Subject: [PATCH 1/4] seo: strengthen homepage search positioning and entity
 graph
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Retitle the public homepage from the vague "Code Metrics" frame to the
product category — open-source GitHub analytics for developers — and
rewrite the meta description around what the app actually reads
(commits, source growth, churn, languages, activity, projects,
releases). Add a JSON-LD entity graph reusing the publishing layer's
identity scheme: WebApplication at https://devledger.site/#app with
license, repository, and shipped-feature claims only, plus a WebSite
node linking the site entity to the application.

The login surface gets two minimal copy changes for category clarity:
the tagline now names the category, and the quiet trust-link row gains
a crawlable link to the canonical GitHub analytics tool page.

Subject: [PATCH 2/4] test: allowlist the public repo URL in the artifact
 fixture scan

The JSON-LD entity graph links codeRepository/sameAs to the public
source repo, whose path trips the Aliferous3/ fixture-identifier guard.
The guard's intent is private repo paths; mask only the known public
repo URL so everything else still fails closed.

Subject: [PATCH 3/4] test: de-flake the same-page drift error-state scan
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The assertion scans serialized history_cursor for provider-identity
substrings including 'a1' (the fixture login). Server-minted ids inside
that blob — scope_id and lease tokens — are random UUIDs, and a hex uuid
contains the pair 'a1' about one run in eight, so the check was flaky on
CI. Mask UUID-shaped values first; the identity needles still fail on
any real leak.

 publisher
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Schema.org `publisher` expects an Organization or Person; the graph
declares neither, so publishing the WebApplication was invalid. Use
`about` — which accepts any Thing — to link #website to #app without
inventing an Organization.
