The docstring-coverage warning is advisory. This change adds no public API, and docstring-only edits are outside this focused bug fix. The changed behavior is covered by the regression tests, so I am leaving that style suggestion unchanged. |

Merges `upstream/main` at `0c5771d60` into the fork, from merge base `e81606494` — 32 upstream commits. The range is mostly client polish, plus two structural changes that mattered here: upstream extracted the sidebar header into a new component (`SidebarThreadHeader.tsx`, pingdotgg#11315), which is where two fork gates had to be re-homed, and upstream added a `context` field to orchestration messages at the exact anchor the fork's `origin` field sits on, which is four of the eight conflicts. ## Merge stats - Landed (`HEAD^1..HEAD`): 489 files, 36117+/5930− - Upstream range (base..`HEAD^2`): 484 files, 35784+/5824− - Fork delta (`HEAD^2..HEAD`): 767 files, 78724+/2528− The two file lists reconcile exactly. The 5 extra landed files are all fork-owned and none of them is upstream work: `apps/web/src/fork/SidebarThreadFilter.tsx` (one className, described below), `docs/fork/inventory.json`, `docs/fork/gaps.md`, `docs/fork/upstream-merge-log.md`, and `.agents/skills/fork-upstream-merge/scripts/unsupported-methods.mjs`. Nothing in the upstream range failed to land. ## Conflicts All 8 were resolved by the verdict `preflight.mjs` printed. No `decide` conflict was left unresolved. - `projector.ts`, `orchestration.ts`, `threadReducer.ts`, `MessagesTimeline.tsx` — `converged — message-origin-upstream-files`, and all the same conflict: upstream appended where the fork already appends. Both sides kept, twice per file for the first three. `duplicate-adds.mjs` confirms no line was taken twice. - `Sidebar.tsx` — `converged — thread-visibility-upstream-files`. Took upstream whole; its `SidebarThreadFilter` import was left unused by the extraction and was removed. - `SettingsSidebarNav.tsx` — unlisted. Kept the fork's `settingsPathEnabled` filter over the personal nav items and took upstream's new active-state rule (`/settings/general` stays active on `/settings/open-source-licenses`). - `ChatComposer.tsx` — unlisted, so `decide, then add an entry`. Both fork deltas survived and the entry is now written; see below. - `routeTree.gen.ts` — generated; regenerated with `regen-route-tree.mjs` after the install. `pnpm-lock.yaml` auto-merged rather than conflicting, so it was reset to `upstream/main` and the fork edges re-derived with `vp i`. The remaining diff against upstream is exactly the `@t3tools/moatless-api` workspace link, `mermaid ^11.17.2`, and one alchemy peer hash. Two findings worth naming here: - **A fork gate's host file was replaced by a file upstream had not written yet.** pingdotgg#11315 extracted the whole sidebar header into `apps/web/src/components/sidebar/SidebarThreadHeader.tsx`. Both fork deltas were re-applied there additively — the `FEATURES.projectManagement` gate on New project, and `<SidebarThreadFilter />` as a third child of upstream's new segmented icon well. No props threaded, no state added, no upstream JSX re-indented. The one edit outside that file is `SidebarThreadFilter.tsx`'s trigger className, now `size-7` so it matches upstream's own `SidebarHeaderIconButton` in the well it now sits in. - **The unsupported-method derivation could not read the backend, and that was the script's fault, not a finding.** `unsupported-methods` exited 2 with "could not read the backend dispatch". The Moatless backend moved its dispatch a second time: `crates/t3code/src/rpc/dispatch.rs` is now a module stub over an `rpc/dispatch/` directory whose `routing.rs` holds the arms and whose siblings hold the handler bodies. `BACKEND_APIS` now names the directory and the script concatenates every `.rs` file in it — pointing it at `routing.rs` alone would have read the arms and lost the handlers, and `refusesInside` only follows calls it can find in the same source, so every conditional refusal would have come back as a false DROP. ## Inventory - `moatless-admin-pages` was stale: it still listed the two Workspaces admin routes that the 2026-09-12 commit folded into the project settings page. Re-pointed to the five surfaces that remain, and the untracked delta that move left behind is now its own entry, `project-workspace-settings`. - `chat-surface-gates` gained `apps/web/src/components/chat/ChatComposer.tsx` with a guard on `FEATURES.accessMode`, plus a `chat-composer-gates` path policy so the next merge gets a cached verdict instead of the same decision. The two deltas there are the runtime-mode picker lifted into a `runtimeModePicker` const behind the flag, and `phase === "running"` left out of `collapsedComposerPrimaryActionDisabled`. - `inventory-check.mjs` is clean. ## Unsupported methods 0 ADD, 0 DROP, 2 KEEP (`git.preparePullRequestThread`, `vcs.switchRef`), 5 known exceptions still firing, no stale ones. `packages/contracts/src/rpc.ts` is unchanged: the range's one unsupported-surface change is upstream's Cursor `--classic` launcher fix, which lands on a method already refused. ## Feature classification ### Usable as-is Client-side work the fork can expose with no Moatless backend or deployment change. 