Summary

Recover macOS in-place upgrades when OpenShell 0.0.85 cannot retire its gateway. The installer now stops identity-verified macOS gateway processes or Homebrew services, selects the checksum-verified Homebrew binaries, and recognizes trusted direct macOS gateway listeners. It also preserves the supported standalone macOS installation when Homebrew is absent by binding post-install binary selection to the verified installation method.

Fixes #10369
Fixes #10386

Changes

  • Add fail-closed macOS gateway retirement for an owned PID file and the trusted homebrew.mxcl.openshell user service.
  • Select both Homebrew OpenShell binaries after the pinned formula install succeeds, so stale user-local 0.0.85 binaries cannot shadow the verified installation.
  • Preserve the supported standalone macOS path without Homebrew by selecting both verified user-local binaries and warning that the gateway lacks reboot persistence.
  • Bind the macOS install method across install.sh and install-openshell.sh, and stop before recovery if the method changes or either required binary is missing.
  • Reuse the merged base-trusted installer and shared gateway resolver identities while keeping historical release fixtures unbound and rejecting the denied method-bound plus flat-path composition.
  • Use macOS lsof executable vnode evidence plus the target-bound process title to recognize a trusted direct gateway on an isolated port.
  • Revalidate the same process generation, command, and executable immediately before SIGTERM and SIGKILL, so a reused PID is never signaled.
  • Require diagnostic-free ps and lsof observations, preserve recovery state on ambiguity, and require a diagnostic-free lsof no-listener result before clearing a stale PID file.
  • Add focused tests for trusted, stale, malformed, symlinked, foreign-process, partial-observation, PID-reuse, wrong-service, Homebrew, standalone, and install-method-drift states.
  • Preserve the existing Linux /proc and systemd behavior.
  • Document verified Linux and macOS gateway retirement and fail-closed Homebrew binary selection.

