Problem

Muse's official Windows launcher supports the same synchronous update controls as macOS/Linux, but T3 Code always treats Windows Muse installations as manual-only.

Change

Recognize the official batch shim and its adjacent PowerShell launcher, or a directly configured official PowerShell launcher. Require the official launcher structure, including its installation-relative synchronous update block, before enabling updates; marker-only and incomplete scripts stay manual-only. Run the verified installation through Windows PowerShell with -File and --version, so paths with spaces and shell metacharacters remain literal. Preserve the configured channel, forced update environment, and installation lock key. Standalone binaries and unrecognized wrappers remain manual-only; macOS/Linux behavior stays unchanged.

Scope and approval

This is a focused fix to existing Muse provider maintenance: the Windows launcher already implements synchronous updates, and T3's platform guard prevents that supported path from being used. It adds no settings, contracts, or client workflow.

Verification

• Added focused tests first: three positive Windows tests failed with null update capabilities before the fix.
• All 78 Muse package tests passed, including eight maintenance tests and a real Windows PowerShell fixture that runs both the direct invocation and the copied command from a path containing spaces, shell metacharacters, and all five PowerShell single-quote characters.
• Fixture output: --version|muse-canary|0|1|0|kept, confirming version arguments, channel, forced update variables, and preserved auth-path environment.
• Changed-file format/lint, Muse-scoped Knip, and typechecks for Muse plus its four affected dependents passed. vp run check:changed HEAD could not spawn vp on Windows; checks were run directly instead.
• The installed launcher was inspected read-only. An actual download-and-replacement update against a real Muse installation remains unverified; the developer's installation was not updated.

Model: gpt-6.1-sol. Harness: Codex in T3 Code.

Walkthrough

Muse now launches Windows PowerShell scripts for status checks and maintenance. Maintenance recognizes supported Windows shims and verified launcher scripts, then builds PowerShell update commands. Unsupported or unverified launchers remain manual-only.

Changes: Windows Muse launcher support

Layer / File(s)	Summary
PowerShell script resolution and status checks packages/provider-core/src/server/maintenanceResolver.ts, packages/provider-muse/src/server/sdk.ts, packages/provider-muse/src/server/sdk.test.ts, packages/provider-muse/src/server/status.ts, packages/provider-muse/src/server/status.test.ts	The maintenance resolver can restrict Windows command lookup to a declared script extension. Muse launches .ps1 paths through PowerShell, and status checks use the resulting command and arguments. Tests cover PowerShell launch arguments and status results.
Windows launcher verification packages/provider-muse/src/server/maintenance.ts, packages/provider-muse/src/server/maintenance.test.ts	The resolver recognizes supported Windows command shims and PowerShell launchers and validates launcher structure. Unsupported or incomplete launchers remain manual-only. Tests cover accepted and rejected launchers.
PowerShell maintenance command packages/provider-muse/src/server/maintenance.ts, packages/provider-muse/src/server/maintenance.test.ts	Verified launchers use PowerShell command and argument values with PowerShell quoting. Tests check environment values, arguments, and Windows execution.

A missing configured PowerShell launcher can incorrectly appear installed. This is a narrow status error that should be fixed, but it does not block the update workflow for valid launchers.

Explanation

The title "fix(muse): enable updates for official Windows launchers" matches the main change. The PR makes T3 Code treat official Windows Muse launchers as updatable instead of manual-only, and the raw summary shows maintenance resolution, launch, and status changes that support this. The title is specific and uses a conventional commit format.

Full details: Description check

Explanation

The description follows the template's main sections. Problem, Change, Scope and approval, and Verification are all present and filled in. The Problem and Change sections state the issue and the fix clearly. Scope explains why no prior issue is linked: it is a focused fix to existing provider maintenance and adds no settings, contracts, or client workflow. Verification lists the tests, the Windows PowerShell fixture output, the checks that ran, and what was not verified. It also gives the model and harness used. The template asks for a triaged issue or discussion link under Scope and approval, and the description does not provide one. It justifies the exemption instead, which the template allows for a very small, focused fix of an obvious bug. A reviewer may still question whether the change qualifies as small and obvious, given it spans several files and adds a new launch path.

thanks @Wiktor102. your official-launcher validation and powershell quoting are preserved, along with all three contributor commits. i merged current main and added the missing direct .ps1 path on this branch.

