Biological Growth Regime (BGR)

Crystal–Mycelial Engine — RTT / CMH Substrate Phase#

1. Regime Identity#

Regime: Biological Growth Regime (BGR)
Layer: Biological substrate
Role: Establish biological geometry for hybrid and mineral transitions
Operators: P • E • G • M

2. Purpose#

The Biological Growth Regime defines the initial substrate conditions under which mycelial networks form stable routing channels, pulse pathways, and structural memory.
This geometry becomes the template for hybrid infiltration and mineral lock‑in.

3. Substrate Behavior#

Hyphal Propagation#

• Tip‑driven extension
• Branching under nutrient gradients
• Channel formation along stable envelopes

Pulse Signaling#

• Weak electrical pulses propagate through hyphae
• Pulse frequency correlates with moisture and nutrient availability

Structural Memory#

• Branch scars encode historical routing
• Channel thickness reflects growth history
• Pulse pathways become memory‑bearing geometry

4. RTT Operator Mapping#

Propagation (P)#

• P.trace_extend — extend hyphal tips
• P.branch_decision — choose branching direction
• P.route_establish — stabilize channel geometry

Energy (E)#

• E.logic_pulse — generate biological pulses
• E.pulse_sync — align pulse timing across channels

Gradient (G)#

• G.nutrient_gradient — shape growth direction
• G.moisture_gradient — regulate channel thickness

Memory (M)#

• M.route_memory — encode routing history
• M.branch_memory — store branching events

5. MSRM Envelope Requirements#

Moisture Envelope#

Target: 0.55–0.65

• High enough for hyphal extension
• Low enough to prevent uncontrolled overgrowth

Nutrient Envelope#

Target: low‑nitrogen

• Promotes channel formation
• Reduces chaotic branching

Electromagnetic Envelope#

Target: 0.2–0.4 mT

• Supports pulse propagation
• Maintains biological coherence

6. Outputs of BGR#

• Hyphal channels
• Branch scars
• Pulse pathways
• Biological geometry map (bio_map)
• Memory‑bearing substrate ready for hybrid infiltration

7. Transition to HRR#

BGR transitions into the Hybrid Resonance Regime (HRR) when:

• moisture decreases
• ion saturation increases
• resonance field is introduced

This marks the beginning of mineral infiltration and hybrid alignment.