Verification

  • PR description includes a Signed-off-by: line and every published commit appears as Verified in GitHub
  • Normal pre-commit, commit-msg, and pre-push hooks passed, or npm run validate:pr passed after refreshing origin/main when hooks were skipped or unavailable
  • Targeted behavior tests pass for the current change set, or tests are marked not applicable above - command/result or justification:
    • npx vitest run --project integration test/install/install-openshell-macos-upgrade.test.ts: 21 tests passed.
    • npx vitest run --project integration test/install/install-openshell-macos-upgrade.test.ts test/install/install-openshell-upgrade-prompt.test.ts test/install/install-openshell-gateway-service.test.ts test/install/installer-homebrew-formula-reuse-trust.test.ts test/install/installer-hash-check.test.ts test/install/installer-supervisor-manifest-trust.test.ts: 212 tests passed; 5 skipped.
    • npx vitest run --project cli src/lib/readiness/gateway-production.test.ts: 56 tests passed.
    • npm run source-shape:check: 52 valid exceptions; 0 invalid exceptions.
    • npm run checks:repository: passed, including dependency-pin consumers, source architecture, Vitest project membership, and test policy checks.
    • Bash syntax, Oxfmt, shfmt, ShellCheck, codebase growth guardrails, git diff --check, and all normal commit hooks passed.
    • Fresh independent documentation and security reviews passed for exact commit c7635ac684fa40ddebee136d2facc669cd0e4232.
    • Earlier qualification retained: gateway readiness and Homebrew service targets passed 129 tests; installer upgrade, gateway service, Homebrew trust, pin extraction, and dependency pin targets passed 198 tests; changed-test and repository checks passed.
    • Review hardening on Apple Silicon macOS: the active foreign launchd job remained running, bootout was not called, and a stale PID file with an active port listener preserved registration recovery and backups.
  • Applicable broad gate passed - npm test for broad runtime/test-harness changes; npm run check for repo-wide validation/coverage changes - command/result: npm test was attempted on the earlier candidate. The aggregate run exposed unrelated checkout/host failures: the user-local global npm lacks cacache, and existing corporate-CA environment leakage fails unrelated Dockerfile tests. The corporate-CA tests pass with NEMOCLAW_CORPORATE_CA_IMPORT=0; all changed and targeted projects pass.
  • Quality Gates section completed with required justifications or waivers
  • No secrets, API keys, or credentials committed
  • npm run docs builds without warnings (doc changes only) - result: 0 errors and 2 existing warnings.
  • Doc pages follow the style guide (doc changes only)
  • New doc pages include SPDX header and frontmatter (new pages only)
  • Documentation review: docs-updated
  • Documentation evidence: docs/manage-sandboxes/update-sandboxes.mdx and docs/reference/commands.mdx document verified Linux and macOS gateway retirement, the diagnostic-free lsof no-listener result, preservation of the PID file, OpenShell registration, and sandbox backups after an inconclusive observation, and fail-closed Homebrew binary selection. docs/reference/architecture.mdx already owns standalone macOS selection. The merged release-fixture adaptation changes tests only and adds no user setting or procedure. The documentation writer reviewed the complete diff and PR text for the commit under review against the writing and documentation contracts. Agent variant sync passed. npm run docs completed with 0 errors and 2 existing warnings. Focused validation passed 212 installer and trust tests with 5 skipped, 56 readiness tests, and 52 source-shape cases with 0 invalid. Repository checks and git diff --check passed.
  • Documentation agent: Codex Desktop subagent
  • Targeted validation: installer and trust integration tests passed 212 tests with 5 skipped; gateway readiness passed 56 tests; source-shape policy recorded 52 valid exceptions and 0 invalid exceptions; repository checks passed.
  • Security review: PASS. All nine categories passed for exact commit c7635ac684fa40ddebee136d2facc669cd0e4232. The repair requires owned PID or service state, exact executable and process-generation identity, diagnostic-free ps and lsof observations, revalidation before each signal, method-bound Homebrew or standalone binary selection, and preservation of the PID file, registration, and backups on ambiguity. The production parser and main-owned trust files match origin/main byte for byte; the release-fixture adaptation retains exact accepted identities and rejects unintended composition and arbitrary mutation.

macOS E2E

Host: h7yr45lq41.dyn.nvidia.com (Apple Silicon macOS 26.5.2, Colima).

Before the fix, a v0.0.90/OpenShell 0.0.85 worktree-CLI sandbox upgrade to v0.0.114 returned status 1 after backup:

Retiring OpenShell 0.0.85 gateway before installing current OpenShell…
Could not retire legacy gateway nemoclaw-20369 after backup.
NemoClaw: v0.0.114
OpenShell CLI and gateway: 0.0.85

With the patched worktree installer:

Pre-upgrade backup: 1 backed up, 0 failed, 0 skipped
Retiring OpenShell 0.0.85 gateway before installing current OpenShell…
Installing OpenShell from release 'v0.0.106'…
Downloading OpenShell Homebrew formula…
OpenShell Homebrew service staged; onboarding will start it after gateway validation.
OpenShell CLI: 0.0.106
OpenShell gateway: Connected, version 0.0.106
Gateway executable: /opt/homebrew/Cellar/openshell/0.0.106/bin/openshell-gateway

The legacy gateway retirement and pinned-formula trust paths passed without the circular checksum error. The later macOS/Colima Docker GPU-patch defect remains outside this PR and is separately tracked by #10348.

📝 Walkthrough

Walkthrough

The installer adds trusted macOS Homebrew OpenShell selection and legacy gateway retirement. Gateway readiness checks validate macOS executable identity. Tests cover process, PID-file, LaunchAgent, Homebrew, and readiness behavior.

