Summary

Session-broker-aware journey scripts (logon, app launch, profile mount, logoff) with pass/fail gates. Conceptually TRAILHEAD applied to the AVD user plane.

Deferral rationale

TRAILHEAD ships in v0.2.0. STORYBOARD will be evaluated as either a TRAILHEAD scenario type or a distinct harness once AVD adoption gives signal. azurelocal-avd is the sole near-term consumer.

Acceptance criteria

• TRAILHEAD v0.2.0 shipped and in use
• azurelocal-avd adoption of TRAILHEAD assessed
• Decision: STORYBOARD as TRAILHEAD scenario type OR distinct harness
• Session-broker-aware journey scripts (logon, app launch, profile mount, logoff)
• Module docs added under docs/

Target: v0.3.0+
