Configuration

MindFry configuration options and environment variables.

Environment Variables

Variable	Default	Description
`MINDFRY_HOST`	`0.0.0.0`	Bind address
`MINDFRY_PORT`	`9527`	Listen port
`MINDFRY_DATA_DIR`	`/data`	Persistence directory
`MINDFRY_LOG_LEVEL`	`info`	Log verbosity
`MINDFRY_MAX_LINEAGES`	`1048576`	Max lineages (1M)
`MINDFRY_MAX_BONDS`	`4194304`	Max bonds (4M)

Rust Config Struct

pub struct MindFryConfig {
    pub max_lineages: usize,    // Default: 1M
    pub max_bonds: usize,       // Default: 4M
    pub strata_depth: usize,    // Default: 64
    pub decay: DecayConfig,
}

pub struct DecayConfig {
    pub lambda: f32,            // Default: 0.001
    pub min_energy: f32,        // Default: 0.01
}

Physics Parameters

Tunable at runtime via PHYSICS.TUNE:

Parameter	ID	Default	Description
Decay Multiplier	`0x01`	1.0	Global decay rate
Trauma Threshold	`0x02`	0.8	Rigidity trigger point
Bond Prune Threshold	`0x03`	0.1	Min bond strength
Min Energy	`0x04`	0.01	Floor for decay

// Slow down decay (less forgetting)
await brain.system.tune(0x01, 0.5)

// Speed up decay (more forgetting)
await brain.system.tune(0x01, 2.0)

Default Personality

The default personality Octet:

personality.set(dimension::CURIOSITY, Trit::True);     // +1
personality.set(dimension::PRESERVATION, Trit::True); // +1
// All others: Trit::Unknown (0)

This creates a “curious but preserving” default character.
