An environment whose server speaks a newer wire protocol was drawn like a failed connection: red dot, red text, and on web a large "Client not supported" button. Nothing is wrong with the machine, this build just cannot talk to it.

Unsupported rows now keep the neutral dot and muted subtitle with the controls disabled as before. The full compatibility sentence (which side to update) moves into the tooltip. On web the "not added" row shows a disabled Add button instead of the label-as-button.

The relay health probe already returns the server descriptor, including the detected machine kind, so discovered and saved-but-unreached rows now wear that glyph instead of the generic server icon. resolveEnvironmentMachineKind accepts a bare descriptor; the user's icon override still wins once settings arrive. Servers that predate machine detection still show the generic icon.

Surfaces: web settings Environments list, web T3 Connect discovery list (plain and onboarding checkbox variant), mobile Environments sheet, mobile onboarding sheet, mobile bearer rows. Desktop wraps web. The mobile full-screen "Client not supported" notice and the update-launch popover mapping are unchanged, since unsupported is still blocking there.

Before / after

Screenshots use fixture relay data (two machines reporting a newer protocol, one compatible).

Verification

  • vp test run on packages/contracts/src/server.test.ts (new bare-descriptor case), cloudEnvironmentConnectionPresentation.test.ts (unsupported now idle tone), CloudEnvironmentConnectList.test.tsx, mobile cloudEnvironmentPresentation.test.ts, client-runtime presentation.test.ts.
  • Typecheck for contracts, web, mobile; lint on touched files.

📝 Walkthrough

Walkthrough

The change uses relay descriptors to resolve machine kinds before connection when saved configuration is absent. Mobile and web surfaces now render machine icons consistently. Unsupported environments use muted status, explanatory tooltips, and disabled Add actions when unsaved.

Changes

Unsupported environment presentation

Layer / File(s) Summary
Machine kind resolution contract
packages/contracts/src/server.ts, packages/contracts/src/server.test.ts
resolveEnvironmentMachineKind accepts minimal environment metadata and falls back from configured icon to detected platform to server.
Web connection presentation and controls
apps/web/src/components/cloud/*, apps/web/src/components/settings/ConnectionsSettings.tsx, apps/web/src/components/ConnectionStatusDot.tsx
Web rows resolve machine icons from relay descriptors. Unsupported environments use muted status, detail tooltips, and disabled Add controls when unsaved.
Mobile connection presentation
apps/mobile/src/features/connection/*
Mobile rows resolve machine kinds from saved configuration or relay descriptors. Unsupported states no longer use failure styling.

Approvability

Verdict: Approved at bf57791

Macroscope's review found this PR approvable — This is a focused presentation bug fix that neutralizes unsupported connection rows and derives machine icons from existing relay metadata without changing connection workflows or persisted schemas. Saved icon overrides remain authoritative, and targeted tests cover the new resolver and presentation behavior.

Merges `pingdotgg/t3code` `6d1d549441` into the fork, from base
`0bf2d6b010` — 50 commits.

- **Landed:** 410 files against 407 in the upstream range; the gap of 3
is `docs/fork/gaps.md`, `inventory.json` and `upstream-merge-log.md`.
Everything in the range landed.
- **Fork delta:** 777 files.
- **Verification:** all 9 `verify.mjs` checks pass, tests green in all
15 packages.
- **Unsupported methods:** ADD 0, DROP 0 —
`packages/contracts/src/rpc.ts` and `auth.ts` are untouched. Upstream
added no WebSocket method in this range.

## The one that mattered

Upstream's pingdotgg#12015 moved the **entire body of the thread route** out of
`apps/web/src/routes/_chat.$environmentId.$threadId.tsx` and into a new
upstream file, `apps/web/src/components/ThreadRouteView.tsx`, rendered
by the `_chat` layout so a draft's promotion keeps the same `ChatView`
mounted. The route file is now a seven-line stub.

Three fork deltas lived in that file. They moved with it:
`useAdoptedThread`, `useAutoFollowThread` and the
`serverThreadAwaitingFirstAnswer` argument to
`resolveThreadRouteRenderState`, all reading `target.kind === "server" ?
target.threadRef : null` — a draft's reserved ref is the viewer's own
work and the listing carries it without being asked. The
`unlisted-thread-adoption` and `thread-follow` inventory entries were
re-pointed at the new file.

The fork's own delta guard is what caught this. The merge was clean and
typecheck was green; `features.test.ts` failed because
`useAutoFollowThread` was no longer in a file the inventory said it had
to be in.

