Austin Local Orchestrator — Custom Vibe Island fixture

This candidate is a clean-room, local fixture export for a Mac-first companion surface that helps coordinate multiple coding-agent systems while exposing usage/context savings and fail-closed approval evidence.

It is not a production app, runtime, router, app-server, device companion, or distribution package. Codex, Hermes, and other engines remain replaceable execution capabilities; the companion surface does not become a shell, unrestricted executor, approval-policy owner, or permanent runtime master.

Included

• Swift domain contracts and a fixture-driven macOS menu-bar shell.
• Python M0 contract fixtures for immutable events, bounded discovery, context savings, handoffs, receipts, and security states.
• A separate sanitized Vibe/Hermes event and companion-action fixture contract.
• Accepted architecture ADRs and local build/test instructions.

Local verification

From this directory:

python3 -m unittest discover -s Tests -v
swiftc -typecheck Sources/VibeCore/VibeCore.swift
swiftc Sources/VibeCore/VibeCore.swift Tools/VibeCoreSmoke/main.swift -o /tmp/vibe-core-smoke
/tmp/vibe-core-smoke
./script/build_and_run.sh

The build helper creates a local fixture bundle but does not launch it unless passed --run. The canonical source verification recorded in VERIFICATION.md was no-launch and confirmed the app was not running.

The companion contract can be verified independently:

cd contracts/vibe-hermex-event-contract-v1
PYTHONDONTWRITEBYTECODE=1 python3 -B -m unittest discover -s tests -v

Safety and provenance

This export contains no credentials, private campaign/finance material, live transcripts, machine state, DMGs, build outputs, third-party source snapshots, or proprietary assets/interfaces. See PROVENANCE_MANIFEST.md, THIRD_PARTY_NOTICES.md, and LICENSE_DECISION.md before any public release.
