A page a client bounds by bytes (maxBytes) now leaves out updates a newer update of the same call in the scan makes moot, and drops moot content from the rest. Each sealed segment of a live chat's log loses the content a later update of the same call in it supersedes, on a thread of its own; seq, deltas and each call's last content stay. Co-Authored-By: Claude Opus 5.5 * acpmux: supersede only within a prompt; fence the sealed rename Review findings on #27614: - A call id names a call within one prompt: a user_message or turn_started between two updates keeps both, in pages and on disk. A read cut at a prompt (a fork through a turn) sees every call as logged. - The copy goes in under the writers' lock a retention commit holds, and only over the very file it was read from (device, inode, length): a retention rewrite, a delete or a replacement is never overwritten. - A segment that changed stops the pass without moving the marker. - The copy is removed on any error, and a crash's copy by the next pass. Co-Authored-By: Claude Opus 5.5 * acpmux: keep this PR to the open page; sealed-segment compaction moves to a follow-up Review found that rewriting sealed segments changes what a fork or export pinned mid-prompt reads, so this PR now changes only pages read newest first with a byte bound. A page of some kinds still resets at every prompt. Co-Authored-By: Claude Opus 5.5 * acpmux: touch only output-only updates, and keep the oldest of each call a page reads Review: dropping any covered update changed the fold where an update carries more than output (input keys merge, subagent _meta, a diff a hidden call shows), and the start time a page takes from the first update it reads. Now only an update of status and text content is touched, and the oldest of each call a page reads stays until an older record of the call makes it moot. Co-Authored-By: Claude Opus 5.5 * acpmux: scope superseded calls by subagent owner, keep content:null, honour stubs Review: a native subagent numbers its calls apart from its chat; an explicit content null clears output; a record a page stubs carries no output. Each now supersedes nothing it should not.

The retry wrapped only the endpoint, so a socket or daemon handshake failing after the endpoint came back bypassed the reconnect; the attach client now asks the machine link (AgentSessionAttachClient.Reconnect) when any part of its connection fails, and tries once more.

The retry now wraps the shared connection in the caller's task; a quiet first try tells its loss only when no retry follows or the retry fails too.

Every child inherited it: - An exit test's child traps on purpose. With the variable set, it spawned the backtracer to symbolicate the whole test binary, and the parent sat in wait4 until the stuck-test watchdog ended the run (BlockingCheckTests .aCheckedFileManagerCallOnTheMainThreadTraps, #26809 run 40999753339 shard 6, exit 143). - A privileged tool writes "swift runtime: backtrace-on-crash is not supported for privileged executables." to stderr first. A test reading the child's stderr took that line for the answer: ChromiumRuntimeInstaller failed with unsafeEntry and then stalled 303 s (same run, shard 5), as the python bridges #27981 fixed one by one did. The test bundle's load-time constructor now unsets the variable. The Swift runtime read it when libswiftCore loaded, before the bundle, so the test process keeps its own backtracer and no child gets one.

The last 12 came from action.agentPane.continueAfterError (9e836df43650), which shipped in 9 of the 21 languages. Fill it and the seven older keys that made up the rest of the debt, so the check reports 0 errors: - ActionCatalog: action.agentPane.continueAfterError, action.palette.forkAgentConversation, action.palette.forkAgentConversationTo - PaneCreation: paneCreation.allCommands - Updater: updater.button.updateAvailable, updater.button.updateAvailableNamed - CmuxHome: home.plan.title, home.plan.activeCount (all 20 languages) Wording follows each table's neighbours (the Fork Conversation family, Continue In…, Update Available, detail.plan). State is "translated" where the key's other languages are, and "needs_review" in CmuxHome, as that table's other machine translations are.

<54008264+lawrencecchen@users.noreply.github.com> Date: Fri, 30 Oct 2026 03:46:46 -0700 Subject: [PATCH 12/53] ci(nightly): the remote-daemon build and attest jobs take the Linux runner set (#28209) #25935 (85628c020a3) moved build-nightly-remote-daemon and attest-nightly-remote-daemon off the Mac builder onto blacksmith-4vcpu-ubuntu-2404. That label is outside the trusted runner set of #27125 (9127e619f76, "Linux jobs take the runner set, not one small Blacksmith label"), so tests/test_nightly_trusted_routing.py test_every_linux_nightly_job_takes_a_runner_set_member is red on feat-cmux-next (20 failures, both jobs) and nightly-guards / release-notary is red on every feat PR. Both jobs now use the runner-set expression of the other Linux nightly jobs (16 vCPU when vars.LINUX_RUNNER names it, else 32). They stay off the Macs, which was the goal of #25935. tests/test_gh_budget_wait.py pinned the attest job to the 4 vCPU label; that one assertion conflicts with the trusted-routing rule, so it now checks that the job holds no Mac and takes the runner set. Its other assertions are unchanged.

