 3. Run `Scripts/bootstrap-forge-intake.sh` to place the Forgejo bootstrap password file and automation SSH key under `/var/lib/burrow/intake/`.
 4. Let `burrow-forgejo-bootstrap.service` create or rotate the initial Forgejo admin account.
 5. Let `burrow-forgejo-runner-bootstrap.service` register the self-hosted Forgejo runner and seed Git identity as `agent <agent@burrow.net>`.
-6. Run `Scripts/provision-forgejo-nsc.sh` locally, then `Scripts/sync-forgejo-nsc-config.sh` to place the raw Namespace dispatcher/autoscaler runtime inputs under `/var/lib/burrow/intake/` for the upstream `services.forgejo-nsc` module.
-7. Visit `https://nsc.burrow.net/` as a Burrow admin to link the forge-owned Namespace session and rotate `/var/lib/burrow/intake/forgejo_nsc_token.txt` without relying on a personal local `nsc` login.
-8. Ensure `/var/lib/agenix/agenix.key` exists on the host, encrypt `secrets/infra/authentik.env.age`, `secrets/infra/authentik-google-client-id.age`, `secrets/infra/authentik-google-client-secret.age`, `secrets/infra/forgejo-oidc-client-secret.age`, and `secrets/infra/headscale-oidc-client-secret.age`, and let agenix materialize them under `/run/agenix/`.
-9. Use `Scripts/cloudflare-upsert-a-record.sh` to point `git.burrow.net`, `burrow.net`, `auth.burrow.net`, `ts.burrow.net`, `nsc.burrow.net`, and `nsc-autoscaler.burrow.net` at the host with Cloudflare proxying disabled for ACME.
+6. Run `Scripts/provision-forgejo-nsc.sh` locally to refresh `intake/forgejo_nsc_token.txt`, `intake/forgejo_nsc_dispatcher.yaml`, and `intake/forgejo_nsc_autoscaler.yaml`.
+7. Run `Scripts/seal-forgejo-nsc-secrets.sh` to encrypt those runtime inputs into the agenix secrets used by `burrow-forge`.
+8. Ensure `/var/lib/agenix/agenix.key` exists on the host, encrypt `secrets/infra/authentik.env.age`, `secrets/infra/authentik-google-client-id.age`, `secrets/infra/authentik-google-client-secret.age`, `secrets/infra/forgejo-oidc-client-secret.age`, `secrets/infra/headscale-oidc-client-secret.age`, `secrets/infra/forgejo-nsc-token.age`, `secrets/infra/forgejo-nsc-dispatcher-config.age`, and `secrets/infra/forgejo-nsc-autoscaler-config.age`, and let agenix materialize them under `/run/agenix/`.

 10. Use `Scripts/forge-deploy.sh --allow-dirty` for subsequent remote `nixos-rebuild` runs from the live workspace.
 11. Configure Forward Email custom S3 backups for `burrow.net` and `burrow.rs` out-of-band with `Tools/forwardemail-custom-s3.sh`.
 
 ## Current Constraints
 
-- `burrow-forge` is live on NixOS in `hel1` at `89.167.47.21`, and `Scripts/check-forge-host.sh --expect-nsc` passes locally against that host.
+- `burrow-forge` is live on NixOS in `hel1` at `89.167.47.21`.
+- `services.forgejo-nsc` now expects agenix-backed runtime inputs at `/run/agenix/burrowForgejoNscToken`, `/run/agenix/burrowForgejoNscDispatcherConfig`, and `/run/agenix/burrowForgejoNscAutoscalerConfig`.
 - Authentik and Headscale secrets now live in tracked agenix blobs under `secrets/infra/` and decrypt to `/run/agenix/` on the forge host.
 - Public Burrow forge cutover completed on March 15, 2026:
   - `burrow.net`, `git.burrow.net`, and `nsc-autoscaler.burrow.net` now publish public `A` records to `89.167.47.21`