Changes

macOS OpenShell lifecycle

Layer / File(s) Summary
Homebrew selection and handoff contract
handoff-issue-contract.md, scripts/install.sh, test/install/install-openshell-macos-upgrade.test.ts
The contract defines macOS upgrade, installation, checksum, evidence, and scope requirements. The installer selects verified Homebrew binaries and updates PATH. Tests verify the selected binaries.
Trusted gateway retirement
scripts/install.sh, test/install/install-openshell-macos-upgrade.test.ts
The installer validates macOS gateway processes, PID files, and Homebrew LaunchAgents before stopping them. Tests cover trusted, stale, malformed, symlinked, and foreign resources.
Platform-specific readiness validation
src/lib/readiness/gateway-production.ts, src/lib/readiness/gateway-production.test.ts, test/install/install-openshell-upgrade-prompt.test.ts
macOS uses lsof executable observations. Linux retains /proc generation checks and Docker environment validation. Tests cover trusted and foreign executable identities.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to 560c1

The PR improves macOS gateway retirement and verified binary selection, with targeted tests and macOS upgrade validation passing. It is mergeable with owner awareness that one upgrade-test fixture depends on /usr/bin/python3 and may fail before testing installer behavior on hosts where that executable is unavailable.

[P1] Preserve the supported standalone macOS install path

scripts/install-openshell.sh still returns success on macOS without Homebrew after installing and checksum-verifying the standalone CLI and gateway assets (and explicitly documents that supported no-reboot-persistence path). This new unconditional Darwin branch then calls prefer_homebrew_openshell verified-install and aborts even when the newly installed ~/.local/bin/openshell and openshell-gateway are executable. I reproduced this at the exact head by simulating a successful spin with both standalone binaries present and no brew on PATH; maybe_install_openshell_during_install force exits 1 with the new Homebrew-only error. This breaks fresh/forced installs on every supported no-Homebrew macOS host. Please retain strict Homebrew selection only when the install actually used Homebrew, select the verified standalone binaries otherwise, and add a regression covering the successful no-Homebrew result.

When the installed OpenShell version is already supported, the installer keeps the running gateway through the host update.
On Linux, if installed OpenShell lifecycle commands cannot retire the gateway, the installer checks a verified NemoClaw-managed gateway PID file for any configured gateway port.
For the default gateway on port `8080`, the installer first checks a verified active `nemoclaw-openshell-gateway.service`, then checks the PID file.
On Linux and macOS, if installed OpenShell lifecycle commands cannot retire the gateway, the installer uses verified NemoClaw-managed service or PID-file evidence for the supported recovery path.

[P2] Keep the operational upgrade guide in sync

This page now describes the macOS Homebrew-service and PID-file recovery path, but docs/manage-sandboxes/update-sandboxes.mdx:81-86 still says the fallback is Linux-only and describes only systemd. That is the operator-facing upgrade/recovery procedure, so macOS users are given conflicting support and recovery guidance. Please update that page with the same macOS service/PID fallback and fail-closed lsof preservation behavior, then run the docs validation.

## Outcome

The base-trusted OpenShell installer parser recognizes the one combined
macOS method-bound and development MUSL template reviewed for PR #10484.
It retains the six identities from current `main` and denies unlisted or
unintended template compositions.

## Reason

NemoClaw verifies pull request installers with parser code from the PR
base. The trust anchor rollout is intentionally two-step, so this
identity must land before #10484 can pass the fail-closed installer hash
gate.

### Related issues

Part of #10369

Unblocks #10484. Depends on the trust-test ownership established by
merged PR #10566.

## Changes

- Add only SHA-256 identity
`4b45161017a5936331300e982168160575701632711328cbbb97480eb087fb51` for
the reviewed combined template.
- Retain the six OpenShell 0.0.106 identities from current `main` and
omit four obsolete candidate-only identities.
- Add positive validator evidence for current development MUSL,
historical flat-path development MUSL, and combined method-bound
development MUSL templates.
- Add denial evidence for the combined method-bound template with
obsolete flat test paths and for arbitrary byte mutation.

