Subject: [PATCH] test/e2e: drive the anonymous repo page, public and private
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The API half of val/10-anonpull is covered by the auth matrix. This covers what
Go tests structurally cannot see: whether a logged-out repo page renders, 500s,
or comes back as a blank panel.

Public hold, logged out: 200, all four tags render, and the digest on the page
matches what the registry serves for the selected tag. That last check compares
against whichever tag is selected rather than a hardcoded one, because the page
renders the selected tag's digest and a hardcoded comparison silently fails
whenever the default changes.

Three instrument bugs are baked into the script as comments, because each of
them produced a confident wrong answer first:

  * The repo page is /r/{handle}/*, not /{handle}/{repo}. The latter is a 404
    "Lost at Sea" page, which reads exactly like a denial if you don't check.
  * Tags are <option>s in a <select>. Scraping a,td,span finds nothing and
    reports "no tags" on a page that is rendering them correctly.
  * Logged-out checks use a throwaway persistent profile. A plain
    chromium.launch() does not complete its handshake here, and clearing the
    shared profile's cookies would cost an interactive re-login.

Private hold, logged out: the plan expects a denial. It is not what happens —
the page returns 200 with every tag listed while /v2/ refuses the same repo
with 401 for the same caller. Recorded as a documented divergence rather than
asserted as a failure: the manifest records are world-readable in the user's
PDS by design, so nothing secret is exposed, and /r/ has used OptionalAuth
since before validate-base with the page never consulting captain.Public. The
two read paths simply disagree, and that predates this range.

+// Go tests cover NarrowToPullOnly and the auth matrix covers the API. What
+// neither can see is the class of bug this batch is most likely to produce in
+// the UI: a logged-out repo page that 500s, renders as a blank panel, or
+// renders as a cheerful empty state that looks like "no tags" rather than
+// "you may not see this".
+//
+// Logged-out checks run in an EPHEMERAL context, not the persistent profile in

+// interactive re-login for everything else.
+//