A fake peer checks that only a peer listing personStop gets the field, and that a non-person's Stop never carries it.

This daemon now forwards the person's Stop with _meta.acpmux.personStop to a peer that lists the personStop feature, and a peer takes it only from a peer daemon's own link (PeerToken, held to the peer's rules, not via web or device) and runs the same person_stop as for its own person. An older peer gets the plain cancel. A client's own personStop field is dropped before the forward.

An ask that ended unanswered is the same card with Skipped, Stopped before an answer or Not answered in the answer's place. The todo list keeps its bordered card, spinner, dashed and check marks. QuestionCard and PlanList are memoized on their immutable inputs; a new test counts their commits while 200 tokens stream in the same turn. Gallery: answered looks (stacked shipped, inline, check), ended looks (card shipped, pill, rule), and a todo list looks entry (card shipped, borderless, count). Co-Authored-By: Claude Opus 5.5 Agent-Session: https://cmux.com/deeplink/agent?id=aid-92fa78a91e29868c5eaa * fix(agent-pane): answered card spacing from the design tokens Co-Authored-By: Claude Opus 5.5 Agent-Session: https://cmux.com/deeplink/agent?id=aid-92fa78a91e29868c5eaa * test(agent-pane): cards re-created per token, as the transcript does; lower the type-scale baseline Co-Authored-By: Claude Opus 5.5 Agent-Session: https://cmux.com/deeplink/agent?id=aid-92fa78a91e29868c5eaa * test(agent-pane): count the cards' own renders, not a re-created Profiler's commits Co-Authored-By: Claude Opus 5.5 Agent-Session: https://cmux.com/deeplink/agent?id=aid-92fa78a91e29868c5eaa * test(agent-pane): mark the module mock's promise as handled Co-Authored-By: Claude Opus 5.5 Agent-Session: https://cmux.com/deeplink/agent?id=aid-92fa78a91e29868c5eaa * fix(agent-pane): one reply handler per live ask, so the memoized question card skips pane updates Review (Astra) of 0dd7e865: App.tsx made replyToQuestion(permission) anew each render, so the pending card's memo never held. Co-Authored-By: Claude Opus 5.5 Agent-Session: https://cmux.com/deeplink/agent?id=aid-92fa78a91e29868c5eaa * test(agent-pane): mount the live ask's card wrapper in the render-count test The live question card's reply handler moves into PermissionQuestion, which App.tsx's PermissionAsk renders; the test mounts that wrapper with one permission across 200 tokens, so dropping its useMemo fails the test.

Leo, 2026-10-30: "that visibility into huge-blue guys was (and is?) pretty bad". The deputies relaunched with only area and role tags came back on the bare default harness, without their profile's autocompact cap. A session/new from the command line names a predecessor by --harness-from, a succeeds= tag, --report-to or its starter of the same name family, a NAME-N name, or an area= tag (one pass over the session index; no transcript read). A start with no -m or -p that lands on the default where the predecessor ran a named profile is refused; a start whose profile, launcher, model, effort or autocompact cap differs gets a one-line warning naming both and --harness-from. --harness-from copies the predecessor's profile, preset, model and effort.

browsing is per session The transcript reader listener captures on the scroller, an ancestor of the rail, so a stopPropagation on the list ran too late: an upward wheel over an overflowing rail released the transcript follow. The reader now skips a wheel over a rail list marked data-rail-scrolls (railWheel.ts). A rail that fits its prompts is no scroll container again (overflow hidden), so the wheel over it reaches the transcript. The browsing latch remembers its session, so a reused transcript showing another chat follows its reader. Co-Authored-By: Claude Opus 5.5 * Rail wheel test: wrap a line past the print width Co-Authored-By: Claude Opus 5.5 * Rail wheel: a jump landing correction goes on under a rail wheel settleScroll ends on any reader input captured on the window, which runs before the rail can stop the event, so a wheel over an overflowing rail cancelled a clicked tick landing mid-correction. It now skips a wheel the rail owns (railOwnsWheel), as the transcript reader does. Co-Authored-By: Claude Opus 5.5 * Scrollbar guard: the rail list may hide its own scrollbar The session rail spec keeps the overflowing rail list free of any visible scrollbar.

