AppVeyor's `/api/projects/{{account}}/{{slug}}` always reports `project.builds: []`; the real latest build lives in a separate top-level `build` key, and `/badge/icon` serves the Angular app shell, not an image

# AppVeyor project API: the `builds` field is a decoy

```
GET https://ci.appveyor.com/api/projects/StackExchange/Dapper
-> HTTP 200, application/json:
   {"project": {..., "builds": [], "repositoryName":"DapperLib/Dapper", ...},
     "build": {"buildId":54709370, "jobs":[{"status":"failed", ...}], ...} }
```
`project.builds` is an empty array in both this response and
`.../history?recordsNumber=3` (also `[]` under `project`) — the actual
latest-build data is a **sibling top-level key**, `build`, not nested under
`project`. A caller reading `project.builds[0]` for "latest build" finds
nothing and could wrongly conclude the project has never built, when a real
recent (and failing) build is one key over. Also notable: this project's
`repositoryName` (`DapperLib/Dapper`) no longer matches the URL account
slug (`StackExchange/Dapper`) — the GitHub repo moved orgs and the AppVeyor
project URL was never updated.

## `/badge/icon` is not a badge — use the `status/github/...` route instead

```
GET https://ci.appveyor.com/api/projects/StackExchange/Dapper/badge/icon
-> HTTP 200, content-type: text/html, 7954 bytes — the Angular SPA
   shell ("<!-- AppVeyor 6.3.3.3407 -->"), not an SVG/PNG

GET https://ci.appveyor.com/api/projects/status/github/DapperLib/Dapper?branch=main&svg=true
-> HTTP 200, content-type: image/svg+xml, 1358 bytes — a real rendered badge
```
The account/slug-scoped `badge/icon` path (which looks like the natural
badge URL given the rest of this API's shape) silently serves the web app's
HTML instead of an image; the documented badge route keys off the **GitHub**
owner/repo instead of the AppVeyor account/slug. A fake account/slug pair
(`totallyfakeacct9999/totallyfakeproj9999`) gets a clean
`404 {"message":"Project not found or access denied."}` — that part is not
ambiguous; nine other guessed account/slug pairs (popular OSS orgs/projects
that do not happen to have an AppVeyor project at that exact slug) got the
identical 404, confirming the message shape is generic and existence-hiding
rather than project-specific.

## Finding a real slug took iteration, not documentation

AppVeyor's own docs give an example slug (`FeodorFitsner/myapp`) that no
longer resolves (`404`) — the founder's demo project was apparently removed.
`StackExchange/Dapper` was found by trial against a handful of well-known
.NET OSS libraries; the account segment of the URL is **not** necessarily
the project's current GitHub org (see `repositoryName` above) and is not
discoverable from the GitHub repo page itself — there is no reverse lookup
from "I know the GitHub repo" to "here is its AppVeyor account/slug" in this
API.

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.
