fix: restore main compile (OpenCodePaths in CLI, Codex auto-naming scope)

[lawrencecchen]

Main does not compile since #16229 and #16201, so every nightly run since 18:35 UTC fails at Build nightly app (Release):

• CLI/cmux.swift:40477: cannot find 'OpenCodePaths' in scope: the enum lived in Sources/, which the CLI target does not build. It moves to CMUXAgentLaunch, which both targets import.
• CLI/CMUXCLI+AutoNaming.swift:271: cannot find 'usesTemporaryConfig' in scope: the private providerOverrides now receives the flag. Folded in from Pass the temporary-config flag to the Codex provider override parser #16243, since neither fix compiles without the other.

Summary by CodeRabbit

• Improvements
  • OpenCode configuration and database locations now use explicit OpenCode overrides first, then XDG locations, and finally standard home-directory paths. Blank environment values are ignored, and tilde-based paths are expanded.
  • With temporary Codex configuration, provider settings come from the configuration file rather than command-line overrides, while the selected provider and model are preserved.
• Bug Fixes
  • Cloud workspace projection updates now stop when repeated reconciliation makes no progress, while still allowing progress and restarting the limit for new graph states.
  • Reusing a remote view at its current placement no longer triggers an unnecessary projection update.

📝 Walkthrough

Walkthrough

The change adds shared OpenCode path resolution and updates its callers. It bounds cloud projection reconciliation and avoids redundant projection updates. It also changes temporary-config provider overrides, artifact publishing environment checks, and sidebar test option types.

Changes

OpenCode path resolution

Layer / File(s)	Summary
Add and adopt OpenCode path resolution Packages/macOS/CMUXAgentLaunch/Sources/CMUXAgentLaunch/OpenCodePaths.swift, Sources/SessionIndexModels.swift, CLI/cmux.swift, cmuxTests/OpenCodeHookRegressionTests.swift	OpenCodePaths resolves config and database URLs from overrides, XDG paths, and home-directory defaults. Session indexing and the CLI use its instance properties. Regression tests use the new API.

Cloud projection reconciliation

Layer / File(s)	Summary
Bound reconciliation and projection updates Sources/Surfaces/CloudWorkspaceProjectionCoordinator.swift, Sources/Surfaces/SurfaceCatalog.swift, cmuxTests/CloudWorkspaceLiveProjectionTests.swift	Reconciliation stops after repeated idle marks or more than 64 passes for a state. Projection placement updates skip unchanged coordinates, and tests cover reuse and reconciliation limits.

Codex auto-naming overrides

Layer / File(s)	Summary
Condition provider overrides on temporary config CLI/CMUXCLI+AutoNaming.swift, cmuxCLITests/CodexAutoNamingArgumentsTests.swift	The override builder receives the temporary-config flag. The test checks that base_url is omitted from command-line overrides when a temporary config is used.

Artifact publishing environment

Layer / File(s)	Summary
Set and validate artifact environment .github/workflows/cmux-tui-artifacts.yml, tests/test_ci_production_secrets_protected_env.py	The publish job uses the artifacts environment. The CI test checks that environment and limits referenced secrets to the configured R2 upload credentials.

Sidebar test options

Layer / File(s)	Summary
Update sidebar appearance test setup cmuxTests/SidebarWidthPolicyTests.swift	The sidebar appearance test setup uses WindowChromeSidebar option types.

Change: Bug fix

Merge Risk: ⚪ Minimal · up to 5e916

The shared path resolver, bounded reconciliation, and configuration updates have no established blocking defects. Merge after normal build and test checks.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 5e916

The main concern is extending binary-publishing access to helper branches without demonstrated separation from production artifact write authority. The local path-resolution and projection changes preserve the examined ownership controls, but publishing permissions and approval requirements need confirmation.

Retained concerns

• Medium · security · inferred: The publishing job moves to an environment declared to allow helper branches while receiving credentials used to upload into the production binary bucket. A party able to edit and dispatch an admitted helper-branch workflow could inherit production-object write authority unless external approvals or storage permissions prevent it. The new secret-name allowlist does not enforce that separation; effective branch protections and R2 permissions remain unverified.

Security review details

Security Blast Radius

• inferred — Misuse of the publishing credentials could affect shared binary distribution rather than only a helper-branch build. The workflow targets cmux-binaries for TUI and relay artifacts and describes cloud installers and application bundling as consumers. Effective key scope and downstream rejection controls remain unverified, so fleet-wide compromise is a possible consequence, not an established outcome.

Security Findings and Attack Paths

• inferred — The conditional attack path requires authority to alter and dispatch a workflow on an admitted helper branch, obtain its environment credentials and use those credentials outside the intended commit-addressed upload logic. The PR widens declared branch eligibility compared with release. No verified exploitation or retained Security finding is supplied.