28 of the 32 commits. - Open-source license notices page (pingdotgg#8962) — new `/settings/open-source-licenses` route; upstream also made `/settings/general` stay active while it is open. - Client perf: fewer repeated sorts and date formats (pingdotgg#11019). - Inline file previews and attachment chips across surfaces (pingdotgg#11265) — rides `attachments.createUploadUrl` and `assets.createUrl`, both dispatched. - Subagent spawns as an expandable work row (pingdotgg#11433) and those rows kept visible under folded turns (pingdotgg#11474) — derived from the orchestration event stream the backend already serves. - Opt-in thread notifications and sounds (pingdotgg#11481) — client settings, persisted through the `server.getSettings` read the backend serves. - Large pastes folded into text attachments (pingdotgg#11442); user input kept outside collapsed work (pingdotgg#11363); each chat message exposed as a heading for screen readers (pingdotgg#11199); the default diff file state (pingdotgg#11484). - Sidebar project scope folded into the search row (pingdotgg#11315); thread status icons completed and input threads kept prominent (pingdotgg#11461); sidebar search and footer spacing (pingdotgg#11466); draft row heights matched to thread rows (pingdotgg#11512). - Image chips tinted with their average colour (pingdotgg#11468); viewer controls moved outside the media with arrow navigation restored (pingdotgg#11470); snapshot preview size preserved in sent messages (pingdotgg#11429); preview focus preserved on window return (pingdotgg#11444). - Unavailable account limits made more visible (pingdotgg#10601) — web-only; the backend dispatches `server.getUsageSummary`. - Saved environments switched off instead of removed (pingdotgg#11478) — entirely client-side (connection catalog and registry). This build runs one environment and gates the Connections settings page, so nothing on screen changes; the catalog behaviour carries. - Desktop and mobile: long offscreen text in SnapShots (pingdotgg#11250), native preview User-Agent kept for Turnstile (pingdotgg#7110), bounded backend shutdown wait on quit (pingdotgg#7599), expo-audio pinned (pingdotgg#11426), photo library picks rendered to a bounded JPEG off the JS thread (pingdotgg#11440), launch crash with a PR stack (pingdotgg#11486), the shared-content alert after sending (pingdotgg#11487). - Repository hygiene: `.pnpm-store/v11` deleted. ### Unsupported in Moatless / needs implementation - **Cursor links open in classic IDE mode (pingdotgg#11498).** Upstream gave Cursor `baseArgs: ["--classic"]` in `packages/contracts/src/editor.ts` so a file open targets the IDE rather than its Agents Window, and tested it in `apps/server/src/process/externalLauncher.ts`. The method behind it, `shell.openInEditor`, is not dispatched — the browser is not on the machine the workspace is on — so this lands in the contract and in `apps/server` and changes nothing here. Recorded in `docs/fork/gaps.md` under _Opening in an external editor_, whose standing conclusion is that the surface is a candidate for deletion rather than for serving. ### Backend behavior to consider reproducing in Moatless All three are recorded in `docs/fork/gaps.md` under _Runtime fixes upstream made to its own server_. Nothing in this repository holds them open; they are Moatless-side work. - **Listing pull requests should read only the projects asked about (pingdotgg#11299).** `listWorkspaceProjects` fetched the whole shell snapshot and filtered it; it now asks the projection for the one project, or for the listed ids (`apps/server/src/pullRequest/PullRequestService.ts`, `persistence/Layers/ProjectionSnapshotQuery.ts`). Moatless dispatches `pullRequests.summary`, so the same cost lands on it as soon as a summary is derived from a list. - **Usage should read each provider account's own history directory (pingdotgg#11485).