Effect v3

Purpose

Use this as the single source of truth for Effect-related guidance in this repository. Sections are index buckets, not a reading order.

Routing Rules

• Do not read this handbook linearly.
• Pick one target file below.
• Follow See also only if that file is insufficient.
• Read exactly one: pick one target file first; only follow See also if needed.
• Top-level routing: intent → exact file path; sections are index buckets, not reading order.
