 Complete the Android/client contract pivot before implementing backend behavior. The next release path targets a remote upstream Hermes Agent gateway/API server directly; `apps/companion` is legacy compatibility only.
 
-- [ ] **R1 — Adaptive/accessibility quality pass**
+- [ ] **R1 — Execute and document the adaptive/accessibility device matrix**
   - Small phone, normal phone, tablet/two-pane behavior; portrait/landscape.
   - Font scaling, TalkBack semantics, contrast, touch targets, reduced motion, IME behavior.
   - Verification: emulator/device matrix evidence documented in `docs/ROADMAP.md`.
+  - Source-level progress on 2026-07-24: removed the portrait lock, enabled resize-on-IME, added deterministic phone/landscape/tablet layout policy and tablet two-pane chat, stacked dense controls for narrow/large-font layouts, respected the disabled system animator-duration setting for top-level navigation, added headings/live regions/roles/state descriptions, raised interactive targets to at least 48dp, and bounded very large message/code rendering while retaining full-copy actions for code and tool output.
+  - Source verification on 2026-07-24: the required recovery preflight passed immediately before this run; direct JUnit execution of the cached, source-current Android unit classes passed all 61 tests, including all 4 `AdaptiveQualityTest` cases; and `git diff --check` passed. A direct writable-cache Gradle retry was blocked before project execution by `java.net.SocketException: Operation not permitted`. ADB is installed, but its daemon sockets are sandbox-prohibited; no emulator executable, AVD, `/dev/kvm`, USB device bus, or running target is available. R1 remains unchecked because no emulator/device matrix evidence exists.
