+description: >
+  Use this skill when writing or debugging Cypress E2E specs in the dc repo, or when working on the
+  JS mock backend they run against. Covers the SASjs Server mock environment (deploy, seed, ports),
+  the spec conventions the CI harness expects, the viewer/editor DOM selectors that the existing
+  specs get wrong, the fixed 1280x720 video capture, and the rule that a mock service must mirror
+  the real SAS service it stands in for.
+---
+
+# Cypress E2E and the JS mock backend
+
+The specs under `client/cypress/e2e/` run against a mock backend: JS stored programs under `sas/mocks/sasjs/services/` executed by SASjs Server in JS-only mode. No SAS licence, no SAS server. CI (`.gitea/workflows/build.yaml`) builds the same environment - SASjs Server on :5000, `sasjs cbd -t server-ci`, makedata, then `ng serve` on :4200 - and runs a fixed list of specs against it.
+
+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).
+
+## When to Use
+
+- Adding or changing a spec under `client/cypress/e2e/`.
+- A mock service needs a new behaviour, or a spec "does nothing" because the mock ignores an input.
+- Recording a demo video from a spec run.
+- Debugging a spec that passes locally but fails in CI (usually a viewport or timing assumption).
+
+Don't use for: SAS backend tests (`sasjs test -t 4gl`), Angular unit tests (`npm run test:headless`), or general SAS development (use the `dc-sas` skill).
+
+## Stand up the mock environment
+
+1. **SASjs Server, JS mode.** Download the linux build from the sasjs/server releases, then create a `.env` next to the binary:
+
+       RUN_TIMES=js
+       NODE_PATH=node
+       CORS=enable
+       WHITELIST=http://localhost:4200
+
+   Start it (`./api-linux`). It runs in desktop mode on :5000 with no authentication.
+
+2. **Deploy the mocks.**
+
+       cd sas/mocks/sasjs && sasjs cbd -t server-ci
+
+   To start from a clean appLoc, delete it first:
+
+       curl -sS -X DELETE "http://localhost:5000/SASjsApi/drive/folder/?_folderPath=/Public/app/dc"
+
+3. **Seed the mock database.**
+
+       cd sas/mocks && sasjs request services/admin/makedata -t server-ci \
+           -d deploy/makedata.json -o ./makedata_out.json
+
+   `makedata` replies with HTML (it is normally called as a URL redirect), so the CLI reports `invalid Json string`. That is expected - check the drive instead.
+
+4. **Frontend.** Point the `sasjs` tag in `client/src/index.html` at the mock backend (`serverUrl="http://localhost:5000"`, `appLoc="/Public/app/dc"`, `serverType="SASJS"` - a local-only edit, the repo default is `serverUrl=""`), then `npx ng serve --host 0.0.0.0 --port 4200`. `client/cypress.env.json` needs `username`/`password` entries; any values work, `loginAndUpdateValidKey()` no-ops when there is no login form.
+
+5. **Run.**
+
+       cd client && npx cypress run --browser electron --spec cypress/e2e/<spec>.cy.ts
+
+   Only Electron is installed here (no system Chrome), so always pass `--browser electron`.
+
+## Spec conventions
+
+- Start the file with `export {}` so its top-level consts do not collide with other spec files under the TS type-checker.
+- `beforeAll`: `cy.visit(\`${hostUrl}/SASLogon/logout\`)` then `cy.loginAndUpdateValidKey(true)`. The `true` forces a licence key instead of relying on an earlier spec in the same run having applied one.
+- `beforeEach`: `cy.visit(hostUrl + appLocation)`, `visitPage('home')`, `visitPage('view/data')`. The `home` visit is what triggers the startup-data fetch; going straight to `view/data` leaves the nav tree empty in slower environments.
+- Declare helpers at the **bottom of each spec file** (that is the house pattern) - do not introduce a shared helper module.
+- Use `Cypress.env('longerCommandTimeout')` for waits and gate on `.app-loading` disappearing.
