Summary

• Add persistent MiniApp shortcuts below Task Board, with add/remove actions in installed-app menus and details. Preferences are isolated by the selected device, and shortcuts use the existing launch and native-window transfer flow.
• Open a compact context-composition overview from the composer, including category previews and an explicit action to open the detailed report. Inline reads work during a turn and discard stale device responses.
• Present context usage against the reported capacity, including unused space and explicit missing/overflow states. Refresh report titles while retaining compatibility with saved panels.
• Keep lower-pane tabs visible in split canvas layouts and shorten the session-history menu reveal using an opaque surface.
• Update en-US, zh-CN and zh-TW strings, user guidance, and focused verification instructions.

Type and Areas

Type: Feature, UI/UX, regression fix, tests and docs.

Areas: Shared Web UI, MiniApps navigation, FlowChat context usage, content canvas and session-history menu.

Motivation / Impact

Installed MiniApps can be opened directly from the left navigation. Context usage can be inspected without opening a report tab, while detailed reports show consumption relative to model capacity. Split canvas layouts retain tab actions for lower groups.

Verification

Passed:

• pnpm run check:web (Web UI type-check, canvas SDK, Appearance, theme color and visual contracts).
• pnpm run i18n:audit (zero warnings).
• pnpm --dir src/web-ui run icons:check.
• pnpm run motion:audit completed as an informational inventory; the changed history menu retains its reduced-motion path.
• git diff --cached --check before commit and git diff origin/main...HEAD --check after commit.
• node scripts/check-git-object-sizes.mjs --base origin/main --head HEAD.
• Focused command below: 28 test files, 420 tests passed.

Remote coverage: local DOM/store fixtures exercise simulated SSH data and workspace restrictions, Peer device switching and stale-response ownership, and the dispatch report source. No live Remote Workspace, Remote Control, Peer Device or Detached Dispatch scenario was exercised. Native rendering, browser/desktop interaction checks and screenshots remain pending per the repository instructions.

Reviewer Notes

AI-assisted. Testing level: lightly tested with focused automated checks; no manual or end-to-end validation.

Based on refreshed origin/main at b15a075a1. The existing context-report implementation from #3614 remains the baseline. Checked all 29 open PRs, including drafts, and inspected overlapping diffs in #3588, #3484, #3580 and #3390; those changes concern compaction, skill availability and loop-detection copy rather than these navigation/overview changes.

New navigation preferences tolerate older empty payloads and unknown fields. Legacy usage-report payload round trips and missing context-capacity behavior are covered by tests. No Rust command, transport contract or dependency changes.
