Problem

With related checkouts grouped in the default sidebar, Settings → Project → Checkouts had no per-checkout grouping control. A checkout could not be split into its own project there, or restored to the global rule after being split.

Change

Restore the existing four grouping choices on every checkout, including single-checkout projects. Persist changes through the client-settings update queue using the same override keys as the legacy dialog; inheriting removes only the selected override. Existing navigation follows the checkout when its current group empties.

Save failures display an error toast and retain the saved selection. Accessible names include the environment label and full ID. Checkout controls stack at narrow widths; a lone checkout keeps its removal action in Danger. The legacy dialog shares the labels and override helper.

Scope and approval

Fixes https://git.cafe/pingdotgg/t3code/issues/16445

Triaged bug via the automated issue flow: #16445. This restores an existing client setting removed from project settings by #10639; it adds no contract, server, schema or native-client behavior.

Verification

At f822473:

• Focused ProjectSettingsPanel logic tests: 3/3 passed. Targeted lint, formatting and web typecheck passed. All32 reported CI checks passed; both independent full code reviews returned MERGE. Macroscope approved and CodeRabbit reports no actionable findings.
• Real-app checks cover grouping/inheritance, preservation of other overrides, scoped split/return navigation, two environments with the same path, keyboard interaction, reduced project permissions, legacy Save/restore and both persistence-rejection messages.
• Independent corrected proof audit: SUFFICIENT. All112 comparison counts/masks were independently verified. One exact-path head rebuild matched with0 changed pixels at both thresholds.

Captioned scoped round trip: select Keep separate, observe automatic navigation while retaining scope, then Use global default and observe automatic return. Captions distinguish source checkpoint/wall-clock time from compressed playback. The base counterpart shows the absent control.

Visible changes: the helper and grouping selectors add height; Remove controls shift, nested rows stack, and narrow paths/default labels truncate. The failure toast overlays the upper settings content at narrow width. Wide legacy-dialog and breadcrumb glyph raster differences are disclosed per row; no claim of zero unrelated pixel changes is made. Historical invalid/contaminated comparisons are excluded, with provenance retained in the linked reports. Web content used by desktop is covered; no native Electron-shell change or mobile grouping override was introduced. All owned capture/audit servers are stopped.

Approvability

Verdict: Approved at bd84f03

Macroscope's review found this PR approvable — Project settings now let users change or reset each checkout’s sidebar grouping rule, including for a lone checkout. The change uses existing client preferences, leaves defaults and permissions unchanged, and is reversible through the same selector.

Walkthrough

Project settings now provide grouping selections for individual checkouts, persist valid selections as overrides keyed by physical project, and show an error toast if saving fails. The Checkouts section now appears for projects with one or more checkouts.

Changes: Per-checkout grouping

Layer / File(s)	Summary
Grouping override helper apps/web/src/sidebarProjectGrouping.ts	The module exports labels for grouping modes and a helper that removes an override for inherit or sets the selected mode in a copied override map.
Project settings checkout controls apps/web/src/components/settings/ProjectSettingsPanel.tsx	Each checkout has a grouping selector with validated options. Selections are persisted by physical project key. The controls retain conditional checkout removal, and the Checkouts section is always rendered.

Dismissing prior approval to re-evaluate f822473

[juliusmarminge]

Fixed both CodeRabbit findings in f822473: failed grouping saves show an error toast and retain the saved selection; accessible names include the environment label and full ID.

Focused logic tests: 3/3 passed. Targeted lint, format and web typecheck passed. Both independent code reviewers returned MERGE.

Integrated check: real web dev app, Chromium 154 on Linux, DPR 2, no device emulation, 390×844 dark. A synthetic persistence rejection followed by choosing Keep separate leaves the inherited rule and empty override map intact and displays the error. Recording: 0s open select, approximately 1s choose Keep separate, approximately 2s toast and unchanged selection.

mcp-launch-client-3a7a0b3e00-f428-46f3-ad82-685d92fda730-fwd-3a06b9743a2ae6c9f9f-9b59d720-74a6-4172-9f7c-1261c06313ef-mp4.mp4

Independent proof reconciliation remains INSUFFICIENT: historical capture SHAs are preserved, final-head matrix coverage, paired failure evidence, duplicate-path accessibility interaction, keyboard/permission action coverage and fixture reproducibility remain open. R4/R5/R6 threshold counts use 8/255 (3.1373%), not the global 8% caption. The previous blanket SUFFICIENT statement should not be used for the current head. CI and bot checks must run again on this push.

[juliusmarminge]

Corrected capture set delivered for f822473: report and complete comparison tables. It replaces the active proof selection with matched clock/origin/scroll frames, labelled Danger anchors, and captioned interaction variants. Historical invalid trials remain excluded.

Fixed-path fixture and stills · Source and captioned recordings.

Independent audit of this corrected set is running. Verification remains open; production source is unchanged.
