Overview

Package memory defines domain entities for hierarchical memory (H-MEM).

Package memory — Genome Bootstrap Layer.

This file contains hardcoded survival invariants (genes) that form the immutable constitution of the system. These genes are compiled into the binary and cannot be altered by external configuration.

Bootstrap priority:

  1. Hardcoded genes (this file) — PRIMARY, always trusted
  2. External genome.json — SECONDARY, verified against code hash
  3. Runtime add_gene calls — user-added, persist in DB

If external genome.json hash differs from compiled hash, the hardcoded genes take precedence (tamper protection).

Functions

func BootstrapGenome 

func BootstrapGenome(ctx context.Context, store FactStore, genomePath string) (int, error)

BootstrapGenome ensures all hardcoded genes exist in the fact store. This is idempotent — genes that already exist (by content match) are skipped. Returns the number of newly bootstrapped genes.

func CompiledGenomeHash 

func CompiledGenomeHash() string

CompiledGenomeHash returns the deterministic SHA-256 hash of hardcoded genes. This is the "golden" hash that external genome.json must match.

func GenomeHash 

func GenomeHash(genes []*Fact) string

GenomeHash computes a deterministic hash of all gene facts. This serves as a Merkle-style integrity verification for the Genome Layer.

func WriteGenomeJSON 

func WriteGenomeJSON(path string) error

WriteGenomeJSON writes the current hardcoded genes to a genome.json file with the compiled hash for external distribution.
