The +N chip was not positioned while each SubagentAvatar is relative, so the browser painted the avatars above it regardless of DOM order. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Taking over this one. I’ll reduce the tests to the useful coverage, update the implementation against current main, and verify it before publishing the changes. |

Merges upstream `pingdotgg/t3code` at `143ab1606d` (base `ab6be13d43`, 376 commits) into the fork. No merge PR was open, so this branches from `main`. ## Merge - **Landed:** 1177 files out of 1177 in the upstream range. The only missing files are `apps/server/src/cli/pair.ts` and its test, which the fork deliberately keeps deleted. The fork delta is now 817 files. - **Conflicts:** 14, each resolved by its `preflight.mjs` verdict. The tracker entry in `docs/fork/upstream-merge-log.md` covers each one. The ones a reviewer should read: - **`ProjectDefaultsSettings.tsx`:** upstream moved the agent-browser-access row to `IntegrationsSettings.tsx` (`AgentBrowserAccessSetting`). The fork's `workspaceOwnsProjectDefaults` gate moved with it and returns null at a Workspace project scope. - **`terminal.ts`:** keeps the fork's `TerminalMetadataState` seed and takes upstream's `Stream.drop(1)`. Upstream's new `runtime.test.ts` metadata test now reads `.terminals`. - **`Sidebar.tsx` / `Sidebar.logic.ts`:** upstream's new `resolveSidebarRowThreadId` resolves against the unfiltered shells. It now takes `source`, because the fork's `isSidebarSubagentThread` hides only provider-native subagents. - **`ChatView.tsx` (auto-merged):** the fork's hosted script path calls `storeSetActiveTerminal` again. The local path drops its early `setTerminalOpen(true)`, following upstream pingdotgg#18340, so the drawer no longer claims the default terminal id. - **`AGENTS.md`:** keeps the fork's prose and adds upstream's new `Effect.fn` rule. - **`apps/mobile/package.json`:** takes upstream's test script and keeps `tsc` rather than `tsc-rs`. - **`pnpm-lock.yaml`:** `tsc-rs` entries stripped, then re-derived with `install.mjs`. - **Other fixes:** - `fork/goToDefinition.test.ts` moved to browser mode for upstream's new `no-dom-test-environment` lint rule. - `ThreadDetailsPrRows.browser.test.tsx` now passes `activeProjectScriptsEditable`. - One new `duplicateAddExceptions` entry was added and one stale one retired. - **Unsupported methods:** ADD 0, DROP 0, KEEP 2. `packages/contracts/src/rpc.ts` is unchanged. ## Verification `verify.mjs --sequential`: - duplicate-adds, tripwires, resolution-check, unsupported-methods, lockfile, fmt, lint, typecheck and build all pass. - `test` fails. The files that fail when run alone are the same five as on 2026-10-19 (`AgentScope`, `OpenCodeServerLedger`, ssh `tunnel`, `AcpAdapterV2`, `OrchestratorReplayFixtures`), all sandbox process-reaping or auth issues. - Two new failures are also environmental: the partial-clone tests in `GitVcsDriver.test.ts` and `RepositoryIdentityResolver.test.ts`. The sandbox's `~/.gitconfig` rewrites `git@github.com:` to https with `insteadOf`. - `@t3tools/web` had one real failure, upstream's new Sidebar subagent test. It is fixed and passes on its own. **Caveat:** the last amend changed only that test fixture and the docs. The sandbox restarted three times during this run, and the typecheck and fmt re-run after that amend did not finish. A follow-up comment will report it. ## Usable as-is - LaTeX/KaTeX math in chat markdown, behind the client setting `mathRenderingEnabled` in Appearance, off by default (pingdotgg#18735). - Mermaid renders while a message streams (pingdotgg#18308). Large changed-file trees are virtualized (pingdotgg#21482, pingdotgg#21831). HTML previews skip the loading skeleton (pingdotgg#21480). - Pasted folders become workspace references (pingdotgg#22072). PR check rows aligned, and skipped checks get a slash icon (pingdotgg#22090, pingdotgg#21498). A confirmation before "Close with comment" (pingdotgg#18175). - Subagent overflow badge (pingdotgg#19860). Context usage survives a fork (pingdotgg#22075). Copy paths relative to the thread workspace (pingdotgg#21497). PDF preview (pingdotgg#21095). - Contract decoding tolerates newer PR shapes (`ForwardCompatibleArray` / `ForwardCompatibleOptional`; pingdotgg#19899, pingdotgg#21575, pingdotgg#21665). - In-app browser search engine settings (pingdotgg#17688). These are client-only, but they only matter where the browser panel is exposed. ## Unsupported in Moatless / needs implementation - **`thread.stop` and `capabilities.threadStop` (pingdotgg#22052):** stops a thread without resolving its run. The client falls back to the existing stop path until the backend advertises `threadStop`. Added to the capabilities gap. - **`blocking: false` on async questions (pingdotgg#15430):** keeps a thread Working while a question is open. The backend has to emit the field. - **Provider `optionDescriptors` / `installedVersion` (pingdotgg#19519, pingdotgg#19567):** drive dynamic model options and update checks. Both are optional, so the client degrades. - **Terminal `resume: true` on resubscribe (pingdotgg#18444):** the backend should not reopen a closed shell. - **`rootPath` on git diff/status results:** used for workspace-relative paths. - **`repositoryWebUrl` on PR links (pingdotgg#21575).** - **Relay, T3 Connect, hosted sign-in and `t3 update` work:** not applicable to the single-origin Moatless deployment. ## Backend behavior to consider reproducing in Moatless - **Settlement:** an empty inactive thread auto-settles (pingdotgg#15783). Settling clears snooze (pingdotgg#17547). An interrupted run does not start the settle timer on a snoozed thread (pingdotgg#17789). - **Runs:** auto-delivered messages queue between provider turns (pingdotgg#15691). A message promoted into a stopping run stays queued (pingdotgg#16926). Compaction cadence survives restarts (pingdotgg#21880). - **ACP:** native foreground work settles independently, and child routing moves between runs (pingdotgg#21614–pingdotgg#21616). Delegated children stop once (pingdotgg#18826). - **Terminals:** slow clients no longer queue unbounded output (pingdotgg#18429). Shells do not inherit tmux (pingdotgg#13359). Script commands stay out of shell history (pingdotgg#13903). - **Files:** saves no longer follow a symlink out of the workspace (pingdotgg#18819). This one is security-relevant. - **Git:** new worktrees fetch the base branch's own tracked remote (pingdotgg#21032). Rename and non-ASCII paths are kept in changed-file lists (pingdotgg#20175). Rollback blocked by an index lock now says so (pingdotgg#11340). The `docs/fork/gaps.md` entries "Capabilities are reported…" and "Runtime fixes upstream made to its own server" are extended with these. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --- Moatless task: https://moatless.soaplabstest.com/tasks/d311aafc-7a38-48b7-9c14-30c4cac930a7

Problem
When a turn has more than three subagents, the overflow count paints behind the third avatar and is partly hidden.
Change
Position the overflow chip with
relative, so it paints after the positioned avatars in DOM order. This is one class change; avatar layout, status dots, disclosure behavior and memoization remain unchanged.Scope and credit
Credit to PollyGlot for the original fix in #19860. Original contributor commits are retained, with current main integrated by merge. Web and desktop share this renderer; native mobile uses a separate sibling stack.
