate one English prompt literally?

Literal translation can distort local intent. AI visibility multilingual wants a native intent card, and it also wants a page that exists.

Are zh-Hans and zh-Hant one locale?

No. This host does not even serve /zh/tool/ HTML. Splitting scripts still matters for a later panel.

Can an English translation serve as stored evidence?

It may accompany a record. The hop and the original-language HTML remain authoritative.

Were multilingual engine rows collected?

No. The desk is three requests plus the IANA File-Date. That cannot establish engine parity.

How should locale gaps be reported?

Separate hop gaps, page-language gaps, alias gaps, and feature availability. AI visibility multilingual writes the hop first here.

Conclusion

Use AI visibility multilingual when the job is to refuse a translated log until the URL that returned HTML is written down. This 2026-09-14 pass recorded two 308s, one English 200, empty hreflang, and IANA File-Date 2026-08-08. Stop when those Location lines remain visible. A bounded hop table beats an unsupported native-intent grid.

Until /zh/tool/ serves Chinese HTML, treat the locale hop as the finding and stop. That sentence is the whole AI visibility multilingual desk on this host. If a later deploy removes the 308, start a new dated packet: lang, hreflang, title language, and whether the body is actually Chinese. Do not edit the 2026-09-14 Location lines to match that future. The hop remains the historical finding even after the hop is gone. Native panels wait until a URL returns the locale they claim to measure. Anything else is an English measurement with a Chinese label. Write that risk on the first line of any panel brief so AI visibility multilingual does not start from a hop. If the brief cannot name a 200 URL in the target language, cancel. Cancellation is cheaper than a mislabeled week.