• .ps1 lookup works with default windows pathext, scoped to muse. sessions, version checks, and updates use the same powershell invocation.
• the shared invocation replaces duplicate maintenance code and preserves the host systemroot fallback.
• the batch shim and direct powershell launcher share one canonical installation lock.

verification on b6d3f24e1d7ddee6ae60f233e9760a4f3d9e74ea:

• regressions failed before each fix in existing test files; no new test files.
• blacksmith vp run check:changed 3f9448747bb8848050dc2cacf83affa6f94a66a1 passed format, lint, knip, 21 affected package typechecks, and 76 tests across four files.
• the current official launcher downloaded from meta resolves to no update on main and a powershell synchronous update command with this fix, using the public maintenance resolver.
• two independent code reviews approved this exact commit after one follow-up.

unverified: native windows execution, a real muse download/replacement, and the windows client update interaction. this linux vm cannot exercise those; windows-only test bodies were not executed here. no client UI code changed.

final ci: all 27 checks passed on this head. the unrelated attachment-preview comments test timed out once; its failed job and aggregate check passed on rerun. no web source was changed.

known minor limit from bot review, retained under the one-round-plus-follow-up cap: a nonexistent configured .ps1 can report "installed but failed to run" rather than "not found" because powershell itself starts. maintenance lookup still returns no update action for that missing file. valid launcher updates are unaffected.

Verified in a real dev environment

no changed runtime behavior could be verified on this linux boat vm. this is an environment limitation, not a passing verification.

read the description, complete diff, discussion, inline reviews, and commit authors at b6d3f24e1d7ddee6ae60f233e9760a4f3d9e74ea. the pr is open and contains no pr commits authored by juliusmarminge or t3dotgg. git.cafe reports 27 successful checks, zero failing and zero pending; those are ci results, not proof of the user flow.

ran uname -srm and checked executable availability:

Linux 6.8.0-117-generic x86_64
powershell.exe: unavailable
pwsh: unavailable
wine: unavailable
muse: unavailable

environment command transcript

Not verified

all changed behavior requires a windows server environment with a real muse installation: official .cmd/.bat shim recognition, direct .ps1 lookup, powershell status/session launching, synchronous download/replacement, copied command quoting, channel/environment preservation, and installation locking. the web client reaches maintenance through provider settings/update actions, but a linux-hosted server cannot exercise the windows branch. a codex turn here would exercise a different provider.

main reproduction, pr dev-server execution, real provider turns, neighboring runtime behaviors, and before/after recordings were not performed. no mocks, fixtures, platform overrides, or demo data were used as substitutes. no code changed, no commits pushed, and no dev servers started.

needed on windows: reproduce manual-only behavior on main with an official installation, then run this exact head and trigger the provider update from the client. verify a real replacement and subsequent muse session; repeat with a direct .ps1 path, and confirm standalone/unrecognized wrappers stay manual-only. also check the existing report that a missing .ps1 can be shown as installed-but-failed rather than not-found.

result: unverifiable on this vm.

Not verified

the changed execution paths require a windows server with a real muse installation. this includes official batch-shim recognition, direct powershell launcher lookup, status/session invocation, synchronous download and replacement, copied-command quoting, update environment/channel preservation, and installation locking. the user reaches updates through the client's provider update actions; the server's platform determines which launcher path runs. a codex turn on linux cannot exercise this muse/windows change.

main reproduction, installing and running main/pr dev servers, real provider turns, neighboring runtime behavior, and screenshots/recordings were not performed. this pass stopped before setup because neither main nor the pr can reach the changed windows path on this vm. no mocks, fixtures or platform overrides were substituted. no code changed and no server processes were started.

required follow-up on windows: reproduce manual-only updates on main, then run this exact head and update an official muse installation through the client. verify replacement and a subsequent session; repeat with a direct .ps1 path. check standalone/unrecognized wrappers remain manual-only, both launcher paths share a lock, and a missing .ps1 reports the appropriate installation status. the existing missing-script status review finding remains unverified here.

[Wiktor102]

Checked both CodeRabbit updates: the missing-script finding is confirmed addressed and the thread remains resolved.

The failed Test Server 5 job is an inherited main-branch test mismatch, not a Muse failure. VcsStatusBroadcaster.test.ts, in a HEAD watch ends when its git directory is removed, expects { refName: "main" }, while streamBranchStatus returns { refName: "main", isRepo: true }. The same mismatch exists on current main (fc2b5de20c); the test was added by #34774. CI runs the PR merge with main, which explains why this test is absent from the branch itself. I have kept that unrelated change out of this PR.

Re-ran check:changed on 509cb79640. Formatting, lint, knip, and affected typechecks pass. The same 7 local maintenance-resolver failures remain: these cases use POSIX executable fixtures or colon-separated paths on this Windows host. The resolver's script-extension override is absent for those package-tool cases, so it retains the existing lookup behavior. The 21 Muse SDK/status tests pass.