## Conflicts

8 files, each resolved with the verdict `preflight.mjs` printed. Details
in the tracker entry; the short form:

| file | verdict | resolution |
| --- | --- | --- |
| `routes/_chat.$environmentId.$threadId.tsx` | unlisted | took
upstream's stub, deltas relocated (above) |
| `chat/MessagesTimeline.tsx` | `message-origin-upstream-files` | both
sides of `TimelineRowActivityState`, its memo and its deps merged;
dropped upstream's now-unused `GitPullRequestIcon` |
| `ThreadStatusIndicators.tsx` | `thread-status-indicators` | fork's
memo above upstream's early return — hooks before any conditional
`return null` |
| `settings/ProviderInstanceCard.tsx` | unlisted, in
`moatless-provider-auth` | kept the `FEATURES.providerConfiguration`
ternary, took upstream's container-query classNames inside it |
| `settings/SettingsPanels.tsx` | `settings-surface-gates` | re-stated
the fork's browser clause onto upstream's rewritten `proactive-panels`
text |
| `BranchToolbar.tsx` | `branch-toolbar-gates` | import block, both
sides kept |
| `RightPanelTabs.tsx` | `right-panel-surfaces` | import block, both
sides kept |
| `pnpm-lock.yaml` | `theirs — lockfile` | `--theirs` then `vp i`,
re-derived lockfile committed |

## Path policy closed a hole

`resolution-check` listed eight unlisted paths both sides changed;
**seven carried a real fork delta**, so next merge's `theirs` fallback
would have dropped them silently. All seven are now listed — five new
entries (`command-palette-gates`, `diff-panel-gates`,
`provider-settings-gates`, `chat-layout-route`,
`client-runtime-exports`) plus `rightPanelStore.test.ts` added to
`right-panel-surfaces`. The eighth is the thread route stub, which
resolved to upstream byte for byte.

## Usable as-is

Client work that runs against the Moatless backend today:

- **pingdotgg#12015** worktree setup card no longer flashes or shifts (the
relocation above) · **pingdotgg#12144** thread reading positions are preserved ·
**pingdotgg#12162** header spacing stays stable when the sidebar drawer opens
- **pingdotgg#8641** timestamps on tool rows and turn folds · **pingdotgg#12152** those
timestamps sit before the disclosure chevron · **pingdotgg#12147** thoughts group
into the changing tool activity line
- **pingdotgg#12075** send-shortcut and follow-up controls · **pingdotgg#12160** rich text
composer on by default · **pingdotgg#12165** composer task rows aligned ·
**pingdotgg#11787** tooltips on the composer's environment and workspace controls
· **pingdotgg#12082** simpler agent approval prompts
- **pingdotgg#12139** diff panel defaults to the working tree · **pingdotgg#12190** diff
files collapse by default · **pingdotgg#12142** a linked pull request wins over
an automatic diff
- **pingdotgg#12143** themes picked from chat with colour previews · **pingdotgg#12138**
provider settings adapt to content width · **pingdotgg#12167** follow-up and
license controls aligned
- **pingdotgg#12026** unsupported environments render as neutral rows with their
machine icon · **pingdotgg#12030** a discovered machine's icon survives a relay
refresh · **pingdotgg#12001** dropped folders become path chips locally and are
refused on remote environments
- **pingdotgg#11144** pull-request icon state centralised — a refactor the fork's
own badge filtering now rides

Not fork surfaces, landed for completeness: the mobile work (pingdotgg#11841,
pingdotgg#12169, pingdotgg#12177, version bump), the CLI installer progress bar (pingdotgg#12044),
docs (pingdotgg#11696), release chores and the Fable 5.1 badge (pingdotgg#12173).

