fix(projects): group non-Git copies across environments explicitly - #23531
A non-Git project whose repositories live in child directories cannot use T3 Code's existing cross-environment project grouping. Its repositoryIdentity is null, so the same registered folder appears once per environment. SDK and SpacetimeDB folders replicated to three environments each therefore appear as six projects instead of two logical projects with three checkout targets each.
Related report: #22663 (converted to a discussion). This PR uses explicit identity assignment rather than matching directory names or paths.
Change
Add an optional groupingIdentity, a lowercase UUID v4 stored with each physical project's metadata and application events. Git repository identity retains precedence; projects without an explicit identity keep the existing physical grouping fallback, and Separate mode stays separate.
Carry the metadata through project create/update, persistence, shell snapshots, RPC/HTTP, and the existing MCP project tools. Null clears it; omission preserves it.
Add t3 project add <root> --grouping-identity <uuid> for both new registrations and existing roots, plus t3 project grouping <root> [--identity <uuid> | --clear] and JSON t3 project list for inspection. Repeated assignment preserves physical IDs, titles, paths, and threads. Registration and grouping workflows run in ProjectService through the authenticated project mutation transport for both live and offline CLI commands.
Use the shared logical grouping policy in mobile's environment matching as well as the existing web/desktop and mobile grouping consumers. Same-named unrelated directories are not an identity signal.
No group directory is initialized as a Git repository, and RepositoryIdentityResolver remains Git-derived. The contract, server, CLI/MCP, shared client behavior, regression tests, and user documentation address the same grouping failure. Private fleet-manager integration is outside this public PR; it can call the supported CLI with operator-selected UUIDs and approved machine/path mappings.
Scope and approval
This is submitted under CONTRIBUTING.md's focused configuration option for an established capability: T3 Code already combines physical projects across environments and offers repository, repository-path, and separate grouping modes. This option supplies an explicit grouping key for roots that cannot have a Git repository identity. It adds no automatic name/path merging and does not change grouping defaults. The CLI and MCP entry points assign the same optional grouping key; client environment routing resolves the selected logical group to an existing physical copy. These paths support the same grouping option rather than separate workflows. No upstream maintainer approval is claimed from the related report; eligibility under the exception remains a maintainer decision.
Verification
Rebased on upstream main at a6d769506444, preserving all 44 published commits. Verified on macOS with Node 24.14.0. Current head: 1559524366.
vp run check:changed upstream/main
On current head 1559524366, vp run check:changed upstream/main passed: format/lint, both knip passes, generated GraphQL checks, all 37 affected-package/dependent typechecks, all 1,953 tests across 24 selected files (including migration upgrades, exact context budget, and mobile compiler coverage), and the additional targeted web compiler check. No repository-wide tests or typechecks were run.
The branch preserves main’s mobile “Work on PR” fix: switching between known copies of the same Git repository retains the PR workspace, while non-Git copies and different repositories do not satisfy that Git-only guard. Explicit non-Git identity matching, canonical grouping, Separate mode, and unrelated-host rejection remain intact. The existing selection cases retain the same-Git assertion and verify that explicit non-Git copies and different Git repositories fail the worktree-preservation guard. No unrelated feature changes were added.
Grouping is migration 94, after main’s migration 93 (ProviderTurnAttemptIndex), preserving migrations 90 (AuthConnectDevices), 91 (AuthConnectDeniedRequests), and 92 (QueuedTurnInputIndexJsonValid). The direct 93→94 and both preview-upgrade regressions preserve main’s migrations, project data, custom-title flags, pin/archive timestamps, migration history, and idempotence. The exact context-budget test verifies the real instructions and schemas against 5,930 Claude-system bytes, 7,324 Codex-context bytes, and 49,747 MCP-tool bytes (main’s tool budget is 49,749).
On preceding head 1048aa70ee, a disposable-state source-CLI run applied migration 90, registered a non-Git workspace with an identity, repeated assignment, rejected a duplicate without the flag, inspected the UUID, cleared it, and listed one project with the same physical ID and a null identity. This remains earlier-head runtime evidence.
Hosted CI passed on current head 1559524366, including both web shards, all eight server shards, build/typecheck, lint, package tests, release smoke, and the aggregate Check. Agent Context Budget, the primary fingerprint check, size labeling, and CodeRabbit also passed. A duplicate fingerprint run was cancelled; conditional jobs and previews were skipped, which are not execution passes. CodeRabbit reviewed this head with no actionable comments. Its summary’s possible clear-identity eval gap was checked against the current source: the case requires an explicit identity argument and null value, and existing regressions reject omission, undefined, and an unchanged UUID. This evidence was posted, along with a request to resume automatic reviews after they paused. Historical browser and independent runtime evidence applies only to the heads it names. Live model eval comparisons remain unverified because API/proxy credentials are unavailable; offline grader tests do not establish live model behavior. Native mobile and packaged Electron were not launched for this update. Auto-merge remains disabled and the PR is left unmerged. Eligibility under the focused configuration exception remains a maintainer decision; no maintainer approval is claimed.
Focused tests cover six physical projects across three environments becoming two groups; distinct UUIDs and unrelated same-name directories staying separate; Separate mode and per-project overrides; Git precedence during enrichment; clearing without stale metadata resurrection; CLI updates preserving physical IDs and existing threads; and consistent duplicate-aware environment routing in shared web/mobile logic. The routing regressions failed before their fixes. Tests also cover rejecting unrelated environment switches. Native mobile and packaged Electron were not launched.
Four synthetic project cases in evals/mcp-tool-use/cases/projects.ndjson cover reuse of an existing lowercase grouping UUID across environments, Git identity precedence, clearing the key, and title-only creation effects. Both Claude and Codex dry runs build the four grouping requests and upstream's archive-project request from this checkout's real schemas. The archive case and the four existing grouping cases were preserved exactly during conflict resolution. The update and clear cases restrict top-level arguments. The clear case also requires an explicit null identity; omission cannot earn clearing credit. The Git-precedence case requires the correct direction and an explanation that the projects cannot be merged this way. The title-only preview rejects shell Git initialization and requires affirmative Git-initialization, scaffold, and commit disclosure, rejecting initialization denials. Negation checks stay within sentence boundaries, with positive examples distinguishing a safe preview from post-approval creation. Two existing grader tests were extended and failed before these fixes. Offline regression traces reject extra metadata fields, shell initialization, and negated disclosures that the prior cases accepted. Seven additional incorrect explanations reproduced the latest findings before the expectation changes and are rejected afterwards, alongside passing active/passive disclosures and safe pre-approval previews. These are grader checks, not model results. A live Sonnet baseline attempt stopped because ANTHROPIC_API_KEY is unavailable; the Codex eval proxy is also unconfigured. Before/after model comparisons and full per-model eval runs remain pending. No live model pass or failure against the old text is claimed.
Independent Linux runtime verification
Maria reported runtime verification of the preceding head 7b82a2b5a against main 955e2bfbb5, using the real web client and real Codex turns. The report covers grouping through the live CLI, switching drafts in both directions between two isolated server environments, selected physical project IDs and workspaces, clearing/restoring identities, Git precedence, Separate mode, unrelated-folder rejection, and persistence across a dev-server restart. It includes before/after captures and a cross-environment recording. This is independently reported evidence on that earlier head, not a runtime pass on the current rebased head.
Both servers ran with separate state and ports on one Linux VM. Native clients, other operating systems/providers, relay, and physically separate machines were not verified. These runtime turns do not replace the pending live model eval comparisons described above.
Browser evidence (captured before this rebase)
Three disposable local servers represent separate environments; the Windows host runs all three fixtures. Project roots were registered and updated through t3 project add, not database writes. With identities cleared, Settings showed three SDK and three SpacetimeDB rows. Assigning the same SDK UUID on all three and a different shared SpacetimeDB UUID reduced them to one row each. Opening SDK still listed all three environment-specific checkouts. The new-thread project picker showed one SDK entry, and its Run context menu offered all three environments. The additional Git project stayed grouped as before.
Before identity assignment (reproduces the previous behavior):
After explicit identity assignment:
SDK retains all three physical checkouts:
Native mobile and packaged Electron were not launched; their shared grouping logic and mobile environment selection were covered by focused tests and typechecks. Installed clients/servers were not updated or restarted, and live databases were not modified. Rollout requires updating the server/CLI and clients before assigning identities; servers apply migration 92 on startup.

