Old `index.html#board`, `#coefficient`, `#inventory` and `#contribute` bookmarks route here; without JavaScript the home still offers the workspace link.

+## Latest public work is a reading cut
+
+`research.html#latest-work` is static editorial navigation checked at its displayed
+UTC time. It links the landed soft-model chain at Math `07320089`, the separately
+landed cap formalization at `0fda855b`, exact public C81–C84 issue-comment proofs and
+reviews (model and source-bound actual/contact scopes kept distinct), the finite numerical work at main `1e1c9a1c`, and the existing catalog and
+query sources. The named boundaries are part of each reading path. This is a
+curated selection plus full upstream navigation, not a complete artifact catalog,
+scientific-status register or automatic synchronization service.
+
+Exact-commit citations preserve the reading cut. The **Check newer work** section
+intentionally follows mutable upstream branches and discussions. Comment links
+identify the public record but comments remain editable; their reviews record the
+reviewed identity. A missing source is unavailable evidence. No browser fetch or
+execution of those sources is claimed. The Library, status and museum snapshots
+retain all their original pins and are not refreshed by this section.
+
+The existing four light/dark desktop/mobile source-card browser cases now also
+exercise the Home → Latest public work route, native keyboard fragment focus,
+repeated source-identity disclosure, Back/Forward navigation, no document overflow
+and the static route with remote source requests refused. Each case retains a
+latest-entry screenshot. Actual source identity readback is a separate engineering
+check, not something established by a screenshot or link.