+- **No artificial delays.** These specs are the CI regression suite, so `cy.wait(n)` to "let a result land" is not acceptable - assert on the resulting state instead (Cypress retries assertions). Replace a sleep with a state assertion: e.g. after picking an option from a soft-select, wait for `#datalist_<inputId>` to have class `hidden` rather than sleeping.
+- Lint: `cd client && npm run lint:check` (prettier covers `cypress/e2e/*.cy.ts`).
+
+## Selectors that work
+
+- Viewer search box: `input[name="search-input"]` (Enter or the magnifier icon submits); the numeric toggle is `input[name="numeric_check"]`.
+- Row/column count in the header: `.title-col p` renders `(1,000 rows, 9 cols)` - and `(1 row, 9 cols)` when the result is a single row, so an assertion on the count has to pluralise.
+- Filter info bar: `.infoBar b` - only rendered when the backend's `sasparams.FILTER_TEXT` is neither blank, `' '`, nor `'1=1'`.
+- Empty result: `.noData h3` with `No data found with given conditions`.
+- Grid: `#hotTable .ht_master.handsontable .htCore tbody tr` (body rows), `#hotTable .ht_clone_top .htCore thead` (headers, and `button.changeType` confirms Handsontable has finished rendering them).
+- Nav tree: `.nav-tree clr-tree > clr-tree-node` -> `.clr-tree-node-content-container .clr-treenode-content p` (expands a library) -> `.clr-treenode-link` (table links).
+- **Viewer filter modal** - `.filterSide` (the options button) -> `.dropdown-menu` contains `Filter` -> `#vals_var_id0_0` (variable, pick from `#datalist_vals_var_id0_0 option`) and `#vals_0_0` (value) -> `.filter-modal button[aria-label="Ok"]`.
+  - `filtering.cy.ts` opens the filter with `.btnCtrl .btnView`, which is an **editor** control and does not exist in the viewer. Do not copy that helper into a viewer spec.
+  - The soft-select inputs drop a transparent click-catcher over the modal while their suggestion list is open, so Cypress reports the Ok button (and the next input) as covered by `.overlay`. Send the Escape keyup a user would send (`trigger('keyup', { key: 'Escape', force: true })`) and wait for the list to close before clicking on.
+
+## Recording a demo video
+
+`video: true` in `cypress.config.ts` is all that is needed. Run the spec and the MP4 lands in `client/cypress/videos/<spec>.mp4`.
+
+**The capture is the browser window's content area, and it contains the Cypress runner** - the command log takes the left ~450px and the app is rendered in the remaining pane, so the pane is `(capture width - 450) x (capture height - 96)` and the app is zoomed to fit it.
+
+That makes the window size the only lever that matters:
+
+- Electron is stuck at 1280x720 (it ignores `--window-size`), i.e. an 830x624 pane, and the repo's 1600x900 viewport renders at 50% - the app only occupies ~806x452 of it.
+- A real Chromium browser honours `--window-size`, so the capture can be sized to whatever the pane needs. `cypress.config.ts` passes it through from `RECORD_WINDOW_SIZE` (inert in CI, which sets no env).
+
+For a 16:9 pane, solve `(W - 450) / (H - 96) = 16/9`: W = 1920 gives H = 923 of window *content*, and Chrome adds ~87px of window chrome above that, so pass 1920x1010:
+
+    RECORD_WINDOW_SIZE=1920,1010 npx cypress run \
+      --browser /opt/data/profiles/dc/tools/chrome-linux64/chrome \
+      --spec cypress/e2e/full-table-search.cy.ts \
+      --env skipNegative=true,demoPause=1500
+
+That yields a 1920x922 capture with a 1470x826 pane (16:9) and, at the repo's 1600x900 viewport, an app at ~0.90 zoom occupying 1441x812 - about 1.9x the linear size of the 16:9 crop Electron can give. Crop the app out:
+
+    ffmpeg -ss <start> -i cypress/videos/<spec>.mp4 -vf "crop=1440:812:464:80" \
+      -an -c:v libx264 -preset slow -crf 18 -pix_fmt yuv420p \
+      -movflags +faststart <spec>-cut.mp4
+
+Measure the crop rect from the frames rather than guessing: the pane's flat background is rgb(225,227,236), so a row/column scan for pixels that differ from it gives the app's bounding box (for the 1920x922 capture: runner pane ends x=449, app x=463-1903, app y=80-893; for the 1280x720 Electron capture: app x=468-1259, y=80-675). The app's own background is nearly the same grey, so verify the result on the first, middle and last frames rather than trusting a pixel test alone.
