Cloud agent titles could change the visible terminal tab while the Cloud sidebar kept the old name. User renames then competed with local title callbacks and delayed daemon state.

This change routes Cloud terminal names through the exact machine/workspace/terminal/tab projection. The daemon persists name_source and name_revision; agent hooks capture that revision before computing a title, and stale callbacks cannot replace a newer name or an explicit user name. Layout tabs and sidebar rows consume the accepted graph. Workspace user names remain exact, including machine-like prefixes, through refresh and restore.

A user confirming an agent's existing text claims user ownership. Clearing a terminal name restores the process-title fallback. Automatic workspace naming targets the Cloud terminal placement rather than creating a local workspace alias.

Trade-offs:

  • Cloud UI names wait for daemon acknowledgement, avoiding an unconfirmed local value or rollback mismatch.
  • Automatic naming requires the new daemon metadata. Older daemons retain user rename support; automatic writes without a revision are refused to preserve existing user labels.
  • Verification uses isolated graph fixtures and hosted builds/tests. No live Cloud VM was changed and no dogfood build was launched.

Validation:

  • Separate test-only commits precede the implementation. Hosted Linux reproduced both automatic-over-user and stale-automatic failures: https://github.com/manaflow-ai/cmux/actions/runs/34743556176
  • Swift coverage exercises the production Codex socket path, shared Cmd+R rename owners, a decoy tab, similar names across workspaces/machines, stale snapshots, persistence/restore, clears, and layout/sidebar parity. Hosted validation is in progress; upstream compile integration errors are being repaired separately.
  • Swift file-length guard and localization catalog parity pass. Existing UI strings were retained and audited across all nine locales; neither Swift budget TSV is changed.
  • Structured code review returned no actionable defects; its file-organization finding was addressed. Final checks and review are in progress.

Fixes #12499.

📝 Walkthrough

Walkthrough

Changes

Cloud tab names now carry user or automatic ownership and revision metadata through the resource API, storage, snapshots, and rename commands. Swift cloud rename paths capture stable tab context, enforce guarded writes, synchronize local and sidebar titles, and pass context through agent naming hooks. Tests cover persistence, stale updates, identity checks, and layout/sidebar parity.

Cloud rename authority

Layer / File(s) Summary
Resource authority and persistence
cmux-tui/crates/cmux-tui-core/..., cmux-tui/spec/resource-operations-v2.json, cmux-tui/crates/cmux-tui/src/cli/command.rs
Tab snapshots and rename requests now include name ownership and revision fields. Automatic renames require matching generation and revision values. Registry migration and persistence retain the metadata.
Cloud name context and remote writes
Sources/Surfaces/CloudAgentNameContext.swift, Sources/Surfaces/SurfaceCatalog+NameAuthority.swift, Sources/Surfaces/CmuxTuiSurfaceProvider+AgentNaming.swift, Sources/Workspace+PanelTitleOwnership.swift
Cloud projections capture stable rename context. Panel and agent renames validate that context before submitting remote writes.
Title commands and reconciliation
Sources/TerminalController+AgentTitle.swift, CLI/CMUXCLI+AutoNaming*.swift, Sources/Surfaces/CloudWorkspaceRenameService+Reconciliation.swift, Sources/TabManager+WorkspaceCustomTitle.swift
Agent title commands and hooks pass cloud context through title application. Local and remote reconciliation use accepted authoritative names.
Validation and parity tests
cmuxTests/CloudNameAuthority*.swift, cmuxTests/SetAutoTitleSocketTests.swift, cmux-tui/crates/cmux-tui-core/src/**/tests.rs
Tests cover rejected unversioned or stale callbacks, persistence across restart, identity isolation, user/automatic precedence, and layout/sidebar parity.
Build and catalog synchronization
cmux.xcodeproj/project.pbxproj, cmux-tui/bindings/*/.cmux-resource-api.json
New Swift sources are added to the Xcode project, and binding manifests receive the updated resource catalog fingerprint.

Full details: Cmux Algorithmic Complexity

Explanation

The PR adds unindexed collection scans to the repeated auto-title socket path. SurfaceCatalog+NameAuthority.swift:51 filters the global SurfaceCatalog.projections set for each submitCloudWorkspaceRename call. The source == .user guard is after this lookup, so local or unbound automatic title events scan all projections and then return without a Cloud write. Workspace+PanelTitleOwnership.swift:20 also routes every automatic panel title through submitCloudPanelRename, whose SurfaceCatalog.swift:1254 accessor performs a linear projections.first scan. TerminalController+AgentTitle.swift:172-175 can invoke that path twice for a local panel: the explicit submission returns nil, then the fallback setter submits again. The collection is not bounded or indexed, and no measurement documents this repeated socket-path work. With about 1000 workspaces or projections, this causes O(P) global scanning per title event, twice in the local panel fallback case. This is a changed-code match for the rule's repeated filtering/scanning condition; the existing accessor alone would not fail, but the PR adds the hot callers.

Resolution

Maintain source-of-truth indexes in SurfaceCatalog, at minimum a panelID -> SurfaceProjection index and a workspaceID -> [SurfaceProjection] or equivalent grouped index, and update them whenever projections are recorded, moved, or ended. Use those indexes in submitCloudPanelRename and submitCloudWorkspaceRename instead of scanning the global projections set. Move the source/ownership decision ahead of the legacy fallback when it can return without resolution. In v2WorkspaceSetAutoTitle, pass propagateToCloud: false to the local fallback after an explicit submission returns nil, or return and reuse the first lookup result, so one socket event cannot repeat the same scan. Add a measurement for the roughly 1000-projection case if any linear fallback remains.