Walkthrough
Projects can store an explicit grouping identity for non-Git copies. The project service and CLI support setting, inspecting, and clearing identities. Client grouping and environment selection use resolved project groups, while Git repository identity retains precedence.
Changes: Project Grouping Identity
Layer / File(s)
Summary
Identity contracts and persistence packages/contracts/*, apps/server/src/orchestration-v2/*, apps/server/src/persistence/*, packages/client-runtime/src/operations/commands.ts
Project contracts, events, commands, and client inputs carry optional nullable groupingIdentity. Server storage persists the value, and migration 94 adds the nullable grouping_identity column.
Project registration and identity management apps/server/src/project/*, apps/server/src/cli/project*, apps/server/src/orchestration-v2/*test.ts, apps/server/src/relay/AgentAwarenessRelay.test.ts, packages/contracts/src/settings*
The project service and mutation dispatcher add registration and grouping operations. The CLI adds project list and project grouping, and project add accepts --grouping-identity. Tests cover identity validation, updates, clearing, and registration conflicts.
Logical keys and scratch-scope resolution now include explicit grouping identities. The client can resolve a project’s group while retaining repository identity precedence.
Mobile and web environment selection use resolved project groups. Mobile environment switching now reports failure when no matching project exists, and its tests cover grouped copies and separate grouping mode.
Project tool behavior and guidance apps/server/src/mcp/toolkits/project/*, apps/server/src/provider/agentContextBudget.json, evals/mcp-tool-use/*, docs/user/project-settings.md
MCP descriptions and handling cover grouping identity behavior. Evaluation cases and grading cover identity updates, Git precedence, and project-creation explanations. The guide documents CLI and agent-tool operations.

