Problem

Reviewers had to mark each changed file as viewed individually, making it slow to update review progress across a group of files.

Change

Shift-clicking a file’s Viewed checkbox now applies its viewed state to the range between it and the last clicked file, in displayed order. This also supports marking a range unviewed and keeps file folding consistent. The shared web and desktop PR panel use this behavior.

Scope and approval

This is a focused improvement to the existing PR file viewed controls. It adds range selection without changing the review workflow.

Verification

The focused range logic tests pass (6 tests total), as do lint and the web package typecheck. check:changed could not complete because the worktree’s .env has a symlink loop. Browser verification was not run.

🟠 High pullRequest/PullRequestCodeTab.tsx:708

Shift-clicking a range of more than 500 files queues every path, so the flush sends a setFilesViewed request that exceeds PullRequestSetFilesViewedInput’s 500-file limit; the viewed marks are not persisted even though the handler folds the files. Split queued paths into batches of at most 500 in filesViewedStore.ts, including paths queued by earlier presses.

Approvability

Verdict: Would Approve

Macroscope's review found this PR approvable — Adds Shift-click to mark an inclusive range of PR files viewed or unviewed and update their folding. The reported oversized-range persistence failure remains subject to the separate blocking correctness gate.

Needs human approval because:

Merges upstream `pingdotgg/t3code` `fe219c4de1` (95 commits, base
`49a9e80e0b`) into the fork. Branched from `main`; no open merge PR to
stack on.

## Resolution

15 conflicts, each resolved by the verdict `preflight.mjs` printed for
it. The full record is in `docs/fork/upstream-merge-log.md`
(2026-10-29). The main points:

- **`LegacySidebar.tsx` deleted upstream** (pingdotgg#21039). The deletion is
taken. Its fork deltas (touch long-press, Add project gate) already live
in `Sidebar.tsx` / `SidebarThreadRow.tsx`. The file's paths are removed
from three inventory entries, and the helper only it used is dropped
from `Sidebar.logic.ts`.
- **Composer access mode.** Upstream's simpler composer (pingdotgg#25869) shows
the Access control in three places: the Permissions chip, the
compact-menu section, and the effort-menu section in
`ComposerControlsBar.tsx`. All three are gated on `FEATURES.accessMode`.
`ComposerControlsBar.tsx` is added to `chat-composer-gates`.
- **Sidebar.** Upstream's boring-sidebar project folders are combined
with the fork's browse/closed/subtask filter. Upstream moved the row's
meta line into a `metaLine` variable, and the fork's owner name and
parent/child task links now live inside it.
- **Settings.** The boring-sidebar Labs rows are client settings and are
not gated. Simlock hosts join the `serverBehaviorSettings` rows, and the
`simlock-hosts` search id is mapped to that flag. The new Fallback model
row is hidden together with the default model row
(`defaultModelSetting`).
- **`AGENTS.md`.** Upstream now has agents check user-visible changes in
a real client without asking first. The fork's version says the same,
still pointing at the fork's skills.
- `agentContextBudget.json` uses upstream's numbers, plus the fork's 108
bytes for `ProjectScript.port`. The value `46015` was measured by
running the budget test.
- `pnpm-lock.yaml` was re-derived from upstream's copy.

**Merge stats:** 595 files landed vs 593 in the upstream range (the gap
is explained in the tracker entry). Fork delta: 766 files, unchanged.

## Verification

`verify.mjs` was run in full. These checks pass: duplicate-adds,
tripwires, resolution-check, unsupported-methods, lockfile, fmt, lint,
typecheck, build. In the test step, `web` and `client-runtime` pass. The
same failures as the 2026-10-27 and 2026-10-28 merges remain, each
confirmed failing alone:
- `t3`: `RepositoryIdentityResolver`, `GitVcsDriver`,
`CodexChatGptAuth`, `CodexManagedRuntime` (the known `/tmp` sticky-bit
gap)
- `provider-opencode`: `OpenCodeServerLedger`

## Usable as-is
- Boring sidebar project folders, two-line folder rows, and hiding empty
projects (pingdotgg#21039, pingdotgg#26387, pingdotgg#26391, pingdotgg#26463)
- Simpler composer with grouped controls and effort words (pingdotgg#25869). The
access-mode parts stay gated.
- Pending approvals on their timeline row (pingdotgg#26255); tool call diffs open
in the diff panel (pingdotgg#26304); compaction row timer (3ef1610)
- Many web fixes: chat tables, inline code double-click, numbered
composer lists, image chips, scroll-to-end, tool groups after a
usage-limit pause, long-thread timeline perf (pingdotgg#26727)
- New Claude threads default to Opus 5.5 (pingdotgg#26358)
- PR files: mark viewed with shift-click, and the diff follows the file
tree (pingdotgg#26349, pingdotgg#26730). These are reachable only where the PR surface is
(`pullRequestSurface`).

## Unsupported in Moatless / needs implementation
- **GitHub sign-in through the T3 Code for GitHub app** (pingdotgg#26245):
`sourceControl.signInStart`, `signInWait`, `signInCancel`, `appAccess`.
New `UnsupportedMethodError` entries.
- **Simlock device pools** (pingdotgg#25259, pingdotgg#26706): `device.simlockIdentity`
(new union entry) and the `simlockDeviceHostsEnabled` server setting.
Part of the device hub gap.
- **Fallback model when the default provider is out of usage** (pingdotgg#26164):
the `fallbackModelSelection` server setting cannot be saved, because
`server.updateSettings` is refused. The row is hidden.
- Managing GitHub maintainer edits (pingdotgg#25588): in the pull-request write
family Moatless does not dispatch.
- T3 Connect tunnel usage and T3 Chat account push (pingdotgg#26369, pingdotgg#25931):
relay/cloud, decided out.
- Mobile dynamic workflows in the Agents sheet (pingdotgg#18642) and the mobile
app fixes: mobile against Moatless is unverified.

## Backend behavior to consider reproducing in Moatless
These are listed under _Runtime fixes upstream made to its own server_
in `docs/fork/gaps.md`:
- Falling back to another provider when the default is out of usage
(pingdotgg#26164), and refreshing usage when a turn hits its limit (pingdotgg#26234); no
replay of stale Codex usage limits (pingdotgg#26331)
- Settling a thread at once when its watched PR merges (pingdotgg#26395).
Moatless reads no PR for settlement today, so this is a decision rather
than a fix.
- Loading long thread history in bounded pages (pingdotgg#26240); publishing
local git status before the remote lookup (pingdotgg#21046); releasing completed
PR sweep data (pingdotgg#25177)
- Thread links that outside MCP clients can open (pingdotgg#26642); listing
snoozed threads across projects in one MCP call (pingdotgg#26442)
- Provider approval and subagent fixes: Claude command approvals
(pingdotgg#20145), ACP ID-only approvals (pingdotgg#26647), Cursor subagents (pingdotgg#26592),
OpenCode subagent runtime mode (pingdotgg#26302), Codex shadow-home locks
(c4606e5); shorter remote reconnect and command delays (pingdotgg#25754)

## After merging
- Disable the new upstream workflow: `gh workflow disable
mobile-fingerprint-label.yml --repo soaplabs/t3code`
