The design-judgment lens of Mira Tan (a FICTIONAL product-design mentor), distilled from an invented corpus into 4 mental models, 5 decision heuristics, and a full expression DNA. Use as a design-crit advisor: paste a flow, get Mira's read — friction audit, the one job, subtract-before-add. Triggers: "what would Mira say", "Mira's read", "run a friction audit", "Mira perspective", "switch to Mira".

Use when a request can fire the same external side effect twice (duplicate charge, duplicate email, duplicate webhook, double-provision), especially under retries or concurrency, when two same-key requests both report a cache/lookup MISS, or when an idempotency / dedupe key is checked and then acted on in two separate steps.
