ApprovabilityVerdict: Not approved Macroscope's review found this PR not approvable — This is a substantial cross-platform feature that introduces a managed Chats project, per-conversation filesystem state, provider/terminal routing, and broad changes to existing project and Git flows. It also changes startup defaults and has an unresolved workspace-environment isolation finding affecting server-chat terminals. Adjust the Minimum Blocking Severity for this repo — including turning it Off — in Settings. You can add or adjust custom eligibility rules. Learn more. |

returned identity map applies the CHAT_PROJECT_ID guard when mapping each

project shares its workspaceRoot. Preserve existing workspace-root deduplication
and repository identity resolution for all other projects.

- Line 8435: Update the keyboard shortcut handler in ChatView so every
rightPanel.* and terminal.* branch is additionally gated by !isChat ||

while preventing chat drafts from toggling or modifying unavailable panels.

resolveDefaultThreadEnvMode to classify chat projects using projectRef.projectId
even when project is absent, before the project-dependent branch and
global-default lookup; preserve explicit options.envMode handling, and add a
regression test covering an absent chat project record.

New threads show the saved project name and icon in a title chip. The icon reveals a remove action on hover or keyboard focus; removing it enters chat mode without losing the prompt. The Chat picker restores project context, and the machine selector chooses which connected environment runs the chat. A server-managed Chats collection keeps each conversation in its own
<t3-home>/chat/<thread-id>folder, using the existing session path for Codex, Claude, Cursor, Grok, OpenCode, and Antigravity.Web, desktop's shared web UI, and mobile offer the removable chip and omit project git/scripts controls. Draft switching preserves the prompt and clears worktree choices; chat files, assets, terminals, resume, and copy-path use the conversation folder.
Validation: typechecks passed for contracts, client-runtime, server, web, and mobile; 205 web, 127 server/shared, and 16 mobile focused tests passed. Scoped lint passed with existing warnings. The title revision passed web/mobile typechecks, 206 web tests and 10 mobile selection tests on Blacksmith. Manual switching between two isolated servers on the same host preserved the chat prompt, and Codex answered from the second server's managed chat directory. Automatic routing preserves the draft's environment ownership. Hover reveal and native mobile rendering are runtime-unverified; preview automation has no hover action. In the real web client, Codex answered a question, reopened the conversation, and answered a follow-up using the same persisted directory. Other providers and native mobile interaction are unverified at runtime. Also verified per-chat terminal cwd, T3CODE_PROJECT_ROOT, and file-picker isolation; 66 provider-reactor tests cover failures including a chat folder replaced by a file.
Implemented with GPT-6 in the Codex harness.
