test(cypress): one openTableFromTree command instead of thirteen copies

Thirteen specs carried the same local helper: find the library node whose text contains a fragment, expand it, then click the table whose name contains another, by iterating a jQuery collection captured a moment earlier and calling .click() on the node that matches. That captured reference is the reason the suite is fragile under a route that fetches its chunk: expanding a library replaces its subtree once the child tables load, and a route that is still fetching re-renders the tree again, so the node clicked is a node the DOM no longer holds. The command re-queries at each step - filter the tree nodes by text, then filter the table links the same way - and ends by waiting for the header's per-column dropdown, which is what proves Handsontable has populated the header rather than just the row shells. Specs call cy.openTableFromTree(library, table); the two specs that need a callback of their own (licensing, liveness) and viewbox's variant keep their local helpers for now. Not verified locally: the Cypress renderer crashed under the load this machine is carrying, so CI is the first run of this.
test(cypress): click the table node the parent label covers

 # 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.
+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` 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).

+  # 4.14.0 is the pin because it is the first release that compresses its
+  # responses and sends cache headers for the app it streams (sasjs/server#575).
+  # That is not cosmetic here: the audit runs against this server, and the app it
+  # serves is a single 4.83MB build output. Measured on the previous pin, same
+  # build and same machine: FCP 8.48s and 0.34 performance with the assets served
+  # raw, 2.81s and 0.49 with the same bytes gzipped and hashed files immutable.

+  # 4.0.0's breaking change is the auth statuses - `POST /SASjsApi/auth/token` and
+  # `/auth/refresh` answer 401 where they answered 403, the undocumented DELETE on
+  # the logout route is gone, and `GET /SASLogon/logout` answers 500 where it
+  # answered 403 when the session store fails. The estate does touch all three,
+  # through @sasjs/adapter: auth/AuthManager.js logs out with a GET on the logout
+  # route and auth/getAccessTokenForSasjs.js posts the token. What it keys on is
+  # the call succeeding rather than the code being 403 in particular, so 403 to
+  # 401 changes nothing here - and the suite on this pin checks the logout path

  # 3.12.0 is the floor: /ddc-host carries `timing=early` from there, which
  # client/cypress/e2e/va-ddc-host.cy.ts needs. 3.12.2 also carries the
  # packaged-executable fix for the same page, so the version the tests run
  # against is the one that ships.

+# SAS parity harness
+
+Records what a deployed SAS backend answers, then replays it against the JS mock estate and reports the differences. The mock services are a second implementation; this is the only check that compares behaviour rather than source.
+
+## The privacy rule
+
+**A golden is a projection, never a copy.** `project.js` keeps a fixed set of members per scenario, drops the whole envelope (`SYSHOSTNAME`, `SYSSITE`, `SYSUSERID`, `AUTOEXEC`, `MF_GETUSER`, job and process ids, timings, `_PROGRAM`), replaces the identifiers the comparison needs (`DC######` and `DC_JSLIB` to `<LIBREF>`, absolute paths, URLs, emails, staging ids, ISO timestamps, secrets by key name), and then refuses to publish if:
+
+- any identifier class survives (FQDN, IPv4, absolute path, libref, email, eight-digit DC id), or
+- any literal the envelope just discarded still appears anywhere in the projection.
+
+That second check is what catches a hostname echoed inside an error message or a home path inside a `DCPATH` value, which no regex would find. `record.js` runs both before writing; `parity-golden.test.js` runs the same scan over every committed golden, so a hand-edited file cannot slip through. One envelope member is dropped but not denied - `_PROGRAM`, the service path of the request that was just made. It is not uniform across deployments (it carries the target's appLoc), but it is in the URL of the request itself, so publishing it adds nothing a reader does not already have. An abort answers it as `MAC`, so the value lands in the golden as it arrived; the diff comparing it is a consequence of that, not a reason to keep it.
+
+**Record only from the organisation's synthetic estate** - one seeded by `makedata`, plus `createdemodata` when a scenario needs the fixtures. A customer site would put their rows into a file that looks anonymous and is not: row values are data, not identifiers, and no scan can tell a customer's rows from a demo's. The recorder records `estate: synthetic` in `_meta` as a claim a reviewer can check.
+
+## Use
+
+```
+# record every scenario from the server target (needs sas/.env.server)
+node sas/mocks/test/parity/record.js --target server
+# a private estate with its own certificate
+node sas/mocks/test/parity/record.js --target server --ca /path/to/estate.pem
+# throwaway host only - warns, and _meta records tls: unverified
+node sas/mocks/test/parity/record.js --target server --insecure
+
+# record one (an id on its own matches every service that uses it)
+node sas/mocks/test/parity/record.js --target server --scenario default
+node sas/mocks/test/parity/record.js --target server \
+  --scenario editors/getdata/mpe_tables --libref DC634301
+
+# replay against a mock estate and diff (no server, no credentials)
+node sas/mocks/test/parity/check.js
+node sas/mocks/test/parity/check.js --advisory      # report, exit 0
+```
+
+TLS is verified by default: the response becomes the reference the mock is measured against, and the tool runs with estate credentials. A target that is not `https://` is refused outright - the request carries a bearer token and would send it in the clear. `--insecure` is opt-in, says so on stderr, and is recorded in `_meta.tls`, so a golden recorded over unverified transport can never be mistaken for one that was not.
+
+Raw responses land in `.captures/` (gitignored) so a refusal can be diagnosed without hitting the estate again. Only the projection is committed, under `golden/<service>/<scenario>.json`.

