On section and subcategory pages, every row repeated its use case and current page as tags (and as the label under the name on phones), right under a heading that already said the same thing. They are now hidden in editorial order and shown again when a column sort flattens the groups.
Co-Authored-By: Claude <noreply@anthropic.com>
After sorting by a column, or while a search hid a group, category page group headings stayed hidden, so the header's jump links (and any use-case heading link) pointed at a hidden element and did nothing.

Audits that rename or dissolve a category never added a redirect, which is how the 404s appearing in Search Console traced back to renamed category pages.
Co-Authored-By: Claude <noreply@anthropic.com>
Category pages carried no text of their own beyond the README one-line description, and most meta descriptions fell back to a generic "Explore N curated Python projects" line, which correlated with weak search rankings for category queries. This adds optional per-category intro markdown files rendered under the H1, with the first paragraph used as the meta description and links opening in a new tab, starting with the ORM category.
Co-Authored-By: Claude <noreply@anthropic.com>
Renamed or dissolved category slugs (e.g. /categories/web-servers/rpc/, /categories/code-analysis/code-linters/) returned 404, Search Console lists 7 of them, and each audit re-home was dropping the old URL's ranking.

PR numbers named in chat during a review-prs run should be clickable so the maintainer can open each PR in the browser while deciding on it. Defines the PR link convention once in the intro and uses it at both chat sites: the closing-comment draft label and the final summary table.
Co-Authored-By: Claude <noreply@anthropic.com>
In the last review-prs run, closing comments were posted to GitHub without the maintainer ever seeing their full text - the AskUserQuestion options carried one-line paraphrases and the actual comment bytes first appeared inside the gh pr close --comment command. The old wording ("AskUserQuestion presenting the draft closing comment") was satisfiable by a summary. The Close arm now prints each draft verbatim in chat (fenced block, PR number as label) before the AskUserQuestion, and the step's completion criterion binds every posted comment to be byte-identical to a printed draft or to the maintainer's custom text.

The uv-audit bug has no automatic guard outside the bundled-entry
case, so the hazard has to live in the audit process instead. The
sweep only queries names matching PYPI_NAME_RE, so a display name
with a space is skipped outright; renaming it into a PyPI-shaped name
starts it being queried, which is how 'uv audit' became 'uv-audit'
and picked up an unrelated third-party package by rocshers.
The gotcha tells the auditor to fetch PyPI metadata for any renamed
entry and add a null override when the package isn't the linked
project. It also records two broader checks that were measured
against the full list and rejected, so a future audit doesn't spend
time re-proposing them: the repo-backlink check misses this case
entirely since uv-audit declares no repo URL, as do 26 legitimate
entries, and it flags 10 benign org moves; the name-versus-repo-name
check returns 46 hits that are all legitimate, including uv-build
with the shape identical to uv-audit.
Co-Authored-By: Claude <noreply@anthropic.com>
The uv-audit bug had no automated guard: pypi_name_overrides.json is
a manual registry, so a wrong-package mapping is only caught if
someone already suspects it.
Two broader checks were measured against the real list and rejected.
Checking that PyPI metadata links back to the entry's GitHub repo
would not have caught uv-audit, since that package declares no
home_page or project_urls, landing it in a 26-entry bucket of
packages that simply don't declare a repo (numba, selenium, pyglet,
etc.), plus 10 benign cases of orgs moving or splitting bindings.
Flagging display-name/repo-name mismatches yields 46 hits, all
legitimate python-X-repo-to-X-package pairs, with uv-build sitting
among them despite being a real Astral package with the identical
shape to uv-audit.
What discriminates is the bundled marker itself: a "(part of X)"
entry ships inside something else and has no package of its own, so
the sweep must never query it. This test walks the real README and
requires a null override for every bundled entry whose normalized
name is PyPI-shaped. Verified it fails with exactly the uv-audit
message when that override is removed, and passes with it restored,
across the three current bundled entries with no false positives. It
runs offline, fitting the existing network-less CI.
Co-Authored-By: Claude <noreply@anthropic.com>
Renaming the entry from "uv audit" to "uv-audit" made the name PyPI-shaped: normalize() leaves spaces alone, so "uv audit" failed PYPI_NAME_RE and collect_names skipped it, but "uv-audit" passes, so the next sweep would have queried PyPI for it.
A uv-audit package does exist on PyPI, but it is version 0.1.9 by Alekse Marusich of rocshers, an unrelated third-party tool whose summary ("uv Tool for checking dependencies for vulnerabilities") is close enough to be mistaken for Astral's built-in uv audit subcommand. Without the override the entry would have shown that stranger's download count and lost its Bundled badge.
The sweep now writes uv-audit as NOT_FOUND, which load_downloads skips, so the badge is unaffected.