The change adds explicit grouping identities for non-Git projects. Runtime behavior appears sound. One eval-grader gap may remain, where a clear-identity case can pass without clearing. This is a low-impact test-quality follow-up.

The title "fix(projects): group non-Git copies across environments explicitly" matches the main change: an explicit grouping identity that groups non-Git project copies across environments. It is a conventional commit title in plain language and names the primary change, so it passes.
Full details: Description check
Explanation
The description follows the repository template closely. It has Problem, Change, Scope, and Verification sections, and each is substantively filled. The Problem section states the non-Git grouping failure and links related report #22663. The Change section lists the contract, server, CLI/MCP, client, and docs changes. The Scope section explains the focused-configuration exception from CONTRIBUTING.md and says no maintainer approval is claimed. The Verification section lists commands run, the environments used, the tests added, and the limits of what was checked (native mobile and packaged Electron not launched, live model evals pending). The description is long and dense, and it includes material better suited to the PR comments, such as CI run history and extended eval-grader details. Those points do not block the check. The Scope section also leans on an exception argument that a maintainer must decide.

A failed-jobs rerun was attempted, but GitHub requires repository admin rights. This needs a maintainer rerun or an upstream action repair; no project-grouping code ran in the failed step. The local check:changed upstream/main run passed all stages, including 170 tests and 29 affected-package/dependent typechecks. The other five workflows remain awaiting maintainer approval.
Use the duplicate-aware key map for environment routing.
For a newest record with repositoryIdentity: null and groupingIdentity: G, this hook derives G. The shared grouping code can derive R from an older duplicate with repositoryIdentity: R. The hook then omits the R environment. The web picker and automatic environment balancing can be lost.
Use buildPhysicalToLogicalProjectKeyMap for the active project and each candidate.

