**Full Changelog**: pingdotgg/t3code@v0.0.39-nightly.20260907.1325...v0.0.39-nightly.20260907.1332

Upstream release: https://github.com/pingdotgg/t3code/releases/tag/v0.0.39-nightly.20260907.1332

Merges 141 upstream commits (`b438447f6..8b2838e`) into the fork,
following the
`fork-upstream-merge` skill. Landed as a merge commit; conflicts
resolved by the
path-policy verdicts in `docs/fork/inventory.json`.

## Merge shape

563 files landed (`git diff --stat HEAD^1 HEAD`) against 563 in the
upstream
range, so no upstream work was dropped. Fork delta 720 files.

## Conflicts

14 files, resolved by concern. The merge commit message names each. Two
are worth
carrying forward:

- Upstream extracted the project action rows into
`ProjectActionsList.tsx`. The
fork's Edit gate now rides an `editable` prop that defaults to
upstream's
  always-editable behavior, so the gate survives the next extraction.
- Upstream moved the `agent-browser-access` setting onto its new
`/settings/projects` page. `settingsSearch.ts` points that item there
and drops
  a fork delta.

## Two things a clean merge did not show

**Upstream can delete an export the fork still imports.** pingdotgg#10225 removed
`ClientTracingLive` as unused. `apps/web/src/lib/runtime.ts` still
installs it,
and neither file conflicted, so the typecheck failed four ways on a
merge git
called clean. Restored with a `// Fork:` comment naming the consumer.

**A green test step can hide a suite that never finished.** `vp run -r
test`
kills the packages still running when one of them fails. A
`@t3tools/desktop`
failure truncated `apps/web` and `@t3tools/mobile` after each had
reported
hundreds of passing files, and `verify.mjs` counted any package with
labeled
output as tested. Four failing web tests went unreported. The check now
keys on
the closing `Test Files` line and runs every unfinished package alone.

## Unsupported methods

`unsupported-methods.mjs` reports 0 ADD, 0 DROP, 2 KEEP, against 61
dispatched
backend methods and 131 contract methods.

Getting there took a fix. The backend moved its dispatch from
`crates/t3code/src/lib.rs` to `crates/t3code/src/rpc/dispatch.rs`, where
every
arm is a one-line call into a handler below the match. The script read
the old
path and reported zero dispatched methods, then read the new one and
called
`vcs.switchRef` a DROP, because the `unsupported_exit` that refuses it
had moved
out of the arm. It now tries both paths and follows an arm two calls
deep.

Contract changes: `provider.consumeResetCredit` and
`server.getHostResources`
gained `UnsupportedMethodError`; `server.getUsageSummary` lost it, which
closes
the item the previous merge left open.

## Feature classification

**Usable as-is** — client-only, nothing new on the wire. Sidebar drag
across
sections with destination cues and a named drop action (pingdotgg#9731, pingdotgg#9750,
pingdotgg#10378,
pingdotgg#10453, pingdotgg#10464). Composer behavior: a multiline draft survives timeline
scrolling (pingdotgg#10444), the composer stops collapsing on blur (pingdotgg#10437) and
regains
focus when you tab back (pingdotgg#10463). Panel and preview chrome: resize the
floating
preview from any edge (pingdotgg#10467), toolbar controls stay anchored (pingdotgg#10478),
the
stuck resize cursor clears (pingdotgg#10461), the browser hides as the right
panel closes
(pingdotgg#10385), manual panel choices hold during a turn (pingdotgg#10113). Settings and
accessibility polish (pingdotgg#10177, pingdotgg#10262, pingdotgg#10415, pingdotgg#10258, pingdotgg#10124, pingdotgg#10125,
pingdotgg#10127,
pingdotgg#10128, pingdotgg#10175). Performance (pingdotgg#10413, pingdotgg#10190, pingdotgg#10118). Plus the GitHub
mark on
`github.com` links (pingdotgg#10324), the Tux icon for WSL (pingdotgg#8511), a remembered
usage
page selection (pingdotgg#10189), project settings in the legacy sidebar menu
(pingdotgg#10021),
and text-only preview snapshots (pingdotgg#10232).

