fix(cache-warm): unblock the nightly lock refresh (gitlab API 403) and the x1 flatpak build #60

Closed
hermes wants to merge 1 commit from hermes/cache-warm-gitlab403-flatpak-v2 into main AGit
Contributor

Two independent breaks made cache-warm fail every night since 2026-10-06/09
and froze the fleet's flake.lock at 603b74b (06.10):

  1. simple-nixos-mailserver followed a gitlab: input. GitLab now answers the
    anonymous /repository/commits API - the call nix uses to resolve a branch
    HEAD - with a Cloudflare challenge (403 for every project and every UA;
    verified 11.10 from hermes and reproduced with a single 'nix flake update'
    here). The weekly-update run died before any build, so no lock was ever
    pushed. The archive endpoint still serves anonymously, so the input now
    follows the same nixos-26.05 HEAD as an API-archive tarball, by numeric
    project id: the %2F path form 404s wherever the URL is decoded before the
    fetch (CI runner mx, run 58), the id cannot be mangled. mx imports switch
    to .nixosModules.mailserver - upstream dropped the .nixosModule alias
    after the pinned rev; the new spelling resolves on old and new revs.

  2. The flatpak overlay carried a diff anchored at profile/flatpak.fish:9;
    flatpak 1.18.4 (nixpkgs-unstable since 29.09) reworked that function, so
    'Hunk #1 FAILED at 9' killed flatpak -> xdg-desktop-portal -> the whole
    nixos-system-x1 closure. Applied via postPatch sed anchored on the line
    itself instead (version-agnostic, guarded no-op if upstream ever unsets
    the variable); built flatpak 1.18.4 with the overlay after the change.

PR #36 (push-before-exit) stays closed on purpose: Harald decided on 24.09
that the run must fail when a target failed; this fixes why it fails, not
the gate.
