ApprovabilityVerdict: Not approved Macroscope's review found this PR not approvable — This PR introduces a substantial cross-provider rewind workflow spanning durable provider history, filesystem checkpoints, session recovery, attachments, and composer state, including destructive changes to existing conversations and workspaces. The supplied prompt-restoration concern appears addressed in the examined head, but the breadth and side effects still require human review.

Merges `upstream/main` at `e81606494` into the fork, from merge base `02297e3db` — 47 upstream commits. The theme of this range is scopable settings: upstream made every server setting addressable at a scope (global / environment / project) with per-project overrides, which is why 11 of the 15 conflicts are settings files. The rest is conversation rewind, floating device streams, and a large batch of message-sync and markdown-streaming perf work. ## Merge stats - Landed (`HEAD^1..HEAD`): 277 files, 17243+/4783− - Upstream range (base..`HEAD^2`): 275 files, 17011+/4749− - Fork delta (`HEAD^2..HEAD`): 756 files, 76559+/2096− The two file lists reconcile: the 3 extra landed files are `docs/fork/inventory.json`, `docs/fork/upstream-merge-log.md` and `docs/fork/gaps.md`; the 1 file in the range that did not land is `apps/web/src/routes/settings.integrations.tsx`, resolved `ours` per the `moatless-admin-integrations-route` inventory entry (that route is a Moatless admin page here, and upstream's embedded-surface settings live at `/settings/browser`). All 15 conflicts were resolved by the verdict `preflight.mjs` printed. No `decide` conflict was left unresolved. Details, including the owned-concern sweep (no keyword hits) and the unsupported-method reconciliation (0 ADD, 0 DROP, 2 KEEP, 4 known exceptions), are in the dated entry in `docs/fork/upstream-merge-log.md`. Two findings worth naming here: - **A silent auto-merge failure.** pingdotgg#11285 changed the mini-player target from a tab id to a source union. Git updated upstream's own assertion in `PreviewView.test.tsx` and left the fork-only "under the frame capability" case next to it still asserting the old string. No conflict marker, no `resolution-check.mjs` finding — only the fork's own test suite caught it. - **Stale inventory anchors.** Upstream moved the project Actions section out of `ProjectSettingsPanel.tsx` into a new `ProjectActionsSettings.tsx`, which is where `scriptsEditable` is now derived and where upstream's new writing Reset button is gated. Four inventory entries were re-pointed in this merge rather than silently dropping their deltas. ## Usable as-is Client work the fork can expose with no Moatless backend change: - Scoped settings UI and the two-select scope picker (pingdotgg#10639, pingdotgg#10636) — `SettingsScopeContext`, `ScopedSwitch`, `settingKeys`, the `mixed` state. The reading half works against Moatless today. - Float device streams over chat, as a source union rather than a tab id (pingdotgg#11285); recording status on floating previews (pingdotgg#11312); floating preview using composer margins (pingdotgg#11290). - PR-page selections into new drafts (pingdotgg#11296); projects-on-another-machine badge (pingdotgg#11323); Usage opening on Limits (pingdotgg#11261). - macOS permission onboarding (pingdotgg#11289); hold-to-quit fix (pingdotgg#11016); preview keystrokes kept out of the composer (pingdotgg#11354). - Message-sync and markdown-streaming perf: pingdotgg#11302, pingdotgg#11029, pingdotgg#11211, pingdotgg#11198, pingdotgg#11196, pingdotgg#11193, pingdotgg#11181, pingdotgg#11206. - Assorted web/mobile fixes: pingdotgg#11361, pingdotgg#10757, pingdotgg#11357, pingdotgg#10571, pingdotgg#11348, pingdotgg#11349, pingdotgg#11281, pingdotgg#11188, pingdotgg#11283, pingdotgg#11292, pingdotgg#11187, pingdotgg#11228, pingdotgg#11103, pingdotgg#10612, pingdotgg#11032, pingdotgg#11233, pingdotgg#11234, pingdotgg#11304, pingdotgg#11240. ## Unsupported in Moatless / needs implementation - **Conversation rewind** — `thread.conversation.revert` (pingdotgg#11358). A new member of `DispatchableClientOrchestrationCommand` in `packages/contracts/src/orchestration.ts`, bringing the fork to 30 command types (28 upstream's, 2 fork-only). Moatless does not dispatch it, and a client command cannot be refused per-type, so "Edit from here" on `RevertUserMessageButton` is reachable whenever the turn is idle and does nothing. Needs backend dispatch. - **Per-project setting overrides** — the `projectSettingsOverrides` capability and the 17-key `ProjectSettingsOverrides` record (pingdotgg#11176). Two pieces are needed: the capability reported by `/.well-known/t3/environment`, and `server.updateSettings` served at project scope. Until both land, the capability filter in `scopedSettings.ts:170` and `ProjectActionsSettings.tsx:72` drops the write on the client — the control renders, the user toggles it, and **the write never leaves the browser**. A silent no-op is worse than a hidden control or an honest refusal; recorded in `docs/fork/gaps.md`. - **Default thread permissions** — `defaultRuntimeMode` (pingdotgg#11346). Reads