# Life-Domain Arc (lifetime curve)

`GET /api/trpc/profile.arc`

## Request

- Base URL: `https://api.asktian.com`
- URL: `https://api.asktian.com/api/trpc/profile.arc`
- Auth: HTTP bearer

The LIFETIME layer for the domain profiler (taxonomy domain-1): computeDomainArc(topic) scores each BaZi Da Yun decade (birth → ~90) for the domain and reads the curve. topic='wealth' (wealth-arc-1): each decade's 財-emphasis (0–100) with a build/hold/guard band + status, the peak-wealth window and staysStrongLate. topic='health' (health-arc-1): a lifetime ENERGY-PACING curve (印/比劫 restorative vs 財/官殺 demanding decades) + peak-energy window — lifestyle pacing, NEVER an illness timeline. Pure function of the birth input; asOf tags each decade past/current/future only. Deterministic, no LLM. OMITTED GENDER DISCLOSED (genderAssumption): the decade direction underneath the timing layer is the male assumption when gender is omitted — a female chart's decades run the other way; the marker is absent when gender was supplied. Symbolic self-insight — not financial advice; window language, never point predictions. Love/… follow with the same shape.

Cost: 10 TIAN Points per call. tRPC procedure `profile.arc`.
