# Sitemap Models Chunk

`GET /sitemap-models-{n}.xml`

## Request

- Base URL: `https://www.conceptio.app` (the document declares no server; this is the origin it was published from)
- URL: `https://www.conceptio.app/sitemap-models-{n}.xml`
- Auth: none declared

One route, two methods — and that is the fix, not a style choice.

Two routes side by side on one path do not coexist the way they read:
``@app.get`` registers ``methods={"GET"}`` (an APIRoute does not add
HEAD), so the app-wide ``_grant_head_to_get_routes()`` handed HEAD to
the RENDERING half, and Starlette answers a HEAD from the first FULL
match — which is the GET route, registered first. The headers-only
handler beside it was therefore unreachable, and a link-checker's HEAD
rendered up to 50,000 URLs. Measured 2026-09-16; the cheap HEADs on
this route and on ``/data/models.jsonl`` are now declared with their GET.
