* fix(remote-terminal): keep a reconnected pane's size after an SSH outage (P1-4) (#26625) * fix(remote-terminal): keep a reconnected pane's grid when its stale stream is reaped (P1-4) The host's width floor only handed ownership to viewers that had claimed since subscribing. A reconnecting desktop pane re-subscribes without claiming, so when the heartbeat later reaped the dead socket that owned the floor, the host reclaimed the PTY to its spawn size (120x40) and held the pane there. The owner's same-client replacement stream now inherits the floor, and a pane whose stream was reaped before it reconnected resumes ownership on re-register unless the host or another viewer claimed since. * fix(remote-terminal): host typing during an outage revokes the reaped owner's resume Host input reaches the PTY without a renderer viewport claim once the host has reclaimed its grid, so the orphaned-owner entitlement survived and a passive reconnect resized the host pane back to the remote grid. The host write path now clears that entitlement on driving input (query replies, focus reports and launch writes excluded). * test(pty): stub the runtime's host-input note in write-path handler tests --------- Co-authored-by: m4air <m4air@Mac.localdomain> * fix(remote): an oversized RPC reply fails that request instead of closing the host connection (#26624) Expanding a folder with ~80k entries on a managed SSH host produced a files.readDir reply over the 4 MiB encrypted-reply cap. The channel treated that as a transport fault and closed the whole control socket (1013), and the explorer rendered the failed folder as empty. - The WebSocket RPC transport now answers an over-cap reply with a reply_too_large error for that request id, so the channel never sees it. - files.readDir checks remote listings against the request's content budget and names the entry count. - The explorer shows a subfolder's read error on its expanded row. Finding: HH-2 (Phase 3.7 hostile-host). Co-authored-by: m4air <m4air@Mac.localdomain> * fix(ssh): let a slow host finish installing the pinned Node runtime (HH-3) (#26631) * fix(ssh): let a slow host finish installing the pinned Node runtime The POSIX promote (extract, hash, self-test and publish the ~110 MiB node binary) ran under the 30 s default exec timeout. On slow home storage it timed out, the remote work kept running, and the runtime store lock it held stayed until the 20-minute stale rule, so relay rung A queued behind it past its own deploy bound. Give both platforms the 300 s promote bound and have the host release the store lock itself when the promote exits, with owner-checked releases so a late release never removes a lock someone else took. (HH-3) * fix(ssh): let the host release the store lock after a slow under-lock re-hash The under-lock re-check of a sibling-published runtime hashed the ~110 MiB executable as its own command under the 30 s exec default and outside the host-side lock release. On slow storage it timed out, the client correctly kept the lock, and nothing on the host freed it until the 20-minute stale rule, so later installers ran out their deploy bound. Run the re-hash and the conditional promote as one host command wrapped in the host release, and give every full-runtime hash, including the initial probe, the slow-storage bound. (HH-3) * test(ssh): count the combined under-lock re-probe and promote as one host command --------- Co-authored-by: m4air <m4air@Mac.localdomain> * fix(ssh): shell startup output on stdout no longer breaks SSH connect (HH-1) (#26617) * fix(ssh): fence captured exec stdout so shell rc output cannot break connect sshd runs the user's login shell before Orca's /bin/sh wrapper, so any startup-file stdout (fish/tcsh/zsh/bash echo, or a bare terminal-title escape) was glued onto every captured answer. The home probe read "banner\n/home/u" and connect failed with "Remote home is not a valid path". execCommand now wraps wrapped POSIX commands in a per-call nonce fence and returns only the payload between the markers; the SSH folder browser gets the same fence. The fence is the existing WSL captured-login-shell fence, moved to src/shared/posix-stdout-fence.ts so both transports share it. Finding: HH-1 (phase 3.7 hostile-host). Refs #8324. * fix(ssh): fence the login-shell Node probe and fall back from a noisy SFTP handshake The login-shell 'command -v node' probe ran unwrapped, so output from sshd's shell and the nested login profile became the Node path. It now prints a one-line fence every login shell parses, inside that shell. An external sftp-server is started through the user's shell, so startup output corrupts the SFTP handshake. ssh2 reports that parse failure only before the session is ready, so SshConnection.sftp tags it, and relay install transfers treat it as SFTP unavailable and stream over exec stdin. Finding: HH-1 follow-up (phase 3.7 hostile-host). Refs #8324. * fix(ssh): keep the stdout fence marker out of the command text The runtime-store inventory lists processes