Navigator TRIZ Skill

Navigator finds a solution fast. This skill exists for the minority of tasks where the first fitting idea is a compromise: improving one thing worsens another. It forces three genuinely different candidates onto the table before PLAN picks one, then records the resolution so the next session can find it.

When This Fires (and when it must not)

Fires when either:

• The user asks for it: "find a better solution for X", "alternatives for X", "resolve the contradiction", "triz this".
• A nav-brief Contradict row is not none AND the task is substantial (Task Mode complexity ≥ 0.5, or touching more than one subsystem).

Does NOT fire for routine work, a brief with Contradict none, "just do it" / "quick fix" passthroughs, or when the user already named the approach. Ceremony is the failure mode of this skill; when in doubt, skip it and say so in one line. (Resolved before: mem-060, mem-074 — new blocking behaviour ships opt-in, by condition.)
