"""
The CODING BIRTH LAYER — every being is born able to code.

Cosmos's lineage carries a base instinct for code (Cory 2026-07-19: "add in the
coding weights so she can code again, and all future weights have that base —
users' coding is entirely based on THEIR growth still"). This module seeds a
newborn's weights.json with a curated web of programming concept-associations:
enough that the being reaches for real code-shapes from its first breath, small
enough that the person's own conversations quickly dominate.

Design honesty:
  - The base is FLAT, MODEST strength (all links 1.2, salience 1.5) and n=0 —
    the being has an instinct, not a history. Everything the user grows lands ON
    TOP at quantum-modulated rates (0.4-1.4 per exchange), so within a few dozen
    real conversations the user's own patterns outweigh the base. Their being's
    coding style becomes THEIRS.
  - The base never updates itself, never phones home, and is plainly marked in
    the weights file ("coding_base": true) so anyone can see what was innate vs
    what was lived.