with ps, which prints its own script, so a literal marker in the script was read as the fence and the store GC skipped every pass. printf now joins the marker from two halves. --------- Co-authored-by: m4air <m4air@Mac.localdomain> * fix(orcad): finish an abandoned update on connect, and refresh renderers after a main-side re-pair (P1-A, P1-C) (#26635) * fix(orcad): finish an update or rollback its client abandoned, and tell renderers about main-side re-pairs P1-A: a wake that finds the activation fence now runs crash recovery, which takes only a stale, previous-boot or exited-own fence. Recovery of an activation interrupted after the candidate launched resumes it: the candidate commits if it passes the readiness gate, else the activation is undone as before. P1-C: invalidating a still-linked environment's transport restarts its status owner, and a renderer that sees status under a newer pairing revision re-reads the catalog before applying it. * fix(orcad): a resumed update keeps the app version that started it Recovery that commits an abandoned candidate stamped no activeAppVersion, so an older desktop read the host as pre-tracking and downgraded it over state the newer build had migrated. The activate journal now records the initiating app version; recovery stamps it, and a journal too old to carry it is undone instead of committed. * test(runtime-env): answer nothing for the status restart a re-pair now triggers * fix(orcad): recovery leaves running an update server a too-old journal cannot commit A journal without candidateAppVersion was sent to undo, which stopped a healthy candidate that had already migrated state and then refused to restart the incumbent, leaving the host serving nothing. Refuse instead, keeping the fence and the candidate, until the operator accepts Restore. --------- Co-authored-by: m4air <m4air@Mac.localdomain> * fix(terminal): a remote recovery never splices stale history above the new screen (P2-5, P2-7) (#26647) * fix(terminal): a remote recovery never splices stale history above the new screen A pushed remote snapshot (overflow recovery, seq-gap resync, first attach) is sent because the client's stream broke, so the pane's own history ends before that image. Since #26319 a screen-only image kept that history, splicing a stale block directly above the final screen with a silent gap of up to ~270k lines (P2-5), and a first attach to an older host left silent holes (P2-7). - Host: the ACK-overflow recovery serializes up to 1000 history rows. - Client: the seq-gap resync asks for the same 1000 rows. - Client: a pushed snapshot always replaces the pane's scrollback; the keep-local-scrollback path is removed. A screen-only image from an older host now shows only its screen, which is lossy but never misleading. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * fix(terminal): a pushed image replaces the normal buffer over a live alt screen too Over a pane already on the alternate screen, an image that also ended on alt repainted only its alt frame and kept the pane's normal buffer, inferring the two had frozen together. Inside the gap the TUI can exit, the shell print and a second TUI start, so once that TUI exited the pane showed its stale history where the host had the missed output. A pushed image now always rebuilds the normal buffer and history from the host before entering alt itself. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * fix(terminal): bound recovery history by link slack and keep pre-TUI scrollback under screen-only images A recovery that carries history now goes out only when the stream's ACK window has drained; under a sustained flood recoveries stay screen-only and the owed history follows once the client catches up, so snapshot bytes no longer outgrow the client's intake. A pushed image without history (scrollbackRows absent or 0) over a live alt screen repaints only the alt frame again, so a reconnect to an older host no longer wipes the pane's pre-TUI scrollback. --------- Co-authored-by: m4air <m4air@Mac.localdomain> Co-authored-by: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * fix(source-control): Stage All stages every change when the listing hit the 1,000 cap (HH-4) (#26618) * fix(source-control): Stage All stages every change when the listing hit the 1,000 cap The status listing stops at 1,000 rows, but Stage All built its path list from those rows, so it staged 1,000 of 20,000 changes and the next commit was silently partial. When the listing is capped, Stage All (and the Changes header Stage all) now asks the host to stage the whole worktree via an optional scope on git.bulkStage; unresolved conflicts stay unstaged. Older hosts ignore the field and stage the listed paths. Fixes HH-4. * fix(source-control): whole-worktree Stage All needs a host receipt, skips shared links, and reaches mobile - Scoped stage sends no paths and requires a stagedScope receipt, so an older runtime or relay stages nothing and the client reports it instead of a silent partial