+`scenarios.json` names, per scenario: the service, the URL parameters, the members to keep, and why the scenario exists. Everything not named in `members` is dropped by the projection, so a member added upstream is excluded until someone names it - the default is to publish less.
+
+A service that reads a **table input** rather than URL parameters takes an `input` block:
+
+```json
+"input":     { "table": "SASControlTable", "rows": [ { "LIBDS": "{{LIBREF}}.MPE_TABLES", "FILTER_RK": -1 } ] },
+"mockInput": { "table": "SASControlTable", "rows": [ { "LIBDS": "DC_JSLIB.MPE_TABLES",   "FILTER_RK": -1 } ] }
+```
+
+`input` is posted to the estate and `mockInput` is handed to the mock at replay, because the rows name the control library and the two sides do not share one - only the values differ, and the shape is the point of the comparison. `{{LIBREF}}` is filled from `--libref`, so the estate's library name stays out of the repository.
+
+The uploaded file is not a plain CSV: the server reads its first line as the SAS `input` statement and the rows from line two, so `record.js` writes informats (`LIBDS :$32. FILTER_RK :best32.`) and the runtime rewrites `:$N.` to `:$char`. Get that wrong and the control table arrives with zero observations, which the service reports as `syscc=1012 prior to dc_getsettings` rather than as a bad upload.
+
+A scenario recorded before the mock has been aligned carries `"gated": false`. The gate then prints its difference count and does not fail, and `check.js` labels it `ADVISORY`. The flag is a to-do with a number attached - remove it when the mock matches, at which point the scenario is enforced like the others.
+
+## Refreshing the goldens
+
+The build pipeline cannot reach a SAS estate, so re-recording is an **ad-hoc job run by an agent or a maintainer** holding the estate credentials - not a scheduled CI job. That splits the harness in two:
+
+- **The gate is offline and stays in CI.** `parity-golden.test.js` scans the committed goldens, and `parity-check.test.js` replays every scenario through `parity/replay.js` against a mock estate built by the test harness - no server, no credentials. Both run in `node --test sas/mocks/test/*.test.js`, so a mock change that alters a payload fails the pull request. A scenario with no golden fails rather than skipping.
+- **Differences are declared, not ignored.** A scenario's `accepted` list in `scenarios.json` names the JSON path of each difference that is expected (the estate's own admin group, its timezone, SAS's space padding of a blank character value) with the reason. Anything else fails, and so does an accepted entry that has stopped differing - the list shrinks to the real residue instead of hiding a fix.
+- **The refresh needs the estate.** Where `sas/.env.server` exists: `record.js --target server`, then `check.js`, then the suite; commit the changed projections. A non-empty diff names the member that moved, so the refresh is a reviewed change rather than a silent overwrite - and when only SAS moved (a version bump, an upstream service change), the diff in the pull request is the whole report.
+
+### Runbook
+
+Run from the repository root, with the estate reachable and `sas/.env.server` holding an `ACCESS_TOKEN` (what `sasjs auth login -t server` writes). Deploy the release you are recording from first: a golden describes the build it was taken from, and recording against the previous one silently pins the old behaviour.
+
+1. Find the control library. It is the estate's own `DC######`, not the mock's `DC_JSLIB`. `node sas/mocks/test/parity/record.js --target server --scenario public/startupservice/default` answers it, but the committed golden masks it (`DCLIB` projects to `<LIBREF>`), so read the value from that scenario's raw response, `.captures/public/startupservice/default.raw.json` - `globvars[0].DCLIB`. That run also refreshes the startup golden.
+2. `node sas/mocks/test/parity/record.js --target server --libref DC######` re-records every scenario; add `--scenario <service>/<id>` to scope it.
+3. `node sas/mocks/test/parity/check.js` replays the new goldens against the mock estate and prints each difference. A `DIFF` line means the mock must change; an `ADVISORY` line means a scenario still carries `"gated": false`.
+4. `node --test sas/mocks/test/*.test.js` runs the gate the pull request will run. A scenario whose `members` changed fails on the recorded list, not on a value - re-record it rather than editing the golden.
+5. Commit the projections, and in the same commit delete any `accepted` entry that has stopped differing and add one for a difference that is genuinely estate state, with a reason a reviewer can weigh.
+
+Two refusals are worth recognising. `REFUSED to publish` names a literal the projection kept - the raw response is in `.captures/<service>/<id>.raw.json`, gitignored, so the refusal can be diagnosed without hitting the estate again; fix the projection or the service, never the golden. A missing `sas/.env.server` means no credentials on this machine: the refresh is an agent or maintainer job, never a CI one, and the target must stay inside `SYNTHETIC_TARGETS`.
+
+## The case a column name is reported in
+
+A table keeps the case SAS created it with - `proc sql create table` with `alert_event` leaves `alert_event` in `dictionary.columns`, and the DDL reports it that way - while every payload the client reads (`getdata`, `getcols`, `viewdata`, the variables in `$sasdata`/`$viewdata`) reports the name upper case. So the mock's table files store the creation case, which is what the DDL generator prints, and every service builds its payload keys through `payloadKey()` in `dcMockUtils.js`. A service that reads a row by `col.name` instead of `payloadKey(col)` gets `undefined`, which shows up as an empty grid rather than as an error.
