/insight-angles

A lens-based, multi-pass discovery engine. Where /insight-explore asks "what are the ways to build this?" and /insight-adversarial attacks for flaws via personas, insight-angles asks "what frames, connections, assumptions, and second-order effects are not yet visible?" — and finds them by pointing the right lenses at the subject. It can run each lens as a cold sub-agent (fresh context, no anchoring) — independence is what makes discovery work, the same reason /cold-review outperforms inline /verify at finding things — and picks cold vs inline per subject, asking only when it isn't sure. Read-only and advisory — it surfaces, never decides or changes anything.

Structured execution spec: protocol.yon. Read it for the canonical rules and step sequence; this file is explanation. The two must stay in sync — if you edit one, update the other and refresh the @STAMP date.

The lens roster (seed, not ceiling)

17 families, grouped by what they perturb. Core = candidate for most subjects; Specialist = domain-triggered. Always also derive dynamic, subject-specific lenses (see below) — the roster is a seed.
