insight-cross-examine

# /insight-cross-examine Given a **subject** or a **set of subjects**, cross-examine routes by context to the right depth, **discovers the angles and connections not yet visible**, runs the insight battery (`/insight-critique` → `/insight-assess`, plus `/insight-explore`, plus hybrid synthesis), and hands back a **decision surface** — a recommendation over the items and viable hybrids, *plus the insight trail that produced it*. Its thesis: **route → discover angles → expose connections → assess → recommend.** It surfaces the decision either as an **ask-gate** (fired standalone) or **inline** (fired as a sub-step), and never auto-dives into expensive analysis without the handler's consent. > **Structured execution spec:** [`protocol.yon`](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. ## Gate 0 — Stop-first (before any heavy processing) A cheap pre-flight that runs **before** the router and before any sub-skill fires, so a 500-item set or a mis-aimed invocation never triggers the battery. It is an **escalation warning, not a hard stop** — warn the handler, then proceed if they override. Warn + escalate to the handler when: - **Over-large corpus** — a set beyond ~8–10 items, or a subject whose source-gathering would blow a normal read budget. Name the size; offer sampling / fan-out. - **Ill-fit** — the subject isn't a decision/evaluatio...