The backoffs between the four tries waited a fixed 60, 120 and 240 s (gh_budget_wait.sh --backoff), the limit still held at the last try, and the job failed with the tree unpublished, so the NEXT nightly kept promoting an older commit. gh_budget_wait.sh gets --backoff-probe TRY PROBE: the action hides the refused response, so it reads PROBE (a read of the attestations API with the same token) and, while GitHub refuses it for the rate limit (429, or 403 with x-ratelimit-remaining: 0, Retry-After or a message naming the limit), waits for the reset that refusal names (Retry-After, else x-ratelimit-reset, else the secondary-limit backoff) and reads again. The next try runs once GitHub answers. A probe answered at once (200, 404, a permission 403, a 5xx) waits as --backoff did. Every wait counts against the job's ledger; the publish passes now allow 50 minutes (was 15), inside their 75-minute timeout with the 15 minutes of work. The last try still must pass, so nothing ships without provenance, and a real attestation failure still fails the publish. Tests: test_gh_budget_wait.py drives --backoff-probe against a fake gh (the reset a refusal names, a limit that holds for three looks, Retry-After and 429, the secondary-limit schedule, a probe answered at once, the job total); test_cmux_tui_publish_retries.py checks the publish passes wire it. Both fail against the previous script and workflow.

Co-Authored-By: Claude Opus 5.5 * docs(composer-menus): New Tab placement only; the agent chat keeps its row Co-Authored-By: Claude Opus 5.5 * Gallery cover names the component; onboarding test matches the cloud row by prefix The New Cloud Machine row now carries its description, so its accessible name starts with the label rather than equalling it. A gallery cover names a component, so the hook cover goes. Co-Authored-By: Claude Opus 5.5 * New Tab headline play reads the computer pill above the box The computer pill moved from the quiet row to the strip above the box, beside the folder pill, so a project name of another width moves it sideways; the play now holds only its row and size. Co-Authored-By: Claude Opus 5.5 * Cloud pick wait ends on a failed start and on any chat change A refused resume or open now marks the machine failed instead of leaving it at its old stage, and a pick waiting on a machine that failed reads Couldn't start and stops waiting to move the chat. A chat change drops the wait for good, so a chat that returns to the same key (an empty New Tab id) never inherits another chat's pick. Co-Authored-By: Claude Opus 5.5 * Cloud pick wait ends for good when the account stops listing the machine Before, the stored pick survived a list without the machine, so the machine coming back with a ready peer could still move the chat.

