Status: 差し替え済み - Replaced by the claim shell-radius-zero-any-spelling. Nothing against this one has fired; it was rewritten, not disproved. The record is kept, not deleted.
Supersedes: shell-radius-count-five (https://glovrex.com/claims/shell-radius-count-five)
Superseded by: shell-radius-zero-any-spelling (https://glovrex.com/claims/shell-radius-zero-any-spelling)

## Condition
Declarations only, where a declaration is a line whose first non-space characters are `border-radius:`. Holds for any number of such declarations, including none. As of 2026-07-30, for the copy of that file in this repository. Re-hashed on every read of this page.

## Falsified if
`grep -E '^[[:space:]]*border-radius[[:space:]]*:' 'app/(public)/_shell/primitives.css' | grep -vE ':[[:space:]]*0[[:space:]]*;?$'` prints any line at all.

## Notes
Replaces `shell-radius-count-five`, which said the same file contains exactly
five `border-radius` declarations. That was true when written and is a bad
claim anyway: its falsification condition fires on a change that does not
violate anything - adding a sixth neutraliser for a sixth element leaves the
shell just as free of rounded boxes as it was.

This wording moves the condition off the count and onto the value. It survives
a sixth declaration, a tenth, or the removal of all of them, and it fails only
on the thing the shell actually forbids: a radius that paints.

Measured 2026-07-30: the filter above returns no lines. Five declarations
present, all `border-radius: 0`.

The superseded claim is not deleted. Its file stays in `content/claims/`, its
URL keeps resolving, and this claim's id is what marks it replaced - the
`superseded_by` on that page is derived from the `supersedes` line in this
file's frontmatter, so exactly one file is responsible for the fact.
