AGENTS.md: allow official upstream mirrors as source_provenance (glib, libxml2, libxslt) - #987
Conversation
…, libxml2, libxslt) The never-a-mirror rule had three precedent exceptions with no policy behind them. Add a narrow one: upstream-run mirror, same tags at the same SHAs, and needed for advisory/CPE coverage (the scanner's GitLab path drops the curated CPE identity). Sunsets when supply-chain's GitLab path consults it too. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

- Around line 345-347: Update the AGENTS.md provenance guidance to remove glib
from the current GithubRepo exception list, since it has no source_provenance
block, and add explanatory comments beside the existing source_provenance blocks
for libxml2 and libxslt.

Approving. The exception is reasonably narrow: GitHub only, three named packages, and a sunset. I'm leaving the wording to your judgement, with these suggestions:
Worth fixing
- The comment requirement isn't met yet. AGENTS.md:345 requires a comment beside the provenance block, but
libxml2/build.ncl:56-60andlibxslt/build.ncl:51-55have none, and glib's comes in #918 citing the audit. Adding the one-liners here would keep all three compliant on merge. - The sunset (346-347) points at
'Gitlabwithhost = "gitlab.gnome.org". The section doesn't document that variant (it lists only'GithubRepoand'GnuProject), and no package uses a non-gitlab.com host. - Link the end condition ("minimal-supply-chain's GitLab path") to gominimal/pkgmgr-rs#1029 so it can be checked.
Optional tightening
- "Runs or acknowledges … or its docs link it" would admit a third-party mirror the docs merely link. "Lives in an org/account the upstream project controls" is tighter.
- Say whether adding a fourth package needs an update to this section.
- Say whether this covers
source_provenanceonly, or theSourceurl too. libxml2 and libxslt fetch from the mirror; glib doesn't. - Placement: it reads better after the variant examples.

…ment the three users Review follow-ups: the mirror must live in an org the upstream controls; the exception covers source_provenance only; a fourth package updates the list; the end condition links pkgmgr-rs#1029; the 'Gitlab + host variant is documented beside the others and the exception moves after them. libxml2/libxslt gain the required comment and glib's cites this section (comment-only: 0 spec-hash changes on amd64/arm64).

Thanks @norrietaylor. Everything is addressed in 2b70031, on top of a merge of main (7ff8dcc), which brings in #918. Worth fixing
Optional tightening (all taken)
CodeRabbit's thread (align the exception list with the recipes): at this head glib does have the provenance block, since #918 merged, so all three names stay, and all three now carry the comment. 🤖 Generated with Claude Code |
Follow-up from review on #918: put the official-mirror provenance case into policy rather than precedent.
AGENTS.mdsays never to pointsource_provenanceat a mirror. Three packages do anyway, for a reason the policy doesn't cover:libxml2andlibxsltdeclare'GithubRepo GNOME/<repo>today;glib.GNOME develops on gitlab.gnome.org and publishes the GitHub mirrors itself.
This adds a narrow exception under the existing rule. An official upstream mirror may be declared when:
Why coverage depends on it: the scanner's GitHub path keeps a package's curated CPE identity (e.g.
gnome:glib). Its GitLab path consults the curated identity only when the GitLab identity holds no advisories at all, so a'Gitlab host = "gitlab.gnome.org"provenance can drop NVD-CPE coverage.The text names the three packages, asks for a comment beside each provenance block, and states the sunset: once minimal-supply-chain's GitLab path also consults the curated CPE identity, they move to
'Gitlab.Docs only, no spec-hash changes. glib's
build.ncl:70comment, which currently cites the audit, will be repointed at this section in a follow-up after #918 merges.🤖 Generated with Claude Code
Summary by CodeRabbit
glib,libxml2, andlibxslt, plus guidance to switch to the canonical GitLab source when curated identity coverage is available. This provides clearer direction for current and future package source declarations.
