Summary

  • Keep Cloud terminal sidebar and tab provider icons sourced from the authoritative projected Cloud resource.
  • Reconcile full snapshots, live deltas, removals, completion/kill, and reopen transitions without cross-terminal icon leakage.
  • Preserve generic terminal fallback and local terminal behavior.

Testing

  • Existing focused suites in this branch: CloudNameAuthorityTests, CloudSidebarConsistencyTests, TerminalTabIconRegressionTests.
  • Covered Cloud icon persistence across local title updates, local fallback, provider identity, and projection reconciliation.
  • Hosted CI remains the required Swift/macOS validation; no prohibited local xcodebuild or VM fleet commands were run.

Issues

Impact map

  • Source of truth: SurfaceCatalog Cloud resource projection and SurfaceResource.terminalAgentIconAssetName.
  • Direct callers: Cloud sidebar rows, Cloud tab projection/icon synchronization, snapshot and live delta application, terminal reopen/restore paths.
  • Cross-surface effects: Cloud-only icons update from latest agent/provider identity; local tabs retain generic terminal fallback; stale snapshots and unrelated terminal deltas are scoped out.
  • Tests and evidence: focused Cloud name/sidebar/tab regression suites plus hosted CI.
  • Residual risk: end-to-end fleet runtime evidence requires HQ Mac controller submission on this exact head.

Mergeability

  • Head SHA: 07bf306
  • Base: main
  • Conflict-only gate: pending fresh server check

📝 Walkthrough

Walkthrough

The changes add durable publication and snapshot support for terminal titles, a daemon-managed agent screen-detection plugin, expanded hook-provider coverage, and an OpenCode provider fallback. Cloud terminal icon resolution now uses the projected agent icon. Detection and journal handling also change how agent state and process exits are applied.

Changes

Durable terminal titles

Layer / File(s) Summary
Capture and present runtime titles
cmux-tui/crates/cmux-tui-core/src/surface.rs, cmux-tui/crates/cmux-tui-core/src/surface/directory.rs
Runtime state tracks reported and published titles separately. Local and hosted title reports schedule publication, while replayed titles use separate handling.
Persist titles and project snapshots
cmux-tui/crates/cmux-tui-core/src/workspace_registry/resource_store.rs, cmux-tui/crates/cmux-tui-core/src/workspace_registry.rs, cmux-tui/crates/cmux-tui-core/src/workspace_registry/session_journal.rs, cmux-tui/crates/cmux-tui-core/src/resource_api.rs, cmux-tui/crates/cmux-tui-core/src/mux/resource_content.rs, cmux-tui/crates/cmux-tui-core/src/mux/terminal_directory.rs, cmux-tui/spec/resource-api-v2.md
The registry stores terminal titles and provides title readers. Terminal snapshots include persisted titles, and title changes are journal subjects. The specification describes title precedence and publication behavior.
Throttle and commit title updates
cmux-tui/crates/cmux-tui-core/src/mux.rs, cmux-tui/crates/cmux-tui-core/src/mux/terminal_title.rs, cmux-tui/crates/cmux-tui-core/src/resource_api.rs
A mux-bound publisher coalesces reports, commits resource patches, and flushes pending titles at shutdown. Tests cover throttling and persisted-title behavior.

Agent screen detection and hooks

Layer / File(s) Summary
Build and publish pinned plugin artifacts
.github/workflows/cmux-tui-artifacts.yml
The workflow builds, verifies, attests, and publishes plugin artifacts with commit-addressed and rolling manifests.
Resolve and install plugin sources
web/services/vms/drivers/cmuxTuiDaemon.ts, web/tests/vm-cmux-tui.test.ts
The driver resolves a plugin manifest matching the daemon commit, installs and configures the plugin, and checks its pin and runtime readiness. Hook-provider coverage includes Claude, Codex, OpenCode, and pi. Tests cover source resolution, configuration, installation, and readiness.
Bake and validate plugin-enabled images
web/scripts/build-devbox-freestyle.ts, web/scripts/verify-devbox-image.ts, web/scripts/devbox-image-common.ts, web/scripts/probe-busybox-cmux-tui.ts, web/tests/freestyle-cloud-shell-repair.test.ts, web/tests/vm-devbox-image.test.ts, web/tests/vm-image-manifest.test.ts, docs/cloud-cmux-tui-daemon.md, web/services/vms/images/manifest.json
Image builds record the plugin pin and verify its running state. Manifest validation checks paired plugin metadata. The image list changes its default records and adds plugin-pinned images. Documentation describes plugin installation and readiness.
Preserve agent-reported idle state
cmux-tui/bindings/examples/rust-agent-screen-detection/src/manifest.rs, cmux-tui/bindings/examples/rust-agent-screen-detection/src/scanner.rs, cmux-tui/bindings/examples/rust-agent-screen-detection/src/detect.rs
Detections identify rules based on OSC title or progress. Output activity no longer upgrades an idle state reported by the agent.
End matching hook-owned roster rows
cmux-tui/crates/cmux-tui-core/src/journal_reducers.rs
A matching plugin process-exit event can remove the agent’s hook-owned roster row.