stage. - Scoped 'all' skips Orca's shared symlinks (configured and really a link), matching the status listing. - The capped-listing banner offers Stage All, reachable when the visible prefix is entirely staged. - Mobile reads didHitLimit and uses the same scoped stage and receipt. * test(source-control): type the Stage All test stubs so lint and the mobile test typecheck pass * fix(source-control): match Shared Paths saved as ./name or name/ against git's spelling The Shared Paths setting keeps entries as typed, but git prints worktree paths without a leading ./ or trailing /. Stage All's conflict path compared the raw spelling to git's untracked list and staged the shared node_modules link, and an exclude pathspec ending in / made git refuse the add after tracked changes were already staged. Status listing had the same mismatch. getSafeRelativePath now returns git's spelling, so every caller gets it, including saved settings. --------- Co-authored-by: m4air <m4air@Mac.localdomain> * fix(ssh): redeploy a managed server another desktop stopped; forget one whose host is gone (P1-D, P1-E) (#26628) * fix(ssh): redeploy a server another desktop stopped; let a dead managed host be forgotten P1-D: a connect whose linked server the host reports as not activated (another desktop stopped it) now goes on to the update check, which redeploys it in place. P1-E: add Forget (managedServer.forget, orca environment forget, Settings row) that runs Stop's local unlink without contacting the host; the verdict stays unverifiable. * test(ssh): type the forget test's hoisted store without an assertion * fix(ssh): never downgrade a stopped host; redeploy it mid-session and retry after a failure A stop now keeps the stopped build's Orca version, so an older desktop's reconnect skips as host-newer instead of starting an older server on a store a newer build migrated. A stop recorded without that version is not guessed at. A stopped host retries the redeploy on each connect instead of the once-per-version failure suppression, and a runtime call that finds the server stopped mid-session redeploys it before the call. * fix(ssh): rebuild the managed forward after redeploying a stopped host A redeploy can bind a different port than the reused forward targets. * fix(ssh): keep stop journals readable by older desktops and recheck version policy under the fence - The stop journal's recordAfter is the core deactivated record older peers compute; the committed record keeps activeAppVersion (which released planners already honour) and rolledBackFrom, rebuilt from recordBefore on recovery. - Auto-update re-applies its version policy to the record read under the host fence, and a census counted against another incumbent is treated as unverifiable. * fix(ssh): file a dispatched stop where older desktops cannot commit it, so their recovery never drops the version guard * fix(ssh): refuse a fresh deploy of an older orcad onto a host a newer desktop stopped The unlinked deploy path never consulted the stopped record's activeAppVersion, so a desktop without a link to the host could activate its older build over state a newer build migrated. Both the auto-update planner and the fresh deploy now apply one downgrade rule under the fence. --------- Co-authored-by: m4air <m4air@Mac.localdomain> * fix(ssh): redeploy a managed server a pre-version Stop left; let a forced deploy run over a newer one (#26766) A stopped activation record without activeAppVersion is what every Stop on main writes, so refusing it stranded those hosts behind an unforceable policy refusal. Only a provably newer host is now refused; a forced fresh deploy runs this version anyway, and the refusal names both versions. Co-authored-by: m4air <m4air@m4airs-MacBook-Air.local> * fix(remote-terminal): no keystroke lost, duplicated or split across a silent outage (P1-1, P1-2, P1-3) (#26630) * fix(remote-terminal): no keystroke lost, duplicated or split across a silent outage Remote pane input was fire-and-forget: keys handed to a socket that had silently died were gone, keys still in the 8 ms debounce at detection were cleared, and held keys were discarded when the auto-recovery window ran out. - New negotiated `inputAck` capability: the client names an input session and sequences Input frames (existing frame header `seq`); the host records the last applied sequence per (PTY, session) across connections, writes each sequence once and acks it with new opcode InputAck (18), sent only to clients that advertised the capability. - The pane keeps sent-but-unacked input and replays it to the same terminal on reattach; the host dedupes. Old hosts keep current behavior. - Debounced and claim-queued input at detection is held, not cleared. - Held input survives the 'disconnected' phase; the hold coalesces keys so minutes of typing do not hit the per-entry cap. - Banner copy no longer claims a one-minute retry window. Fixes P1-1, P1-2, P1-3 (phase 3.7 network findings). * fix(remote-terminal): never replay into a