Why use Sol Advisor?
You can ask a model to "build this feature" in one prompt. Sol Advisor adds structure on top of that: it keeps one session honest about architecture and acceptance while a pinned, verifiable worker does the typing.
What structure buys you
Separation of concerns
The architect doesn't also implement and review its own work in the same breath. Roles are explicit.
No silent fallback
If the expected role, model, or reasoning effort can't be confirmed, the lane stops. You don't discover later that a weaker model quietly did the work.
Fresh review
Acceptance runs in a fresh context, so the reviewer isn't the orchestrator rubber-stamping its own output.
Right lane per risk
Use the native Terra / High lane for routine work, or opt into user-visible Luna / Max tasks when you want trackable, visible implementation.
Routing evidence
Spawn metadata (and a read-only inspector when needed) prove which role and model actually ran. Public and local evidence must agree.
A real acceptance gate
The session can't report done until the Sol reviewer returns ship. Fix-first and rethink are first-class outcomes.