OpenCode plane fallback

Layer / File(s) Summary
Build plane provider configuration
web/services/coderouter/opencodeProxy.ts, web/tests/coderouter-opencode-proxy.test.ts
When no usable OpenCode Go account exists, configuration can use eligible Responses and Claude accounts. Tests cover provider selection, model lists, credentials, and lookup errors.
Handle definitive configuration responses
web/services/vms/images/devbox/agent-config.sh, web/tests/vm-devbox-image.test.ts
The image initialization script distinguishes non-retryable HTTP responses and can start OpenCode without cmux configuration. Tests cover definitive responses and later configuration retrieval.

Cloud terminal agent icon

Layer / File(s) Summary
Resolve icons from Cloud terminal state
Sources/TerminalTabAgentIcon.swift, cmuxTests/CloudNameAuthorityTests.swift
The method returns the projected Cloud terminal agent icon and no longer resolves local PID or restored-agent state. Tests cover Cloud and local icon behavior after a title update.

Merge Risk: 🟡 Moderate · up to 407e7

The new default devbox images record the agent plugin pin, and the manifest update itself looks consistent. Three issues raised earlier are still open:

  • Very long terminal titles can show different values in snapshots and in stored events.
  • An unrelated agent's exit can clear a valid agent status row.
  • Each title update does work that grows with the number of terminals and tabs.

These should be addressed or explicitly accepted before merging.

Full details: Docstring Coverage

Explanation

Docstring coverage is 60.95% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 105 functions across 27 files. (1 skipped: 1 unsupported.)

Full details: Cmux No Hacky Sleeps

Explanation

The diff introduces a production polling delay in cmuxAgentPluginReadyCommand (web/services/vms/drivers/cmuxTuiDaemon.ts). The generated shell command checks the daemon child and journal producer, then runs sleep 1 on each failed attempt for up to 30 attempts. Build and image-verification scripts execute this command, so this is not test-only scaffolding. The delay masks asynchronous plugin startup and producer registration instead of using an owner-provided readiness event. The focused test also locks in the generated bounded polling loop.

Resolution

Remove the for ... sleep 1 readiness polling from cmuxAgentPluginReadyCommand. Add an explicit readiness signal owned by the daemon or plugin, such as a journal producer-registration completion/status operation or a supervisor-provided readiness file/event, and make the bake and image verifier wait for that signal with a bounded, cancellation-aware operation. Test the success, failure, and cancellation paths without asserting a fixed sleep.

Full details: Cmux Algorithmic Complexity

Explanation

The new runtime title publisher adds repeated scalable scans in cmux-tui/crates/cmux-tui-core/src/mux/terminal_title.rs. At line 61, every title-report wake scans last_published with retain; with about 1000 active terminals, many reports in one interval create repeated O(T) work. At lines 233-240, each published title snapshots all topology rows, scans every tab for one terminal, and sorts that terminal's tabs. This runs on the resource/socket publication path once per terminal publication. Across many terminals, it becomes repeated O(T * tabs) work, with additional O(k log k) sorting. The helper use is new in this PR; the existing helper was not used by the title publisher in the base revision. No benchmark or explicit lower bound justifies this shape.

Resolution

Use an expiry queue or min-heap, or lazy per-terminal expiry, instead of retaining the entire last_published map on every report. Maintain a terminal-to-tab index or obtain the already ordered tab IDs from the existing topology/state index. Build the terminal snapshot from that index without scanning topology.tabs and sorting for each title event. Add a benchmark or measurement for roughly 1000 terminals/tabs if a full scan remains necessary.

Full details: Cmux User-Facing Error Privacy

Explanation

The PR adds a user-visible privacy violation on the Cloud OpenCode launch path. The API now returns "The team has no coderouter account OpenCode can use (OpenCode Go, Codex, OpenAI, OpenRouter, Anthropic API key, or Bedrock). Add one with \cr add`."inweb/services/coderouter/opencodeProxy.ts. The baked agent-config.shwrapper forwards that APImessageto stderr, and itsopencode()function runs this wrapper before launching OpenCode. A cmux user therefore sees upstream vendor names, internal provider details, and an internal CLI recovery command. The base version returned onlyno_usable_account`, while this PR makes the response non-retryable and prints its message.

Resolution

Use provider-neutral recovery text in the API response, such as “No model account is available for this team. Add a model account in cmux, then retry.” Do not include OpenCode Go, Codex, OpenAI, OpenRouter, Anthropic, Bedrock, provider-specific flags, or internal commands. Also stop the guest wrapper from forwarding arbitrary API message values; map the non-retryable error to a fixed sanitized message before printing it.

