Carry the CMUX side of fleet machine onboarding on top of the canonical workload-profile contract from #13411.

This PR is intentionally thin now:

  • cmux_macos_native_build accepts cmux.macos.dev-check@1;
  • cmux_linux_ci accepts cmux.ci.guard@1;
  • CMUX owns workload commands, semantic validation, artifact identity, timeout, and pass/fail semantics through scripts/ci/cmux_workload_profile.py;
  • Glaeda owns enrollment, exact semantic-result binding, durable lifecycle state, candidate eligibility, and fresh local admission;
  • the transitional duplicate fleet_acceptance.py implementation and role-specific wrappers have been removed from this PR.

Glaeda implementation: teamleaderleo/glaeda#1067.
Provider-neutral CMUX request adapter: teamleaderleo/glaeda#1071.
Multi-orchestrator lease boundary: teamleaderleo/glaeda#1057.

Docs-only relative to #13411; no direct required-CI routing change.

Merge Risk: 🟡 Moderate · up to 4cbcc

The new onboarding path cannot run its macOS acceptance workload as written, and its named platform launchers can be redirected to a different role or checkout. Fix those acceptance and launcher defects before merging; the remaining test and documentation issues also need correction for reliable validation and usable guidance.

Explanation

Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 26 functions across 2 files. (5 skipped: 5 unsupported.)

Full details: Description check

Explanation

The description is incomplete and conflicts with the changeset. It claims the acceptance implementation and wrappers were removed, but the pull request adds them. It also omits the required Summary, Testing, Demo Video, Review Trigger, and Checklist sections.

Resolution

Rewrite the description to match the implemented acceptance harness, scripts, tests, and documentation. Add the required template sections, provide test and verification details, complete the checklist, and include the review-trigger block or explain any non-applicable sections.

The PR should not merge until the operational recovery and rollback snippets work from a fresh shell or after reboot.

Findings

  1. P1 Recovery Variables Do Not Persist ▶

Summary

This PR documents the CMUX side of fleet-machine onboarding and assigns semantic workload ownership to canonical workload profiles while leaving enrollment and lifecycle ownership with Glaeda.

  • Adds Mac and Linux fleet-role-to-profile bindings.
  • Documents bootstrap, enrollment, workload execution, acceptance, eligibility, lifecycle operations, rollback, and cleanup.
  • Clarifies that enrollment does not alter required-CI runner routing.
  • The lifecycle and rollback snippets need to reconstruct their durable paths instead of relying on variables from the original onboarding shell.

- Line 124: Replace the literal \n\n before the “CMUX-owned machine enrollment”
heading with two actual blank lines so Markdown recognizes the heading
correctly.

In `@scripts/fleet_acceptance.py`:
- Around line 430-433: The acceptance checks currently duplicate workload and
archive-success signals. Update the logic around workload_ok, semantic, and
artifact_ok so semantic independently validates expected PASS: output from
tests/test_ci_self_hosted_guard.sh, while the artifact check verifies a known
file from the requested commit exists under work rather than only checking the
archive; preserve the receipt’s four distinct check results.
- Around line 335-339: Update mac_toolchain() and its
cmux_required_zig_version() dependency to use the intended existing Zig manifest
path, or ensure ghostty/build.zig.zon is provisioned before the helper reads it,
so macOS acceptance does not fail with FileNotFoundError and status 2.

In `@scripts/fleet-accept-linux-ci`:
- Around line 1-4: Set the executable permission (mode 100755) on both launcher
files: scripts/fleet-accept-linux-ci (lines 1-4) and
scripts/fleet-accept-macos-native-build (lines 1-4). No content changes are
required; ensure both are executable when committed.
- Line 4: Update both launcher scripts to inspect forwarded arguments before
exec and reject any caller-supplied --role or --repo-root options, including
their associated values, before invoking the fixed entrypoint configuration.
Preserve each launcher’s hard-coded role and repository root while forwarding
all unrelated arguments unchanged.

In `@tests/test_fleet_acceptance.py`:
- Around line 70-77: Update test_settlement_catches_background_child to use a
long-lived background sleep process instead of sleep 0.2, such as sleep 3600, so
the process-group settlement probe reliably detects the remaining child while
preserving the existing assertions.

Coordination update from #13411 / teamleaderleo/glaeda#1071: machine acceptance now has stable CMUX-owned workload identities.

Target mapping:

  • cmux_macos_native_build -> cmux.macos.dev-check@1
  • cmux_linux_ci -> cmux.ci.guard@1

The acceptance harness should ultimately invoke the checked-in profile runner at the exact accepted source and bind its canonical cmux-workload-result/v1 digest, while this PR continues to own machine/enrollment/toolchain/process-settlement evidence.

That removes the duplicated long-term acceptance recipe and keeps “passing CMUX” inside this repository. The existing direct recipes can remain transitional implementation while the profile PR lands, then be reduced to the generic profile invocation plus physical checks.