restarted runtime; keep Ctrl+C and validating paste in order - Host publishes inputLedgerId with inputAck; the client drops unacknowledged input sent to a different ledger (runtime restart with the same PTY) instead of running it twice. - A replayed duplicate is acked only after the original write settles. - Accepted input (Ctrl+C, Escape, paste) rides the sequenced stream and resolves on the host ack. - Keys typed while held queue behind a paste still in size validation. * fix(remote-terminal): parse subscribed capabilities into a typed shape instead of Reflect.get * fix(remote-terminal): ack only applied input; withdraw writes their caller gave up on - Host ledger records each write's outcome: a refused write is rolled back and never acked, so the client's replay writes it; nothing queued behind it runs or is acked. A write that threw is acked as delivery-unknown, so the client reports it failed and never replays it. - Paste and file-drop timeouts abort their accepted write: a copy still held for an outage is withdrawn, and a journaled copy is left out of the replay. - A batch of sequenced input keeps one endpoint and ledger, so a send that retires the stream mid-batch no longer discards earlier unacked input. * fix(remote-terminal): host writes sequenced input strictly in order and asks the live stream to resend after a refusal - The ledger admits only the next sequence; a refusal or gap answers with an InputAck resend request instead of WriteUnavailable, so the pane keeps its journal and resends on the same stream (no remount, no carrier bookkeeping). - Sequenced input uses the provider's settled write; an unverifiable handoff is delivery-unknown, not refused. - Replays fill given-up slots with empty input so the host can continue; the client remounts only after every resend backoff is refused. - Typing batched ahead of a paste goes out as its own sequences, so cancelling the paste keeps it. * refactor(remote-terminal): deliver sequenced input with standard go-back-N Replace the hand-built "block on refusal" bookkeeping with go-back-N: - Host: per (PTY, input session) the ledger keeps only appliedSeq, the highest contiguous confirmed write. Frames run one at a time in arrival order: a duplicate is re-acked, the next sequence is written and acked on confirmed success, and a refusal or gap is answered with a resend request carrying appliedSeq. No blocked state; every stream is equal. A settlement that proves no byte left is a refusal; one that may have written advances as delivery-unknown and is never retried. - Client: one journal keeps unacked input in order and resends from appliedSeq + 1 on a resend request (with backoff), on a new stream, or when acks stall. Refusals never remount the pane. Withdrawn pastes, stale query replies and over-budget bytes resend as empty slots. - The recovery hold pauses (keeps the rest) when a release is cut short by another outage, and keeps delivering typing after an accepted write a sequenced stream withdrew or could not confirm. - Add a seeded model-based test that drives the real pane transport, multiplexer and journal against the real host dispatcher and ledger through 2,000 random fault schedules. * test(remote-terminal): cover the refusal remount on a stream without sequenced input A sequenced stream now resends refused input on the same stream instead of remounting, so the end-to-end remount check negotiates no inputAck, as an older peer does. * fix(remote-terminal): escalate persistent input refusals, drop input once recovery gives up, and never report a lost unknown ack as applied - The pane falls back to its remount path when the host keeps refusing input past the resend backoff ladder. - Held and journaled input is discarded when auto-recovery gives up, and input typed under the disconnected banner is not held. - The host ledger answers a duplicate for its own sequence and remembers delivery-unknown outcomes; the client settles a write as applied only from its own ack. - The input model now requires a write reported applied to have reached the PTY whole, and covers a refusal that never clears.

On a real host a 200 s outage lost 102 of 120 keystrokes, although the pane reattached the same terminal on its own seconds later. Input now stays held for the same handle and incarnation while the pane is disconnected, for up to 5 minutes after it gave up. Past that grace it is discarded, and typing into the dead pane is refused, so stale keys never run at an arbitrary later reconnect. The grace is a timestamp checked when input moves, so a latched pane stays free of timers.

Orca Mobile
React Native companion app for Orca. Monitor worktrees, view terminal output, and send commands from your phone.
Local development uses two processes:
- Orca desktop/Electron from the repo root. This hosts the mobile WebSocket RPC server on port
6768. - Expo Metro from
mobile/. This serves the React Native app on port8081.
Unless a command says otherwise, run mobile app commands from the mobile/ directory.