+
+To find where to cut, scan the mean *and* standard deviation of the content area: the app boots mid-run (a dark screen, mean ~65, sd ~2.5), the "Loading Table Viewer" spinner is flat and light (mean ~252, sd ~0), and the rendered table is mean ~245, sd ~31. Cut on the first table frame - cutting a fraction early shows the boot screen or the spinner.
+
+Cypress starts its own Xvfb for the run (a second display appears in `/tmp/.X11-unix`), so an external `DISPLAY` is ignored; `--force-device-scale-factor` and a CSS `zoom` also do not change the capture.
+
+### Grid columns that are clipped
+
+Handsontable sizes columns to content, so a narrow result can be *wider* than the grid viewport: the horizontal scrollbar appears and the rightmost column (NOTES on `MPE_X_SEARCH`) is cut off. The cell text is still in the DOM, so an assertion passes either way - the column only has to be scrolled into view for the *video* to show why the rows matched.
+
+    const scrollGridTo = (position: 'left' | 'right') => {
+      cy.get('#hotTable .wtHolder').first().then(($holder: any) => {
+        const el = $holder[0]
+        el.scrollLeft = position === 'right' ? el.scrollWidth : 0
+        expect(el.scrollLeft).to.equal(position === 'right' ? el.scrollWidth - el.clientWidth : 0)
+      })
+    }
+
+Setting `scrollLeft` is enough - Handsontable keeps the header clone in step - and the browser clamps it to `scrollWidth - clientWidth`, so that is what scrolling right has to land on. This is a legitimate spec step (it runs in CI), not a recording flag.
+
+### A longer, more readable demo
+
+A spec that doubles as a walkthrough should be a single `it()`: open the table once and make each variation a search in place. The recording then reads as a demo rather than a sequence of page loads, and it is far faster - every extra `it()` pays for the `beforeEach` navigation again.
+
+Two recording-only env flags, both inert in CI because CI passes no env:
+
+    const skipNegative = `${Cypress.env('skipNegative')}` === 'true'
+    const negativeStep = (step: () => void) => {
+      if (!skipNegative) step()
+    }
+    const demoPauseMs = Number(Cypress.env('demoPause')) || 0
+
+    negativeStep(() => {
+      searchFor('trench')
+      assertNoData()
+    })
+
+- `skipNegative=true` drops the steps that legitimately match nothing (wrong case, partial number, value not present), so the recording never shows an empty screen.
+- `demoPause=1500` pauses 1.5s at each row-count assertion, so each result can be read. Apply it in one place (the row-count assertion, which every beat makes exactly once) rather than sprinkling `cy.wait()` through the test - CI still runs the file with no waits at all.
+
+More beats, not a slower take, is what makes a demo longer: a walkthrough of 12 row-count beats takes 52s against 30s for 7.
+
+## Mock services
+
+- One JS file per service under `sas/mocks/sasjs/services/**`, deployed as SASjs stored programs. Shared helpers live in `sas/mocks/sasjs/services/dcMockUtils.js` (`fetchTable`/`parseCsv` for `%webout(FETCH)`, `webOutOpen`/`webOutObj`/`webOutClose` for `%webout`, `mpeFilterMaster`, `mpFilterGenerate`, `mpFilterStore`, `getDdType`, `formatSasValue`, `sasVarsEntry`).
