not compete for credentials. Add a test covering one defined and one undefined

#12015) ## Outcome This PR now carries two accepted installer fixes: - NemoClaw transfers protected managed-startup receipts on Docker Engine 27 without the daemon interpreting a numeric UID:GID pair as a passwd entry. - On macOS, operators can explicitly request a force-fresh reinstall that removes NemoClaw/OpenShell-managed state through the canonical whole-host uninstaller, keeps model caches, and starts fresh onboarding. Fixes #12010 Resolves #12076 ## Accepted stacked decision Accepted product decision: #12076; explicit maintainer acceptance: https:\/\/github.com\/NVIDIA\/NemoClaw\/issues\/12076#issuecomment-5737074714. PR #12041 is the stacked implementation that was explicitly merged into this branch by the accountable maintainer. - **Consumer:** macOS operators recovering an interrupted or internally inconsistent NemoClaw/OpenShell installation. - **Owner:** the hosted installer orchestrates staging and reinstall; the canonical staged `internal uninstall run-plan --all-gateway-ports --destroy-user-data` remains the only state/resource deletion authority. - **Lifecycle:** the reset runs before CLI installation and bypasses legacy backup/recovery only when `--force-fresh-install` or `NEMOCLAW_FORCE_FRESH_INSTALL=1` is explicit. - **Compatibility:** the option is limited to Apple silicon macOS. Persisted local Colima contexts resolve to an authoritative Unix socket and remain selected through recovery and onboarding. - **Security and recovery:** Docker-only labels, names, and image references are not deletion authority. Recognizable residue without trusted host state blocks reset for explicit reconciliation. If canonical uninstall is incomplete, the installer stops and preserves remaining state for retry. Model caches and unrelated `nemoclaw-acp` files remain. - **Validation contract:** public-flag lifecycle ordering, failure preservation, fail-closed Docker residue detection, deferred Colima recovery, Homebrew removal, platform scope, staged-source isolation, Docker 27 receipt transfer, and workflow-level cancellation cleanup are checked in. ## Changes ### Docker Engine 27 receipt compatibility - Create only the Docker receipt seed container with numeric root user `0` instead of `0:0`. - Preserve `docker cp -a`, the Docker-managed volume, and the seed security controls: no network, read-only root filesystem, `no-new-privileges`, and no capabilities. - Label receipt volumes for diagnostics and inventory. Force-reset does not treat the mutable label as deletion authority; UUID-shaped receipt volumes block cleanup for explicit reconciliation. - Require the exact `--user 0` argument in unit coverage and reject regression to `0:0`. - Add a pinned Docker Engine 27.5.1 archive-copy boundary to the protected multi-architecture managed-image startup selector. - Verify ownership, modes, read-only mounting, isolation controls, successful cleanup, failed-transfer cleanup, and exact platform-scoped daemon identity. - Add an always-running workflow cleanup step so cancellation cannot strand the privileged Docker 27 daemon. - Let the receipt-probe script derive the daemon name from validated run ID, attempt, and platform inputs for both probe and cleanup; remove workflow and fixture copies of the naming rule. - Require the seed itself to be non-privileged and accept cleanup only when Docker explicitly reports the container or volume absent; timeouts, daemon errors, and permission errors fail the proof. - Refresh the reviewed managed-startup runtime hash after current `main` regenerated that artifact without updating its exact-hash contract. ### Force-fresh macOS reset - Add `--force-fresh-install` and `NEMOCLAW_FORCE_FRESH_INSTALL=1` to the hosted and versioned installer. - Stage and build the selected candidate outside the active state root before cleanup. - Keep the maintained `lkg` downgrade guard active for force-fresh requests; an intentional downgrade still requires an explicit immutable release tag. - Bound OpenClaw pre-extraction, staged-uninstaller preparation, ownership preflight, and authoritative cleanup per process group; timeout kills and reaps descendants, blocks package removal, and reports incomplete cleanup when destructive work may have started. - Run destructive cleanup only through the staged canonical all-gateway uninstaller. - Pass its hidden force-reset mode through every gateway-port child. The standalone installer records a digest manifest for managed user-local OpenShell binaries; canonical cleanup removes only matching binaries, preserves foreign or changed files, and removes the manifest after complete cleanup. Mutable Docker receipt labels are diagnostic only, and inconclusive cleanup returns failure. - Stop before Homebrew/package removal when the authoritative uninstall is incomplete; do not erase recovery state after a failed sandbox or Docker cleanup. - Remove the duplicate installer-owned process, sandbox, Docker, and state deletion implementation. - Preserve and fail closed on receipt volumes or Docker-only containers identified only by mutable labels, names, or image references. Stop before cleanup when Docker is unavailable or residue lacks trusted host state. - Keep the resolved Colima `DOCKER_HOST` authoritative after deferred Node.js installation by leaving `DOCKER_CONTEXT` unset. - Document the macOS-only destructive scope, preserved model caches, environment equivalent, safe invocation, and fail-closed behavior. ## Verification Candidate: `a9bd2f8bd5749c00764430a24f8943d1267c2666`; canonical base at publication: `20f7b2c9f883901d28f7fbf4f95e44ab38bb9c06`. - Focused installer, Colima recovery, Docker 27 cleanup contract, and protected workflow suites: 4 files and 109 tests passed. - Focused maintained-downgrade and bounded force-reset preparation suites: 2 files and 91 tests passed. - Final Advisor repair batch: 