Prerequisites
- Node.js 24+
- pnpm
- Xcode and/or Android Studio tooling for simulator or device builds
- Expo Go on your phone, or a development client build when native modules are needed
- Phone and desktop on the same LAN when testing a physical phone
Start Desktop Orca
From the repository root:
pnpm install
pnpm dev
Confirm the mobile RPC server is listening:
lsof -nP -iTCP:6768 -sTCP:LISTEN
Restart pnpm dev after changing Electron main-process code. Metro hot reload only applies to the mobile JavaScript bundle.
Start The Mobile App
cd mobile
pnpm install
pnpm start
Scan the Expo QR code with your phone's camera on iOS, or Expo Go on Android.
For a native dev-client build:
pnpm exec expo run:android
pnpm exec expo run:ios
pnpm start --dev-client
Pair With Desktop Orca
- Open Orca desktop.
- Go to Settings > Mobile.
- Scan the pairing QR code from the mobile app.
- Confirm the mobile host endpoint is
ws://<desktop-ip>:6768.
For the Android emulator, use ws://10.0.2.2:6768. For a physical phone, use the desktop LAN IP, for example ws://192.168.0.179:6768.
If the phone has a stale host entry, remove it from the app and pair again.
Development Paths
Android Phone
- Install Expo Go from Google Play
- Run
pnpm start, scan QR with Expo Go - For native modules:
pnpm exec expo run:android - Run with
pnpm start --dev-client
iOS Simulator
- Install Xcode from the App Store
- Run
pnpm start --iosto open in iOS Simulator
Physical Phone Debugging
The phone can be inspected through the connected device tooling:
orca snapshot --json
orca click --element @e3 --json
orca fill --element @e1 --value "ls" --json
orca screenshot --json
Use snapshot first to find the current element refs, then click/fill those refs. After mobile file edits, Metro usually hot reloads automatically, but navigating out of and back into the session screen can be useful because it re-runs terminal.subscribe.
Terminal Streaming Repro Without A Phone
Use this when terminal output does not render on device and you need to split server streaming bugs from WebView/UI bugs:
cd mobile
ORCA_MOBILE_WS_URL=ws://127.0.0.1:6768 pnpm exec tsx scripts/test-subscribe.ts <deviceToken> <serverPublicKeyB64>
You can pass a worktree selector as the third argument:
pnpm exec tsx scripts/test-subscribe.ts <deviceToken> <serverPublicKeyB64> "id:<worktreeId>"
pnpm exec tsx scripts/test-subscribe.ts <deviceToken> <serverPublicKeyB64> "path:/absolute/worktree/path"
pnpm exec tsx scripts/test-subscribe.ts <deviceToken> <serverPublicKeyB64> "name:my-worktree"
The expected result includes:
streamSawMarker: true
readSawMarker: true
If this repro fails, debug the desktop runtime/PTY path before the mobile WebView. If it passes but the phone is blank, debug the session screen or TerminalWebView readiness/queueing path.
Terminal Color Repro Without A Phone
Use this when terminal colors disappear after switching tabs. Open a Claude Code terminal and at least one other terminal in the target worktree, then run:
cd mobile
ORCA_MOBILE_WS_URL=ws://127.0.0.1:6768 pnpm exec tsx scripts/repro-terminal-colors.ts \
<deviceToken> <serverPublicKeyB64> "id:<worktreeId>"
The script captures terminal.subscribe snapshots in an A → B → A sequence and writes raw snapshots to mobile/terminal-color-repro/. If the two A snapshots have different sgrColor counts, the desktop snapshot changed during the switch. If they match, the ANSI color data is still present and the bug is in mobile replay/rendering.
Validation
Run these checks before committing mobile terminal changes:
cd mobile
pnpm exec tsc --noEmit
pnpm run check:tests-typecheck
pnpm lint
cd ..
pnpm typecheck:node
tsc --noEmit reads tsconfig.json, which excludes test files so Metro never bundles them.
tsconfig.test.json puts them back, and pnpm run typecheck:tests shows their errors in full.
check:tests-typecheck is the gate over it: a ratchet against tests-typecheck-baseline.txt, the
127 test files that do not typecheck yet. It fails when a file that checks today stops checking,
and when a baseline entry starts checking (prune it with
node scripts/check-tests-typecheck-ratchet.mjs --prune). The list may only shrink.
