Snapshot previews in sent messages were squeezed into one column of the two-column attachment grid, clipping the image and its app labels.

Let snapshots span both columns so they keep the composer's existing 208 × 112 frame and details. Remove the old test assertion that required the squeezed layout. Regular image and video thumbnails keep their existing layout.

Includes the two-line release-check prerequisite from #11426 by @ipanasenko in a separate commit. It pins the already-locked expo-audio version so fresh lockfile resolution uses its patch. Release Smoke passes locally with this pin; the prerequisite will leave this PR diff when #11426 lands on main.

Verified with 55 focused tests, web typecheck, targeted lint and formatting, and a real browser check at 1200, 640, and 390 px widths. The browser check failed before the fix and passed after it. The test setup timeout was raised locally for slow module loading and restored before commit.

Before:
Before: sent snapshot is squeezed while the composer preview is full width

After:
After: sent snapshot matches the composer preview

Model: GPT-6. Harness: Codex.

Approvability

Verdict: Approved at 0123768

Macroscope's review found this PR approvable — This is a two-line, localized UI fix that makes snapshot previews occupy the full existing attachment grid while preserving their intended size; other attachment layouts remain unchanged. The accompanying test only removes an obsolete conflicting assertion.

The Release Smoke blocker is resolved at b908996. The branch includes the two-line dependency pin from #11426 by @ipanasenko in a separate commit, with original author credit. Release Smoke passed locally and in CI. All current checks are green or intentionally skipped. Macroscope approved the latest commit; CodeRabbit withdrew its static-markup test suggestion after reviewing the browser evidence and repository test guidance.

expo-audio 57.0.5 was published, so a fresh lockfile resolution of ~57.0.4
picks it up and pnpm fails with ERR_PNPM_UNUSED_PATCH for the 57.0.4 patch.
The release smoke script regenerates the lockfile from scratch, so it broke
on every PR. Pin the exact version like expo-sharing already does.

Assert the snapshot two-column class

The rendered snapshot test asserts the frame class but not col-span-2. Add expect(markup).toContain("col-span-2") so the test detects removal of the required layout class. This is a test-coverage gap, not a production layout defect.

@coderabbitai I checked the outside-diff suggestion for MessagesTimeline.test.tsx. The missing class assertion is real, but I am declining that test approach because this repository's verification guidance says: "Do not render components to static markup to assert props or attributes."

The regression was checked in the real client with Chromium: before the fix the sent image measured 99 px wide versus 206 px in the composer; after the fix both measured 206 × 110 inside their borders at viewport widths of 1200, 640, and 390 px. Image expansion and accessibility details passed as well. The PR includes before-and-after evidence.

A class-string assertion would test the implementation rather than the browser's grid sizing. No new function or API was added, so the generic docstring-coverage warning does not need a code change either.

Tip

For best results, initiate chat on the files or code changes.

@Bil0000 Thanks for the detailed verification.

The Chromium checks validate the required user-visible behavior. They cover the relevant desktop and narrow viewport widths. The Comment images also show that the sent snapshot now preserves the composer preview size.

The static-markup class assertion conflicts with the repository guidance and would test the CSS implementation instead of the layout result. I withdraw that outside-diff test suggestion.

The docstring coverage warning does not apply to this CSS-only change.

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_.