Full details: Cmux Full Internationalization

Explanation

The Cloud OpenCode production path adds English user-facing copy without a locale source. In web/services/coderouter/opencodeProxy.ts, planeFallbackConfig returns apiError messages at lines 551 and 564; apiError serializes message into the JSON API response. The new messages are coderouter could not load the team's accounts. Retry shortly. and The team has no coderouter account OpenCode can use (...). Add one with \cr add`.. The devbox wrapper then prints the server message to the user at web/services/vms/images/devbox/agent-config.sh:202,247. No web/messages/or locale files changed.web/i18n/routing.ts` lists 20 locales, and the 20 corresponding message files contain no entries for this copy.

Resolution

Use a locale-specific source for the new API copy and pass the request locale through the OpenCode configuration flow, then add matching translated entries to every file in web/messages/ for all 20 locales. Alternatively, return only stable machine error codes from this API and render localized text in the user-facing client. Update the devbox wrapper so it does not print an untranslated server message, or localize its own fallback text through the same supported-locale mechanism.

Resolution

Add the required Changelog, Demo Video, and Checklist sections. State the exact test commands that ran, their results, and any remaining verification limits. Complete each applicable checklist item, including localization, documentation, review, and any relevant soak or relay checks.

🟡 Minor · Use public_terminal_snapshot for catalog-only terminals. · resource_content.rs:1009

cmux-tui/crates/cmux-tui-core/src/mux/resource_content.rs:1009
🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Use public_terminal_snapshot for catalog-only terminals.

A terminal with no tab can remain in state.terminal_catalog. This branch then emits surface.title() directly. After host reattachment, that value can be empty while public_terminal_snapshot correctly falls back to the persisted title. Build this value with public_terminal_snapshot and pass the stored title.

Preserve deferred terminal-title reports during shutdown.

stop_terminal_title_publisher() drains pending reports and ignores the publication result. publish_terminal_title() can return Deferred, or fail before committing the title. Shutdown then prevents the worker from requeueing the report, so the final title can be lost. Handle deferred and failed publications before shutdown returns.

stop_terminal_title_publisher and its shutdown flow to preserve drained reports

title. Handle those outcomes before shutdown prevents the worker from requeueing
the reports, so the final title is not lost.

Use an indexed per-content tab lookup for title publication.

publish_terminal_title holds both the registry and state locks while resource_topology_snapshot() reads the global topology and the code scans every live tab to select one terminal's tabs. The one-second throttle applies per terminal, so N changing terminals still perform O(N×T) total tab-scan work per second, where T is the number of live tabs. This can delay other operations that need state.

Add a registry query for live tabs by content_id, backed by resource_tabs_by_content, and preserve the existing canonical ordering. Keep the registry-to-state fence valid while building and committing the title patch.

Normalize reported titles before presenting them.

If a hosted surface starts with an over-limit term.title(), its constructor stores that value directly in reported_title and title. surface.presented_title returns the raw reported value, while the publisher truncates the title before persisting and emitting its delta. A snapshot and its corresponding delta can therefore disagree.

Apply the title limit at the shared presentation boundary. Bounding only record_reported_title and record_replayed_title does not cover the hosted initialization path.

Queue the initial hosted replay title for publication.

spawn_hosted seeds reported_title from the replay, but it does not schedule publication. The scheduling calls only cover later output, resize, reconnect, and test paths. An idle hosted terminal can therefore show the replay title in live snapshots without committing the title upsert. Schedule the seeded report after terminal registration and activation.

Normalize the region before setting agent_reported.

validate_region_name accepts surrounding whitespace, and region() trims the value before reading OSC metadata. This comparison uses the raw value, so " osc_title " matches OSC data but sets agent_reported to false. The scanner can then let output activity upgrade that agent-reported idle to working.

Suggested fix
-            agent_reported: matches!(rule.region.as_str(), "osc_title" | "osc_progress"),
+            agent_reported: matches!(rule.region.trim(), "osc_title" | "osc_progress"),

macos / macOS compile admission: /tmp/cmux-ci/src/Sources/TerminalController+SharedSizing.swift:313:52: error: value of type 'BonsplitController' has no member 'popoverAnchorView'

Not re-run automatically: guards / workflow-guard-submodule-forward-only, macos / macOS compile admission are not machine failures.

Written by scripts/ci/classify_failures.py (ci-failure-attribution.yml); signatures are its SIGNATURES table. A machine verdict is the runner's fault, not this PR's.

Dogfood tours of b0a6934e

sidebar-and-chrome-tour at b0a6934e: not run

skipped: CI left no app build for this head (its compile failed or was cancelled)

Tours are picked by the paths globs in dogfood/scenarios/*.json; a Dogfood-tours: a, b line in the description picks them instead (none turns this off). Look at every frame before merging: a green tour only means no step failed.