+
+## Fixture divergences that are deliberate
+
+`createdemodata` owns two differences from a SAS estate, both driven by existing specs rather than by the product:
+
+- MPE_X_TEST loses one of the rules `mpe_makedata.sas` seeds for it: the `HARDREGEX` on SOME_SHORTNUM, which rejects 1-5. `regular_excel.xlsx` - the file the specs upload to `dc_jslib` - holds five rows where SOME_SHORTNUM is 5, so with the rule in place that upload is refused before it reaches the approval screen. SAS's other rules for the table are kept, because they are the ones the mock has always had and `editor.cy.ts` exercises them (the dropdown on a cell comes from the `HARDSELECT_HOOK` on SOME_NUM).
+- MPE_X_TEST's SOME_CHAR/SOME_DATE/SOME_DATETIME/SOME_TIME carry LABELs that differ from their names, which `viewer-labels.cy.ts` asserts, while a SAS estate has no labels on that table.
+
+Both are asserted in `test/createdemodata.test.js`, so a change to either side is a failing test rather than a broken Cypress run. A future scenario covering `editors/getdata` on MPE_X_TEST would show them as accepted differences; today the startup scenario does not touch that table.
+
+Recording is always against the synthetic estate, and that is enforced rather than asserted: `record.js` carries the list of target names that point at it (`SYNTHETIC_TARGETS`, currently `server`) and refuses every other target, including the ones that point at a customer site. It cannot be detected from the response - `makedata` is the installer, so a customer's control library holds the same rows. An agent refreshing goldens against a customer site would put their rows into a file that looks anonymous and is not, and no scan can tell the two apart afterwards.
+
+## Status
+
+Every scenario in `scenarios.json` is gated: `parity-check.test.js` replays it against the mock estate and fails on any difference that is not declared in `accepted` with a reason. A scenario recorded before the mock has been aligned carries `"gated": false` instead, which makes it advisory - the gate prints its difference count and does not fail - and the flag comes off once the mock matches. The scenario's own `note` says what it pins; the per-scenario diff counts live in the gate's output, not here, because a count changes with any mock edit.
+
+## What cannot be goldened
+
+Some answers are estate state rather than service behaviour, and a golden for them would be a recording of one installation's setup. They are excluded instead of accepted difference by difference, because the difference is in the rows, not in a path:
+
+- `public/getgroups` lists the SASjs Server's own groups (`all-users`, `public`, and every group created on that server). A fresh install and a test estate answer different lists, so the mock derives its groups from `MPE_GROUPS` and the startup scenario accepts the admin group's name as estate state.
+
+Next, and why the obvious recording does not work:
+
+- **A table the caller may not see.** `%mpe_accesscheck` lets an admin through, and the synthetic estate's user is in `DC_ADMIN_GROUP`, so every table is editable there and the "not authorised to edit" abort cannot be produced without changing the estate's security rows - which would make the golden a recording of that change. It needs an estate with a non-admin login before it can be recorded.
+- **The older dialects of `public/getddl` that the client does not offer.** All three flavours the download menu names - SAS, TSQL and PGSQL - are generated from the table's own metadata, and each is recorded for `MPE_TABLES`, which is the table that pins them. A fourth flavour, or a change to one of these, needs its own recording before it is generated.
+
+See the parity section of the `data-controller` skill for the surrounding workflow.
+
+## Provenance of a golden
+
+Every golden is written by `record.js` from a **live response**, never from the mock - a file that the mock produced would make the comparison circular, so the recorder makes the source legible in `_meta`:
+
+- `sas` is read from the response envelope's `SYSVLONG` (family only, e.g. `9.4M9`). Only a SAS runtime emits that, so a golden carrying it cannot have come from the mock. When a scenario answers with something other than a SAS JSON envelope - `public/getrawdata` returns the CSV text itself - the recorder writes `unknown`, which is the accurate answer rather than a guess. The accepted differences for such a scenario are still read from a live estate response.
+- `estate` is `synthetic` because the target in `sasjsconfig.json` declares it, and `record.js` refuses a target that does not: the flag is the recorder's evidence, not a label typed into the golden.
+- `tls` records whether the conversation was verified or the opt-in `--insecure` was used, so a reader knows how the answer was obtained.
+- `dc` is the version in `package.json` at record time. The estate does not report its own DC version through any service, so this is the repository's version and not the deployment's - the one field of `_meta` that is not read from the response, and it is named here so nobody reads it as the estate's.
+
+A golden that is stale - recorded against an older `dc` or a different `sas` family - still compares, because the body is what the gate reads; the `_meta` block is where a human sees that the answer predates their change.
