fix(mocks): catalogs are not datasets, and getcolvals validates shape before resolution

Reviews 893 and 894 on #518.

894-1 and 894-2 - a -FC request named a format catalog, and the mock answered
it with the sibling dataset. Stripping the suffix for validation made the name
canonical but also changed which object was resolved, so LIBREF.NAME-FC returned
NAME's rows for a name that is not a catalog at all. Now the MPE_TABLES
registration decides: if it carries a row for NAME-FC the member is a catalog
and is streamed as LIBREF.NAME.ext; if it does not, the request is not a catalog
and the estate's own answer is reproduced - syscc=1012 from %mp_cntlout,
recorded as public/getrawdata/catalog_suffix_on_dataset. The catalog the fixture
does hold, MPE_X_CATALOG, has no format entries, so its listing is empty; that
is recorded in the parity README beside the other fixture divergences rather
than left as an unexplained empty body. The test that pinned the object swap now
asserts both halves.

894-3 - getcolvals answered a well-formed libref it does not have with "Invalid
libds", and a malformed one with "Target table not found": the two rules were
the wrong way round. getcolvals.sas validates the SHAPE first with
%mpe_validatecol(...,LIBDS,...) and that is the only "Invalid libds"; the table
is then left to %mp_derivedvars, which aborts "Target table not found: <LIBDS>"
with its own MAC. Both are now recorded: public/getcolvals/wrong_libref uses a
valid-length NOLIB and pins the resolution abort, and the new
public/getcolvals/malformed_libds pins the shape abort with an 11-character
libref. fault-paths.test.js went with them.

893-2 - loadTableFrom duplicated loadTableData, so the two could drift: one
loadTableFile(libref, tableName) now serves both, with the control library as
the default.

893-3 - an unreadable or malformed table file was swallowed into null and
surfaced as "Target table not found". It now throws naming the file, because a
broken fixture should not send the next reader looking for a missing table; an
absent member still returns null and keeps the recorded abort.

Tests: 149 pass. Each of the three behaviour changes was run against the
previous code first and fails there - swallowing parse errors, answering the
catalog with the dataset, and restoring the inverted getcolvals rule.
parity/check.js ok on all 25 scenarios.

 ### 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.

+# 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
+
+`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.
+- `MPE_X_CATALOG` holds no format entries, and `viewtables` identifies a catalog by the absence of variables, so a `-FC` download of it is an empty listing where the estate's `%mp_cntlout` would produce the FMTNAME/START/END/LABEL/TYPE columns with no rows. The service path around it is pinned instead: `public/getrawdata/catalog_suffix_on_dataset` records what the estate answers when the suffix names something that is not a catalog, and the mock answers that case the same way.
+
+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.