The same gate censuses the program first: every *.test.ts(x) on disk must be in it, or named in
the script's TESTS_OUTSIDE_PROGRAM with a reason. Without that, a test excluded from
tsconfig.test.json — or a Foo.test.tsx shadowed by a Foo.test.ts beside it, which a wildcard
include drops for the higher-priority extension — would leave the ratchet silently.
Protocol Version Compatibility
Mobile and desktop talk over a versioned protocol. Because mobile updates lag desktop by 24-48h via the App Store, both sides exchange version numbers on status.get so a genuinely incompatible combo can hard-block instead of silently misbehaving.
Constants live in two files (Metro can't resolve outside mobile/):
src/shared/protocol-version.ts—DESKTOP_PROTOCOL_VERSION,MIN_COMPATIBLE_MOBILE_VERSIONmobile/src/transport/protocol-version.ts—MOBILE_PROTOCOL_VERSION,MIN_COMPATIBLE_DESKTOP_VERSION
Today all four are set so evaluateCompat always returns { kind: 'ok' } — nothing blocks. The wire format is in place to flip a switch when needed.
When to bump
Bump DESKTOP_PROTOCOL_VERSION (and the mobile mirror MOBILE_PROTOCOL_VERSION when relevant) for breaking changes:
- Removed RPC method or required parameter that mobile uses
- Changed meaning (units, nullability) of an existing field mobile reads
- Changed encryption, framing, or auth handshake
Do not bump for additive changes:
- New RPC methods
- New optional fields on existing methods
- New event types in
terminal.subscribe
Set MIN_COMPATIBLE_MOBILE_VERSION (kill-switch) when desktop ships a change that requires a minimum mobile version to function safely. Same for MIN_COMPATIBLE_DESKTOP_VERSION from the mobile side.
When a verdict is blocked, mobile/src/components/ProtocolBlockScreen.tsx renders a screen pointing the user at the update that clears it. When mobile is too old it opens the newest release if the installed app's update check knows one, otherwise the App Store (iOS) or GitHub Releases (Android). When desktop is too old it opens GitHub Releases.
To exercise the block screen locally: set MIN_COMPATIBLE_DESKTOP_VERSION = 999 in mobile/src/transport/protocol-version.ts, rebuild, pair to any desktop. Revert before merging.
Mock Server
Develop the mobile app without a running Orca desktop instance:
pnpm mock-server # starts mock WebSocket server on port 6768
Connect from the app using endpoint ws://localhost:6768 and token mock-device-token.
Environment variables
MOCK_NATIVE_CHAT=1— serve the native-chat scenario (one live agent tab, empty transcript, image upload) instead of the default terminal fixtures.MOCK_CHAT_AGENT=omp— withMOCK_NATIVE_CHAT=1, present an OMP tab and four decoded transcript messages, including a tool call and result, instead of the default Claude scenario. It deliberately omitstranscriptPathto exercise legacy-hook readability discovery; current OMP hooks may report a path.MOCK_SERVER_KEY_FILE— persist the server keypair across restarts so a paired device keeps its public-key pin. A missing or invalid file is re-keyed with a warning, which forces a re-pair.
Scenario control files
Read on every request, so behaviour can be flipped mid-session without a restart (a restart would re-key E2EE and force a re-pair). Write the mode into the file, or delete it for the default.
MOCK_SEND_MODE_FILE(defaultorca-mock-send-modein the system temporary directory) —accept(default) accepts the send,errorfails it withmobile_input_floor_unavailable, anything else reports the send as rejected.MOCK_TERMINAL_LIST_MODE_FILE(defaultorca-mock-terminal-list-modein the system temporary directory) —omitreturns an empty terminal list,otherreturns a list that omits the chat handle, anything else lists it.MOCK_TERMINAL_STREAM_MODE_FILE(defaultorca-mock-terminal-stream-modein the system temporary directory) —deadanswers a subscribe withsubscribedthenend(a gone PTY), which is what exercises the rearm bound and terminal prune; anything else streams normally.
Connecting to Real Orca
- Start Orca desktop with WebSocket transport enabled
- In Orca, go to Settings > Mobile and scan the QR code with this app
- The QR encodes the connection endpoint, device token, and TLS fingerprint
