[Bug]: rollback ("edit from here") silently hidden in non-git workspaces, conversation-only rewind blocked too #17187
Description
Activity
The silent hiding is two separate gates: the conversation rewind target comes from the server (
typeof revertTurnCount === "number"inapps/web/src/components/chat/MessagesTimeline.tsx), while file restore is separately gated on a worktree and refused when the directory is shared with another thread or session (docs/user/composer.md, "Edit an earlier prompt").So a non-git workspace loses the conversation-only rewind as well, even though that part needs no file restore. If the workspace gate is deliberate, a disabled control with a tooltip would at least explain the omission instead of showing only "Copy message".

That was on me, not useful.
One thing I still can't tell from the report: in the non-git folder, does "Edit from here" come back if you
git initthat same folder while T3 is open, or only after reopening the thread? That would say whether the workspace check happens when the card is drawn or once per thread, which changes where the fix goes.Reacted by Eliott Scherrer

Area
apps/server
Steps to reproduce
same driver (pi), same account, in a git-backed workspace (project repo or t3 worktree) the button shows up on hover and rollback works. so it's workspace dependent, not driver dependent
Expected behavior
rollback should work, at least conversation-only ("revert and keep changes", restoreFiles: false) which doesn't need a file checkpoint in the first place. or at least tell me why it's unavailable instead of silently hiding the button
Actual behavior
no rollback at all in non-git workspaces:
CheckpointCaptureServiceV2(apps/server/src/orchestration-v2/CheckpointService.ts:381, also :342) stores checkpoints withstatus: "missing"whenisGitCheckpointable(cwd)is falsereadycheckpoints into the per-messagerevertTurnCountthat gates the "edit from here" button (deriveRevertTurnCountByUserMessageId,apps/web/src/session-logic.ts:1045)so in a scratch (non-git) workspace the whole rollback feature is dropped, including "revert and keep changes" which is conversation-only and doesn't need any file checkpoint
also: the only "Roll back" button for checkpoint items (
apps/web/src/components/chat/V2ItemInspector.tsx:376, gated onstatus === "ready") renders from timeline rows'projectedItem, but the timeline entry builder skips checkpoint items entirely (apps/web/src/session-logic.ts:631), so that button is unreachable from the timelineImpact

No response
Workaround
none in-app. running the conversation in a git-backed project (or git init-ing the workspace folder) makes checkpoints "ready" and the button shows up for subsequent turns. conversation-only rewind really shouldn't need a git repo at all tho?