fine, cannot be saved. Same `server.updateSettings` write path as above, one level deeper, not a separate gap. ## Backend behavior to consider reproducing in Moatless Upstream server-side work the fork cannot use directly, but that Moatless would benefit from: - **Queue messages during context compaction** (pingdotgg#11107, `ProviderCommandReactor.ts`) — a message sent while compaction is in flight is currently dropped rather than held. - **Restore provider history and prompts when rewinding** (pingdotgg#11338, `CheckpointReactor.ts`) — the counterpart to `thread.conversation.revert` above; rewinding the thread without rewinding provider state leaves the two out of sync. - **Detect file renames in review diffs** (pingdotgg#8086, `apps/server/src/vcs/GitVcsDriverCore.ts`) — a rename currently reads as a whole-file delete plus a whole-file add. - **Preserve qualified Codex model ids** (pingdotgg#9921, `ModelManifest.ts` + `CodexTextGeneration.ts`). - **Model defaults** astra-medium / fable-5.1-medium (pingdotgg#11347). All five are recorded under the runtime-fixes entry in `docs/fork/gaps.md`. ## Verification `verify.mjs` (full pass): 7 of 8 checks green — `duplicate-adds`, `tripwires`, `resolution-check`, `unsupported-methods`, `fmt:check`, `lint`, `typecheck`. `test` is red on **`@t3tools/desktop` only**, at `scripts/browser-secret-native.test.mjs > bundled libsecret helper`: `Command failed: pkg-config --cflags --libs libsecret-1`. This is the standing sandbox gap, not a merge regression — the test file's last commit is `498ab9c39` (pingdotgg#7261, before the merge base), `git diff --name-only` against both merge parents is empty for it, and `pkg-config --exists libsecret-1` fails in this environment. It is already an entry in `docs/fork/gaps.md`. Every other package passes, including `@t3tools/web` (5079 tests) after the `PreviewView.test.tsx` fix above. Three typecheck failures the merge introduced were fixed in it: `SETTINGS_CATEGORY_SCOPES` in `settingsSearch.ts` was missing all 9 fork-only settings paths, and two `filterAvailableSettingsSearchItems` literals in `settingsSearch.test.ts` were missing the fork's `forgejoEnabled` field. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --- Moatless task: https://moatless.soaplabstest.com/tasks/e70b41b3-779d-43b8-8f34-7de516548e7c

Edit from here rewinds files and provider history to before the selected message, then restores its prompt and attachments to the composer for editing and resending. Existing drafts are preserved. Attachment bytes are saved before rewind deletes their old copies, then uploaded afresh; matching filenames do not discard either attachment. Sending and attachment changes pause until rewind completes, including across thread navigation.
Rollback uses Codex's paginated
thread/revertAPI and forks Claude's durable history at the retained T3 turn, including turns with steering and background responses. Rewinds recover inactive sessions after restart, persist replacement session IDs and native boundaries, and restore empty filesystem checkpoints. Claude's history helper is bundled for custom homes in packaged servers; ambiguous older or compacted history is rejected rather than truncating at an uncertain boundary. Cursor and Grok no longer offer rewind because their ACP sessions do not support it; Cursor now rejects the operation instead of reporting a local-only success.Verified real Codex, Claude, and OpenCode (Big Pickle) conversations, rollback, and follow-up context; Claude also restored an edited file. Cursor and Grok answered real questions and retained follow-up context with rewind unavailable. Antigravity is not installed. Focused existing adapter, orchestration, and git suites, server typecheck, and scoped lint passed. An isolated server bundle read and forked real Claude history without installed dependencies. The added steering/recovery regressions pass; a further live steering conversation was blocked by Claude's session limit (reset 02:20 UTC), after the earlier real conversation verification succeeded. The Codex recording retains error activities from the reproduced failures; its final rewind and answer succeed. Claude's external auto-memory files are outside the workspace rollback and can retain removed information.
Verified the composer interaction through real Codex and OpenCode conversations: Codex restored an image and text file, then answered the edited prompt using both; OpenCode restored the selected prompt beneath an existing draft and answered the edited resend. All 298 focused web tests passed, plus web typecheck, scoped lint, and formatting. Additional live Claude verification remains blocked by its session quota.
The confirmation explains the rewind and composer restoration in two short sentences. Opened and cancelled the real dialog; scoped formatting and lint passed.
Restored prompts use the existing prompt-history cleanup so attachment-only bootstrap text and generated context do not enter the composer. Verified a real Codex attachment-only question and rewind; all 16 existing prompt-history tests pass.
Implemented with GPT-6 in Codex.
