test(cypress): visit the app under appLocation, not the server root

Eight `cy.visit` calls in five specs addressed the app as `${hostUrl}/...` or
`cy.visit(hostUrl)`. That is the address the app had on a dev server, which
served it at the origin root; served by the server it talks to, the app lives
under `appLocation` and the root is not the app, so those visits loaded nothing
the spec could act on and then failed waiting for a grid, a modal or a rendered
state.

Every visit now builds its URL from `hostUrl + appLocation`. The three specs
observed failing in CI pass with it, against the build streamed at
/AppStream/clickme:

  browser-info.cy.ts            3 passing   (#hotTable never found)
  startupservice-launcher.cy.ts 1 passing   (.clr-abort-modal never found)
  deploy-folder-picker.cy.ts    2 passing   (no state to act on)

CI (`.gitea/workflows/build.yaml`) builds the same environment - SASjs Server on :5000, `sasjs cbd -t server-ci` streaming the production build to `/AppStream/clickme`, makedata and createdemodata - and runs a fixed list of specs against the app served from that origin. The suite drives the built artefact, not a dev server, so `hosturl` is `http://localhost:5000` and `appLocation` is `/AppStream/clickme`, both passed as `--env`.
 
 This skill covers the parts that are not obvious from reading a spec file: how to stand the environment up, the selectors that actually work, and the traps in the mock services. It does not cover the SAS-side tests (see `.agents/docs/testing.md` and the `dc-sas` skill).

 ### How the mocks work
 
-Each `.js` file in `sas/mocks/sasjs/services/` corresponds to a real SAS service (e.g. `public/startupservice.js` mimics `services/public/startupservice.sas`). The JS runtime predeclares `fs`, `_program` (the program's deployed path), `weboutPath` (the response body it writes) and `_webout`, and the services emit their members through the runtime's `webout()` - `webout('OPEN')`, one `webout('OBJ', name, rows)` (or `webout('ARR', name, rows)` for positional rows) per member, `webout('CLOSE')` - so the response envelope comes from the host and the file carries only what the SAS service returns. A few services still write the body themselves through `_webout`: the ones that emit plain text, CSV, DDL or HTML and set their own content headers (`admin/exportdb`, `admin/makedata`, `public/getrawdata`, `public/getddl`), and the lineage captures. Some mocks are stateful: they persist data to a `mock-storage/` folder on the SASjs Drive (e.g. `licence.json`, `users.json`, `filter.txt`) using the predeclared `fs` module.
+Each `.js` file in `sas/mocks/sasjs/services/` corresponds to a real SAS service (e.g. `public/startupservice.js` mimics `services/public/startupservice.sas`). `admin/createdemodata.js` is the exception: it has no SAS counterpart, because it exists only to give the test estate tables a deployed site would not have. The JS runtime predeclares `fs`, `_program` (the program's deployed path), `weboutPath` (the response body it writes) and `_webout`, and the services emit their members through the runtime's `webout()` - `webout('OPEN')`, one `webout('OBJ', name, rows)` (or `webout('ARR', name, rows)` for positional rows) per member, `webout('CLOSE')` - so the response envelope comes from the host and the file carries only what the SAS service returns. A few services still write the body themselves through `_webout`: the ones that emit plain text, CSV, DDL, HTML or a file download and set their own content headers (`admin/exportconfig`, `admin/exportdb`, `admin/makedata`, `auditors/getauditfile`, `public/getddl`, `public/getrawdata`). `sas/mocks/test/sasjs-webout.test.js` holds that list, so a service that goes back to writing its own body fails the suite. Some mocks are stateful: they persist data to a `mock-storage/` folder on the SASjs Drive (e.g. `licence.json`, `users.json`, `filter.txt`) using the predeclared `fs` module.
 
-The mock data includes sample tables (`DC996664.MPE_X_TEST`, `MPE_X_NEW`, `MPE_X_FORMULA_TEST`, etc.) with realistic columns, validation rules (HARDREGEX, SOFTREGEX, HARDSELECT, READONLY, HIDDEN, ROUND, NUMBER_FORMAT), and dropdown values. This is sufficient to exercise the full editor grid, approval workflow, viewer, and admin screens.
+`admin/makedata` builds only what the SAS service builds: the control library defined by `mpe_makedatamodel.sas`, seeded with the rows `mpe_makedata.sas` inserts. `sas/mocks/test/makedata-parity.test.js` reads both macros and fails when the mock estate drifts from them, so the mock and a deployed site open with the same tables and the same configuration.
+
+The fixtures the Cypress suite needs but a DC install does not have live in `admin/createdemodata`, which runs after makedata: the `TESTDATA` demo library (`MPE_X_NEW`, `MPE_X_FORMULA_TEST`, `DERIVED_DEMO`, etc.) with its validation rules (HARDREGEX, SOFTREGEX, HARDSELECT, READONLY, HIDDEN, ROUND, NUMBER_FORMAT) and dropdown values, the `MPE_X_SEARCH` and `MPE_X_WIDE` viewer fixtures, and the `DC996664` multi-load library. It is safe to run twice, and refuses to run before makedata.
 
 There is also a SAS 9 mock variant under `sas/mocks/sas9/` (target `sas9-mocks`) that mimics SAS 9 stored processes with the same JS approach but a different appLoc (`/User Folders/sasdemo/`). Its services are fixed recordings of the SAS 9 responses, emitted through `webout()` in the same way; the payloads are the SAS 9 ones (metadata URIs, `BUILTIN\Administrators` owners, `D:\...` paths, with their separators - the front end splits on `\`, so a value that arrives without it exercises the wrong branch). Only the payloads are SAS 9 flavour: the envelope around them (`_PROGRAM`, `SYSUSERID`, `SYSVLONG`, `SYSDATE`/`SYSTIME`) is whatever runtime serves the request, so do not read this variant for SAS 9 envelope values.
