ApprovabilityVerdict: Not approved Macroscope's review found this PR not approvable — This PR introduces a substantial native Muse provider with new subprocess execution, permissions, workflow handling, credential/MCP integration, settings, and model behavior. It also changes product defaults and adds static-analysis suppression directives, so the scope and policy-sensitive changes require human review. Not approved because:

Each workflow child becomes a provider-native subagent nested under the
workflow row, with live status and Muse's label ("Agent N" when Muse sends
none). Muse exposes no child conversations, so they have no child thread. The
workflow row takes the workflow's name, and the launching tool call no longer
shows as a second row. Re-records muse_workflow with two agents.

Preserve workflow-agent labels across child updates.
When Muse omits child.label on a later workflow revision, this line replaces ping and pong with Agent 1 and Agent 2. The recorded transcript shows that sequence: labels appear in the initial child snapshots, then disappear before completion. Retain each child's last nonempty label, and use the fallback only if Muse has never supplied one.

Upstream's native Muse provider (pingdotgg#17082) records the full runtime instructions in its replay fixtures, so Cody's final-answer block made every Muse replay scenario fail. The fixtures now include it.

T3 Code could not run Muse Code. Muse speaks its own protocol (MSP over
muse serve), not ACP, so the Local ACP command path does not work for it. This adds Muse as a native provider. It is off by default and marked Beta.This takes over #15123 by @grodriguez-fr, which builds on @cristianuibar's #11392. Their commit is kept as-is with authorship. The commits after it rebase it onto current

Muse now runs through

Only the pipe underneath is replayed.record:muse-replay(scripts/record-muse-msp-replay-fixture.ts) runs a fixture through the real orchestrator against a livemuse serve. It records every line, makes the workspace and home paths portable, then replays the result through the fixture's assertions before writing it.simple,multi_turn,turn_interrupt,muse_permission, andmuse_workflow. Inmuse_permission, Supervised mode approves one command and declines another.muse_workflowlaunches a two-agent background workflow and gets its report back.

The Muse unit and contract tests pass, and server, web, mobile, and contracts typecheck clean.Not verified: the web, desktop, and mobile UI were not tested in this rebase; the UI code is unchanged from #15123. No fixture records resume after a T3 server restart yet; a unit test covers it.