Full details: Cmux Swift Concurrency

Explanation

The diff introduces an unstructured fire-and-forget Task in Sources/Surfaces/SurfaceCatalog+NameAuthority.swift:80. observeCloudNameWrite starts it from synchronous rename APIs, awaits the remote rename, and presents failures, so it has a meaningful lifecycle. The task is not stored or cancelled, and its caller does not own an async operation. The existing CloudRenameCoordinator stores the separate write task, but it does not retain this observer task. No AppKit, SwiftUI, XCTest, OS, or third-party callback boundary requires this task.

Resolution

Use structured concurrency for the rename observation. Make the cloud rename submission path async throws and await the coordinator task from caller-owned async operations, with failure handling at the await site. If the synchronous UI APIs must remain, retain the observer task in a lifecycle-owned coordinator or SurfaceCatalog property, cancel it when the rename or owner is superseded or torn down, and remove it when it completes.

Full details: Cmux Swift Package Boundaries

Explanation

The pull request adds pure Cloud name-authority domain types to the app target without a SwiftPM boundary. Sources/Surfaces/CloudTabNameSource.swift, CloudTabNameAuthority.swift, and CloudVMTabState.swift are Foundation-only Codable/Sendable values. CloudTabNameAuthority parses the daemon extra.name_source and extra.name_revision contract. CloudAgentNameContext also performs JSON wire encoding and builds revision-fenced daemon arguments without AppKit, SwiftUI, Ghostty, or UI state. The Xcode project adds these files to the app target, and the diff adds no Swift package target. The feature owns a stable domain noun, a daemon data format, and cross-surface name state. The existing CmuxCore package already provides pure remote-domain models and an isolated test target. The app-specific SurfaceCatalog, Workspace, TerminalController, and provider code can remain composition glue.

Resolution

Use the existing CmuxCore SwiftPM target as the smallest extraction boundary. Move the dependency-free name-authority contract into that target, including CloudTabNameSource, CloudTabNameAuthority, the strict unsigned revision decoding needed by the contract, and a small precondition value for the tab identity, generation, and name revision. Expose public CloudTabNameAuthority as the first public type. Add focused CmuxCoreTests for metadata decoding, missing or invalid revisions, JSON round trips, and revision-fenced argument data. Keep SurfaceCatalog+NameAuthority, TerminalController+AgentTitle, Workspace+PanelTitleOwnership, and CmuxTuiSurfaceProvider+AgentNaming in the app target as adapters that construct the package values from app-owned graph state and perform lifecycle and UI updates.

Review follow-up at ab4f32d:

  • The CLI validates rename source and canonical unsigned name revisions using the existing validators. The focused parser behavior test covers both valid bounds and invalid inputs.
  • The rename sheet now uses existing localized product messages. Backend diagnostics stay in debug logs, and automatic refusals remain silent. The six localization catalogs pass parity across nine locales.
  • Automatic command encoding is now an instance method of the captured CloudAgentNameContext; the added static command-line extension was removed.
  • The proposed metadata-only Swift package is intentionally not being introduced. These values belong to the existing Cloud graph owner, while the context also depends on app-owned SurfaceProjection and CloudVMState. A narrow package would split the owner and conflict with the repository’s whole-domain package rule. No new public package API is added.
  • The terminal I/O and fixture compatibility repairs restore requirements needed to compile the existing hosted test target. They are isolated in separate commits; this PR’s behavior change remains rename authority and persistence.
  • The reported docstring percentage is not the repository requirement for internal app-target code. The authority, callback, compatibility, and persistence invariants are documented where owned; new public package symbols would require full DocC coverage.

The canonical branch autoreview and cmux policy check are clean on this commit, including the merge-conflict gate against origin/main. Hosted Swift validation and the unlaunched tagged rebuild are in progress. Rust workflow dispatch is currently returning GitHub 5xx responses; the previously passing daemon run is recorded separately from this final check.

Triage of the latest summary-level policy suggestions:

  • Type-level nonisolated is not valid on the supported Swift 6.0 macOS pathway, and this target does not enable default MainActor isolation. These plain Sendable value types retain their nonisolated boundary. Adding the proposed annotation would break the explicitly supported toolchain.
  • CloudRenameCoordinator owns and serializes the actual mutation tasks. The synchronous title setters require an async bridge; observeCloudNameWrite only forwards the result to a weak workspace reference. It does not own a competing name, retain the workspace, retry, or poll. Cloud commands have existing bounded connection/command timeouts. Retaining this small error observer avoids changing the synchronous title API throughout local/SSH owners.
  • The close/I/O methods restore missing upstream protocol implementations required to compile the app and test target. The historical close path and its batch complexity/error plumbing are retained in these compatibility repair commits. Reworking deletion batching or close error presentation is separate from rename authority; the newly added rename error sheet itself now uses localized, sanitized product text.
  • A metadata-only package and blanket internal-app docstring quota are not the repository architecture contract. The name values remain with the current graph owner; their invariants are documented. New package public API would receive full DocC coverage.

The substantive SDK compatibility finding is accepted. All public tab fields now come from RegistryTab.public_value, with authority inside the protocol’s existing extra map. Snapshots, mutation results, runtime projection updates, and journal deltas share the encoder; callers keep their existing focus/index behavior. The new compatibility regression validates actual mutation, snapshot, and journal values against the released strict field contract, and a Rust SDK test verifies extension metadata survives typed decoding.

Use localized catalog messages for v2WorkspaceSetAutoTitle errors.

The registered handler returns literal messages for disabled auto-naming, unavailable TabManager, invalid parameters, and missing workspaces. The catalog has no corresponding socket error keys. Use String(localized:defaultValue:) with matching catalog entries, as v2SurfaceSyncCodexNativeTitle does.
