Mapping [1,2,3] to [1,2,3] worked, but reading the editor you could not tell. The rule producing each entry lived behind a chevron as "A list of plain values, not records" plus a hidden row, while every other rule in the mapping is a row in the tree — and the box holding the answer looked empty, because "the entry itself" is stored as an empty path.

What a list holds is now decided by what is put into it. + Value, + Field and + List sit together under a list; using one stops the others being offered, and deleting what was added opens the question again. The checkbox is gone.

The value is an ordinary row. Same source segments, same chevron, same delete — so it takes a transform, a substitution table and a type like anything else. A transform does belong here: the value came from the source, so multiplying each entry of [10,20] by two is meaningful, and there is an end-to-end test that does exactly that.

An empty path reads as the answer it is. The box says the entry itself in the colour of a value rather than the grey of a placeholder, and the assigned count includes it — a correctly built list of values used to sit in the "not assigned yet" tally for ever with nothing for anyone to fill in.

Entries written into a list by hand get the full row too, chevron and type badge included.

One behaviour change: a list that already has fields no longer offers + Value. Converting records to values means removing the fields first — offering the switch would mean silently deciding what happens to the rules already there.

Tests: TS unit 273 → 280, and 68 mapper end-to-end tests passing. Two new e2e — the scaffolded [1,2,3] case that prompted this, and the type-and-transform one. Three existing tests moved off the checkbox onto the buttons.

What a list holds is decided by what is put into it: + Value, + Field and
+ List sit together, and using one stops the others being offered. The value
each walked entry produces is an ordinary row — source, transform, table,
type, delete — instead of a setting behind a chevron with a hidden row under it.

An empty path there means the entry itself, which is the usual answer and what
the scaffolder writes, so the box now reads as that rather than as a blank and
the assigned count includes it. An entry written into a list by hand gets the
same full row as a field.

📝 Summary

Summary

  • Replaces the plain-value list checkbox with + Value, + Field, and + List actions.
  • Renders plain-value list items as editable tree rows with source paths, transforms, substitutions, types, chevrons, and deletion.
  • Treats an empty item path as the entry itself and counts it as assigned.
  • Prevents conflicting list content types until existing content is removed.
  • Adds reducer, output-tree, assignment, and filtering support for list items.
  • Updates end-to-end helpers and adds coverage for plain-value lists and transformed values.

Risk: risk:medium. The change affects reducer state transitions, undo behavior, list rendering, assignment counts, and mapper editing flows.

Security-sensitive areas: None identified. The change does not modify authentication, authorization, secrets, or network access.

Test coverage impact:

  • TypeScript unit tests increase from 273 to 280.
  • 68 mapper end-to-end tests pass.
  • Adds coverage for list item creation, removal, assignment, filtering, empty paths, and transforms.

Operational concerns:

  • No migration or deployment procedure is required.
  • Existing mapper state must follow the updated list item model.
  • Rollback should include the UI, reducer, output-tree, and test-helper changes together to avoid model and rendering mismatches.

Walkthrough

The mapper now creates plain-value lists through an add-value action. List items appear as editable output rows with item-specific assignment handling. Reducer, output-tree, component, and end-to-end tests cover the new workflow.

Document-scoped empty paths can be presented as entry-scoped mappings and produce unexpected list output. The fixed-entry display and affected test walkers should also be corrected before merge.

pass emptyPathLabel="the entry itself", so empty paths display the entry’s
meaning instead of the generic order.customer placeholder.

In `@SW.Bitween.Web/ClientApp/src/components/nativeMapper/ValueCell.tsx`:
- Line 83: Update the meansWholeEntry logic in ValueCell to require source.kind
=== "path" in addition to emptyPathLabel being defined and path being empty;
preserve the existing label behavior for entry-relative paths while treating
document-root paths as ordinary mappings.

In `@SW.Bitween.Web/ClientApp/src/lib/nativeMapper/outputTree.ts`:
- Line 96: Update the test walkers that implement keysOf and shown to recognize
OutputItemNode item nodes as leaves instead of reading children or recursing
with undefined. Ensure keysOf includes the item node’s errorKey, while shown
returns the appropriate leaf result and preserves existing handling for non-item
nodes.

Comment thread SW.Bitween.Web/ClientApp/src/lib/nativeMapper/outputTree.ts
"The entry itself" is only true of a path read from the entry — switch the
box to the document and an empty path is the whole document written into
every slot, so neither the label nor the assigned count claims it now. An
entry written into a list by hand reads the list's scope rather than an entry
of it, so it loses the mark too.

Adds tsconfig.test.json, wired into the build: nothing typechecked the tests
or the e2e specs, which is how a walker came to call itself with undefined for
a node that has no children. It found a second one of those straight away.
