TUI Epic 5: cut Activity + Graveyard fixes

[TraderSamwise]

Final epic of the TUI IA redesign — two small cleanups that complete the north-star screen set.

What changed

Phase 1 — Cut the Activity screen. Activity was a filtered "needs attention" list, but the dashboard already surfaces attention via its status pills/colors and the [u] next-attention jump (activateNextAttentionEntry, kept). Removed the screen and its a key from the union, statusline tabs, nav cycle, dispatch, render switch, footer + help, and host state. Persisted activity falls back to the dashboard.

Phase 2 — Graveyard: surface graveyardedAt. The worktree detail showed Last Used but not when the worktree was graveyarded — added a "Graveyarded · N ago" line. The other two items from the original audit were verified false/already-handled and are noted in the commit (the detail-index "desync" can't occur — nav stays within selectableRows and the detail is guarded; orphan-teammate rows are already labelled "missing parent" and non-selectable).

Final screen set

Dashboard (untouched) · Coordination · Project · Library · Topology · Graveyard. Keys: i coordination · y project · p library · t topology · g graveyard; u next-attention on the dashboard.

Verification

• yarn typecheck, yarn lint, yarn build clean
• yarn vitest run — 1397 tests pass

📝 Walkthrough

Walkthrough

The "activity" dashboard screen is removed end-to-end: its type is dropped from DashboardScreen and related models, its exported functions are deleted from subscreens.ts and dashboard-actions-methods.ts, its "a" key bindings are removed from all key handlers and routing paths, and its TUI renderer is deleted. Keycap hint strings across all subscreen footers are updated accordingly. A new "Graveyarded" timestamp field is added to the graveyard worktree detail pane.

Remove Activity Dashboard Screen

Layer / File(s)	Summary
Type and model contracts: remove activity, add help src/dashboard/state.ts, src/dashboard/ui-state-store.ts, src/statusline-model.ts	DashboardScreen union drops "activity"; VALID_SCREENS whitelist removes "activity"; StatuslineData.dashboardScreen removes "activity" and adds "help"; DASHBOARD_SCREEN_TABS removes the activity tab entry.
Core implementation: remove activity state and exports src/multiplexer/index.ts, src/multiplexer/subscreens.ts, src/multiplexer/dashboard-actions-methods.ts	Removes activityEntries and activityIndex fields from Multiplexer; deletes four exported activity-dashboard functions (getActivityEntries, showActivityDashboard, renderActivityDashboard, handleActivityKey) from subscreens.ts and their corresponding dashboardActionMethods wrappers; drops the renderActivityScreen import.
Key handling and routing: remove activity dispatch src/multiplexer/dashboard-control.ts, src/multiplexer/dashboard-interaction.ts, src/multiplexer/navigation.ts, src/multiplexer/session-launch.ts, src/multiplexer/runtime-state.ts	Removes the "a" key case from handleDashboardSubscreenNavigationKey, handleDashboardKey, and handleHelpKey; removes the activity-screen stdin routing branch from runDashboard; removes the "activity" early-return branch from renderCurrentDashboardView.
TUI rendering: remove activity screen, update hints, add graveyard detail src/tui/screens/subscreen-renderers.ts, src/tui/screens/dashboard-renderers.ts, src/tui/screens/overlay-renderers.ts, src/tui/screens/subscreen-renderers.test.ts	Deletes renderActivityScreen; updates d/a/... keycap hints to d/i/... in coordination, project, topology, graveyard, and library footers; adds conditional Graveyarded timestamp to graveyard detail pane; removes [a] activity from buildHelpLine and buildHelpOverlayOutput; adds test for graveyard detail timestamp.

Poem

🐇 Hop, hop — the "activity" tab is gone,
No more [a] key to press along!
The graveyard now shows when things died,
A timestamp added with bunny pride.
Keycap hints now say d/i instead,
Clean code, clean keys — the past is shed! 🪦
