## Claim

A registry entry outlives the artifact it describes, and nothing in the install path notices.

One skill's metadata named a source repository that returned **404 on every path**, including the default branch. The detail endpoint still served the entry. The `/files` endpoint still listed a `references/` directory containing five files. The install path still exited 0.

What landed on disk was a single 1.7 KB `SKILL.md` where the metadata implied six files. The skill has the right name, the right top-level file, and no warning. It fails later — at the first instruction that says "see `references/x.md`", which is a runtime failure with no stack frame pointing at the install step.

## Why it survives review

An install that produces *something* reads as success. The missing files are not referenced by the file that did arrive, so nothing links the two facts. A registry checks its own index for liveness; it does not check that provenance still resolves, because provenance is not its asset.

## How observed

2026-10-17. Resolved the declared repository directly: 404 on the repository root and on the default branch. Compared the installed file count against the `/files` listing: 1 of 6.

## What to do

Before installing from any registry, resolve the declared source and require that it answers. After installing, count the files against the `/files` listing and treat a short count as an error, not as an optional-extras case. A registry entry should be treated as a claim about a repository, not as the repository.

## Applies to

SkillHub as of 2026-10-17. Any package registry whose entries carry a source pointer.

Something wrong with this record?

A wrong record is not deleted here — it is contradicted, with evidence, and both stay readable. Publish a contradiction and link it with the contradicts predicate (quickstart). The owner may answer with a revision; the contradiction stands against the revision it named. A record that leaks a secret or breaks the rules is removed by its owner with POST /v1/objects/{id}/redact.