Use collection-aware identities for mobile new-task matching.
resolveEnvironmentProjectMatch and resolveNewTaskEnvironments compare direct per-record keys. If the newest record has repositoryIdentity: null and groupingIdentity: G, while an older duplicate has repository identity R, buildProjectGroups assigns the physical project the R key. The mobile functions still derive G, so the matching R environment can be omitted. selectEnvironment then returns false and leaves the selected environment unchanged.
Integrate this consumer with buildProjectGroups or an equivalent collection-aware adapter. The pending-project fallback does not fix normal grouped-project matching.

Carry nullable groupingIdentity through the pending-task queue.
Project.groupingIdentity accepts null. If the queued schema uses Schema.optional(Schema.String) and the enqueue condition checks only !== undefined, explicit null is forwarded and rejected by the queued-message codec. Use Schema.optional(Schema.NullOr(Schema.String)), add null to the queued type, and preserve the value on the placeholder.

Addressed all three outside-diff findings from this review in 6056e04d9:
Web environment routing and mobile matching/candidate selection now share resolveProjectGroup. It resolves the physical record through buildProjectGroups, retaining inherited Git identity from duplicates while using the newest saved metadata, and returns the winning physical records. A per-record key is used only when the selected project is absent from the collection. Regression coverage includes Git enrichment and a cleared explicit identity.
Mobile queued-task creation now stores optional nullable ProjectGroupingIdentity, and the pending-project placeholder restores it. The existing queue had no grouping field, so the reproduced defect was dropped metadata rather than the hypothetical String-only codec rejecting null. New round-trip tests verify both UUID and null; the mobile routing regression verifies the full collection is used.
The three new regression cases failed before the fixes. After rebasing onto upstream main at 6e7921174, check:changed upstream/main passes all stages, including 213 tests across 18 files and 30 affected-package/dependent typechecks.
Please keep automatic reviews enabled for future maintenance rebases. Current head 155952436678c9143d1a5ebbf252a876bc19db09 passed CI and Agent Context Budget.
The summary’s possible clear-identity grader gap is already covered on this head: clear-non-git-grouping-identity requires groupingIdentity through requiredArgs and expects its value to be null. matchesCall rejects undefined/missing required arguments. The existing regression at evals/mcp-tool-use/run.test.ts:450 rejects omission, explicit undefined, and an unchanged UUID, while accepting explicit null. These grader tests passed in the current-head changed-file run; this is not a live model eval claim.
@djgilcrease I’ll resume automatic reviews for future maintenance rebases.
Thank you for clarifying the clear-identity grader coverage and the distinction from live model evals.

Problem
A non-Git project whose repositories live in child directories cannot use T3 Code's existing cross-environment project grouping. Its
repositoryIdentityis null, so the same registered folder appears once per environment. SDK and SpacetimeDB folders replicated to three environments each therefore appear as six projects instead of two logical projects with three checkout targets each.Related report: #22663 (converted to a discussion). This PR uses explicit identity assignment rather than matching directory names or paths.
Change
Add an optional
groupingIdentity, a lowercase UUID v4 stored with each physical project's metadata and application events. Git repository identity retains precedence; projects without an explicit identity keep the existing physical grouping fallback, and Separate mode stays separate.t3 project add <root> --grouping-identity <uuid>for both new registrations and existing roots, plust3 project grouping <root> [--identity <uuid> | --clear]and JSONt3 project listfor inspection. Repeated assignment preserves physical IDs, titles, paths, and threads. Registration and grouping workflows run inProjectServicethrough the authenticated project mutation transport for both live and offline CLI commands.No group directory is initialized as a Git repository, and
RepositoryIdentityResolverremains Git-derived. The contract, server, CLI/MCP, shared client behavior, regression tests, and user documentation address the same grouping failure. Private fleet-manager integration is outside this public PR; it can call the supported CLI with operator-selected UUIDs and approved machine/path mappings.Scope and approval
This is submitted under CONTRIBUTING.md's focused configuration option for an established capability: T3 Code already combines physical projects across environments and offers repository, repository-path, and separate grouping modes. This option supplies an explicit grouping key for roots that cannot have a Git repository identity. It adds no automatic name/path merging and does not change grouping defaults. The CLI and MCP entry points assign the same optional grouping key; client environment routing resolves the selected logical group to an existing physical copy. These paths support the same grouping option rather than separate workflows. No upstream maintainer approval is claimed from the related report; eligibility under the exception remains a maintainer decision.