4 files and 144 tests passed. - Canonical uninstall ownership and residual-volume batch: 6 files and 65 tests passed; the final structural refactor: 5 files and 56 tests passed. - Receipt ownership, Docker-only detection, environment routing, help, and growth-guard batch: 4 files and 45 tests passed. - Labelled volume fixture compatibility: 2 files and 13 tests passed. - Managed OpenShell binary ownership and remaining-PATH rejection: 3 files and 38 tests passed. - Protected OpenShell installer template remained at its base-trusted digest; installer hash validation and its 3 trust regressions passed. - Legacy pre-label receipt-volume detection fails closed before any cleanup; the focused receipt regressions and full 33-test installer/growth batch passed. - CodeRabbit cleanup repair batch: 3 files and 46 tests passed; the wider uninstall sweep passed 530 tests, and its lone suite-load timeout passed on exact retry. - Docker planned-volume absence is accepted only for exact daemon not-found evidence; deletion and inconclusive-inspection regressions plus growth guardrails passed in an 18-test batch. - Advisor ownership repair: Docker-only label/name/image residue is preserved and blocks force-fresh until explicitly reconciled; label alone is not deletion authority. - Docker absence verification captures stdout/stderr for both container and volume inspections; focused proof plus growth guardrails passed 19 tests. - XDG user-bin routing and four-helper standalone manifests feed a read-only staged canonical ownership preflight before deletion; malformed or mismatched manifests stop cleanup at that single owner. - Merged `main` at `20f7b2c9f883901d28f7fbf4f95e44ab38bb9c06` (OpenClaw 2026.9.1); kept direct runtime-bundle hash enforcement at the regenerated `b6363673…` digest. The merged contract and focused suites passed 67 tests. - Latest merged-main ownership/image-removal repair: 51 focused tests, 137 affected tests after #12082/#12083, and `npm run validate:pr` passed. - Canonical ownership-preflight and convention-safe cleanup repair: 62 focused tests, `npm run docs`, installer hash verification, and `npm run validate:pr` passed. - Merged-main #11917 compatibility plus the explicit Docker-inventory assertion: 131 affected tests and `npm run validate:pr` passed. - Bounded ownership/cleanup process groups and label-neutral receipt preservation: 51 focused tests, descendant-reaping assertions, TypeScript, and `npm run validate:pr` passed. - Direct canonical receipt inventory covers every volume name, with labelled and unlabelled preservation regressions; focused tests, TypeScript, and `npm run validate:pr` passed. - `npm run docs` — passed, including generated variants, routes, links, and MDX validation. - `bash -n scripts/install.sh` — passed. - `shellcheck scripts/install.sh` — passed. - `npm run source-shape:check` — passed without increasing the budget. - `npm run validate:pr` — passed, including formatting, lint, repository policy, E2E phase semantics, growth guardrails, secret scanning, publication validation, builds, and CLI typechecking. - Prior live Docker Engine 27.5.1 arm64 compatibility evidence reproduced the `0:0` passwd failure, passed with user `0`, verified ownership and modes, enforced the read-only mount, and verified success/failure cleanup. - Prior live macOS/Colima force-fresh evidence completed successfully while preserving the model cache. - Exact-head GitHub CI and Advisor verification are pending for this candidate. ## Scope The receipt change remains the narrow fix requested by #12010. The additional force-fresh surface is the explicitly accepted and merged scope from #12041. The current follow-up removes duplicate deletion authority, fails closed on incomplete cleanup, preserves the validated Colima target, adds missing operational documentation, and closes the workflow cancellation leak identified by exact-head review. --- Signed-off-by: Aaron Erickson <aerickson@nvidia.com> <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit - **New Features** - Added force-fresh installation support for Apple silicon macOS through the CLI and environment variable. - Fresh installation can remove verified managed NemoClaw/OpenShell state while preserving model caches and unrelated tools. - Added recovery support for validated local Docker socket contexts. - **Bug Fixes** - Cleanup now stops safely when ownership or Docker resource verification is inconclusive. - Improved receipt-volume handling and multi-architecture startup cleanup. - Prevented unintended downgrades and preserved foreign executables, containers, and images. - Artifact verification now always checks declared runtime hashes directly. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Signed-off-by: Aaron Erickson <aerickson@nvidia.com> Signed-off-by: Rebecca Sliter <571084+rsliter@users.noreply.github.com> Co-authored-by: github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com> Co-authored-by: Rebecca Sliter <571084+rsliter@users.noreply.github.com>

Outcome
MCP registration now rejects two credential-bound aliases that resolve to the same normalized endpoint but request different credential providers. The rejection occurs during preflight, before any provider or sandbox policy mutation, while distinct MCP endpoints and unauthenticated aliases remain supported.
Reason
OpenShell identifies network policy targets by host, port, and path. Two aliases for the same target cannot safely select different credential providers, so attempting to install both produces an ambiguous policy and a late timeout. Failing early makes that security boundary explicit and avoids partially mutating registration state.

This change does not add multi-binding support for one endpoint. Supporting that behavior would require an explicit aggregate or multi-provider credential design in OpenShell. This PR makes the current policy model deterministic and safe.
