Cause: the new sidebar's empty state (Sidebar.tsx) was rendered only when pinned+active+working+snoozed+settledCount was 0, so a project scope whose project had only settled threads left a blank Working area with just the Settled shelf and the small favicon/initials badge as the only sign of the filter, which looks like lost data. Fix: the empty state moves above the thread list. It shows when no pinned/active/working/snoozed threads are visible and either nothing is settled or a scope is active. With a scope it reads 'No active threads in ' ('these projects' for several) when settled threads remain, or the existing 'No threads in yet' otherwise, plus a 'Show all projects' button that calls the same setProjectScopeKeys([]) as the picker's All projects. Unscoped behaviour, including 'No projects yet' / Add project, is unchanged. Verified in the web dev app on a fresh database (T3CODE_DEV_SEED=0) with projects alpha (2 Replay threads) and beta (1 thread, settled): scoping to beta showed the message and button above 'Settled 1', and clicking the button emptied sidebarProjectScopeKeys and brought back the alpha and server threads. Visible-change rationale: the 'before' contradicts the app itself, which already shows 'No threads in X yet' when a scope hides everything but showed nothing once any settled thread remained; this is the reporter's and second commenter's 'looks like everything is gone'. No new regex or parser.

Fixes #16692

Reproduction on main

Commit f03db4f (origin/main). Web dev app started with T3CODE_DEV_SEED=0 vp run dev on a fresh database. Added two git projects, alpha and beta, with t3 project add, and started 3 free Replay (dev) threads with t3 thread start --provider devReplay --model showcase (2 in alpha, 1 in beta). Settled the beta thread from its sidebar row. Opened the new sidebar's project filter (icon next to Search); it offered All projects, beta, alpha, server. Picked beta. Result: the Working area is blank with no empty-state text, the only visible item is 'Settled 1', and the only sign of the filter is a 16px 'BA' initials badge in place of the filter icon. The two active alpha threads and the server thread are hidden. Opened beta's settled thread and reloaded: the scope persisted (sidebarProjectScopeKeys held the beta key) and the sidebar was still empty apart from Settled 1. Reopening the picker and choosing All projects cleared the filter, so the 'cannot clear' part did not reproduce. On main, a reload or navigation that lands on a thread outside the scope clears the scope (route reveal); that happened on my first reload. A remote scratch 'No project' scope and multiple remote environments were not exercised: a fresh database has no scratch project in the picker. The underlying mechanism is the same for any scoped project.

Evidence

Environment for every capture: real web dev app in headless Chromium, 1280×800, light theme, fresh isolated database per commit, T3CODE_DEV_SEED=0, synthetic projects and free replay turns.

Steps: Create alpha, beta, gamma and delta; start two replay threads in alpha and one in beta. Settle beta from its sidebar row. Select beta; expand Settled, open its thread and reload. Shift-select gamma alongside beta. Select gamma alone, then Shift-select delta. Capture each scoped empty state. Clear through Show all projects on head (All projects picker fallback on base) and capture both alpha threads restored.

Proven: the final scenario fails on base and passes on head. Base lacks the scoped explanation when settled threads exist and lacks Show all projects in all four scoped empty states. Head displays the appropriate singular/plural message and recovery button throughout.

Runnable scenario source

Recordings omit initial pairing and fixture cleanup; the reproduction itself is continuous. Every still and transition recording was visually inspected. AI-assisted; verified with the tests and tools listed above.

Not shown:

  • Remote scratch “No project” scopes and multiple connected environments were not exercised; the proof covers the shared scope behavior using local git projects.
  • Desktop shell and mobile clients were not exercised; the changed component is the web sidebar.

Tests

vp run check:changed: pass (format, lint, knip 2/2, typecheck of 2 packages, tests in 7 files, react compiler). vp run typecheck in apps/web: 0 errors. Manual check in the web dev app via the preview browser as described in the summary.

Not in this change

  • A persistent 'Scoped to · Clear' chip shown while the scope is active even when active threads are visible (a redesign suggested on the issue).
  • Resetting or refusing a persisted scope that points at a scratch 'No project' project, or keeping scratch out of the scope picker.
  • Making the closed filter trigger easier to tell apart from a project favicon when a scope is active.

AI-assisted; verified with the tests and tools listed above.

… offers Show all projects

The sidebar empty state was skipped whenever any settled thread was visible,
so a scope on a project with only settled threads looked like lost data.
Show it whenever a scope leaves no active threads, above the Settled shelf,
with a button that clears the scope.

Approvability

Verdict: Approved at a2f61f0

Macroscope's review found this PR approvable — The sidebar now explains when a project filter leaves no active threads and offers Show all projects. The button reuses the existing filter-reset action without changing defaults or underlying thread data.

