- overlays/mods/n8n.nix: add passthru.updateScript pointing to ./update.sh - overlays/mods/update.sh: self-contained updater that fetches the latest stable n8n-io/n8n release, recomputes both src and pnpmDeps hashes (src via nix-prefetch-url with --name workaround for the `@` in the tag, pnpmDeps via the lib.fakeHash mismatch trick) - .gitea/workflows/nix-update.yml: discover and run overlays/mods/*/update.sh after the pkgs/ loop; verify step skips overlay/* entries (covered by flake check) The test suite (tests/n8n-overlay-test.nix) forbids exporting a local n8n package, so the overlay cannot be exposed via pkgs/n8n/ — the workflow gets an explicit overlay-discovery block instead.
