Problem

A repository group can contain a project at the repo root (app) and a project for a subfolder of the same repo (app/reference/design). If the group's checkouts also disagree on the repository name's casing, every sidebar thread in the group is labelled design, including threads that belong to app. Casing can differ because each clone keeps the casing of its own remote URL (for example Owner/App on one machine and owner/app on another). The breadcrumb and the project icon still show the right project.

deriveProjectGroupLabel tries a shared title, then a shared display name, then a shared repository name. If none of those match, it falls back to representative.title, which is one member's folder name.

Change

The final fallback now uses the representative's repository display name, then its repository name, and only then its title. Every member of a repository group shares that repository, so its name describes the whole group. The title remains the last resort for groups without a repository identity. The first three steps are unchanged.

The fix is in packages/client-runtime, so web and mobile both get it.

Scope

This is a small fix for an obvious bug: the sidebar names the wrong project. Open PRs #29111, #25244 and #33642 change the earlier steps of the same function. None of them changes this fallback.

Verification

• Found on a daily install (0.1.7 Beta). Desktop and a remote environment were both connected, with a root project and a subfolder project in the same repo. Every thread in the group was labelled with the subfolder's name.
• I added a regression test with a subfolder project, its repo-root project, and a clone on another environment whose display name and repository name use different casing. On main it fails with Expected: "T3 Code", Received: "design-study". With the fix it passes, and so do the other 22 tests in projectGrouping.test.ts.
• vp lint on the changed files and typecheck for @t3tools/client-runtime are clean.
• Not checked: I didn't run the patched build against the original two-environment setup. The mismatched casing on the remote clone is inferred from the code path; the remote checkout wasn't inspected directly.

Approvability

Verdict: Approved at be920fc

Macroscope's review found this PR approvable — Grouped projects now prefer a repository name over an individual folder title when member names disagree. The change affects display labels without changing grouping membership or operation targets.

Walkthrough

Repository group labels now use repository identity when the group key matches the repository’s canonical key. Settings screens pass the group key to label derivation, and one settings label path now requires a selected project.

Changes: Repository group label

Layer / File(s)	Summary
Repository label fallback and tests packages/client-runtime/src/state/projectGrouping.ts, packages/client-runtime/src/state/projectGrouping.test.ts	Label derivation checks the repository display name, then repository name, before using the representative project title for a canonical repository group. Tests cover “T3 Code,” “Design docs,” and “t3code” labels.
Settings label derivation apps/mobile/src/features/settings/SettingsProjectOverviewRouteScreen.tsx, apps/mobile/src/features/settings/SettingsRouteScreen.tsx	The project overview passes the group key to label derivation. The settings index derives a label only when a project is selected and scoped members exist.

Merge Risk: Low · up to 6408b

Grouped repositories get the repository label in the common case. In a rare mix of an identity-less newest project and clones with differing name casing, the group can still show a folder name. This is cosmetic and can be fixed in a follow-up.

Full details: Title check

Explanation

The title names the main change: grouped projects in client-runtime no longer use one member's folder name as the group label. It follows the conventional commit format and matches the raw summary, which shows the fallback in deriveProjectGroupLabel now uses the repository display name, then repository name, before the representative title. The title is specific and scannable.

Full details: Description check

Explanation

The description follows the template. It has Problem, Change, Scope, and Verification sections, and each contains specific content. The Problem section gives the bug and its cause. The Change section explains the new fallback order and why it is correct. The Scope section links related open PRs and explains why no issue is linked. Verification names a regression test, the observed failure and pass, lint and typecheck results, and what was not checked. Gaps: the Scope section does not link an issue or state a maintainer request, and it gives a reason for the missing issue. The template asks for a link to an issue or a reason, and the reason is given. The verification section has no UI screenshots, which is acceptable because the change is in non-UI runtime logic. The description is mostly complete.

Minor · Functional Correctness · Quick win

Use the grouping identity for whole-repository group labels.

When the winning project lacks repositoryIdentity, buildProjectGroups takes the group key from an identified duplicate through selectProjectIdentitySource. The identity-less winner still becomes a group member and can become the representative. If the identified clones disagree on casing, the shared-name checks in deriveProjectGroupLabel do not return. The representativeIdentity && guard then fails, and the group keeps the representative's folder title.

Pass the identity that produced groupKey into the label calculation instead of reading it from the representative. Extend the existing test at projectGrouping.test.ts:412 with casing-disagreeing clones to cover this path.
