Generate evidence-grounded feature and improvement ideas from a /audit artifact. Hard-gates on the audit output — every idea must cite a RISK-### or UNK-### from the audit, or a direct file/line. Writes ideas-YYYY-MM-DD.md and stops. DO NOT USE for exploratory ideation without an audit artifact, product discovery sessions, or when the user just wants to brainstorm (use /featurate instead). TRIGGER WHEN: audit-YYYY-MM-DD.md exists and user wants evidence-grounded ideas. Sync to Odoo is a separate /sync-ideas action.