## Verification

- `npx vitest run --project integration
test/install/installer-homebrew-formula-reuse-trust.test.ts
test/install/installer-hash-check.test.ts
test/automation/pull-requests/growth-guardrails.test.ts` - 121 tests
passed during implementation validation.
- `npm run source-shape:check` - 51 valid exceptions, 0 unapproved
cases, and 0 invalid exceptions.
- `npm run checks:repository` - passed.
- `git diff --check` - passed.
- Normal pre-commit and commit-msg hooks passed. The normal pre-push CLI
TypeScript hook passed.
- GitHub marks every commit in the PR as Verified, including new commits
`719a1a0967e112376b55c4f168e1d4f61a0d0808` and
`8992074fdf40bcffbfe69961714b8451bce62fa2`.
- The diff contains no secrets, API keys, or credentials.

## Review notes

- Independent nine-category security review passed for commit under
review `8992074fdf40bcffbfe69961714b8451bce62fa2` with no findings. The
reviewer independently reran 128 tests and the source-shape check.
- The parser remains base-trusted. Only the reviewed combined template
is added; unintended composition and byte mutation fail closed.
- This PR changes no installer runtime behavior and has no user-visible
documentation impact.

<!-- nemoclaw-docs-review:start -->
- Documentation review: `docs-not-needed`
- Documentation evidence: An independent documentation writer reviewed
the complete three-file diff for commit under review
`8992074fdf40bcffbfe69961714b8451bce62fa2`. The change authorizes one
reviewed combined macOS method-bound and development MUSL
installer-template identity, retains the six identities from current
`origin/main`, excludes four obsolete candidate-only identities, and
adds positive and denial-path validator evidence. It changes no command,
configuration, workflow, error, documentation route, or supported user
behavior. Evidence includes 121 focused integration tests passing, 51
valid and 0 invalid source-shape exceptions, repository checks and hooks
passing, `git diff --check` passing, and a clean worktree.

Request changes on exact head 909de25c9e3c0d2ccd59e767fb919a01a2dc2a05. The original standalone-macOS and documentation blockers are resolved, and the focused macOS recovery suite passes 21/21. The current base merge introduced one new fail-closed trust blocker: the 0.0.106 template ledger, reconstruction test, and source-shape exception no longer describe the combined current installer. Required static checks and CLI shards 3/11 fail; locally the focused trust test fails 6/10. Reconcile the approved template history against current main and add or revise the regression mapping; do not merely admit the observed hashes. All commits are Verified, DCO is green, and no separate blocker appeared in the nine-category security review.

[P1] Reconcile the combined installer template trust mapping

The merged constructor/digest table no longer represents the current installer templates. On this commit the downstream and strings preflight constructions produce untrusted hashes 6eeeafebfb3714962577b4d3d8c7ca2628da98f133755f9ff9549a2c03df1ebd and ccb9fd981d66aaac41f8bf74262fc8d6a24229d0f3c416daf1b9d15af15e1326; two historical cases map to different trusted hashes, the prospective MUSL replacement matches no source block, and a case labeled unreviewed is accepted. This makes extract-installer-pins.mts fail closed across the installer hash suite and leaves required CI red. Rebuild the table from the combined current-main transitions, tie every digest to one reviewed constructor, align ci/source-shape-test-budget.json with the current test title, and retain a one-byte mutation rejection test. Local result: 6/10 failed.

Approved exact head c7635ac. The prior installer-template trust blocker is resolved: every admitted 0.0.106 shape maps to a reviewed constructor, negative mutation and composition cases remain fail-closed, and the exact parser emits the expected current template identity. Exact-head local verification passed 104 trust tests, 108 macOS upgrade tests, repository architecture checks, source-shape checks, and diff hygiene. All 17 commits are GitHub Verified; DCO and required CI are green; CodeRabbit has no current actionable thread; the nine-category security review found no in-scope blocker after checking every Advisor specialist.
