2. Field writes bypass the client gateway 📘 Rule violation ⌂ Architecture
appendCollectionField directly reads and mutates the collection's Yjs schema in collection-ops.ts instead of exposing that operation through yjs-client.ts. Every new field created from the manager, Board, or Calendar reaches this path, leaving the added validation-dependent write outside the required client access boundary.
Agent Prompt
## Issue description
Collection field creation directly reads and writes Yjs state outside the required client gateway.
## Fix Focus Areas
- src/lib/data/collection-ops.ts[84-90]
- src/lib/client/yjs-client.ts[33-65]
- src/lib/client/collection-editor.ts[89-103]
## Recommended Fix
Expose the field-append read/write operation through `src/lib/client/yjs-client.ts` and update the collection editor to call that gateway while preserving atomic validation and structured errors.

| - **Eligible types: everything except `relation`.** A `relation` value is a list of record IDs with no display string of its own (data-model.md's `PropertyValue`) — every other type (`text`, `number`, `date`, `select`, `checkbox`) already renders as one displayable value via `PropertyValueCell`, so `setPrimaryField` rejects choosing a `relation` field (`ValidationError`), and a retype that turns the current primary field _into_ `relation` clears `primaryFieldKey` in the same transaction rather than leaving it pointing at a now-invalid field. Deleting the current primary field clears it the same way. Both repairs mirror the existing `deleteCollectionProperty`/`updateCollectionProperty` pattern of fixing up stale schema references in one transaction rather than leaving a dangling key for a reader to notice later. | ||
| - **Display value: `primaryFieldDisplayValue(value, property)`** (`src/lib/data/views.ts`) — a plain-text rendering of any eligible type's value (a `select` value resolves through `property.options` to its label; `checkbox` renders "Checked"/"Unchecked"), used for Board's card-title `aria-label`s and other plain-text title fallbacks. Board's card and Calendar's entry normally render their primary field as a full `PropertyValueCell` (so whichever type is chosen — not just `text` — stays directly editable inline); this function is only for places a plain string is needed instead of an editable cell. | ||
| - **Colliding with `groupBy` or `swimlaneBy` (issue #104, #105).** `primaryFieldKey` and Board/Calendar's `groupBy` (§3), or Board's `swimlaneBy`, are independent choices — nothing stops a user from pointing any of them at the same `select`/`date` field. Both Board's card title and Calendar's entry title normally render the primary field as a directly-editable `PropertyValueCell` (§4), which — when `titleProperty.key` matches `groupProperty.key` (Board or Calendar) or Board's `swimlaneProperty.key` — would otherwise sit right next to another editable control for the identical value: Board's matching "Move to column"/"Move to swimlane" `<select>` (§3), or Calendar's own date `PropertyValueCell` rendered lower in the same entry (§4). Both views resolve this identically, by falling back to the same plain non-editable label used when there's no primary field at all (`titleEditableViaCell` in `BoardCollectionView.svelte`, checked against both properties; the same-named derived value in `CalendarCollectionView.svelte`, checked against `groupBy` only, since Calendar has no swimlane dimension): the other control stays the one editable path to that value, and the title cell for every other field keeps behaving exactly as described above. Nothing prevents choosing the same field for more than one of these roles — there's no correctness reason to forbid it — this only changes which control is editable when a choice collides. | ||
| - **Display value: `primaryFieldDisplayValue(value, property)`** (`src/lib/data/views.ts`) — a plain-text rendering of any eligible type's value (a `select` value resolves through `property.options` to its label; `checkbox` renders "Checked"/empty), used for Board/Calendar's card-title `aria-label`s and Calendar's static entry-title text. Board's own card _editor_ still renders the primary field as a full `PropertyValueCell` (so whichever type is chosen — not just `text` — stays directly editable inline); this function is only for the places a plain string is needed instead of an editable cell. |

Update the checkbox display contract in the specification.
primaryFieldDisplayValue and its test both return "Unchecked" for false, and Calendar uses this value for entry titles. Change the specification from “Checked”/empty to “Checked”/“Unchecked”; the formatter and test already match the implementation.

Associate field-label validation errors with their inputs.
FieldManagerDialog.svelte and FieldMenu.svelte display rejected label errors as alerts, but their label inputs do not reference the error text or expose an invalid state. Add stable error IDs and conditionally set aria-invalid and aria-describedby (or aria-errormessage) for label-validation errors while each form is active. Keep unrelated shared errors from marking the label input invalid. The repository requires WCAG 2.1 AA screen-reader support for these forms.

Assert that rejected submissions preserve the schema.
The blank-label tests for collection, blank-board, and blank-calendar submit whitespace and assert only the alert. Add schema assertions after each submission. The existing duplicate-label tests show the expected pattern with getCollection(...).schema. Without these assertions, a handler could report the error and still append a field without failing these tests.

Reject blank labels before generating a unique label.
When generateUniqueLabel is true, insertCollectionField bypasses assertUniqueFieldLabel. A whitespace-only field.label therefore becomes '' and can be persisted in the schema. Reject the empty trimmed label in nextAvailableFieldLabel:
Proposed fix
function nextAvailableFieldLabel(schema: PropertyDefinition[], baseLabel: string): string {
const base = baseLabel.trim();
+ if (!base) throw new ValidationError('Field label cannot be blank');
let candidate = base;📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