stop words ignored; daemon tool ranks before its app_ twin * test: cmux mcp serve resolves current to the caller's pane in a session no app owns (red) * cmux mcp: current resolves from the daemon when no app owns the session, as the CLI does * tool-evals: stand-in app answers beside; tab-not-split and run-without-empty-shell cases * tool-evals: 20 cases mined from real transcripts; docs ranking test names the daemon tool first * cmux mcp: with no app, a terminal with no place goes beside the chat (daemon neighbor); decimal fields take numbers; tool-evals Edit/Write * cmux mcp code mode: short rules in instructions (fits the 2048-char cut), common-tool sheet and result shapes in cmux_exec; compact docs answers; did-you-mean on unknown tool * test: compact docs answers and did-you-mean for an unknown tool in a script * cmux mcp code mode: tool sheet names the arguments of rename, grouping, status and notification (tool-evals: three regressions back to pass); harness setup settles before the agent looks * tool-evals: round 1 results (Sonnet and Opus, code mode); model retry on a dropped gateway connection * cmux mcp: review fixes: no-app fallback only places terminals (open_url stays on the daemon); text says terminal takes no current; compact only cmux's own tools and keeps required args; decimal schema stays a string, whole floats taken; empty query lists families * cmux docs: a tool's own name ranks first; caller terminal comes through the backend so the no-app open_url test fails without its guard; focus wording matches tab_focus * tool-evals: generic harness (OpenCode-like prompt, cmux tools listed directly) and an OpenRouter adapter, so any model runs * tool-evals: a failed session open stops its daemon (an overloaded panel leaked 1,115); OpenRouter fails fast on 4xx and a missing key * tool-evals: hybrid surface (cmux_exec plus the 21 common tools listed directly) * tool-evals: run on Linux (the rbx builder) without sandbox-exec * tool-evals: rbx panel scripts and cross-model comparison * cmux mcp code mode: tool calls return Promises (.catch works), a script written as one function runs, a missing selector and a timer name their fix, and the sheet runs commands in a shell tab that stays open (11-model panel) * tool-evals: real claude and codex CLIs as harnesses (claude-cli:, codex-cli:), each in a clean agent home with cmux MCP behind a logging relay * tool-evals: Claude through the Agent SDK and Codex through app-server (no TUI per run), each with a clean home and cmux MCP behind a logging relay * tool-evals: Claude Agent SDK runs the installed Claude Code (the bundled 2.1.81 got a 400 for Opus 5.5); an API Error result is an agent error * test(tool-evals): eval agents cannot open pages or reach the person's cmux (red) The sign-in-link-in-cmux case asks a model to open a link; models that ran `open https://example.com/device?code=ABCD-1234` opened it in the person's default browser (Helium) 11 times on 2026-10-28. The Claude Code and Codex samples run with no sandbox, and the shell sandbox allows /usr/bin/open. Moves the shell profile into live-guard.mjs unchanged and adds probes for open, osascript and the person's cmux app sockets in both profiles. * fix(tool-evals): eval agents run sandboxed off the person's browser and cmux app Claude Code and Codex samples now run under sandbox-exec with agentProfile, and the API runner's shell profile gets the same guards: /usr/bin/open and osascript cannot run, LaunchServices open is denied, and the person's cmux app sockets (~/.local/state/cmux, /tmp/cmux*.sock, $TMPDIR/cmux*/) are unreachable. A model that runs `open ` in sign-in-link-in-cmux now fails inside its sample instead of opening a Helium tab or a cmux tab. bun test tests/tool-evals/live-guard.test.mjs: 10/10 (3/10 before). * tool-evals: a sample waits while the Mac's PTYs are near the cap (the person's cmux shares it) * tool-evals: --remote-daemon runs each sample's daemon and MCP server on another host over ssh (this Mac's PTYs stay free); rbx panel takes a binary and drops gpt-oss-120b for GLM 5.3 Prime * tool-evals: agents run in a sandbox that hides this machine's skills and other samples' results (Codex read an old cmux skill and searched past results) * tool-evals: sign-in-link-in-cmux is an app-tier case (headless has no cmux browser); --tier selects * cmux mcp code mode: a script reads a change's new ids from the top of its answer too, and a terminal by its tab (head panel: 39 'needs terminal' errors across models) * cmux mcp: a terminal named by its tab resolves to that tab's terminal id (the daemon's current needs a pane, so the earlier shortcut failed its own test) * cmux mcp: review fixes: a tab names its terminal only where a terminal is required (terminal_list keeps its tab filter), in the tab's session and scope; a script that only starts like a function runs as written, and a wrapped one gets cmux * cmux mcp code mode: function-form scripts detected from the text alone (no eval probe, which could run script code), arrow forms wrapped again; tool-evals guard allows the resolved sample path (Codex could not read its home) * tool-evals: the remote MCP settings file is written and read back before the server starts (15 h4 samples got 'MCP