azure-sdk-for-python and google-cloud-python were rendering "Not on
PyPI", which is misleading. Both do ship on PyPI, just as many
per-service packages (azure-identity, azure-storage-blob,
google-cloud-storage, etc.) rather than under the repo name.
pypi_name_overrides.json already recorded that distinction in its
reason field; those two entries now carry an optional "badge" value
that build.py reads into the PyPI Downloads column. The other sixteen
no-count entries (cpython, renpy, agent skill repos, etc.) keep
"Not on PyPI" since that remains accurate for them.
Co-Authored-By: Claude <noreply@anthropic.com>
django.db.models, geodjango, httpx.URL and uv audit were rendering
"Not on PyPI" alongside eighteen genuinely standalone projects that
simply are not packaged on PyPI, conflating two different reasons for
a missing download count.
These four entries now carry a "(part of X)" description prefix in
README.md, mirroring the existing "(Python standard library)"
convention. build.py reads that prefix into a bundled flag that both
templates render as a "Bundled" badge.
The prefix approach was chosen over a separate data file so README.md
stays the single source of content truth, and over inferring from the
entry name because geodjango is neither dotted nor spaced and would
have been missed. Redundant tail wording was trimmed from the
httpx.URL, geodjango and uv audit descriptions now that the prefix
names the parent.
The new entry format is documented in CONTRIBUTING.md and the
vocabulary in CONTEXT.md.
Co-Authored-By: Claude <noreply@anthropic.com>
Standard-library entries rendered "Not on PyPI" in the PyPI Downloads
column, which read like missing data rather than a deliberate category
— the build already forces downloads to None for them so they never
pick up a same-named PyPI backport. They now render a "Stdlib" badge
instead, while genuine non-PyPI entries keep "Not on PyPI".
The filter tag is renamed to match, so the source-type value, the row
filter tag, and the synthetic category heading all read Stdlib now.
The literal "Built-in" strings scattered through build.py are routed
through the existing BUILTIN_FILTER constant so the label lives in one
place. The category page slug stays "built-in" so the public URL
/categories/built-in/ does not break.

Add a Stability Exceptions section to docs/audit-logs.md documenting
the zensical override (admitted pre-1.0 to displace a dying mkdocs
upstream). Add a matching evidence bullet to CLAUDE.md and AGENTS.md
warning that a download count is not automatically independent demand
when one listed entry depends on another, using mkdocs / mkdocs-material
as the worked example. Both facts were discovered during this sitting
and need to persist so the next audit doesn't rediscover them.
Co-Authored-By: Claude <noreply@anthropic.com>
Material for MkDocs went into maintenance mode on 2025-11-05 and its
own team called upstream mkdocs unmaintained since 2024-08 and a
supply chain risk; the mkdocs repo was last pushed 2025-10-20. Since
mkdocs-material hard-depends on mkdocs, mkdocs' download count is
almost entirely mkdocs-material pulling it in (18,360,677/month vs
mkdocs-material's 18,167,775/month, ~1% delta), so dropping the
redundant direct entry costs little. zensical is a clean replacement
with no mkdocs dependency, built by the same Material for MkDocs
team, at 1,585,786 downloads/month and 5,540 stars, pushed
2026-08-21. Added as a challenger, placed last below pdoc, keeping
the section at 5 of 5. Approved via verdict preview.

The "most diffs sit on stale bases" claim was a one-time artifact of
the shortlist reform, not a durable fact about future PRs. Reworded to

Co-Authored-By: Claude <noreply@anthropic.com>
Two live review-prs runs surfaced fixes:
- Merge conflicts move from the screen-out rules to a local-merge path
in the Merge arm; 7/10 PRs conflicted only from the reform's stale
bases, and one such PR had already been merged this way.
- Target use case is now resolved from the current README instead of
stale diff context, since most PR bases no longer match live
sections.
- Judge gets a third verdict: no fitting use case is a structure
question, carried to Act for the maintainer to decide.
- Act's Close step gets a batching and checklist note, and the whole
step gets an explicit completion criterion after a verdict nearly
fell out of the question batches.
- Drop the "claude reviewed" label mechanism entirely: the fetch
filter, the Park arm, and the labeled-open terminal state.
