You are running an ebuild from the stuff overlay whose patch tarballs
are now fetched from a sister GitHub repository, "extra-stuff"
(https://github.com/istitov/extra-stuff), instead of being shipped
in the overlay's own files/ tree.

== Why ==

A handful of packages in the stuff overlay carry substantial patches:

  * sys-kernel/pf-sources -r70 ebuilds — a curated subset of
    natalenko's pf-kernel patchset, ~150 KiB to ~1 MiB per slot.
  * sys-kernel/pf-sources orphan-slot -r70 + -r1 ebuilds — a per-slot
    snapshot of alicef's genpatches trunk dir, ~700 KiB to ~1.1 MiB
    per slot. The trunk dir at dev.gentoo.org is a live working
    directory, not a release archive; the snapshot pins immutable
    bytes for these branches.
  * sci-visualization/gwyddion3-3.9-r1 — three pygwy stage patches
    (~600 KiB uncompressed).

Hosting these in the overlay's files/ tree pushed pkgcheck size
limits and bloated every clone. Bundled as tarballs on extra-stuff
and pinned to immutable git tags, they are fetched on demand at
emerge time.

== No user action required ==

extra-stuff is purely a distfile host — it is NOT a Gentoo overlay.
You do not need to register it with eselect repository. Portage
fetches the tarballs as part of the normal install flow, and
verifies them against BLAKE2B + SHA512 hashes pinned in each
affected package's Manifest. If extra-stuff bytes ever changed in
place, the hash mismatch would block the install.

== Bumping patches ==

Tarball revisions are tagged with a numeric suffix (-r70-0 today,
-r70-1 next time, ...). When a tarball's contents need to change,
the new bundle is published under a new tag and the affected
ebuild's SRC_URI is updated to point to it. Older tarballs stay
reachable for users still on older ebuild revisions.