server is off' and fell back to the shell) * cmux mcp code mode: a script that calls its own function returns that function's value; drop a test case that could not fail * cmux mcp code mode: a self-calling function script returns its value even when its body returns (the guard looked for 'return' anywhere) * tool-evals: the guard lets an agent list the directories above its own sample (Codex canonicalizes CODEX_HOME and stalled at start) * tool-evals: a sample that never reached the model (429, exhausted accounts, dropped stream) is retried; --rerun-errors runs again only an earlier run's agent/harness failures * cmux mcp code mode: the tool sheet names pane_neighbor_get (the pane on the person's right) and terminal_process_get (Opus looked for a layout tool); stand-in app focus names the tab * cmux mcp: a record a tool returned works where its id goes (models pass pane_neighbor_get's {pane: {id}} to tab_list); the sheet shows that answer's shape * cmux mcp code mode: the sheet says 'next to X' means a new tab in X's pane, and pane_split only when the person says split (6 of 9 OpenRouter models split the logs pane) * tool-evals: workspace order is graded by the sidebar's personal placement order (workspace_place {index} moves a workspace there; the session index stays) * tool-evals: round 2 results (12 models, real harnesses) * cmux mcp: a record becomes its id only where an id goes (a selector or a resource-id field); a json field keeps its object (review: keybindings_set args, settings_set value) --- cmux-tui/crates/cmux-tui/src/cli/mcp.rs | 79 ++- .../crates/cmux-tui/src/cli/mcp/code_mode.rs | 329 ++++++++-- .../crates/cmux-tui/src/cli/mcp/placement.rs | 81 ++- .../crates/cmux-tui/src/cli/mcp/schema.rs | 7 +- cmux-tui/crates/cmux-tui/src/cli/mcp/tests.rs | 207 ++++++- .../crates/cmux-tui/src/cli/mcp/v2_tools.rs | 58 ++ .../cmux-tui/tests/cli/caller_selector.rs | 72 +++ tests/agent-evals/snapshot.mjs | 4 + tests/tool-evals/README.md | 77 +++ tests/tool-evals/RESULTS.md | 87 +++ tests/tool-evals/agents-sdk.mjs | 214 +++++++ tests/tool-evals/cases/cli-grammar.ndjson | 7 + tests/tool-evals/cases/codemode.ndjson | 6 + tests/tool-evals/cases/controls.ndjson | 3 + tests/tool-evals/cases/discovery.ndjson | 4 + tests/tool-evals/cases/honesty.ndjson | 4 + tests/tool-evals/cases/placement.ndjson | 3 + tests/tool-evals/grade.mjs | 133 ++++ tests/tool-evals/live-guard.mjs | 54 ++ tests/tool-evals/live-guard.test.mjs | 89 +++ tests/tool-evals/mcp-log.mjs | 27 + tests/tool-evals/overlays/v1.json | 3 + tests/tool-evals/overlays/v3.json | 3 + tests/tool-evals/run.mjs | 586 ++++++++++++++++++ tests/tool-evals/scripts/compare.py | 34 + tests/tool-evals/scripts/panel-rbx.sh | 15 + tests/tool-evals/scripts/rbx-run.sh | 14 + tests/tool-evals/session.mjs | 302 +++++++++ tests/tool-evals/templates/app.json.gz | Bin 0 -> 80631 bytes tests/tool-evals/templates/claude.json.gz | Bin 0 -> 8524 bytes tests/tool-evals/trim-capture.mjs | 42 ++ 31 files changed, 2486 insertions(+), 58 deletions(-) create mode 100644 tests/tool-evals/README.md create mode 100644 tests/tool-evals/RESULTS.md create mode 100644 tests/tool-evals/agents-sdk.mjs create mode 100644 tests/tool-evals/cases/cli-grammar.ndjson create mode 100644 tests/tool-evals/cases/codemode.ndjson create mode 100644 tests/tool-evals/cases/controls.ndjson create mode 100644 tests/tool-evals/cases/discovery.ndjson create mode 100644 tests/tool-evals/cases/honesty.ndjson create mode 100644 tests/tool-evals/cases/placement.ndjson create mode 100644 tests/tool-evals/grade.mjs create mode 100644 tests/tool-evals/live-guard.mjs create mode 100644 tests/tool-evals/live-guard.test.mjs create mode 100644 tests/tool-evals/mcp-log.mjs create mode 100644 tests/tool-evals/overlays/v1.json create mode 100644 tests/tool-evals/overlays/v3.json create mode 100644 tests/tool-evals/run.mjs create mode 100755 tests/tool-evals/scripts/compare.py create mode 100755 tests/tool-evals/scripts/panel-rbx.sh create mode 100755 tests/tool-evals/scripts/rbx-run.sh create mode 100644 tests/tool-evals/session.mjs create mode 100644 tests/tool-evals/templates/app.json.gz create mode 100644 tests/tool-evals/templates/claude.json.gz create mode 100644 tests/tool-evals/trim-capture.mjs diff --git a/cmux-tui/crates/cmux-tui/src/cli/mcp.rs b/cmux-tui/crates/cmux-tui/src/cli/mcp.rs index 5500e211cfa2..1e8ec7f68c0d 100644 --- a/cmux-tui/crates/cmux-tui/src/cli/mcp.rs +++ b/cmux-tui/crates/cmux-tui/src/cli/mcp.rs @@ -187,6 +187,11 @@ pub(super) trait Backend { fn focus(&self) -> Result, CallFailure> { Ok(None) } + /// The terminal this server's client runs in (`CMUX_TUI_TERMINAL_ID`), + /// for placing it without an app (placement.rs `daemon_caller`). + fn caller_terminal(&self) -> Option { + std::env::var("CMUX_TUI_TERMINAL_ID").ok().filter(|id| !id.is_empty()) + } /// Holds the session daemon's `session.events` stream open until /// `deadline` and calls `on_wake` with each item (the initial snapshot /// first, or with `cursor` the journal batches after it), and with @@ -874,6 +879,62 @@ impl Server { Ok(self.call_action(tool, &arguments)) } + /// A terminal tool called with a `tab` and no `terminal`: the terminal that tab shows, + /// from `tab_get` (its `content_id`).