**Unsupported in Moatless** — resolves to a refusal, or falls through to
its own
empty state. Each is recorded in `docs/fork/gaps.md`:

- Reset credits through the hub and CLIProxyAPI (pingdotgg#10462, pingdotgg#10395,
pingdotgg#10308).
`provider.consumeResetCredit`, new union entry. `UsageLimits.tsx`
catches the
  refusal and shows "Could not use the reset credit."
- Balancing new threads across connected machines (pingdotgg#9895, pingdotgg#10433,
pingdotgg#10407).
`server.getHostResources`, new union entry. Nothing polls until a user
picks
automatic routing, and the composer then reads "Auto balance
unavailable."
- Onboarding: import grouped by repository (pingdotgg#10493), the shared
multi-computer
  wizard (pingdotgg#10465), agent install without Node or npm (pingdotgg#10402). All ride
  `agentSessions.scan` and `.import`, an existing gap.
- Shared project defaults and scoped overrides (pingdotgg#9754). The page reads,
and every
  write goes through `server.updateSettings`, which the backend does not
  dispatch.
- Two new `orchestration.dispatchCommand` types: `thread.active.reorder`
(pingdotgg#9729)
and `thread.user-input.dismiss` (pingdotgg#10431). Both are ordinary controls, a
sidebar
drag and a Dismiss button, and a dispatched command cannot be refused
per type.
That is the standing _A command cannot be refused_ gap, now 26 members
wide.

**Backend behavior to consider reproducing in Moatless** — upstream
server fixes
whose behavior the fork's client assumes:

- Invalid script IDs no longer crash threads (pingdotgg#10019). The fork ships
project
  scripts, so this one is worth reading first.
- Settlement: settle inactive threads without a PR lookup (pingdotgg#10103), skip
disabled
settlement lookups (pingdotgg#10424), settle threads with unanswered async
questions
  (pingdotgg#10400).
- Interrupted threads stay resumable after a restart (pingdotgg#10421).
- Completed requests stay closed across clients (pingdotgg#10123).
- Placeholder branches are followed after a checkout updates (pingdotgg#10441).
- A thread's PR links without an open client (pingdotgg#10101), and checkpoints
are
  captured before a PR status refresh (pingdotgg#10347).
- Adapters declare their own context compaction (pingdotgg#10112).
- Transcripts with oversized tool records import (pingdotgg#10430), and git
status scans
  are skipped while the index is locked (pingdotgg#9845).
- Usage limits pool per provider across accounts and environments
(pingdotgg#10300). The
client renders what `server.getUsageSummary` returns, so this shows
something
  only if the Moatless payload carries per-account limits.

Mobile, marketing, desktop, provider adapters and release tooling are
not this
fork's surface and are not classified.

## Also fixed here, and not upstream's doing

- Three `browser-*` search items still routed to
`/settings/integrations`, which
the fork owns for its Moatless administration page. A non-administrator
who
  searched for them was redirected away from the result.
- `moatless/listSearch.ts` carried no fork-only declaration.
- `pnpm fmt:check` failed on 294 files, 293 of them orval output. The
generator
  now formats what it writes through an `afterAllFilesWrite` hook.
- `@t3tools/moatless-api` exported `./generated`, a barrel that is never
checked
  in.

## Verification

`inventory-check.mjs` clean. `verify.mjs` green on seven checks:
duplicate-adds,
tripwires, resolution-check, unsupported-methods, `fmt:check` (3876
files),
`lint` and `typecheck`.

`test` is red on one package, and it is the machine.
`@t3tools/desktop`'s
`bundled libsecret helper` shells out to `pkg-config` for `libsecret-1`,
which
this sandbox does not have; it fails the same way when retried alone.
Everything
else passes: `apps/web` 369 files, `t3` 291, `@t3tools/mobile` 149,
`t3code-relay` 27, `@t3tools/client-runtime` 71, plus the smaller
packages.

`spec:check` cannot run in a sandbox: it needs a sibling `moatless`
checkout or a
deployment URL and has neither.
