What

Closes #113. A published entry whose collection's expiry has passed now shows Ended (collection rule) beside its status, in the collection list and in the entry editor header (RFC-0042 §3.3). Before this, such an entry looked plainly published while the site had already left it out of lists, or answered "not found".

• endedByRule (apps/studio/src/components/listings/ended-rule.ts) uses the same derivedGate / entryVisibility as the site, so Studio and the site agree. The end is exclusive.
• The entry's own state comes first. Drafts, embargoed entries and entries whose own "Hide after" has passed get no badge.
• A translation reads its original's date only while the original is published, as the site does.
• The badge is a new @cloudhal/ui block, ToggletipBadge: a secondary badge with a 14 px CalendarX icon inside a button.
  • It opens on hover, on keyboard focus and on a press, so a tap opens it on touch screens.
  • The reason is also part of its accessible name.
  • It names the date field, the instant in the site's time zone (grace included; for a date field, the next midnight) and what the site does (unlist or hide).
• The badge and its listings words load only for collections that have an expiry (lazy chunk).
• DESIGN.md §2ah and the component table document it.

Verification (local)

• Studio Vitest: 80 files, 1297 tests pass. ended-collection-rule.test.tsx adds 18: unlist/hide, draft, embargo, own "Hide after", exclusive end, grace, translation with a published or draft original, list and editor, toggletip by keyboard and press.
• @cloudhal/ui block tests pass.
• These also pass: pnpm design:lint, the typechecks, pnpm size:check, pnpm drift and the Studio build (bundle 391.0 kB of 420 kB).
• Screenshots on a local site with an events collection (expiry unlist on endsOn) at 1440 and 390 px, plus pseudo-RTL:
  • The entry that has ended shows "Published" + "Ended (collection rule)"; the upcoming one shows only "Published".
  • The editor header shows the badge.
  • The toggletip opens with the right text.

Review needed

• Turkish wording: listings.ended.badge is "Sona erdi (koleksiyon kuralı)", and the reason text uses "… zamanında". Turkish is marked reviewed, so please check this wording. The other languages are AI drafts awaiting review, as usual.

Checklist

• pnpm check and cargo test --workspace pass locally. The Studio and UI suites, design lint, typecheck, size check and drift were run piece by piece; there are no Rust changes. CI runs the full set.
• Contract change? No contract change; the i18n params.ts was regenerated with pnpm gen and committed.
• User-visible change in a published package? .changeset/studio-ended-collection-rule.md (@cloudhal/cli patch, Studio ships in the CLI)
• Commits are signed off (git commit -s, DCO)
• Docs / AGENTS.md updated if behaviour or commands changed (DESIGN.md §2ah)