+- Mock data is one JSON file per table at `<drive>/files/<appLoc>/data/<LIBREF>/<table>.json`, written by `services/admin/makedata.js` (which also writes `services/settings.js`). The drive lives under the SASjs Server directory (`sasjs_root/drive`).
+- `makedata.js` self-destructs after a successful run (it deletes itself from the drive so the frontend can detect completion), so re-deploy before re-seeding.
+- **A mock must mirror the real service.** `viewdata.js` once ignored `FILTER_RK` and hard-coded `FILTER_TEXT` to blank, so the viewer's filter silently filtered nothing and its info bar never showed a clause, while the real `viewdata.sas` applies `%mpe_filtermaster` and then `%mp_searchdata`. If a mock is a deliberate stub, say so in a comment and make the divergence explicit - a mock that quietly drops an input turns an E2E spec into a test of nothing.
+
+## Pitfalls
+
+- `sasjs cbd -t server-ci` rebuilds the *mock services* and re-deploys the streamed web app from `client/dist`; it does not rebuild the Angular app.
+- Deleting the drive folder before deploying avoids stale services and stale data.
+- Captured `_webout` JSON, request logs and iteration snapshots belong in `tmp/` (gitignored), never in `sas/mocks/` - see the `dc-sas` skill.
+- The mock server has no auth, so `cy.visit` on `/SASLogon/logout` returns 404 - that is fine, Cypress does not fail on the status code.
+
+## Verification
+
+- `npx cypress run --browser electron --spec <specs>` - all green, and run it more than once when you have just removed a wait.
+- `cd client && npm run lint:check` passes.
+- For a mock change, hit the service directly before writing UI assertions:
+
+      curl -sS -H "Content-Type: application/json" -X POST \
+        --data '{"_program":"/Public/app/dc/services/public/viewdata","SASControlTable":"LIBDS:$41. FILTER_RK:best. SEARCHTYPE:$4 SEARCHVAL:$1000\nDC_JSLIB.MPE_X_SEARCH,0,CHAR,Trench"}' \
+        http://localhost:5000/SASjsApi/stp/execute
+
+  then check `sasparams[0].NOBS`, the row count and `FILTER_TEXT`. Pin those exact numbers in the spec.

 ## Workflow guidelines
 [Wiki Page](https://git.datacontroller.io/dc/dc/wiki/Git-Workflow)
 
+## Git hooks
+
+The repo ships its own git hooks in [`.git-hooks/`](./.git-hooks):
+
+- `pre-commit` - scans staged changes for secrets with gitleaks, blocks commits that would add more than 2MB of new blobs, and runs the prettier check (auto-fixing on failure)
+- `commit-msg` - verifies the commit message follows the [Conventional Commits](https://www.conventionalcommits.org/en/v1.0.0/#summary) standard
+
+The repo `.npmrc` sets `ignore-scripts=true`, so the `prepare` and `postinstall` lifecycle scripts that would normally set `core.hooksPath` during `npm i` never run. After cloning (or if your commits are not being checked), activate the hooks with a one-time command, run from the repo root:
+
+```bash
+git config core.hooksPath ./.git-hooks
+```
+
+The pre-commit hook requires the gitleaks binary provided by the root `@nogoo9/gitleaks` devDependency, so make sure `npm i` has run in the repo root before your first commit.

+  @details Wrapper around mp_validatecol() that adds the Data Controller
+    convention of addressing a format catalog as `LIBREF.CATALOGNAME-FC`
+    to the LIBDS rule.
+
+    The `-FC` suffix is matched exactly and the remainder is validated as
+    a strict LIBREF.DATASET, so the *whole* value is covered by the
+    validation - a bare scan on the dash would leave anything after it
+    unvalidated.  The input column itself is never modified, so a caller