## Unsupported in Moatless / needs implementation

- **Pull request surface** — `FEATURES.pullRequestSurface` is off, so
none of this merge's pull-request work is reachable: **pingdotgg#11994** (submit
PR comments with Cmd/Ctrl+Enter), **pingdotgg#12150** (comments easier to scan,
`apps/web/src/components/pullRequest/**` plus a `pullRequest.ts`
contract field), **pingdotgg#12168** (cached GitHub PR details reused across
entry points), **pingdotgg#12125** and **pingdotgg#11728** (author avatars and their
fallback). **pingdotgg#11706** needs backend work on top: private-repository
media in PR tabs goes through a new `packages/contracts/src/assets.ts`
proxy that Moatless would have to serve. Opening the surface means
deleting the `pullRequestSurface` entry and its gates, and dispatching
`pullRequests.list` / `.detail` / `.activity` — only
`pullRequests.summary` is served today.
- **Keybindings settings page** — **pingdotgg#12175** turns every keybinding
command into a searchable settings row pointing at
`/settings/keybindings`, which `FEATURES.serverAdministration` keeps out
of the sidebar and redirects on a typed URL. The rows still match in
settings search and land on that redirect. Left as-is this merge — it is
the same shape as the six `snap-shot-*` rows that have always done this,
and the one-line fix (a `settingsPathEnabled(item.to)` filter in
`filterAvailableSettingsSearchItems`) is a behaviour change that belongs
outside a merge. Recorded in `gaps.md`. Closes properly when
`server.upsertKeybinding` / `removeKeybinding` are dispatched.
- **Device hub** — **pingdotgg#12017** (detect unsupported legacy Android
command-line tools) and **pingdotgg#12033** (resolve Node for standalone helper
scripts) are both `apps/server/src/device/**`. `FEATURES.deviceHub` is
off and Moatless runs no device host at all, so there is nothing to do
and nothing to reproduce.

## Backend behavior to consider reproducing in Moatless

All recorded in `docs/fork/gaps.md`; nothing in this repository holds
them open.

Checkpoint and turn path, under _Runtime fixes upstream made to its own
server_:

- **pingdotgg#12154** keep large sparse checkouts on the fast checkpoint path —
streams `git ls-files --full-name --sparse -z -v` under a 4 KiB cap and
pins `sparse.expectFilesOutsideOfPatterns=false`. Without it a sparse
checkout large enough to blow the output limit drops to the slow path on
every checkpoint.
- **pingdotgg#10944** flush checkpoint objects and refs before publishing them —
otherwise a reader that acts on the announcement can find a ref pointing
at an object that is not there yet. Rare, unreproducible, permanent when
it lands.
- **pingdotgg#8432** keep a ready checkpoint when a later placeholder arrives
(`ProjectionPipeline.ts`) — the symptom is a checkpoint reverting to
pending and never coming back.
- **pingdotgg#11970** keep VCS waits from blocking turn completion
(`ProviderRuntimeIngestion.ts`, `decider.ts`) — a slow git call between
the provider's last event and the turn being marked done. Slower in a
sandbox than upstream.

Settlement, under _Settlement rules Moatless owns_:

- **pingdotgg#12161** settle on the `thread.pull-request-linked` / `-synced`
event with a per-thread sweep rather than waiting for the next periodic
one.
- **pingdotgg#12176** make the cancellation path uninterruptible around
record-and-rollback, so a cancelled worktree setup records its
settlement instead of being left mid-setup.

Client features that are inert until the backend emits or honours
something:

- **pingdotgg#11784** provider thinking traces — `orchestration` gained a
`reasoning` message role and `thread.message.reasoning.delta` /
`.complete` commands behind a `reasoningMessages: true` opt-in on
subscribe. The client renders them when they arrive; Moatless emits
none, so there are no traces.
- **pingdotgg#10822** complete counts and progressive large diffs —
`review.getDiffPreview` gained an optional `file` input (one file's
patch) and an optional `files` stat array ("absent on older servers").
Moatless dispatches the method and honours neither, so large diffs stay
truncated with incomplete counts.
- **pingdotgg#11519** native provider slash commands, exposed server-side and
consumed by the mobile client.
- **pingdotgg#12115** OpenCode Go, Cursor and Grok subscription limits in the
usage scan.

## Verification

`tripwires`, `duplicate-adds`, `resolution-check`, `inventory-check`,
`unsupported-methods`, `lockfile`, `fmt:check`, `lint` and `typecheck`
all pass; tests pass in all 15 packages. Two failures were found and
fixed on the way:

- `TS2552: Cannot find name 'label'` in `ThreadStatusIndicators.tsx` —
pingdotgg#11104/pingdotgg#11180 hoisted `label` onto the presentation object and the
fork's multi-link popover branch still read the removed local.
- The delta-guard test failure described above.

Two operational notes for the next run are in the tracker entry: `vp i`
needs `NODE_OPTIONS=--max-old-space-size=6144` in this sandbox, and
`--force-with-lease` needs the explicit `<ref>:<sha>` form with the SHA
read from `git ls-remote`, because this clone only fetches `main` and
the branch has no lease-eligible tracking ref.
