Per mara: the mirror seeding belongs in hive-c0re's forge provisioning
sweep, where the core admin token + org-ensure already live — not a parallel
host-side nix oneshot.
- forge.rs: ensure_mirrors() reads HYPERHIVE_FORGE_MIRRORS (JSON list of
{upstream,dest}), ensures each dest org (reuse ensure_org) + creates the
pull-mirror via the migrate API (reuse forge_http, serde_json::json! body,
409/existing = success). Called in ensure_all() right after the SEEDED_ORGS
loop (token in scope, warn-and-continue like the other ensure_* steps).
- hive-forge.nix: forward effectiveMirrors to c0re via
systemd.services.hive-c0re.environment.HYPERHIVE_FORGE_MIRRORS; drop the
forgejo-seed-mirrors.service + its script + the host-side core-token read.
Keep the forge.mirrors option, DEFAULT_ACTIONS_URL=self (CI-gated), and the
dest-shape / no-c0re-namespace-collision assertions.
Verified locally: nix parse + treefmt (incl rustfmt) clean; serde/serde_json
patterns mirror dashboard.rs. cargo build runs in CI (no cc in my container).