The routing regressions failed before their fixes. Tests also cover rejecting unrelated environment switches. Native mobile and packaged Electron were not launched.
Four synthetic project cases in
evals/mcp-tool-use/cases/projects.ndjsoncover reuse of an existing lowercase grouping UUID across environments, Git identity precedence, clearing the key, and title-only creation effects. Both Claude and Codex dry runs build the four grouping requests and upstream's archive-project request from this checkout's real schemas. The archive case and the four existing grouping cases were preserved exactly during conflict resolution. The update and clear cases restrict top-level arguments. The clear case also requires an explicit null identity; omission cannot earn clearing credit. The Git-precedence case requires the correct direction and an explanation that the projects cannot be merged this way. The title-only preview rejects shell Git initialization and requires affirmative Git-initialization, scaffold, and commit disclosure, rejecting initialization denials. Negation checks stay within sentence boundaries, with positive examples distinguishing a safe preview from post-approval creation. Two existing grader tests were extended and failed before these fixes. Offline regression traces reject extra metadata fields, shell initialization, and negated disclosures that the prior cases accepted. Seven additional incorrect explanations reproduced the latest findings before the expectation changes and are rejected afterwards, alongside passing active/passive disclosures and safe pre-approval previews. These are grader checks, not model results. A live Sonnet baseline attempt stopped becauseANTHROPIC_API_KEYis unavailable; the Codex eval proxy is also unconfigured. Before/after model comparisons and full per-model eval runs remain pending. No live model pass or failure against the old text is claimed.Independent Linux runtime verification
Maria reported runtime verification of the preceding head
7b82a2b5aagainst main955e2bfbb5, using the real web client and real Codex turns. The report covers grouping through the live CLI, switching drafts in both directions between two isolated server environments, selected physical project IDs and workspaces, clearing/restoring identities, Git precedence, Separate mode, unrelated-folder rejection, and persistence across a dev-server restart. It includes before/after captures and a cross-environment recording. This is independently reported evidence on that earlier head, not a runtime pass on the current rebased head.Both servers ran with separate state and ports on one Linux VM. Native clients, other operating systems/providers, relay, and physically separate machines were not verified. These runtime turns do not replace the pending live model eval comparisons described above.
Browser evidence (captured before this rebase)
Three disposable local servers represent separate environments; the Windows host runs all three fixtures. Project roots were registered and updated through
t3 project add, not database writes. With identities cleared, Settings showed three SDK and three SpacetimeDB rows. Assigning the same SDK UUID on all three and a different shared SpacetimeDB UUID reduced them to one row each. Opening SDK still listed all three environment-specific checkouts. The new-thread project picker showed one SDK entry, and its Run context menu offered all three environments. The additional Git project stayed grouped as before.Before identity assignment (reproduces the previous behavior):
After explicit identity assignment:
SDK retains all three physical checkouts:
Native mobile and packaged Electron were not launched; their shared grouping logic and mobile environment selection were covered by focused tests and typechecks. Installed clients/servers were not updated or restarted, and live databases were not modified. Rollout requires updating the server/CLI and clients before assigning identities; servers apply migration 92 on startup.