The help is now grouped (machines, run and connect, files, snapshots, ports, network, chats, account), opens with a quick start (list, new, exec, pause, resume, kill), gives each verb one line in English and Japanese, and marks the verbs that need --confirm. `cmux cloud --help` prints that verb's usage and description and names `cmux action describe` for the full argument list. `cmux help cloud` now follows the locale too. The verbs live in one table (cli/cloud_help.rs) whose rows are rendered in one column; a test fails when it differs from the catalog's offered cloud verbs, and the cloud exec parse error reuses the table's usage line. Co-Authored-By: Claude Opus 5.5 Agent-Session: https://cmux.com/deeplink/agent?id=aid-fb75b7af9902231028aa * fix(cli): cloud help flags match the catalog; say which verbs take no target Review findings: new-machine gains --repo, --bootstrap and --bootstrap-script, open-desktop --viewer, deliver-secrets --names; apply-machine-config loses a --repo it does not take. The intro says an action on one machine needs --target, since new-machine, start-session --name and move do not. A test now pins which verbs take no target.

From 00e8c4a87d77b7e9bd79818c36208bdeba9c0a1e Mon Sep 17 00:00:00 2001 From: Leo Date: Fri, 30 Oct 2026 04:39:41 -0700 Subject: [PATCH 34/53] fix(ios): make recovery screens retry their failed loads (#27309) * fix(ios): retry failed loads from recovery screens Wire the shared recovery control to the workspace loader, terminal owner, stream opener, Feed refresh, Home refresh and conversation loader. Add behavioral loader tests and persistent demo capture states. Fleet compile and execution pending; this lane VM has no Swift compiler.

Now everything after the handshake goes out together (status, the list, the attach and its permission and handoff reads), and acpmux names the turn's opener in the attach reply (`turnOpener`), so the first frame waits on the handshake plus one round trip. An older acpmux leaves `turnOpener` out and the pane reads it as before. Co-Authored-By: Claude Opus 5.5 * acpmux: rustfmt the turn opener Co-Authored-By: Claude Opus 5.5 * cmux-next: hold a dropped early attach's live records until the chat attaches again Co-Authored-By: Claude Opus 5.5 * cmux-next: an early attach whose reply is of another session starts the chat over Co-Authored-By: Claude Opus 5.5 * cmux-next: name the early attach's held records apart from copyLive's Co-Authored-By: Claude Opus 5.5 * cmux-next: an early attach whose row changed after it streamed attaches again Records the attach asked with the chat list streamed before the row changed may be of the session before (recreated meanwhile), so the open attaches again. A dropped early attach's held records are discarded by the next attach, whose page holds them, instead of applied: some may be of another session. Co-Authored-By: Claude Opus 5.5 * cmux-next: the new-tab tail tests wait for the tail read the early attach goes out before The attach now goes out with the chat list, so a held attach is asked before the host tail is read and drawn; the tests let that read land before they look. Co-Authored-By: Claude Opus 5.5 * cmux-next: no retry for an early attach whose row only changed status An ordinary record is followed by its row change, so marking an early attach suspect on any row change after a record retried normal streaming opens. The cases it was for are peer chats, whose dropped early attach's records the next attach now discards; a row that names another session is still caught by the watch (strayedFrom) and the reply checks. Co-Authored-By: Claude Opus 5.5 * cmux-next: the peer-copy daemon scripts the attach asked of the listed chat The pane now asks its chat's attach with the chat list, before it knows the chat runs on another machine, and drops that attach for a peer chat. The stand-in daemon answered its once-only hooks (records during the attach, a recreation, refusals) on that first attach; it now answers an attach asked before the list as the machine is, and scripts the one the open asks of the chat as listed. Co-Authored-By: Claude Opus 5.5 * cmux-next: the peer-copy daemon tells an attach asked before the list by the list's answer The pane sends the list and the early attach in one go, so the list is asked before that attach; what marks it is that the list was not answered yet. Co-Authored-By: Claude Opus 5.5 * cmux-next: a dropped early attach's refusal is handled; peer tests count the listed attaches Co-Authored-By: Claude Opus 5.5 * cmux-next: the peer-copy daemon answers an early attach of its local chat as before Co-Authored-By: Claude Opus 5.5 * cmux-next: a dropped early attach is detached once it is in, not before acpmux runs each request on its own task, so a detach sent while the attach was still out could run first and leave its subscription behind.

