Keep the original iOS notification row design. The latest event is the parent, with a compact disclosure accessory; older events expand as separate indented native List rows. Children remove inherited workspace/Mac labels but retain distinct titles, content, timestamps, unread state, and individual actions.

Expansion lives in the feed projection, so row identity and the original open/read/context-menu action path are preserved. Expansion uses the system smooth animation and respects Reduce Motion. Existing adjacent same-computer/workspace/surface grouping and its two-hour boundary are unchanged.

HIG reference: Lists and tables.

Verification: device and simulator compilation passed; corrected ngroup installed and authenticated on Aziz, with a usable same-account connection and three demo workspaces. A real iPhone screenshot confirms the expanded native rows and removed duplicate metadata. Focused projection and interaction tests are rerunning after updating to current main. Full package-conventions lint still reports pre-existing repository violations; no newly introduced violation is being suppressed. Final integrated rebuild is in progress.

Summary by cubic

Groups adjacent iOS notifications from the same workspace and computer into a single row showing the newest update first, with an expandable control revealing older, indented history. Previously every notification rendered as its own row.

  • Nested rows skip repeating headline, source, and computer labels while keeping each notification's title, content, timestamp, unread state, and individual actions.
  • The disclosure control shows the update count, has VoiceOver labels and localized show/hide text, and skips expansion animation when Reduce Motion is on.
  • Group identity stays anchored to a stable event, so expanded groups keep their toggle state as new notifications arrive, when loading more history, or when source retention prunes the anchor.
  • UI tests verify history renders as separate, independently actionable rows, including the mark-as-read swipe; indentation affects only visual layout, not hit targets.

Written for commit 963b2f5. Summary will update on new commits.

Summary by CodeRabbit

  • New Features

    • Notification history is grouped by related activity, with earlier notifications available in expandable sections.
    • Expanded history appears as indented nested rows with streamlined repeated details.
    • Group controls show update counts and let you show or hide earlier notifications.
    • Expanded groups remain open as new notifications arrive.
    • Related activity is separated by workspace, computer, and surface.
  • Accessibility

    • Added VoiceOver-friendly labels and localized text for notification history controls.

📝 Walkthrough

Walkthrough

The notification feed groups related notifications within a two-hour window, displays older items as nested rows, and preserves expanded groups during projection updates. Preview data, localization, and tests cover grouping, expansion, inherited metadata, read actions, and collapse behavior.

Changes

Notification feed history

Layer / File(s) Summary
Activity grouping and nested row metadata
Packages/iOS/CmuxMobileShellUI/Sources/CmuxMobileShellUI/NotificationFeedListRow.swift, Packages/iOS/CmuxMobileShellUI/Sources/CmuxMobileShellUI/NotificationFeedRowPresentation.swift
Notification models form stable, time-bounded groups. Nested rows receive inherited display context.
Projection expansion state
Packages/iOS/CmuxMobileShellUI/Sources/CmuxMobileShellUI/NotificationFeedProjection.swift
Sections derive grouped rows. Projection state toggles groups and preserves group identity and expansion during rebuilds.
Disclosure and nested row rendering
Packages/iOS/CmuxMobileShellUI/Sources/CmuxMobileShellUI/NotificationFeedRow.swift, Packages/iOS/CmuxMobileShellUI/Sources/CmuxMobileShellUI/NotificationFeedView.swift, ios/cmux/Resources/Localizable.xcstrings
Rows render disclosure controls, nested indentation, inherited labels, timestamps, provenance, accessibility text, localization, and reduced-motion behavior.
Preview fixtures and validation
Packages/iOS/CmuxMobileShellUI/Sources/CmuxMobileShellUI/NotificationFeedPreviewView.swift, Packages/iOS/CmuxMobileSupport/Sources/CmuxMobileSupport/Debug/UITestConfig+NotificationFeedPreview.swift, Packages/iOS/CmuxMobileShellUI/Tests/CmuxMobileShellUITests/NotificationFeedHistoryTests.swift, ios/cmuxUITests/cmuxUITests.swift, Packages/iOS/CmuxMobileTerminal/Tests/CmuxMobileTerminalTests/AccessoryEdgeFadeTests.swift, ios/cmuxPackage/Tests/cmuxFeatureTests/cmuxFeatureTests.swift, ios/cmuxPackage/Tests/cmuxFeatureTests/MobileIrxControlLaneClaimsTests.swift
Debug preview mode adds related history items. Tests validate grouping, expansion, child read actions, collapse behavior, and related test compilation updates.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟡 Moderate · up to a3841

This change groups notification history and allows older entries to expand as nested rows. Expanded groups may unexpectedly collapse during history trimming, and malformed empty groups may crash when rendered; resolve these issues before merging.

Verification: all 8 NotificationFeedHistoryTests passed and Xcode reported TEST SUCCEEDED, including newer arrivals, row-window extension, and source-retention pruning (https://github.com/manaflow-ai/cmux/actions/runs/33944137197/job/101247214618). That job is red because the workflow postprocessor incorrectly counted the Swift Testing suite as zero tests after the successful run. The merged-head native-row UI test passed with 1 selected test and 0 failures, exercising expand, child mark-read, parent state, and collapse (https://github.com/manaflow-ai/cmux/actions/runs/33944704454/job/101248784731). Both added regression baselines fail as expected: pagination (https://github.com/manaflow-ai/cmux/actions/runs/33942992077/job/101244029357) and source retention (https://github.com/manaflow-ai/cmux/actions/runs/33944115073/job/101247137611). Required checks passed on merge head 963b2f5. Full manual iOS workflow status also includes existing package-conventions lint failures outside this change. The final ngroup notification code is installed on Aziz, signed in with the personal profile, trusted-paired to the same-tag Mac, and verified through a usable RPC session with four workspaces. Approved layout was visually checked on the phone; automated indentation pixel coverage remains a documented follow-up.