Trust Boundaries and Controls

• observed — Publishing excludes pull-request events, checkout disables persisted credentials, manifests undergo verification and provenance attestation, and commit-addressed uploads request write-once behavior. These are relevant controls, but do not demonstrate separation of helper-branch credentials from production-object authority.
• observed — The shared OpenCode resolver computes URLs without performing I/O. Environment-selected paths predate this PR, and the examined CLI plugin installation and removal paths retain marker checks and installation confirmation behavior. No new environment-to-filesystem authority was identified in those callers.

Resilience and Maintainability Implications

• observed — The post-await isCurrent check does not include observation freshness in either the reviewed base or head. Freshness can change separately from graph identity. This is a preexisting transition-proof limitation, not an introduced PR concern; no runtime reproduction or increased exposure was established.

Hardening Proposals

• proposed — Separate helper-branch publication authority from mutable production distribution, using an independently enforced storage boundary or a trusted promotion step. Confirm deployed environment approvals and credential permissions rather than relying on branch-editable upload logic or secret-name checks.

Full details: Docstring Coverage

Explanation

Docstring coverage is 29.63% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 27 functions across 10 files. (2 skipped: 1 unsupported, 1 too large.)

Full details: Cmux Swift Package Boundaries

Explanation

The diff adds CloudWorkspaceReconcileBudget in Sources/Surfaces/CloudWorkspaceProjectionCoordinator.swift (head lines 213–238). This is pure cloud reconciliation state logic with an Equatable mark and direct unit tests in cmuxTests/CloudWorkspaceLiveProjectionTests.swift; it does not require AppKit, SwiftUI, Ghostty, or app singletons. The surrounding coordinator may remain app composition, but this independently testable domain logic is kept in the app target. The OpenCodePaths move is compliant because the value now lives in the CMUXAgentLaunch SwiftPM target.

Resolution

Extract CloudWorkspaceReconcileBudget and its Mark input model from Sources/Surfaces into a small SwiftPM target, preferably CmuxCloudProjection depending on CmuxSurfaceCatalogModel (or an equivalent extension of that existing package). Expose CloudWorkspaceReconcileBudget as the first public type, and move or abstract the binding snapshot value needed by Mark. Keep CloudWorkspaceProjectionCoordinator, SurfaceCatalog mutation, Sentry reporting, and native workspace callbacks in the app target.

Full details: Description check

Explanation

The description explains the compile failures and intended fixes, and it includes a changelog entry. It does not include the required Testing section or Checklist, and it does not state what verification ran or what remains unverified.

Resolution

Add the required Summary, Testing, Changelog, Demo Video, and Checklist sections. In Testing, list the exact build or test commands that passed and identify any pending verification. State that a demo is not applicable if no user-facing behavior changed, and complete the checklist items or explain why they do not apply.

[teamleaderleo]

Independent confirmation of the auto-naming half, and a note on blast radius.

At origin/main 71bb553867c, CLI/CMUXCLI+AutoNaming.swift:271 is guard !usesTemporaryConfig else { return result } inside providerOverrides(from:), which takes no such parameter. The only declarations are build(configToml:usesTemporaryConfig:) at 217 and the call site in CMUXCLI+AutoNamingDispatch.swift:183, so there is no property for 271 to resolve against. a4e862d030f (#16201) added the guard; it compiles only in a shape of providerOverrides that main does not have.

Blast radius, in case it helps prioritize: this fails macos / macOS compile admission for any PR that routes the macOS lane, and because the compile never yields a product, CLI product tests is skipped rather than failed. On my #16264 that cascades into macOS status, tests and required ci-status. I was attributing reds across two other PRs this evening and this one is the newest layer, so a green here unblocks a lot of unrelated branches at once.

Nothing needed from me; flagging the reach rather than the fix.

Dogfood tours of 5e916469

cloud-sidebar-audit-tour at 5e916469: 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.}

[teamleaderleo]

Heads up that this is necessary but not sufficient for the app-host lane. The admission run on 5e916469 no longer reports usesTemporaryConfig, so this PR does fix that one, but 25 other errors remain in Compile app-host test product, across PaneResizeShortcutTests, LastSurfaceClosePreferenceTests, WorkspaceCloseTabsContextMenuTests and CLIVMTransferTests. They come from #15420 and #15381, and #16245 fixes all of them. Whichever of the two lands second is the one that turns the lane green, so this PR's own CI will stay red until #16245 is in. Attribution for each error is on #16245.

main no longer compiles after this merge

@lawrencecchen: after ca831d4282 landed on main, the app-host test product (the app and cmuxTests, build-for-testing) stops compiling. These errors first show up in a range of 1 merges (488eaf71d8..ca831d4282), and this pull request's diff is the one that reaches them. The other merges in that range () are being compiled on their own to confirm.