The tile now holds its hover controls and lights only its more button; the profile control, whose pill is the control, keeps the selected step. A group header's open editor painted the hover step over the whole bar and did not light its trigger. The more button now stays lit while the editor is open and the bar keeps its own fill. No position, size or slot changes.

From 0a088aa224772245c7102a55d5b2f638491c68ae Mon Sep 17 00:00:00 2001 From: Leo Date: Fri, 30 Oct 2026 04:54:57 -0700 Subject: [PATCH 39/53] acpmux + agent pane: Stop always ends the turn stopped with Continue; held agent messages say a Stop holds them (#28154) * test(acpmux): a Stop always ends its turn stopped; a Stop's hold shows on held cards (red) Red at this commit: - stop_settles_tests: a Stop while the agent starts, or during a failover, is refused with "session has no live agent"; a Stop the agent answers end_turn ends the turn completed. - stopHeldMessages.test.tsx: the pane never reads a Stop's queue_paused. Co-Authored-By: Claude Opus 5.5 Agent-Session: https://cmux.com/deeplink/agent?id=aid-68aba5b97ce5dc80805d * fix(acpmux): a Stop always ends its turn stopped; held agent messages say a Stop holds them Leo, 2026-10-29: "i literally can't stop you i clicked the stop button and it didnt do anything so this is still busted didnt we say we were going to fix this in acpmux?" and "this is so awkward the stop button doesnt really work and resume doesnt really appear!?" Daemon (hub/cancel.rs, hub/turns.rs): - A Stop while the chat has no agent (it starts, or a failover's fallback does) is taken: the turn reads stopping, its prompt never reaches the agent that comes, and the turn ends cancelled. It used to be refused with "session has no live agent", and a failover's fallback then ran the prompt. - A turn a Stop kept from its agent ends cancelled, not failed. - A turn a Stop was stopping ends cancelled whatever stop reason its agent gives (an adapter that answers the cancel end_turn read as completed). Either way clients offer Continue on it. Pane: other agents' messages a person's Stop holds (queue_paused with reason stop) say so over the first card, and what lets them in, instead of "Read after this turn"; a resume or acpmux's list lets them go. Green: cargo test -p acpmux --lib stop_settles_tests (3 pass, red at the previous commit); bun test src/agent-session/acpmux/stopHeldMessages.test.tsx (2 pass, red at the previous commit).

Test: a Stop its agent answers with an error still ends the turn cancelled. - P2: acpmux's queue list names the messages a person's Stop holds (heldByStop), so a pane that attaches with none of the Stop's records still says they're held. Protocol IR and web types regenerated. - P2: an edit, a reorder or a sender recheck keeps a message's Stop hold. Co-Authored-By: Claude Opus 5.5 Agent-Session: https://cmux.com/deeplink/agent?id=aid-68aba5b97ce5dc80805d * fix(acpmux): a Stop's hold survives a failed start, a requeue and a release; Send now and edits clear it Review fixes (Sol BLOCK at f9a80d74bee1, five P2s), each with a test that fails without its fix: - A start that failed after an accepted Stop ended the turn failed; it now ends cancelled (fail_unstarted_turn). - Agent messages that joined a stopped turn came back unheld and ran right after the Stop; requeue_joined now keeps the Stop's hold and logs queue_paused with reason "stop". - resume_held named prompts a Stop still holds in queue_resumed; it now names only those it let go. - The pane kept "Held" on a message the person edited or sent now. Red at f9a80d74bee1: stop_settles_tests' three new tests fail (no mux queue_paused record; promptIds named p-agent; status failed), and stopHeldMessages' fourth test fails. Green: stop_settles_tests 7 pass (3 runs), hub_integration stop/held_queue/failover/inbox_digest/... 116 pass, 2 fail the same way on base (this host's TMPDIR). Co-Authored-By: Claude Opus 5.5 Agent-Session: https://cmux.com/deeplink/agent?id=aid-68aba5b97ce5dc80805d * fix(acpmux): a Stop's record names the agent messages a failed turn held already Review fix (Sol BLOCK at 88bfb9ac1850, P2): a person's Stop holds every other agent's queued message, but hold_agent_messages named in its queue_paused (reason "stop") only those it newly held. One a failed turn held already was left out, so an attached pane kept "Read after this turn" on it while acpmux's list said heldByStop. The record now names them all; their state is unchanged. Red at 88bfb9ac1850: an_automatic_release_names_only_the_prompts_it_let_go fails with "no mux queue_paused record". Green: acpmux lib stop_settles_tests/turns_copy_stop_tests/cancel/digest/queue 110 pass; hub_integration stop::/held_queue/inbox_digest/agent_digest/auto_resume 88 pass, 1 fails the same way on base (this host's TMPDIR).

