Cooldown filtering only ran when rewriting metadata, so a version could
be missing from the npm packument and the PyPI simple index while its
tarball stayed reachable. Lockfiles record artifact URLs verbatim, so
npm ci and pinned pip requirements reach handleDownload without ever
requesting metadata.
The shared artifact path has no publish time to check against, since
updateCacheDB upserts versions without PublishedAt and the column is
only set by enrichment. Each handler now resolves the publish time from
metadata it already fetches and returns 404 while a version is inside
the window. Versions with no usable publish time are still served, as
they are when filtering metadata.
* resolve name and version for PEP 658 metadata sidecars
* fix(pypi): parse Windows installer and egg filenames separately
The bdist_wininst and bdist_msi layout joins the platform to the version
with a '.' rather than a '-', so treating .exe/.msi like a wheel folded
the platform into the version: foo-1.0.win32-py2.0.exe resolved to
version "1.0.win32". Eggs shared the problem, as setuptools' hyphen
escaping is not universal: aws-sdk-1.0.0-py3.11.egg resolved to name
"aws", version "sdk".
Give each format its own parser. Wheels keep the PEP 427
spec-guaranteed field positions, eggs locate the version relative to the
py{X.Y} interpreter field, and Windows installers strip the platform and
interpreter fields before splitting name from version.
A PEP 658 sidecar resolves to the same name and version as the
distribution it describes, so it is cached under that version. Browse and
compare took the first cached artifact without checking its extension,
handing openArchive plain text: a version pip had only fetched metadata
for reported hasCached and then 500'd.
Add firstBrowsableArtifact, replacing five duplicated selection loops,
and export PyPIMetadataSuffix so the suffix has a single definition.

- Bump github.com/git-pkgs/registries to v0.6.0: the fetcher now
honours HTTP_PROXY, gates dialled IPs against the safehttp block
list, and Version.Integrity is populated for pub, julia and nuget
- Replace internal/cooldown with github.com/git-pkgs/cooldown v0.1.1
(identical surface, lifted from this repo)
- Update docs/architecture.md to point at the external package
Adds regression test for the PyPI double-packages bug fixed in #50,
and adds fetchedURL assertions to every ecosystem that constructs
upstream download URLs (Conda, CRAN, Maven, NuGet, Conan, Debian, RPM).
Hides package versions published too recently from metadata responses,
giving the community time to spot malicious releases. Configurable
per-ecosystem and per-package with duration overrides. Supported for
npm, PyPI, pub.dev, and Composer.
