Correction to the inline review suggestion: the opening and closing tag edits belong to the same hunk; the intervening child markup should remain unchanged. Posted via Macroscope — UI Consistency |
Contributor
ApprovabilityVerdict: Not approved Macroscope's review found this PR not approvable — This focused web UI change introduces independent collapse controls and previews for reasoning traces, changing the default visibility of thoughts when a tool group is opened. The implementation is isolated, but the changed product default warrants human review. You can add or adjust custom eligibility rules. Learn more. |

Merges `pingdotgg/t3code` `6d1d549441..9946541` (50 commits) into the fork. Landed 304 files against 303 in the upstream range — the extra one is `docs/fork/inventory.json`. Fork delta is 777 files, unchanged from the last merge. Everything upstream changed landed. Six conflicts, each resolved with the verdict `preflight.mjs` printed; five were a single hunk. Details and reasoning are in [the merge tracker](docs/fork/upstream-merge-log.md). The two worth reading here: - **`ChatView.tsx`** — pingdotgg#12306 added `activeWorktreePath !== null` to the "Revert files too" button, on the line the fork gates with `FEATURES.checkpointFileRestore`. Kept both as a conjunction: upstream's condition is about a shared workspace, the fork's is about what Moatless serves, and they answer different questions. - **`FilePreviewPanel.tsx`** (the one `decide`) — pingdotgg#10909 restructured the file read so a folder is knowable as a folder, adding `isDirectory` / `previewPath`. Took that whole and re-stated the fork's `onRetargetFile` effect on top. `apps/web/src/routeTree.gen.ts` was regenerated rather than hand-resolved. One judgement call: pingdotgg#11598's new `/settings/storage` page is deliberately **not** given a `FEATURES` gate. It self-gates on two new capability booleans Moatless does not report and renders an explanatory notice, so a fork flag would duplicate a decision the wire already makes — and would have to be deleted again the day the capability is reported. ## Usable as-is - Diff files open from a right-click context menu (pingdotgg#11842). - Sidebar filtering from the thread menu (pingdotgg#8719). - Command palette matches thread IDs (pingdotgg#11185). - Mobile settings are easier to navigate and scope (pingdotgg#12272); favorites in the mobile model picker (pingdotgg#12231). - Thoughts collapse within tool groups (pingdotgg#12302); thoughts and failed tool calls stay in one activity row (pingdotgg#12270). - Folder links from chat open the file tree instead of a broken preview (pingdotgg#10909). - Chat no longer jumps when the scroll-to-end pill mounts (pingdotgg#12317); numbered jumps no longer steal browser tabs (pingdotgg#12315); composer banners stay compact (pingdotgg#12166). - A large batch of shared-component refactors across web and mobile (pingdotgg#12353–pingdotgg#12371). ## Unsupported in Moatless / needs implementation - **Pull request files marked as viewed** (pingdotgg#7721) — adds `pullRequests.filesViewed` and `pullRequests.setFilesViewed`, which record which files a reviewer has checked off, persisted server-side. Both declare `PullRequestRpcError` and so arrived already refusing; `unsupported-methods.mjs` reported ADD 0 / DROP 0 as a result. Closes with the rest of the `pullRequests.*` group, not separately. - **Multi-model threads in separate worktrees** (pingdotgg#12179) — one prompt starts a thread per selected model, each in its own worktree. The model picker is the same `worktree` send-mode control `FEATURES.worktreeSelection` already gates, so the fan-out is simply not offered. The same commit adds a `requiredWorktreeBootstrap` capability the backend does not report. - **Automatic storage cleanup settings** (pingdotgg#11598) — the `/settings/storage` page, gated by the backend's absent `storageCleanup` and `projectWorktreeCleanup` capabilities. Needs the sweeper below before the page means anything. - **Command palette entries for the pull requests and usage pages** (pingdotgg#12211) — the PR half is covered by `FEATURES.pullRequestSurface`. ## Backend behavior to consider reproducing in Moatless Eight items, recorded in full in [the gaps register](docs/fork/gaps.md) under _Runtime fixes upstream made to its own server_. Five are on the checkpoint and usage paths the previous merge already opened: - **Reject a file rewind on a shared or nested-owner cwd** (pingdotgg#12306, `CheckpointReactor.ts`) — a checkpoint holds the whole checkout, so restoring one erases a sibling's uncommitted work. Moatless isolates by sandbox, but a workspace with nested repositories has the same overlap inside one task. - **Capture a checkpoint when the baseline lookup fails** (pingdotgg#12307) — the case that silently leaves a turn with no restore point. - **Move the file-search refresh off the checkpoint path** (pingdotgg#12308) — it extended every capture by an index walk. - **Survive an empty nested repository, and clear a stale index lock** (pingdotgg#12181, `GitVcsDriver.ts`) — git cannot stage an embedded repository until it has a commit. The lock half matters most here: forced termination is the normal end of a sandboxed task. - **Bound the provider event log before serialization** (pingdotgg#12305, `EventNdjsonLogger.ts`) — otherwise it grows proportionally to tokens streamed. - **Keep usage totals across transcript cleanup** (pingdotgg#12304, `UsageService.ts`) and **resolve a contested fingerprint to the newest scan** (pingdotgg#10315, `usageMerge.ts`). Moatless serves `server.getUsageSummary` itself. - **Pass provider image attachments by path** (pingdotgg#11050, `CodexAdapter.ts`) — the turn/start request stops scaling with attachment size. A sandbox adds a hop, so an oversized request costs more there. - **Sweep stale worktrees and transcripts against retention rules** (pingdotgg#11598, `storageCleanup.ts`, with a workspace lease so two servers cannot sweep the same directory). A sandbox per task bounds the worktree half; transcripts outlive the sandbox. ## Verification `verify.mjs` — all 9 checks green on the first full pass, tests included (333 test files, 5071 tests). No flaky retries and no caveats. Contract drift: ADD 0 / DROP 0, so `packages/contracts/src/rpc.ts` needed no change. The `orchestration-decode-boilerplate` duplicate-add exception went stale — the colliding line is gone — and was deleted from `inventory.json` in this merge. Owned-concern sweep: the three new `apps/mobile/src/features/connection/` files are false positives, all upstream extracting shared mobile components out of files it already owned, with no fork delta in any of them. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --- Moatless task: https://moatless.soaplabstest.com/tasks/c83db5aa-7c47-47c6-93f4-fe2f6f9f548e

opening a tool group currently reveals every reasoning trace. thoughts now stay collapsed independently, showing a truncated reasoning preview and a chevron; expanding a thought reveals its full text and restores the thought label. thought-only groups retain their existing single disclosure.
validation: web typecheck and 120 existing timeline tests passed on blacksmith; targeted lint completed with 20 warnings and no errors. verified collapse, expansion, and restored previews in the web client using a real Claude thread through the shared server.
model: gpt-6; harness: codex.
Spacing follow-up: collapsed thought headers now match the 24px tool rows, with no extra gaps between thought and tool sections. Verified expansion and collapse in an isolated web client with synthetic transcript data. Web typecheck and 173 focused timeline tests pass; targeted lint has warnings and no errors.