The roster saves its cursor only when an agent event arrives, so a quiet stretch leaves it behind the head: 9,821 records behind on the nightly registry, and every start decodes 13 sealed segments to fold records that change nothing. a_maintenance_tick_saves_the_roster_cursor_at_the_journal_head: after non-agent journal records, a catch-up saves the cursor at the head. catch_up_agent_roster is a no-op stub.

Every start then decoded the 13 sealed segments between (gzip JSON, about 300 ms cold) to fold records that change nothing. - advance_agent_roster: the live fold's loop (registry -> roster locks, the non-output tail read, the snapshot save on the connection alone), folding through a sequence or the journal head. - catch_up_agent_roster folds to the head and saves; the journal maintenance worker runs it every tick (30 s), so a start replays at most one tick of records. A plugin delta it meets first is applied there, since the live fold then finds that record behind the cursor. Shutdown does not call it: it takes the registry lock, which a commit stuck in admission can hold (shutdown_returns_when_an_admitted_commit_stays_blocked). Clone of the 41.6 GB registry, same Mac, release build, cold page cache, 6 runs each: restore.snapshot 634-648 ms (real state, cursor 9,821 behind) -> 369-395 ms (state after a 45 s run with this build, cursor moved to the head by its first maintenance tick). The old build on that caught-up state gives 372-413 ms, so the saving is the replayed tail alone. sidebar.get p50 about 5 ms either way.

Two tests still assumed the old placement and timing: - thread-minimap-narrow: the file runs with Reduce Motion on, so the strip's revealed rail hides at once instead of after HOVER_INTENT.cardGrace. The grace case now turns motion on, and a new case covers the immediate hide under Reduce Motion. - transcript-follow: the touch tap at the pane's left edge (x + 12) now lands on a rail tick, which jumps to that prompt and unmounts the streaming row. The tap now lands on a reply's text, checked to be off the rail. Agent-Session: https://cmux.com/deeplink/agent?id=aid-fb75b7af9902231028aa Co-Authored-By: Claude Opus 5.5 * fix(webviews): scale the tool output viewport cap with transcript text size #26696 capped every [data-output-viewport] at a fixed calc(8 * 18px + 16px). At larger chat text sizes that box holds fewer than eight lines, and transcript-content-font fails ("eight scaled lines remain in the preview", 160 < 288 at 28px). The cap is now eight 18/14-scaled lines plus padding, which is still 160px at the 14px default. Not 8lh: the Markdown viewport sets no line-height of its own, so its lh would be the inherited normal line-height and the Markdown preview would shrink below its base height (Codex review of #28135).

Co-Authored-By: Claude Opus 5.5 Agent-Session: https://cmux.com/deeplink/agent?id=aid-e4bb2734e4f1e2182e74 * cmux-next iOS: the slash-command list scrolls inside the room above the composer Typing "/" listed every command in a plain stack of fixed 44 pt rows, and the chat's dock measures its stack at its ideal height and proposes none, so twenty commands asked for 880 pt and ran past the screen. The transcript now publishes the stack's ceiling (under the header, inside the dock's host); the list takes the room between that ceiling, less what the stack shows over the composer, and the composer card, and scrolls the rest. Every command stays; rows are at least 44 pt and grow with Dynamic Type. The @ mention list is unchanged.

A false Clear ends the work under it. Both now read the same identity as servers do: exact argv, and the executable the kernel says runs must be the file argv[0] names. The launcher is read from the leader's exact argv too, so one whose path has a space in it relays; the ps leader line (tree::leader_args_in) is gone.

Identity now carries the folder the process runs in (/proc//cwd, proc_pidinfo PROC_PIDVNODEPATHINFO), and a relative script must be the server's file from there. A folder that can't be read is no match. - A launcher run as a bare `node` trusted any executable named node. It must now be the one the harness's PATH runs (what `#!/usr/bin/env node` execs); with no PATH known (a harness another daemon started) a bare name is no launcher. The census gets the PATH with the servers. The process-scan baseline row for tree.rs goes from 5 to 7 (the two folder reads), still class remove with the census.

The relayed program's real file must now be under the outermost node_modules folder that holds the launcher script's real file (npm puts the package's native program there, nested or hoisted); a script outside node_modules relays nothing.
