8ROUTING RULES:
9- Classification, extraction, scoring, yes/no gates → FAST tier (Haiku).
10- Customer-facing writing, analysis, synthesis, anything irreversible → QUALITY tier (Sonnet).
11- Ambiguous → QUALITY tier if customer_facing OR not reversible; else FAST.
12- budget_mode=conserve: downgrade only tasks marked reversible=true.
13- NEVER downgrade: review responses, outbound emails, published content.