Walkthrough

The sidebar now displays an empty state when a selected project scope has no threads or has settled threads but no active-category threads. The text varies by scope size, and the scoped empty state offers a “Show all projects” button.

Changes: Scoped sidebar empty state

Layer / File(s) Summary
Render scoped empty states
apps/web/src/components/Sidebar.tsx
The empty state distinguishes scopes with no threads from scopes with settled threads but no active-category threads. It varies the wording for one or multiple selected projects and adds a “Show all projects” button. The existing “No projects yet” message and add-project action remain. The expanded block replaces the previous empty-state block.

Merge Risk: Low · up to a2f61

In boring sidebar mode, the new "No active threads" message and "Show all projects" button do not appear when a scoped project has only settled threads, so the fix does not apply to that mode. The scope can still be cleared from a thread-row menu, so the impact is limited. Standard sidebar mode is unaffected.

Explanation

The title names the main change: a project filter that hides every active thread now shows an explanatory empty state with a Show all projects button. It uses the conventional commit form with the web scope. It matches the Sidebar.tsx change and the linked issue about a hidden scope.

Full details: Out of Scope Changes check

Explanation

The reviewed change is limited to apps/web/src/components/Sidebar.tsx (+45/-31 per the summary). It moves and extends the existing empty state so that it appears when a scope hides all pinned, active, working, and snoozed threads and settled threads remain. It adds a 'Show all projects' button that reuses setProjectScopeKeys([]). These changes connect directly to the scope-related empty-state behavior in #16692. The unscoped empty state ('No projects yet', Add project) is unchanged as stated. No unrelated files are reported in the summary. The summary did not list test-file changes, so test coverage of the new branch is not established by this review.

Full details: Description check

Explanation

The description covers the problem (empty state hidden when a scoped project has only settled threads), the change (empty state moved above the thread list, scoped and unscoped messages, Show all projects button), scope (links issue #16692 as the bug), and verification (reproduction on main, before/after evidence, check commands). It follows the template closely. Minor gaps: the title line is absent from the description, and the template's 'Solve one underlying problem' scope note is addressed only indirectly. The 'Not shown' and 'Not in this change' sections add useful context.

Full details: Linked Issues check

Explanation

Issue #16692 has two coding requirements that this PR covers only in part. (1) Clear way to reset a scope: covered for the empty case. The new empty state in Sidebar.tsx shows a 'Show all projects' button that calls setProjectScopeKeys([]). (2) Expected behavior 'if a project scope is active, it should be obvious in the sidebar': not covered when active threads are visible. The PR description states that a persistent scope indicator is out of scope. With a scope active and threads visible, the only sign of the filter is the small favicon or initials badge on the picker trigger. The issue also asks that a scope pointing to a scratch 'No project' be validated or reset. The PR does not implement this and states it is out of scope. The 'cannot clear' report did not reproduce on main per the PR description, so the clear-button requirement is partly met by existing behavior and the new button. The PR's own verification covers only a local project with a settled thread, not a remote scratch project.

Resolution

Add a visible active-scope indicator (for example 'Scoped to <project> · Clear') that displays whenever a scope is active, including when pinned, active, or working threads are visible. Also validate or reset a persisted scope that refers to a scratch or non-visible project, as the issue requests. Then verify both behaviors in the app, including a remote scratch scope if available.

3320-3323: Trivial · Maintainability & Code Quality · Low value

Extract the repeated sidebar recovery-button classes.

The "Show all projects" button repeats the full class string of the "Add project" button in the same empty state. Both controls must change together when the sidebar style changes. Move the shared classes into a sidebar-local component or a named constant in Sidebar.tsx, then use it for both buttons.

No Button variant in components/ui/button.tsx matches this look, so the primitive does not fit. The sidebar-specific tokens and text-2xs belong to the sidebar feature.

Minor · Functional Correctness · Quick win

Show the scoped empty state in boring sidebar mode.

In boring mode, a scoped project keeps its folder even when it has no active threads. That keeps hasProjectFolders true, so the new block above the Settled shelf does not render. The user gets no "No active threads" message and no "Show all projects" button at that point. The only other route to clear the scope is the thread-row menu item.

Allow the block when a scope is set, even if folders exist:

Suggested fix

-          !hasProjectFolders &&
+          (!hasProjectFolders || scopedProjectGroups.length > 0) &&

Unscoped boring mode is unchanged, because scopedProjectGroups.length is zero there. Add a boring-mode case with a scoped project that has only settled threads to Sidebar.browser.test.tsx.

[Bug]: New sidebar silently stuck on a remote 'No project' scope, so all projects and Working threads appear missing
