Step 5 of RFC-0042's rollout (ADR-0044), built on #103–#106.

Collection settings: three cards (lazy, each saving only its own setting)

• Listing fields: up to 4, ordered. A list_field_in_use error links to the pages that use the field.
• Expiry: date and datetime fields only; unlist or hide, explained in words; grace minutes. A live count shows how many published entries are already past it. gates_unsupported explains that the site must be deployed first.
• Structured data: a type picker, and one row per path (required first). Each row offers only sources that fit the path; enum constants come from the vocabulary. checkPreset issues show while editing, and a refused save puts its issues on the right rows. A JSON-LD preview for a chosen entry links to the Rich Results Test.
• Read-only without site:settings.

API: GET /api/sites/:siteId/entries/:entryId/structured-data (content:read; allowed in the playground), mirroring MCP's preview_structured_data.

Collection list

• Listing-field columns, formatted with formatFieldValue.
• Filters (date presets upcoming / past / set / empty) and sort buttons on number and date columns.
• State lives in the URL. While a filter or sort is set, the list is server-paged through GET /entries.

Listing pages and the page editor

• "Create listing page" makes a draft page at the collection prefix with a contentList; with a date list field and an expiry, it defaults to "upcoming, soonest first".
• The page editor's content list gets condition rows (only the operators each field type allows) and an order. invalid_query issues show on their row.

Labels and errors: tools.preview_structured_data, wording for the five new error codes, and the expires auto-check reason. ErrorBanner shows a 409's own wording when its code has one.

i18n: a new lazy namespace, listings. Drafts for the other 18 languages, unreviewed.

Checks

• Studio: 1274/1274, including 17 new tests.
• ui: 210/210.
• api: 421/421.
• turbo typecheck: 20/20. Design lint (396 files), size check and Biome pass.
• Initial load: 390.0 kB gzip, +0.8 kB (budget 420). About 0.2 kB is core strings, 0.3 kB the router's URL check, and the rest a Kumo chunk split.
• Screenshots at 1440 and 390 px.

Trade-offs and follow-ups

• Paging is previous/next while a filter or sort is set.
• A translation's shared fields can show empty in list columns.
• The page-editor preview ignores where; this is the known gap in renderSectionHtml from feat(renderer): collections stage 3 in the renderer (RFC-0042 step 3) #105.
• The "Ended (collection rule)" entry status from RFC §3.3 is not done.
• apps/studio/src/i18n/generated/ is excluded from the size check, like the other generated folders.

Changeset: minor (cli, api).
