nav-triz

# 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.) ## Protocol (one screen of output) 1. **State the contradiction** in one line, technical form ("improving A vs worsening B") or physical form ("X must be both A and not-A"). If you cannot, stop: there is no contradiction, proceed normally. 2. **Ideal Final Result**: what if the function existed with no new code? Name what would have to be true. If reachable, that is candidate 0 and usually the answer. 3. **Reuse inventory**: what already does ≥80% of this? `path:line` or `none found`. 4. **Prio...