** Upstream resolves an account's home from its home setting or its `CODEX_HOME` / `CLAUDE_CONFIG_DIR` / `GROK_HOME` variable, counts disabled accounts, and de-duplicates accounts sharing a directory (`apps/server/src/usage/UsageService.ts`). Moatless serves `server.getUsageSummary` itself, so an account with a custom home reports zero there — or double — until it resolves homes the same way. - **Forgejo and Gitea remotes should be first-class source control (pingdotgg#11436).** Upstream recognises both hosts and drives them with the `fj` and `tea` CLIs across remote identity, PR creation and PR sync (`git/GitManager.ts`, `project/RepositoryIdentityResolver.ts`, `orchestration/PullRequestSyncReactor.ts`). Moatless owns git and pull requests, so a Forgejo or Gitea project is an unrecognised host there regardless of what the client can render. ## Verification `verify.mjs` is green on seven of eight checks: `duplicate-adds` (none across 34 files both sides changed), `tripwires` (3 deleted surfaces intact, exactly the 5 known re-deletions, 3 allowed workflows), `resolution-check` (16 fork-delta paths still differ from upstream, 17 carry upstream's change, 17 theirs-verbatim byte-identical, 18 unlisted), `unsupported-methods`, `fmt:check`, `lint`, `typecheck`. `test` is red on one file, and it is the standing environmental failure rather than a merge regression: - `@t3tools/desktop` → `scripts/browser-secret-native.test.mjs > bundled libsecret helper` fails with `Package 'libsecret-1' not found` from `pkg-config`. 1 file of 105; the rest of the package is 1341 tests passed. The test file is byte-identical to upstream, arrived on the fork before this merge, and the sandbox image ships neither `libsecret-1` nor its pkg-config file. There is no root in the sandbox, so it cannot be installed here. Recorded in `docs/fork/gaps.md` under _The desktop suite needs libsecret, which the sandbox does not have_. Four packages did not finish under `vp run -r test` and were each run alone again, all green: `@t3tools/mobile` (165 files, 1528 tests), `t3` (317 files, 4528 tests), `@t3tools/web` (412 files, 5205 tests), `t3code-relay` (30 files, 284 tests). The owned-concern sweep over newly added upstream files found no keyword hits, so no `concerns` entry was needed. **CI caught one thing no local check runs.** `Build & push moatless-t3` failed on the first push: upstream's new `t3code:third-party-licenses` plugin (pingdotgg#8962) runs in `generateBundle` and refuses any bundled package whose license it cannot resolve, and three packages reach the web bundle only through the fork's own `mermaid` edge — `khroma` via mermaid, `fastdom` and `strictdom` via cytoscape under it — so upstream's config has never carried overrides for them. Fixed with three `packageOverrides` entries: `khroma` needed a `license: "MIT"` declaration only, since it ships its own `license` file, and `fastdom` and `strictdom` needed a `generatedNotice` each, since both declare MIT and ship no notice file. Verified with the build itself — all three now appear in `apps/web/dist/third-party-licenses.json` with a license and a notice, and the workflow is green. The delta is held by the `mermaid-diagrams` inventory entry plus a `third-party-licenses-config` path policy, and the reason it escaped `verify.mjs` — which has no build step at all — is now `docs/fork/gaps.md`, _Nothing builds the web app before a merge is pushed_. 🤖 Generated with [Claude Code](https://claude.com/claude-code)

Long text below a scroll view could be collected by SnapShot but missing from the attachment details and the agent prompt. The structured tree silently cut names at 1,000 characters and values at 8,000, then took priority over the fuller plain text read.
This marks clipped text fields as truncated and reuses the existing plain text fallback when the structured tree is incomplete and the fallback recovers text. Complete trees keep their element bounds and state. A truncated tree also stays when plain text contains the same text, preserving useful metadata. If the plain text read fails, the partial tree remains available and is marked truncated.
Platform findings
The pinned xa11y Mac, Windows, and Linux readers enumerate children without filtering them by screen visibility. The loss fixed here happens after collection in T3's shared reader.
Verification
Limits
The existing 32,000-character and three-second limits remain. A plain text fallback has no per-element coordinates. This preserves text the app exposes; it cannot recover content absent from the app's accessibility tree, such as unloaded items in a virtualized list. Existing saved snapshots are unchanged.
Implemented with GPT-6 in the native Codex harness.
